Don’t Let a Dirty Roof Damage Your Home—Let’s Wash It Right

A dirty roof doesn't just hurt curb appeal—it can quietly damage your home. Over time, buildup from algae, mold, and grime breaks down your shingles and shortens your roof’s lifespan. At Exterior Prowash, we help Chapel Hill homeowners protect their property and restore its beauty with gentle, eco-safe roof cleaning that gets real results without causing harm.

What Roof Cleaning Does for Your Home

Roof cleaning is more than cosmetic. It safely removes harmful growth like algae, black streaks, and moss that damage your roof over time. We use a soft washing process, not high pressure, to clean without stripping shingles or cracking tiles—leaving your roof looking better and lasting longer.

Roof Types We Clean Safely and Thoroughly

Not all roofs are created equal. We adjust our cleaning methods to protect the material and integrity of each surface.

Metal Roofs

Our team removes oxidation, mold, and debris while preserving the finish. No dents, no damage—just a refreshed, clean surface.

Shingle Roofs

Asphalt shingles are vulnerable to granule loss under high pressure. We use a gentle, soft wash that safely removes stains and buildup.

Why Regular Roof Cleaning Matters

Routine cleaning isn’t just maintenance—it’s protection.

  • Prevents water damage
  • Extends the lifespan of your roof
  • Removes harmful algae, mold, and moss
