Roofing membrane is a kind of waterproof material used for building roofs, usually made of high-molecular polymers or asphalt and other materials. It has good water resistance, weather resistance and durability, and can effectively prevent rainwater, snow, etc. from invading the interior of the building, and protect the structure and internal facilities of the building.

According to the search results, the types of roof waterproof coils include but are not limited to:

1. EPDM roofing membrane: It is a synthetic rubber with excellent weather resistance and chemical resistance, which is widely used in various types of roof waterproofing.

Two. Polyvinyl chloride (PVC) waterproof coil: PVC material has good aging resistance and corrosion resistance, and is suitable for roof waterproofing in various climatic conditions.

3. Modified asphalt waterproof coil: This coil is usually based on asphalt, and its performance is improved by adding modifiers. It is suitable for various complex roof structures.

Four. Metal roofing system: Metal roofing system is usually made of steel plate, aluminum plate and other metal materials, with good durability and wind resistance, suitable for industrial buildings and large public buildings.

The construction methods of roof waterproof coils include full bonding method, hot melt method, cold bonding method, etc. During construction, it should be ensured that the coil and the base are firmly bonded to form a continuous and closed waterproof layer.

In addition, roof waterproof coils can also be used with other waterproof materials such as waterproof paints and sealing materials to enhance the waterproof effect and adapt to complex waterproof requirements.
