Professional Roofing

The most notable change between the 2014 and 2018 volumes is the elimination of the 2014 volume’s Reroofing Section. Beginning with The NRCA Roofing Manual: Membrane Roof Systems—2015 and continuing with The NRCA Roofing Manual: Metal Panel and SPF Roof Systems—2016 and The NRCA Roofing Manual: Steep-slope Roof Systems—2017, roof system-specific reroofing guidelines are provided within each volume of the manual. For example, reroofing guidelines, including roof system removal and replacement and recover criteria applicable to membrane roof systems, is provided in Chapter 9-Reroofing of The NRCA Roofing Manual: Membrane Roof Systems—2015.
