Product information
Product name
MetalWorks® StoneCrest® and MetalWorks® AstonWood® Steel ShinglesProduct description
The products are intended to be used on residential and light commercial buildings falling under the scope of Part 9, Housing and Small Buildings, of Division B of the NBC 2015.
The products are sheet-metal roofing systems consisting of a basic panel that is pressure-formed from 0.37-mm zinc alloy sheet steel that is finished with a fluoropolymer coating (70% polyvinylidene difluoride (PVDF)). The underside is finished with a corrosion-resistant coating.
The products have a nominal measurement of 1 010 mm × 320.5 mm. The panels are constructed with a 4-way locking system and installed with a concealed nailing clip.
The longitudinal cross-section of the MetalWorks® StoneCrest® Steel Shingle consists of 5 modules, each with a stone-embossed profile.
The longitudinal cross-section of the MetalWorks® AstonWood® Steel Shingle consists of 6 modules, each with a wood-embossed profile.
Both systems include accessory strips for hip and ridge cap, valley pan, gable and flashing.
Typical installation details and nailing clip for the products are shown in the following figures.

Product evaluated by the CCMC Indicates that the product from this manufacturing facility has been evaluated by the CCMC
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 4.
- 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.
- This evaluation report is based on the use of one layer of Type 30 organic felt underlay. This may not meet the underlayment requirements of the manufacturer at all roof slopes. Refer to the manufacturer’s installation instructions for proper underlayment usage.
- Only fasteners and accessories supplied by the manufacturer must be used with the products. The fasteners and accessories must be compatible with the base metal of the panels.
- The roofing system must be installed in strict conformance to the manufacturer’s instructions.
- The roofing systems are for use in locations where access is limited for maintenance or repair purposes. When access to the roof is needed, temporary walkways or roof boards are recommended to avoid any permanent damage to the panels.
- The products or their packaging must be clearly identified with “CCMC 13011-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:
