Those dark streaks aren't dirt — they're algae, and pressure washing a roof can actually void your shingle warranty. Our network uses proper low-pressure soft-wash technique for roofs, plus full gutter cleaning and flushing so water actually drains where it's supposed to.
Get a Free Roof & Gutter QuoteSoft-wash roof cleaning, gutter cleaning and gutter guard installation — all scoped with a free assessment first.

Low-pressure, algae-killing roof treatment that removes black streaking without stripping shingle granules.

Debris removed by hand, downspouts flushed clear, and drainage checked so water actually flows away from your foundation.

Mesh or micro-mesh gutter guards installed to cut down how often cleaning is needed, especially on treed properties.
Mature tree cover across Kitchener, Waterloo and Cambridge means gutters fill with leaves, seeds and debris fast — often twice a season, not once. Clogged gutters overflow at the worst possible times (heavy spring rain, ice damming in winter) and send water pooling right next to your foundation instead of away from it.
Shaded, north-facing roof sections are also prone to the black streaking that's actually gloeocapsa magna algae, not just dirt — it spreads and can shorten shingle life if left untreated. Crews in our network use low-pressure soft-wash treatment on roofs specifically because high-pressure washing can strip granules and void manufacturer warranties.
We serve: Kitchener, Waterloo, Cambridge and surrounding the Tri-Cities communities.
No — high-pressure washing can strip protective granules off asphalt shingles and void the manufacturer's warranty. Crews in our network use low-pressure soft washing with an algae-killing solution instead, which is the industry-recommended method.
Typically $150–$300 for a standard home, depending on the number of storeys and linear feet of gutter. Heavily clogged or hard-to-access gutters may run higher.
Twice a year is typical given the tree cover in Kitchener-Waterloo-Cambridge — once in late spring after seed/blossom drop, once in late fall after leaves come down.
Yes — the treatment solution kills moss and algae at the root, not just the visible surface staining, so it stays cleaner longer than a simple rinse would.
Yes — gutter guard installation is available to cut down how often cleaning is needed, particularly useful on heavily treed properties.
