    Common questions

    Roof Cleaning — answered

    How do I know if my roof actually needs cleaning?

    Visible moss, lichen, dark streaks running down shingles, or organic debris build-up in valleys are the obvious signs. Quebec’s climate (lake-effect winter precipitation and significant freeze-thaw cycling) compounds this — north-facing slopes under maple, oak, and mature urban deciduous canopy canopy show growth first. A roof inspection during a gutter visit catches it early.

    Will pressure washing damage my shingles?

    Yes — high-PSI water on asphalt shingles strips the granular surface that protects the asphalt below, dramatically shortening roof lifespan. Roof cleaning is exclusively soft-wash with biodegradable solutions that kill organic growth at the root, with rinse water gravity-running off naturally.

    What's the eco-friendly solution actually doing?

    It’s a low-concentration sodium hypochlorite or biodegradable surfactant blend that kills moss, lichen, and algae spores in the substrate without damaging shingles. Crews pre-rinse surrounding landscaping and post-rinse runoff areas — the solution dilutes to safe levels in rinse water and breaks down within days.

    Do zinc strips really prevent regrowth?

    Yes — strips installed at the ridge release small amounts of zinc that wash down with rain and inhibit moss and algae regrowth. Worth installing right after a fresh clean for maximum benefit. Adds 10–15% to the project cost but extends the time before re-treatment is needed.

    How long until I see the full result?

    Heavy moss visible day-of will be loosened and largely gone within 24 hours. Lichen and dark algae streaking continue to fade over 2–4 weeks as the killed organisms wash off with rain. Don’t judge the result on cleaning day — the roof keeps improving for a month afterward.

    When is the best time of year to schedule?

    Late spring through early fall is ideal — solution dwells properly and rinses fully when temperatures stay above 10°C and rain isn’t actively falling. May, June, and September are peak booking months. Avoid mid-summer extreme heat when chemistry doesn’t work optimally.

    Should I bundle with gutter cleaning?

    Strongly recommended — roof debris loosened during cleaning ends up in the gutters, so gutter clearing the same day captures everything and saves a second visit. Most franchises offer a bundle discount for same-day roof + gutter service.

    How is the service priced?

    Quebec roof cleaning pricing scales with square footage, pitch (steeper = more setup), growth severity, and substrate type. Asphalt shingle on a single-storey detached home falls in a clear range; multi-storey, complex roof geometry, or specialty materials cost more. Quote provided after on-site walkthrough.

    Are crews insured and trained for height work?

    Yes — liability and WCB certificates available on request. Roof work is high-risk by definition; crews are trained in fall-arrest, ladder safety, and the specific chemistry/PSI calibrations that protect the substrate. Anyone working on your roof should be able to produce certificates same-day.
