It is the opinion of the Canadian Construction Materials Centre that the evaluated products, when used as roofing materials in new and existing constructions in accordance with the conditions and limitations stated in this evaluation, comply with the following code:
National Building Code of Canada 2015
| ID | Code provision | Solution type |
|---|---|---|
| 09-26-01-02-00-0-00 | 9.26.1.2.(1) Roofs shall be protected with roofing, i ... | Acceptable |
| 09-26-02-00-00-0-00 | 9.26.2. Roofing Materials | Alternative |
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.

- Enviroshake®
- Enviroslate®
Product description
“Enviroshake® and Enviroslate®” roofing tiles are manufactured from a mixture of industrial plastic(s), recycled rubber elastomers and cellulosic fibre materials. The materials are compounded in a proprietary formulation and processed to resemble taper-sawn wood shakes and slate roofing tiles accordingly.
“Enviroshake®” is available in widths of 400 mm (full), 134/266 mm (2/3 – 1/3 split) and 200/200 mm (50 – 50 split) and are 508 mm long. Each shake tapers from 6 mm at the butt to 3 mm. Similar to wood shakes, these exposed shakes will fade to silver/grey after approximately six months.
“Enviroslate®” shingles are 305 mm wide and 508 mm long. They are stamped to resemble natural slate tiles, and the exposed section will fade slightly during the first six months of exposure.

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 product must be installed on roofs having a minimum slope of 1 in 3. The product can be installed on roofs having a minimum slope of 1 in 4 provided the solid sheathing sections are completely covered with self-adhered modified bituminous eave protection.
- The shingles must be installed over solid sheathing complying with the requirements of Subsection 9.23.16., Roof Sheathing, of Division B of the NBC 2015.
- The product is limited to installations where no fire-resistance rating is required.
- The use of the product is limited to geographical areas where the wind load, as factored for local exposure conditions and building height, does not exceed 140 km/h.
- An underlayment consisting of a minimum of two layers of Type 15 organic felt must be installed in accordance with the manufacturer’s installation instructions.
- The product must be used in conjunction with self-adhered modified bituminous eave protection extending a minimum of 900 mm up from the edge of the roof. The eave protection must be overlapped with Type 15 or Type 30 felt.
- The product must be installed with regular galvanized roofing nails of at least 38 mm in length, which must be spaced 25 mm from each side of the shake and 70 mm under succeeding courses. Full shakes require at least two nails per shake and split shakes require at least four nails.
- This Evaluation Report is applicable only to products with the phrase “CCMC 13105-R” on their packaging.
- The product must be installed in strict conformance to the manufacturer’s installation instructions.

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:
