When I put my ladder on a roof and climb up to the gutter’s edge and look inside and see lots of granules, my mind starts to race with all of the reasons why it might be happening. What’s going on with this roof?

Granules in the Gutter

Granules in the Gutter

Granules are colored, ceramic pieces about the size of grains of sand, and are attached to the tar mat that makes up your shingles. They give them beautiful color and, most importantly, protect your shingles from the UV rays and storms that pelt down on them. Granules are one of the many ways we can tell how healthy your roof is with just a glance. When your shingles start to lose granules, we recommend calling for one of our free roof replacement estimates. You may have to replace your roof sooner than later once this starts.

Excessive granule loss can be the side effect of several issues. It could be poor ventilation or a manufacturer’s defect. Maybe the homeowner is over-cleaning their roof to try to keep the moss off, or they made the mistake of hiring a company that uses pressure washing to clean the roof. Whatever the case, we need to get to the bottom of it and figure out why it’s happening. It’s a lot like detective work, and your roof holds all the clues we need.

We want you to get the most life out of your roof that you possibly can. We care about the health of your roof, and if we can keep your roof from needing premature replacement, we will do everything we can to help it.

If you have questions, give us a call. We’ll come out, take a look at your shingles, and help you figure out how to address your concerns. Roof Life of Oregon can help.
