Cave pressure washing
Moss and algae love Astoria roofs. The long wet winters, coastal moisture and shade from nearby trees create the perfect conditions for black streaks and green clumps. A dirty roof holds water and can age faster than it should.
Cave pressure washing cleans roofs with a soft wash only. We never hit shingles with high pressure. Our treatment breaks down moss and algae, then we let the rain rinse it away over the following weeks. It is the safest way to restore a roof in this climate.

Removing moss and algae stops premature shingle wear.
A clean roof makes the whole property look newer.
Moss traps moisture against the roof surface.
We look at shingle type, pitch, moss coverage and any loose flashing.
Apply a low-pressure solution that kills moss, algae and mildew at the root.
The treatment continues working after we leave, rinsing clean with rain over time.
No. Soft wash is the recommended method for asphalt shingles and most roofing materials. We do not use high pressure.
Most improvement shows within days, with full results after several rains over a few weeks.
We use ground-level spraying when possible. Steep or fragile roofs may get a gentler approach from ladders or extensions.
