ENHANCED WIND UPLIFT FASTENING REQUIREMENTS

The following is general information regarding Flex TPO Plus Roof System design requirements for areas

in which wind speed velocities may occur in excess of 55 miles per hour. A wind uplift pressure design

professional accredited in the specific area should calculate the wind uplift pressure resistance required for

the project. The wind uplift pressure resistance values can then be matched to existing approved Flex

Roof Assemblies. Contact Flex Technical Services for additional information regarding approved

assemblies.
