Stunning result after 12 years

Our technician arrived at 8 AM and left at 4 PM. The result is amazing—our 12-year-old roof now looks brand new. 10-year warranty in hand.

Savings of over $13,000

I had replacement quotes around $18,000. GoNano cost me a fraction of that with a written manufacturer's warranty. Easy decision.

No dust, impeccable service

No dust, no smell, no one bothered in the house. The technicians are clean and professional. I recommend them to all my neighbors.

$45,000 in savings on 3 buildings

Owner of a 12-unit building. GoNano treated all three roofs in two days. Saved over $45,000 compared to replacement.

Professional technicians, perfect result

Two very clean, very efficient technicians. They explained everything before starting. My 8-year-old roof looks new. I highly recommend them to all my neighbors.

We avoided $22,000 in replacement costs

Contractors told me I had no choice but to replace the roof. Nano Solution inspected, treated, and provided a manufacturer's warranty. Two years later, zero problems.

From first call to warranty in one week

From the first call to the completion of the work, everything happened in less than a week. Inspection on Monday, treatment on Wednesday, warranty certificate handed over that same evening. Excellent.

Eco-friendly treatment, family reassured

With young children and pets, I had concerns. The technician reassured me: no toxic products, no evacuation required. We stayed home all day.

14-year-old roof like new

My roof was 14 years old and starting to lose granules. After the NuRoof Revive™ treatment, the result is incredible. 10-year manufacturer's warranty — I couldn't ask for more.

Owner of three buildings — massive savings

Three buildings treated in three days. I would have spent over $60,000 on replacement. GoNano treatment solved everything for a fraction of the price, with manufacturer warranties on each building.

No more worries about winter

Our winters are harsh in the Outaouais region. Since the GoNano treatment, no leaks, no detached tiles. The technician explained to us that the nanoprotection repels water and is frost-resistant. I sleep soundly.

Homeowners association — unanimous decision

Our syndicate was wavering between GoNano and a complete replacement at $95,000. After the technician's presentation, the vote was unanimous. Treatment completed, warranty provided — the co-owners are delighted.
