We never pressure wash shingles. A low-pressure soft wash treats the growth, and remaining stains usually fade over the following weeks of rain.
- Asphalt shingle and metal roofs
- Commercial flat roof membranes
- Black algae streaks
- Moss and lichen
We check the roof first. Damaged or failing roofs may not be good candidates.
