How is that different from a roof coating?
Roof coatings — including soy and bio-oil alternatives sold under various brand names — are surface-applied products. They form a film on top of the shingle. Structural Roof Rejuvenation works at a different level: it penetrates the shingle structure and bonds at the nano scale.
i.Where the product works
Coatings sit on the shingle surface. Structural Roof Rejuvenation penetrates into the shingle.
That's why GoNano isn't classified as a coating — it doesn't behave like one.
ii.How long it lasts
Surface coatings typically degrade with the same UV and weather exposure that aged the shingles in the first place. GoNano NuRoof's nano-penetrating bond is protected inside the shingle structure, providing hard warranties of 10–15 years.
iii.What testing exists
GoNano holds UL2218 Class 4impact resistance (the highest rating), ASTM D3161 Class F wind resistance,UL790 Class A fire resistance, IBHS validation, and Impact Chemistry (formerlyGreen Center) certification — all from independent third parties, with $1million invested in the testing program. Soy and bio-oil alternatives vary inwhat independent testing they have published.
iv.What the warranty actually says
A hard warranty means the warranty period is the warranty period. GoNano NuRoof Fortify is 15 years. GoNano NuRoof Revive is 10 years. The warranty is transferable to the next homeowner when the property is sold, which adds resale value. Many surface coatings carry conditional warranties that can be voided by ordinary weather events.
v.What the long-term roof economics look like
A GoNano NuRoof Fortify treatment on a roof under 5 years old is engineered to deliver a 30-year roof life from a single application. GoNano NuRoof Revive on a 6–20 year old roof extends serviceable life by another 10–15 years. With retreatment cycles, a roof can stay in service for 30–45 years instead of being replaced at 15–20.

How to know which one a contractor is offering
Before a contractor applies anything to a roof, ask three questions:
1.Is this product nano-penetrating, or does it stay on the surface?
2.What independent third-party testing exists for it — and can I see the test reports?
3.Is the warranty hard or conditional, and is it transferable when I sell the home?
These three questions separate Structural Roof Rejuvenation from surface coatings quickly, regardless of how the product is marketed.

Frequently asked questions
Is Structural Roof Rejuvenation a type of roof coating?
No. Roof coatings aresurface-applied. Structural Roof Rejuvenation penetrates the shingle structureand bonds at the nano level. The two products work at different layers and aretested under different criteria.
Does GoNano contain soy or bio-oil?
GoNano's NuRoof products are nano-penetrating restoration products. They use minimal bio-oil only as a complement to the nanostructure — the active mechanism is the molecular bond, not a surface oil application.
Where can I find a Certified GoNano Contractor?
GoNano has a network of 420+Certified Contractors across North America. Use the contractor locator on gonano.com (US) or gonano.ca (Canada) to find one in your market area.
Why does GoNano have $1 million in testing?
Independent third-party testing (UL, ASTM, IBHS, Impact Chemistry) is the only way to validate performance claims. GoNano invested at this scale to back the hard warranty and to give Certified GoNano Contractors verifiable evidence to share with property owners.
How does the warranty compare?
GoNano NuRoof Fortify carries a 15-yearhard warranty. GoNano NuRoof Revive carries a 10-year hard warranty. Both aretransferable. Most surface coating warranties are shorter and may beconditional on weather, maintenance, or other factors.
