Two NOAs, one rated roof: specifying Polyglass self-adhered low-slope systems in the High-Velocity Hurricane Zone

Polyglass Elastobase V, Elastoflex SA V FR, and Polyflex SA P FR are approved for the HVHZ under two different Miami-Dade Notices of Acceptance — and knowing which one carries the wind rating is the difference between a permit that sails through and a correction letter. This page explains how the approvals work, shows the assembly layer by layer, and lets you estimate your roof's required uplift pressures.
