The State of Florida allows for pre-approval of products commonly used for construction within the State. Since there are countless combinations of new and existing panels and purlin spacings when it comes to retrofitting old buildings, it is impossible to pre-approve all of them.

Retro-fit roof assemblies different than those with Florida Product Approval can easily be accomplished but they will require specific project engineering to determine the proper loads, sub-framing system and correct panel needed for code compliance.

Several common retro-fit assemblies have been submitted and approved by the State of Florida. Those approvals have been listed below, however should there be any question as to the appropriate use of the below listed approvals please feel free to contact Roof Hugger, Inc. If specific project engineering is needed, contact Roof Hugger, Inc. 800-771-1711 or Force Engineering and Testing, Inc., 281-540-6603 Mr. Terry Wolfe for the cost of these services.
