The answer to 'how long does shingles last' is that asphalt shingles typically last 15-30 years, depending on the quality of the shingles and the climate. High-quality architectural shingles can last up to 50 years with proper installation and maintenance. The lifespan of shingles is affected by factors like sun exposure, wind, hail, and proper attic ventilation.
Proper roof maintenance, such as regularly inspecting for damage and replacing worn shingles, can help extend the lifespan of your roof. It's generally recommended to have a professional roofing contractor inspect your roof every 5-10 years to ensure it's in good condition and catch any issues early.
