The answer to 'how long does asphalt shingles last' is that asphalt shingles typically last 15-30 years, depending on the quality of the shingles and the climate conditions. Asphalt shingles are one of the most common and cost-effective roofing materials used on homes in the United States. They are made from a fiberglass or organic mat base coated with asphalt and mineral granules.
The lifespan of asphalt shingles can vary based on factors like the roof's exposure to the sun, wind, and weather, as well as the quality of the installation. Shingles in hotter, sunnier climates may have a shorter lifespan of 15-20 years, while those in milder climates can last 20-30 years. Proper maintenance, such as clearing debris and inspecting for damage, can also extend the life of asphalt shingles.
