Roof Washing & Soft Wash Roof Cleaning in Indianapolis
Those black streaks running down your shingles are gloeocapsa magma, a roof-eating algae that feeds on the limestone filler in asphalt shingles. Left alone it holds moisture, shortens shingle life and drives up cooling costs.
ICV Exterior Services uses the no-pressure soft wash method recommended by shingle manufacturers and the ARMA. We apply a cleaning solution that kills algae, moss and lichen, then let the rain rinse it away — no walking a wet roof, no blasted granules.
What's included
- No-pressure soft wash of the full roof plane
- Black streak, moss and lichen treatment
- Gutters and downspouts flushed after treatment
- Landscaping saturated and protected throughout
- Siding and windows rinsed on completion
Roof Washing questions
Does roof washing void my shingle warranty?
No. Soft washing is the cleaning method asphalt shingle manufacturers recommend. High-pressure roof cleaning is what voids warranties.
How long do the results last?
A properly soft washed roof usually stays clean for 3 to 5 years in central Indiana, depending on tree cover and shade.
