1. Quality of Material The longevity of composite shingles is largely determined by the quality of the materials used in their construction. Higher-grade shingles with better resistance to UV rays, moisture, and temperature changes generally have longer lifespans. When choosing shingles, it’s essential to consider the manufacturer’s reputation and the warranty offered. Many reputable brands provide warranties that can extend up to 50 years, which is a good indicator of their expected durability.
