What Shingle Granules Tell You About Your Gutters

Asphalt shingles are the most widely-used roofing material in North America, thanks to their affordable price and ease of installation. However, when shingle granules land in your gutters, this can signal trouble for your roofing system, according to certified roofers.

The Composition of Asphalt Shingles

Asphalt shingles consist of either an organic or fiberglass base mat and layers of asphalt. The top layer is covered with ceramic-coated minerals. Once these granules are embedded in the surface, they act as a protective coating against the elements, specifically ultraviolet rays. This addition further improves the stability and weather protection of the roof.

It’s important to note that a newly-installed asphalt shingle roof will shed a few granules after a heavy downpour or high winds, but this doesn’t usually warrant an emergency roof repair. As the roof ages, more and more granules will collect in the gutters through normal wear and tear.

When You Should Worry About Granule Buildup

While you don’t need to be concerned if you find shingle granules in your gutters after a stormy day, it becomes a big problem once the shingle buildup reaches a thickness of 0.5 to 2 inches. These granules, in addition to leaves, twigs and bird droppings, can clog your gutters and cause them to overflow. When left unchecked for extended periods, clogged gutters can even lead to basement flooding and soil erosion. 

Poor gutter maintenance contributes to the accumulation of shingle granules in your gutters. Gutter professionals recommend cleaning out your gutters and downspouts at least twice a year, once in the spring and again in the fall. You might also consider installing gutter guards to minimize the time and effort required to keep your gutters in tip-top condition.
