Asphalt shingles are one of the most popular materials used in residential roofing. They are relatively inexpensive, come in a variety of colors and textures, and require minimal maintenance. 

How Asphalt Shingles Are Made

Asphalt shingles have been around for over 100 years, so it’s no surprise that many homeowners prefer them to other types of roofing materials, even though other materials, like cedar roofing, are also popular. But how exactly are asphalt shingles made? In this blog post, we’ll take a look at the process from start to finish.

Overview of the Process

Asphalt shingle production begins with the mixing of asphalt, granules, and fiberglass. This mixture is then heated to a high temperature and poured into molds that create the shape of each individual shingle. The molds are then pressed together tightly to ensure the materials bond properly. Once cooled, the shingles are cut into various shapes and sizes before being packaged for delivery or installation.

Materials Used in Asphalt Shingles

The three main materials used in asphalt shingles are asphalt, granules, and fiberglass. Each of these components plays an important role in the quality and longevity of the final product. Let’s take a closer look at each one:


Asphalt is the primary component of asphalt shingles and acts as an adhesive to hold everything together. It’s typically made from petroleum-based products, although recycled materials can also be used. Asphalt helps create a waterproof seal that will protect your roof from water damage and leaks.


Granules are made from crushed stone and provide an extra layer of protection from the elements. They also give asphalt shingles their unique color and texture. Granules reflect UV rays, which helps keep your home cooler in the summer months.


Fiberglass is a light material that helps asphalt shingles stay strong and last longer. It also helps keep them flexible, so they can withstand extreme temperatures without cracking or splitting.

Quality Control

The quality of the asphalt shingles is closely monitored throughout the production process. Samples are taken at various stages to ensure that the materials used meet industry standards for strength, flexibility, and waterproofing. Asphalt shingle manufacturers use strict quality control protocols to guarantee a high-quality product that will last for many years.
