Asphalt shingle roofs are one of the most common and affordable roofing options for homeowners. The lifespan of a shingle roof can vary based on the quality of the shingles, the climate, the roof's exposure to the elements, and the proper installation and maintenance of the roof.
High-quality asphalt shingles can last up to 30 years with proper care, while lower-quality shingles may only last 15-20 years.
