  Product information

Product name

GRANITE-RIDGE Shingle

Product description

The panels are formed from 0.42-mm-thick aluminum zinc alloy steel sheet metal. The underside of the panels is finished with a corrosion-resistant coating. The upper surface of the panels is finished with an acrylic resin base coat onto which crushed natural stone chips are spread and then covered with an acrylic overglaze (see Figure 1). The panels are interlocked at both horizontal and vertical joints when installed.

Manufacturing plants

This evaluation is valid only for products produced at the following plants:

  • Oceanside, California, United States

  Conditions and limitations

The CCMC’s compliance opinion is bound by this product being used in accordance with the conditions and limitations set out below.

  • The panels must be installed on roofs having a minimum slope of 1 in 3.
  • The panels must be installed over solid sheathing complying with the requirements of Subsection 9.23.16., Roof Sheathing, of Division B of the NBC 2015.
  • Flashing must be installed in compliance with the requirements of Subsection 9.26.4., Flashing at Intersections, of Division B of the NBC 2015.
  • The panels must be installed with eave protection as indicated in Subsection 9.26.5., Eave Protection for Shingles and Shakes, of Division B of the NBC 2015.
  • The panels must be installed with an underlay consisting of two layers of Type 15 organic felt or one layer of Type 30 organic felt complying with the requirements of Subsection 9.26.6., Underlay beneath Shingles, of Division B of the NBC 2015.
  • Only fasteners and accessories supplied by the manufacturer may be used in conjunction with the products. The fasteners and accessories must be compatible with the base metal of the panels.
  • The panels must be installed in strict conformance with the manufacturer’s instructions.
  • The roofing systems are for use in locations where access is limited for maintenance or repair purposes. When access is needed, temporary walkways or roof boards are recommended to avoid any permanent damage to the panels.
  • The product or its packaging must be clearly identified with the phrase “CCMC 14113-R.”

Administrative information

Disclaimer

This evaluation is issued by the Canadian Construction Materials Centre (CCMC), a part of the Construction Research Centre at the National Research Council of Canada (NRC). The evaluation must be read in the context of the entire CCMC Registry of Product Assessments and the legislated applicable building code in effect.

The CCMC was established in 1988 on behalf of the applicable regulator (i.e., the provinces and territories) to ensure—through assessment—conformity of alternative and acceptable solutions to regional building codes as determined by the local authority having jurisdiction (AHJ) as part of the issuance of a building permit.

It is the responsibility of the local AHJs, design professionals, and specifiers to confirm that the evaluation is current and has not been withdrawn or superseded by a later issue. Please refer to the website or contact:
