A roof soft-wash in Concord, NC — same week, same angle.

The stains you're seeing

It's not dirt — it's living organisms eating your home.

Those black streaks on your shingles, the green haze on your north-facing siding, the orange splash under the hose bib — they're colonies of algae, mold, mildew, and bacterial rust. Left alone, they shorten roof life, void shingle warranties, and quietly cost a Carolina homeowner $6,000–$18,000 in premature exterior replacement.

Black streaks on the roof

Gloeocapsa magma — a cyanobacteria that feeds on the limestone filler in asphalt shingles. It travels roof-to-roof on the wind and shows up first on the north side. It's not cosmetic: it traps heat, ages shingles, and is the most common reason a 20-year roof fails at year 12.

Green algae on siding

The dark green film on HardiePlank, vinyl, and painted wood isn't dust — it's Chlorococcum and mildew colonies eating the paint film from the outside in. Power-washing strips the paint. Soft-wash chemistry kills the colony at the root so regrowth takes 4–6× longer.

Orange & black on concrete

Driveways and pool decks collect two stains at once: iron bacteria rust (the orange splatter from irrigation) and black mildew in the shade bands. Both create slip hazards and HOA violation notices — and both lift completely with the right surfactant blend, no surface scarring.

The bad news: these organisms never wash off with a garden hose. The good news: a single soft-wash treatment typically holds them off for 2–3 years on siding and 24+ months on residential roofs — backed in writing.

The method

Why pressure washing is the wrong tool — and what a certified soft-wash actually does differently.

A pressure washer is a 4,000 PSI garden hose. It's great for concrete, terrible for everything else. Soft-wash chemistry does the opposite: low pressure, high dwell time, and a biodegradable solution that kills the organism so it can't come back next season.

Familiar

Pressure washing

High PSI · Water only · Surface contact

  • Blasts algae loose — does not kill it. Regrowth in 6–10 months.
  • Forces water under shingle tabs and behind vinyl seams, voiding roof warranties.
  • Strips oxidation from aluminum siding and etches concrete.
  • Strips paint from wood, fiber cement, and trim in a single pass.
  • No chemistry = no residual protection. The biofilm returns first.
  • Risk of landscape damage and broken window seals from operator error.
The verdict

"Pressure washing is the sledgehammer. Soft-wash is the surgeon's scalpel. They both finish the job — one of them also finishes your roof."

— Capt. James Redding, founder

Certified soft-wash

Low PSI · EPA Safer Choice chemistry · Deep contact

  • Applies a metered sodium-hypochlorite / surfactant blend at 40–80 PSI (below garden-hose pressure).
  • Kills algae, mold, mildew, and bacterial spores at the root — typically 6× longer-lasting than pressure washing.
  • Safe on asphalt shingles, painted wood, vinyl, HardiePlank, EPDM, and stucco.
  • No water forced under seams, no shingle granule loss, no oxidation stripped.
  • Pet-safe and plant-safe on every residential job — pre-wet, cover, and neutralize per SW-7 protocol.
  • Backed by a 24-month no-regrowth warranty on residential asphalt shingle roofs.
  1. Step 1

    Property walk & photo estimate

    We photograph every surface and deliver a fixed quote within ~4 hours during business hours.

  2. Step 2

    Pre-treat landscape & water sources

    Plants, irrigation heads, and ponds are pre-wet and covered. Downspouts are diverted.

  3. Step 3

    Metered soft-wash application

    SW-7 certified crew applies the chemistry at low pressure with calibrated dwell time.

  4. Step 4

    Gentle rinse & neutral rinse

    Surfaces receive a controlled freshwater rinse followed by a neutralizing rinse on landscape zones.

  5. Step 5

    Walkthrough & warranty card

    You walk the job with the crew lead. Residential roof cleanings leave with a 24-month warranty card.

Our origin

Founded by a retired Charlotte fire captain who treated the trucks the same way — and now treats your home the same way.

In 2014, Captain James Redding retired from the Charlotte Fire Department after 31 years and one simple question from a neighbor: "If my driveway is as black as a soot-covered engine, why won't a pressure washer bring it back?" The answer — that what looked like dirt was living biofilm — sent James and his wife Marisol to SoftWash Systems training in West Palm Beach.

They brought the same discipline back: pre-incident planning on every property, calibrated chemistry instead of guesswork, and a written checklist for every crew on every job. The trucks are gone. The standards aren't.
