Roof Cleaning in Springdale, AR
Those dark gloeocapsa stains creeping across north-facing shingles come from airborne algae thriving in the region’s humidity, and they need a no-pressure soft wash to kill the organism, not a pressure wand that strips granules.
Those black streaks running down your shingles are not dirt or mildew you can hose off. They are Gloeocapsa magma, a cyanobacteria that feeds on the limestone filler manufacturers add to asphalt shingles. It spreads spore to spore, which is why streaking always starts on the north and shaded slopes that stay damp longest. Left alone, the colony holds moisture against the shingle mat and accelerates aging.
The only correct method on asphalt shingles is a soft wash, which is the approach the Asphalt Roofing Manufacturers Association (ARMA) endorses. We apply a controlled sodium hypochlorite solution that kills the organism at the root, dwell it, then rinse at garden-hose pressure. Pressure washing a roof is never acceptable. The blast strips the ceramic-coated granules that protect the asphalt from UV, voids most shingle warranties, and can drive water under the courses. Once granules are gone, the substrate cooks and fails years early.
Moss and lichen are a tougher problem than algae. Moss roots into the shingle seams and lifts the edges; lichen bonds to the granule surface like a barnacle. Both get treated chemically and are allowed to die and release over following weeks rather than being scraped, since scraping tears granules off with them.
A proper soft wash also protects landscaping with pre-wet and rinse, and accounts for runoff. Done right, it kills the colony, restores the roof’s appearance, and adds years before replacement, all without touching the warranty.
Roof Cleaning in Springdale & Washington County
Springdale straddles the Washington-Benton county line in the heart of Northwest Arkansas, about two and a half hours northwest of our Conway base. It’s home to Tyson Foods’ corporate headquarters, and the poultry industry shapes the whole region, from the processing plants along the rail corridor to the truck traffic on Highway 412 and the I-49 spur. The city has grown fast, pushing east toward the Ozark foothills and the Springdale-to-Fayetteville stretch of Razorback Greenway, with established neighborhoods around Har-Ber Meadows, Cross Church, and the older downtown grid near Emma Avenue.
The exterior cleaning conditions up here differ from Central Arkansas. NWA sits higher and cooler, and the surrounding Ozark hardwoods and pine throw heavy oak and pine pollen every spring that yellows siding and decks. Summer humidity off Beaver Lake and the White River feeds black algae and green mildew on north-facing walls, roofs, and shaded concrete. Hard well and municipal water leaves mineral spotting on glass. Red Ozark clay and gravel-road dust track onto driveways and fleet vehicles, and winter freeze-thaw works grime deep into porous concrete and brick.
We’re an Arkansas-owned company based in Conway, and Springdale sits two to three hours from our HQ. We serve the Northwest Arkansas area on scheduled routed visits and for larger, recurring, or project-based work, planned in advance rather than same-day. If you’ve got a commercial property, an HOA, a fleet, or a one-time project up here, call 501-289-5623 and we’ll find a date that routes a crew your way.

Roof Cleaning in Springdale, AR — Frequently Asked Questions
Will roof cleaning damage my shingles or void my warranty?
Not when it's done correctly. We use a low-pressure soft wash, which is the method the Asphalt Roofing Manufacturers Association (ARMA) endorses and which keeps your warranty intact. The damage comes from pressure washing, which strips the protective granules and is what voids most manufacturer warranties. We never put high pressure on a shingle roof.
What are those black streaks on my roof?
They're a blue-green algae called Gloeocapsa magma, not dirt or simple mildew. It feeds on the limestone filler in asphalt shingles and spreads by airborne spores, which is why it shows up worst on the shaded north-facing slopes that stay damp. It won't rinse off with water, it has to be killed chemically at the root, or it grows right back.
Why can't you just pressure wash it and be done faster?
Pressure blasts off the ceramic-coated granules that shield the asphalt from UV, which makes the roof fail years early, and it can force water up under the shingle courses. A soft wash kills the organism so it doesn't come back, instead of just blasting the surface stain off while leaving the colony alive and damaging the roof in the process.
How do you handle moss and lichen versus algae?
Moss and lichen are tougher because they physically root into the shingle. We treat them chemically and let them die back and release over the following weeks rather than scraping or power-washing them off, because scraping tears granules away with the growth. It looks slower, but it protects the roof and gives a lasting result instead of a quick cosmetic fix.
Do you serve Springdale?
Yes, but honestly: we're an Arkansas-owned company based in Conway, about two and a half hours southeast of Springdale, so we don't keep a crew in town. We serve the Northwest Arkansas area on scheduled routed visits and on larger, recurring, or project-based jobs that we plan ahead. We can't promise same-day or next-day service this far from our HQ, but for commercial properties, HOAs, fleets, and one-time projects, we'll route a crew up and get it done right. Call 501-289-5623 to set a date.
Why do roofs and north-facing walls get so streaky in Springdale?
Northwest Arkansas's humidity, combined with shade from the heavy Ozark tree canopy and moisture off Beaver Lake and the White River, creates ideal conditions for algae and mildew. The dark streaks on roofs are a living organism called gloeocapsa magma, and the green or black film on north-facing, shaded walls is algae and mildew that thrive where surfaces stay damp. Both need the correct soft-wash solution to actually kill the organism, otherwise it grows right back within months.
