Granules on the ground are a sign you might need a new roof

There are many signs that your roof might need attention. Some signs are obvious, such as a leaking ceiling. Other signs of a potential roofing problem aren’t quite as obvious.

The rain.

A client of ours recently got some rain. A lot of rain. A lot of rain in a short period of time. 1.22″ of rain in about an hour, to be more precise.

Between all that rain in a relatively short period of time, and the fact that their gutters were clogged with debris, their gutters were overflowing with rain water.

Overflowing gutters is usually a bad thing. It means water isn’t being diverted away from the house. You want water diverted away from your house so it doesn’t affect your house’s foundation and cause problems, such as leak into your basement.

Granules on the ground.

One good thing about their overflowing gutters is that a clue was left on their porch that pointed to a problem with their roof; the homeowner found asphalt shingle granules on the ground. Granules on the ground means they’re not on the roof where they belong, which means they might need a new roof.

If the rain they just got had been a light drizzle, rain water, and the granules, would have ran down gutters, down the downspouts, and into the ground where nobody would have seen them. In this case, we’re glad they were left on the ground where someone could see them and start investigating.

Sure enough, the homeowner called us out for an inspection and we found exposed fibers all over their roof.

We also found granules in their gutters.

This roof was caught just in time. Had the homeowner waited much longer, the roof would have started to leak into their attic which can cause a series of problems, such as mold.


If you find granules on the ground, or in your gutters, you might need a new roof. You know you need a new roof if you look at the shingles and you see exposed fibers, such as in the photo above. Some granules in the gutters isn’t necessarily bad, but a lot means it’s time to replace your roof. Exposed fibers means your roof might be leaking rain water into your attic and it’s time for a new roof.
