Hooper Roofing - Pittsburgh's Trusted Roof Repair

That 'black sand' is actually shingle granules, and in Pittsburgh, it's a common early warning sign. Our intense sun, heavy rains, and winter freeze-thaw cycles can cause premature granule loss, exposing the asphalt layer to faster deterioration. If you're seeing a significant amount in your gutters, it's time for a professional inspection. We can assess the extent of the wear and recommend targeted repairs or a replacement to prevent leaks and water damage to your home's structure.

Pittsburgh's humid climate and shaded neighborhoods create the perfect environment for moss, which holds moisture against your shingles and causes them to decay. Simply power washing it off can damage the shingles and it will grow right back. Our approach is more comprehensive. We safely remove the existing moss, then apply a specialized treatment to inhibit regrowth. More importantly, we can install zinc or copper strips along your roof ridge—a long-term, low-maintenance solution that uses rainwater to create a moss-resistant barrier.

As your local roofing experts, our goal is always to recommend the most cost-effective, long-lasting solution for your Pittsburgh home. For isolated issues like a small area of moss damage or granule loss from a single storm, a precise repair is often sufficient. However, if an inspection reveals widespread wear, aging, or underlying decking issues—common with our local weather patterns—a full replacement is the smarter investment to avoid recurring problems. We provide a clear, honest assessment so you can make the best decision for your home and budget.
