Code compliance opinion

It is the opinion of the Canadian Construction Materials Centre that the evaluated products, when used as a metal roofing system in accordance with the conditions and limitations stated in this evaluation, comply with the following code:

National Building Code of Canada 2015

Code provision Solution type
9.26.1.2.(1) Roofs shall be protected with roofing, i ...Acceptable
9.26.13.1. ThicknessAcceptable
9.26.2. Roofing MaterialsAlternative
9.3.3.2. Galvanized Sheet SteelAcceptable

The above opinion is based on the evaluation by the CCMC of technical evidence provided by the evaluation holder, and is bound by the stated conditions and limitations. For the benefit of the user, a summary of the technical information that forms the basis of this evaluation has been included.

  Product information

Product names

  • ArrowLine Shingle Shake
  • ArrowLine Slate

Product description

The panels are manufactured from 0.37-mm-thick galvanized steel coated with polyvinylidene fluoride (PVDF). The underside of the panels is finished with a corrosion-resistant coating. The panels are 1 288 mm × 325 mm, of which 1 270 mm × 305 mm is exposed. The panels are stamped to simulate traditional shake or slate roofing products.

The panels have an interlocking system on all four sides and are installed from left to right using five fastener clips per panel. The complete roofing system includes accessories such as an eave and rake starter, ridge and hip cap, shingle and valley clips, valley flashing and cap, and end wall flashing.

 

Manufacturing plants

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

  • Hopkins, Minnesota, 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.
  • An underlay consisting of two layers of Type 15 organic felt or one layer of Type 30 organic felt must be used in conjunction with the panels.
  • 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.
  • Flashing must be installed in compliance with the requirements of Subsection 9.26.4., Flashing at Intersections, 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 roofing system is for use in locations where access is limited to maintenance or repair purposes. When access is needed, temporary walkways or roof boards are recommended to avoid any permanent damage to the panels.
  • The roofing system must be installed by manufacturer-approved installers in strict conformance to the manufacturer’s instructions.
  • The product must be clearly identified with the phrase “CCMC 13380-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:
