1. Opinion

It is the opinion of the Canadian Construction Materials Centre (CCMC) that “Allmet Continental, Shadowline, Woodshake, Talavera SF, Talavera NB, Classic Tile, Classic Tile NB, Tudor Slate NB, Ridgewood NB”, when used as a metal roofing system in accordance with the conditions and limitations stated in Section 3 of this Report, complies with the National Building Code 2010:

  • Clause 1.2.1.1.(1)(a), Division A, using the following acceptable solutions from Division B:
    • Article 9.26.13.1. Thickness (sheet metal roofing)
  • Clause 1.2.1.1.(1)(b), Division A, as an alternative solution that achieves at least the minimum level of performance required by Division B in the areas defined by the objectives and functional statements attributed to the following applicable acceptable solutions:
    • Article 9.26.2.1. Material Standards (roofing material)

This opinion is based on CCMC's evaluation of the technical evidence in Section 4 provided by the Report Holder.

2. Description

The “Allmet Continental, Shadowline, Woodshake, Talavera SF and Classic Tile” panels are formed from 0.46-mm-thick aluminum-zinc alloy steel sheet metal.

The “Talavera NB, Tudor Slate NB, Ridgewood NB, and Classic Tile NB” panels are formed from 0.42-mm-thick aluminum zinc alloy steel sheet metal.

The underside of all the panels is finished with a corrosion-resistant coating. The upper surface of the panels is finished with an acrylic resin basecoat onto which mineral aggregates are spread and covered with an acrylic overglaze. See Figure 1.

The “Allmet Continental, Shadowline, Woodshake, Tudor Slate NB, Ridgewood NB, Talavera SF and Talavera NB” panels have 1 200 mm x 402 mm of exposed surface.  The “Classic Tile and Classic Tile NB” panels have 1 067 mm x 357 mm of exposed surface.

The panels are designed to resemble traditional tile (“Classic Tile, Classic Tile NB and Shadowline”) (see Figure 2), barrel tile (“Allmet Continental, Talavera SF, and Talavera NB”) (see Figure 3), wood shake (“Woodshake and Ridgewood NB”) (see Figure 4), and slate (“Tudor Slate NB”).

The complete roofing system includes accessories such as a foam closure strip, metal bird edge, fascia, gable, flashing wall, ridge, hip cover, valley, Z-bar, and fasteners.

The “Classic Tile, Allmet Continental, Shadowline, Woodshake, and Talavera SF” are installed with battens.  The installation starts from the ridge down to the eave. Installation of each course is from left to right lapping the side of the panels right over left and staggering the joints in adjacent courses.

The “Classic Tile NB, Talavera NB, Tudor Slate NB, and Ridgewood NB” are installed without battens.  The installation starts from the eave up to the ridge.  Installation of each course is from left to right lapping the side of the panels right over left and staggering the joints in adjacent courses.

3. Conditions and Limitations

CCMC's compliance opinion in Section 1 is bound by the “Allmet Continental, Shadowline, Woodshake, Talavera SF, Talavera NB, Classic Tile, Classic Tile NB, Tudor Slate NB, Ridgewood NB” 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 2010.
  • 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.
  • Flashing must be installed in compliance with the requirements of Subsection 9.26.4., Flashing at Intersections, of Division B of the NBC 2010.
  • 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 2010.
  • 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 systems must be installed by manufacturer-approved installers in strict conformance to the manufacturer's instructions.
  • The roofing systems are for use in locations where access to the roof is limited to maintenance or repair purposes. Foot traffic should be limited over battens, for panels fastened to battens, and over endlap, for panels fastened directly to roof deck. When access is needed, temporary walkways or roof boards are recommended to avoid any permanent damage to the panels.
  • The use of the panels is limited to geographical areas where the wind load, as factored for local exposure conditions and building heights, does not exceed 170 km/h.

4. Technical Evidence

The Report Holder has submitted technical documentation for CCMC’s evaluation. Testing was conducted at laboratories recognized by CCMC. The corresponding technical evidence for this product is summarized below.

4.1 Performance Requirements

4.1.1  Base Material

The panels meet the requirements for aluminum-zinc alloy material in accordance with ASTM A 792/A 792M-06A, “Steel Sheet, 55% Aluminum-Zinc Alloy-Coated by the Hot-Dip Process,” and the coating designation Z150.

4.1.2  Traffic Load Test

Sidelap Visible permanent deformation
Endlap No visible deformation
Note to Table 4.1.2:
Footnote 1

Permanent deformations were observed during the test for both panels.  See Section 3, Conditions and Limitations of this Report for limitations regarding foot traffic on the panels.

4.1.3  Uniform Load Test

“Allmet Continental” panels were loaded in increments up to 6 kPa without failure and with no permanent deformations.  The panels were then loaded until failure.  At 9.4 kPa the panels buckled at the ridges.

4.1.4  Wind Uplift

“Allmet Continental and Talavera NB” panels were tested in accordance with UL 580, “Uplift Resistance of Roof Assemblies,” up to a maximum load of 5.03 kPa.  The panels were then tested starting from 3.04 kPa, increasing the pressure in increments of 0.72 kPa and holding for 1 minute.  “Allmet Continental” reached 12.9 kPa and “Talavera NB” reached 10.2 kPa.

“Allmet Continental” panels were fastened to 50 mm x 50 mm battens that were fastened to rafters through 12-mm-thick plywood deck.  The “Talavera NB” panels were fastended directly to 12-mm-thick plywood.  Sample sizes for both sets of panels consisted of 7 rows of panels with 11 full panels in each row.

4.1.5  Dynamic Pressure Water Infiltration Resistance

Note to Table 4.1.5:
Footnote 1

The test sample consisted of an eave, rake and valley assembly and measured 2.5 m x 3.1 m. It was positioned on the test frame at a slope of 1:6 and the exposed edge of the 2.5 m eave faced the wind generator.
