Real Results from Johnstown
Professional roof treatment for Johnstown homes. Slate and shingle specialists. No pressure washing.
Johnstown is a charming small town in Licking County where tree-lined streets, historic homes, and a strong sense of community define the character of the village. Many of Johnstown's older homes feature slate roofs — some original to the 19th century — alongside newer construction with asphalt shingles and mixed-material rooflines that combine metal sections with slate or shingle. Ohio's humid climate creates ideal conditions for Gloeocapsa Magma algae, lichen, and moss, which colonize all roof types and produce the dark stains and biological growth that spread across rooftops throughout Johnstown.
Forza Roof Cleaning serves Johnstown homeowners with a safe, no-pressure treatment system designed for every roof type — including the delicate slate and mixed-material roofs that require specialized expertise. Our drone assessment captures every angle before we start, and our low-pressure treatment eliminates biological growth without ever walking on your roof. With a 5.0-star rating across 256 Google reviews and a quality commitment, Johnstown homeowners trust Forza to protect their investment.

"Our old Johnstown home has a mixed roof — slate on the main house and metal on the addition. Forza treated both sections perfectly. The slate came back to its original warm color and the metal sections look great too. They really know their stuff with different roof materials."
"The lichen on our slate roof had been building up for years and we didn't know who to trust with it. Forza's drone showed us exactly what was going on and their treatment was gentle but effective. The transformation was amazing — we can see the individual slate colors again."
"Professional from start to finish. Dwayne explained everything clearly, the crew was respectful of our property, and the results exceeded our expectations. Our Johnstown neighbors keep asking who cleaned our roof. Five stars."
