Restore Your Roof. Protect Your Home. Improve Curb Appeal.
Over time, Ohio roofs collect moss, algae, lichen, dirt, and debris that eat away at shingles, trap moisture, and shorten the lifespan of your roof. At Sentry Roofing, we provide safe, professional roof cleaning and moss removal services that restore your roof’s appearance and protect its long-term performance—without causing damage.
Our soft-wash, non-destructive cleaning methods eliminate growth at the root and help your roof last years longer.
Why Roof Cleaning Matters
Ohio’s climate—humidity, rain, shade, and seasonal temperature swings—creates the perfect environment for moss and algae to thrive. Left untreated, these growths can cause:
- Premature shingle deterioration
- Moisture absorption and rot
- Granule loss
- Lifted shingles
- Roof leaks
- Lower energy efficiency
- Reduced property value
Cleaning your roof isn’t just cosmetic—it’s an essential part of roof maintenance.

Can Moss Damage a Roof in Ohio? Yes—Here’s How
Moss acts like a sponge. It traps water, lifts shingles, and accelerates rot. In Ohio’s wet seasons, this moisture can:
- Soak into underlayment
- Freeze and expand (winter damage)
- Cause deck rot
- Lead to interior leaks
- Create mold in the attic
Cleaning and treating moss early prevents thousands in repairs later.
