NRCA roofing manuals links
The goal of NRCA's roofing manuals has always been to provide best industry practices
and technical information concerning the design, materials and installation of roof
systems. They present time-tested, best-practice guidelines for roofing buildings
and other enclosed structures that have been collected by NRCA from knowledgeable,
practicing roofing contractors located throughout the U.S.
NRCA made the decision to substantially reformat the manual in 2007 while updating
and expanding its technical content. With previous editions, all sections of the
manual were published concurrently. The NRCA Roofing Manual will be published as
a four-part series, with one part of the series of the manual being published each
year over a four-year period.
The NRCA Roofing Manual is intended to update and supersede
The NRCA Roofing and
Waterproofing Manual, Fifth Edition, including its 2003 and 2006 interim
updates. The NRCA Roofing Manual is a four-volume series that includes
The NRCA Roofing
Manual: Steep-slope Roof Systems—2013,
The NRCA Roofing Manual: Metal Panel
and SPF Roof Systems—2012,
The NRCA Roofing Manual: Membrane Roof Systems—2011
and
The NRCA Roofing Manual: Architectural Metal Flashing, Moisture Control and Reroofing—2010.
This makes the NRCA Roofing Manual NRCA's premier technical reference set.
In 2001,
The NRCA Roofing and Waterproofing Manual, Fifth Edition, was published
and consisted of 1,474 pages in a four-volume boxed set. The fifth edition updated
the previous editions and added several new sections, including a comprehensive
"Reroofing" section addressing reroofing considerations and a "General Roofing Project
Considerations (GRPC)" section. In 2003 and 2006, interim updates to the fifth edition
were published to reflect updated technology and changes in NRCA's guidelines.
In 2005, NRCA published
The NRCA Waterproofing Manual, 2005 Edition, as a
result of the decision to no longer include the waterproofing section in the NRCA
roofing manuals. Instead, the waterproofing section has been substantially updated
and issued as a separate publication to provide technical information concerning
the design and installation of quality waterproofing systems.
In 1996, the fourth edition of The NRCA Roofing and Waterproofing Manual was published
and consisted of a two-volume set containing 1,858 pages. The fourth edition represented
a significant change from previous editions because a vast majority of the text
was rewritten. Also, several new sections were added, including "The NRCA Metal
Roofing Manual," "The NRCA Sprayed Polyurethane Foam-based Roofing Manual" and "The
NRCA Energy Manual."
In 1989, the third edition of the manual was published. This edition consisted of
726 pages and contained information updated from the second edition.
An updated version of the manual's first edition was published in 1983; this updated
edition still was referred to as the first edition of the manual. Changes incorporated
into the 1983 version of the manual include revised built-up roofing (BUR),
Handbook
of Accepted Roofing Practice (HARK) and glossary sections and inclusion
of the new technical bulletins released since the first edition originally was published
in 1981. In 1985, a reformatted, updated and expanded second edition of The NRCA
Roofing and Waterproofing Manual was published. This edition consisted of 702 pages
and provided new detailed information about single-ply and polymer-modified bitumen
sheet membrane roof systems, as well as a separate section providing specifications
for low-slope membrane roof systems.
In 1981, the first edition of the manual, The NRCA Roofing and Waterproofing Manual,
was published. This edition consisted of 442 pages and contained information about
BUR membranes and steep-slope roof systems, waterproofing systems, a limited number
of construction details and reprints of NRCA's then-current technical bulletins,
and HARK. At the time the first edition was published, single-ply membrane roof
systems were just beginning to enter the U.S. roofing market and, therefore, little
information regarding single-ply roof systems was included in this edition.
NRCA published its first manual,
A Manual of Roofing Practice, in 1970. This
was NRCA's first reference guide developed by roofing contractors to address good
roofing practices. This manual subsequently was revised in 1971, 1973 and 1976.
In its original and revised editions,
A Manual of Roofing Practice primarily
addressed roofing practices relating to built-up membrane roof systems.
