What are asphalt shingle granules?

Asphalt shingles is one of the most popular roofing options in today’s market, but very little seems to be discussed about the granules found on asphalt shingles. Shingles are very easy to install and are arguably more cost-effective compared to other roofing materials, like slate, tile or stone. While they might not last as long as these materials, they still offer a considerable amount of service life, around 20 years or more, as long as they are taken care of properly. However, some homeowners might notice some asphalt shingle granules in their gutters and downspouts and are worried about what this means.

Why Are Asphalt Shingle Granules Important?

One of the most prominent aspects of asphalt roofing shingles are the stone granule surfaces. This surface is made from crushed hard rock which is made to exact granular size specifications. These granules help prevent discoloration caused by blue-green algae, and they also reflect most of the sun’s harmful heat, prolonging your roof’s lifespan. In fact, some regions require asphalt shingle roofs to have these granules for safety compliance. It also gives your shingles the ability to shed water and prevent moisture from infiltrating your home. 

What Happens When I Lose Granules?

If you notice that you’re losing granules at an alarming rate, it’s definitely time to have a roof repair or even a roof replacement project. This is especially true after severe weather events like storms or high winds. You can also experience granule loss if there is a lot of debris on your roof, such as fallen branches. Don’t hesitate to call your roofing contractor right away for assistance. You’ll have to cut your trees back to solve this issue. To avoid dealing with granule loss for the foreseeable future, make sure that you have your old asphalt roof replaced with a brand-new tile roof that is resistant against the elements.
