Granule Loss and UV Protection Damage: When to Be Concerned

Asphalt shingles protect millions of homes in the U.S. This popular material is known for its cost-effectiveness, durability and versatility. It comes in various styles and hues to complement different architectural designs. With proper installation and maintenance, this roofing option can last at least two decades.

Moreover, asphalt shingles are embedded with protective granules during manufacturing. These sediments safeguard them from the sun’s harsh UV rays. It isn’t uncommon for homeowners to worry when they see these granules in their gutters or on the ground. Read on to find out when shingle granule loss should be a concern.

Why Does Granule Loss Occur?

Granule loss is a natural part of the aging process for asphalt shingles. However, various factors can accelerate it, including harsh weather conditions like hail or strong winds. Poor installation can also result in excessive granule loss. As granules wear away, your roof’s defense against UV rays diminishes.

If you have a newly installed roof and noticed some granules have fallen on the ground, there’s no need to worry. These sediments are only likely excess from manufacturing. They often get dislodged during shipping and installation.

When Should You Be Concerned?

Is there a large amount of shingle granules in your gutters? Significant granule loss has occurred if your roof has bare or discolored patches. This issue can affect your roof’s strength and aesthetic appeal, meaning you must call experts.

The granules on asphalt shingles serve a critical role in protecting the underlying bitumen coating from UV rays. Over time, UV exposure can cause shingles to become brittle and crack, significantly reducing their effectiveness in waterproofing your home.

What Can You Do About This Issue?

Regular inspections and maintenance go a long way in preventing costly issues and prolonging your roof’s life. You should get a professional assessment at least once a year and after weather extremes. Experts can determine whether repair or replacement is the best course of action. If they recommend getting a new roof, consider investing in materials with enhanced UV protection and durability.
