Field Fastener Withdrawal Test for flat roof systems
We begin by cutting through the existing roof system to reach the roof deck. Using a Com Ten withdrawal tester, we install the fastener type specified by the proposed roof system to be used. The installed fastener is then withdrawn and the pullout resistance is measured and recorded. After completion of the withdrawal test, the cut out area is patched and sealed. This test will verify if the proposed fasteners will provide sufficient uplift resistance to the hurricane wind withdrawal forces as required by the Florida Building Code.
