1. Opinion
It is the opinion of the Canadian Construction Materials Centre (CCMC) that “Allmet Granite Ridge, Guardian Shingle”, 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 materials)
This opinion is based on CCMC's evaluation of the technical evidence in Section 4 provided by the Report Holder.
2. Description
The "Allmet Granite Ridge" panel is formed from a 0.42-mm-thick aluminum-zinc alloy steel sheet metal and the "Guardian Shingle" panel is formed from a 0.34-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 base coat onto which mineral aggregates are spread and covered with an acrylic overglaze. See Figure 1.

The panels are 1 170 mm x 397 mm of which 1 118 mm x 348 mm is exposed. The panels are designed to resemble traditional asphalt roofing products. See Figure 2.
The complete roofing system includes accessories such as the starter strip, rake cover, hip and ridge cover, valley and valley cap, riglet, and Z-bar.
3. Conditions and Limitations
CCMC's compliance opinion in Section 1 is bound by the “Allmet Granite Ridge, Guardian Shingle” 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 are permitted to be used in conjunction with the products and they must be compatible with the base metal of the panels.
- The roofing system must be installed by manufacturer-approved installers in strict conformance to the manufacturer's instructions.
- The roofing system is intended 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 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
Under an applied load of 890 N, the panels withstood the force without permanent distortion.
4.1.3 Wind Uplift
| Pressure (kPa) | Requirement | ResultTable 4.1.3 footnote 1 |
|---|---|---|
| 1.4 | No evidence of deformation, permanent damage or failure | Pass |
| 2.9 | No evidence of deformation, permanent damage or failure | Pass |
| 4.3 | No evidence of deformation, permanent damage or failure | Pass |
| 9.1 | No evidence of deformation, permanent damage or failure | Plywood fastener pull-through |
Note to Table 4.1.3:
- Footnote 1
-
The panels were installed on top of Type 30 organic felt that was laid over 12-mm, Grade B-C APA rated plywood. Each panel was fastened to the plywood with seven No. 8-14 32 mm screws. The plywood was fastened onto 50-mm x 250-mm joists that were spaced 600 mm o.c. using No. 8 coarse thread screws.
4.1.4 Dynamic Pressure Water Infiltration Resistance
| Wind Speed (km/h) | Simulated Rainfall (L/m2·min) | Duration (min) | Requirement | ResultTable 4.1.4 footnote 1 |
|---|---|---|---|---|
| 50 | 3.4 | 15 | No leakage or damage | Pass |
| 110 | 3.4 | 15 | No leakage or damage | Pass |
| 140 | 3.4 | 15 | No leakage or damage | Pass |
| 170 | 3.4 | 5 | No leakage or damage | Pass |
Note to Table 4.1.4:
- Footnote 1
-
The panels were installed on top of two layers of Type 15 organic felt that was laid over 12-mm, APA 32/16 span rated sheathing. Each panel was fastened to the sheathing with eight 9.5-mm x 32-mm galvanized ring shank nails.
