ExploreMore than clean — protected
Those black streaks and green patches are living algae and moss feeding on your roof. We never blast a roof with high pressure — we use a low-pressure soft wash with professional treatments that kill the growth at the root, rinse it clean, and keep it from coming back. Safe for asphalt shingle, concrete and clay tile, and flat roofs alike.
Protects the roof
Moss and algae trap moisture and degrade shingles — removing them extends roof life and protects your investment.
No pressure, no damage
We never power-wash a roof; soft-wash chemistry does the work so your shingles and tile stay intact.
Curb appeal restored
A clean, streak-free roof instantly makes the whole house look maintained and newer.
Simple, thorough, and respectful of your home

Conejo Valley homeowners trust us
“We had them do the windows, gutters, and wash the whole house in one trip. They showed up right on time and the stucco honestly looks brand new. So nice not having to call three different companies.”
“Not a streak anywhere, and they got the screens and those grimy little window tracks too. They were really careful moving things around inside. Huge difference.”
“My driveway had oil stains from years ago that I figured were permanent. Nope — almost all gone. They knew which spots to go easy on so nothing got damaged.”
Roof Cleaning FAQs
Will roof cleaning damage my shingles or tile?
No. We never use high pressure on a roof — that strips granules and cracks tile. We use a low-pressure soft wash with professional treatments that kill moss and algae and rinse clean, the method shingle manufacturers and the ARMA recommend.
What are the black streaks on my roof?
Those are algae (Gloeocapsa magma) feeding on the limestone filler in shingles. Our soft-wash treatment kills it at the root, so the streaks clear and stay gone far longer than a quick rinse.
How much does roof cleaning cost?
Roof soft-washing typically starts around $450 and depends on roof size, pitch, type, and how much growth there is. We give a free, no-obligation quote up front.
How often should a roof be cleaned?
Every 1–2 years for most SoCal homes — sooner if your roof is shaded by trees or you already see moss or streaking.
