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 and Wood Saver 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 10 to 15 years.

Real Cranbrook Homeowners

Stories from 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 15 more years. No mess, no disruption, and a fraction of what a new roof would have cost.

Why Gonano

Trusted by Your Neighbours

🛡️

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–$40,000. 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.

📋

We Stand Behind It

Every job comes with an up-to-15-year warranty — and if you ever sell your home, it transfers to the new owners. We're not going anywhere. We live here too.
