A roofing system is a combination of materials and components designed to protect a building from weather elements. It typically includes layers such as underlayment, insulation, and the outer roofing material, which can be made from options like asphalt shingles, metal, or tiles. Each type of roofing material has its own benefits, such as durability, cost, and aesthetic appeal. Proper installation and maintenance of a roofing system are crucial for its longevity and effectiveness. Factors like climate, building design, and local regulations can influence the choice of roofing materials. Regular inspections can help identify issues early, ensuring the roof remains functional and safe over time.
