Everything You Need to Know About GoNano

GoNano uses nanosilica particles that penetrate into asphalt shingles at the molecular level. Unlike traditional coatings that sit on the surface, nanosilica forms a permanent molecular bond within the shingle matrix, restoring flexibility, creating a hydrophobic barrier, and enhancing UV resistance.

Traditional coatings are surface-level products that peel, crack, or wash off over time. GoNano works from within — the nanosilica particles are so small they penetrate the asphalt, creating a permanent modification that cannot be separated from the shingle itself.

Yes. GoNano has been independently tested by CNETE, a Canadian independent laboratory, with over $750,000 invested in testing and certification. The technology has also been featured on Dragons' Den / Dans l'œil du dragon.

Depending on the product and your roof's condition: NuRoof Fortify™ comes with a 15-year non-prorated warranty, NuRoof Revive™ with a 10-year transferable warranty, and Bio-Boost™ with a 5-year warranty.

Absolutely. The nanosilica solution is non-toxic, biodegradable, and safe for surrounding vegetation, pets, and wildlife. Bio-Boost™ is our most eco-friendly option, rated 100% biodegradable.

GoNano works on asphalt shingle roofs, which represent the vast majority of residential roofs in Quebec. It is not designed for metal, slate, clay tile, or flat membrane roofs.

One of our certified inspectors climbs onto your roof and evaluates 6 factors: granule loss, shingle flexibility, roof age, moss/algae presence, curling/cupping, and moisture signs. This gives your roof a Shingle Health Score that determines the recommended treatment.

Most residential roofs are completed in a single day. Our team arrives in the morning, prepares the surface, applies the nanosilica solution using professional spray equipment, and you're rain-safe within 24 hours.

Not necessarily, but we recommend being available for the start and end of the application so we can walk you through what was done and answer any questions.

The treatment begins working immediately upon application. Full molecular bonding completes within 48–72 hours. You won't see a dramatic visual change — the protection happens at the molecular level within the shingle.

The treatment is rain-safe within 24 hours of application. This is why we only apply during warm, dry conditions (typically May through October in Quebec). Light rain after 24 hours will not affect the treatment.

Average treatment cost is $3,500–$6,000, depending on roof size, condition, and recommended product. Compare this to full roof replacement at $15,000–$30,000. Your free inspection includes a detailed, no-surprise quote.

Yes! NuRoof Fortify™ and NuRoof Revive™ warranties are fully transferable to new homeowners, which adds value to your property at sale time.

The warranty covers the performance of the nanosilica treatment — specifically the hydrophobic barrier, UV protection, and structural enhancement. It does not cover damage from extreme events (fallen trees, ice dams from structural issues) or normal end-of-life deterioration for roofs near replacement age.

No. GoNano is a one-time application. Because the nanosilica bonds permanently at the molecular level, it cannot be washed off, peeled, or worn away. One treatment provides the full warranty period of protection.
