ANSI/SPRI CERTIFICATION


The American National Stan- dards Institute (ANSI) is a non-profit organization that administers and coordinates a voluntary standardization system.

SPRI, (Single Ply Roofing Indus- try) is a non-profit trade association representing the sheet membrane and component supplier to the commercial roofing industry. SPRI is an official ANSI canvasser and has worked with representatives of the roofing industry to develop a number of consensus standards. SPRI offers a seminar on Perimeter Edge Wind Design (click for information)

The ANSI/SPRI ES-1 Standard is a reference for those who design, specify or install edge materials used with low slope roofing systems. It addresses copings and horizontal roof edges. The following factors are considered when designing a roof edge. click here to learn more about ANSI-SPRI ES-1 standard.

Structural Integrity of the Substrate (e.g. nailers)

Wind Resistance of Edge Metal

Material Specifications

Factors are used in ANSI/SPRI ES-1 to determine the loads on a roof edge

Wind Speed (Use ANSI/SPRI ES-1Calculator)

Building Occupancy

Building Height

Location of the Edge Device on Roof

Building Location

Tests Performed by Area-24 to Certify Products:

RE-1:

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. per ftt. The membrane is pulled at a 45 degree 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.

RE-2:

A pull-off test for metal edge flashing to evaluate the strength of the metal edge flashing to ensure that the fascia system meets or exceeds the buildings calcu- lated 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 face area = blow off resistance. The results must meet or exceed the calculated design wind pressure of the building.

RE-3:

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 calculations used to determine the blow-off resistance for the top, face leg and back leg are: force at failure X surface area = blow-off resistance. The results must meet or exceed the calculated design wind pressure of the building.
