Granule Loss on Shingles: Spotting It, Understanding It, and Fixing It

One common issue your roof might face is granule loss on shingles. As a leading roofing company in the Boston area, D&G Exteriors specializes in new roofs, siding, window replacement, and decks. In this blog post, we'll help you understand granule loss, why it matters, and why you should trust a professional roofing contractor like D&G Exteriors to fix it.

What is Granule Loss on Shingles?

Granule loss occurs when the small, protective granules on your asphalt shingles begin to wear away, exposing the underlying asphalt layer. These granules are vital for protecting your shingles from harmful UV rays, weather elements, and improving their overall durability. Over time, granule loss can lead to a weakened roof, making it essential to address the issue promptly.

How to Spot Granule Loss

Spotting granule loss on shingles is relatively simple. When inspecting your roof, look for the following signs:

  1. Bald spots or uneven color on your shingles, indicating areas where granules have worn away.

  2. Granules collecting in your gutters or at the base of your downspouts.

  3. Shingles that feel smooth to the touch, rather than rough and textured.

If you notice any of these signs, it's time to consult a trusted roofing contractor like D&G Exteriors to assess your roof and recommend the best course of action.

Why Does Granule Loss Happen?

Granule loss on shingles can occur for several reasons:

  1. Natural wear and tear: Over time, shingles can lose granules due to aging and exposure to the elements.

  2. Improper installation: If shingles are not installed correctly, they may be more susceptible to granule loss.

  3. Severe weather: Heavy rain, hail, or wind can cause granules to loosen and fall off the shingles.

  4. Manufacturing defects: In some cases, granule loss can result from a defect in the shingles themselves.

Why Does Granule Loss Matter?

Granule loss matters because it can compromise the integrity of your roof. When shingles lose their protective granules, they become more vulnerable to UV rays, which can cause the asphalt to deteriorate and become brittle. This deterioration can lead to leaks, water damage, and even structural issues in your home. Additionally, granule loss can negatively impact your home's curb appeal and resale value.

Why Should You Fix Granule Loss?

It's essential to fix granule loss to protect your home from potential damage and maintain its overall value. A professional roofing company like D&G Exteriors can help you determine whether you need simple repairs or a full roof replacement, depending on the extent of the granule loss and the age of your roof. By addressing granule loss promptly, you'll ensure your roof remains in optimal condition, safeguarding your most significant investment—your home.
