Common Questions

What causes those dark streaks on Pittsburgh roofs, and can you fix them?

Those dark streaks are typically algae growth, often called Gloeocapsa magma, which thrives in our humid climate. It's more than just a cosmetic issue—it can retain moisture and degrade shingles over time. We offer professional roof cleaning services that safely and effectively remove these stains without damaging your shingles, restoring your roof's appearance and health.

I'm finding granules in my gutters. Is this a serious problem for my Pittsburgh home?

Finding some granules is normal early in a roof's life, but excessive loss is a serious sign of aging or storm damage, common here. Those granules protect shingles from UV rays. We provide thorough roof inspections to assess granule loss, identify the cause, and recommend precise repairs or a replacement if needed to prevent leaks and extend your roof's lifespan.

As a Pittsburgh homeowner, how can I protect my roof from these common issues?

Proactive maintenance is key. We recommend annual visual inspections, especially after severe weather, and keeping gutters clear to prevent moisture buildup. For new roofs or replacements, we install algae-resistant shingles specifically designed for our climate. Our team can create a tailored maintenance plan to help your roof withstand Pittsburgh's conditions and avoid costly repairs down the line.
