When Michigan homeowners search for a roof coating vs. replacement option, they often find several products described as coatings, sealants, restorers, or roof treatments. The terms can sound interchangeable, but they do not always describe the same technology or process.
GoNano is different.
GoNano is not a roof coating, paint, or surface sealant. It is a process called Structural Roof Rejuvenation, designed to modify and enhance qualified asphalt shingles from within the shingle structure.
That distinction matters when you are deciding whether to replace an aging roof, apply a conventional coating, or investigate a roof treatment for asphalt shingles.
What Is a Conventional Roof Coating?
A conventional roof coating is generally a material applied over the existing roof surface. Depending on the product, it may be designed to provide a protective layer, improve water shedding, reflect sunlight, or cover certain surface imperfections.
Coatings can have legitimate uses in specific roofing systems. However, a surface coating works primarily by creating a layer on top of the roofing material. It does not necessarily restore the internal properties of aging asphalt shingles.
A coating may not be appropriate for every shingle roof. The product must be compatible with the roofing material, the roof must be in suitable condition, and application requirements vary by manufacturer. A coating should not be viewed as a universal solution for missing shingles, active leaks, structural damage, or a failed roof.
This is why homeowners should ask an important question before choosing any product:
Is the product creating a surface layer, or is it designed to work within the shingle itself?
How GoNano Is Different From a Roof Coating
GoNano Structural Roof Rejuvenation uses nanosilica particles that penetrate the asphalt shingle structure and modify the asphalt at the molecular level. The treatment is designed to work within the shingle rather than simply forming a film across its surface.
In simple terms:
- A traditional coating sits primarily on top of the roof.
- GoNano is designed to work inside qualified asphalt shingles.
- A surface sealant creates a layer.
- GoNano’s Structural Roof Rejuvenation process is intended to modify and enhance the existing shingle structure.
GoNano describes its technology in more detail through its explanation of Structural Roof Rejuvenation.
The treatment is not just another name for a blended coating or a different type of penetrant. Products can vary significantly in their chemistry, application process, intended use, testing, and documentation. Homeowners should evaluate the specific product rather than assuming that every roof treatment performs the same way.
What Happens as Asphalt Shingles Age?
Asphalt shingles are exposed to changing conditions every day. In Michigan, that includes summer heat, ultraviolet exposure, rain, snow, ice, wind, and repeated freeze-thaw cycles.
Over time, an aging shingle roof may experience:
- Loss of flexibility
- Brittleness
- Weathering and fading
- Granule loss
- Thermal stress
- Deterioration of the asphalt material
An older roof is not automatically a failed roof. Some roofs may still be structurally sound even though the shingles are showing normal signs of aging.
That is the situation Structural Roof Rejuvenation is designed to address. The objective is not to rebuild the roof or conceal serious damage. The objective is to help preserve qualified shingles that may still have useful life remaining.
Roof Rejuvenation vs. Roof Coating: A Practical Comparison
| Consideration | Conventional Roof Coating | GoNano Structural Roof Rejuvenation |
|---|---|---|
| Where it works | Primarily on the roof surface | Within the asphalt-shingle structure |
| Material description | Coating, paint, or sealant depending on product | Penetrating nanosilica-based treatment |
| Main purpose | Creates a surface layer for a specific roofing application | Rejuvenates qualified aging asphalt shingles |
| Roof condition required | Varies by product | Roof must be assessed and qualify |
| Repairs failed roofing? | No | No |
| Application method | Varies by product | Professional low-pressure spray application |
| Typical application time | Varies | Approximately 90 minutes on average, depending on the roof |
| Replacement alternative | Sometimes considered as part of a roof-maintenance plan | Designed as an option for qualified roofs before premature replacement |
The comparison is not meant to suggest that every conventional coating is ineffective or that every roof is a candidate for GoNano. The right choice depends on the roof’s condition, material, age, and needs.
The key point is that GoNano should not be categorized as a surface coating.
What Testing Supports GoNano’s Technology?
GoNano states that its technology has undergone more than $1 million in testing and evaluation. Testing has included areas such as impact resistance, granule loss, tear strength, fire resistance, wind resistance, and molecular aging.
Referenced standards include:
- UL 2218 for impact resistance
- ASTM D3161 for wind resistance
- UL 790 for fire resistance
GoNano also references a CNETE study reporting an added lifespan of approximately 10 to 15 years for qualified roofs in the 0-to-12-year range, depending on the roof and testing conditions.
These findings should be understood as product and testing information: not a guarantee that every roof will receive the same result. Roof age, condition, installation history, climate exposure, and maintenance all matter.
For additional technical information, homeowners can review GoNano’s science and technology resources.
Is GoNano a Roof Replacement Alternative?
For a roof that has failed, replacement may be necessary. Structural Roof Rejuvenation is not intended to change that.
However, homeowners are sometimes advised to replace a roof based primarily on age, even when the roof may still be structurally sound. In those cases, it can make sense to explore alternatives before committing to a major replacement project.
A GoNano treatment may cost up to approximately 80–85% less than replacement, depending on the specific roof and project circumstances. That is a potential savings opportunity, not a guaranteed percentage for every homeowner.
The application can often be completed in approximately 90 minutes on average, although the actual time varies by roof size, access, and conditions. Compared with tear-off, disposal, material delivery, and a full replacement installation, the process is designed to be considerably less disruptive.

Which Roofs May Qualify?
GoNano is intended for asphalt-shingle roofs that are aging but still structurally sound. A roof may be worth evaluating if it has signs of weathering, fading, reduced flexibility, or early deterioration but does not require major repairs.
A roof may not qualify if it has:
- Active leaks
- Significant structural failure
- Major storm damage
- Missing or extensively damaged shingles
- Severe deterioration
- Problems requiring conventional roofing repairs
Michigan Nano Roofing does not repair active leaks, replace shingles, replace decking, install underlayment, repair flashing, perform ventilation work, or install replacement roofs. If the roof requires those services, it is not an appropriate candidate for our treatment.
That qualification step is central to responsible roof preservation. We are not trying to treat every roof. We are trying to identify roofs where rejuvenation may be a reasonable option.

Why the Terminology Matters
Calling GoNano a “roof coating” may seem harmless, but it can create the wrong expectations.
A homeowner may assume the product is a paint-like layer that covers the shingles. They may expect it to seal an active leak or hide serious damage. Neither assumption is correct.
GoNano is a Structural Roof Rejuvenation treatment for qualified asphalt shingles. It is applied as a low-pressure spray, but its purpose is not to leave a conventional film on the roof. The technology is designed to penetrate and modify the existing shingle structure.
That is also why a professional assessment is necessary before treatment.
Frequently Asked Questions
Is GoNano paint?
No. GoNano is not paint. It is a nanosilica-based Structural Roof Rejuvenation treatment designed to work within qualified asphalt shingles.
Is GoNano a sealant?
No. GoNano is not a conventional surface sealant. It is designed to penetrate the asphalt shingle structure rather than simply sit on top of it.
Can GoNano repair a leaking roof?
No. GoNano is not intended to repair active leaks, failed roofs, or major structural problems. Those conditions must be addressed through appropriate roofing work.
Is roof rejuvenation the same as shingle restoration?
The terms may be used broadly in the roofing industry, but GoNano specifically refers to its process as Structural Roof Rejuvenation. The treatment is designed to preserve and enhance qualified existing asphalt shingles rather than replace them.
How do I know if my roof qualifies?
The roof must be assessed. Contact Michigan Nano Roofing at 810-545-6364 or use the assessment form below.
