Asphalt shingles are made from natural materials like sand and mineral granules, which are mixed with asphalt or oil to form the final product. The composition of the asphalt mixture varies depending upon the brand and grade of the shingle; some are made with recycled materials as well.
Asphalt shingles come in many different sizes, textures, and colors. They can be installed over wood, concrete or steel decks (or other substrates), but they’re typically installed directly on top of plywood sheathing or OSB (oriented strand board). The protective underlayment boards provide a barrier from moisture penetration into your home’s interior walls and ceilings.

2. How long do Asphalt Roofs last?
Your roof's lifespan is how many years of life you will get out of it. Each type of shingle has a different manufacturer-specified lifespan. A 3-tab shingle will commonly have a 25-year lifespan. Dimensional and luxury-type shingles will have a 30-year lifespan, although the luxury style can possibly be up to 50 years under the correct conditions.
3. Regular maintenance can maximize your asphalt roof.
Regular roof maintenance is important for all types of roofs, but it’s especially important for asphalt shingle roofs. Keeping your roof clean and debris-free will extend the life of your roof and ensure that it stays in good condition for many years.
Asphalt shingles are made from natural materials, and they will deteriorate over time if they get dirty or covered in debris. Debris such as leaves, twigs, and pine needles can break down the asphalt material that makes up your shingles. They also make your roof susceptible to mold growth and leaks caused by water damage.
Regularly cleaning your roof will prevent this from happening by removing any debris that could cause damage to your home or the materials used to build it. It also helps prevent water damage by keeping rainwater away from your home’s foundation.
