Roof Cleaning in Paragould, AR
Those dark streaks running down shingles are Gloeocapsa magma algae feeding on the long humid season, and a no-pressure roof treatment kills it at the root instead of just rinsing the surface.
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 Paragould & Greene County
Paragould is the seat of Greene County, sitting up in the northeast corner of Arkansas where Crowley’s Ridge tapers off into the flat Delta farmland of the Mississippi Alluvial Plain. The town itself runs along the ridge, so you get a mix of old hilly neighborhoods near Downtown and the courthouse square and newer subdivisions spreading out toward the flats. Areas like Lakewood, the homes around Greene County Tech, and the stretches along Linwood Drive and Highway 49 see the usual range of brick ranches, vinyl siding, and metal-roofed shops.
The local conditions are what matter for exterior cleaning here. Crowley’s Ridge is heavily wooded with oak, hickory, and loblolly pine, so spring pollen is brutal and pine sap and needle litter coat north-facing roofs and gutters. Delta humidity stays high through the long growing season, which feeds black algae (Gloeocapsa magma) streaking on shingles and green mildew on north and shaded siding. Agricultural dust off the surrounding rice and soybean fields settles on everything, and a lot of properties run on well water with high iron and mineral content, leaving orange staining on concrete, brick, and anywhere a sprinkler or hose bib runs.

Roof Cleaning in Paragould, 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 Paragould, or are you too far away in Conway?
We do serve Paragould, but let's be straight about how. We're an Arkansas-owned company headquartered in Conway, about two to two-and-a-half hours southwest, so we don't keep a crew sitting in town. We reach Paragould through scheduled, routed visits and are a strong fit for larger one-time jobs, recurring service, and multi-property or commercial accounts. We won't promise same-day work at this distance, but we'll give you an honest date when we route up that way. Call 501-289-5623.
Why does my Paragould roof have dark streaks even though it isn't that old?
Those streaks are almost always Gloeocapsa magma, a roof algae that feeds on the long, humid growing season here on Crowley's Ridge, and it's made worse by the shade and pine litter from the wooded areas around town. It isn't dirt you can rinse off; it's a living organism rooted in the shingle granules. A proper low-pressure roof treatment with the right solution kills it so it doesn't come right back, rather than blasting the surface and damaging the shingles.
