    Wilmington roof soft washing

    What those black streaks really are, and why they spread

    Roof soft washing is the low pressure cleaning of your roof to kill and remove the algae, moss and lichen growing on it. The black streaks you see running down a Wilmington roof are Gloeocapsa magma, a blue green algae that feeds on the limestone filler in asphalt shingles. It is alive, it is spreading, and it holds moisture against your shingles that shortens their life.

    This is why a roof cannot be pressure washed. Unlike pressure washing in Wilmington on concrete and driveways, high pressure on a roof strips the protective granules off your shingles and takes years off the roof, while leaving live spores behind to grow straight back. Soft washing uses a cleaning solution at low pressure that kills the organism at the root, which is exactly what the Asphalt Roofing Manufacturers Association recommends.

    In Wilmington the problem is worse than inland. Salt air and high coastal humidity keep the roof damp, and shade from the live oak canopy stops it drying out. A shaded north slope under trees in Landfall or Autumn Hall can go from clean to heavily streaked in two or three seasons.

    What we treat on a Wilmington roof

    Asphalt and architectural shingles the most common roof here, soft washed at low pressure to protect the granules
    Black algae streaks Gloeocapsa magma killed at the root so it does not just grow back
    Moss and lichen the raised green growth that grips the shingle, common under heavy canopy
    Metal and low slope roofs cleaned with the right solution strength for that material
    Roof valleys and north slopes the shaded spots that always grow first and worst
    Gutter areas and roof edge where runoff carries the growth down onto your siding

    If you have searched for roof cleaning, shingle cleaning or black streak removal in Wilmington, this is what you need: soft washing Wilmington roofs the right way kills the algae, where a pressure wash only damages the shingles.

    How we do it safely

    How roof soft washing actually works, step by step

    People worry about anyone walking on their roof or spraying chemicals near it. Here is exactly how we do it, safely, with nothing hidden.

    1

    We protect the roof and everything below

    Plants, shrubs and grass around the house are soaked with water first and rinsed after. We work off ladders and from the edge wherever possible so we are not grinding granules underfoot.

    2

    A soft wash solution is applied at low pressure

    A cleaning solution goes on at low pressure and breaks down the algae, moss and lichen at the root. It is the chemistry that does the work, never force, so your shingles and granules are never touched by high pressure.

    3

    The solution dwells and kills the colony

    It sits long enough to kill the organism completely. Lichen and heavy growth get a longer dwell, and a second pass where needed, so it does not simply grow back in a few months.

    4

    A gentle low pressure rinse

    Once the growth is dead we rinse gently. The streaks lift, the roof looks clean, and because the colony is dead at the root the result holds for years, not weeks.

    The result is a roof that looks new again and shingles that last their full rated life, because the algae is dead and the granules are intact. That is the difference between soft washing and a pressure wash that strips years off your roof.

    Why Wilmington chooses us

    Why homeowners here trust us on their roof

    Soft wash, never high pressure

    Your roof never sees a pressure wand from us. We soft wash the way the Asphalt Roofing Manufacturers Association recommends, so the algae dies and your granules stay put.

    We will not void your warranty

    Most shingle warranties are voided by pressure washing. Our low pressure method is the one manufacturers specify, so your coverage stays intact.

    Plant safe, every single time

    We soak and protect your landscaping before we start. The runoff from a roof wash is exactly what kills plants when a crew skips this step.

    Flat price, no surprises

    A flat number before we start and the invoice matches it. No starting at pricing, no hourly billing, no number that grows on invoice day.

    We know Wilmington roofs

    Landfall canopy, Porters Neck lichen, Wrightsville salt. We know which roofs grow what, because we work these neighborhoods every week.

    Before and after photos

    Every job documented. You see the difference, and if your HOA cited your roof, you get a written record you can submit straight to the board.

    What we remove

    The growth we clear off Wilmington roofs

    Most roofs we clean here have more than one thing growing at once. Each one needs the right dwell time and solution strength to kill cleanly without harming the shingles underneath.

    Common roof growth we clear in one visit

    Black algae streaks Gloeocapsa magma, the dark streaks that feed on shingle filler and hold moisture
    Moss the thick green cushions in shaded valleys that trap water against the roof
    Lichen the raised crusty growth that grips the shingle, common in Porters Neck and under canopy
    Roof mildew and mold the darker patches on the most shaded, least dried slopes
    Salt and organic film the haze near the water that keeps the surface damp and feeds new growth
    Debris and leaf staining tannin and organic buildup from the live oak canopy overhead

    Soft washing kills and clears all of it in one visit without touching the granules, which is why it is the only method that makes sense for a roof.

    Common questions

    Roof soft washing questions Wilmington homeowners ask

    How much does roof soft washing cost in Wilmington NC?
    Most roofs run $350 to $650, with larger or steeper roofs quoted on site. The price depends on roof size, pitch, how heavy the growth is and access. You get a flat price before we start, with plant protection and photos included. It is a fraction of what premature shingle replacement costs.
    Will soft washing damage my shingles or void my warranty?
    No, the opposite. High pressure washing strips granules and voids most shingle warranties. Soft washing at low pressure is the method the Asphalt Roofing Manufacturers Association recommends, so it protects both your shingles and your warranty.
    What are the black streaks on my roof?
    Gloeocapsa magma, a blue green algae that feeds on the limestone filler in asphalt shingles. It is a living organism, not a stain, which is why bleach from a hose or a rain shower does not remove it. It holds moisture against the roof and shortens its life, so clearing it protects the shingles.
    How long does a roof soft wash last in Wilmington?
    Two to three years for most roofs here, shorter under heavy canopy where shade keeps the surface damp, longer on open sunny roofs. Because we kill the algae at the root rather than just rinsing the surface, it does not grow straight back the way a pressure wash lets it.
    Is it safe to soft wash a roof, or will someone damage it walking on it?
    It is safe. We work off ladders and from the roof edge wherever possible, so we are not walking the shingles and grinding granules. The cleaning is done by the solution, not by scrubbing or pressure, which is exactly what keeps the roof intact.
