Roof Granules
A shedding roof is normal. Comp roofs shed early on in their life, when they are damaged, and towards the end of its lifespan. The granules lost are almost like sand. Over time, and surprisingly quickly, this sand becomes too heavy for rain water to push. As the sand builds up, the natural flow of water near your home slows down.
In the video, you can notice the roof is still in good shape and that is enough “roof soot,” as I like to call it, to cause water to start building up. Allowing the weight in the gutter to build can be a dangerous and costly mistake.
