Complying with ANSI/SPRI ES-1

NRCA has released a new publication, NRCA Guidelines for Complying With Building Codes Using ANSI/SPRI ES-1, which will help designers properly design and specify perimeter edge-metal flashings to comply with building code requirements and ANSI/SPRI ES-1, "Wind Design Standard for Edge Systems Used with Low Slope Roofing Systems." The new guidelines include important information designers of low-slope membrane roof systems should know.

NRCA's guidelines

NRCA's ES-1 guide is composed of eight chapters and four appendices.

Chapter 1 provides an overview of the document's content and an introduction to wind forces acting on buildings' roofs.
