Perimeter edge metal FAQs
The term 'edge metal' encompasses different types of profiles that are used at a roof's perimeter: fascia, drip edge, gravel stop metal, and copings for parapets.
In 1997, research was conducted by the Institute for Disaster Research at Texas Tech University, Lubbock, to gain a better understanding of wind loading on edge metal. This was in response to failures of perimeter edge metal flashing as a result of Hurricanes Hugo and Andrew and other major storms. In 1998, SPRI published its first edition of ANSI/SPRI ES-1, “Wind Design Guide for Edge Systems Used With Low Slope Roofing Systems.” The standard was based on data obtained from the Texas Tech University research. The standard was updated in 2003, 2011, 2017 and the most recent edition was issued in 2022. It is now titled ANSI/SPRI/FM 4435 ES-1, “Test Standard for Edge Systems Used with Low Slope Roofing Systems” (ES-1). ES-1 has been incorporated into the International Building Code (IBC) and provides an industry-recognized, consensus-based method for designing perimeter edge metal systems where the edge metal secures the roof membrane.
Yes, perimeter edge metal is required by building codes. Specifically, ANSI/SPRI/FM 4435 ES-1 and ANSI/SPRI GT-1 are referenced in Section 1504-Performance Requirements in the International Building Code (IBC). Other local codes may apply as well.
Drip Edge is metal flashing installed along the edges of a roof to direct rainwater away from the underlying wood and into the gutter.
Gravel Stop is a metal edge flashing commonly used on low-slope or flat roofs featuring a raised lip or vertical edge that contains the gravel or ballast on a built-up (BUR) roof. It also acts as a drip edge.
Fascia is a horizontal board or trim running along the perimeter of the roofline, behind the gutter, providing a finished appearance while also acting as a structural anchor for the gutter system.
Coping is the protective cover installed on the top of a free-standing wall, protecting the masonry or structural wall underneath from water infiltration.
