Steep-slope update

In January, NRCA published The NRCA Roofing Manual: Steep-slope Roof Systems—2017. This new volume updates NRCA's best practice guidelines applicable to steep-slope roof assemblies and replaces the previous edition, which was published in 2013.

2017 volume

The 2017 volume consists of 707 pages (the 2013 volume has 575 pages) and is divided into five primary sections addressing asphalt shingle, clay and concrete tile, metal shingle, slate, and wood shake and shingle roof systems.

Each section is further divided into the following chapters: Chapter 1—Roof System Configurations; Chapter 2—Roof Decks; Chapter 3—Underlayments; Chapter 4, which addresses the primary roof covering type for that section; Chapter 5—Reroofing; and Chapter 6—Construction Details.
