Installation of additional metal tile elements. Roof elements made of metal tiles. Video - How to choose a roof passage element

Additional elements for metal tiles allow for correct and reliable installation of the roof and reliably ensure the tightness of the roof. All additional elements can be divided into 3 groups:

Flashings: molding elements for arranging various types of connections.
Passage units: shaped elements for hermetically sealed passage through roof structures of ventilation ducts, antennas, as well as various hatches and light elements.
Products to ensure the safe operation of the roof: snow guards, walking bridges, ladders, etc.

The first group is flashings, running products of various types, made of galvanized steel sheets with a thickness of 0.5 to 0.7 mm and a length of 2 meters. Additional elements are used mainly with a polymer coating of the same color as the profile sheets of metal tiles. The number and types of flashings depend on the complexity of the roof configuration, on how complex the metal roofing units are, on the presence of a drainage system and the conditions of use of the under-roof space.

Eaves part of the roof

For the correct installation of the eaves of the roof, eaves strips and drip edges are used. The eaves strip is attached to the sheathing under the waterproofing layer and on top of the brackets for attaching the drainage system. A necessary condition for a long-lasting roof without ice and icicles is to ensure an air flow to ventilate the roof and remove condensate.

The first problem in the cornice part is solved by a special ventilation perforated tape and perforated sheets of cornice lining (soffits).

Protecting the intake openings with breathable materials allows you to protect the eaves of the roof from the penetration of birds, leaves, and snow sweeping.

The second task - condensate drainage - is solved by the drip strip.

Ridge part of the roof

Additional elements for roof ridges are represented by ridge strips of three types: Straight ridge, figured ridge and semicircular ridge. The straight ridge is designed for roofs of a simple configuration and to protect the joints of metal tile sheets on the ridges and hips of the roof. The figured skate has additional stiffening ribs and an air chamber for ventilation. The semicircular ridge also allows for ventilation of the roof and is more durable. The ridge element must cover the joint of metal tile sheets on the outer edges of the roof, be it the main ridge or the hips. When choosing and installing skates, you should pay attention to the need to remove air vapors. Ridge strips are laid over the joints of metal tile sheets and over the end strips. Installation of ridge elements should begin from the light side with the prevailing wind direction in order to position the open joints of the ridges in the direction of the wind. This will reduce noise and increase the life of the roof. Joints of simple ridge strips should be made with an overlap of at least 150 mm, and joints of semicircular ridges should be made along stamped grooves. The ends of the skates are covered with special end caps.

Additional products for constructing valleys

In the valleys (internal corners on the bends of the roof, also called valleys), additional sheathing is installed, glued with double-sided tape, and then a valley apron is made of galvanized sheet steel with a polymer coating. The overlap of steel sheets is 150 mm. The total width of the gutter is 1000 mm, 500 mm from the axis in each direction. The overhang of metal tile sheets over the gutter is 80 mm. The end sections of the valley junction sheets should be protected with special synthetic gaskets. In order to obtain a neat appearance of the valley and prevent the accumulation of leaves and debris, the valley is protected with an additional top cover.

End (wind) strip

This type of flashing protects the end part of the metal tile roof from direct precipitation, blowing leaves and snow into the under-roof space, and also prevents deformation and tearing of metal tile sheets under the influence of wind. The end strip experiences a large wind load, so the shelves have several bends - stiffeners. The end strip should be attached on top of the tile sheets every second or third wave. On the gable side, a fastening pitch of about 700 mm should be observed, since this side is clearly visible. On top of the ridge, the end strips of the slopes need to be connected to each other.

Junction strips

The junction of metal tiles to wall structures and the passage through the roof of ventilation shafts must be protected with aprons. The upper part of the apron must extend onto the wall by at least 150mm. The junction strips have different profiles and are selected individually for the assigned tasks. Other shoulder straps. When making roof slope fractures, a sloping strip with a drip is used. The bend angle of the bar depends on the angle of the slope fracture. The length of the shelves of such a strip is not less than 150 mm on the side of the tile sheets and not less than 80 mm on the drip side.

Passage nodes

The second group of additional elements are parts for the passage of communications. The use of these elements allows antennas and ventilation outlets to be hermetically passed through the roof. The advantages of use are the durability of the connections, since under the influence of wind load the elements become loose and a home-made connection is more susceptible to destruction and leaks. Instructions for installing communications passage elements are given in the accompanying documentation.

Roof safety devices

The most commonly used safety devices are snow guards. Snow melts off metal tiles like an avalanche, and in regions with stable snow cover, snow retainers should be used. There are two types of snow guards. Tubular and sheet. Tubular snow guards consist of two brackets and two pipes. Products are made of galvanized steel, both with and without polymer coating.

A more economical option for a snow retainer is a sheet one, made from a bent sheet.

Installation of snow retainer brackets should be carried out in the second or third wave of metal tiles from the eaves. Fastening is carried out in the existing sheathing on top of the metal tile wave. Installation of snow retention elements should be carried out using synthetic gaskets, which are included with the snow retention system. Roof fencing elements that prevent people from falling are required when the eave height is more than 7 meters and the slope is more than 12%, or when the height is more than 10 meters and a lesser slope. The fencing brackets are attached to the existing sheathing on top of the metal tiles through a universal gasket at the intervals specified in the product instructions.

Stairs are necessary when there is a difference in roof heights and in some cases for public buildings and apartment buildings for climbing to the roof. The design and fastening of stairs should be selected with the assistance of professionals.

Transitional bridges installed on the roof allow you to safely service the roof, but are not mandatory for use. Mounting kits and mounting instructions are included with all industrially manufactured products.

Additional elements can become a significant part of the budget for roof construction, but the use of these elements will ensure the durability of the roof and save on its subsequent maintenance and repairs. We also recommend watching the video

Laying metal tiles is not a complicated process at all and you can easily do it yourself by following the installation instructions. Manufacturers of metal tiles have provided every step of installation work in their instructions, everything is simple and accessible. If you follow all the rules, you can avoid the bad consequences of poor installation.

Be attentive to hydro- and vapor insulation, do not neglect the protective coatings of wooden structures, and do not skimp on insulation (mineral wool with a density of 30 kg/cubic meter or more behaves best).
Don’t forget about installing a drainage system, snow guards, roof ladders and roof railings. These seemingly optional systems will help protect yourself during roof operation and increase its service life.

During the installation of metal tiles, you will need the following additional elements: eaves strip, lower valley, apron around the chimney outlet, end strip, upper valley, abutment strips, ridge strips, external corners, fencing strips.

Contact us, we will prepare all these additional elements for your metal roofing individually. We will supply you with all the necessary fasteners, including those painted to match the color of your roof. Fastening elements can also be covered with plastic decorative caps.

Our employees will calculate and offer all sealing and sealing materials at competitive prices. You can also purchase touch-up spray cans in the color you require.

Additional elements are an essential part of a metal roof. They are designed to ensure the tightness of adjacent parts, as well as to prevent any debris, dust, insects, etc. from getting under the roof. Additional elements may be needed for the ridge, cornices, gable edges, valleys, internal corners, and pipe passages. In this article we will talk about components for metal roofing, that is, additional elements.

What components are needed

Extensions are galvanized steel strips installed where the roofing material is joined, as well as in transition areas. These products most often have a length of 2 m, and their thickness ranges from 0.4 to 0.7 mm. The width varies quite a lot, and is determined by the dimensions of the mounting shelves used. The additions can be coated with polymers to match the color of the metal tiles, which leads to a slight increase in price, however, such material becomes much more beautiful.

Often, when connecting ridges or upper valleys that are in a visible place, it is polymer-coated products that are installed. They fit best into the overall picture, complementing the color of the tiles. Naturally, if there is an overlap of the joints under the sheets of metal tiles, then in this case we are not talking about decorativeness.

For example, for the lower crowns it is more advisable to install simple galvanized strips without coating. This way you can save some money and still ensure a sufficient seal.

There are the following components for a metal tile roof:

cornice strip;
wind bar;
skate;
valleys;
abutment strips;
snow retainers.

It is worth considering each component in detail.

What is a curtain rod

This product is nothing more than a steel corner used to decorate the lower part of the roof along the entire length of the eaves. The eaves strip is necessary to protect the eaves board from water, as well as to drain it if it is under the roof. One more point - it is necessary so that the cornice line takes on a finished look.

Install such a strip before laying the metal tiles, but after installing the drainage system. The mounting shelf is secured to the sheathing on top of the gutter holders. To do this, you will need galvanized screws, which are screwed in at intervals of 30 cm. For the entire cornice, you will need several of these strips, connected to each other with an overlap of 5-10 cm.

Pediment (wind) strip for metal roofing

This bar is also made in the form of a corner. are carried out along the entire length of the gable overhang to protect the ends of the sheathing and the space under the roof from moisture, various debris, birds and insects, as well as from the effects of wind.

The end strip is attached at the very end of the roofing work, on the metal tiles. Installation is carried out from top to bottom, overlapping the ends of the sheets of roofing material. This one is screwed on with self-tapping screws, which are screwed in every 50-60 cm with an overlapping length of 10 cm.

It is worth making sure that the end strip touches the upper ridges of the roofing material, slightly overlapping them. Thus, by installing a windbreak on the roof, you can protect the bottom of the metal tile sheet from moisture. In addition, the material will stop rattling when exposed to strong winds. To obtain a tight fit, the edges of the roofing material can be slightly bent upward.

The purpose of the roof ridge

Another component for metal tiles is the ridge. A ridge strip is necessary to bridge the joint between sheets of roofing material. Such a joint is formed along the ridge line when connecting the slopes. The ridge is necessary to prevent the penetration of moisture under the roof, various debris, birds and insects. In addition, it is an element of the ventilation system - it supplies air through the ventilation gap under the sheets of metal tiles. This ensures ventilation of the roof components.

There are round and straight ridge strips. The first type requires the installation of conical or flat semicircular plugs.

During the installation of the ridge strip, gaps inevitably appear between the ridges of the roofing material and the fastening shelves. Manufacturers of metal tiles advise sealing them with insulation. However, this approach impairs ventilation. To eliminate this problem, you can install auxiliary pitched or ridge point aerators.

The sealing material is glued to the ridge strip or roofing sheets. Next, install the bar, securing it with self-tapping screws to the top of the wave. Fixation can also be done through the lathing.

The extension of a straight ridge is done by an overlap of 10 cm. The connections of the round ridge strips are made using stamping lines.

Some information about valleys

The complete set of metal tiles with valley strips is necessary to seal the internal corners of the roof. They are a kind of gutter-tray, which is formed inside the corner of the roof along the slope. During the operation of the roof, it will support very large loads resulting from the accumulation of snow precipitation, as well as during heavy rains.

The lower valley has wide bent strips, the angle of which is determined by the conjugation of the slopes. Its installation is carried out before laying the metal tiles.

The planks are fastened to a continuous sheathing assembled from 150×25 mm boards. First of all, waterproofing is laid on the sheathing, after which the lower valley strip is secured with self-tapping screws every 30 cm. In this case, the individual elements are joined to an overlap of 10 cm.

If at the junction of the slopes there is an almost flat angle, it will be somewhat more difficult to seal it. For sealing, you can use porous insulation.

After the sheets of metal tiles are laid, another plank is installed over the formed joint of the internal corner - the upper valley. It is necessary to get rid of water from the inside of the roof corner. The plank also makes the joints presentable. In this regard, the material from which the upper valley is made must have a polymer layer of the same color as the metal tile sheets.

The upper valley is placed on the end of the inner corner and secured with self-tapping screws so that they do not pass through the middle of the lower valley strip. Otherwise, the tightness of the connection will be compromised, and the risk of leaks will significantly increase. The gaps formed between the top strip and the roofing are covered with porous insulation.

Junction strips are an indispensable accessory

Such components for Monterrey metal tiles are installed where joints between the roof and other surfaces are formed - a chimney, a wall, a ventilation shaft and parapets.

Based on the locations in relation to the sheets of roofing material the abutment strips will be installed, they can be upper and lower. The bottom strip is made in the form of a corner with inverted longitudinal edges, which makes it possible to qualitatively fix the element in a wall made of concrete or brick. The top bar has rolled edges.

Both types of junction strips are used in places where sheets of metal tiles meet the edge. To obtain maximum joint tightness, internal and external aprons are created using such strips.

The contour is made in this way:

Lay a layer of waterproofing, making sure that it extends more than 5 cm onto the pipe wall. The sections are attached to the pipe using adhesive tape.
Proceed to installing the inner apron from the bottom of the pipe. The lower junction bar is applied to it, and a line is drawn.
Along this line, a slightly beveled upward groove is made to a depth of approximately 1.5 cm. At the same time, make sure that all actions are carried out with the utmost care so as not to damage the seams in the brickwork. Making grooves between bricks is strictly prohibited.
After this, the curved edges of the internal abutment strips are inserted into the groove, and the seam is sealed with a heat-resistant sealant.
From below, under the inner apron, a “tie” is placed. It can be connected both to the valley and to the cornice. This element will allow water trapped between the apron and the roofing to flow down the slope.
The planks are fastened to the sheathing and pipe walls using self-tapping screws.
In the same way, the abutment strips are secured to the side and top of the pipe.
Roofing sheets are installed on the inner apron.
The upper and lower abutment strips are fixed in the same sequence. The external apron, by and large, has a decorative purpose and is necessary to hide the cuts of metal tile sheets.

The connection to the wall is made in the same way:

Place the waterproofing material on the wall 5 cm upward.
Place the top strip on the wall and make a mark along its top edge. After that I make a groove along it.
The upper edge of the adjacent strip is inserted into the groove, after which the groove is sealed with sealant.
Take self-tapping screws and use them to sew the bottom flange of the plank to the sheathing.
The gap between the plank and the roofing material is closed with a sealant.

Snow guards

Accessories for metal tiles such as snow retainers are barriers to prevent snow and ice from falling off the roof.

Snow guards come in tubular, lattice and corner types.

Tubular products are brackets that are attached to the roof. Two rows of pipes are passed through the holes in them. This type of snow retainer is used most often.

Lattice types also have brackets, between which there are not pipes, but lattice elements made of pipes or angles.

Corner barriers are made in the form of rigid steel curved corners. Used in places where slopes have a slope of up to 30°.

Installation of tubular snow retention systems is carried out in the following sequence:

Calculate the placement of barriers on the roofing material. This must be done at the stage of installation of the sheathing.
The brackets are fastened at the bottom of the wave using self-tapping screws. The gap between the brackets varies and ranges from 50 to 100 cm.
Pipes are threaded through the holes in the brackets, after which they are terminated with plastic plugs.
If the length of the slope exceeds 550 cm, then install a second row of snow barriers, maintaining a distance of 250-350 cm from the first.

The same method is used to install lattice systems.

Corner snow guards are mounted in this way:

An underlay carpet is installed on the sheets of metal tiles, and the fastening is carried out at every second top of the wave.
The snow retainer is attached to the lining corner using long self-tapping screws. They are screwed through the wave, at its highest point.
If required, install an additional row of barriers.

Finally, it is worth noting that, despite the high price of a larger number of components for metal tiles, it is advisable not to save money on them. If you use high-quality additions, this will not only give your building an ideal appearance, but will also make the roof as durable as possible, so that during its operation you will spend a minimum of time on its maintenance.

The popularity of metal roofs is explained by their reliability, durability and beautiful appearance. Additional elements used for metal tiles differ in their shape, size and purpose. They are necessary to protect against dust and moisture getting under the roof, and also allow you to decorate the roof and give it a finished appearance. For the manufacture of metal roofing elements, the same materials are most often used as for the main covering.

The main elements of a metal roof

In order for a metal tile roof to serve for a long time and reliably protect the roof and house from the negative effects of external factors, all joints, abutments and eaves must be covered with special elements. They are usually made of the same material as the main covering, and not only protect the roof from leaks, but also significantly improve its appearance.

Additional elements allow you to increase the tightness and durability of the roof, as well as give it an aesthetic and finished look

When creating a roof made of metal tiles, it is imperative to use additional elements that allow you to solve the following problems:

increase the strength and tightness of the roof at the joints;
hide the joints and give the coating an aesthetic appearance;
protect the under-roof space from moisture, dust and debris;
give the roof the necessary performance characteristics, thereby increasing its durability.

Construction stores offer a large selection of additional elements for metal roofing, which allow you to equip a roof of any complexity.

Additional elements for metal tile roofing are usually made of galvanized painted steel. When purchasing them, you can save money, for example, by using a product made of ordinary galvanization for the lower valley, and a polymer-coated part for the outer valley.

Those elements that are located in plain sight must have a polymer anti-corrosion coating and correspond to the type of the main roof. This way you can not only ensure the tightness of the roof, but also make the roof beautiful and attractive.

In order for a metal tile roof to serve as long as possible, all joints and joints must be covered with additional elements

Gutter holders

Gutter brackets can vary in type and size, as well as the material from which they are made. Gutter holders can be made of plastic or galvanized iron with a protective polymer coating. Usually they are chosen to match the gutters, but they can also be of a contrasting shade - it all depends on the preferences of the owners.

There are three main designs of gutter holders:

Long - have an elongated mounting strip, mounted to the rafters or sheathing before laying the main covering.
Short ones also have the form of a hook, the mounting base of which is combined with the rear part. Such brackets are usually installed after laying the roofing material and are attached to the front board or to the ends of the rafters.
Universal - they are collapsible elements with a short holder and a removable strip, so they can be used at any stage of creating a roof.

The correct choice of holders eliminates unnecessary actions and costs during their installation. For example, if a roof is being repaired, it is better to use short or universal holders. When constructing a new roof structure, preference should be given to long hooks, as they provide a stronger and more reliable fixation of the gutters.

The method of attaching brackets for gutters should be selected based on the capabilities provided by the roof structure

It is better to purchase gutters and brackets for attaching them in one place and at once. The installation step for metal holders is 50–60 cm, and for plastic ones – 30–35 cm.

Gutter for water drainage

A metal roof, like any other roof, will not function properly without gutters. These elements serve to collect and drain melt and rain water from the roof surface.

Gutters vary in the material they are made from. For a roof covered with metal tiles, gutters made of:

Metal. This is the most popular option, as they not only reliably drain water, but also have high strength, rigidity and durability. Such elements have a special coating that protects them from the negative effects of aggressive environments, so with proper use they will last 30 years or more. The disadvantage of metal products is their heavy weight.
Plastic. They combine beautifully with both metal tiles and other types of roofing, are not afraid of corrosion and are light in weight. They also have disadvantages: they make a lot of noise and can crack when water freezes.

According to the cross-sectional shape, gutters can be:

round;
oval;
square or rectangular.

If your climate zone has little rainfall, then you should not purchase wide rectangular gutters. A universal solution is considered to be round products, the diameter of which is determined taking into account the region of construction.

Most often, round gutters are used on country houses, the diameter of which depends on the region of construction.

The eaves strip is necessary to protect the front board from moisture. It is located under the edge of the metal tile and is installed on the finished sheathing immediately before installing the finishing coating. This part of the roof is usually chosen to match the color of the main roofing material, but sometimes people who prefer unexpected solutions install contrasting additional elements that sharply distinguish the building from a series of similar structures.

For the manufacture of cornice strips, steel sheets with a thickness of 0.4–0.5 mm are used. Plastisol or polyester is usually used as a coating. The standard length of the planks is 50–60 cm, their number is calculated based on the size of the roof and the amount of overlap.

The cornice strip is attached to the front board with self-tapping screws, which are screwed in in increments of 30–35 cm.

The eaves strip is attached to the front board with an inclination towards the gutters

Another additional element is the junction strip. It is necessary to ensure insulation of the roof in places where it adjoins pipes, ventilation shafts, parapets, etc. This element performs an important protective function; it creates a tight and reliable connection through which water cannot penetrate into the under-roof space.

There are two types of junction strips: upper and lower. The lower strip is mounted under the metal tile, and the upper one is mounted above it. In addition, such elements can be straight, having an obtuse, acute or right angle of conjugation.

The junction strip is installed at the exit points of chimneys, ventilation shafts and similar elements

The abutment strips are made from sheet steel; they are usually matched in color with the base coating. Fastening is done using self-tapping screws with sealing washers. For additional sealing, sealant or special seals are used.

Valley roof

The end strip protects the edges of the sheathing and the under-roof space from moisture and gusts of wind and gives the building a finished look

A metal tile roof protects the house well, but this material does not “breathe”, so it is necessary to provide high-quality ventilation of the under-roof space. To do this, ventilation outlets are installed that look like small chimneys.

Ventilation of the under-roof space can be continuous or targeted. The organization of continuous air exchange is carried out before laying the tiles. When using spot ventilation, air flows are directed to specially equipped outlets, which are installed on the roof next to its ridge.

For a roof with an area of up to 60 m2, one ventilation outlet will be sufficient; for larger roof sizes, several will be required. When the roof has a complex shape, ventilation outlets must be installed near each ridge.

The ventilation outlet must be installed at a distance of at least 0.6 m from the roof ridge

The installation location of the ventilation outlet is chosen at the discretion of the owner, but in any case it should be no further than 60 cm from the ridge. It is not recommended to install two such elements on one sheet of metal tiles.

When choosing a ventilation outlet, you need to pay attention to the following points:

The profile of the ventilation outlet cover must correspond to the profile of the roofing material;
the colors of all roof ventilation elements must match;
The kit must include fasteners, a template and overlays;
the larger the pipe diameter, the greater the throughput of the element, but also the higher its cost;
the presence of additional functions (this may be a built-in level that simplifies the installation process, a mechanical or electric fan) affects the ease of installation of the element and its price.

Sewage outlet for metal tiles

If the house has a sewer system, it is necessary to provide for its ventilation, for which a drain pipe is installed. It is a continuation of the riser and leads to the roof. You cannot combine the exhaust pipe with the ventilation system of the house, and it is also strictly forbidden to combine it with the chimney.

Sewage outlets installed on metal roofs are usually made of plastic and have a deflector that allows air to be removed more efficiently. There are sewer outlets with a built-in electric fan. The installation of these elements is carried out in the same way as ventilation outlets.

The sewer outlet must not be installed close to windows or balconies.

Output for antennas and electrical cables

If it is necessary to install an antenna in places where wires pass through the roof, it is necessary to ensure tightness, for which special outlets are used.

Pass-through elements are universal and can be used for both metal tiles and other coatings. They are made of elastic material, so they retain their shape and provide tightness under both mechanical and thermal influences. The antenna or cable output retains its properties at temperatures from -55 to +135 °C.

The outlet for the antenna or electrical cable has a soft base that takes the shape of the metal tile profile and ensures a tight connection

There is a large selection of sizes of pass-through elements, so they can be selected for cables of any diameter. The flange of such outlets is made of soft material; it can take the form of metal tiles, corrugated sheets or other covering.

Features of metal tiles as a roofing covering

Metal tiles are one of the most popular and affordable roofing materials. The full width of the standard sheet is 118 mm, the usable width is 110 mm, and the length can vary from 0.5 to 8 meters. For the manufacture of metal tiles, steel with a thickness of 0.4–0.5 mm is used, and the thicker the sheet, the longer its service life and the higher the cost.

The service life of a metal tile roof is more than 60 years, it is non-flammable, durable, reliable and beautiful. Thanks to the wide variety of colors, this material can be used in any design projects. Metal tiles do not require a large roof slope, only 14 degrees is enough, so it is used on single-pitched, gable and other types of roofs.

The metal tile sheet is treated with several layers of protective coating, which ensure durability and a presentable appearance of the material.

For the manufacture of metal tiles, galvanized or galvanized aluminum steel with a polymer coating is used; copper sheets are less commonly used. This is a lightweight covering, a square meter of which weighs between 3.8–4.8 kg, so it does not require a massive rafter system and sheathing, which saves money.

To more reliably protect the sheets, they are covered from below with a layer of varnish 7–10 microns thick, and on top with a layer of polymer 20–200 microns thick, which can be used as:

Polyester. This is the most common and cheapest polymer, which can be glossy or matte, tolerates temperature changes well, but is afraid of mechanical damage.
Pural. It has significantly higher strength than polyester, so it is not afraid of damage from snow or ice, withstands chemical influences well and can be easily dyed if necessary.
PVC based plastisol. The thickest and most durable coating that has an embossed surface, so the material treated with plastisol is more reminiscent of natural tiles.

Table: comparison of characteristics of various metal tile coatings

Coating	Polyester	Matte polyester	Plastisol	Pural
Surface	smooth	smooth	embossing	smooth
Coating thickness, microns	25	35	200	50
Primer thickness, microns	5–8	5–8	5–8	5–8
Thickness of protective varnish (back side), microns	12–15	12–15	12–15	12–15
Maximum operating temperature, °C	+120°	+120°	+60–80°	+120°
Color fastness	****	****	***	****
Resistance to mechanical damage	***	***	*****	****
Corrosion resistance	***	****	*****	*****
Weather resistance	***	****	**	****

Based on the combination of properties, the best coating for metal tiles is pural.

The main disadvantage of metal tiles is their noise during rain and low thermal insulation performance. Therefore, a roof made of this material must be heat and sound insulated.

Lightning protection is a mandatory element for a metal roof. Lightning rods are connected through bends to grounding conductors using a welded or bolted connection. The presence of lightning protection allows you to reliably protect the house and all its residents from damage by discharges during a thunderstorm. If this is not done, then a lightning strike that hits the roof can create burns in it, as a result of which the roof structure can catch fire.

Lightning rods can be mesh, cable and rod types. Their choice depends on the height of the building, the presence of tall trees and buildings nearby, but the main factor is the thunderstorm intensity of the area.

The most common type of lightning protection is a lightning rod in the form of a rod, which is connected to a grounding conductor through current conductors.

Most often, a metal rod is mounted as a lightning rod, which is attached to the highest point of the roof; a conventional metallized cable is used for the current conductor. For a metal roof, you can simply attach two wires to each slope and ground them. For a one-story house, the ends of the wires are dug into the ground to a depth of 1.8–2 meters. This protection option is only suitable if there is a layer of non-combustible materials between the roofing metal sheets and wooden elements.

Special catchers can be installed on a metal roof, the thickness of which should be 4 times the thickness of the metal tile. For every 10 m2 of roof, it is recommended to install one catcher measuring 80x80 cm. However, it should be taken into account that such a design spoils the appearance of the roof.

One of the biggest disadvantages of metal tiles is its low sound insulation. During heavy rain, noise will be heard in the attic and even on the first floor of the house. To make living in such a house comfortable and safe, it is necessary to properly soundproof a metal roof.

The main causes of noise:

improper installation of the sheathing, when boards of different thicknesses were used, which is why it was not possible to achieve a tight fit of the metal tile sheets;
insufficient number of fastening elements, which is why it was not possible to achieve the required rigidity of the metal tile. For 1 m2 of metal tiles you need to screw in 8 screws;
small roof angle - the smaller it is, the greater the noise.

To ensure the maximum level of sound insulation of a metal tile roof, the following measures must be taken:

To ensure sound insulation, you can use any materials with a sound absorption coefficient greater than 0.4. For example, for mineral wool it is 0.7–0.95.

Ridge for metal tiles

The ridge strip is located at the very top of the roof and protects the junction of the slopes from the penetration of water and foreign objects

To ensure maximum tightness, before installing the ridge strip, seals are installed at the junction of the slopes. They can be self-expanding, profile and universal. The ridge strip can be straight, semicircular or mortise.

It is best to purchase metal tiles and additional elements from one manufacturer. Installation of the ridge involves the use of the following elements:

ridge strip;
lightning rod holder;
ventilation tape;
sealant;
fastening elements.

Installation of a ridge for metal tiles

To perform the above work you will need:

fasteners with rubber washers;
safety rope and ladder to securely secure to the roof;
mounting belt;
screwdriver;
ridge strip.

It will be inconvenient to carry out these works alone, so you must invite an assistant. Installation of the ridge strip is carried out in the following sequence:

Check the connecting line of the slopes for evenness. An error of no more than 2 cm per meter of length is allowed, otherwise it will not be possible to install the skate properly.
Regardless of the width of the ridge strip, seals are installed at the place where it adjoins the roofing to protect the under-roof space from moisture.
Ridge strips are installed with an overlap of about 5–10 cm

How to attach a ridge to a metal tile

When fixing the ridge strip to the metal tiles, you must use self-tapping screws with a rubber head. They are installed on the crest of the wave. Self-tapping screws cannot be screwed tightly and installed very often or, conversely, rarely. If fasteners are installed frequently, the ridge strip will begin to bend in a wave. If they are placed sparsely, the skate will not fit tightly and flapping. It is necessary to choose the optimal middle at which the ridge strip will sit tightly and evenly. This is done experimentally, checking after some time the evenness and reliability of fastening the additional element to the roof surface.

Despite the fact that the cost of metal tiles is quite affordable, the price of the additional elements used will be significant. Experts do not recommend saving on them, since only the correct use of high-quality additions will make it possible to create a durable and beautiful roof that will reliably protect your home for many years.

The variety of roofing coverings gives today's consumers a wide range of options to choose from.

But those who want to purchase high-quality and at the same time aesthetically attractive material should take a closer look at one, which fully complies with the specified parameters.

And here some may ask: what is this material?

Metal tiles are one of the types of profiled sheets, made of thin galvanized steel and equipped with colored polymer coating that performs a protective function.

The material is manufactured using high-tech equipment, which allows the profiling method to imitate rows of natural tiles on steel sheets. To perform high-quality installation of metal tile roofing, additional elements are used that are installed in certain places. The types, characteristics and installation of these structural components will be discussed further.

The installation of a metal tile roof includes the following additional parts:

End strip(aka wind) - installed to protect the pediment from wind loads. Ensures the safety of fasteners (during operation they will not become loose) and protects the structure from moisture penetration.
Lower valley plank– used to drain water from the joints between slopes. Prevents moisture from penetrating into the under-roof space.
Upper valley cover– covers the edges of the metal tiles at the internal joints of the slopes.
– installed at the top of the roof and at its external joints. It protects the under-roof space from dirt and moisture getting into it, and also additionally keeps the covering sheets from being torn off by the wind.
Cornice strip– protects the front board from sedimentary moisture.
Kapelnik– installed to remove moisture (condensation) from waterproofing.
Junction strip– used to seal the coating in places where it adheres to roof elements (for example, a wall or pipe).
– protect the drainage system from snow falling from the roof.

Additional elements for roofing

Now a little more about each of these elements.

End (wind) strip

Wind strip for metal tiles ( aka end strip for metal tiles) is made of galvanized steel 0.55 mm thick and equipped with a polymer or composite coating. The plank is presented in the form of a corner with curved edges, and can also be equipped with ribs located on a plane, due to which the product acquires additional rigidity. The standard length of the part is 200 cm.

Due to the fact that this roofing element protects the structure from moisture and wind, it is also called a wind bar.

Installation The end strip of metal tiles is performed as follows:

Measure the length of the ends of the slopes, based on which the required number of whole parts is prepared. If necessary, the last element is cut to the required size.
Installation is carried out from the bottom of the slope to the top. The parts are overlapped with an overlap of at least 5 cm.
The plank is applied so that it is located above the sheathing layer to the height of the tile wave.
The part is secured with self-tapping screws, screwing both sides. The pitch between fasteners should be 0.3-0.5 m.

Cornice strip for metal tiles

To manufacture this product, the same metal and the same technology are used as in the production of metal tiles. A layer of polymer material (plastisol or polyester) is applied to galvanized steel 0.5 mm thick. The standard length of the plank is 0.5-0.6 m, width 20 cm. Part completed in the shape of a corner.

Before you begin attaching the cornice strip, a frontal plate should be installed, which is attached with galvanized nails to the rafter legs. The front board should be as level as possible, which will greatly simplify installation work.

Installation metal tile eaves strip:

The cornice is hemmed with tongue and groove boards or corrugated sheets.
A support beam is attached to the wall of the building, which will serve as an auxiliary support for filing the eaves overhang.
Gutter holders are attached to the sheathing.
After this, a cornice strip is installed, which is placed on top of the brackets. It is attached with self-tapping screws to the sheathing. The distance between fasteners should be at least 0.3-0.35 m.

Cornice strips must be installed with overlap no more than 10 cm.

Kapelnik

Dropper for metal tiles - this is essentially the same cornice strip, only it is located in a different place unlike the previous version.

The purpose of the drip line is to protect against the penetration of moisture flowing down the sheets of metal tiles (see photo above).

The drip edge is installed along the edge of the roof slope and is attached to the rafters in front of and, accordingly, to the counter batten and.

To fix the parts, use self-tapping screws, screwing them in increments of 30-35 cm.

Endova

Valley strips (gutters), as well as metal tiles, are made of galvanized sheet steel coated with a layer of polymer material. For high-quality installation, especially if the roof deck is not continuous, it is better to purchase products with a thickness of at least 0.7 mm. The width of the part depends on the length of the plank and the width of the lining and can range from 30 to 60 cm.

NOTE!

Elements with a width of 30 cm are recommended to be used when the length of the valley is no more than 4 m or for arranging simple slopes. The optimal amount of overlap of metal tiles over the bar is 25 cm. This applies to the lower valley. The size of the top part is not particularly important, since it is used only as a decorative element.

Installation valley planks includes the following steps:

Before you begin installing the elements, you need to make sure that the waterproofing material is intact.
A continuous sheathing of boards is installed in the valley, on top of which waterproofing is laid.
Attach brackets for the drainage system.
Install the cornice strip.
Install the gutter sheets from bottom to top, securing them with roofing screws. All parts are laid with an overlap of 20-30 cm. The protruding edges of the planks are cut off, after which the cut areas are treated with a special painting compound.

Endova for metal tiles

Lay sheets of metal tiles on slopes adjacent to the valley.

The joints of the sheets are closed if necessary. upper valley linings. They are laid with an overlap of at least 10 cm.

CAREFULLY!

You cannot screw the screws in any closer, less than 25 cm from the valley axis.

Snow guards

These elements come in several species:

tubular;
lattice;
snow retainers made of logs;
corner;
tow ropes

Now let's talk about each one in order.

Tubular

This type is a structure made of brackets with pipes inserted into them. The height of such a barrier is 15 cm. The brackets themselves have the form of vertical plates equipped with holes for pipes. Tubular snow guards are attached to the roof slope with metal screws. They are screwed into holes located on the horizontal shelf, which is located at the bottom of the bracket.

Lattice

Lattice structures consist of brackets with vertical grilles attached to them. The products are made of galvanized steel and are available in various colors, which allows them to be matched to the color of the roofing. The height of the gratings can be different - from 50-70 mm to 150-200 mm. Such barriers are usually installed on long, steep slopes to ensure that snow layers do not fall.

Log

The structure consists of logs attached to special hooks, which are fixed to the sheathing or. Today, barriers with wooden logs are practically not used. They were replaced by products made from large diameter pipes. Such structures effectively retain snow and are able to withstand significant loads.

Corner designs

The products are made in the form of corners made of thin sheet steel and represent the most budget option. Installed to retain small volumes of snow. They are attached using shelves located at the bottom of the barrier and self-tapping screws that are screwed into the upper wave of the sheet. The height of the structure is 40-60 mm. As a rule, such snow retainers are mounted on roofs whose slope does not exceed 30 degrees.

Bugeli

These elements, made in the form of hooks, by themselves are not capable of holding the snow mass in any significant volumes. Therefore, it is most advisable to use as auxiliary elements when installing tubular and lattice barriers.

Other metal roof components

Along with the above elements of the roof, an equally important role in its arrangement is played by such additional elements of metal tiles as skates, covering the external joints between the slopes, as well as abutment strips, which cover the joints of the roof covering with a wall or .

There are skates the following types:

semicircular - most often installed on roofs with two or four slopes, at the places where they join;
rectangular - suitable for almost all types of roofs;
narrow decorative - used more as decoration than as protection;
Y and T-shaped - serve as a complement to rectangular skates and are used to connect them to each other.

Ridge for metal tiles

The abutment strip for metal tiles is made of thin steel and has the shape of corners. The horizontal part of the part is attached to the roof, the vertical part - to the wall of the building or to the pipe(depending on the place of application), thereby closing the joint between the roofing material and the adjacent building element.

Conclusion

The tightness of the roof depends on the correct installation of additional roofing elements made of metal tiles, when installing which all overlaps must be observed and screws must be screwed in at the recommended distance. If you don’t have the skills to do the job, it’s best to turn to specialists to avoid damage to the material and leakage of the roof.
