Granule loss on your asphalt shingles - everything you need to know

Asphalt shingles are a popular roofing material due to their durability and affordability. However, over time, asphalt shingles can develop issues such as granule loss. Granule loss can impact the shingles' ability to protect your home from the elements and can indicate the need for repairs or replacement. In this blog post, we'll cover everything you need to know about granule loss on your asphalt shingles, including the causes, how to identify it, and what to do about it.

What is Granule Loss on Asphalt Shingles?

Granule loss on asphalt shingles is the loss of the small, granular particles on the surface of the shingles. These granules serve several important functions, including protecting the shingles from UV rays and providing fire resistance. When granules are lost, the shingles become more vulnerable to damage from the sun, wind, and rain. Granule loss can occur due to a variety of factors and can lead to premature shingle failure.

What Causes Granule Loss on Asphalt Shingles?

There are several factors that can cause granule loss on asphalt shingles, including:

1. Age: As asphalt shingles age, they become more prone to granule loss. Over time, the granules can become loose or dislodge from the shingles.

2. Hail: Hailstorms can cause significant damage to asphalt shingles, including the loss of granules.

3. Foot traffic: If you have an asphalt shingle roof that is frequently walked on, such as for maintenance or to access a rooftop deck, the granules can become dislodged.

4. Poor quality shingles: Some manufacturers may produce low-quality shingles with less durable granules that can become dislodged easily.

5. Poor installation: Improper installation can lead to premature shingle failure, including the loss of granules.

How to Identify Granule Loss on Asphalt Shingles

Identifying granule loss on asphalt shingles is relatively easy. Here are a few things to look for:

1. Discolored or faded shingles: If your asphalt shingles appear discolored or faded, this could be a sign of granule loss.

2. Loose granules in gutters: If you notice small, granular particles in your gutters, this could be a sign of granule loss.

3. Bald spots on shingles: If you see areas on your roof where the shingles appear to be missing granules, this is a clear sign of granule loss.

4. Shingles that appear shiny: When the granules are lost, the asphalt surface underneath can become exposed, making the shingle appear shiny.

What to Do About Granule Loss on Asphalt Shingles

If you've identified granule loss on your asphalt shingles, there are a few steps you can take:

1. Repair or replace the affected shingles: If the damage is limited to a few shingles, you may be able to repair or replace them yourself. However, if the damage is extensive, it's best to hire a professional roofing contractor.

2. Improve attic ventilation: Poor attic ventilation can lead to heat buildup, which can accelerate the deterioration of your asphalt shingles. Improving attic ventilation can help to extend the life of your shingles and prevent granule loss.

3. Install a new roof: If your asphalt shingles are nearing the end of their lifespan or if they have significant damage, you may need to replace your entire roof.
