The Problem

Black Streaks Are Making Your Roof Look Older Than It Is

Those dark streaks running down your roof are not dirt, and a quick rinse will not move them. They are algae, and Charleston's heat, humidity, and salt air give it everything it needs to spread across a shingle roof over a few summers. Left alone, the staining makes a well-kept house look tired and neglected from the curb. The good news is that a new roof is almost never the answer. The fix is a proper soft wash with the right cleaning solution, done at low pressure so your shingles stay protected, and priced as one flat rate so you know the cost before we ever climb a ladder.

"A roof full of black streaks does not need replacing. It needs a low-pressure soft wash and a price you can see up front."

The Pressure Wash Charleston Solution

How We Get Your Home Truly Clean

  • Low-pressure soft wash kills the algae at the root, so the black streaks stay gone for years, not weeks.
  • One flat rate, quoted before we start, with no upcharges once the crew is on site.
  • No high pressure on your shingles, which keeps the protective granules in place.
  • We pre-wet and rinse your plants, beds, and grass as part of the job.
  • Before-and-after photos with every clean, so you can see exactly what came off.
  • Ground- and ladder-based work, fully backed by $2M in insurance.

Why Pressure Wash Charleston

Roof Cleaning Done Right, The First Time

Commercial-grade roof cleaning, priced up front

We clean residential asphalt shingle roofs with the same low-pressure soft wash we use on commercial buildings, scaled down for your house and quoted as one flat rate. No surprise upcharges once we are on site, and no pressure on your shingles. The cleaning solution does the work, lifts the black staining, and leaves the roof looking like the rest of the house finally caught up to it.

You get the quote before we start, a crew that protects your plants and gutters, and before-and-after photos so you can see exactly what came off. Our work is backed by $2 million in insurance, so the only thing leaving your roof that day is the algae.

Soft wash, not power wash

A roof should never be blasted with high pressure. That strips the granules that protect your shingles and can cut years off the roof's life. Soft washing applies the cleaning solution at low pressure, kills the growth at the root, and rinses clean. It is the right method for asphalt shingles, and it is the only method we use on a roof.

Kiawah Island

Years of algae had darkened whole planes of this slate roof, heaviest where the shade sits longest. Soft washing lifts the growth chemically, because slate of this age and value will not take pressure.

Questions

Common Roof Cleaning Questions in Charleston, SC

Straight answers to the questions Charleston businesses and property managers ask most.

Will the black streaks come back?

Soft washing kills the algae at the root, not just the surface, so the streaks do not grow back the way they would after a quick rinse. In Charleston's heat and humidity, regrowth is slow, and most homeowners go a few years between cleanings. Shaded slopes under trees grow algae faster, so we will tell you what to expect for your specific roof.

Does soft washing damage my shingles or void the warranty?

No. Soft washing uses low pressure, around garden-hose strength, so the protective granules on your shingles stay put. High-pressure washing is what damages a roof and risks the warranty. We never put high pressure on a residential roof.

Is the flat-rate price really the final price?

Yes. We look at your roof, give you one flat rate up front, and that is what you pay. There are no hidden fees added once the crew arrives. If anything about the job is unusual, you will know before we start, not after.

Will the cleaning solution hurt my plants or landscaping?

We pre-wet the shrubs, flower beds, and grass around your home before we start and rinse everything down again when we finish. Taking care of the landscaping is part of the job, not an extra.
