Keep rain where it belongs—away from your roof, walls, and foundation. 123 Exteriors clears gutters and downspouts end-to-end so water flows freely and your home stays protected.
Clogs don’t just look bad—they cause expensive problems fast:
Foundation erosion & cracks from water pooling around your home.
Roof leaks & rot when water backs up under shingles.
Ruined landscaping from overflow washing out beds and soil.
Basement leaks/flooding when water isn’t routed away.
We specialize in safely removing moss, algae, and debris from all roof types, including asphalt shingles, wood shakes, metal roofing, and clay tiles.
Before addressing moss growth, we clear away loose debris, such as leaves, twigs, and branches, that can accumulate on your roof and in gutters. This prevents drainage issues and prepares the surface for deep cleaning.
Depending on your roofing material, we carefully remove large moss patches using gentle scrapers and stiff-bristle brooms to avoid damaging shingles or tiles while ensuring maximum moss removal.
To prevent moss from returning, we apply a biodegradable moss-be-gone solution made from a safe mix of bleach, dish soap, vinegar, and water. This treatment kills any remaining moss spores and slows down future growth.
Smart roof check-up: We inspect for moss, algae, soft spots, and drainage issues so we treat exactly what your roof needs.
Gentle, effective cleaning: Safe, roof-friendly techniques lift moss and grime without harming shingles or landscaping.
Targeted de-mossing: We clear growth at the roots and treat regrowth areas to help slow it from coming back.
Rinse & review: A careful rinse, final inspection, and simple care tips to keep your roof in top shape.
"Competitive pricing and easy to work with; Andre has helped me with a few projects and I’m happy to continue to work with him."
"When we were listing our house for sale, Andre and his team did an excellent job of cleaning up the large area of interlocking brick in our yard and driveway. The work was fast and thorough, and the place looked amazing afterward! They also cleaned up everything before they left, including washing down the siding to make sure any splashback on the house was dealt with. I highly recommend this company!"
