WHAT’S AN ASPHALT ROOF SHINGLE MADE OF?
Asphalt itself, also known as bitumen, is a form of petroleum. It’s black and sticky, which is perfect for mixing with other substances as an adhesive material. This material has been used since ancient times mainly for weatherproofing or for patching holes, say in ships. It was also used to embalm mummies in ancient Egypt.
Asphalt shingles have a base of fiberglass, which is composed of cellulose fibers, which itself is derived from recycled waste paper or wood. To make asphalt shingles, the base material of asphalt must be oxidized, which is in essence putting air into this petroleum-based product. Finely ground limestone is usually added in order to make the shingles more durable and more resistant to fire and weather. Meshed into a pulp and formed into sheets, this composite material is then cut into strips and wound onto rolls, which is then cut into shingles.
HOW DO SHINGLES GET THEIR COLOR?
During the manufacturing process, various colored, ceramic-coated mineral granules are added on the surface. These are not just for aesthetics; this top coat protects the shingles from the harmful UV rays of the sun as well as adds another layer of fire protection. These mineral granules are usually small stones. An adhesive that reacts with the sun is applied to the asphalt shingles so when it is heated by the sun after installation, they will adhere better and be more resistant to wind and weather. Finally, the back of the shingles are covered in small particles as well, either sand or mica for the sheer purpose of preventing them from sticking together during transport to your home.
THE POPULARITY OF ASPHALT SHINGLES
As you can see, asphalt shingles have come a long way since the advent of roofs, where mud was simply combined with water. So just why are asphalt shingles so popular?
- Versatility. They come in hundreds of colors, styles, and designs and fit on any roof of any angle or pitch.
- Little maintenance. This is one reason roofs are often overlooked by the homeowner. Asphalt shingle roofs tend to take care of themselves.
- Quick to install. It typically only takes one day to install asphalt shingles.
- Affordable. Asphalt shingles are a great, middle-of-the-road product, lasting the optimal amount of time for the quality.
