[0002] Flat roofs and sloped roof drainage are commonly used for building roofs and drainage in cold and extremely cold regions. For flat roofs, the drainage slope is generally 3%, which provides good airtightness and thermal insulation. However, it is unable to quickly and effectively remove snow and melted snow from the roof, which can easily cause excessive snow loads on the building roofs. The accumulated water can make it difficult to waterproof the roof, posing a safety hazard to the building.
