Roofing refers to the materials and construction that cover a building and help protect it from rain, wind, sun, and other weather. A roof system may include a visible covering, a supporting structure, waterproofing layers, and details such as flashing that direct water away from joints and openings. Roofs are commonly designed for steep slopes, which shed water by gravity, or low slopes, which rely on carefully managed drainage and waterproofing. Materials vary: shingles are widely used on pitched roofs, while metal can be formed into panels or other profiles. The category includes roofing-related names such as GAF and Monarch Roofing, bringing together references to businesses and products connected with this field.
