Stop Roof Moss Before It Spreads in Vernon, BC
Let’s talk about your roof. Not the most glamourous topic, we admit — but hear us out.
If you’ve noticed green streaks, fuzzy patches, or splotches on your roof, especially on the north or shaded sides, you’re not imagining things. That’s moss — and while it might look like a whimsical forest scene, it’s actually a slow-motion home hazard.
In the Okanagan, where damp falls follow hot summers, moss thrives. And left unchecked, it can:
Lift shingles and create entry points for water
Trap moisture, leading to rot and mold
Cause clogged gutters and ice dams in winter
Shorten your roof’s lifespan (and your peace of mind)
The good news? You don’t need to grab a scraper and risk your neck. There’s a safer, smarter way: soft washing.
Why Soft Wash? Because Your Roof Deserves Better
We’ve all seen (or tried) the old-school method: pressure washing or scrubbing with a brush. But here’s the truth — high pressure can damage asphalt shingles, and aggressive scrubbing can dislodge granules, leaving your roof vulnerable.
At OKGN Soft Wash, we use a low-pressure, high-effectiveness method that eliminates moss without the risk. Our process:
Apply a biodegradable algaecide/moss killer
Let it dwell (like a good marinade for bad biology)
Gently rinse with soft wash equipment
Leave your roof clean, intact, and protected
No ladders. No damage. No moss drama.
Why Fall is the Perfect Time to Act
Moss loves cool, damp conditions — which means fall is its favourite season. But here’s the silver lining: early fall is the best time to treat it.
Why?
Moss is actively growing (easier to kill)
Dry days are still available for treatment
You prevent winter complications like ice dams and leaks
Waiting until spring means months of unchecked growth — and potentially costly repairs.
“But Isn’t Moss Natural?” (Yes — But So is Rain on Your Ceiling)
Sure, moss is natural. So is lightning. That doesn’t mean you want it on your house.
Moss holds water like a sponge. Over time, that moisture:
Seeps under shingles
Causes wood rot in sheathing
Promotes mold and mildew inside attics
And once moss takes root (literally), it’s harder to remove — and more likely to return.
How to Prevent Moss Long-Term
After your soft wash, consider these tips to keep moss at bay:
Install zinc or copper strips along the roof peak (rain washes ions down, inhibiting growth)
Trim overhanging branches to increase sunlight
Keep gutters clean to prevent water backup
Schedule a soft wash every 2–3 years (or annually in high-shade areas)
A Note on “DIY” Roof Cleaners
We get it — the home improvement aisle is full of sprays and powders promising moss-free roofs. But many contain harsh chemicals that can:
Kill nearby plants
Stain driveways
Damage metal fixtures
And without proper application, they’re often ineffective. A professional soft wash is safer, more thorough, and lasts longer.
