Powerful equipment was used to depressurize the roof sample surfaces and increase pressures from beneath.
The uplift pressure test was discontinued at 300 psf after the 2”x”10 structural framing of the sample roof section began to tear itself apart. Even at these high pressures there was no evidence of damage to the Island Style Roof system.
The uplift test pressures can be calculated to wind speeds of 342 MPH but the Florida standard TAS-125 reduces the results to 240 MPH to allow for a significant safety margin. For reference, a Category 5 hurricane has sustained wind speeds greater than 155 MPH. The Island Style Roof is designed to withstand storms of far greater winds than a Cat 5 can deliver.
