Flexible shingles are popular with developers due to their attractive appearance and versatility. However, to achieve a reliable, durable, and watertight roof, it is essential to strictly adhere to the installation procedure and roofing construction technology. Improper execution of any stage of the work will lead to leaks and mold, reducing energy efficiency and the lifespan of the building.
By following the recommendations outlined in the material below, you can extend the service life to 50-60 years and avoid major repairs for a long time.
Two types of soft roofing materials are used in construction: rolls and shingles. For private homes with pitched roofs, the latter is used. A roof finished with bitumen shingles will be not only reliable but also beautiful.
Structurally, this roofing material consists of individual elements called shingles. They are 1 meter long and range in width from 30 to 35 cm. They are made from fiberglass mat impregnated with bitumen mastic. A colored stone chipping is applied on top for a beautiful finish. This also provides additional protection from adverse external influences.
The flexibility of shingles makes them easy to install on roofs with complex shapes, including domes, cones, and bulbous roofs. However, a reliable foundation is required to ensure the roofing can withstand the weight of snow and mechanical stress.
In private construction, single-, double-, and triple-layer shingles are used. The latter option has the best performance properties. The large number of layers and thickness increase the structural reliability.
When choosing this roofing material, keep in mind that the minimum roof pitch should be 12 degrees. Anything less will prevent water from draining quickly enough, preventing proper watertightness.
The house's roof is a complex, multi-layered structure with insulation that improves the building's energy efficiency. The roofing structure consists of the following materials:
Vapor barrier membrane. Prevents insulation from becoming damp due to water vapor generated inside the home due to human activity. It is attached to the inside of the rafters. A special film is used that allows air infiltration and promotes moisture removal from the insulation layer.
Thermal insulation material. Basalt mats are most often used for roofing. They have a low thermal conductivity, protecting rooms from cold in winter and heat in summer. Due to their sound absorption properties, they also act as a soundproofing layer. The insulation is placed between the rafters in a 10 cm layer.
Waterproofing. This is an additional film that protects the insulation from moisture and damage caused by wind in the ventilation gap. It is installed on the outer surface of the rafters before the sheathing is installed.
The base itself for laying flexible shingles also has its own unique characteristics. When installing a roof, it's important to ensure ventilation of the insulation while also creating a continuous surface for adhering the shingles.
During roof construction, battens are installed on the rafters after the waterproofing has been laid. Plywood or OSB boards are attached to these battens, which will serve as the base for the flexible roofing. The minimum thickness of the plywood sheets is 9 mm for single-layer roofing and 12 mm for multi-layer roofing.

Once the rafter system is prepared and the solid sheathing is in place, you can begin installing the roofing. The entire process can be roughly broken down into the following stages:
This step is necessary to ensure a tight seal between the underlayment and the roof base. For reinforcement, special strips made of thin iron sheets can be used. They are installed so that the edge of the strip meets the edge of the OSB or plywood. They are secured with nails driven in a staggered pattern. Individual elements are joined by overlapping each other.
Proper installation of bituminous shingles requires the use of an additional waterproofing layer. Some developers, trying to save money, install waterproofing only on complex roof areas, such as slope joints, ridge caps, and abutments. This is acceptable, but in this case, shingle manufacturers cannot guarantee a completely watertight surface.
Waterproof materials are used as underlayment. They typically have a sticky underside for easy adhesion to the roof. Additional nailing is also provided.
Lay the underlayment starting at the valleys to ensure it's evenly applied to each roof slope. It's recommended to use whole sheets without overlapping. If necessary, overlap by at least 30 cm, and thoroughly coat the joints with bitumen mastic.
This flashing is installed before the shingles are glued down. Its primary purpose is to protect the roofing casing from precipitation and wind. The flashing is attached to the underlayment using roofing nails in a staggered pattern. It's best to seal the joint with mastic to ensure a tight seal.
To ensure even shingle installation, mark the roof vertically and horizontally. Vertical lines can be spaced at intervals equal to the line width. Horizontal lines should be spaced approximately 80 cm apart.
The first row of roofing is made up of special rectangular ridge and eaves tiles. They are glued to the ridge cap 1-2 cm from the roof's eaves edge. The tiles are then secured with nails.
After this, lay the remaining tiles, starting with the bottom row and gradually moving upward. It's important to determine the horizontal direction so that the roofing looks uniform.
At the final stage, valleys, ridges and ribs are formed, and connections to ventilation and chimney pipes are arranged.
