GoNano silica nanoparticles are less than 100 nanometers in size—about 1,000 times smaller than the pores of a standard asphalt shingle. Thanks to this size, they infiltrate deep into the material by capillarity, before forming stable covalent bonds with the existing structure.

No. Once applied and dry, the GoNano treatment is invisible to the naked eye. It does not alter the color, texture, or appearance of your roof. Only the performance changes: your roof becomes hydrophobic, UV resistant, and structurally reinforced.

Yes. GoNano is manufacturer-certified and impact-rated to UL 2218 (Class 1-4) standards. The treatment is approved for residential and commercial use in Canada, with a manufacturer's written warranty provided to each customer.

None. The GoNano formulation contains no hazardous VOCs (volatile organic compounds), no toxic solvents, and no high-risk WHMIS-classified products. Application does not require house evacuation or special protection for occupants. Treatment residues are biodegradable.

The warranty period depends on the age and condition of your roof at the time of treatment. The covalent bonds formed by the nanoparticles are chemically stable and resistant to freeze-thaw cycles, UV radiation, and acid rain, which allows the manufacturer to guarantee the protection in writing for an extended period.

Yes. Flat roof elastomeric membranes (TPO, EPDM, modified bitumen elastomer) are fully compatible with GoNano treatment. Nano-silica strengthens the membrane, waterproofs joints, and slows down UV-induced delamination. Ideal for income property owners, condominium associations, and commercial managers.
