Have you ever cleaned your gutters and noticed tiny, black granules accumulated at the bottom? Did it cause you alarm? Fortunately for you, those tiny black granules are usually not cause for concern. In fact, they’re quite normal, and you should expect them if your roof is new. However, there are certain instances in which black granules may indicate the need for roof repair or replacement. At the Construction Group, our roofing contractors would like to keep you educated about the state of your roof. If you’ve noticed black granules in your gutter, read on to find out what they might mean.


Gutter Granules from Asphalt Shingles

If your roof has asphalt shingles, you may occasionally notice granules in your gutters. While it may be a bit alarming, it’s quite normal due to the asphalt shingle construction process. This type of shingle contains a core material coated with multiple layers of asphalt. The asphalt functions to protect the inner core of the shingle, provide water resistance, and to protect the core from the sun’s UV rays. For further protection, the top layer of the shingle contains finely crushed minerals. These minerals come in a variety of colors based on the homeowner’s preference.


Why Are the Granules Coming Off?

If you live in an area with frequent inclement weather, you’re bound to notice granules falling off your shingles. Asphalt shingles are durable and long-lasting, but they are still subject to severe weather. High winds and frequent, heavy rain can cause the minerals to loosen and tumble down your roof. When they do, they end up in your gutter, where they collect over time. When it’s time to clean your gutters, there may be an abundance of them at the bottom. You may be shocked upon observation, but this phenomenon doesn’t necessarily mean you need a new roof.


When Should You Call Professional Roofing Contractors?

A few granules in your gutters isn’t cause for concern; however, there are circumstances in which you should call the professionals. If you notice an excessive accumulation of material at the bottom of your gutters, it’s time to look for other roof warning signs. As your roof ages, you may notice the following signs:


●        Missing shingles

●        Partially detached and flapping shingles

●        Bald spots

●        Curled edges

●        Cracked shingles


If you observe any of these signs, it may be time to replace your roof. Once your shingles have reached the 20-year mark, it’s also time to consider contacting professional roofing contractors.
