Gentle, shingle-safe roof cleaning that lifts black streaks and buys your roof years.
Those dark streaks running down your roof aren't dirt — they're algae feeding on the limestone filler in your shingles. Left alone, the algae spreads, holds moisture against the shingle, and shortens the life of the entire roof. A roof replacement is one of the most expensive things a home will ever need.
We clean roofs the way the shingle manufacturers recommend: soft washing, never high pressure. High pressure strips the protective granules and voids warranties. Our low-pressure soft wash lifts the black streaks, moss, and lichen, kills the algae at the root, and extends the life of the roof you already paid for.
Gloeocapsa magma algae eating the limestone in your shingles. It spreads every season it's left alone — and it never goes away on its own.
Moss holds moisture directly against the shingle and pries at the edges as it grows. We kill it at the root and let it release — no scraping.
Lichen bonds to the shingle surface and takes granules with it if it's torn off. A proper soft-wash treatment kills it so it lets go on its own.
Algae and moss shorten shingle life. Cleaning from $400 versus replacing a roof years early is the easiest math in home maintenance.
Anyone offering to pressure wash your shingles is offering to damage them. Manufacturers specify soft washing — it's the only method we use up there.
A streaked roof reads as 'old roof' to every buyer who pulls up. A soft wash resets that impression for a fraction of a repair credit.
Low-pressure soft washing only — the method shingle manufacturers actually recommend. Your granules and warranty stay intact.
Runoff is managed and plants are pre-wet and rinsed. What comes off your roof does not end up killing your shrubs.
While we're up there we note loose shingles or trouble spots and tell you straight — we clean roofs, we don't sell them.

Roof washing is dry-weather work, so spring through fall is the main season — and the solution needs time on the shingle, so we schedule around rain. If your roof is streaked now, book ahead: dry weekends go first, and the growth compounds every season it waits. Get your instant quote →

That is algae — Gloeocapsa magma — feeding on the limestone filler in your shingles. It spreads over time, holds moisture against the roof, and shortens shingle life. Soft washing kills it at the root and lifts the staining.
Yes. Algae, moss, and lichen hold moisture and degrade shingles from the surface down. Removing them and killing the root slows that decay — a clean from $400 is a fraction of the cost of replacing a roof years early.
Most roofs benefit from a soft wash every two to three years, sooner if you live under heavy shade or see streaks returning. Catching it early keeps the growth from getting established.
Yes. Moss and lichen take root in the shingle and need a proper soft-wash treatment to kill and lift without prying at the shingles. We treat them at the root so they do not simply grow back.
