A Gentle Wash That Makes Roofs Look Years Newer
Algae grows on damp asphalt shingles, and a soft wash stops it at the root. Pressure is the wrong tool, because it blasts off the granules that shield shingles from the sun. Most roofs look years newer the same day, and leftover shadows fade after the next rain.
This service is part of our roof cleaning work and our broader pressure cleaning services in Wilmington.
This service fits homeowners with a streaked roof, sellers getting ready to list, and landlords who want a tidy property. A curb photo and a quick call are enough to start.
What Goes Into a Shingle Roof Visit
Each visit covers the whole roof, not just the streaks you can see from the driveway.
- Every slopeNorth facing and shaded planes first.
- Ridge and valleysWhere water collects and growth hides.
- Flashing areasAround vents, chimneys and skylights, with extra care.
- Gutter run offFlushed so it does not stain siding or the driveway below.
- Plants and bedsWet down before and after.
Why Shingles Streak So Quickly Here
Fog and humidity keep north slopes damp in Wilmington. The air carries about 74 percent humidity on average, and the area sees roughly 122 rainy days a year. Shaded planes under oaks and pines hardly ever dry out.
Streaks show on those slopes first and climb from there. Buyers and inspectors often mistake them for a worn out roof, and the cost shows up at pre listing time. A cleaned roof tells a more honest story about the shingles underneath.
How the Wash Works, Start to Finish
The plan is short, and the dwell time does the real cleaning.
- Check the shinglesWe look for curling edges, bare spots and loose tabs before water goes on.
- Wet the plantsBeds and shrubs under the eaves get a soak.
- Apply the mixA bleach and water style mix goes on at low pressure.
- Wait 15 to 20 minutesThe mix kills the algae while it sits.
- Rinse gentlyA soft rinse clears the roof, then the plants get rinsed again.
- Take photosSame street spot as the first photo.
Some streaks keep fading for a week or two as rain rinses away the dead algae. That is normal. Our method follows the same soft washing idea we use on siding, adjusted for the roof.
What We Remove From Shingles
Here is the list, and where the limits sit.
- Black streaksAlgae, and the most common call we get.
- Green algaeOften on the shaded side near trees.
- Light mossLoosened by the mix and carried off with the rinse.
- LichenGripping and slow, and it may need a second pass.
If we see curling, cracked or missing shingles, we tell you and take photos. A roofer should handle repairs, and we would rather say so than clean over a problem.

Roof size, pitch, height and how thick the growth is move the price. These ranges are a starting point until we see photos.

| Average two story roof | $450 to $650 |

A bigger house, a tall roofline and heavy moss mean more time. We give a range before the visit and confirm it on site.

Why Gloeocapsa Magma Removal Matters
The science term sounds fancy, but the point is simple. That is what a soft wash does, and it works because the mix reaches the living cells. Scrubbing and blasting only smear the dark sheath around it.
Roof algae removal Wilmington owners ask about is the same job. Once the algae dies, the sheath rinses away with rain, and the shingles go back to their original gray or brown.
Questions About Shingles and Pressure
Does pressure washing damage shingles?
Yes. High pressure blasts off the granules that protect asphalt shingles from the sun, which can shorten the life of the roof. The Asphalt Roofing Manufacturers Association (ARMA) warns against it, and a soft wash cleans without that damage.
Will roof cleaning void my warranty?
A soft wash with a bleach and water type mix follows the approach ARMA describes, which is what most makers expect. Pressure washing is the thing to avoid. Read your own warranty terms to be sure, since they vary by brand.
Why are the streaks still a little dark after cleaning?
Dead algae can leave a faint shadow that fades over a week or two as rain rinses it away. If it does not fade, call us and we will take a look.
Other Roof Types and Reasons People Call
Not every roof is shingle. Metal roofs, tile and flat porch roofs need their own approach, and we handle each one with a gentle method.
Some owners call only to prepare for a sale. Roof cleaning before home inspection is a smart move, because streaks get mistaken for age. A bright roof also photographs better for listing day.
