What is the recommended lifespan for asphalt shingles?

The recommended lifespan for asphalt shingles is generally between 15 to 30 years, with variations depending on factors such as the quality of the shingles and the climate in which they are installed. Higher-quality asphalt shingles, often called architectural or dimensional shingles, can last longer due to their thicker construction and better resistance to weather-related damage. Additionally, geographical location plays a significant role; in regions with extreme weather conditions, such as heavy winds, hail, or intense heat, the lifespan may be shortened.

Understanding these variables is crucial for homeowners and professionals in the roofing industry when making recommendations for roofing materials. Thus, the range provided reflects a balanced understanding of these influencing factors, making this the correct answer.
