ROOFING CODE

Section 1504.5   

EDGE SECUREMENT FOR LOW-SLOPE ROOFS

Low-slope membrane roof system metal edge securement, except gutters, shall be designed and installed for wind loads in accordance with Chapter 16 and tested for resistance in accordance with ANSI/SPRI ES-1, except the basic wind speed shall be determined from Figure 1609.

 

CODE INTERPRETATION

The intent of the code is to ensure that the design and installation of roof edge metals and copings meet specific criteria including material specifications, wind resistance of the edge metal and the structural integrity of the substrate that anchors the edge metal, i.e. nailers, etc. The key elements considered in determining the loads on the roof edge are:

  • Wind Speed
  • Occupancy
  • Building Height
  • Location of the edge material
  • Building Location

 

ES-1 TEST METHODS

There are three test methods required under ANSI/SPRI ES-1. They are:

  • RE-1: Roof Edge Termination Test
  • RE-2: Pull-off Test for Metal Edge Flashing
  • RE-3: Pull-off Test for Metal Wall Coping
