Is Your Roof a Candidate for Roof Rejuvenation?
Your roof is likely a candidate for rejuvenation if it is an asphalt-shingle roof that is aging but still structurally sound: losing granules, fading, or stiffening, but not leaking or falling apart.
What Makes a Roof a Good Candidate
The best candidates share these traits:
Asphalt shingles. Rejuvenation is formulated for asphalt-shingle roofs.
Aging signs, structure intact. Granule loss, color fading, minor curling, or brittleness are the signs your roof is aging, but the decking underneath is solid.
Past the early years, before failure. Old enough to be drying out, but not so far gone that it is leaking.
No active leaks. Isolated, repairable issues can sometimes be handled first; widespread leaks cannot.
In short: the roof is tired, but not finished. That is when rejuvenation delivers the most value.
What Disqualifies a Roof
Rejuvenation is not a fix for a roof that has already failed. These generally rule it out:
Active, widespread leaks.
Widespread missing, broken, or badly deteriorated shingles.
Rotted or soft roof decking, or structural sagging.
A roof at the true end of its structural life.
Very new roofs, because they do not need it yet.
An honest contractor will tell you if your roof falls here and point you to repair or replacement instead. Anyone who says “yes” to every roof is selling, not assessing.
The Sweet Spot: Aging but Sound
There is a wide middle ground between “brand new” and “needs replacing,” and most roofs spend years there. In that window, the shingles have lost some of the oils that keep them flexible but the roof still does its job.
Treating it then restores flexibility and water resistance and extends usable life for years, at a fraction of roof rejuvenation cost vs. replacement. Miss the window and let the roof fail, and your only option becomes the expensive one.
Being a candidate today doesn’t mean the clock stops. Periodic retreatment is what keeps a roof on the “aging but sound” side of the line, part of GoNano’s long-term push toward 30 to 45 year roof lifespans.
Does My Roof’s Age Matter?
Less than you would think, because condition matters more than age. A well-maintained older roof can be a strong candidate, while a neglected younger one in a harsh climate may not be.
That is also why there is not one product for every roof: a certified installer matches the system to your roof’s condition, NuRoof Fortify for good-to-fair roofs, NuRoof Revive for more aged roofs, and NuRoof Boost as a cost-effective option, rather than treating every roof the same way.
Knowing your roof is a candidate is only half the answer. From there, a Certified GoNano Contractor still has to match it to the right system, since a roof in fair shape doesn't need the same treatment as one that's more heavily aged.
How the assessment works
A Certified GoNano Contractor inspects your roof, confirms whether it is a candidate, matches the right system, and gives you an exact quote, then, if you proceed, installs the treatment and issues a transferable warranty.
GoNano’s 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 application carries a warranty up to 20 years, 100% non-prorated on the full treatment.
Confirm the roof type
Check that it is an asphalt-shingle roof, which is what rejuvenation is formulated for.
Look for aging-but-sound signs
Granule loss, fading, minor curling, or brittleness with the decking still solid are good signs.
Rule out failure
Active widespread leaks, missing shingles, rotted decking, or sagging disqualify a roof.
Weigh condition over age
Judged by its condition, not just its years, because a well-kept older roof can still qualify.

The Bottom Line
If your asphalt roof is aging but structurally sound, it is very likely a candidate, and treating it now is the difference between extending the roof you have and paying to replace it later. If it is already failing, a good contractor will tell you honestly. Either way, the next step is the same.
