How is the dismantling of the old roof - technology and cost
When it comes to disassembling old or broken roofing structures, one recalls a common expression that says that breaking is many times easier than building. In confirmation of this in building encyclopedias and Internet resources, you can find thousands of articles about roofing, and you have to collect information on how to dismantle the roof bit by bit, although this process cannot be called technologically simple. In this article we will describe how to carefully dismantle the pitched or flat roof.
When is the disassembly performed?
Roof dismantling is a technologically and organizationally complex process of removing the old roofing and dismantling the frame. This expensive operation is performed in the following situations:
- During the overhaul of the roof. Even the most reliable roof can not stand forever, so you have to perform a major overhaul of the structure with full replacement of the cover and, if necessary, supporting structures.
- During the demolition of the building. If, due to the density of buildings or the inability to use heavy, massive equipment for the demolition of structures, it is necessary to dismantle the roof with your own hands, gradually dismantling the structure.
Note! Although the cost of high-quality dismantling is high enough, it is better not to take risks and entrust the implementation of this complex and time-consuming task to professional craftsmen. Since the high rates are more than paying off operational work and experience roofers.
Flat roof demolition
It is quite difficult to dismantle rolled roofing materials with the help of which they overlap flat roofs, therefore the cost of their major repairs is high. In 1-2 seasons, under the influence of the sun, they stick together in one thick monolithic layer, which is difficult to separate from the base. Dismantling of the old roof of soft coatings is carried out in the following ways:
- Using the wall chaser. A wall chaser is a special tool that cuts strips in the old roofing to facilitate material removal. This method of dismantling the roof strip is suitable if the thickness of the layer being deposited does not exceed 30 mm.
- With the help of a roofing ax. If the thickness of the soft roof exceeds 3 cm or there is no special tool at the disposal of the master, it’s easier to divide the roofing sheet into squares, which can be separated from the base with a long-handled roof ax.
Important! The high cost of dismantling a soft roof is due to the time and effort spent on separating the roofing material from the base. In addition, the work must be done in dry, but not hot weather, as at a temperature above 20 degrees bitumen, which is part of the roll coatings, melts.
Dismantling pitched roofs
Despite the frighteningly high prices for the dismantling of the roof, the majority of developers carry out this operation, which is necessary for a quality overhaul of the coating, with the help of special companies providing services of professional craftsmen and special equipment. Disassembly of pitched roof structures occurs in the following sequence:
- First, it is necessary to remove all external electrical equipment from the roof, including antennas, and to disassemble chimney pipes.
- Then it is necessary to remove all the additional elements that make up the structure: ridge profiles, frontal and curtain rail strips, spotlights to facilitate the dismantling of the roof covering.
- After that, you can carefully and gradually remove the roofing material, starting from the ridge.
- After removing the roofing material, perform the dismantling of thermal insulation, waterproofing.
- If necessary, after removing the waterproofing coating and thermal insulation, the structural trusses are analyzed.
Many developers, having learned how much it costs to disassemble an old roofing structure, can it be done with their own hands. However, we advise you to turn to professionals, as they will be able to disassemble the roof in a matter of days, and also dispose of the dismantled material.
