You’ve probably seen them before, little sand-like particles in your gutters or at the base of your downspouts. These are asphalt shingle granules, and they play a vital role in protecting your roof and your home. While it’s normal for a roof to lose some granules over time, excessive granule loss can be a sign of a bigger problem. In this article, we’ll explore the causes of granule loss, how to identify it, and what you can do to protect your New Jersey or Pennsylvania home.
What Are Shingle Granules and Why Are They Important?
Asphalt shingles are made of a fiberglass or organic mat that’s coated with asphalt and then covered with a layer of mineral granules. These granules serve several important purposes:
- UV Protection: The granules act as a sunscreen for your roof, protecting the underlying asphalt from the sun’s harmful UV rays. Without this protection, the asphalt would dry out, crack, and deteriorate quickly.
- Fire Resistance: The granules are made of a fire-resistant material, which helps to protect your home from the spread of fire.
- Weather Protection: The granules provide an extra layer of protection against wind, rain, and hail. They also help to give the shingles their color and texture.
What Causes Granule Loss?
There are several reasons why your roof might be losing granules. Some are a normal part of the aging process, while others can indicate a more serious problem.
- Age: As your roof ages, the asphalt that holds the granules in place will start to dry out and become brittle. This can cause the granules to loosen and fall off. This is a normal part of the aging process, and it’s one of the reasons why you’ll eventually need to replace your roof.
- New Roof Installation: It’s normal to see some granule loss on a brand-new roof. During the manufacturing, packaging, and installation process, some granules will inevitably be loosened. These excess granules will typically wash off in the first few rainstorms.
- Weather: Severe weather, such as heavy rain, high winds, and hail, can all cause granule loss. Hail is particularly damaging, as it can knock the granules off the shingles and even puncture the underlying mat.
- Improper Installation: If your roof was not installed correctly, it can lead to premature granule loss. For example, if the shingles were not nailed down properly, they can be more susceptible to wind damage.
- Manufacturing Defects: In some cases, granule loss can be a sign of a manufacturing defect in the shingles. This is more common with lower-quality shingles.
- Foot Traffic: Walking on your roof can cause the granules to loosen and fall off. This is why it’s best to leave roof inspections and repairs to the professionals.
How to Identify Granule Loss
So, how can you tell if your roof is losing an excessive amount of granules? Here are a few things to look for:
- Granules in Your Gutters: The most obvious sign of granule loss is a large accumulation of granules in your gutters. When you clean your gutters, pay attention to how many granules you find. A few granules are normal, but if you’re scooping out handfuls, it could be a sign of a problem.
- Bald Spots on Your Shingles: Take a look at your roof from the ground. Do you see any areas where the shingles look bare or discolored? These “bald spots” are a clear sign of granule loss.
- Exposed Asphalt: If the granules have worn away, you may be able to see the underlying black asphalt. This is a serious problem, as the asphalt is now exposed to the elements.
- Cracked or Curling Shingles: Granule loss can cause the shingles to become brittle and start to crack or curl at the edges.
What to Do About Granule Loss
If you’ve noticed any of the signs of granule loss, it’s important to take action. The first step is to have your roof inspected by a professional roofing contractor. At Nailed It Roofing, we offer free roof inspections to homeowners in New Jersey and Pennsylvania. We’ll assess the extent of the granule loss and let you know if a repair or replacement is necessary.
In some cases, a simple repair may be all that’s needed. For example, if you have a few damaged shingles, we can replace them to prevent further granule loss. However, if the granule loss is widespread, or if your roof is nearing the end of its lifespan, a full roof replacement may be the best option.
