Roof + Moss Treatment
Kill the moss, save the shingles. Soft-wash only.
Moss lifts shingles and can shorten roof life by 5–10 years. Replacing a 2,400 sq ft roof costs $18k+. A wash is a fraction of that.
We never pressure-wash a roof. We apply a soft-wash moss treatment that kills moss and gloeocapsa magma where they grow, brush out heavy buildup by hand, and finish with a clear rinse. Optional zinc strip install on request.

Will the moss come back?
Slowly. Zinc or copper strips installed at the ridge prevent regrowth for years. We can add that on if you'd like.
Can you do this in the rain?
Light rain is fine. Heavy rain dilutes the treatment, so we'll reschedule for free if the forecast turns.
