From the free quote to the final rinse, roof cleaning in Kettering, OH follows a simple process: inspect, protect, clean, rinse and check.
The right method for the job
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.
Is it time for 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
Where the grime comes from
- 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
Easy upkeep between cleanings
- 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

- Water forced under shingles and flashing
What happens on the day

- Pre-wet and protect plants and cover sensitive areas
- Apply a soft wash solution suited to the roofing material
- Let it work, then rinse gently or let rain finish the job as recommended
- Rinse gutters, downspouts and plants and check the results

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 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.
