Roof Cleaning in Texarkana, AR
Those dark streaks running down north-facing shingles are Gleocapsa magma algae fed by year-round humidity, and they require a no-pressure roof treatment, never a power washer 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.
Our Work in Texarkana, AR
Texarkana is a Miller County community and our crews run it out of our Conway yard — 164 mi of driving, about 2 hours 28 mins.
We work across Texarkana regularly, including properties around Ferguson Park, Texarkana Parks & Recreation and Jefferson Park Outdoor Amphitheater.

Camden is 70 miles on from Texarkana, so the two are usually scheduled in the same run.
The typical Texarkana property was built around 1978. There are roughly 13,738 housing units in the city. Most of the housing stock here predates 1980, which usually means original wood or masonite siding, older roof systems, and decades of weathering that a newer subdivision simply has not accumulated yet.
Roof Cleaning in Texarkana & Miller County
Texarkana sits in the far southwest corner of Arkansas, the seat of Miller County, straddling the Texas state line where I-30 meets US 59/71. The Arkansas side runs east of State Line Avenue through neighborhoods like Highland Park, College Hill, and out toward the newer subdivisions off Richmond Road and around Pleasant Grove. It is closer to Dallas than to Little Rock, which is exactly why so much of the region gets ignored by Central Arkansas contractors.
The conditions here are tough on exteriors. This is the heart of pine country on the edge of the Piney Woods and the Sulphur River bottoms, so loblolly pollen coats everything yellow in spring and pine sap, needles, and tannin staining are constant on roofs, gutters, and concrete. Summers are humid and long, which feeds black algae (Gleocapsa magma) streaking on north-facing roof slopes and green mildew on shaded siding and fences. Proximity to Wright Patman Lake and the river bottoms keeps moisture and mildew pressure high year-round. Hard, mineral-heavy water leaves white scale on windows and brick. Red iron-rich clay tracks onto driveways and walkways, and pollen-fed organic growth makes north-side surfaces the first to go green.

Roof Cleaning in Texarkana, 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. Our Texarkana routes already take in the areas around Ferguson Park, Texarkana Parks & Recreation, Jefferson Park Outdoor Amphitheater.
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. We cover Miller County generally, not only the Texarkana city limits.
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. For Texarkana specifically, we are 164 mi away — about 2 hours 28 mins — so early starts and off-hours work are practical here rather than theoretical.
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. Texarkana runs on the same schedule as Hope (30 mi), Apartment Washing (31 mi), Magnolia (47 mi), so a nearby booking often means we can reach you sooner.
Do you really service Texarkana if you are based in Conway?
Yes, but honestly. Texarkana is about two and a half hours from our Conway headquarters, so we serve it on scheduled, routed visits rather than same-day calls. We are the right fit for larger one-time projects and for recurring or commercial accounts we can plan around. Call 501-289-5623 and we will get you on an upcoming route to Miller County. The typical Texarkana property dates to around 1978, which mostly means older exteriors with original siding and aged roof systems.
Why do roofs in Texarkana streak black so quickly?
It is the climate. Texarkana sits in humid pine country near Wright Patman Lake and the Sulphur River bottoms, and that constant moisture feeds Gleocapsa magma algae that streaks dark down north-facing shingles. It is organic, not dirt, so it needs a low-pressure roof treatment that kills the algae rather than a power washer that would strip your shingle granules and shorten the roof's life. There are roughly 13,738 housing units in Texarkana, and we route the whole city rather than one subdivision.
