"The difference is structural: coatings sit on top. Structural Roof Rejuvenation bonds within the shingle."
Structural Roof Rejuvenation is a category of roof restoration that uses nano-penetrating technology to bond with the shingle's molecular structure, restoring flexibility and adding weather resistance from within the shingle — not on top of it. GoNano established this category after Dragons' Den investors saw what the technology could do — three out of five made offers. Today, GoNano remains the only company with $1 million in independent third-party testing across UL, ASTM, and IBHS standards.

$1 million invested in independent third-partytesting across four credentialing bodies.
"Independent testing is about real world performance. Standards like impact, wind, and fire resistance help show how a roof will hold up when it actually matters. When a product has been evaluated against recognized benchmarks, homeowners can make better decisions based on accurate data, not empty words."
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.
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.
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.
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.
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.
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.
Before a contractor applies anything to a roof, ask three questions:
These three questions separate Structural Roof Rejuvenation from surface coatings quickly, regardless of how the product is marketed.
Structural Roof Rejuvenation works best when paired with a clear understanding of why roofs fail and what the alternatives cost. For homeowners researching their options, the related guides below cover the most common questions.
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.
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.

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.
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.
