Do-it-yourself flat roofing, as the construction of modern high-rise buildings takes place, involves the construction of flat roofs with a soft waterproofing coating roofs. Melt and rainwater is discharged by the drainage system.
It includes water collection, separation from garbage, fluid intake into the system, removal and delivery of moisture to the general sewage system of the structure.
A flat roof is called relatively conditionally. To collect water that accumulates on the roof, it is necessary to arrange a system that delivers it to the purification and intake points along the valley.
This process is carried out by means of a flat roof slope device. The slope of the roof plane from the parapet to the funnel must be at least 3 0 . Water is collected naturally in a valley with a receiving funnel.
Signs of flat roofs are the materials used for their construction.
It is made by heat brazing bitumen roll materials in several layers. Layout of layers in order from the reinforced concrete slab:
It consists of bitumen deposited materials in rolls. For reliability, the seams of the first layer are covered with a top sheet of waterproofing material.
The principle of its construction is completely opposite to the order of laying layers in the welded roof. Insulation layers are located above the waterproofing layer of the deposited material. For the last layer, a brazed geotextile is used.
For the ballast top layer, gravel or fine crushed stone is used. It is necessary for protection from wind and hail.
This type of building protection is distinguished by the presence of a polymer membrane. It completely replaces the welded soft roof. The priority is that there is no need to use open fire.
It is fastened by means of a mechanical system.
This will allow you to arrange coverage even in frosty conditions. The canvas is monolithic for the entire roof area. The seams are soldered with a special electric iron.
Obtained by modifying the roof with an inversion system.
The ballast layer is replaced with a concrete screed and covered with ceramic tiles. Such roofs are used to organize recreation areas.
Its specialization is the protection of insulating material from the penetration of steam, and its condensation inside the layer of thermal insulation. It works one way. It removes moisture and does not let it through.
The main heaters include:
Polyurethane foam, nanoisol.
Waterproofing material. It is divided according to the method of application and according to the level of location:
The accumulation of water on the surface of any material will inevitably lead to damage. The temperature difference between the material in a dry place and under water leads to the stress of the layers and, in the future, the appearance of a network of microscopic cracks. They will cause ruptures under the influence of ice in winter.
It is necessary to correct the slope in order to extend the life of the waterproofing layer of the roof. It is done in several ways:
The result is the necessary slope for collecting the liquid in the central outlet channel to direct it to the funnel. This method has a lack of high-quality performance due to the large screed laying area. It's hard not to make a mistake.
The layers are then collected according to conventional technology.
Starting from the top layer of insulation, technological changes begin. They consist in the fact that slabs with a bevel along one edge are used. They are made from expanded polystyrene or hard mineral wool. The shape of the slab of each row has a different bevel and organizes the necessary slope of the roof in the overall composition to drain water from the roof.
A layer of waterproofing materials is laid on top.
This method has positive aspects:
For each object, the unleveling device method is selected individually. It all depends on the roof area, budget, and technical need. A roof with proper drainage can only be done once. In the event of a performance error, you will have to incur large expenses.
