What is A Roof Wash?
Roof washing is the process of removing harmful organic growth—such as mold, algae, and mildew—that eats away at your shingles.
To do this safely, we use a technique called Soft Washing. Instead of using high pressure that can damage your roof, we apply a specialized cleaning solution that kills the bacteria at the root.
This gentle, effective method is the industry standard and is officially recommended by the Asphalt Roofing Manufacturers Association (ARMA)
Why do i need it?
Those unsightly black streaks on your roof aren’t just dirt—they are actually a living bacteria called Gloeocapsa Magma.
If left untreated, this algae feeds on the limestone filler in your asphalt shingles, causing them to lose their protective granules, become brittle, and deteriorate years before they should.
Beyond the structural risks, a dark, stained roof absorbs significantly more heat, which can spike your cooling costs during the summer.
We use a specialized soft wash technique to gently neutralize this growth at the root—removing the stains instantly and preserving the integrity of your shingles without the risk of high-pressure damage.

At Driftless Softwash & Pressure Wash, our confidence comes from specialization. We are not a “jack-of-all-trades” company; instead, we strictly limit our services to the specific exterior cleaning methods we have mastered.
We believe in quality over quantity, which means we will never take on a project unless we are fully trained, equipped, and experienced in that specific area. This disciplined approach ensures that your home is always in safe, expert hands.
Furthermore, we stand behind our work long after the truck pulls away. If you have any concerns, just give us a call or text—we are happy to return and re-inspect your home within a few weeks of completion to ensure the clean meets your standards and ours.
How Much Will A ROOF Wash Cost?
One of the most common questions we get at Driftless Softwash & Pressure Wash is about the price of a roof cleaning.
While we wish we could give a single flat rate for every home in the La Crosse area, the truth is that every roof is unique.
On average, most professional soft wash roof cleanings range between $500 and $1,300, but this can vary based on a few key factors:
Surface Area: Naturally, a larger roof requires more cleaning solution and time.
Pitch & Accessibility: Steep peaks or multi-story homes often require additional safety measures.
Severity of Growth: A roof with light black streaks is faster to treat than a roof with thick, established moss.
It is important to remember that this isn’t just a cosmetic expense; it’s an investment in your home’s longevity. A professional soft wash costs a fraction of the price of a premature roof replacement. Curious about where your home falls on that scale?
