Real Results from Granville
Expert roof treatment for Granville's historic homes. Slate specialists. No pressure washing. No roof damage.
Granville is one of Ohio's most charming communities — a historic college town built around Denison University with tree-lined streets, beautifully preserved 19th-century architecture, and a village center that feels like stepping back in time. Many of Granville's finest homes feature original slate roofs that have endured for over a century, along with cedar shake and premium shingle roofs on newer construction. But Ohio's humid climate doesn't discriminate by architectural pedigree: Gloeocapsa Magma algae, lichen, and moss colonize slate tiles just as aggressively as asphalt shingles, producing dark stains and biological growth that obscure the natural beauty of these irreplaceable roofing materials.
Forza Roof Cleaning specializes in the kind of careful, no-pressure treatment that Granville's historic homes demand. Slate roofs require expertise — high pressure or aggressive chemicals can crack tiles, damage flashing, and destroy a roof that has protected a home for generations. Our drone-based assessment and low-pressure treatment system safely eliminates algae, lichen, and moss without ever walking on your slate. The transformation is dramatic: decades of biological buildup dissolve to reveal the original pink, terracotta, and gray tones of the slate beneath. With a 5.0-star rating across 256 Google reviews, Granville homeowners trust Forza to preserve their investment.

"Our 1890s home on Broadway has the original slate roof and it was covered in decades of lichen. We were terrified of hiring someone who might damage it. Forza's drone assessment showed us exactly what they'd be treating, and the results were breathtaking — the natural slate color came back beautifully. They clearly know what they're doing with historic roofs."
"We're near Denison and our slate roof had turned almost completely black with algae. Forza's treatment brought back colors we didn't even know were there — pinks, grays, terracotta. The neighbors can't believe it's the same roof. Worth every penny for a historic home like ours."
"Dwayne was incredibly knowledgeable about different roof types and took the time to explain exactly what was growing on our cedar shake roof and how they'd treat it. The results speak for themselves — our roof looks brand new. Highly recommend for anyone in Granville."
