Metal roof & single ply restoration systems
Kohls Foam Systems, Inc. offers professional restoration services for aging metal and single ply roofing systems. If your EPDM, TPO, or PVC roof is starting to show signs of wear but remains structurally sound, restoration may be the smartest and most cost-effective path forward.
We provide expert foam and coating systems designed to extend the life of your existing roof, improve waterproofing, and enhance energy efficiency—without the high cost and disruption of a full tear-off.
What Is Single Ply Roof Restoration?
Single ply roof restoration is the process of repairing and reinforcing an existing membrane roof using spray polyurethane foam and/or liquid-applied coatings. This system reinforces the current roof, seals leaks, restores insulation performance, and protects the surface from future UV damage and weathering.

Instead of tearing off and replacing the roof, restoration preserves the current membrane and upgrades its performance with a seamless, durable layer of protection.
Benefits of Roof Restoration vs. Replacement
Choosing to restore rather than replace your single ply roof can offer substantial benefits:
Cost savings: Restoration costs significantly less than a full roof replacement
Less disruption: No need to remove the existing membrane or close off building sections
Extended roof life: Adds 10–20 years of reliable performance
Energy efficiency: Reflective coatings reduce heat gain and improve insulation
Leak protection: Foam and coatings create a seamless, water-tight barrier
Seamless, Durable Application
We apply spray foam and/or elastomeric coatings directly over cleaned and prepped roofing surfaces. These materials fill cracks, seal seams, and create a fully adhered membrane with no fasteners or seams. The result is a monolithic surface that resists ponding water, hail, UV degradation, and thermal movement.

Our systems can be applied to roofs with irregular shapes, rooftop equipment, or flashing details, adapting to your structure’s unique features.
Expert Application, Proven Performance
Kohls Foam Systems has decades of experience restoring commercial roofing systems throughout Minnesota and our other licensed states. Our team uses only certified materials and follows industry best practices for preparation, application, and inspection.
We’ve restored single ply roofs on commercial facilities, manufacturing plants, municipal buildings, churches, and more. No matter the project size, we focus on precision and long-term protection.
Extend the Life of Your Roof with Metal Roofing
Metal roofing is one of the most durable and long-lasting options available, but even the strongest roofs can show signs of wear over time. At Kohls Foam Systems, Inc., we provide expert metal roof restoration and repair services that extend the life of your roof, improve performance, and prevent costly structural damage.
Based in Norwood-Young America, MN and serving five states, we offer solutions for commercial, industrial, and institutional metal roofs that need reinforcement, leak protection, or full restoration.
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:
- Inspection and documentation of problem areas
- Tightening or replacing loose fasteners
- Cleaning and prepping the entire roof surface
- Repairing seams, flashing, and damaged panels
- Application of spray polyurethane foam or acrylic/urethane coatings
- 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.
