Sean and Shawn quote the roofs, climb the roofs, and answer the phone. Here's who you're dealing with, and why we do this.
Free. In person. No pressure. If your roof doesn't qualify, we tell you that too.
The guys who quote your roof are the guys who climb it. Sean Lyons and Shawn Kisling are Certified GoNano Contractors based in Auburn Bay, in Calgary's southeast. When you call, you talk to one of us. When the tent goes up on your driveway, we're the ones under it.
We apply the GoNano nano shield to asphalt shingle roofs across Calgary, Airdrie, Cochrane, Okotoks, Chestermere and Strathmore. The same technology protects concrete driveways, cedar fences and decks. One crew, one product family, one straight answer about whether your surface qualifies.

Sean, mid-treatment day in southeast Calgary. Press play and meet the guy who answers the phone.
Sean is the reason this company exists. Hail hit his own roof in 2021 and the insurance shortfall nearly ruined him, so he certified on GoNano to keep his neighbors out of the same trap. He's the voice on the phone and the one walking most of the assessments.
Shawn is the other half of every job. He keeps the company rules honest: show up when promised, clean up before leaving, and give a straight answer even when it's "your roof doesn't qualify." When our reviews name the crew, they name Shawn and Sean. That's the whole crew.
In 2021, hail hit Sean's own roof. That's when he learned something most Calgary homeowners find out the hard way: once a roof is 15 years or older, many insurers depreciate its replacement value to about 25 percent.
So Sean stood there with a $10,000 roof replacement bill in one hand and a $1,500 insurance check in the other. His roof's depreciated value came to $2,500, minus a $1,000 deductible. A surprise $8,500 expense almost ruined him.
Nobody warned him. Nobody told him a 15-year-old roof could be protected for a fraction of that, years before the storm.
That's the whole company. Sean started Nano Shield so his neighbors never get caught the way he did: protect the roof you have, keep it insurable, and skip the five-figure surprise. A warranty of up to 15 years, real posted pricing, done in under one day.
"Such a wonderful experience working with Shawn and Sean! These guys know their stuff, show up when they say they are going to, and get the job done."
Anyone can buy a sprayer. Certification is what makes the warranty real. Here's what it means for you:
Licensed, insured, and safe to have on your roof:
Free. No pressure. You get a straight answer and photos of your own roof.
The GoNano sprayer, up close. The treatment penetrates the shingle and cures into a hard shield.
You may have seen this technology on Dragon's Den before we ever applied it here. GoNano technology, as seen on Dragon's Den. It's the same treatment we apply to Calgary roofs, driveways and fences. We're the certified local crew behind the sprayer.

Every job gets photographed from the air. Yours would too.
