Granular Loss and What it Means for Your Roof

Mineral granules may appear to be just a decorative accent to your roof, but they actually serve as an additional protective layer to your shingles and home, and significant granular loss can reveal a lot about the health of your roof system. It’s important for homeowners to understand the function of shingle granules and common causes for granular loss to help spot damage and know when to contact a roofing professional for an inspection.

Why Do Roof Shingles Have Granules?

Mineral granules were added to the design of shingles because they help protect your roof from excessive sun exposure, which can eventually lead to damage and hasten the need for a roof replacement. Granules also add increased fire resistance to your roof, offering another layer of protection to your home.

What Causes Granular Loss?

As your roof ages, it’s completely normal to lose some granular textures. Though age is the most common cause of granule loss, there are several other factors that can contribute to the premature loss of this protective coating. Severe weather such as heavy rain, hail or strong winds can also knock your granules loose. Following a storm, you may find an increased amount of shingle granules in your gutters or in your yard.

How Can I tell if My Shingles Are Losing Granules?

Granular loss is something homeowners can be made aware of without having to climb on top of their roofs. To identify granule loss, simply walk the perimeter of your home and examine the area around your downspouts. When granules come loose, they often run through your gutter system with water and pile up on the ground. You may also detect granular loss by simply looking up at your roof. If you notice spots that look bare or discolored, it’s time to call a roofer for an inspection.

Do I Need to Replace My Roof?

Granules help keep your roof weather proofed, so without them, it’s easier for the sun and water to cause roof leaks and deterioration. However, shingle granule loss does not always mean you need a full roof replacement. Depending on the level of granule loss and age of your roof, you may be able to replace the damaged shingles without having to get a new roof.
