Metal Roof Restoration and Repair

Do You Need Metal Roof Repairs?

It’s easy to overlook early signs of deterioration in metal roofs, but small issues can lead to larger problems if not addressed. Common signs that your metal roof may need professional repair include:

Punctures or tears

Often caused by foot traffic or improper equipment handling, holes and tears must be sealed promptly to prevent water damage.

Rust or corrosion

Although most metal roofs are treated to resist rust, exposure and age can break down protective layers. If corrosion has begun, the affected areas need cleaning and re-sealing.

Sealant failure

Sealants used at seams and fasteners typically last 15 to 20 years. When they begin to crack or deteriorate, leaks and separation are likely to follow.

Loose seams or fasteners

As temperatures fluctuate, metal roofing expands and contracts. Over time, this movement loosens seams and fasteners, allowing water intrusion and wind uplift.

Our Restoration Process

protects, and insulates. Our systems combine cleaning, priming, and the application of spray foam or elastomeric coatings to create a seamless surface.

Our approach includes:

1. Inspection and documentation of problem areas
2. Tightening or replacing loose fasteners
3. Cleaning and prepping the entire roof surface
4. Repairing seams, flashing, and damaged panels
5. Application of spray polyurethane foam or acrylic/urethane coatings
6. Final reflective topcoat for UV protection and thermal performance



This process is ideal for roofs that are structurally sound but experiencing leaks or surface deterioration.

Why Restore Instead of Replace?

Roof restoration is often the most practical and cost-effective choice for aging metal roofs. Benefits include:

• Extended roof lifespan by 10 to 20 years
• No need to remove the existing roof
• Seamless, water-resistant barrier
• Energy savings from improved insulation and reflectivity
• Reduced long-term maintenance
• Less disruption to building occupants and operations



Our systems also qualify for many energy rebates and tax incentives due to their high reflectivity and insulating properties.

Projects and Performance

We’ve restored metal roofs on a wide range of buildings including churches, agricultural facilities, and commercial complexes. Our foam and coating systems perform in all climates, from the snow loads of Minnesota to the humidity of Hawaii.

For example, when St. Andrew Lutheran Church needed their camp chapel insulated and protected, they turned to Kohls Foam Systems. After installation, the chapel became the most temperature-stable building on the property—cool in the summer and warm in the winter.
