Extreme Weather Protection for Asphalt Shingles and Concrete

We've Got You Covered.

Key City Surface Solutions was founded because we had the same concerns you do. We wanted to keep our home — and especially our roof — in the best condition possible by stopping the aging process. Now we help East Kootenay homeowners protect their biggest investment for a fraction of the cost of replacement. Gonano NuRoof, along with Gonano Concrete treatments, use nanotechnology — nano particles that transform the molecular structure of materials to permanently modify their properties, enhance their resistance, and extend their lifespan by up to 20 years.

Stop Replacing. Start Restoring.

See how Gonano's nano-silica technology can add up to 20 years to your existing asphalt shingles — without the cost or waste of a full tear-off.

See The Difference Up Close

Under magnification, an untreated shingle shows granules that have come loose and worn from the surface. Gonano's nano-silica penetrates deep into the shingle and re-locks those granules back into place — rebuilding the structure from within instead of just coating the top.

Why Gonano

Trusted by Your Neighbours

“

Deda had a 15-year-old roof that was still in good shape — but she wanted peace of mind. Rather than wait until it needed replacing, she called us to protect what she had. One treatment, one day, and her roof is now covered for up to 12 more years. No mess, no disruption, and a fraction of what a new roof would have cost.

It Actually Works

We used it on our own roof first. The treatment goes deep into your shingles and protects them from the inside out — no peeling, no coatings, no mess. Just a roof that lasts years longer.

💰

Save Thousands

A new roof in the East Kootenay can run $20,000 or more. Most of our customers protect their existing roof for a fraction of that — with financing as low as $149/month so there's no big hit upfront.
