A commercial metal roof in Devils Lake, ND has to handle snow, ice, strong wind, rain, and major temperature changes. That exposure can result in rust, loose fasteners, open seams, failed sealants, and leaks over time. But an aging metal roof doesn’t always have to be torn off and replaced.
Metal roof restoration is a viable solution when the existing roof is still in suitable condition. Restoration involves correcting existing problems, preparing the roof surface, and applying a compatible system to help protect the existing metal roof.
The first step is to understand the condition of the roof. A coating should not be used to cover problems that need to be repaired first.

What Does Metal Roof Restoration Involve?
Metal roof restoration is more than applying a new coating. The work begins with an inspection of the existing roof system to determine its condition and identify areas that need repair.
A contractor should inspect the metal panels, seams, fasteners, flashings, penetrations, curbs, drainage areas, and other roof details. If there are signs of moisture, those areas may need further investigation.
Depending on the condition of the roof, the repair and preparation work may include:
- Cleaning the metal surface
- Treating surface rust
- Repairing or replacing damaged panels
- Correcting loose or damaged fasteners
- Repairing flashing details
- Preparing existing coatings
The actual scope depends on what the roof inspection finds. Not every commercial metal roof needs the same work.
Is Every Metal Roof Suitable for Restoration?
No. The existing roof needs to be in suitable condition before restoration is recommended. A roof with sound panels and localized problems such as surface rust, loose fasteners, worn coatings, or failed sealants may be a good candidate. A roof with widespread structural damage or severe deterioration may require a different solution.
The substrate matters too. Commercial metal roofs have various types of panels, existing coatings, primers, sealants, and previous repairs. The restoration products need to be compatible with those existing materials.
Choosing a coating before understanding the substrate can lead to adhesion problems or poor performance. That is why an inspection should come before the restoration system is selected.
Why Are Moisture Checks Important?
Even a metal roof that looks good from above can have moisture issues below the surface. Water can enter around failed seams, fasteners, penetrations, flashings, and other weak spots. Simply coating the top of the roof will not address wet insulation or damage within the roofing assembly.
Moisture checks help identify areas that need further attention. Depending on the building and roofing assembly, a contractor may use visual inspection and other suitable moisture-detection methods. Suspected hidden moisture may require additional investigation to confirm.
If wet materials or other hidden damage are found, those conditions should be addressed before the final restoration system is installed.
What Repairs Should Be Done Before Coating?
Repairs are an important part of the restoration process. Loose or damaged fasteners need correction using methods suited to the panel and supporting structure. Open seams and failed sealants may need repair. Surface rust may need cleaning and treatment, while severe corrosion can require panel replacement. Flashing around penetrations and other transitions also needs attention where damaged.
Drainage should be taken into account. Standing water that repeatedly collects on a roof adds weight and can point to a drainage problem requiring attention.

There is no standard repair list for every building. The right repairs depend on the condition of the individual roof.
How Is a Metal Roof Prepared for Restoration?
Surface preparation is one of the most important parts of the job. Before coating, the roof needs to be clean and ready for the selected materials. Dirt, loose coating, rust, failed sealants, and other contaminants can affect adhesion.
Preparation may involve cleaning the metal, treating rust, removing failed materials, and making repairs. The roof also needs to meet the selected products’ dryness requirements when those materials are applied.
Weather conditions are especially important in North Dakota. Temperature and moisture conditions can affect application and curing, so the work should follow the requirements of the selected system.
Good preparation gives the restoration materials a suitable surface to bond to.
What Materials Are Used in a Metal Roof Restoration System?
A commercial metal roof restoration system may use several materials rather than a single product. Depending on the roof, the system may include primer, seam sealant, reinforcement materials, and a protective roof coating. Each component should be selected based on the existing substrate and the manufacturer’s requirements.
A typical process may look like this:
- Inspect the existing roof.
- Check for moisture and damaged areas.
- Complete necessary repairs.
- Clean and prepare the surface.
- Apply primer where required.
- Treat seams, fasteners, and penetrations according to the selected system.
- Apply the specified coating system.
- Inspect the completed work.
The goal is to create a properly repaired, prepared, and protected roofing surface, not simply to cover the existing metal.
Can Restoration Extend the Life of a Metal Roof?
Yes, when the existing roof is suitable and the work is properly performed. Restoration can address repairable problems such as surface rust, failed sealants, leaking seams, and loose fasteners. The restoration system can then provide additional protection against weather exposure.
Restoration, however, will not make an old roof new. Its expected performance depends on the original roof condition, repairs, surface preparation, materials, installation, drainage, weather, and future maintenance.

Is a Product Warranty the Same as Roof Service Life?
No. These are two different things. A product warranty explains what the manufacturer may cover under specific terms and conditions. It does not automatically guarantee that the entire restored roof will perform for the same number of years.
An installation or workmanship warranty, when offered, covers specified responsibilities tied to the contractor’s work. Its coverage depends on the written terms.
Expected service life is an estimate of how long the roofing system may perform when properly installed and maintained under suitable conditions.
Property owners should ask what warranties are included, what they cover, what maintenance is required, and what service life can reasonably be expected from the complete restoration system.
When Should a Commercial Metal Roof Be Restored?
The roof’s condition matters more than its age alone. If the metal panels remain generally sound and the primary problems are repairable, restoration may be a practical option. If the roof has widespread deterioration, severe corrosion, structural damage, or other conditions that cannot reasonably be addressed through restoration, replacement may be more appropriate.
A simple way to think about the decision is:
- Localized problems: Repairs may be sufficient.
- Sound roof with widespread surface deterioration: Restoration may be worth evaluating.
- Severe deterioration or structural problems: Replacement or structural repairs may be necessary.
A professional inspection can help determine the appropriate approach for the building.

FAQ About Metal Roof Restoration in Devils Lake, ND
1. How do I know if my metal roof needs restoration?
Rust, leaks, loose fasteners, open seams, failed sealants, and worn coatings can indicate that a roof needs attention. An inspection can help determine whether restoration is appropriate.
2. Can a rusty metal roof be restored?
Sometimes. Surface rust can often be cleaned and treated. Severe corrosion may require panel replacement or other substantial repairs before restoration can be considered.
3. Can metal roof restoration fix leaks?
It can address leaks caused by repairable problems around seams, fasteners, penetrations, and flashing. The source of the leak should be identified and repaired before coating.
4. Why check for moisture before restoration?
Moisture may be present below the visible roof surface. Finding wet areas first helps prevent hidden problems from being covered by the restoration system.
5. Can any coating be used on a metal roof?
No. The primer, sealant, and coating should be compatible with the existing substrate and the selected restoration system.
6. How important is surface preparation?
Very important. Dirt, rust, loose materials, and failed coatings can interfere with adhesion. Proper cleaning and preparation are necessary before application.
