Metal Roofing Retrofit

The NAR NuRoof® Retrofit Roof System is a light gauge framing system fully engineered to create a slope roof plane and ready to accept a new NAR metal roofing system. You can choose either a low-slope functional and economical system where the roof is barely visible from the curbside. Or, you can choose a high-slope system with a painted standing seam metal roof system that adds to the aesthetics of the building.

This retrofit concept has been embraced by Public School Systems, and Municipal and State government agencies. NAR is nationally recognized for expert solutions supported by professional engineering analysis and proven performance products.
