“black streaks on our roof that Blair immediately identified and removed”
No-pressure method
A low-pressure treatment kills algae and moss at the root — shingles are never blasted or scraped.
Stops the streaks
Removes the black gloeocapsa streaks that make a good roof look old.
Warranty-safe
The soft-wash approach roofing manufacturers actually recommend.
What to expect
A soft wash — and a roof that keeps improving for weeks.
Those black streaks aren’t dirt — they’re gloeocapsa algae, feeding on the limestone filler in your shingles. A pressure washer strips the protective granules off along with the algae, shortening the roof’s life and voiding most shingle warranties. So we do the opposite: a low-pressure soft wash that kills the algae and moss at the root.
Worth knowing up front: the streaks clear fast, but heavy moss doesn’t vanish the day we leave. Killed at the root, it dries out and sheds on its own over the following weeks with wind and rain. Slower than scraping it off — and exactly what keeps your shingles whole.
The payoff: a roof that looks its age instead of a decade older, keeps its warranty intact, and gets the full life you paid for. From the street, it’s often the biggest single lift to a home’s curb appeal.

“Our home in Severn needed a house wash to get rid of the grime and mildew, and we also had a little moss growing on some of our shingles. Blair and Tyler showed up promptly to take care of the job, and everything looks great again.”
“Blair did an absolutely stellar job cleaning the exterior of my home - literally from top to bottom: gutters, siding, flat roof, windows & deck. It was super easy and quick to get a detailed quote with a breakdown of every service offered.”
Before & after

Not renders, not stock photos — actual Simcoe County homes. Roofs are the one service where the “after” takes time: the treatment kills the moss at the root and the dead growth sheds over the following weeks.

Good to know
Common questions about roof cleaning
Will roof cleaning damage my shingles or void the warranty?
No. We never pressure-wash a roof — that’s what tears granules off shingles and shortens their life. We use a low-pressure soft-wash treatment, which is the method asphalt-shingle manufacturers actually recommend, so your roof and its warranty stay intact.
Why is there still moss on my roof right after the cleaning?
Because scraping live, rooted moss off shingles damages them. Our treatment kills the moss at the root; the dead material then dries out and sheds naturally over the following weeks and months with wind and rain. It’s slower than ripping it off, but it’s what keeps the shingles whole.
What are the black streaks on my roof?
That’s gloeocapsa algae — the dark stains that make a sound roof look old and tired. The soft-wash treatment clears it and stops it from feeding on the shingles, so the roof looks its age again instead of older.
How much does roof cleaning cost?
We quote roofs from satellite imagery, so you get a firm number without waiting for a site visit. Every roof is different — pitch, size, and how much growth is up there — so the instant number is based on your actual roof, not a guess.
How often does a roof need cleaning?
Only when the streaking or moss comes back, which depends on shade and moisture. Roofs under trees or on the damp, north-facing side grow algae fastest; a sun-baked roof can go years. We’ll give you an honest read on your timeline when we’re there.
