2 Revision History

This Standard was revised effective February 1, 2024 and replaces the Standard dated October 20, 2023.


3 History of the Roofing Practices Manual

The RGC Roofing Practices Manual ("RPM", or "Manual") is the official collection of

  • published Standards necessary to design and build a waterproofing or water-shedding project intended to qualify for a RoofStar Guarantee.
  • listed materials formally accepted by the RCABC Guarantee Corporation (RGC), with which a project must be constructed to qualify for a RoofStar Guarantee.
  • information, technical standards and other resources intended to aid the Design Authority in specifying such a project.

The RPM was first produced in 1988 by the RCABC Guarantee Corporation (RGC) Technical Committee, under the direction of the RGC Board of Directors. Its initial development was supported by representatives of the

Architectural Institute of British Columbia (AIBC)
Intergovernmental Roofing Advisory Group (IRAG)
National Research Council (NRC)
Roofing Inspectors and Consultants Association of British Columbia (RICABC)

Development of the RPM received its major impetus when the National Research Council, represented by its Industrial Research Assistance Program, provided financial assistance to the RCABC, so that a British Columbia Institute of Technology graduate could be hired to assist in the compilation of the very first Manual. Various extracts of information were authorized for reference by the

Canadian Roofing Contractors Association (CRCA)
National Roofing Contractors Association (NRCA)

and further valuable guidance was made available to the RCABC by the

Alberta Roofing Contractors Association (ARCA)
Roofing Industry Educational Institute (RIEI)

The completion of the 1988 Edition of the RPM initiated the development and subsequent expansion of the RCABC Guarantee for Workmanship and Materials, now called the RoofStar Guarantee Program. The RGC Roofing Practices Manual is an evolving document that is supported by RCABC Members, RGC Accepted Observers, the NRC, the British Columbia design community and other construction associations. It is revised and updated no fewer than three (3) times annually. Revisions to the RPM are published online (Technical Updates) and have been digitally updated since November 2010. Previous Technical Updates may be available from the Technical Department of the RCABC, upon written request.


4 Structure of the Roofing Practices Manual

The structure of the RPM has changed over time. Originally published as a paper-based binder with twelve tabs, it was digitized in 2012 and converted to an online wiki format. In 2016, the wiki-based RPM was restructured to form eight Divisions, A through H.

Division A: Purpose, Scope and Guarantee
Division A contains important information about the RPM and the RoofStar Guarantee Program, including any limitations and exclusions applicable to a RoofStar Guarantee.
Division B: Standards
Standards are listed by system according to the weather-side surface, and are further divided by system categories - Roof Waterproofing Systems, Water-shedding Systems, and Grade-level Waterproofing Systems. Explanatory notes may be incorporated at the end of each Standard.
Division C: Accepted Materials
Division C contains all the listed Accepted Materials used in the RoofStar Guarantee Program; it is searchable by a variety of methods, each made simple by ready hyperlinks.
Division D: Construction Details
Division D houses the construction details that support each Standard. Construction Details are categorized by Division and then by System, and each System is then organized by the Part structure with which each Standard is organized.
Division E: General Information

Each Standard is prepared by the RCABC Guarantee Corp. (RGC) Technical Committee, under the final approval of the RCABC Guarantee Corp. (RGC) Board of Directors and is republished every four months. While printable versions of each Standard are available for download by users of the RPM, the online version remains the authoritative document in all respects.
