Mould, algae, pollution and years of grime come off a house with the right chemistry and the right pressure, which is usually much less pressure than people expect. We soft wash roofs, siding, stucco and brick, pressure wash concrete and decks, and clean commercial facades and parking areas, with the method matched to the surface so nothing is stripped, etched or forced behind the siding.
Four kinds of cleaning, each with its own pressure and chemistry.
Shingle, tile and flat roofs cleaned with low pressure and the right solution; never a pressure wand on shingles.
Surfaces and methods →
Green algae and grey grime off the north side; mildew out of stucco; brick cleaned without etching the mortar.
Surfaces and methods →
Pressure washing where the surface can take it, with surface cleaners for an even finish and no stripes.
Surfaces and methods →
Building exteriors, storefronts, dumpster pads and lots cleaned off-hours with reclaim where needed.
Soft wash vs pressure →High pressure cleans concrete and ruins a roof. These are the surfaces we clean and how.
What: black streaks (algae), moss and lichen that lift the shingles and hold water.
How: a sodium hypochlorite solution applied at garden-hose pressure, allowed to work, rinsed. Pressure washing strips granules and voids warranties.
Every 3–5 yr, or as neededWhat: green algae, mildew, chalk and spider webs, worst on the north and shaded sides.
How: house-wash solution applied low and rinsed top-down so nothing is forced up behind the laps.
Every 1–2 yrWhat: mildew in the texture, pollution, efflorescence, rust stains.
How: surface-specific cleaners, low pressure, never a tight nozzle on mortar joints or soft stucco. Before any coating or painting.
Before every recoatWhat: driveways, walkways, patios, pool decks, parking lots, oil and rust stains.
How: 3,000+ psi with a rotary surface cleaner for an even finish; degreaser on oil; polymeric sand and sealer on pavers if you want it.
Every 1–2 yrWhat: grey weathered wood, mildew, old stain.
How: cleaner and brightener at low pressure so the grain is not furred, dried, then stained or sealed by our painters.
Before every re-stainWhat: black tiger stripes on gutters, dirt on soffit and fascia, debris and algae on flat roofs.
How: soft wash with a gutter brightener; flat roofs cleaned as the first step of every coating job.
With maintenance visits
A rented pressure washer cleans a driveway and damages almost everything else: it strips shingle granules, forces water behind siding, furs wood and etches mortar. Soft washing kills the growth so it rinses away and stays away longer.
Cleaning as an early damage identification system, then repairs, sealing or a complete new surface, depending on what the wall needs.
Best for: Immediate maintenance: stop active leaks and clean the building's exterior
Best for: Buildings that need lasting protection against weathering
Best for: A full exterior renovation with the strongest moisture defence

Every surface identified and the method and chemistry chosen for each; delicate areas, plants and fixtures noted. Free, with a written scope.
Windows, doors, landscaping and electrical covered or pre-wetted, neighbours told, equipment and solutions set up for each surface.
Soft wash and pressure wash in the right places, top-down, each area checked for even results and surface protection. Most homes in a day.
A walkthrough with you, plants rinsed again, and a note of anything we saw on the roof or walls that needs more than cleaning.
Square footage, storeys, how heavy the growth is and the surfaces involved decide the price. These are honest ranges from our own jobs; your written estimate is free and exact.
A wash is the first step of every coating, painting and staining job and of our maintenance plans. Bundle the roof and house wash with a gutter clean or a maintenance visit and the trip is shared.

Concrete, pavers, stone patios, fences and decks with the pressure turned down. Siding, stucco, brick, painted surfaces and especially roofs are soft washed: the cleaning is done by the solution, and the water pressure is little more than a hose.
Yes, done our way. Vinyl, wood, stucco and fiber cement each get their own pressure and cleaner, and the rinse runs top-down over the laps. High pressure aimed up at siding forces water behind it and that is the damage we get called to fix.
Yes, by soft washing only. The black streaks are algae and the moss is lifting the shingles; a low-pressure solution kills both and the rain finishes the rinse. A pressure washer on a shingle roof strips granules and voids the warranty, so we do not do it.
Once a year for most homes, more under heavy tree cover or on a shaded north side; roofs every three to five years. Before any painting, staining or coating, always.
We use biodegradable, surface-safe detergents, pre-wet and rinse plants and lawns, and direct run-off away from drains and reclaim it where regulations require.
Both use high-pressure water; power washing heats it for grease, gum and oil on commercial concrete. Neither belongs on a roof or siding, which is what soft washing is for.

"They repointed my brick chimney and repaired stucco trim in Wyckoff using breathable mortar and elastomeric coating, and power washed the exterior. The crisp finish looks brand-new."
"Roof4Roof was very professional, the employees were courteous and respectful with my property. The job was completed on time. All debris was cleaned and removed from the job site. We would not hesitate to recommend Roof4Roof."
"Work was done on time as promised. The staff was very polite and professional. Work area was left very clean and neat. I had no problems with this project, they handled everything."
A share of every job funds a roof, a repair or a home for a family in need, in New Jersey and abroad: $1.5M+ donated and 1,300+ families helped since 2010.
