  1. Durability: Asphalt shingles provide long-lasting protection against the elements, offering a lifespan of up to 30 years.
  2. Affordability: Compared to other roofing materials, asphalt shingles are more budget-friendly without compromising on quality.

Among the various roof maintenance issues you may encounter, granule loss on shingles is one that could slip under the radar but poses significant risks if left unattended. Understanding what granule loss means for your asphalt shingle roof can help you take timely action, safeguarding both your home and wallet.

What Are Shingle Granules?

Shingle granules are small, mineral-based particles embedded on the surface of asphalt shingles. These granules serve multiple purposes, including providing UV protection, enhancing fire resistance, and adding aesthetic appeal to your roof. In addition, they also act as a protective layer for the underlying asphalt and help to regulate temperatures on your roof.

Components of a Roofing Shingle

  1. Base Mat: The foundation of the shingle, made from fiberglass or organic materials, provides strength and flexibility.
  2. Asphalt Coating: Ensures waterproofing and helps the shingle adhere to the base mat.
  3. Mineral Granules: These are added to the asphalt coating, offering protection against UV rays and physical damage.

Differences in Shingle Types

Understanding these components helps explain why granule loss can be detrimental to your roofing system.

Shingle Granule Loss: How It Happens

Several factors can contribute to granule loss on asphalt shingles. Understanding these causes can help you take preventative measures.
