Roofs of shingles – one of the most versatile solutions for any type of country house. This coating has not only a number of undeniable aesthetic benefits, but also high reliability. Being properly installed, it will last for decades, preserving its original attractiveness. Below we explain how to install a roof with shingles.
Your roof will last a long time
In recent years, production technology of shingles has made great advances. Today this material can boast a long service life, and the warranty on some of its varieties up to 55 years. This is possible because the industry leaders have learned how to set the necessary characteristics of shingles.
For example, it was found that even a small amount of polymer added to the bitumen, raising the quality of the material to the level of the used modifier. In particular, the addition of copolymers reduces the brittleness temperature by 30-40%, and the use of atactic polypropylene provides protection against ultraviolet radiation UV and thermal aging. As a result, for example, TEGOLA flexible shingles based on polymer bitumen can not only withstand temperatures from -70 ° C to +140 ° C, but also practically unaffected by UV.
However, the advantages of any material is disclosed only if properly installed. When it comes to the roof, its durability depends not only on the quality of the materials themselves, but no less on how the installation of roof structures in general.
What you should know about under-roof ventilation
Its proper operation – one of the most important conditions for longevity, so you need to pay due attention to ventilation. Under the solid base must be formed a single ventilation chamber, which provides unhindered and continuous circulation of air from the eaves to the roof ridge. Under-roof ventilation helps to solve many problems: in winter to avoid ice and icicles in the summer – to reduce the temperature in the attic.
“Effectively organized underlay ventilation – this includes the protection of trusses, insulation and the roof. Correctly calculate the gaps and traction “by eye” is difficult, so it is better to have made a preliminary expert draft of the roof,
– Says Sergey Ershov, an engineer from TEGOLA, one of the world’s leading manufacturers of roofing and waterproofing materials.
How to mount a solid base
Flexible shingles, as we know, should be installed on a solid base with underlay mat. For this purpose the most often used waterproof OSB boards with thickness of 9 mm, which are recommended to be fixed to the counter-batten with self-drilling screws or nails with dent. As for the underlay mat, it is laid on the substrate with self-adhesive rolls or nailed with a slight overlap. It is important that the nails that fasten solid base have a length of 2.5 times the thickness of the plate.
“In addition, any wooden board reacts to moisture, so it can change size,
– Sergey Ershov. –
To compensate for linear deformations of the boards should be mounted with an offset vertical joints “in a row”, leaving between them three-four-millimeter gap.
What to look for when installing flexible shingles
Installation of shingles is simple and virtually no waste. But you should pay attention to some features of the technology. For example, when laying overlaps shingles overlap each other. That is why each next row must be installed in the proper places the nailing axis is in the central part of the shingles and simultaneously fix the upper edge of the lower row. And when laying the cover on slopes with a slope of 60 ° or more, the upper corners of the shingles are mounted two additional nails. Through the observance of this simple rule, the roof will be equally reliable and in windy and rainy weather.
The nails themselves must meet certain requirements.
“Use a roof, galvanized, “ruffled” with a hat diameter of at least 9 mm,
– emphasizes Sergey Ershov. –
special attention should be paid to the installation of tiles in the valley. Here to ensure sealing fasteners at a distance of 30 cm or less on both sides of the valley axis is made only with the help of mastic “.
If the installation takes place at temperatures below 10°C, the additional thermo-adhesive system of the shingles, namely bituminous adhesive strips/dots and self-adhesive surfaces, has to be pre-heated with a construction dryer. And after work is complete you need to make sure that the tight fitting lugs shingles and, if necessary, further glue them with bitumen mastic. In cold weather, shingles should be kept in a warm room for at least a day, and on the roof to submit in small batches.
Additional materials: what you need to know
In addition to the shingles for installation of flexible roof will require some additional materials:
– Continuous base – damp-resistant OSB 3-board
– underlay roll material
– Cornice and end metal aprons strips
– Bitumen mastic and roofing nails
– Aerators or other ventilation elements
– snow stops.
“Particular attention should be paid to the underlay roll material, which generally consists of a glass or polyester fabric, modified bitumen, the lower layer of adhesive with a protective film and the upper abrasive base,
– explains a professional roofer Anton Skuratov. –
They not only serve as additional waterproofing and sealing the joints between the slopes in the areas of valleys, around the junction of the roof to the walls and pipes and walk-through elements, but also compensate for the irregularities of solid crates. And, depending on the type, can serve as a “temporary roof” if the installation of shingles is not immediately. In particular, the roll-sealed self-adhesive waterproofing material “Silbar” is able to self-compacting, forming a solid monolithic surface”.
Snow Retention
The most popular piece of metal snow detentions that will hold the snow on the roof, preventing it to collapse down the entire mass. Avalanche-like snowfall from the roof can damage the gutter system and roofing, and also poses a danger to humans and property located near the house. Snow stops will also provide protection from mechanical friction of the ice masses on the shingles, which will increase the service life of the roofing material.
“Flexible shingles – durable, aesthetic and high quality material. To use its properties to the fullest extent, you need to carefully follow the manufacturer’s recommendations, follow the instructions for installation and use only qualified professionals with experience”,
