Example of ice buildup along roof eaves during a Winnipeg freeze-thaw cycle.
Winnipeg Winters Are Brutal on Roofs
Snow builds up.
The attic warms the roof deck.
Snow melts.
Water runs down to the cold eaves.
It refreezes.
That frozen ridge becomes an ice dam.
Now melting water has nowhere to go.
It backs up under shingles.
That’s how leaks start.
What Ice Dams Actually Do to Asphalt Shingles
Ice dams don’t just cause leaks. They accelerate roof aging.
Repeated freeze-thaw cycles:
• Make shingles brittle
• Loosen granules
• Break down seal strips
• Increase edge curling
• Speed up deterioration
In Winnipeg, this happens every winter.
Important: What Causes Ice Dams
Ice dams are primarily caused by:
• Poor attic insulation
• Uneven roof temperatures
• Inadequate ventilation
NuRoof does not replace ventilation or insulation.
What it does is protect the roofing material from the damage ice dams create.
That difference matters.
How GoNano NuRoof Revive Helps in Winter
GoNano NuRoof Revive penetrates aging asphalt shingles and restores lost flexibility.
Flexible shingles are less likely to crack during freeze-thaw cycles.
They maintain stronger granule adhesion.
They resist premature edge curling.
Result:
Your roof handles winter stress better.
How GoNano NuRoof Fortify Adds Protection
GoNano NuRoof Fortify creates a hydrophobic barrier within the material.
Water is repelled instead of absorbed.
Less moisture absorption means less internal freeze expansion.
That reduces long-term deterioration from repeated melt and refreeze cycles.
Result:
Improved resistance to winter moisture damage.
What This Means for Winnipeg Homeowners
Ice dams may still form.
But your shingles don’t have to deteriorate faster because of them.
NuRoof systems help extend roof life 10–15 years at a fraction of replacement cost.
That’s real protection.
