In 2001, a reroofing section was added to The NRCA Roofing and Waterproofing Manual, Fifth Edition. At that time, no other roofing industry organization publication to our knowledge offered definitive guidelines about reroofing. The section was long-awaited considering historically NRCA's annual market surveys indicate reroofing work accounts for about 60 percent of low- and steep-slope roofing sales.
The reroofing section contains information about low- and steep-slope roofing; however, this article will focus on portions related to the steep-slope text.
Steep-slope roof systems can be found on all kinds of structures, including educational facilities, places of worship, multifamily dwellings and commercial properties, as well as single-family homes.
