Shingles 101 - The Process of Making and Installing Asphalt Shingles
Introduction: Asphalt shingles are the most popular roofing material for residential buildings due to their affordability, durability, and ease of installation. This guide will provide an easy-to-understand explanation of how asphalt shingles are made and installed, offering insights into the manufacturing process and the steps involved in their installation.
Manufacturing Asphalt Shingles
Raw Material Preparation:
- Asphalt: The primary component of asphalt shingles is asphalt, a sticky, petroleum-based material. It is derived from crude oil and undergoes a refining processes to achieve the desired consistency.
- Fiberglass Mat: A strong, lightweight fiberglass mat is used as the base for asphalt shingles. It provides strength and stability to the shingles.
- Mineral Granules: Mineral granules are applied to the surface of asphalt shingles to protect against the sun’s UV rays and enhance their aesthetic appeal
- The fiberglass mat is coated with a layer of hot asphalt to provide waterproofing and strengthen the shingle.
- This asphalt-coated mat passes through a machine where fine mineral granules are embedded into the top surface, improving durability and providing color variation.
- In a shingle manufacturing machine, multiple layers of the coated mat are assembled together.
- The machine cuts the layers into individual shingles of desired size and shape.
- The shingles are then cooled and packaged for distribution.
