Appendix 6-1. SPRI Test Method RE-1
Test for Roof Edge Termination of Single-Ply
and Modified Bitumen Roofing Materials.
The method with which the edge of the roof membrane is terminated (gravel stop, nailer, or other) is
the last anchor point to hold the membrane in place should the membrane happen to separate from
the roof deck during a high wind. When this happens, the roof system will put a load on the
termination. For this reason, the termination must withstand a minimum force of 1.46 kN/m (100
lbs/ft.) when testing using the following method.
A 305 mm (12 in.) wide mock-up of the termination system should be constructed and mounted on the
base of a tensile testing device so the membrane is pulled at a 45 degree angle to the roof deck to
simulate a billowing membrane.
The roof edge termination strength is satisfactory if the test force at failure on a 305 mm (12 in.) wide
sample exceeds 445N (100 lbf).
