━ How We Do It

Soft Wash — The Only Safe Method

High-pressure washing blasts granules off asphalt shingles and can void manufacturer warranties. We use low-pressure soft washing with professional biodegradable solutions that kill moss, algae, and lichen at the root — without touching the shingles with damaging force.

Low-pressure application

No shingle granule loss, no manufacturer warranty issues.

Kills at the root

Moss and algae die completely, not just surface-scraped away to regrow.

Biodegradable solutions

Safe for your lawn, garden beds, and downspout drainage areas.

Heavy debris removed by hand

Thick moss is hand-cleared before treatment where needed.

Before & after photos

Full documentation provided after every job.

━ Why It Matters

What Moss & Algae Actually Do to Your Roof

Shingle Deterioration

Moss root systems physically lift and separate shingles, creating entry points for wind and water. Left untreated, it can cut 5–10 years off your roof's lifespan.

Moisture Retention

Moss holds water against your roof deck. During Edmonton's many freeze-thaw cycles each winter, this is a primary driver of premature deck rot and membrane failure.

Blocked Gutters

Algae and moss debris washes down into gutters with every rain, adding to blockage problems. A clean roof means gutters stay clear longer between cleanings.

Home Value Impact

Black algae streaks and green moss are among the first things a buyer notices. A clean roof signals a well-maintained home and can meaningfully affect sale price and buyer confidence.

━ FAQ

Roof Cleaning Questions

Will roof cleaning void my shingle warranty?

Not with our soft-wash method. High-pressure washing does void most asphalt shingle warranties — that's exactly why we don't do it. Our low-pressure application is consistent with manufacturer recommendations for roof cleaning.

How long does it take to see results?

You'll see immediate improvement after the treatment and rinse. Over the following 4–8 weeks, as rain washes dead moss and algae away, the full result becomes clear. The roof continues to improve for a couple of months.

Is the solution safe for my lawn and garden?

Yes. We use biodegradable solutions and water down any run-off areas before and after application. We've never had a plant damage complaint in our years of service.

How often does a roof need cleaning in Edmonton?

Most Edmonton homes need roof cleaning every 3–5 years depending on tree coverage and shade. North-facing slopes collect moss faster. Homes with heavy tree cover may need more frequent attention.

Satisfaction Guaranteed

If you're not satisfied with the result after the full treatment cycle completes, we'll come back and re-treat at no charge. We stand behind every job we do.
