Dismantling of the roll roof, methods, features and process steps, which affects the cost of the roof disassembly

Sooner or later, every owner of a building with a similar roofing coating has to deal with the dismantling of roll roofing. The article describes the situations in which work is carried out to disassemble the roof; lists the features, methods and conditions of work. You will get acquainted with the stages of dismantling and find out what the cost of services for the dismantling of roofing depends.

When dismantling is needed

Utilization of roof material is a multistage process. A quality dismantling (which implies the complete removal of the old roofing pie) is crucial for how reliable and efficient the new design will be. Dismantling the old roofing start in the following situations:

• When a local or overhaul . The materials constituting the roofing pie are designed for a certain service life, determined by both technological parameters and operating conditions. After the expiration of the construction begins to fall into disrepair, there are leaks. The cause of the repair can be either serious damage (fire, break, rotting of sawn timber) or miscalculations during installation (inconsistency between the sheathing and the truss system and the type of roof). If it is impossible to restore the coating, the worn out roof is replaced with a new one.

• If the owners want to change the appearance of the house by changing the entire roof structure or replacing the flooring.

• During the demolition of the building . Sometimes dense building does not allow to resort to the use of heavy equipment (and, especially, to explosive works) for the demolition of a dilapidated building. In this case, it is dismantled in stages, starting with the roof. Disassembly is carried out manually or by mechanical means.

Features and Methods for Dismantling a Roll Roof

When disassembling a pitched roof, you should avoid dangerous shedding of the roofing material and the collapse of roof elements . Rolled roofing materials, most often used on flat structures, have some special features. For several years, the heat of the sun turns a similar roofing cake into a monolithic mass, tightly connected to the base. Dismantling a soft roof on a flat roof has its own characteristics and is performed in one of two ways:

• Using the wall chaser . This method is suitable if the thickness of the roofing carpet does not exceed 3 cm. The electric tool allows you to cut technical strokes (grooves, grooves) in the old coating. Grooves are cut parallel to each other at predetermined intervals, the resulting fragments of material are separated from the base by hand.

• With the use of a roof ax (cutting into squares). If the thickness of the old coating is more than 3 cm, or if there is no tool at hand, a special ax on a long handle comes to the rescue, with which the pieces of the roof are cut down, and the intermediate parts are peeled off.

Such dismantling works seem simple, but nevertheless require experience, skill and accuracy, and are carried out taking into account the following provisions:

• For high-quality disassembly of the roof of soft coatings, it is important to correctly choose the method of work , and for this it is important to assess the overall condition of the structure.

• The most practical is complete disassembly of a roll roofing . Although there is a way to cover old layers with new ones, it is not suitable for all occasions.

• Repair should be complex , a new roll coating is installed as soon as possible so that atmospheric humidity and precipitation provoke damage to the structure.

Dismantling conditions

Technically competent dismantling of the roll roofing should be carried out under the following conditions:

• Temperature condition . To work on the removal of the old roofing cake is to choose dry, moderately warm weather. If the mark of the thermometer exceeds 20 ° C, the bitumen included in the material begins to soften and the process takes more time and labor.

• Required tools . In order for the dismantling of the roof covering to be done quickly and accurately, it is necessary that the brigade has modern, professional tools and equipment.

• Skilled workers .The team of visiting workers or students united for the season is unlikely to know exactly how the roof was made, and therefore they will not be able to disassemble it correctly and in an optimal way. Hiring non-professionals is fraught with, at a minimum, delaying the deadlines for performing work (sometimes two or three times).

Stages of dismantling the roof

The replacement of the coating is carried out in the following sequence:

• Preparation working site . Before starting work, electrical cables and communication antennas, lightning protection, communication line devices, ventilation pipes are dismantled. It is necessary to inspect the chimneys and dismantle the drainage system.

• Preparation of the attic room (in case of repair of the pitched roof). In places where subsidence of rafters is detected, props and girders are installed.

• Dismantling of roofing . In specialized construction organizations, at least two roofers are engaged in demolition work. If it is intended to dismantle the truss system, they are helped by carpenters and scaffold workers, whose task is to safely descend lumber to the ground. Roofing material is cut into strips, which are then peeled off from the base.

• Disposal of construction waste . Separated rolls are folded and placed in containers.

Often, new rolled material is laid over the old one. This decision seems reasonable because it allows you to speed up the process and shrink the budget as much as possible. However, the method has obvious drawbacks, and savings in the future result in additional expenses. The coating becomes too complex and unnecessarily multi-layered.

When leaks appear in such a cake, moisture remains between the layers and causes accelerated destruction of the roof, and the dismantling of the thick roof will require additional costs. Therefore, it is much more practical to change the roll coating completely in the case of capital repairs. If the owners nevertheless decided to lay a new layer without removing the old one, the work is carried out in the following way:

• The surface is cleaned of dirt and dried .

• If there are defects (bubbles) on the old surface, then they eliminate - they are cut, dried and glued with mastic.

• Laying the roll roofing starts from the bottom of the slope , parallel to the eaves line.

What influences the cost of dismantling services

The cost of disassembling the roof is formed after the inspection of the object; its value is always individual and is determined by the following factors:

• The scope of work and the period of their implementation . Urgent dismantling will cost more, as it will have to attract more craftsmen.

• By the area of ​​the roof and the peculiarities of its construction . The larger the area, the lower the rates.

• Number of coil layers . To remove multiple layers, it takes more time and labor costs increase.

• Features of dismantling . The price is affected by the need to install scaffolding, dismantle ventilation systems or chimneys.

• Additional expenses . The cost may separately include the repair of the foundation, the materials used, the use of special equipment.

• The need for waste disposal . The company can provide transportation and take on the job of lowering the garbage down, its layout and loading it into the car.

Dismantling costs

The cost of high-quality dismantling may seem unnecessarily high, but it is determined by the complexity and complexity of the work. If you have to overhaul the roof, the most practical solution would be to entrust all the work of one specialized organization. Comprehensive repairs performed by experienced roofers will be cheaper and will be carried out promptly. Before the start of dismantling, preparatory work is carried out:

• The employee goes to the object and inspects the roof, assesses its technical parameters and the complexity of forthcoming works .

• On the basis of the received data , the scope of work, the time for implementation and the cost are determined.

• The budget and terms are coordinated with the customer , after which roofers start to work.

The average cost of dismantling services in Moscow and the region fits into the following figures (for 1 m ² ):

• Dismantling works (roof of a residential house or garage): from 85-100 rub. Simple roll roof: from 90-100 rubles. (2 layers of deposited material with a thickness of not more than 6 cm), complex - from 120-140 rubles.

• Complete disassembly (including screed, hydro and thermal insulation): from 170 rub.

• Dismantling the old insulation (mineral wool, expanded clay): from 90-100 rubles.

• Transfer of construction waste : from 1400-1500 rub. / ton.

• Loading of garbage in a container and removal of : from 2500 rub. / ton.

Conclusion

In order to prolong the life of the renewed roll roofing, it will be useful to monitor the surface condition and periodically cover it with a protective compound. It is selected based on the intensity of solar radiation, the type of material and the slope of the roof. In order for preventive measures to bring maximum benefit, they are carried out in dry, warm and calm weather after cleaning the surface and repairing minor damage. If damage takes up to 30-40% of the surface, local repair is necessary. If the damage area is larger, the repair will be useless; a complete replacement of the roof with the dismantling of the dilapidated material.
