5 Causes of Granule Loss on Asphalt Shingle Roofs

Asphalt shingles are the most popular roofing material in the U.S. by far. Their looks, reliability, versatility, and affordability make them a great option for homeowners. The granules on their surface add to their reliability by blocking UV rays that damage the shingles, and by adding stability to the shingle. Unfortunately, over time granules can wear down, affecting both the looks and structural integrity of the roof. If the damage is too extensive, you might have to call a roofing company in Jacksonville for repairs. Thankfully, this can usually be slowed down with a little bit of knowledge and routine maintenance. Understanding the causes of granule loss can help you slow down the aging process of your roof and help it last longer.

Excess Particles

Part of the problem could be excess particles that weren’t properly embedded when the shingles were manufactured. These excess granules come loose and fall off throughout the shingles’ lifetime. If there’s a lot of excess particles they can even shed during the initial installation process. Over time, as wear and tear sets in, the rate increases. This is a reason to make sure you are getting the highest quality shingles available!

Accumulated Wear and Tear

The rate of granule loss could increase as the shingles get more beaten up by the environment. Sun, wind and rain degrade even the best shingles over time. Even though there might not have been excess particles, they will start to wear off over time.

An inspection by a roofing company in Jacksonville can determine if the deterioration is expected based on the roof’s age, or if it’s worse than usual. Rapid granule loss could be due to extreme conditions such as hurricanes and other strong storms. It could also be due to inferior quality shingles.

Inconsistent Washing-Off Patterns

If the materials making up the shingles aren’t consistently spread out, some parts might wash off more than others. This means shingles can develop “bald spots.” Over time, these spots can worsen, leading to leaks or worse. This is where a professional inspection by a roofing company in Jacksonville can help. A pro can identify these bald spots and do something about them before they become a bigger problem.


The Jacksonville climate is quite harsh to shingles. The heat and sunlight can cause blistering, one of the more damaging ways the tiles are worn down. The blisters on the surface of the shingles form when moisture gets trapped inside the tiles. The moisture accumulates and the heat and sunlight cause it to expand. Blistering shingles are a sign that you need to repair your roof.

Physical Impact

Climb on the roof a lot? Have storms or hurricanes caused debris to fall on your roof? Physical impacts will affect the structural integrity of the shingles and can result in granule loss. Whether it’s from footsteps, accidents, work-related activities or the forces of nature, this damage accumulates and degrades the shingles over time.

Schedule an Inspection with a Licensed & Insured Roofing Company in Jacksonville

Those are the causes of granule loss on asphalt shingle roofs, which independently contribute to the damage and degrading of shingles and roofs. They can combine and speed up the process. This is why asphalt shingle roofs will need checking, sooner or later. A licensed and insured roofing company in Jacksonville can determine if repairs or replacement are necessary.
