Dismantling process technology

This is a rather complex and responsible job, so you can’t do without a preparatory stage. First you need to remove all wires and pipes located on the surface of the roofing. You should also get rid of all decorative elements, if any.

Important! If the roof is of the attic type, then you must start by dismantling the attic windows.

Now you definitely need to prepare the tools necessary for the dismantling process, and you should also take care of having insurance. For accurate and reliable removal of materials from the roof, professionals recommend using a block transport system. It is inexpensive, but thanks to it, it is possible to reduce the amount of waste.

Removing a soft or metal roof

The tools you will need are a special ax and a stock cutter. Every roofing specialist must have such devices.

Please note that bitumen can become very soft in the heat, so you should not dismantle a roof made of soft materials at too high temperatures. Ideally, the day for such work should be dry and windless. A roof made of roofing felt or other soft material is chopped with axes and then rolled into windrows. This type of roofing cannot be reused. The waterproofing should be disconnected carefully and with the expectation of its further use.

Dismantling of a roof made of profiled materials begins from those places where the covering is adjacent to chimneys or other structural elements. Then remove the ridge and get rid of the wind slats. It is better to disconnect the roofing sheets themselves in order from top to bottom. After completely removing the sheet materials, you can move on to the gutters. If they are removed correctly and carefully, they can be reused. Then all that remains is to get rid of the metal profile.

When dismantling, you will need a thorough approach with serious tools. Source en.decorexpro.com

In order to disassemble a wooden frame, you can use a crowbar, hammer, chainsaw and hacksaw. It is better to remove all supporting structures by working from the inside of the roof. It is possible to use platforms and scaffolding. This completes the dismantling of the old roof with a soft or metal covering.

On our website you can find contacts of construction companies that offer the service of completing the construction of unfinished turnkey houses. You can communicate directly with representatives by visiting the “Low-Rise Country” exhibition of houses.

Removing slate or seam roofing

This procedure differs significantly in the technology of work from that described above. To begin with, it is worth noting that the slate roof is the most common in Russia. That is why most often work is carried out to dismantle this particular coating. Any craftsman can disassemble this type of roofing in a few hours, because even novice roofers always have extensive experience working with slate roofs.

Tools include a chisel, a crowbar, a roofing hammer, and a chainsaw for dismantling wooden parts.

To dismantle the roof, you must first remove the ridge. This is followed by the removal of nails, followed by the removal of slate sheets from the seats. Building materials are carefully separated and stacked. It is worth noting that the prices for dismantling slate roofs are low.

Video description

You can learn more about dismantling slate coverings in an easy way and without losing material by watching this video. A professional will tell you about the specifics of the work and give useful advice:

When working with seam roofing, the first step is to disconnect areas or sheets adjacent to projections, such as pipes. Also, if there are dormers, awnings or gutters, the materials around them need to be removed first. On roofs with a boundary grille, the roofing covering should only be dismantled above it. The rest is removed from the attic.

Prices for roof dismantling

Let's figure out how much it costs to dismantle the roof. There are a huge number of names of works and types of roofing in the catalogs. Their prices vary and are based on the complexity of the procedures. Therefore, before ordering a roof disassembly, you should familiarize yourself with all the price offers in your city. Specialists will take measurements, assess the complexity of the structure, and, based on the area and type of roof, calculate the cost of the work. Prices will be indicated for Moscow and the Moscow region.

So, when dismantling the roof, the price per m2 will be within 100 rubles. This includes slate, corrugated board, ondulin and other coatings.

Regardless of the type of roof covering, the price for dismantling will be approximately the same Source byn.lonavuxe.ru.net

The same price (100 rubles per m2) was established for work on cleaning the insulation.

For the same 100 rubles you can order the dismantling of a square meter of sheathing. These works are not particularly complex and do not require great roofing skills. That is why their prices are lower than for other works.

Dismantling a continuous roof covering will cost 150 rubles per m2. For the same price, specialists will carry out procedures for cleaning the soft roof.

The situation is different with the work of dismantling roof windows. The price is per square meter - on average 850 rubles, and per piece - about 1,500 rubles for one window. Such work is highly complex and requires experience. Therefore, the price for them is higher than for other events.

A mansard roof with windows will cost more Source salonbuduar.ru

Please note that the company may raise the price due to the high complexity of the procedures. For example, dismantling a roof with very steep slopes will cost more than dismantling a flat roof of the same area.

Conclusion

Dismantling work must be carried out competently and carefully, as well as saving materials. Don’t forget about safety, because the old building should not collapse on people or pets. That is why it is better to entrust the dismantling of the roof to professionals.

Demolition (partial or complete dismantling and demolition of buildings) is increasingly emerging as an independent branch of construction. As in every type of activity of a narrow focus, established technologies and rules have developed here. Dismantling experts with extensive experience and professional equipment are superior to beginners in labor productivity and deadlines for completing the amount of work. But when it comes to the private housing construction sector, property owners prefer to disassemble their houses themselves. It saves money and is partly even interesting. To help those who find themselves in such a situation, we will outline the practical nuances of dismantling the roof.

When to dismantle the roof

Roof demolition is a complex technological process, accompanied by the disposal of roof material and requiring considerable financial investments. The decision to dismantle is made on the basis of engineering analysis and is carried out in the following circumstances.

The difficulty in carrying out dismantling work on the roof is due to a number of factors:

• it is possible that the remains of the roof may fall from a height (chaotic shedding must be avoided);
• dismantling rotten trusses is fraught with collapses, which need to be properly controlled;
• carrying out partial repairs should not entail destruction of the remaining roof elements.

The regulatory document regulating the procedure for dismantling buildings and structures subject to demolition is the Code of Rules SP ХХХ.1325800.2016, approved by the Ministry of Construction and Housing and Communal Services of the Russian Federation. Clause 6.8 “Dismantling of roofs” describes the stages of roof dismantling:

1. Removal of roof covering.
2. Dismantling roof support structures (slabs, rafters or decks).
3. Dismantling of adjacent structures - cornices, parapets, pipes, floor slabs, etc.

The dimensions of the strips into which soft, rolled and mastic coatings are cut are specified. It is recommended to maintain a size within the range of 1000x500 mm, which is the most convenient for storage and transportation during disassembly.

Stages of roof dismantling

Before starting the actual dismantling of the roof, you need to prepare the work site:

• remove all unnecessary objects that interfere with dismantling;
• remove billboards and banners if present;
• prepare communication antennas, electrical cables, ventilation pipes, lightning protection, etc. for disassembly;
• inspect and assess the degree of emergency of chimneys;
• install purlins and supports in the attic in places where the rafters sag (for pitched roofs);
• in mansard roofs, prepare for window removal.

Among other things, it is necessary to think through convenient ways to lift and lower workers from the roof to the ground and ways to dispose of construction waste and dismantled roofing.

Required tools:

• long, strong stairs reaching to roof level;

  A mobile ladder made of lightweight aluminum with the ability to be attached to the ridge greatly facilitates the work of installers when dismantling the roof

• ladders for roofing work with a hook at the top;

  The hook at the upper end of the ladder is securely fixed in the desired position, so such a ladder will reliably hold the person on it on any roof

• pry bar, crowbar, hammer, ax with a long handle and a wide blade, hand or electric saw;
• screwdriver or drill with a set of attachments;

  A battery-powered screwdriver is more suitable for working on the roof.

• safety ropes.

  All work at height must be carried out only with reliable insurance

If conditions do not allow the use of special lifting equipment (crane, garbage collection channel with a tank or container, etc.), a block system is installed to lower the dismantled units. If power is available, use an electrically driven winch with a rated load capacity of at least 0.8 tons. Strong roof elements are used for fastening; the boom reach must be at least one meter.

It is convenient to use a stationary winch to lift and lower construction loads when dismantling the roof.

Dismantling of electrical equipment

Electrical equipment includes all remote elements of engineering systems located on the roof surface - antennas, air conditioners, lightning protection receivers, lighting fixtures, etc. Dismantling is carried out only after complete de-energization of the equipment and internal communications of the house. In private houses, the “earth” of the electrical network is connected to a common ground loop, to which lightning protection is connected. Therefore, in order to avoid injury from stray currents, it is recommended to disconnect the ground terminal from the current collector bus. To ensure safety, a sign “Do not turn on, work in progress” is installed on the switchboard. All preparations should be carried out in dry, windless weather.

Dismantling chimney pipes

The brick pipe is dismantled from top to bottom. The hole is covered with a rag. The masonry is hammered away using a mason's hammer, crowbar or pry bar. Having brought the disassembly to the plane of the slope, another row is removed, at which point the preparation for removing the roof ends. Asbestos and metal pipes are usually attached inside the attic, so the disconnection occurs at the bottom. If the pipe has a large diameter and weight, it can be cut into pieces. Of course, provided that the roof is completely dismantled and the pipe is subsequently replaced with a new one.

Dismantling the chimney pipe is greatly facilitated if the chimney is laid on the outside of the building

Removing additional elements

Additional roof elements include:

Most often, extensions are made from sheet metal coated with a polymer composition. They are fastened with self-tapping screws or roofing nails. Dismantling is done using a nail puller or screwdriver. The drip rails are disconnected after removing the first row of roofing and gutter from the eaves. Soffits are removed from stairs. If the accessories are in working order, they can be reused.

Step-by-step removal of roofing material

The algorithm for dismantling different roofing coverings is different. The general rule is that dismantling is carried out in the opposite direction to installation. If it is, for example, slate that is laid from the cornice to the ridge, then disassembly begins from the ridge and ends with the cornice. However, there are exceptions. The metal seam roof can be dismantled from any place if necessary. Having made a transverse cut in the sheet, disassembly continues in any direction.

The types of dismantling of various roofing materials will be discussed in more detail in a separate section below.

Dismantling thermal insulation and waterproofing

After removing the outer layer of roofing material, they begin layer-by-layer removal of the elements of the roofing pie. The waterproofing is wound into rolls and lowered to the ground. Then the insulation mats are removed and, finally, the vapor barrier film is removed. If the materials have not been damaged during operation, they are stored under a canopy so that precipitation does not wet the mineral wool. Roofing felt is rolled into rolls and stored in a vertical position without kinks. The vapor barrier membrane is folded like a tablecloth and left in a dry, ventilated place. Sometimes it is more convenient to dismantle the roofing pie from the inside of the pitched roof. In this case, the materials are stored inside the attic.

The roofing pie most often has a standard structure, and its disassembly is done in the reverse order

Dismantling the sheathing and rafter system

If significant damage is detected (including fungus, mold or rot), the roof truss system must be dismantled. This can be either complete or partial disassembly and subsequent replacement of the trusses. During complete disassembly, dismantling begins with the removal of the sheathing and ridge girder. Then the bolts and ties are disconnected. The rafter legs are carefully lowered as they are released. If subsequent restoration and reuse are intended, each part is pre-numbered by applying a serial number with paint.

Special scaffolding is installed inside the attic to make it convenient to tear off the sheathing boards along the entire height of the roof

Work is being carried out from the attic.

Features of dismantling different types of roofing

Let's take a closer look at the nuances of dismantling various types of roofing.

Dismantling of roll roofing

Dismantling a roof covered with rolled materials is a labor-intensive and, accordingly, expensive process. In summer, when the temperature in the sun reaches 40 degrees or more, the bitumen layers are sintered into a single monolithic layer. This “carpet” sticks tightly to the base, so removing it can be very problematic. In practice, two methods are used:

Video: roof cutter

The drive of the rotation mechanism can be electric or autonomous (based on a gasoline engine). The latter, as a rule, develops more power.

To dismantle roll roofing, it is better to choose windless and not very hot days. Under the influence of high temperatures, bitumen begins to melt, and this greatly interferes with work. The best air temperature is about 20 o C.

Removing a slate roof

The optimal number of installers for removing slate coverings is a team of three people. You can work together, but the speed will drop sharply. It is strictly prohibited to dismantle a slate roof alone.

Video: dismantling slate

The sequence for removing metal strips is as follows:

Typically, disassembly is carried out by progressively moving in a horizontal direction from the left edge of the ramp to the right. Gutters, eaves strips and soffits are removed from the attic. If the roofing material is intended to be used in the future, a screwdriver is used to open the seam joint. If there is no need to preserve the sheets, the lying seams are cut with a roofing chisel.

Video: dismantling a seam roof

Dismantling a roof made of corrugated sheets

To dismantle a corrugated roof, a team of at least three installers is needed. The separated sheets are passed “on a relay race” from hand to hand until they reach the ground. Dismantling begins with vertically located elements of the lining of pipes, chimneys, and other adjacent structures. After that:

1. The wind strips, valleys and ridge are removed.
2. The top roofing sheets are detached and lowered to the ground.
3. All other rows of profiled metal sheets are removed.
4. Drips, drainage channels and cornice strips are dismantled.

A team of three people can ensure coordinated work on dismantling corrugated sheets

Metal tiles are installed in the same order as slate - from bottom to top. Consequently, dismantling is carried out in the opposite direction.

In conclusion, I would like to once again draw attention to the fact that work at height, which includes the dismantling of roof coverings, is equal in level of danger to mining and drilling and blasting. Compliance with safety precautions is the first thing you need to remember when starting work. Take care of your life and health. Don't neglect safety precautions. Use safety ropes, construction helmets and other safety equipment.

– dangerous and labor-intensive, and not only because they are performed at height. For safety reasons, to eliminate the risk of injury to people and collapse of the structure, we strongly recommend that you involve in this work, and the information provided is for informational purposes only!

Features of dismantling work

The dismantling of the roof is carried out during a major, partial repair when replacing the old covering with a new one. There are many reasons for this - wear or damage to the coating, redevelopment, addition of an attic, etc. Also, the dismantling of the roof is carried out during the demolition of the entire building.

In some cases, you may not have to resort to dismantling the entire roof: it is enough to replace the outer material, but only if the strength of the existing rafters is recalculated and the load that the new roof will create is assessed. But if we are talking about redevelopment, completion of a new floor or part of the building, as well as wear and tear of the roof, dismantling is indispensable: all 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 the materials, the number of storeys of the structure, the roof area and a number of other features. An assessment of the condition of the roof is always carried out on site - if the roof is old and in disrepair, additional safety measures will be required. The site must be isolated to prevent third parties from accessing the work site.

Algorithm for performing 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, but in other cases this is excluded.

Attention!
Safety 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 shoes, personal protective equipment for hands, head and respiratory organs is required (a lot of dust is generated during the work)

Approximate work plan:

• Removal of cladding, which is carried out taking into account the characteristics of the coating.
• Removing the sheathing and removing the insulating layers. Work is carried out in turns, depending on the condition of the roof and materials. The sheathing is removed very carefully and carefully so that not a single element remains. The insulating layers are also dismantled one by one.
• Analysis of the rafter system. The additional beams are removed first, and the supporting beams are removed last. The connecting elements are carefully cut with a saw.
• Removing insulation.
• Sorting of materials and removal of construction waste.

When dismantling the roof of private houses, 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 a must.

By the way!
Materials that have retained their performance qualities 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, 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 are removed from bottom to top.
• The metal roof is removed sequentially, starting with areas near walls, pipes and other protruding places.
• It is more advisable to remove wave slate in the reverse order, from top to bottom.
• Bituminous roofing is removed using special equipment.
• Soft or rolled roofing is cut into pieces and carefully lowered down.
• The dismantling of the row covering begins with the opening of one fold, then with the help of tools they lift up parts of the cover in a row and turn them over onto the adjacent row. After disconnection, they are lowered into the attic floor.

At first glance, dismantling a slate roof, a roof made of corrugated sheets or metal tiles can be classified as a 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 new roof installation depends entirely on the professional level of the roof dismantling. Failure to comply with technology when carrying out dismantling work can be fraught with the most undesirable consequences, ranging from damage to the rafter system due to improper work, ending with partial destruction of the roof. This only means that such a task should be performed only by professionals who know and take into account a variety of nuances that are inaccessible to the average person, and who own the appropriate equipment.

Prices for roof removal

Dismantling of soft roofing. Stages of work

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

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

The price also includes removal of generated construction waste.
When replacing a roofing covering with a covering of a different type, all stages must be carried out. With partial repairs, only some of them can be performed. When performing partial dismantling of the roof, prices will be formed according to:

• the volume of upcoming work,
• labor intensity of the process,
• quality and urgency of services.
