Roof Cleaning in LA County
Roof Cleaning
Soft-wash removal of moss, algae, and black streaking without tearing up your shingles.
Those dark streaks running down a roof are not dirt. They are algae feeding on the limestone filler in asphalt shingles, and the moss that follows lifts shingle edges and holds water against the deck. We soft-wash roofs, which means low pressure and the right cleaning solution rather than a pressure washer that would strip granules and shorten the roof's life.
Why it matters
Moss holds moisture against the roof deck and works its way under shingles, which is how small problems turn into leaks and rot. Algae streaking also darkens the roof so it absorbs more heat. A roof is one of the most expensive things on a property, and cleaning it is a fraction of replacing it early.

Our process
How we handle Roof Cleaning
Protect the property
Plants, landscaping, and anything nearby get covered or pre-wetted before we start so runoff does not cause damage.
Soft wash
Low-pressure application of a cleaning solution that kills moss and algae at the root rather than blasting the surface. No pressure washing on shingles, ever.
Rinse and clear
The roof is rinsed down, gutters are flushed of anything we knocked loose, and surrounding areas are washed off.
Good to know
Roof Cleaning questions
It would, which is exactly why we do not do it on shingles. High pressure strips the protective granules and takes years off the roof. We soft-wash instead.
Eventually, since spores are always in the air, but a proper treatment kills it at the root so regrowth is slow. Shaded and north-facing roofs come back fastest.
We cover and pre-wet landscaping before starting and rinse everything afterward. Tell us about anything especially delicate and we will take extra care with it.
