Structural Roof Rejuvenation is a professional treatment that restores aging asphalt shingles from within, replenishing the oils they lose over time and adding nanotechnology reinforcement that bonds with the shingle at the molecular level. It extends the service life of a roof for years at a fraction of replacement cost, and it is backed by more than $1 million in independent testing. It is not a coating and not a sealant, nothing sits on top of your shingles.
If you have been researching “roof rejuvenation,” you have probably seen a lot of similar-sounding claims. This guide explains what rejuvenation actually is, how the different approaches work, and what makes Structural Roof Rejuvenation a distinct category.
Asphalt shingles are held together by petrochemical oils that keep them flexible. Sun, heat, rain, wind, and freeze-thaw cycles drive those oils out over time. As the oils deplete, shingles grow brittle, crack, curl, and shed the granules that protect them, the visible signs most homeowners recognize as an “aging” roof.
Roof rejuvenation slows and partially reverses that process. Instead of tearing the roof off, a trained professional treats the existing shingles so they regain flexibility and shed water the way they did when they were newer. Soy and bio-oil rejuvenation products do this by replenishing the depleted oils. It is a real, science-backed restoration principle, and it works within the roof’s remaining structural life.
Structural Roof Rejuvenation starts from that same principle and then adds a second mechanism the oil-only approach does not have.
GoNano NuRoof, GoNano’s Structural Roof Rejuvenation system, works on two fronts at once:
The same restoration principle behind soy and bio-oil rejuvenation — it brings flexibility back to shingles that have dried out.
The result is not a film resting on the surface of your shingles; it is reinforcement built into them. That is why GoNano treats this as its own category, Structural Roof Rejuvenation: it restores like a rejuvenator and reinforces like nothing else in the category.
Both keep aging shingles out of the landfill and both cost far less than replacement. The difference is what happens inside the shingle.
Yes — restores lost flexibility
Yes — restores lost flexibility
Yes — nano-penetrating technology bonds within the shingle
No
Yes UL2218 Class 4 impact, ASTM D3161 Class F wind (110 mph), UL790 Class A fire, Impact Chemistry (formerly Green Center) — treated 15-yr-old roof outperformed brand-new shingles

Structural Roof Rejuvenation
Rejuvenation / treatment
A coating is a film applied on top of a roof to add a surface layer. Coatings can peel, crack, or trap moisture on asphalt shingles, and they are generally intended for flat or low-slope roofs made from other materials.
Structural Roof Rejuvenation is the opposite approach: it penetrates the shingle and works within the asphalt itself. Nothing sits on the surface to peel away. If a contractor describes a treatment as a “coating” or “sealant” for your asphalt shingles, that is a different product doing a different thing.
GoNano has invested more than $1 million in independent, third-party testing of its Structural Roof Rejuvenation system. In one striking result, testing at Green Center (now Impact Chemistry) found that a 15-year-old roof treated with NuRoof Revive outperformed a roof with brand-new shingles. Treated shingles have also earned:
Wind resistance rated to 110 mph.
The top fire-performance classification.
GoNano also appeared on Canada’s Dragon’s Den (Canada’s equivalent of Shark Tank), where the technology drew multiple investment offers. Credentials like these are verifiable, which is what makes them meaningful. A warranty is only as strong as the testing behind it.
A Certified GoNano Contractor assesses your roof and matches the right NuRoof system and coat count to its condition. Warranty terms depend on the system and number of coats:
Warranty up to 20 years plus 5-year hail coverage, 100% non-prorated for the full term, maximum protection for the best-candidate roofs.
Warranty up to 20 years as a two-coat system, or up to 15 years single-coat.
Warranty up to 12 years when applied as a two-coat system with Fortify.
The differentiator to understand: non-proration. Many roof warranties quietly shrink their payout after about year 10. On GoNano’s two-coat systems, coverage stays at 100% for the full term; it does not decline. The warranty is also transferable (see how our warranty works), so it becomes a selling feature if you list your home rather than a question mark for the next owner.
You don’t buy NuRoof off a shelf; you have a Certified GoNano Contractor install it, and the warranty is backed by GoNano and its 420+ contractor network, not by a single individual.
Depending on size, pitch, and materials.
Structural Roof Rejuvenation is a fraction of that and it can extend a roof’s usable life by years, buying time on your terms rather than under emergency pressure. For a full breakdown of the math, see our roof rejuvenation cost vs. replacement comparison once it publishes.
Structural Roof Rejuvenation is designed for asphalt-shingle roofs that are structurally sound but aging showing granule loss, brittleness, color fade, or early curling. It is not a repair for active leaks, missing shingles, or a roof that has already failed. The best way to know if your roof is a candidate is a professional assessment from a Certified GoNano Contractor. It also helps to know the right questions to ask a roofing contractor.
If your roof is starting to show its age, it’s worth having a Certified GoNano Contractor take a look. They’ll walk the roof, give you a straight answer on whether Structural Roof Rejuvenation makes sense for it, and match you with the right NuRoof system for the job, backed by a warranty of up to 20 years and more than $1 million in independent testing. Find a Certified GoNano Contractor near you and get it assessed.
Structural Roof Rejuvenation works best when paired with a clear understanding of why roofs fail and what the alternatives cost. If you’re evaluating ice dam damage, you’ve likely come across everything from heat cables to full roof replacement. The guides below address the most common recommendations and explain what may actually be causing the problem.
Structural Roof Rejuvenation is a professional treatment that restores aging asphalt shingles by replenishing lost oils and adding nanotechnology reinforcement that bonds with the shingle at the molecular level. It extends roof life at a fraction of replacement cost and is not a coating or sealant.
No. A coating sits on top of the roof as a film. Structural Roof Rejuvenation penetrates and works within the shingle, so there is nothing on the surface to peel, crack, or trap moisture.
Warranty terms depend on the system and coat count: up to 20 years for Fortify (two-coat), up to 12 years for Revive, and up to 10 years for Boost. Two-coat systems stay 100% non-prorated for the full term, and the warranty is transferable.
A full replacement commonly costs $8,000 to $25,000 or more. Rejuvenation is a fraction of that and extends the roof’s usable life for years, letting you plan a replacement on your own schedule.
It is designed for asphalt-shingle roofs that are aging but structurally sound — think granule loss, brittleness, or fading. It is not a fix for active leaks or a failed roof. A Certified GoNano Contractor can assess your roof and confirm.
Standard soy and bio-oil rejuvenation replenishes the oils shingles lose as they age. Structural Roof Rejuvenation does that too, then adds nanotechnology reinforcement that bonds with the shingle — protection built into the shingle rather than a surface layer.
For structurally sound but aging asphalt shingles, yes — it restores flexibility and water resistance. GoNano’s system is backed by more than $1 million in independent testing, including UL 2218 Class 4 impact and ASTM D3161 Class F wind (110 mph).
It means the coverage does not shrink over time. Many warranties reduce their payout after roughly year 10; on GoNano’s two-coat systems, coverage stays at 100% for the entire term.
Treated shingles have earned UL 2218 Class 4 (the top impact class, relevant to hail) and ASTM D3161 Class F wind resistance rated to 110 mph in independent testing.
You have a Certified GoNano Contractor install it. They assess your roof, match the right system and coat count to its condition, install the treatment, and issue the transferable warranty backed by GoNano’s 420+ contractor network.
