When we handle soft washing for asphalt shingle roofs in Orange, CT, it comes down to three things: protecting your plants and property, cleaning with the right method, and walking the job with you at the end. With asphalt shingle roofs, the right approach is soft wash (no pressure).
How we clean it
Cleaning solution: A diluted sodium hypochlorite solution with surfactant; plants below are pre-wet and rinsed.
Caring for asphalt shingle roofs
The black streaks on many asphalt roofs are a type of algae, often Gloeocapsa magma, that feeds on the limestone filler in shingles. It is killed with a soft wash solution, not blasted off. The Asphalt Roofing Manufacturers Association advises against pressure washing shingles because it strips the granules that protect them.
Avoid: Pressure washing, which strips granules and shortens the roof's life, and walking on wet, slick shingles.
How often: Every 3-5 years, or when streaks return.

Humid summers in Connecticut grow green algae and black mildew on the shaded sides of homes, especially on vinyl and painted wood. A soft wash kills the growth rather than just knocking it off, so the siding stays clean longer.
Near the coast, salt air leaves a film on siding, windows, screens and railings that dulls finishes and speeds up corrosion on metal. Regular rinsing and washing help protect them.
