Late fall is when a lot of East Kootenay homeowners climb a ladder to clear gutters and take a look at the shingles. If the roof looks dry and tired, a hardware-store roof spray can seem like a cheap weekend fix. Here's the honest trade-off between doing it yourself and having it done professionally, and which jobs really are fine to handle on your own.
What a DIY Roof Treatment Gets You
Consumer roof sprays exist, and they vary a lot. Most are short-term products. The upside is real: the product costs less up front and you work on your own schedule. The question that matters is whether the roof ends up properly restored, with protection you can count on years from now.
What You Give Up
- The warranty. This is the big one. A spray you apply yourself comes with no professional, transferable warranty, so there's nothing to hand to the next owner if you sell.
- Safety. Ladders, height and slick shingles make roof work risky, and falls are a leading cause of serious home-maintenance injuries. In Cranbrook, Kimberley or Fernie in late fall, add morning frost and the first skiff of snow.
- A candidacy check. Without an assessment you may treat a roof that's too far gone, or miss damage that needs repair first. See our five-step candidacy check for what we look at.
- Even coverage. DIY jobs often leave thin spots and missed areas, and there's no easy way to confirm the product worked.
- A tested system. A consumer product isn't a professionally formulated, independently tested treatment.
What a Certified Contractor Brings
When we treat a roof, it starts with a free assessment to confirm the roof is aging but sound and to match the right NuRoof system. Application is done by trained installers with full, even coverage. The treatment is independently tested to UL 2218 Class 4 for impact, ASTM D3161 Class F for wind (110 mph, about 177 km/h) and UL 790 Class A for fire; more on that in how a treated roof stands up to hail, wind and fire. And it comes with a written, transferable warranty of up to 20 years.
On cost, a roof rejuvenation from Key City runs $2,500 to $6,000 for an average home, about 80% less than the $20,000 or more for a new roof, and financing starts at $149 a month.
Roof Jobs That Are Fine to Do Yourself
Plenty of roof care belongs to the homeowner, as long as it happens from the ground:
- Keep gutters and downspouts clear, especially before the first hard freeze.
- Clear leaves, needles and branches you can reach safely.
- Watch for granules in the gutters, moss and curling shingles.
- Book a professional inspection when something changes.
Leave the restoration treatment and any on-roof work to a professional. Our fall roof prep guide covers the rest of the seasonal checklist.

Frequently Asked Questions
Can I treat my own roof?
You can buy a consumer roof spray and apply it yourself, but you get no professional warranty, no assessment of whether the roof qualifies, uneven coverage, and real fall risk.
Does a DIY roof treatment come with a warranty?
No. A product you apply yourself does not come with a professional, transferable warranty that can pass to the next owner.
Why isn't Gonano's roof treatment sold for DIY?
By design. The warranty, the candidacy assessment, proper application and the tested performance all depend on installation by a certified contractor.
What roof maintenance can I safely do myself?
Ground-level jobs: keep gutters and downspouts clear, remove debris you can reach safely, watch for granule loss and moss, and book a professional inspection when something changes.
What do I get with professional application?
A candidacy assessment, trained and even application, an independently tested system, and a transferable warranty of up to 20 years.
