The granules on the top layer of your asphalt shingles play an integral role in your roof’s overall health and performance. Local roofing contractor Precision Remodeling Solutions highlights some of the things you need to know about these important components.

About Asphalt Shingle Granules

Made of crushed rock and ceramic, the granules are the most visible parts of the asphalt shingles. During the manufacturing process, these are applied on the exposed side of the asphalt-soaked organic felt or fiberglass matting.

Made of ceramic and crushed rock, these are processed into a variety of colors to give them long-lasting colors. You can find asphalt shingles in the market that feature either a single base color or multiple blends of color tones and shades. Also, granules are often mixed with additional components, including copper granules that help fight algae discoloration and “reflective” bits to allow the roof to reflect significant amounts of heat.

The Importance of Asphalt Shingle Granules

One of the main functions of asphalt shingle granules is to protect the whole roof against the sun’s ultraviolet (UV) rays and extreme temperature changes. As long as the shingles are properly installed and maintained, your roof’s shingles are less likely to show signs of damage like warping, curling, or cupping.

Without granules embedded on the surface of each shingle, the roof can’t shed water effectively and efficiently whenever it rains or snows. The roof also becomes less appealing and attractive when seen with the rest of your home’s exterior, looking plain and flat. This usually happens when the roof is nearing the end of its life span. Apart from normal wear and tear, granule loss can also be caused by blisters, hail or impact damage, and loss of adhesion.

Granule loss must be given immediate attention as soon as possible. Contact our GAF-certified roofing pros at  Precision Remodeling Solutions today so we can evaluate your roofing system through a thorough inspection. Give us a call at (215) 360-5857 or fill out our contact form to get started.
