Soft Washing: Chemistry,
Not Pressure.
Low-pressure biocide cleaning that kills algae and mold at the root — safe for roofs, siding, and screens, and the only method roofing manufacturers approve. Results last 3–5x longer than pressure washing.

The Method
What Is Soft Washing?
Soft washing cleans exterior surfaces with biodegradable biocide solutions applied at very low pressure — 100–500 PSI on roofs, never more than 500 PSI on siding. That's roughly the force of a garden hose. Instead of blasting stains off with water, the solution kills the organisms causing them: Gloeocapsa magma (the black algae streaking Tampa Bay roofs), mold, mildew, lichen, and bacteria.
Pressure washing works the opposite way — 1,500–4,000 PSI of raw force. That's the right tool for concrete driveways and sidewalks, but on a roof or siding it strips shingle granules, cracks tile, tears screens, blows out stucco, and drives water behind siding seams. Worse, it only removes the growth you can see. The roots survive, and the stains return in months.
Because soft washing kills growth at the root, roofs stay clean 18–36 months and house exteriors 12–24 months — typically 3–5x longer than a pressure rinse. In Tampa Bay's year-round humidity, that difference is the whole ballgame.
Warranty-Safe
The Only Manufacturer-Approved Way To Clean A Roof
This isn't marketing — it's written into the warranty paperwork. High-pressure cleaning voids most shingle and tile warranties. Low-pressure soft washing preserves them.
- ARMA — Asphalt Roofing Manufacturers Association
- GAF (asphalt shingle manufacturer)
- Owens Corning (asphalt shingle manufacturer)
Source: GAF Technical Bulletin R-102, “Algae Staining on Shingled Roof Surfaces” — GAF and ARMA both specify low-pressure cleaning and caution that pressure washing can dislodge granules and void shingle warranties.
The same logic applies beyond the roof: screen manufacturers void warranties over pressure-washed mesh, and stucco can't take PSI above 500 without water intrusion risk. Sandbar Soft Wash soft washes Tampa Bay roofs, siding, and pool cages the warranty-safe way.

Soft Washing vs Pressure Washing
| Soft Washing | Pressure Washing | |
|---|---|---|
| Pressure | 100–500 PSI | 1,500–4,000 PSI |
| How it cleans | Biocide chemistry kills growth at the root | Force blasts growth off the surface |
| Best for | Roofs, siding, stucco, screens, gutters, painted wood | Concrete driveways, sidewalks, pool decks |
| Roof warranty | Preserved — ARMA/GAF/Owens Corning approved | Voided on most shingle & tile roofs |
| Results last | 18–36 months (roof) · 12–24 months (house) | Months — roots survive and regrow |
| Surface risk | None when done correctly | Stripped granules, cracked tile, torn screens |
We run both systems on every truck. Your roof gets soft wash chemistry; your driveway gets a high-PSI surface cleaner. Right method, right surface, every time.

Questions
Soft Washing FAQs
What is soft washing, exactly?
Soft washing is a low-pressure cleaning method that uses biodegradable biocide solutions — applied at 100–500 PSI, about the force of a garden hose — to kill algae, mold, mildew, and bacteria at the root. Pressure washing relies on 1,500–4,000 PSI of raw force; soft washing relies on chemistry. That is why results last 3–5x longer and why it is safe on roofs, siding, and screens.
Is soft washing safe for my roof?
Yes — it is the only method that is. Soft washing at 100–500 PSI is the sole cleaning technique approved by ARMA (the Asphalt Roofing Manufacturers Association), GAF, and Owens Corning. Pressure washing a roof strips shingle granules, cracks tile, and voids most manufacturer warranties.
How long do soft washing results last?
Roofs typically stay clean 18–36 months after a professional soft wash; house exteriors 12–24 months. Because the solution kills growth at the root instead of rinsing it off the surface, regrowth is far slower than after a pressure rinse. Shaded, north-facing, or waterfront surfaces regrow faster.
How much does soft washing cost in Tampa Bay?
It depends on the surface, size, and condition — roof, house, and pool cage each price differently. Send your address for your instant price at sandbarsoftwash.com/instant-quote — no on-site visit needed to get started.
Is the soft wash solution safe for plants, pets, and pools?
Yes. We use professional-grade biodegradable solutions, rinse plants with fresh water before and after treatment, and follow strict containment around pools. Water your landscaping the morning of service for added protection.
Soft washing vs pressure washing — which does my home need?
Both, usually — on different surfaces. Roofs, siding, stucco, and screen enclosures need soft wash chemistry. Concrete driveways, sidewalks, and pool decks handle high-PSI surface cleaning well. We match the method to each surface on every job instead of blasting everything with one machine.
