Understanding Basic Asphalt Shingle Construction from Your Battle Creek Roofing Company
There are good reasons that asphalt shingles have become the most popular residential roofing material on the market. Asphalt shingles are relatively inexpensive to manufacture and purchase, and the installation is systematic and straightforward. In this post, your Battle Creek roofing company will look at two types of basic asphalt shingle construction.
Asphalt roofing shingles come in two main types – fiberglass and organic. Fiberglass shingles are made using a glass fiber reinforcing mat which is manufactured in the same shape of the shingle, such as the traditional tabbed shingle. It’s then coated with asphalt. Since the glass mat serves as reinforcement it’s not necessary to use as much asphalt as in organic shingles. However, asphalt won’t stick to the glass fiber mat, so a mineral filler is used to enable adhesion. The glass mat is also not waterproof by itself but when the mineral filler combines with the asphalt, it fills the holes in the glass fiber mat; rendering it waterproof. Ceramic granules are added to the asphalt in glass shingles to provide additional durability and protect the asphalt from the sun.
Organic shingles are made of a felt material created by saturating paper with asphalt, so it becomes waterproof. Then a coating of asphalt adhesive is applied on top and ceramic roofing granules are embedded, giving the shingles durability. Organic shingles contain 1/3 to 2 times as much asphalt as fiber glass shingles, which gives them more weight and stability. Many of the newer shingle designs utilizing this process, add a longer warranty against storm damage from high winds and driving rains. Their thick layered construction also makes them generally last longer, enabling more years to be added to the warranty.
Both of these shingle types are incorporated in some of the most common product varieties by asphalt shingle manufacturers, including three-tab, dimensional and interlocking shingles.
