The answer to 'how long do asphalt shingles last' is that asphalt shingles typically last 15-30 years, depending on factors like climate, roof slope, and installation quality. Asphalt shingles are a popular and affordable roofing material for many homes, but they do eventually wear down over time due to exposure to the elements.
Most asphalt shingle roofs will last around 20-25 years with proper maintenance and care. Factors like intense sunlight, high winds, and harsh winters can shorten the lifespan, while a well-ventilated attic and regular inspections can help extend the life of an asphalt roof. Replacing worn or damaged shingles promptly is also key to maintaining the roof's integrity.
