Roof Washing

Why Is Roof Cleaning Important?

Wondering what those dark streaks on your roof really are?

Those black stains are mold, algae, and lichen — and they’re slowly eating away at your shingles. Modern roofing materials contain limestone, which becomes the perfect food source for algae. Left untreated, this growth can shorten the lifespan of your roof, increase energy costs, and dramatically reduce curb appeal.

These stains usually appear first on the north-facing or shaded sides of the roof where the sun can’t evaporate moisture quickly. This creates the damp environment algae and mold love to grow in.

At Pressure Doctor, our certified soft wash roof technicians safely eliminate all mold, algae, moss, and organic buildup without using high pressure. High pressure can damage shingles — we never use it. Our commercial-grade detergents and ARMA-approved cleaning methods restore your roof’s appearance and protect your investment long-term.
