    Soft washing is what you use when pressure is the problem rather than the solution. Instead of forcing water at a surface, it applies a cleaning solution that kills the organic growth at the root, then rinses gently. It is slower, it costs about the same, and on the wrong surface it is the only method that will not cause damage.

    What soft washing actually involves

    The solution does the work. I apply a biodegradable detergent blend matched to the surface and the growth, let it dwell for the time it actually needs, then rinse at pressures closer to a garden hose than a pressure washer. Because the treatment kills the algae and mildew rather than just knocking the visible layer off, results last considerably longer than a pressure rinse before regrowth becomes visible.

    Why it matters

    High pressure on the wrong surface causes damage that is expensive and sometimes impossible to reverse. On asphalt shingles it strips the protective granules and voids most manufacturer warranties. On stucco and EIFS it forces water behind the system and into the wall assembly. On aged painted siding it takes the paint off. On soft old mortar it blows the joints out. Soft washing exists specifically because these surfaces still need cleaning and cannot survive the alternative.

    The Process

    How it works

    Straightforward. No hidden fees, no bait-and-switch.

    01

    Surface + Growth Assessment

    I identify what is actually growing and what the surface can tolerate, then mix the solution to the right dilution for that combination.

    02

    Apply + Dwell

    Solution goes on at low pressure and is left to work for the full dwell time. This is the step most operators cut short, and it is the reason their results do not last.

    03

    Gentle Rinse + Protect

    Low-pressure rinse carries the dead organic matter away. Landscaping is pre-rinsed beforehand and flushed again afterward.

    Soft washing is the difference between cleaning a roof and shortening its life. The ARMA (Asphalt Roofing Manufacturers Association) recommends soft washing for shingles, and pressure damage voids most manufacturer warranties. I would rather talk you into the method your surface needs than take the faster job and leave you with a problem later.
