There Is A Multi-Step Process To Manufacture Shingles.
Roofing shingles are manufactured using a combination of asphalt, fiberglass or organic material, and various mineral fillers. The process of manufacturing roofing shingles involves the following steps:
- Mixing the asphalt: The first step in the manufacturing process is to mix the asphalt with other ingredients such as mineral fillers and stabilizers. This mixture is heated to a high temperature to make it fluid.
- Adding the fiberglass or organic material: Once the asphalt mixture has been heated, fiberglass or organic material is added to it to provide strength and stability to the shingle. The organic material used in shingle manufacturing is typically made from recycled paper, wood fiber, or other similar materials.
- Shaping the shingle: The mixture of asphalt and fiberglass or organic material is then pressed between two rollers to shape it into the desired size and shape of the shingle. This process is called mat formation.
- Adding granules: After the shingle has been formed, colored granules are added to the surface of the shingle. These granules serve several purposes, including providing UV protection, improving the shingle’s durability, and enhancing its appearance.
- Coating the back of the shingle: Once the granules have been applied to the front of the shingle, a coating of asphalt is applied to the back of the shingle to provide additional waterproofing and adhesion.
- Cutting the shingles: After the coating has been applied, the shingle is cut into individual pieces to create the final roofing shingle product.
The specific manufacturing process for roofing shingles may vary slightly depending on the manufacturer and the type of shingle being produced, but these steps generally describe the process used for most types of roofing shingles.
