Those black streaks on your roof are living algae slowly eating your shingles. We kill and remove them with a safe, low-pressure soft wash that protects your roof and restores its original appearance.
The dark staining you see running down your shingles is a cyanobacteria called Gloeocapsa magma. It feeds on the limestone filler in asphalt shingles, breaking down the material that gives shingles their durability and UV protection over time.
Left alone, it retains moisture, accelerates shingle granule loss, and can void manufacturer warranties. It also makes your home look poorly maintained from the street, affecting curb appeal and resale value.
Pressure washing a roof forces water under shingles, strips granules, and can cause immediate damage. Soft washing uses low pressure and a professional-grade solution that kills the algae at the root and rinses it away cleanly, no shingle damage, no warranty issues.
We treat the entire roof surface and address every type of biological growth in a single visit.
The most common roof type in the area. Our soft wash solution fully kills Gloeocapsa magma algae and removes all streaking without lifting or damaging a single shingle.
Standing seam and corrugated metal roofs cleaned to remove algae, oxidation, and biological buildup using methods safe for painted and coated metal surfaces.
Moss and lichen hold moisture against the roof surface and physically lift shingles over time. We treat and remove active growth and apply a treatment to slow regrowth.
The ridge line and valley intersections are common spots for heavy buildup. We treat these areas with extra attention as part of every roof wash.
Algae and staining on the fascia and the top edge of gutters are addressed as part of the roof wash, so the whole roofline looks clean when we're done.
After the wash, we apply a residual treatment that continues killing algae spores and slows the return of black streaking, extending the time between cleanings.
Safe, thorough roof cleaning handled right from the first call.
We assess your roof's pitch, size, material, and level of algae or moss growth to give you an honest, upfront price with no surprises.
We wet and cover all surrounding landscaping, close gutters at the downspouts, and protect any sensitive plants or surfaces near the roofline before applying solution.
Our cleaning solution is applied at low pressure across the entire roof surface, dwells to fully kill algae, moss, and lichen, then is rinsed clean.
We do a full rinse of the surrounding landscaping and gutters, inspect the result from the ground, and confirm everything looks right before we leave.
