Question 1

What is GoNano roof rejuvenation?

Accepted Answer

GoNano is a USDA bio-based nanotechnology treatment that penetrates asphalt shingles at a molecular level, restoring the oils and flexibility lost to UV exposure and weathering. It extends roof life by 10–15 years and prevents costly replacement.

Question 2

How much does roof rejuvenation cost in BC?

Accepted Answer

GoNano roof rejuvenation costs approximately $2 per square foot of roof area. For a typical BC home, treatment ranges from $2,600 to $6,500 — compared to $15,000–$30,000 for a full roof replacement.

Question 3

How long does the GoNano treatment last?

Accepted Answer

GoNano treatment comes with a 10-year warranty and is designed to extend your roof's serviceable life by 10–15 years when applied to qualifying asphalt shingles.

Question 4

What types of roofs qualify for rejuvenation?

Accepted Answer

Asphalt and fiberglass shingles between 7–20 years old are the ideal candidates. Roofs with active leaks, missing shingles, or structural damage may need repairs first. We offer a free assessment to determine eligibility.

Question 5

Is GoNano safe for the environment?

Accepted Answer

Yes. GoNano is USDA Certified Bio-Based, made from plant-derived oils. It is non-toxic, safe for pets and children after application, and does not harm surrounding vegetation or waterways.

Question 6

My insurance says my roof is too old — what are my options in BC?

Accepted Answer

GoNano NuRoof™ rejuvenation costs $1,500–$4,500 and comes with a 10-year manufacturer warranty you can provide to your insurer — compared to $15,000–$25,000 for full replacement. The warranty certificate is often exactly what BC insurers need to maintain or reinstate coverage.

Question 7

Can roof rejuvenation help me pass a roof inspection for insurance without replacing my shingles?

Accepted Answer

In many cases, yes. GoNano NuRoof™ re-bonds granules, eliminates moss and algae, restores shingle flexibility, and provides a 10-year warranty certificate and photo report — the documentation most BC insurers require.

Question 8

Is roof rejuvenation worth it in BC?

Accepted Answer

For most BC homeowners with a structurally sound aging roof, yes. Rejuvenation costs 80–90% less than replacement, extends roof life 10–15 years, comes with a 10-year warranty, and satisfies many insurance requirements. The free assessment will confirm if your roof qualifies.

Question 9

Can you restore granules on asphalt shingles and stop them from drying out?

Accepted Answer

Yes. GoNano's nano-silica particles penetrate the asphalt matrix, restoring the molecular bonds that hold granules in place and replenishing the oils that keep shingles flexible and waterproof.

Question 10

Do you serve my area in the Lower Mainland?

Accepted Answer

NanoShieldBC serves 11 cities across Metro Vancouver and the Fraser Valley: Vancouver, Surrey, Burnaby, Richmond, Coquitlam, Langley, Abbotsford, North Vancouver, West Vancouver, Delta, and Maple Ridge.
