Three tests make up the ES-1 testing process.  For complete information on the testing process, please review our metal roofing edge testing procedures below.  For additional, information on testing and building code compliance, please contact NESTS, Inc. at 404-234-3905, or use or Request Information / Quote form.  NESTS, Inc. will gladly assist you with any questions or problems associated with either local or International Building Code.

Test 1 (RE-1):  This tests the roof edge termination for mechanically attached and ballasted roofing systems.   The test evaluates the perimeter attachment to ensure that it meets a minimum holding power of 100 lbs/ft.  The membrane is pulled at a 45° angle to the roof deck to simulate a billowing membrane.  Failure is defined as any event that allows the membrane to come free of the edge termination or the termination to come free.

Test 2 (RE-2):  This is a pull-off test for metal edge flashing.  It evaluates the strength of the metal edge flashing to ensure that the fascia system meets or exceeds the building's calculated design wind pressure.  A load is applied to the fascia metal, simulating wind load on the fascia.  The calculation used is: Force at Failure X Faced Area = Blow-Off Resistance.  The results must meet or exceed the calculated design wind pressure of the building.

Test 3 (RE-3):   This test is a pull-off test for metal wall coping.   It evaluates the strength of the metal coping cap to ensure that it meets or exceeds the building's calculated design wind pressure.  A load is applied to the coping cap, simulating wind load.  Simultaneous up and out forces are used.   The calculation used is: Force at Failure X Face Area = Blow-Off Resistance.  The results must meet or exceed the calculated design wind pressure of the building.
