Low-Pressure Treatment
We treat the roof with a cleaning solution rather than blasting it, because pressure washing shingles strips the granules that protect them.

Those dark streaks on a roof are algae, and moss holds moisture against the shingles. A low-pressure soft wash treats both without the shingle damage that pressure washing a roof causes.

We treat the roof with a cleaning solution rather than blasting it, because pressure washing shingles strips the granules that protect them.
We clear the black streaks from algae and treat moss that traps moisture against the roof surface.
We protect and rinse gutters, downspouts, and plantings so the runoff does not cause a second problem.
We work the roof safely and avoid unnecessary foot traffic on the shingles.

We look at the actual project and give you a clear price before any work starts.
Talk to usHigh pressure strips the protective granules off asphalt shingles and shortens the life of the roof, so we never use it up there.
Algae and moss come back if you only knock them loose, so we treat them for a result that lasts.
Moss holds water against the roof and speeds its wear, so clearing it protects the roof, not just its looks.
They are almost always algae. A soft-wash treatment clears the streaks and helps keep them from coming back quickly, without the damage that pressure washing would cause.
Not the way we do it. We use low pressure and a cleaning solution, never high pressure, because blasting a roof strips the granules that protect the shingles.
Clearing moss matters, because moss holds moisture against the shingles and speeds their wear. Treating it protects the roof, not just its appearance.
We protect and rinse gutters, downspouts, and landscaping so the runoff from the cleaning does not create a new problem.
It depends on shade and tree cover. A north-facing or heavily shaded roof grows algae and moss faster, so it may need more frequent attention.
