Superior Strengthening Retrofit

The superior profile and manufacturing process of the TopHat Subframe Roof Retrofit Framing System is what sets it apart from competing systems such as RoofHugger. Read below to find out why.

Superior Strengthening Metal Roof Retrofit

The TopHat Subframe is the industry's most advanced retrofit framing system. Featuring superior energy efficiency, a stronger structural profile and superior compliance with newly strengthened building codes, TopHat is the unchallenged leader in retrofit metal roofing solutions. The TopHat Subframe is compatible with a variety of standing seam and exposed fastener panels to complete your new roof.

The TopHat Subframe is an economical and efficient way to replace an existing metal roof. By putting a new and improved roof right over your existing roof structure, you achieve lower labor costs and minimal business interruption. The TopHat Subframe member is attached directly to the existing purlin (or to the deflection limiter between existing purlins). Your new roof panel is then attached directly to the TopHat Subframe.

Seamless Subframes

One of the many benefits of the roll-forming process used to manufacture the TopHat Subframe is that it can be produced in arbitrary lengths. Continuous subframe sections can go bay to bay or longer without splices creating a stronger roof than older systems that require splicing. In fact, an early test of continuous TopHat Subframe was still 7% stronger than RoofHugger despite using 24% lower yield steel!

Stronger, Consistent Steel

The roll-forming process is superior when it comes to manufacturing consistency and tolerances with higher yield steels. It is generally accepted that roll forming produces an end product free from distortion due to springback. As a result, every single piece of TopHat Subframe is exactly the same, exactly as designed, and exactly what you want. In fact, roll-forming is the only way to manufacture the TopHat profile!
