Asphalt shingles are also called fiberglass tiles, linoleum tiles, and fiberglass asphalt shingles. Asphalt shingles are a new type of high-tech waterproof building material and a new type of roofing material used in building roof waterproofing.
Beginning in the late 1990s, Shanghai, Dalian and other places in China started a “flat-to-slope” craze. Almost all flat roofs along the streets were changed to sloped roofs, giving the city a completely new look. Asphalt shingles are the main sloping roof material. Their biggest features are light weight and many colors. Asphalt shingles are tile-shaped roof waterproofing sheets made of glass fiber felt as a matrix. After being dip-coated with high-quality petroleum asphalt, one side is covered with colored mineral granules, and the other side is sprinkled with isolation materials. It has good waterproof and It has rich decorative functions and colors, diverse forms, light weight and fine surface, and easy construction.
Asphalt shingles are a decorative and waterproof roofing material. It is produced and used in large quantities in the United States and Canada, and is mainly used for sloping roofs of residential buildings and commercial buildings. Asphalt shingles are also produced and used in Europe, but in relatively small quantities.
In the mid-1980s, Tianjin and Wuhan introduced multi-functional modified asphalt membrane production lines, which can also produce asphalt shingles, but the market has not been expanded. At the end of the 20th century, Shanghai and other coastal cities promoted "flat to slope", and colored asphalt tiles became the preferred roofing material. This not only changes the urban landscape, but also improves the drainage and thermal insulation properties of the roof.
Asphalt shingle construction guide
Many people buy asphalt tiles because they don’t know the construction method, so the construction team can only work on the side and can’t understand it during the construction; there are also many people who want to make their roofs look brand new after buying asphalt tiles, but they don’t know the construction method. The method seems weak; there are still many people who want to replace their roofs with asphalt shingles but are secretly worried about the expensive construction costs. In fact, as long as you find the right method, you can put asphalt shingles on your house by yourself. So what is the specific process?
1. In order to ensure that the product is laid neatly and meets the requirements, the line should be stretched on the layer to be laid before laying. The vertical center line is perpendicular to the ridge and is in the center of the roof. The distance between each line in the vertical direction is three The vertical piece type is 167mm, and the four vertical piece type is 125mm. Each horizontal line should be bounced at a distance of 333mm from the cornice. The interval between other horizontal elastic lines is 142mm. During actual construction, a small amount of adjustment can be made, but the spacing cannot be greater than 142mm. The top of each asphalt tile must be consistent with the horizontal line that is bounced. consistent.
2. Before each layer of asphalt tiles is laid, the initial layer must be laid (a cornice drip board should be installed at the cornice). The initial layer of tiles is cut from asphalt tiles with the tile skirt removed. The initial layer is laid directly along the bottom of the roof slope, with the adhesive side facing up and toward the eaves. Apply asphalt glue to the surface separated from the roof, and use the roof Nails fixed to the roof.
3. At the hidden corners formed by roof gables, parapets and chimneys protruding from the roof, before paving asphalt tiles, waterproof membranes need to be laid on both sides of the hidden corners, with a width of not less than 250mm on each side. The gable walls are flooded. The ends of the colored asphalt felt tiles are fixed with metal batten nails, and the top of the batten is sealed with sealing material.
4. For gutter waterproofing, a layer of modified asphalt waterproofing membrane with a width of more than 800mm should first be laid in the gutter, and then asphalt tiles should be laid on this basis.
5. For the connection between the roof and the vertical wall, step flashing can also be used. At the junction of the two sides, metal flashing with a side length of 200mm×200mm bent into a right angle is first installed, and 100mm is overlapped and fixed on the initial layer of asphalt tiles on the roof. , another 100mm is laid on the wall, and then the first layer of asphalt tiles is laid outside to cover the entire roof part, and then the second layer of metal flashing and the second layer of asphalt tiles are laid, and so on, on the vertical wall Then extend one side 200mm long and 500mm wide into the wall and seal it with asphalt glue or cement mortar.
6. Asphalt tile roof construction should be carried out at a temperature above 5°C. Construction is not allowed when winds are above Level 4 and on rainy and snowy days. Construction workers should wear rubber-soled shoes during construction and try to avoid stepping on asphalt tiles directly. If necessary, temporary paving can be used Protective layer to avoid tarnishing or stepping on the laid tile surface.
