Yours Might Not Need
Replacing.
Most aging asphalt roofs show wear not because they've failed, but because they've lost the protective properties that keep them performing.
Brittleness and Cracking
Shingles lose flexibility with age, becoming brittle and prone to cracking in Ontario's freeze-thaw cycles.
UV and Weather Damage
Sun, hail, rain, and wind strip away the oils that keep shingles flexible and waterproof, cutting years off your roof.
There is another way.
Introducing NanoShield
Molecular-level roof restoration. Powered by GoNano.
NanoShield uses siloxane-based Si-O-Si nanotechnology that bonds with your shingle at the molecular level. It's not a coating that sits on top, it penetrates, reinforces, and restores from within.
The result: a hydrophobic barrier that repels water, blocks UV, and restores the flexibility that age and weather have stripped away. 100% breathable. Fire-rated. Eco-friendly. Safe for your family.
