You Can See The Need For A Roof Repair
There are so many things to inspect to see how your roof is holding up and most require our expert technicians to evaluate. But there is one way to inspect for roof repair that is visible to you the homeowner. Often, you will be able to see signs of granular deterioration yourself.
So let’s talk about shingles and possible shingle damage to the roof on your home.
What is “Granular Deterioration”?
Granular deterioration is the loss of the little mineral particles that help protect roof shingles from weather’s harmful elements. There are many reasons that the loss of granules happens. Mostly, the reason is normal weathering over time.
About 80-percent of homes in Fort Bend County and Harris County are covered by asphalt roof shingles. Asphalt, sometimes called “composite shingles,” are designed to soften under heat to seal and be the proper coating material for the roof protecting your home. These shingles have a mineral stabilizer that make them more durable and more resistant to normal wear and tear. These are the “granules” added to shingles. They are very, very small pebbles of limestone or other stone. Shingles made with color have granules that are coated with a ceramic layer that gives them color.
The Causes of Granular Deterioration
The granules added to shingles during the manufacturing process are pressed onto the asphalt. Most granules become embedded in the thick, sticky, petroleum-based material. Some granules don’t make contact with the asphalt and are lodged among other granules. Pick up a shingle with your bare hands and you’ll notice the shingle dust from each tile. Don’t complain; the more granules, the more protection for your roof.
Then the rains come. Heavy water droplets will pound these little granules loose. The granules will be swept off your shingles and into your gutter system. (Whaaaat!?!? No gutters on your home? That’s bad for your foundation. Let’s talk gutters, too!)
Back to granules. Time and weather are the most common causes of granular deterioration, a common reason for a roof repair. There are others:
- Blistering – Exposed asphalt gets so hot under the sun that it bubbles and knocks more granules loose.
- Foot traffic – You’ve seen the movies where someone climbs out an upstairs window to sit on the roof and look up at the stars. If that happens a lot, guess what happens to the granules.
- South and West – In this part of Texas the heat from midday to sundown beats mercilessly down on your roof. The sides of the roof facing south and west take the brunt of the sun damage.
- Flaking – If there is an impurity in the asphalt the base of the shingle will break down and not hold the granules in place.
- Faulty manufacturing – If parts of your roof seem discolored from the rest of the roof, the problem is likely a subtle change in the manufacturing process. A different batch of shingles may wind up looking different because they’re not holding the granules as well as the rest of the roof.
Is Your Roof Missing a Lot of Granules?

You’ll just need professional help to make sure there is no underlying damage that needs to be addressed. So, call us.
