Roof Soft WashingBlack Streaks Gone — Without Ever Pressuring Your Shingles
A zero-pressure treatment that kills streaks, moss, and lichen at the root and keeps your roof warranty intact.
What roof soft washing includes
Those black streaks on Charlotte roofs are gloeocapsa magma — an algae that eats the limestone filler in asphalt shingles. A pressure washer blasts off protective granules along with the stain, shortening roof life and voiding most manufacturer warranties. Our soft-wash treatment does the opposite: we apply an algae-killing solution at garden-hose pressure, let it dwell into every shingle course, and gently rinse. The stains die, detach, and wash away — granules stay put.
Every roof wash includes moss and lichen treatment on ridges and shaded slopes, a gutter-line rinse so dead growth doesn’t clog your downspouts, and a full ground-level cleanup of landscaping afterward.
- Zero-pressure algae treatment
Kills black streaks, moss, and lichen without touching granules.
- Safe for asphalt, tile & metal
Warranty-friendly method recommended by shingle makers.
- Ridge, valley & shaded-slope focus
Extra dwell time where growth is heaviest — usually the north face.
- Gutter-line rinse & ground cleanup
Downspouts flushed, beds rinsed, walkways left spotless.
How the visit goes
Roof treatments take two to five hours depending on size and pitch. Our technicians work from ladders and ridge anchors — we never need to walk fragile areas. You’ll see stains fade over the following days as the treatment finishes working; heavy moss may take a couple of rains to fully release.
Roof washing questions
No — soft washing is the method shingle manufacturers recommend. High-pressure washing is what voids warranties, because it strips the UV-protective granules. Our treatment never exceeds garden-hose pressure on the roof surface.
Most streaks rinse away the same day. Deep, years-old staining lightens immediately and continues fading over 2–4 weeks as the dead algae releases with rain. If any area needs a second pass, it’s free under our guarantee.
Only where it’s safe and necessary. We apply most treatments from ladders and ridges with extended wands, and we use proper anchors on steep pitches. Tile and older roofs get an entirely no-foot-traffic approach.
Your shingles are stained, not worn out.
