Roof Cleaning in the Flathead Valley
Moss holds moisture against your shingles, lifts their edges, and lets snowmelt work its way underneath. Our low-pressure roof soft wash kills moss and algae without blasting away granules — the safe method recommended by shingle manufacturers.

Why it matters
- Removes moss, lichen, and black algae streaks
- Helps extend the life of your roof
- No high pressure, so shingles and granules stay intact

- 04Rinse gutters and downspouts; remaining growth washes away with weather
Common questions
Do you walk on my roof?
Only when it's safe and necessary. Most treatment is applied from ladders or the ground with low-pressure equipment.
When will the moss disappear?
Algae streaks usually lift right away. Treated moss dies and loosens over the following weeks as rain and snow rinse it off.
