System Design Pressure -355 psf
Max. Calculated Uplift Pressure-171.75 psf
These calculations have been done in accordance with ASCE 7-16, based on the information provided by the
contractor. Since the system design pressure is greater than the calculated maximum uplift pressure in any zone,
the aforementioned system may be used on the subject roof. The roof system must be installed in accordance
in accordance with the Florida Building Code and the roof system manufacturer's recommendations.
Ensure that roof system meets drainage, insulation and fire rating requirements of the Florida Building Code.
