Membrane Roof Covering and 2001 Florida Building Code - InspectionNews

I can not find any specific information which relates Membrane roof coverings to high wind velocity standards.
2001 Florida Building Code requires " shingles" sustain 2 hours at 110 mph or 140 with 3 min(or second) gusts in High wind areas.

This is actually a personal question - we're thinking of re-roofing with 100% membrane - but want to be sure it meets the 2001 Florida Building code so we retain our discount.

Any thoughts??

What slope is your roof? Sloped or flat (low slope)?

Why are you considering re-roofing with a single ply membrane unless the roof is under 2-1/2 inches in 12 inches slope?

You would need to address the roof covering through the 2007 Florida Building Code, Building (actually,the Existing Building Code, but it will kick you back to that code), and, you are not in a HVHZ (High Velocity Hurricane Zone area as only Miami-Dade and Broward counties are HVHZ, the other counties all opted not to use those higher standards.

You can get some discounts by taping the joints of the roof sheathing or installing a peel and stick underlayment which seals the roof as a secondary barrier.
