Roof Cleaning in Geauga County & Northeast Ohio
Low-pressure soft washing that removes algae, black streaks, and moss from your roof without damaging shingles or voiding your warranty.
What Is Professional Roof Cleaning?
Roof cleaning is the removal of algae, moss, lichen, and the dark streaking they cause from roofing surfaces. In Northeast Ohio, the combination of moisture and shade creates ideal conditions for Gloeocapsa magma — the algae responsible for the black streaks commonly seen on asphalt shingles.
Professional roof cleaning uses a soft wash method: low water pressure paired with professional cleaning agents that eliminate organic growth at the root. This approach is endorsed by the Asphalt Roofing Manufacturers Association (ARMA) as the appropriate method for cleaning asphalt shingles because it removes contaminants without displacing granules or stressing the shingle surface.
A clean roof looks better, lasts longer, and does not absorb and retain moisture the way an algae-covered roof does.

- Stop organic growth from deteriorating shingle granules over time

Roof Cleaning — Frequently Asked Questions
Why do black streaks appear on roofs?
Black streaks on roofs are typically caused by Gloeocapsa magma, a type of algae that feeds on the limestone filler in asphalt shingles. Once established, it spreads across the roof surface and retains moisture, which can accelerate shingle deterioration over time. Northeast Ohio's humidity and shade create favorable conditions for its growth.
Will roof cleaning damage my shingles?
When performed correctly using low-pressure soft washing with appropriate cleaning solutions, roof cleaning does not damage shingles. High-pressure washing can displace granules and shorten shingle life — which is why we use the soft wash method for all roof work. The ARMA specifically recommends this approach for asphalt shingles.
How long do roof cleaning results last?
Results typically last two to five years depending on the amount of shade, moisture, and tree coverage around your home. Properties surrounded by trees in shaded areas may see regrowth sooner. We can discuss what a realistic maintenance interval looks like for your specific property and conditions.
Will cleaning my roof affect my warranty?
The Asphalt Roofing Manufacturers Association recommends low-pressure soft washing as the appropriate cleaning method for asphalt shingles. Using this approach protects your shingles while cleaning them. We advise reviewing the specific terms of your shingle warranty if you have questions about coverage.
How do I know if my roof needs cleaning?
Visible dark streaks, green moss patches, or an overall discolored appearance are clear indicators of organic growth. Beyond appearance, leaving algae and moss untreated allows moisture to accumulate on the surface, which can accelerate granule loss and shorten the lifespan of the roof. If you are uncertain, we can assess during a quote visit.
