By Evelyn Witterholt. 

These four metal perimeter edge products are a game changer when it comes to single-ply membrane roofing. 

How a roof looks and performs is all in the details. Single-ply roofs require quality detail products, such as perimeter edges, to help protect them against leaks and other types of damage. EXCEPTIONAL® Metals designs their edge details with this in mind, offering a variety of solutions that improve installation efficiencies and the long-term performance of roofing systems.  

Here’s four perimeter edge products from EXCEPTIONAL Metals you must know about for your next single-ply roofing job: 

1 - AllTerm® Perimeter Edge 

EXCEPTIONAL Metals’ AllTerm Perimeter Edge is considered their most versatile edge detail product . Featuring a base and snap-on metal cover as well as a factory-applied mastic, this edge detail provides an easier installation process. It’s available in 10-foot lengths and 4- to 13-inch widths and offers over several options, ensuring the right look for any building aesthetic. 

2 - 2-Piece Snap-On Compression 

The 2-Piece Snap-On Compression edge detail is the most popular edge detail EXCEPTIONAL Metals has to offer. It can be used as perimeter flashing for single-ply roofs and has a similar look as metal coping. The snap-on cover has a double-hem for extra protection and there’s no need for perimeter welding while installing. There is also no need for caulks or sealants when installing this edge detail. This detail is also largely popular because it is quick to install. 

3 - Metal Roof Edge Extender 

For roofs with wide perimeter designs, EXCEPTIONAL Metals offers a Metal Roof Edge Extender to be used alongside other edge details like gutters or coping. It’s available in a variety of metal finishes and is equipped with a continuous cleat for installation on 4-inch or wider widths.   

4 - T-Edge 

 T-Edge is a three-component edge system with a drip edge, hook strip and splice plate. These components are hooked together, allowing for easy welding to the roof’s deck as well as a visually appealing look. This edge detail can be custom-fabricated and modified depending on the pitch of the roof and it does not require an overlapping allowance.
