Roof dismantling stages. Dismantling a roof with wooden rafters and a sheet steel roof using a tower crane Is it possible to repair a roof from a corrugated board and how to do it

At first glance, the dismantling of a slate roof, a roof made of corrugated board or metal roofing can be attributed to the type of work that does not require any professional skills, especially if the old roof will no longer be used for its intended purpose. However, as practice shows, this is not the case. The quality of the installation of a new roof completely depends on the professional level of the dismantling of the roof. Failure to comply with the technology during dismantling work can be fraught with the most undesirable consequences, starting with damage to the rafter system due to improper work, ending with partial destruction of the roof. It only says that such a task should be performed only by professionals who know and take into account the most varied nuances that are inaccessible to the common man in the street, and who own the appropriate equipment.

Dismantling of a soft roof. Stages of work

Any process, as a rule, consists of several stages, from the quantity and complexity of which the price also varies. Dismantling the soft roof was no exception. We will list them below. So, this process consists of:

  • inspection of the object and assessment of its condition,
  • dismantling of roofing,
  • dismantling of insulating material and protective membranes,
  • removing the crate,
  • troubleshooting and replacement of rafters and support beams.

Also, the price includes the removal of the resulting construction waste.
When replacing the roofing with a different type of coating, it is necessary to carry out all the steps. With partial repairs, only some of them can be performed. Performing a partial dismantling of the roof, the prices will be formed according to:

  • the amount of work to be done,
  • labor intensity of the process,
  • the quality and urgency of the services.

To perform the fastest, safest and most high-quality dismantling of roofing material, contact the specialists of MosStroyAlliance. We will provide favorable conditions for cooperation with the highest quality of all work.

Dismantling the roof is not as easy as it seems at first glance. This requires special training.

Dismantling the roof is a rather difficult task that requires special training.

What is the dismantling of the roof covering for?

First you need to figure out what the dismantling of the roof is for.

  1. During a major overhaul of a house or roof. If the premises under the roof are not repaired, the roof is dismantled in parts, after which a new roof is installed.
  2. Often the demolition of a building is carried out by blowing it up or by means of an excavator, however, there are cases in which these methods are not suitable due to the density of the building or other factors. In such cases, it is necessary to disassemble the building carefully. The roof covering must be dismantled in stages, in the process of removing construction waste.

To dismantle the coating, you can contact a company that specializes in this, or you can carry out the process yourself.

Steps to take to dismantle the soft roofing

It is recommended to dismantle the soft roof in a cool period of time, when the outside temperature does not exceed 20 degrees Celsius. The reason is that a soft roof consists of bitumen and, when heated, can change its properties, become more viscous than brittle. This can make the process much more difficult.

Inclined rafters are disassembled according to the principle of removing free-lying elements, after removing the metal fasteners: staples, pins, twists, etc.

There are several ways to remove the soft coating:

  1. Using a wall chaser can speed up and simplify the removal of the roof if the roof covering is more than 3 cm.
  2. Using a roofing ax (an ordinary ax that is welded to a thick pipe with a diameter of 3-4 cm), you can chop the roofing layer into squares.

After the roofing has been square-cut using one of the selected methods, it must be separated from the cement screed or slabs using an ax. All this will need to be thrown into a construction container. It should be said that the process is not as easy as it might seem at first glance, and its complexity will depend on the number of layers of the old roof.

One way or another, it is important to note that the quality of the new roofing completely depends on how the preparatory work was carried out and the old roof was dismantled.

Steps to take to remove a pitched roof

Dismantling the roof should begin with preparatory work:

  1. It is necessary to secure the attic with temporary racks and girders.
  2. All communication line devices (television or radio antennas) must be dismantled.
  3. All plumbing devices, electrical wiring must be dismantled.
  4. Disassemble the chimneys.
  5. Remove all advertising structures.
  1. Dismantling the roof should be started by removing the coating near pipes, walls and other parts.
  2. To disassemble the metal tile, you need to remove the ridge of the linings of the wind and valley elements. The sheets of metal tiles themselves are disassembled in order from top to bottom. After that, it is necessary to dismantle the drainage system and the lower valley.
  3. For layered rafters, you need to remove all metal parts, then remove free-lying elements.
  4. For disassembling rafters, formwork and lathing, it is worth using a portable electric chain saw, an ax and a crowbar. If there is, you need to leave every 5-6 battens in order to avoid the collapse of the trusses. After that, you need to remove the remaining lathing bars, tie up the truss and load it with a crane onto the construction site or immediately completely onto road transport.
  5. All materials that have been disassembled, at the end, must be folded into bags and stored in order to be able to transport it to the warehouse.

Required composition for the job

Dismantling of the roof should be carried out by a team of two roofers, and dismantling of the rafter system by a team of two or three carpenters and one rigger. All workers must be secured to the roof with safety harnesses.

Any homeowner wants to see their home warm, dry and comfortable. This largely depends on the condition of the roof. If something is wrong with the roof, then the problems one after another will begin to make themselves felt. So the issues related to its current, and even major repairs, one way or another, cannot be avoided.

Many people wonder what is better, permanent repair or replacement of the roof. From a budget point of view, it is undoubtedly preferable to patch it up carefully. However, as practice shows, frequent minor repairs are not particularly conducive to improving the state of the structure: it continues to wear out, and cracks only multiply. A more rational option would be a complete dismantling.

On a note

In fairness, it should be noted that the need to update arises not only for a problem roof. A new roof is mounted, for example, during the reconstruction or redevelopment of a house.

When a new roof is needed

A pretty convincing argument for replacing the roof of a garage or residential building will be a wet spot that spreads across the ceiling during heavy rain, not to mention water dripping from its surface.

An annual preventive inspection of the roof and rafter structure will allow you to identify the scale of repair work and develop, if necessary, a strategy for replacing the roof with your own hands:

  • remove the cover completely or use it as a backing for a steel sheet.
  • test the condition of the supporting structure, including the lathing;
  • check the consistency of the diagonal measurements, otherwise, due to violations in the rafter system, you will get different overhangs.

Repair work involves three possible versions:

1 If we are talking only about cracks in the roofing, and the damage did not affect the rafter system, then it will be enough to change the coating to a new one, for example, replace it with. 2 If rot or fungus is found on the crate under the roof covering, then the frame will also need to be repaired. 3 And finally, in case of serious damage to the rafter system, thermal insulation, holes in the flooring, we are dealing with the most difficult option. Here, a complete reconstruction is required, since, unlike the previous case of damage to the thermal insulation layer, it is sufficient to justify the replacement of the roof insulation. The significant scale of the work leads to an increase in cost. The price for 1m 2 will be formed from the total amount of all expenses for dismantling, purchase and installation of new material.

Dismantling

Many people prefer to change slate to corrugated board. This choice has its advantages. Professionals:

  • are lightweight, therefore they do not require reinforcement of the rafter system;
  • resistant to mechanical and natural influences;
  • incomparably more durable than slate;
  • they can be laid independently and reliably protect the roof from leaks;
  • can be considered a budget coverage, with the exception of pural-coated models.

Installation diagram

  • If possible, carefully dismantle the slate, trying not to damage the rafters.
  • They inspect the roof for replacement or repair of some sections of the supporting structure: replace the rotten ones, impregnate the wood.
  • Arrange a vapor-waterproofing: the film is laid with an overlap without much tension.
  • As thermal insulation, polystyrene foam plates are most often used either.
  • The corrugated board is mounted with an overlap in one or two waves, starting from the end part. On a flat roof, sealant is applied to the overlaps.
  • For fixing the corrugated board, use only self-tapping screws equipped with rubber gaskets (with the exception of the valley). This is necessary to completely protect the structure from moisture.

    This question arises when old structures become unusable, or the roof needs to be updated for aesthetic reasons. When renovating fairly old houses, it is likely that the roof covering will have to be removed.

    • When examining the frame, special attention should be paid to the condition of the rafters. The roof is quite maintainable - any part is replaceable. In this case, additional strength clamps are used. For this, boards are suitable, with which you can temporarily connect existing beams that cannot be dismantled. After that, you can safely remove low-quality rafters, since the frame will definitely not collapse.
    • Mauerlat requires no less attention. If signs of decay are found, the damaged parts must be cut out and new ones inserted and securely fixed with plate pads or using tie bolts. In principle, the Mauerlat can be completely replaced with a new one, carefully dismantling in parts with replacement with new ones around the perimeter.
    • Having repaired the roof frame, the covering is re-laid.

- dangerous and time consuming, and not only because they are performed at a height. For safety reasons, to eliminate the risk of injury to people and collapse of the structure, we strongly recommend that you engage in this work, and the information provided is for information only!

Features of dismantling works

Dismantling of the roof is carried out during major, partial repairs when replacing the old coating with a new one. There are many reasons for this - wear or damage to the coating, redevelopment, extension of the attic, etc. Also, the dismantling of the roof is carried out when the entire building is demolished.

In some cases, it is possible not to resort to dismantling the entire roof: it is enough to replace the outer material, but only on condition that the strength of the existing rafters is recalculated and the load that the new roof will create is estimated. But if we are talking about redevelopment, completion of a new floor or part of a building, as well as roof wear, dismantling is indispensable: all the elements are disassembled, including the rafter system and the Mauerlat.

Before carrying out work, it is developed, which depends on the type of roof, the quality and strength of materials, the number of storeys of the structure, the area of ​​the roof and a number of other features. The assessment of the condition of the roof is always carried out on site - if the roof is old and emergency, additional safety measures will be required. Isolation of the site is mandatory, excluding the access of third parties to the work site.

Algorithm for roof dismantling

In order for the process to proceed constructively and quickly, you should adhere to a well-thought-out scheme. Deviation from the work plan is possible in the event of force majeure, and in other cases it is excluded.

Attention!
Safety engineering is a mandatory requirement at all stages of work, which consists of safety for workers, people and structural elements of the building. In addition to workwear and safety footwear, personal protective equipment for hands, head and respiratory organs is required (a lot of dust is generated during work)

Approximate work plan:

  • Removal of the skin, which is carried out taking into account the characteristics of the coating.
  • Removing the battens and removing the insulating layers. The work is carried out in turn, depending on the condition of the roof and materials. The lathing is removed very carefully and carefully so that not a single element remains. The insulating layers are also removed one after the other.
  • Analysis of the rafter system. Additional beams are removed first, and load-bearing beams last. The connecting elements are carefully cut with a saw.
  • Removing the insulation.
  • Sorting of materials and removal of construction waste.

When disassembling the roof of private houses, the volumetric elements of roofing materials are lowered after preliminary fixation with strapping material, carefully and slowly. When it comes to high-rise buildings, a crane is required.

By the way!
Materials that have retained their performance can be reused. To do this, care should be taken when dismantling and transporting them.

Features of dismantling certain types of coatings

Modern roofs are most often made of metal tiles, ceramic tiles and slate. But in old houses you can find completely different materials, each of which has its own characteristics when carrying out work.

  • Ceramic tiles can be removed from the bottom up.
  • The metal roof is removed sequentially, starting from areas near walls, pipes and other protruding places.
  • It is more expedient to remove wave slate in the reverse order, from top to bottom.
  • The bituminous roof is removed using special equipment.
  • Soft or roll roofing is cut into pieces and gently goes down.
  • The analysis of an ordinary covering begins with the disclosure of one fold, then with the help of tools, parts of the shelter are lifted in a row and turned over to a nearby row. After disconnection, they are lowered to the attic floor.
