Softwash Roof Cleaning & House Washing

What Is Softwashing?

Softwashing is a low-pressure cleaning method that uses biodegradable cleaning solutions to kill and remove biological growth — algae, mold, mildew, moss, lichen, and bacteria — from your roof and home exterior. Unlike pressure washing, softwashing uses water pressure no higher than a standard garden hose, making it safe for asphalt shingles, wood, vinyl, stucco, brick, and virtually all exterior surfaces.

The cleaning solution does the work, not the pressure. This means no blown-off granules, no cracked shingles, no damaged mortar — just a thorough, lasting clean that extends your roof and exterior's life.

Roof Softwashing

Roof softwashing is the only manufacturer-approved method for cleaning asphalt shingle roofs. The Asphalt Roofing Manufacturers Association (ARMA) specifically recommends low-pressure chemical cleaning over pressure washing, which can void shingle warranties and cause immediate granule loss.

Oklahoma homes are particularly susceptible to Gloeocapsa Magma — the black algae that creates dark streaking across roof surfaces. Our softwash treatment eliminates it completely, with results that typically last 2-5 years. We also treat for moss and lichen, which if left untreated, will penetrate and lift shingles causing accelerated deterioration.

What Roof Softwashing Removes

• Black streaks — Gloeocapsa Magma algae (the most common roof stain in Oklahoma)
• Moss — holds moisture against shingles, causing rot and lifting
• Lichen — the hardest to remove; etches into shingles if left too long
• Mildew and mold — can spread to soffits, fascia, and attic if untreated
• Green algae — common on north-facing slopes and shaded areas

House Washing

Our softwash house washing service cleans the entire exterior of your home — siding, brick, stucco, gutters, fascia, soffits, windows (exterior), decks, fences, and driveways. We use the appropriate solution and pressure for each surface type, ensuring a thorough clean without any damage risk.

House washing dramatically improves curb appeal, removes years of oxidation and biological growth, and is often recommended before exterior painting or before putting a home on the market. A clean exterior can meaningfully affect a home's perceived value.

Surfaces We Softwash

• Asphalt shingle roofs
• Metal roofs (low pressure, specialized solution)
• Vinyl siding
• Brick and mortar
• Stucco and EIFS
• Wood siding and cedar shake
• Fiber cement (HardiePlank and similar)
• Gutters and downspouts
• Soffit and fascia
• Concrete driveways and walkways
• Wood decks and fences

Why Softwash Instead of Pressure Washing?

Pressure washing at high PSI will remove biological growth temporarily — but it also removes granules from asphalt shingles (accelerating aging), can crack or loosen mortar, can force water under siding, and does nothing to kill the organisms causing the staining. They grow back quickly because the roots were never treated, just blasted off.

Softwashing uses biodegradable biocides that kill the organisms at their root. The visual result is the same — or better — and the clean lasts dramatically longer. It is the professional standard for roof cleaning and is what your shingle manufacturer recommends.
