Durability is another strong selling point. While traditional wood shingles may have a lifespan of 20 to 30 years, top-quality asphalt shingles can last 25 years or longer with proper maintenance.

The weathered wood finish further enhances their resistance to UV rays, preventing the colors from fading over time.
