Roof cleaning in Rocklin
The streaks are algae, and pressure is the wrong answer
Cable Pressure Washing and Solar Panel Cleaning takes roof cleaning requests across Rocklin as part of our Placer County roof cleaning service. A trusted local roofing partner does the roof work, and you get one quote from Cable. We are based here, so we know the local roofs: concrete tile in the newer neighborhoods, composition shingle in the older ones, and black streaks creeping across both.
Those streaks are organic growth, a roof algae called Gloeocapsa magma, and they will not rinse off in winter rain. Getting rid of them the wrong way costs more than leaving them alone. Here is the right way, and what it costs.
The method
Soft wash only. Never high pressure.
A roof is the one surface where pressure washing does real damage. High pressure strips the protective granules off asphalt shingles and can crack concrete and clay tile, and either one shortens the life of the roof you are trying to protect. That is why a roof should get a soft wash: a low-pressure cleaning solution that kills the algae, moss, and lichen instead of blasting at the stains they leave. When moss is the main event, our roof moss removal page covers the hotter mix, the timeline, and what to expect.
Because the treatment attacks the growth itself, the roof does not just look better, it stays cleaner longer than a surface-level rinse could manage. The full method, and the science behind why the streaks keep coming back on untreated roofs, is covered on our roof cleaning service page and in the black streaks on roof guide.

Local knowledge
Rocklin's two roofs: tile and shingle
Drive through Rocklin and you see the same two roofs over and over. The newer neighborhoods, Stanford Ranch and Whitney Ranch especially, are concrete tile almost wall to wall. The older streets around Sunset Whitney lean composition shingle. Both grow the same black streaks, because Gloeocapsa magma does not care what it lives on, and both take the same cure.
Concrete tile
Tile shrugs off sun but holds organic growth in its channels and overlaps, and walking a tile roof carelessly cracks tiles. A soft wash keeps both the pressure and the foot traffic to the minimum the job actually needs.
Composition shingle
Shingle roofs show streaks sooner and darker, usually on the north-facing slope where moisture lingers after our foggy valley mornings. The granule surface is exactly what high pressure destroys, which is why the soft wash matters most here.
While we're here
Gutters are the natural add-on
Our own crew handles gutter cleaning, and it pairs well with a roof cleaning. Gutter cleaning runs $1.00 per linear foot on single-story homes and $2.00 per linear foot on two-story homes with a $200 minimum, covered in detail on our gutter cleaning in Rocklin, CA page. And if the faces of your gutters carry black tiger stripes that a wash will not lift, that is oxidation. Gutter brightening removes it, quoted as a discounted add-on when our crew is already on site for your gutters. Honest test first: if the striping comes off with a normal wash, we tell you to skip the brightening.
Who you're hiring
Insured, honest about scheduling, local
For exterior cleaning work in California no contractor license is required, so the words that actually protect you are the insurance ones. Cable carries liability insurance on every job. We are a father-and-son business based in Rocklin, and your quote arrives in writing before any work starts.
Maintenance matters too. A roof that gets cleaned before moss roots deep and before roof debris packs the valleys is a roof that needs less of everything later, which is the honest version of curb appeal: protection first, looks second. Our Rocklin seasonal cleaning calendar shows where roof care fits in the year.
