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.

How Roof Rejuvenation Works

sphalt 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.

What Makes Structural Roof Rejuvenation Different

GoNano NuRoof, GoNano's Structural Roof Rejuvenation system, works on two fronts at once:

1

It replenishes depleted oils.

The same restoration principle behind soy and bio-oil rejuvenation — it brings flexibility back to shingles that have dried out.

2

It adds nanotechnology reinforcement.

What the oil-only approach doesn't have — GoNano's nano-penetrating technology bonds with the shingle at the molecular level, so the reinforcement becomes part of the shingle rather than a layer sitting on top.

The result is ot 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.

Structural Roof Rejuvenation vs. Soy and Bio-Oil Rejuvenation

Both keep aging shingles out of the landfill and both cost far less than replacement. The difference is what happens inside the shingle.

Factor Structural Roof Rejuvenation (GoNano NuRoof) Soy & Bio-Oil Rejuvenation
Oil replenishment Yes — restores lost flexibility Yes — restores lost flexibility
Nano reinforcement Yes — nano-penetrating technology bonds within the shingle No
Independent testing $1M+: 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 Varies; limited independent verification
Warranty Up to 20 years, 100% non-prorated on 2-coat systems, transferable Typically shorter, often prorated

Is It a Coating? No — Here's the Distinction

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.

What the Independent Testing Shows

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:

UL 2218

Class 4

The highest impact-resistance class, relevant to hail damage and your roof.

ASTM D3161

Class F

Wind resistance rated to 110 mph.

UL 790

Class A

The top fire-performance classification.

GoNano independent testing credentials: UL 2218 Class 4, ASTM D3161 Class F, UL 790 Class A, and Green Center (now Impact Chemistry) results

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.

The Products: Matching the System to Your Roof

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:

Premium

NuRoof Fortify Elite

Two-coat, premium tier

Warranty up to 20 years plus 5-year hail coverage, 100% non-prorated for the full term, maximum protection for the best-candidate roofs.

NuRoof Fortify

Good-to-fair roofs

Warranty up to 20 years as a two-coat system, or up to 15 years single-coat.

NuRoof Revive

Aging roofs

Warranty up to 12 years when applied as a two-coat system with Fortify.

NuRoof Boost

Cost-effective life extension

Warranty up to 10 years as a two-coat system with Fortify, or 3–5 years single-coat.

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.

How Much Does It Cost Compared to Replacement?

Full Roof Replacement

$8,000–$25,000+

Depending on size, pitch, and materials.

Structural Roof Rejuvenation

A fraction of that

And it extends a roof's usable life by years.

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.

Who Is It For?

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.

Frequently Asked Questions

What is Structural Roof Rejuvenation?

keyboard_arrow_down

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.

How is it different from regular roof rejuvenation?

keyboard_arrow_down

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.

Is Structural Roof Rejuvenation a coating?

keyboard_arrow_down

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.

Does roof rejuvenation actually work?

keyboard_arrow_down

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).

How long does the treatment last / what is the warranty?

keyboard_arrow_down

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.

What does "non-prorated" mean for my warranty?

keyboard_arrow_down

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.

How much does Structural Roof Rejuvenation cost versus a new roof?

keyboard_arrow_down

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.

Will it help against hail and wind?

keyboard_arrow_down

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.

Is my roof a good candidate?

keyboard_arrow_down

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.

How do I get it done?

keyboard_arrow_down

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.
