That moss isn’t just an eyesore
Moss acts like a sponge. It holds water against your shingles long after the rain stops, and as it grows it can lift shingle edges and get in the way of proper drainage. Left alone, small patches become thick mats, and a maintenance job slowly turns into a repair.
Kelowna is dry compared with the coast, but moss still does well on the shady side of a roof: north-facing slopes, roofs under pines and firs, and anywhere needles collect and stay damp through fall rain and spring melt.
- Protect your shingles so the edges that keep wind and water out stay flat.
- Get ahead of moisture before it becomes a bigger, costlier problem.
- Get your curb appeal back and stop worrying about the roof every time you pull into the driveway.
Never scraped. Never pressure washed.
It’s tempting to climb up with a scraper or a pressure washer. Both can strip the protective granules off asphalt shingles and damage the shingles themselves. We use the gentle method shingle manufacturers recommend instead.
Aggressive removal
- Pressure washing strips protective granules from shingles
- Scraping and wire brushes can gouge or loosen shingles
- A wet, mossy roof is a real fall risk for homeowners
The Next Level way
- Big clumps gently broomed down, never scraped
- Low-pressure liquid treatment that kills moss to the root
- Dead moss loosens and weathers away on its own, without force
What happens on your roof
Every visit follows the same careful process, so you know exactly what to expect.
Broom down the big clumps
We clear the heavy moss and loose debris by hand, working down the slope so nothing is pushed under the shingles.
Clean up the gutters and the mess
Moss and debris that land in your gutters are cleared out, and we clean up below so your property is left as tidy as we found it.
Apply the treatment
Our liquid treatment goes on at low pressure and kills the moss and its roots. You’ll often see it turn lighter within minutes.
Final check
We check the work area, finish the cleanup and let you know when we’re done, along with what to expect over the coming months.
The moss dies first. Your roof keeps getting better.
A treated roof won’t look perfectly clean the same afternoon, and that’s by design. The treatment kills the moss, then the dead moss shrinks and weathers away with the wind and rain.
- Treatment dayThe moss starts turning lighter or whitish.
- 4 to 12 weeksYour roof looks noticeably better as the dead moss breaks down.
- Following monthsWeather carries the remaining dead moss away.
- 6 to 9 monthsYour roof is typically looking like new.
Timing is an estimate, not a guarantee. It depends on weather, shade, roof pitch and how much moss there was to begin with.
Choose the treatment that fits your roof
Most homeowners choose the Complete Roof Treatment for the peace of mind of the warranty. If the moss is limited to a few spots, a Targeted Treatment may be all you need.

warranty
Five years of protection. Transferable if you sell.
Every Complete Roof Treatment comes with our limited five-year warranty:
- Free retreatment of qualifying fresh green moss for the first 24 months.
- Retreatment at 50% of the applicable cost in years 3 to 5.
- The warranty transfers to the new owner if you sell your home.
The warranty covers our treatment, not the roof itself. Keeping the roof clear of debris and trees trimmed back helps it stay clear longer.

The crew showed up on time and was very friendly. They did a great job on the gutter cleaning and moss treatment and notified me when they were done. Highly recommend
Hired to treat moss on the roof. Setting up an appt was easy, they arrived promptly, did a good job and there was follow up done, which I appreciated.
We were recommended Next Level to do our moss removal and they delivered! I was especially impressed with their customer service. They had quick, clear communication and were very respectful and pleasant. Would highly recommend!

Roof moss questions homeowners ask us
How much does roof moss treatment cost in Kelowna?
Most Kelowna homes pay $415 to $1,125 before GST. A Targeted Treatment of the affected areas starts at $415, and a Complete Roof Treatment of the whole roof, with the five-year warranty, starts at $475. Your price depends on the size and pitch of your roof, access and how much moss has built up. See our price guide or request a free quote for your exact price.
Will the moss disappear right after treatment?
Not all of it. The treatment kills the moss, which often turns lighter or whitish right away. The dead moss then shrinks and weathers off. Most roofs look noticeably better within 4 to 12 weeks and are typically looking like new in 6 to 9 months, depending on weather, shade and how much moss there was.
Will your treatment damage my shingles?
No. We never pressure wash and never scrape. We gently broom down the big clumps, then apply a low-pressure liquid treatment. It’s the gentle method shingle manufacturers recommend.
Why shouldn’t I just pressure wash or scrape the moss off myself?
Pressure washing strips the protective granules from asphalt shingles, and scraping or wire brushing can gouge or loosen them. A wet, mossy roof is also a dangerous place to work. Treating the moss and letting it weather away protects both your roof and you.
What’s the difference between a Complete Roof Treatment and a Targeted Treatment?
A Complete Roof Treatment covers the whole roof and includes our limited five-year transferable warranty. A Targeted Treatment covers only the areas with visible moss and has no warranty. Both include brooming down the big clumps, clearing moss and debris from the gutters and cleaning up.
What does the five-year warranty cover?
For the first 24 months we retreat qualifying fresh green moss for free. In years 3 to 5, retreatment is 50% of the applicable cost. If you sell your home, the warranty transfers to the new owner. It covers our treatment, not the roof itself.
Do I need to be home?
No. Most roofs can be measured by satellite and priced over the phone, and we can do the work while you’re out. We’ll let you know when we’re on the way and when we’re done.
When is the best time to treat roof moss?
Moss grows most in cool, damp weather, so fall and spring are popular times to treat. A fall treatment gets ahead of another wet season, and the weather that follows helps the dead moss weather away.
Do you treat metal, cedar or tile roofs?
Asphalt shingle roofs are our standard. Tile roofs are priced higher, and metal and cedar shake roofs get a site visit first so we can recommend the right approach.
Should I get my gutters cleaned at the same time?
It’s a smart pairing. Moss treatment includes clearing the moss and debris that land in your gutters, and a full gutter cleaning on the same visit clears every gutter and checks the downspouts while our crew is already set up at your home.
