Roof Cleaning & Moss
Moss on the roof spreads to your array. Clean both in one visit.

Seattle's pollen seasons, road dust, moss spores and bird droppings build a film across your array that rain never fully rinses off — it just dries into mineral spots. Studies consistently show soiled panels losing 15-25% of their output, which means your investment is underperforming every sunny day.
We clean panels the way manufacturers recommend: purified, deionized water and soft brushes on a water-fed pole. No detergents that leave residue, no pressure washing that risks micro-cracks, no scratched glass. Roof-mounted or ground arrays, residential or commercial — your panels get back to full production, safely.

In the Seattle area, once or twice a year keeps output high — after spring pollen season and again before the short winter days when every watt counts.
No. Rain rinses loose dust but leaves a mineral film, pollen residue and bird droppings baked onto the glass. That's why panels in rainy Seattle still lose output without cleaning.
No — the opposite. We use deionized water and soft brushes, the method panel manufacturers recommend. High pressure or harsh detergents are what void warranties; we never use either.
