Roof Cleaning in Columbus, Ohio

Those dark streaks are caused by Gloeocapsa Magma — a cyanobacteria that feeds on the crushed limestone filler in asphalt shingles. It's extremely common in Ohio's humid climate and spreads from roof to roof via wind and birds. It's not just cosmetic — left untreated, it accelerates granule loss and can significantly shorten your roof's lifespan.

Most residential roof cleanings in Columbus range from $300 to $900 depending on roof size, pitch, and the severity of bio-growth. Cedar, slate, and tile roofs typically cost more due to the specialized care required. We provide free estimates with no obligation — call (888) 516-0008 or fill out our quote form.

Yes — treatmenting is the recommended cleaning method for every residential roof type. We adjust the chemical formulation and application method based on your specific roofing material. We never use high-pressure equipment that could damage shingles, crack tiles, or split cedar shakes.

Our treatment typically keeps roofs clean for 3–5 years because it kills bio-growth at the cellular level rather than just rinsing the surface. We back this up with a quality commitment — if anything comes back within 3 years, we return and re-treat at no charge.

No. We pre-wet all plant beds and landscaping before applying any solution, and we thoroughly rinse everything down after we're done. Our biodegradable solution is formulated to be safe for plants, pets, and people once it dries — typically within 30–60 minutes.

No — you don't need to be home. We just ask that all windows are closed and pets are kept indoors during the treatment. We'll send you before-and-after drone photos by email when the job is complete.
