High Velocity Hurricane Zone (HVHZ)
For certain coastal areas, especially in south Florida, hurricane force winds can be more extreme than other parts of the Florida coastline and inland areas. Our product line up includes many Florida Product Approvals for various installation methods including many HVHZ approvals. If your roofing project falls in a high wind area, you may need to explore use of High Velocity Hurricane Zone (HVHZ) Florida Product approvals. The wind pressure required or “design pressure” (DP) is higher and the anchoring method is a little more stringent. Explore all of our Florida Product Approvals here including those specified as HVHZ.
All metal roofing panels installed in Florida must have Florida Product Approvals. The approval required will depend on which area or zone you are in and each approval can be researched online through the Florida Department of Business and Professional Regulation’s Building code information website https://floridabuilding.org/
Florida Product Approval
By Florida state law, building envelope components such as roofing, shutters, doors and windows are required to have a Florida Product Approval that provides evidence that the product is suitable for use in the state of Florida based on standards set in the current Florida Building Codes. Specific limitations of use are provided that limits the approved product’s use to rated structural loads.
Local Building Departments
Florida law allows for the option of either a statewide product approval or local product approval for use in the HVHZ. Products designated as approved by the Florida Department of Community Affairs (FDCA) on the department’s Building Code Information System (http://www.floridabuilding.org) must be accepted as meeting the Florida Building Code within their specified limitation of use and such products are available for use immediately upon approval. Should you have any questions, please contact the Florida Department of Community Affairs at 850-487-1824.
