If you live in Lapeer County and your asphalt-shingle roof is showing its age, you may be wondering whether you need a complete roof replacement: or whether your existing roof could qualify for rejuvenation.
The answer depends on the roof’s actual condition, not just its age or appearance.
A professional roof assessment in Lapeer County helps determine whether your shingles are still structurally sound enough for GoNano Structural Roof Rejuvenation. The process is designed to give you a clear answer before any treatment is recommended.
At Michigan Nano Roofing, the roof must qualify before we treat it. We do not apply rejuvenation treatment to failed roofs, roofs with unresolved active leaks, or roofs that require major repairs.
What Does It Mean for a Roof to Qualify?
A roof may be a candidate for rejuvenation when the asphalt shingles are aging but still intact and structurally sound.
That can include roofs showing signs such as:
- Fading or weathering
- Reduced flexibility
- Moderate granule loss
- Early brittleness
- General exposure to Michigan weather
- Normal aging without widespread failure
The purpose of an assessment is to determine whether the roof still has enough integrity for the treatment to be worthwhile.
Roof age is one consideration, but it is not the only factor. Two roofs of the same age can be in very different condition because of differences in installation, ventilation, sun exposure, storm history, roof pitch and maintenance.
A roof that is several years old may not qualify if it has serious damage. A roof that looks weathered may still be a candidate if the shingles remain sound.
What Happens During a Roof Assessment?
A roof qualification assessment is a practical evaluation of the existing roof. The goal is to understand its condition and determine whether rejuvenation is appropriate.
Here is what homeowners can generally expect.
1. We discuss the roof’s history
The assessment begins with basic information about the property and roof, including:
- Approximate roof age
- Whether the roof has had previous repairs
- Any known leaks
- Recent hail, wind or storm damage
- Whether the roof has been replaced or covered before
- Any concerns noticed from inside the home
If you know when the roof was installed, that information can be helpful. If you do not know the exact age, visible condition and inspection findings become even more important.
2. We evaluate the shingle condition
The shingles are examined for signs of aging and deterioration. This includes looking at the overall condition of the roof surface and checking whether the shingles remain reasonably intact.
The evaluation may consider:
- Cracked or broken shingles
- Curling or lifting edges
- Missing shingles
- Excessive brittleness
- Areas with heavy granule loss
- Exposed asphalt or underlayment
- Damaged ridge caps, valleys or roof transitions
- Previous patches or repairs
Granule retention matters because the granules help protect the asphalt shingles from weather exposure. Some granule loss can occur as a roof ages, but widespread bare areas or severe deterioration may indicate that the roof is no longer a good candidate.
The question is not simply, “Does the roof look old?” The more important question is, “Are the existing shingles still sound enough to benefit from treatment?”
3. We look for leaks and visible damage
A rejuvenation treatment is not intended to repair an active leak.
During the assessment, we look for signs that water may already be entering the roofing system. That may include visible roof damage, staining or other indicators of water intrusion.
Homeowners should mention any signs they have noticed, such as:
- Water stains on ceilings or walls
- Damp areas in the attic
- Dripping during rain
- Missing shingles after a storm
- Water around chimneys, vents or skylights
- Repeated interior staining
If a roof has an active leak or significant unresolved damage, that issue needs to be addressed through the appropriate roofing process. Michigan Nano Roofing does not repair active leaks, replace shingles or perform conventional roofing repairs.
This is an important distinction: GoNano Structural Roof Rejuvenation is a preservation treatment for qualified existing asphalt shingles. It is not a substitute for necessary repairs or a full replacement when a roof has failed.
4. We consider structural soundness
The roof must be structurally sound enough for treatment.
The assessment looks for concerns such as:
- Sagging areas
- Soft or unstable sections
- Extensive deterioration
- Serious water damage
- Problems that may affect worker safety
- Conditions suggesting the roof deck or underlying structure has failed
A roof can have weathered shingles and still be structurally sound. However, if the roof has major structural problems, rejuvenation is not the correct solution.
If the roof does not qualify, we will say so. A clear “not a candidate” assessment is better than applying a treatment that is unlikely to provide meaningful value.
What Happens After the Assessment?
Once the evaluation is complete, the findings are explained to the homeowner.
The possible outcomes generally include:
The roof qualifies for rejuvenation
If the shingles are aging but remain structurally sound, the roof may be eligible for GoNano Structural Roof Rejuvenation.
The treatment is designed to work at the material level of the asphalt shingle rather than simply forming a conventional layer on top. GoNano describes this process as Structural Roof Rejuvenation.
GoNano materials reference a CNETE study reporting approximately 10 to 15 years of added lifespan for qualified roofs from 0 to 12 years old. Results depend on the roof, the product system and the specific application. No treatment can make every roof a candidate, which is why qualification comes first.
The roof does not qualify
A roof may not qualify if it has failed shingles, major damage, active leaks, extensive deterioration or structural concerns.
In that situation, rejuvenation should not be presented as a solution. The appropriate next step may involve repairs or replacement through a qualified roofing contractor.
Michigan Nano Roofing does not perform those conventional roofing services. Our role is focused on applying GoNano treatment to qualified existing asphalt-shingle roofs.
More information is needed
Sometimes additional information may be needed before a final decision can be made. For example, the roof’s age may be uncertain, or certain areas may require closer evaluation.
The purpose is to avoid making assumptions. A roof qualification should be based on its actual condition.

Why an Assessment Matters in Lapeer County
Lapeer County homes experience the changing conditions common in the area. Roofs must handle summer heat, winter cold, freeze-thaw cycles, wind, rain, snow and occasional hail.
Those conditions can gradually affect asphalt shingles. A roof may still look acceptable from the ground while its flexibility and weather resistance have declined. On the other hand, visible aging does not automatically mean that replacement is required.
This is why homeowners in Lapeer, Imlay City, Almont, Metamora, Dryden, North Branch and surrounding communities should avoid making a decision based only on roof age or a quick visual glance.
A local assessment can help you understand whether your roof is:
- A potential rejuvenation candidate
- In need of conventional repair
- Too deteriorated for treatment
- Better suited for replacement planning

How Much Could Roof Rejuvenation Save?
When a roof qualifies, rejuvenation may provide a less expensive alternative to premature replacement.
GoNano treatment may cost up to approximately 80–85% less than replacing a roof, depending on the project and circumstances. That is a potential savings opportunity: not a guarantee for every home.
The final cost depends on factors such as roof size, roof condition, product system and application requirements.
The treatment can often be completed in approximately 90 minutes on average, although the actual time varies by roof. That is significantly less disruptive than removing and replacing an entire roofing system.

Common Questions About Roof Qualification
Does my roof qualify if it is old?
Possibly, but age alone does not determine eligibility. The condition of the shingles, the amount of deterioration, the presence of leaks and the structural soundness of the roof all matter.
Does my roof qualify if it has some granule loss?
Some granule loss may be consistent with normal aging. However, widespread or severe loss can indicate that the shingles are too deteriorated. An assessment is needed to determine the difference.
Can GoNano fix an active leak?
No. GoNano Structural Roof Rejuvenation is not intended to repair active leaks or failed roofs. Any necessary roofing repairs must be handled before considering treatment.
What should I search for if I need an inspection?
If you are searching online for a roof inspection near me, look for a company that will explain the roof’s condition clearly and distinguish between rejuvenation, repair and replacement. Ask whether the company evaluates qualification before recommending treatment.
What if my roof does not qualify?
A trustworthy provider should tell you. If a roof requires major repairs or replacement, rejuvenation is not the appropriate recommendation.

Find Out Whether Your Roof Qualifies
You do not have to assume that an aging asphalt-shingle roof automatically requires replacement. You also should not assume that every roof can be rejuvenated.
The best next step is a professional qualification assessment.
Michigan Nano Roofing helps homeowners evaluate their property and the area with GoNano Structural Roof Rejuvenation for qualified asphalt-shingle roofs. We assess the existing roof first, explain what we find and only recommend treatment when the roof is an appropriate candidate.
