Why Your Roof Needs Soft Washing

Asphalt shingles are manufactured with protective granules that reflect sunlight and regulate roof temperature. Biological growth — algae, moss, lichen — colonizes these granules, preventing them from functioning effectively and accelerating shingle degradation. Left untreated, this buildup can shorten the life of your roof by years and void some manufacturer warranties.

High-pressure washing is never appropriate for shingles. Excessive pressure dislodges the protective granules, which cannot be replaced and are critical to shingle performance. Soft washing is the ARMA (Asphalt Roofing Manufacturers Association) recommended method for cleaning asphalt roofs.

What We Treat

  • Gloeocapsa magma — the bacteria responsible for the black streaks and staining you see on shingles
  • Green and black algae colonies
  • Moss and lichen (a combined fungus/algae growth)
  • Mildew and organic debris buildup
  • General weathering discoloration

How Roof Soft Washing Works

1
Inspection & prep
We assess the roof condition, identify heavy growth areas, and protect any landscaping and surfaces below from solution runoff.
2
Solution application
A sodium hypochlorite and surfactant mix is applied at low pressure across the entire roof surface, working from ridge to eave.
3
Dwell & treatment
The solution dwells on the surface, penetrating and breaking down biological growth at the root. You'll often see the growth turn white as it's treated — that means it's working.
4
Rinse & natural wash-off
The roof is rinsed, and any remaining residue continues to wash away naturally with rain over the following weeks. Heavier buildup may require a second application.
What to Expect After Treatment

Results are often visible immediately, with the roof appearing noticeably cleaner within days. As rain washes residual growth away over the next few weeks, the roof continues to brighten. Some heavy lichen or moss infestations may require a follow-up treatment — we'll advise you honestly upfront rather than oversell a single visit.
