The answer to 'lifespan of shingles' is that most asphalt shingles have an average lifespan of 15-30 years, depending on the climate and quality of the shingles. High-quality architectural shingles can last 25-50 years, while basic 3-tab shingles may only last 12-20 years. Proper installation, ventilation, and maintenance are key factors that affect how long shingles will last on your roof.
Factors like sun exposure, wind, and precipitation can all impact the lifespan of your shingles. Homes in hot, sunny climates will generally see shingles wear out faster than those in more moderate regions. Regular inspections and prompt repairs of any damage or leaks can help maximize the lifespan of your roof.
