The difference is structural: coatings sit on top of the shingle, Structural Roof Rejuvenation bonds inside it.
Category Definition Guide
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 Dragon's 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.
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.
1. 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.
2. How long it lasts: Surface coatings typically degrade with the same UV and weather exposure that aged the shingles in the first place. NuRoof's nano-penetrating bond is protected inside the shingle structure, providing hard warranties of 10–15 years.
3. 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.
4. What the warranty actually says: A hard warranty means the period is guaranteed. NuRoof Fortify is 15 years. NuRoof Revive is 10 years. Both are fully transferable, adding significant resale value to your home.5. Long-term roof economics: A NuRoof Fortify treatment on a young roof (< 5 years) is engineered to deliver a 30-year life. NuRoof Revive extends the life of older roofs (6–20 years) by another 10–15 years.
5. What the long-term roof economics look like: A NuRoof Fortify treatment on aroof under 5 years old is engineered to deliver a 30-year roof life from asingle application. NuRoof Revive on a 6–20 year old roof extends serviceablelife by another 10–15 years. With retreatment cycles, a roof can stay inservice for 30–45 years instead of being replaced at 15–20.

Before a contractor appliesanything 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 separateStructural Roof Rejuvenation from surface coatings quickly, regardless of how the product is marketed.
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.
GoNano has a network of 420+Certified Contractors across North America. Use the contractor locator ongonano.com (US) or gonano.ca (Canada) to find one in your market area.
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.
NuRoof Fortify carries a 15-yearhard warranty. 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.
