About Moss Boss
Exterior cleaning done right, every single time.
For more than ten years, Moss Boss has been the name South Coast homeowners trust when their roof, siding, or walkways need real attention. We built this company on craftsmanship, honest pricing, and a refusal to cut corners.
Every job begins with a careful inspection and a soft wash approach — the same method recommended by roofing manufacturers for asphalt, cedar, and slate. No blasting. No damage. Just a gentle, eco-safe solution that breaks moss, algae, and mildew down at the root.
What We Clean
Three specialties.
One uncompromising standard.
Roof Cleaning
Soft wash treatment that lifts black streaks, moss, and lichen from asphalt, cedar, and slate — backed by a two-year clean guarantee.

House Washing
Vinyl, fiber cement, brick, stucco, and cedar — cleaned with low-pressure rinses and an eco-safe solution that leaves the finish intact.

Misc. Cleaning
Walkways, patios, decks, fences, gutters, and outdoor furniture — the in-between projects most contractors won't touch.
View ServiceThe Soft Wash Method
Our soft wash method protects your home.
A precise three-stage protocol — quiet, controlled, and engineered to protect every surface it touches.
Inspect & Assess
We walk the property with you, identify problem zones, and tailor the treatment to the surface type, age, and condition of every area we'll clean.
Apply Eco-Safe Solution
Our biodegradable cleaning solution is gently applied at low pressure. It breaks the bond between organic growth and your surfaces in minutes, with no harm to your home, plants, pets, or family.
Rinse & Reveal
A controlled, low-pressure rinse carries everything away and reveals the surface beneath. The result is uniform, complete, and built to last for years.
