An Overview of Asphalt Shingle Construction from Your Ann Arbor Roofing Contractor

Asphalt shingles are the most popular residential roofing material – and for good reason. Shingles made from asphalt tend to be less expensive to manufacture and purchase than other shingle materials. The installation of these shingles is also systematic and straightforward, making the roofing process efficient. In this post, your Ann Arbor roofing contractor, Sherriff-Goslin will give an overview of the construction of the two main types of basic asphalt shingles.

Fiberglass Asphalt Shingles

These shingles are made using a glass fiber reinforcing mat which is manufactured in the same shape of the shingle. The fiberglass mat is then coated with asphalt. Since the mat serves as reinforcement, it isn’t necessary to use as much asphalt as is needed in organic shingles. However, asphalt won’t stick to the mat, so a mineral filler is used to allow adhesion. The mat is also not waterproof by itself, however, 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 Asphalt Shingles

These shingles are made of a felt material created by saturating paper with asphalt, making it waterproof. Next, a coating of asphalt adhesive is applied on top and ceramic roofing granules are embedded, giving the shingles added 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 fiberglass and organic shingle types are used in some of the most common product varieties by asphalt shingle manufacturers, including three-tab, dimensional, and interlocking shingles. Your Ann Arbor roofing contractor, Sherriff-Goslin, will discuss the available shingle types with you to determine which is right for your roofing project.
