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 conditions. Higher-quality architectural shingles can last up to 50 years with proper installation and maintenance. The lifespan of shingles is influenced by factors like sun exposure, weather, and how well the roof is ventilated.
Most standard 3-tab asphalt shingles have a lifespan of 15-20 years, while premium architectural shingles can last 25-30 years or more. Proper installation, ventilation, and regular maintenance like roof inspections and repairs are key to maximizing the lifespan of your shingles.
