Looking for roof cleaning in Orange, CT? We look at the surface first, choose the right method and pressure for it, and give you a price before any work starts. You may also hear it called roof washing, roof soft washing or roof algae removal.
Method and pressure
No pressure on roofs: high pressure strips the protective granules from shingles and can crack tile. Roofs are cleaned with a soft wash solution and a gentle rinse.
Signs you need roof cleaning
- Black or dark streaks running down the roof
- Green moss or lichen spots, often on the north side
- Roof looks older than it is
- Moss lifting the edges of shingles
- A home inspector or insurer has noted roof growth
Why it gets dirty
- Roof algae (often Gloeocapsa magma) spread by wind
- Shade from trees and the north-facing side staying damp
- Debris piles in valleys that hold moisture
- Moss and lichen that root into the roof surface
What you can do yourself
- Keep valleys and gutters clear of leaves and pine needles
- Trim branches to let in sun and air
- Consider zinc or copper strips near the ridge to slow regrowth
- Look from the ground with binoculars instead of climbing on the roof

Serving Orange, CT and nearby towns
Black algae streaks are common on asphalt roofs in Connecticut, particularly on north-facing slopes and under trees. Soft washing removes them without stripping the granules that protect the shingles.
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.

Roof Cleaning: frequently asked questions
How much does roof cleaning cost in Orange, CT?
Roof Cleaning typically costs $400-$1,000 for a typical single-story or two-story home, and usually takes 2-4 hours. The exact price depends on the size and condition, and you get it before any work starts. Call (877) 658-5887 for a free quote.
Do you use high pressure for roof cleaning?
Roof Cleaning is done with soft wash (no pressure). Low pressure and the right solution remove growth and dirt without damaging the surface, and the growth takes longer to come back.
Is roof cleaning the same as roof washing?
Yes. Roof washing, roof soft washing or roof algae removal are other names for roof cleaning. Whatever it's called, we use soft wash (no pressure) and match the pressure and cleaning solution to the surface.
Is roof cleaning safe for my plants and pets?
We pre-wet plants and lawns, keep cleaning solutions diluted to what the surface needs, and rinse landscaping again when we finish. Keep pets and children inside until surfaces are rinsed and dry.
How often should I schedule roof cleaning?
Every 3-5 years, or when streaks return. Shade, nearby trees, humidity and heavy traffic mean more frequent cleaning; sunny, dry spots can go longer. Our free cleaning frequency tool gives a recommendation for your climate.
What if it rains on the day?
Light rain doesn't stop most washing, but heavy rain, high wind, lightning and freezing temperatures do. If the weather isn't right, we reschedule at no charge. Our work is backed by a satisfaction guarantee.
