Roof Cleaning
The dark streaks running down your roof are gloeocapsa magma, a hardy algae that feeds on the limestone filler in asphalt shingles. Left alone it holds moisture against the roof, shortens shingle life and drags your whole house down visually.
You cannot pressure wash a roof. Doing it strips the granules that protect the shingle from UV, and it voids most manufacturer warranties on the spot. The correct method, and the one the asphalt roofing industry recommends, is a low pressure soft wash that kills the organism and lets rain carry the residue off over the following weeks.
That is what we do. No walking your roof more than necessary, no pressure, no granule loss. Just a treated roof that goes back to looking like the shingle color you paid for.
Winchester’s mature shade trees and Shenandoah Valley humidity make north facing roofs an easy home for algae. We treat a lot of shingle roofs across Frederick County that looked ten years older than they were, and the streaks are usually lifting the same afternoon.

Assess the roof
We check pitch, shingle condition and how far the growth has gone before quoting anything.
Protect below
Plants, beds and hardscape underneath get soaked down and covered where needed.

The treatment is applied at low pressure across the full roof plane so nothing is left half done.
Rinse and clear
Everything below gets rinsed, and loosened debris is cleared from the gutters and downspouts.

Good to know
-
Will this void my shingle warranty?
No. Pressure washing a roof is what voids warranties. We use the low pressure soft wash method that shingle manufacturers and the asphalt roofing industry recommend for exactly this problem.
-
How fast will the streaks disappear?
Most of the darkening lifts within hours. Heavier growth and lichen keep fading over the following weeks as rain rinses the dead organism away, so the roof keeps improving after we leave.
-
Is it safe for my plants?
Yes, with the prep we do. Landscaping gets thoroughly pre soaked so it cannot absorb the solution, and everything gets rinsed again afterward. We plan the runoff path before we start.
-
How often does a roof need this?
Usually every three to five years in our climate, though shaded and north facing roofs come back faster. We will give you an honest read on your roof at the quote.
