The roof of any building is one of the most beautiful, but at the same time “capricious” of its elements, constantly requiring supervision and caring for himself. No matter what time of year stands in the yard – every season carries a potential load for a roofing carpet and, possibly, a danger. Whatever the type and purpose of the structure – in any structure there is an Achilles heel.
In this article, we will highlight the issues of proper operation and care for a soft roof and describe the technology of repairing a waterproofing carpet.
Materials for repairing soft roof
The main material used for the complete or partial reconstruction of the soft roller roof is the bitumen-melted membrane produced from SBS-modified polymers. The method of attaching such material to the roof horizon – gluing. When the flame of the propane burner is heated, at a temperature of about 600 OS, the polymer softens and acquires excellent adhesion to the base. After cooling, the carpet is reliably glued to the floor plate or old roof.
The main condition for the performance of work with the floating materials is a positive air temperature, since most bitumen membranes are glued only in such conditions.
Certain types of bases before a waterproofing sticking requires applying a bitumen primer that increases the base adhesion. This thick, cream -shaped consistency, liquid can be applied to the base of the roller or brush.
Traditional problems of soft roofs
The best repair is the one that is done on time. It is easier to fix small shortcomings and damage to the roof carpet than to raise half the roof in search of leaks. To properly assess the volume of repair measures, it is necessary to carry out a periodic inspection of the roof horizon for traditional damage for a certain type of building.
Depending on the purpose of the building, weaknesses subject to destruction of the membrane may differ.
Residential multi -storey buildings.
Residents of high -rise buildings use a roof to install antennas, and the inhabitants of the upper floors are also to install air conditioning and ventilation systems. On the roofs there are exits to elevator mines, serviced sections of chimneys, plumbing systems, etc. D. For these reasons, service personnel often rise to the roof, as well as utility workers who cleanse the roofs of snow and ice in the winter period.
Unfortunately, none of the above “guests” of flat roofs, as a rule, is burdened with concern for the integrity of the waterproofing carpet on the coating of the building. When examining, it is necessary to pay special attention to the state in which the parapets, the vertical outputs of the waterproofing carpet, the sections around the newly installed equipment, the tracks along which the maintenance personnel is moved, etc. P.
All these areas must be checked for damage and cracks in which moisture may fall and, freezing, cause further destruction of waterproofing and lead to through freezing of the roof.
During the reconstruction of the roof, it is possible to provide for the installation of special cabinets or catwalks for particularly heavy structures (for example, advertising shields), as well as strengthening vertical areas with additional layers of waterproofing material.
Industrial facilities.
The main complexity of industrial buildings (warehouses, production) is in the absence or improper operation of the drainage system (storm sewers) on the roof. Due to the poor or completely absent dliming of water on the roofs in the autumn-spring period, ice forms, which is removed by mechanically, applying irreparable damage to the waterproofing material.
On such roofs, a complete reconstruction of waterproofing is usually performed by laying a new layer of bituminous material over the old, damaged. The second component of the long -term uncindertic service of roofing material is timely briefing on permissible actions on the surface of the bitumen membrane of each employee working on the roof of the building.
Seasonal problems of waterproofing soft roof
In the spring, it is recommended to check the roofing for the presence of air bubbles, the quality of the connection of neighboring paintings, the tightness of the insulation of deflectors and the water intake funnels of the storm sewer.
In the summer heat, special attention should be paid to the formation of microcracks with high -temperature heating of bitumen, the material should be evenly distributed along the horizon and parapets without the formation of places in which an increased surface tension of the membrane appears and there is a risk of cracking it.
In the autumn, it is best to carefully monitor the working germs and timely clean the gutter and funnels from the falling foliage. The best solution here will be the installation of special filters on deflectors and water receivers.
In the winter period of time, if the height of the parapet allows, it is necessary to clean the roof on snow in a timely manner, but not to the coating itself, but leaving 2-4 cm of snow crust-it will not create a decisive load, and the waterproofing coating will avoid the risk of damage to the shovel or scraper.
