Roof Soft Washing in Myrtle Beach SC
Myrtle Beach roofs take a beating from humidity, salt air, and shade from live oaks and pines, which is exactly the recipe algae and lichen like. The black streaks you see on asphalt shingles are usually gloeocapsa magma, a bacteria that feeds on the limestone filler in shingles and spreads fastest in coastal, moisture-heavy climates like this one. Soft washing treats that problem without the damage a pressure washer can cause on a roof: instead of high-pressure water blasting granules loose, a soft wash applies a low-pressure mix of water with sodium hypochlorite (or a similar biocide) and surfactants to kill the algae, moss, and lichen at the root, then rinses it away gently.
When you're comparing the 58 businesses listed in this category, ask about their chemical mix and dilution ratios, whether they pre-wet and protect landscaping and gutters, how they handle different roofing materials (asphalt shingle, tile, metal), and whether they carry liability insurance in case of runoff damage to plants or siding. A crew that rushes the rinse or skips plant protection can leave you with dead shrubs or a bleached lawn.

Common questions about roof soft washing
- How much does roof soft washing cost in Myrtle Beach?
- Most homes run somewhere between $300 and $700 depending on roof size, pitch, and how heavy the algae or moss buildup is. Steep roofs, multiple stories, or tile roofing tend to push the price toward the higher end.
- How often does a roof need soft washing?
- In this climate, every 2 to 3 years is typical for asphalt shingle roofs. Homes in heavy shade or close to the marsh with more moisture exposure may need it closer to every 18 months to keep algae from taking hold again.
- Is soft washing safe for shingles?
- Yes, when done correctly it's safer than pressure washing. The low-pressure application avoids stripping granules or lifting shingle edges, which is the main damage risk with high-pressure equipment on a roof.
- How can I tell if a company did a good job?
- Look for an even, uniform color across the whole roof with no streaking, no damage to gutters or plantings below the roofline, and no lingering chemical smell after a day or two. Black streaks should be gone, not just lightened.
