Your roof takes a beating. Here in Montreal, it endures freeze-thaw cycles, ice storms, heavy snow loads, scorching summer UV, and driving rain. Over time, that punishment degrades your shingles and shortens your roof lifespan. But a full roof replacement costs $8,000 to $20,000 or more.
GoNano nano-ceramic roof coating is a proven alternative that can extend your roof life by years at a fraction of the replacement cost. As a certified GoNano dealer in Montreal, we apply this advanced coating to protect residential and commercial roofs across the Greater Montreal area. Here are five signs your roof is ready for it.
1. Visible Granule Loss on Your Shingles
Check your gutters and downspouts. If you see a buildup of coarse, sand-like granules, your shingles are shedding their protective layer. Those granules are your first line of defence against UV radiation. Once they go, the underlying asphalt deteriorates quickly.
Why GoNano helps: The nano-ceramic coating creates a new protective barrier over the exposed shingle surface, blocking UV and moisture penetration even after granule loss has started.
2. Shingles Are Curling or Buckling
When shingle edges start to curl upward or the centres buckle, it means the material is drying out and losing flexibility. This is a natural aging process, but it accelerates moisture infiltration and wind damage.
Why GoNano helps: Applied before curling becomes severe, GoNano seals the shingle surface and slows the drying process that causes curling in the first place.
3. Your Roof Is 10 to 15 Years Old
Most asphalt shingle roofs in Quebec are rated for 20 to 30 years, but real-world performance is often shorter due to our extreme climate. The 10 to 15 year mark is when preventive action makes the most financial sense.
Why GoNano helps: Applying GoNano at the 10 to 15 year mark can extend your roof effective life significantly, potentially saving you from a $15,000+ replacement for years to come.
4. Dark Streaks or Algae Growth
Those dark streaks running down your roof are usually Gloeocapsa magma, a type of blue-green algae that feeds on the limestone filler in shingles. While it looks like a cosmetic issue, it actually accelerates granule loss and shingle deterioration.
Why GoNano helps: The nano-ceramic coating creates a surface that resists algae and moss growth, keeping your roof cleaner and healthier.
5. Rising Energy Bills
A degraded roof loses its reflective and insulating properties. If your heating or cooling costs have crept up without other explanation, your roof may be part of the problem.
Why GoNano helps: The ceramic particles in GoNano reflect solar radiation, which can measurably reduce attic temperatures in summer and ease the load on your HVAC system.
