⸻ Myths vs. Facts

Roof rejuvenation is widely misunderstood. It's not a coating, it's not a scam, and with GoNano it doesn't require repeat reapplications. Because the category is newer and unregulated, myths spread easily. Here are the most common ones, and the facts that clear them up.

It's the opposite of a surface coating. Structural Roof Rejuvenation is a penetrating treatment that restores the shingle itself, replenishing the oils it loses with age and adding nano-penetrating reinforcement that bonds with the shingle at the molecular level. A coating sits on top; rejuvenation works into the shingle.

The mechanism is real and tested. Aging shingles fail because they dry out and lose flexibility; restoring those oils restores flexibility. GoNano's system is backed by more than $1 million in independent testing, including a Green Center (now Impact Chemistry) result where a 15-year-old treated roof outperformed a roof with brand-new shingles, plus UL 2218 Class 4 (impact), ASTM D3161 Class F (wind, 110 mph), and UL 790 Class A (fire).

Not with GoNano. Some soy and bio-oil products are built around repeat reapplications, but a single GoNano application is warrantied up to 20 years, with no re-dosing schedule to reach the term.
No, and an honest provider will tell you so. Rejuvenation is for roofs that are aging but structurally sound. A roof that's actively leaking or failing needs replacement, and a Certified GoNano Contractor will say when your roof isn't a candidate.
They're not. Most soy and bio-oil products do oil replenishment only. GoNano does that and adds nano reinforcement, and backs it with a longer, non-prorated, transferable warranty. Judge any product on independent testing, warranty structure, and certified application.
GoNano's warranty is written, 100% non-prorated on the full treatment (it doesn't shrink year over year), transferable to the next owner, and valid when installed by a Certified GoNano Contractor. Non-proration is the detail most warranties don't have.
The opposite. Replacing a sound roof sends 1–3 tons of shingle waste to the landfill; rejuvenation restores the roof you have and sends none. The most sustainable roof is the one you don't tear off.
You can buy a DIY spray, but you can't DIY the warranty, the candidacy assessment, or safe, even professional application. Those are what make the up-to-20-year, transferable result real.

Most roof rejuvenation myths come from confusing it with coatings, short-term products, or DIY sprays. The facts: it’s a penetrating, independently tested treatment, warrantied up to 20 years from a single application, for roofs that are aging but sound. If you’re still unsure, the honest test is an assessment.
Find a Certified GoNano Contractor near you to separate fact from fiction for your roof.
A full tear-off is one of the most expensive and wasteful choices a homeowner can make, so it’s worth knowing the numbers before you commit. The guides below break down what a replacement really costs in 2026, how restoration compares on price and lifespan, and how to get more years out of the roof you already have.
No. Aging shingles fail by drying out and losing flexibility; restoring their oils restores flexibility. GoNano's system is backed by over $1M in independent testing and a result where a 15-year-old treated roof outperformed brand-new shingles.
No, it's the opposite. It's a penetrating treatment that restores the shingle itself, rather than a film that sits on top like a coating.
Yes, on an aging-but-sound roof. It replenishes the oils shingles lose and adds nano reinforcement, with independent testing to recognized impact, wind, and fire standards.
Not with GoNano. A single application is warrantied up to 20 years. Some other products are built around repeat reapplications.
No. It's for roofs that are aging but structurally sound. A leaking or failed roof needs replacement, and an honest provider will tell you when your roof isn't a candidate.
No. Most do oil replenishment only; GoNano adds nano reinforcement and a longer, non-prorated, transferable warranty. Compare on testing, warranty, and certified application.
It's real: written, 100% non-prorated on the full treatment, transferable, and valid when installed by a Certified GoNano Contractor.
No, it's more sustainable than replacement. It restores your existing roof instead of sending 1–3 tons of shingles to the landfill.
You can buy a DIY spray, but you can't DIY the warranty, the candidacy assessment, or safe, even professional application, which is what makes the result and warranty real.
Generally, a non-invasive restoration treatment doesn't replace or interfere with shingle structure, but confirm specifics with a Certified GoNano Contractor for your roof and manufacturer.
