YOUR LOCAL CHOICE FOR
ROOF CLEANING IN SOUTHERN CALIFORNIA
Those black streaks running down your roof are not dirt, they are Gloeocapsa magma, an algae that feeds on the limestone filler in modern shingles. The SoCal marine layer and morning dew give it exactly the moisture it needs to spread, and once it is established, it shortens the life of your roof by holding moisture against the granules.
We do not pressure wash roofs. High pressure strips the granules right off the shingle and voids the manufacturer warranty. Instead, we apply a specialized roof treatment that kills the algae, moss, and lichen at the root, and the rain rinses the dead growth away over the following weeks. Your roof is cleaned without a single granule lost.
If your roof has those dark streaks or green patches, call (562) 526-0639. We will come out, tell you what it needs, and give you a clear price.
EVERY ROOFING MATERIAL, SAME SAFE TREATMENT
From concrete tile to asphalt shingle, every roof in SoCal needs a different approach. We never use high pressure on any of them.
Asphalt Shingle Roofs
The most common roof across LA and Orange County. We apply a non-pressure chemical treatment that kills the algae and moss at the root. No granules lost, no warranty voided. The black streaks fade as the dead organism breaks down and washes away with the rain.
Concrete & Clay Tile Roofs
Tile roofs are durable but the concrete and clay are porous, which means algae and moss root deep into the surface. We treat the tile with a solution that kills the growth, and we inspect every tile for cracks or slips while we are up there.
Flat & Low-Slope Roofs
Common on commercial buildings and modern SoCal homes. These roofs hold standing water and debris, which accelerates organic growth. We clear the debris and treat the surface to prevent the algae and mold from compromising the membrane.
