Asphalt shingles are the most commonly used roofing material in the United States, and for good reason. They are affordable, durable, and come in a wide variety of colors and styles. In this article, we will take a closer look at asphalt shingles, including their composition, benefits, and drawbacks.
Composition of Asphalt Shingles
Asphalt shingles are made up of several layers of materials, each with its own specific purpose. The base layer is typically made of fiberglass or organic materials, such as paper or felt. This layer provides the shingle with strength and stability.
The next layer is the adhesive layer, which is made of asphalt and helps to hold the shingle together. The third layer is the asphalt layer, which gives the shingle its water-resistant properties. The final layer is the granule layer, which is made up of small particles of ceramic or rock that help to protect the shingle from the sun’s UV rays.
