Cold weather doesn’t just sit on your roof, it works against it. Water seeps into tiny cracks and gaps, freezes, expands, and pries those cracks wider; then it thaws and does it again. Over a winter, those repeated freeze-thaw cycles can turn a hairline crack into a real leak. Add wind, snow load, and ice, and winter is the season most likely to expose a roof’s weak points. Aging shingles that have lost their flexibility are the most vulnerable of all, because brittle shingles crack instead of flex, and there is independent testing behind it.
Work through these before the first hard freeze:
They break under ice and snow and scrape granules off shingles.
Poor ventilation is the main cause of ice dams (more below).
If your roof is aging but structurally sound, fall is an ideal window to rejuvenate it, restoring the flexibility that helps shingles flex through freeze-thaw cycles instead of cracking. GoNano’s Structural Roof Rejuvenation replenishes the oils aging shingles lose and adds nano reinforcement that bonds with the shingle at the molecular level. It’s applied in dry conditions above freezing, so scheduling before the deep cold matters.
The system is backed by more than $1 million in independent testing, including a Green Center (now Impact Chemistry) test in which a 15-year-old roof treated with NuRoof Revive outperformed a roof with brand-new shingles, plus UL 2218 Class 4 (impact), ASTM D3161 Class F (wind, rated to 110 mph), and UL 790 Class A (fire). A single GoNano application carries a warranty up to 20 years, 100% non-prorated on the full treatment, and transferable. A Certified GoNano Contractor can tell you whether your roof is a candidate.
Structural Roof Rejuvenation works best when paired with a clear understanding of why roofs fail and what the alternatives cost. If you’re evaluating ice dam damage, you’ve likely come across everything from heat cables to full roof replacement. The guides below address the most common recommendations and explain what may actually be causing the problem.
Yes. A trained inspector catches aging, damage, and ventilation issues you can’t see from the ground, and tells you whether your roof needs treatment, repair, or just routine prep.
