How to Repair Granular Loss on a Roof (The Right Way)
If you've noticed bare patches or bald spots on your shingles, you might be looking at granular loss—a common roofing issue that often gets overlooked until it's too late. At Manny Roofing, we believe in educating homeowners so they can make confident, informed decisions. But here’s one thing we’ll be clear about up front: Repairing granular loss is not a DIY job. Here’s why.
What Is Granular Loss?
Asphalt shingles are covered with tiny, sand-like granules that serve an important purpose: they protect your roof from harmful UV rays, add weight to keep shingles in place, and provide fire resistance. Over time, weather, age, and improper installation can cause these granules to shed. While some shedding is normal—especially after a new roof installation—excessive or uneven loss is a red flag that something's wrong.
Signs You’re Dealing With Granular Loss
If you’re unsure whether granular loss is affecting your roof, here are a few indicators:
- Bare spots or exposed black patches on shingles
- Granules accumulating in gutters or downspouts
- Discolored shingles or uneven texture
- Leaking or moisture stains in your attic or ceiling
If you notice these symptoms, it’s time to call in the pros.
Why You Shouldn’t Attempt This Repair Yourself
We get it—YouTube makes everything look doable. But roof repair, especially when it involves granular loss, is more complex (and risky) than you think. Here’s why DIY isn’t the answer:
1. It’s Not Just Cosmetic
Granular loss often points to underlying issues like shingle deterioration or ventilation problems. A quick patch job won’t address what’s really going on beneath the surface.
2. Walking on a Compromised Roof Is Dangerous
Loose granules make surfaces slippery. One misstep can result in serious injury—not to mention further damage to your roof.
3. DIY Repairs Can Void Warranties
Attempting a repair without proper certification or technique can void manufacturer warranties. At Manny Roofing, we're GAF Master Elite® certified, which means our work meets the highest standards and keeps your warranty intact.
4. You Might Miss Bigger Issues
What looks like minor granule loss could be a sign of widespread shingle failure, storm damage, or aging materials. A professional roof inspection ensures nothing gets missed.
