Millions of nanoparticles. Zero roof replacements.
Your roof probably has years of life left in it. We apply a nano-penetrating shield that adds 10 to 15 years for about a quarter of what a reroof costs. Installed in under one day.

Tell us where the roof is. We call you back to set a time.
Most rejuvenation companies in Calgary warrant their spray for 5 years. GoNano backs ours for up to 15. It's in writing, and it transfers if you sell.
Nobody else in Calgary posts their numbers. A typical 2,000 sq ft roof runs about $3,000. Reroofing the same house runs $13,000. See the full pricing table.
Most sprays are bio-oils that soften shingles for a few years. Our nano-penetrating treatment hardens the surface against UV and improves impact resistance to hail and winds. Backed by $1 million in independent testing. See the difference.
Repairs first, then the treatment. Most homes are done before dinner. You don't need to leave the house.

The same nanotechnology protects more than shingles. Whatever the surface, the job starts with a free in-person assessment.
The flagship. Add 10 to 15 years to an asphalt shingle roof at a quarter of replacement cost.
Roof rejuvenation in Calgary →
Lifted shingles, small leaks, storm damage. We fix problem spots first, on every job.
Roof repair in Calgary →
Membrane and flat roofs age fast under Calgary sun. Coat them without a tear-off.
Commercial roof coating →Asphalt shingles dry out. Calgary's UV, chinook freeze-thaw cycles and wind pull the oils out of them. They curl, crack, and shed granules. That's when most people get quoted $13,000 for a reroof.
Here's the thing. The shingle isn't used up. It's just dry and brittle.
Most companies spray a bio-oil that softens shingles again for a few years. We do something different. The patented GoNano treatment penetrates the shingle and cures into a hard shield. It seals the granules down, repels water, and improves impact resistance to hail and winds.
A real Nano Shield job site in Calgary. The tent banner says it straight: impact resistance to hail and winds, stops loss of granules.
The treatment soaks deep into every shingle.
Hardened against UV, water, hail and wind.
