Protecting BC homes
one surface at a time.
We're a Certified GoNano Applicator serving homeowners and property managers across BC. We started this company because we kept seeing roofs get replaced that didn't need to be — and we wanted to offer a better option for the ones that still had life left.
Our Mission
Don't replace it.
Restore it.
Too many BC homeowners are told their roof needs to be replaced when it doesn't. Replacement is expensive, disruptive — and in many cases, premature.
We started NanoShieldBC.ca because we believe there's a smarter option for roofs that still have life left. GoNano nanotechnology can restore and protect qualifying asphalt shingles at a fraction of replacement cost.
That said — not every roof qualifies. Our job is to give you an honest assessment first. If treatment makes sense for your roof, we'll tell you exactly what to expect. If it doesn't, we'll tell you that too.
Years of additional roof life in qualifying treated cases — not a guarantee for every roof
Serving homeowners and property managers across British Columbia — we know the local climate
Exclusively focused on asphalt shingle roof rejuvenation — we do one thing and do it right
We'll tell you if your roof doesn't qualify — even if that means we don't get the job
Powered by GoNano technology
GoNano is an advanced nanotechnology company specializing in surface treatment formulas that penetrate and bond at a molecular level. Their products are engineered for durability, breathability, and long-term protection — and have been independently tested under recognized standards including UL and ASTM.
As a Certified GoNano Applicator, NanoShieldBC.ca is trained and authorized to apply these products professionally. That certification is required to issue the manufacturer warranty — and it means we're accountable to GoNano's standards, not just our own.

How We Work
What you can expect from us
Certified GoNano Applicator
We are trained and authorized to apply GoNano nanotechnology products. That certification matters — it's what backs the 10-year manufacturer warranty on every qualifying treatment.
We Tell You If It Won't Work
Not every roof qualifies. If your roof is too far gone, we'll say so — and point you toward the right next step, even if that means a full replacement. We'd rather lose a job than give you false hope.
Built for BC's Climate
The rain, the moss, the freeze-thaw cycles — we know what BC roofs go through. Our assessments and treatment recommendations are made with local conditions in mind, not a one-size-fits-all script.
A Real Alternative — When It Applies
GoNano treatment can extend the life of a qualifying roof by 10–15 years at a fraction of replacement cost. But it's not magic. We'll always give you an honest picture of what's realistic for your specific roof.
