Cornelius sits along the southern shores of Lake Norman — and that lake air brings persistent humidity that fuels algae, moss, and black streak growth on rooftops year-round. At Blast Away Pressure Washing, we specialize in professional roof soft washing in Cornelius, NC that eliminates these threats safely, without a single pound of high pressure on your shingles.
Traditional pressure washing can crack shingles, strip granules, and void your warranty. Our low-pressure soft wash system uses biodegradable cleaning solutions to kill algae, moss, mold, and lichen at the root — delivering results that last 3–5 years and keeping your warranty intact.
Pressure cleaning can strip the waterproofing granules so we use sodium hypochlorite to lift dirt.
We use low-pressure techniques to prevent damage to the protective coatings.
Our team uses a biodegradable solution that preserves the natural oils. It allows us to use less water to prevent warping.
We clean using chemicals and hardly any pressure. There’s no risk of cracking or discoloration.
The warm, humid conditions near Lake Norman make Cornelius rooftops especially prone to organic growth. If you see dark streaks running down your shingles, green or yellow patches, or crusty lichen, it’s time for a professional soft wash — before the damage spreads and shortens your roof’s lifespan.
Blast Away Pressure Washing is based in Concord, NC and serves homeowners throughout Cornelius and the Lake Norman corridor. We’re fully mobile — no travel fee, no hassle. Call or text us at 704-241-4573 or get your instant online estimate below.
