Roof Cleaning in Rogers, AR
Black gloeocapsa streaking is common on north-slope asphalt shingles here, and a low-pressure roof treatment kills the staining algae instead of blasting granules off the shingle.
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 Rogers & Benton County
Rogers sits in Benton County at the north end of Northwest Arkansas, sharing a seamless border with Bentonville and Lowell along the I-49 corridor. It is a fast-growing city, and that growth shows in the mix of property here: established older homes near downtown and Lake Atalanta, dense newer subdivisions out east toward Beaver Lake, and the upscale commercial and residential build-out around Pinnacle Hills, the Promenade, and the Pleasant Crossing area.
The local conditions are real and they matter for exterior surfaces. NWA gets meaningful humidity through the summer and a hard spring oak and pine pollen season, which feeds green algae and black gloeocapsa staining on north-facing roofs and shaded siding. Tree cover is heavy in the older neighborhoods, so leaf and seed litter clogs gutters fast. Properties near Beaver Lake and along the creeks see extra mildew and that gray-green film on decks, docks, and concrete from the constant moisture. Much of the area runs on harder water as well, which leaves mineral spotting on windows and glass. Winters bring real freeze-thaw cycling, so driveways and walkways pick up the gritty, slick organic buildup that needs cleaning before it turns into a slip hazard.
Rogers sits about 2 to 3 hours northwest of our Conway headquarters, at the far end of our service map. We are an Arkansas-owned company and we cover the Rogers area on scheduled routed visits, and we are especially well suited to larger, recurring, or project-based work where planning ahead makes sense. We do not run a same-day crew in town up here, so the right approach is to book in advance. Call 501-289-5623 and we will set a date that works.

Roof Cleaning in Rogers, 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 actually serve Rogers, or are you too far away in Conway?
We do serve Rogers. It is about 2 to 3 hours northwest of our Conway headquarters, so we are honest that we are not a same-day, in-town crew up here. We are an Arkansas-owned company that covers the Rogers area on scheduled routed visits, and we work especially well for larger, recurring, or project jobs that are planned in advance. Call 501-289-5623 to set a date.
Why does my Rogers roof have those dark streaks on one side?
Those streaks are gloeocapsa algae, and in Northwest Arkansas they show up worst on the shaded, north-facing slope where pollen and humidity keep the surface damp. It is staining, not shingle wear, and a low-pressure roof treatment kills the algae without stripping the granules. It will return over time in this climate, so periodic cleaning keeps it in check.
