Shingle Granules: What They Tell About Your Roof and Gutters

Granules are what give your asphalt shingles color and protection against the sun’s harmful UV rays. They are embedded during manufacturing and can improve your roof’s durability, fire resistance and longevity. As long as applied correctly during production, these sediments should stay intact and withstand years of exposure to the elements. 


A local home improvement expert explains what shingle granules can tell you about your roof and gutters.

Possible Reasons There Are Granules in Your Gutters

Depending on the condition or age of your roof, granules on your gutters can mean different things. It’s normal for new roofs to shed granules. During packing, shipping, and installation, granules can get dislodged. You don’t need to worry if you see some granules in your gutters and downspouts after getting a new roof as it will eventually stop. Granule loss can also occur after an extreme weather event, but it doesn’t always mean that you need to get a new roof. 

What Granule Loss Say About About Your Gutters

Like roofs and decks, gutters need regular maintenance to function efficiently. When clogged with debris, water will overflow to your siding and back up to the roof. Shingle granule buildup in your gutters could be a sign that the system is misaligned or not maintained properly. 

When to Call a Professional

Roofs deteriorate as they age just like any other home exterior component. Significant granule loss is a common sign that a roof is reaching the end of its life. Check if your roof has bald spots, missing or loose shingles and sagging areas. If the system is at least 20 years old, it’s a strong indication that it needs replacement.
