Quick answerRoof rejuvenation isn't a scam or a coat of paint: Gonano's treatment soaks into the shingle, is independently tested for impact, wind and fire, and is applied once with a written, transferable warranty of up to 20 years. It is not for every roof, though; it suits aging but sound shingles, and a leaking or failing roof still needs replacing.

November is when a lot of East Kootenay homeowners take a hard look at the roof. The leaves are down, the first snow has dusted Cranbrook and Kimberley, and anyone thinking about next season's roof work starts reading up. That is also when we hear the same handful of doubts about roof rejuvenation. Here are the myths that come up most, and the facts behind them.

Myth: It's Just a Coating or Paint

This is the most common one. Gonano's roof treatment does not sit on top of the shingle like paint. It is a penetrating nano-silica treatment: it replenishes the oils asphalt shingles lose to sun and age, and it adds nano reinforcement inside the shingle itself. That is why a treated roof regains flexibility instead of just looking shinier for a season.

Myth: It's a Scam and Can't Work

Gonano's roof treatment is independently tested to the top ratings for impact (UL 2218 Class 4), wind (ASTM D3161 Class F, 110 mph or about 177 km/h) and fire (UL 790 Class A). In testing at the Green Center (now Impact Chemistry), a 15-year-old roof that had been treated outperformed a roof with brand-new shingles. We cover the ratings in more detail in how a treated roof stands up to hail, wind and fire.

Myth: You Have to Reapply Every Couple of Years

One application is the plan. A Gonano treatment is backed by a warranty of up to 20 years, with no schedule of top-ups. That warranty is written, non-prorated and transferable, and it is valid when a certified Gonano contractor does the installation.

Myth: Any Roof Can Be Rejuvenated

Not true, and we will tell you so. Rejuvenation suits roofs that are aging but still structurally sound. If a roof is actively leaking, has soft decking or large areas of missing shingles, it needs replacing, and we refer that work to our partner AdaptiBuild. Our five-step candidacy check explains what we look for, and a free roof assessment settles it.

Myth: All Roof Treatments Are the Same

Most soy and bio-oil alternatives only put oil back into the shingle. Gonano's treatment does that and adds nano-silica reinforcement, and it comes with a longer, non-prorated, transferable warranty.

Myth: It's Bad for the Environment

The opposite. Replacing an asphalt roof sends roughly one to three tons of shingle waste to the landfill. Keeping a sound roof working for years longer avoids that tear-off altogether.

Myth: You Can Just Do It Yourself

Consumer roof sprays exist, but they can't give you the candidacy check, the professional application or the transferable warranty. We went through the trade-offs last week in DIY vs. professional roof treatment.

The real question isn't whether rejuvenation works. It's whether your roof is still a good candidate. For an average home, a roof rejuvenation from Key City runs $2,500 to $6,000, about 80% less than the $20,000 or more for a new roof, and financing starts at $149 a month.

Treatment needs dry weather above freezing, so over the winter is a good time to get your roof assessed and on the list for spring, from Fernie and Sparwood to Creston and Invermere.

Frequently Asked Questions

Is roof rejuvenation a scam?

No. Gonano's roof treatment is independently tested to UL 2218 Class 4 for impact, ASTM D3161 Class F for wind and UL 790 Class A for fire, and in testing at the Green Center (now Impact Chemistry) a treated 15-year-old roof outperformed new shingles.

Is Gonano's roof treatment just a coating?

No. It isn't a coating or paint. It is a penetrating treatment that replenishes the oils shingles lose with age and adds nano-silica reinforcement inside the shingle, rather than sitting on top of it.

How often does a roof treatment need to be reapplied?

A single Gonano application is backed by a warranty of up to 20 years. There is no schedule of top-ups every couple of years.

Can any roof be rejuvenated?

No. Rejuvenation suits asphalt shingle roofs that are aging but still structurally sound. A roof that is leaking or failing needs replacement, which is why every job starts with a free roof assessment.

Does rejuvenation void my shingle manufacturer's warranty?

The treatment is non-invasive and generally does not interfere with the shingle's structure, but confirm the details with your certified Gonano contractor and your shingle manufacturer.
