Are Roof Granules a Sign I Need a New Roof?

Roof Granules

You might find them at the end of your downspout after a heavy rainstorm, or in your gutters when you are cleaning out leaves. The concern we often hear when homeowners find roof granules goes something like this:

“Is it normal to see so many granules?”


“At some point, will my roof be unprotected because all of the granules have worn off?” 

As a locally-owned and operated roofing specialist, we’ve been helping homeowners answer questions like these for years. We know how important it is to have peace of mind and confidence in a good roof over your head. In this blog, we’ll look at what’s normal and help you know when it’s time for you to have an expert assess your roof.

Why does my roof have granules?

Roof shingles have tiny granules that are made from crushed stone and minerals. They’re meant to provide a layer of protection from the elements. Particularly from sun exposure, which can create extensive wear in hot Mid-Missouri summers. Together, millions of granules on your roof shingles are an army of protection from the elements.

What causes roof shingles to lose granules?

In the manufacturing process, there is always an excess of granules that are added to roof shingles. Roofing manufacturers even allow for a loss of granules as part of a roof’s everyday wear and tear. So, when you get a new roof, you should expect to see excess granules, and it’s natural for the loose granules to come off when roofing installers walk on your newly installed roof. You’ll also see excess granules in your downspouts in the following few weeks. After a few rainstorms, you will gradually see less, but it’s completely normal to see them periodically.

How can I know if I need to replace my roof?

While it’s normal to lose granules, every roof has a lifespan. Of course, choosing a company that uses superior products can provide a longer-lasting roof. Still, in our experience, most people have inherited a roof from a previous homeowner or have lost track of how old the roof is.

There are some things you can spot as you look up at your roof, but ultimately only a skilled roofing contractor can tell you from a close-up inspection. In the meantime, here are some quick things to consider:

    • Do your roof shingles look old and have bald spots in places?
    • Do you see cracks in your shingles?
    • Do your roof shingles look curled or cupped?
    • Do you see any daylight in your attic?
    • Are other people in your neighborhood getting a new roof?

Now you can gain peace of mind for free.
