Pressure Washing Roseville for Slick Walkways, Black Streaks and Downspout Stains

What we wash

What does a wash cover on a Roseville home?

A wash covers the hard surfaces around the house: the driveway, front walk, side yards, patio and the splash zone under each downspout. We offer it as an add-on to gutter cleaning and downspout clearing across Roseville, CA and nearby Placer County, in ZIP codes 95661, 95678 and 95747. The wash is quoted with the cleaning, on the call.

Each part of town has its own problem. North-facing walks under the oaks in Diamond Oaks and near Royer Park stay damp all winter and turn green and slick. Sun City Roseville patios collect grit that washes off concrete tile roofs. In Westpark and Fiddyment Farm, newer driveways pick up tire marks and dust from nearby building sites. See every neighborhood we cover.

• Driveways and walkways cleared of algae, dirt and tire marks
• Patios and pool decks washed with a surface cleaner for an even finish
• Downspout splash zones, where dark streaks build up on concrete and stucco
• Gutter faces soft washed to lift the gray streaks on the outside

Surface by surface

Which surfaces get power washing in Roseville, and which don't?

Concrete gets real pressure. Stucco, paint and wood get a soft wash or a low, wide spray. Roofs, windows and solar panels get no pressure washer at all. Matching the method to the surface is the whole job, because the wrong nozzle can etch concrete, gouge wood or crack a tile.

Surface	Method	Why
Concrete driveway, walks, patio	Pressure wash with a surface cleaner	Lifts algae, dirt and tire marks evenly
Pavers and stamped concrete	Low pressure, wide fan tip	High pressure strips sealer and blows out joint sand
Stucco walls	Soft wash	Low pressure and a mild cleaner, no gouges
Painted siding and trim	Soft wash	Keeps paint on the wall
Wood deck or fence	Low pressure or soft wash	Strong spray raises the grain
Concrete tile roof	Skip	Tiles crack underfoot; a tile roofer's job
Asphalt shingle roof	Skip	High pressure damages shingles
Windows, screens, solar panels	Skip	Water gets forced past seals and frames

Concrete that takes full pressure

Plain broom-finish concrete is tough. A spinning surface cleaner holds the spray at one height, so you don't get the stripes a hand wand leaves. Oil spots get a degreaser first and may fade rather than vanish.

Stucco, paint and trim

Most Roseville homes have stucco walls. A hard jet can chip the finish and drive water into cracks. A soft wash uses a mild cleaner at low pressure, then a gentle rinse. It follows the EPA's advice for mold on hard surfaces: detergent and water, then let it dry fully.

Wood decks and fences

Redwood and cedar are soft. A low, wide spray held at a steady distance cleans without tearing the fibers and leaving the wood fuzzy.

Tile and shingle roofs: no pressure washer

We never pressure-wash a tile or shingle roof, and we don't walk on concrete tile. The Asphalt Roofing Manufacturers Association says high-pressure washing is likely to damage asphalt roofing. Eagle Roofing, a concrete tile maker, says to hire a roofing contractor with tile experience to clean a tile roof.

What causes the black streaks?

On shingle roofs, the dark streaks are mostly an algae called Gloeocapsa magma, per the same ARMA page. On walks and walls, green film grows where shade and rain keep the surface wet. Almost all of Roseville's rain falls from October to April (WeatherSpark), so late spring is a good time to wash it off.

Gutters first

Why should the wash come after the gutters are cleaned?

Cleaning the gutters drops debris and dirty water onto the walls and walks below. Wash the patio first and the gutter work stains it again. So the crew clears the gutters, flushes and tests each downspout, and only then washes the ground. It is the same top-down order as the rest of our visit, step by step.

Many dark stains on concrete also come from a downspout that dumps water in one spot. If it is plugged or missing its extension, the stain comes back after the next storm. That's why the crew will flush and test the downspouts before any power washing in Roseville starts.

Booking pressure washing in Roseville, CA with a gutter visit

One trip, one crew, one quote. The wash is priced with the gutter cleaning on the call, based on the surfaces and their size. If the same walk keeps staining because gutters under heavy oaks overflow, ask about guards that keep leaves out. Our guide to the trees that fill local gutters covers the oaks and pines that drop the most.

Wash water rules

Where does the wash water go in Roseville?

Not into the storm drain. The City of Roseville's surface washing rules say wash water “may not be discharged to the City's stormwater drainage system.” Small amounts may soak into a lawn or gravel area.

Storm drains empty to local creeks, and the City notes that Roseville creeks host salmon and steelhead spawning grounds. Storm drain systems are regulated under the federal Clean Water Act through the State Water Board's storm water program. On your job, that means:

1. Sweep first, as the City asks, before any water goes down.
2. Block the curb drain near the driveway.
3. Use plain water where it will do, since the City asks for no soap when possible.
4. Send rinse water to the lawn or beds, not down the curb to the street.
