Roof Cleaning in Morrilton, AR
Hot, muggy summers feed the black gloeocapsa algae streaking common on shingle roofs across the valley, and a no-pressure chemical clean removes it without walking and cracking aging shingles.
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 Morrilton & Conway County
Morrilton is the seat of Conway County, sitting along the I-40 corridor about 35 minutes northwest of our Conway shop. It is the gateway to Petit Jean Mountain and Petit Jean State Park, with the Arkansas River bottomlands to the south and the foothills of the Ozarks climbing to the north. That mix of river-valley humidity and heavy tree cover drives most of the exterior-cleaning problems we see here.
The older neighborhoods around downtown and East Broadway hold a lot of brick and painted-wood homes built before modern drainage, so north-facing walls, porches, and roof slopes stay damp and grow black mildew and green algae fast. Pine and oak are everywhere from town out toward Petit Jean, which means real pollen loading every spring plus a steady drop of needles and tannin staining on concrete, siding, and shingles.
Summers run hot and muggy, and that humidity feeds the same gloeocapsa algae streaking you see on roofs across the river valley. Much of the area runs on well water or harder municipal supply, so glass and light-colored surfaces show spotting and mineral buildup. Spring storms blowing up the valley leave behind mud splatter, grit, and washed-down debris that settles on driveways, walks, and lower siding.
Morrilton is right in our backyard, an easy run up I-40 from our Conway shop, so it is true local turf for us. We schedule it as same-week service and can often get a crew out fast without the long-distance scheduling other companies need. You get a local team that knows Conway County conditions, not a truck driving in from out of state. Call 501-289-5623 to set up your estimate.

Roof Cleaning in Morrilton, 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 Morrilton, or is it too far from Conway?
Yes, we serve Morrilton regularly. It is only about 35 minutes up I-40 from our shop in Conway, which makes it true local turf for us. We can usually schedule same-week service and get a crew out without the long-distance routing other companies deal with.
Why does my roof and north wall get those black streaks here?
That black streaking is gloeocapsa algae, and the hot, humid air coming off the Arkansas River valley feeds it. North-facing walls and shaded roof slopes stay damp longest, so they grow it first. We use a no-pressure soft wash that kills the algae at the root rather than just rinsing the surface, which is why it stays clean far longer.
