Columbus roof cleaning
Roof cleaning in Columbus, OH
Black streaks on asphalt shingles are algae. We kill it with a low-pressure wash so the granules stay on the roof.
Gloeocapsa magma — the black streaks on Columbus roofs — is living in the limestone filler of the shingles. High pressure strips granules and can void a warranty. Soft washing is the method roofing manufacturers expect: a low-pressure application, dwell time, and a controlled rinse.
We clean asphalt, cedar, slate, tile, and metal. Metal roofs have their own page; most Columbus subdivisions are architectural shingles, and that is the work we do every week.
Why the streaks come back if you blast them
Pressure knocks the surface stain off and leaves the organism in the mat. The streaks return, and you have fewer granules. We treat the biology so the roof stays clean longer.
Same-day pairing with a house wash
We usually wash the roof first so rinse water can run the siding before we wash the walls. One mobilization, one quote, one finished elevation.
