Evaluation

CCMC 10475-R is an evaluation report that confirms compliance with the Canadian Construction Materials Centre’s building codes, specifically for Interlock Roofing products. This report includes detailed testing and performance results for Interlock’s Slate and Cedar shingles. It covers various aspects such as traffic load, wind uplift, and dynamic pressure water infiltration tests. The results demonstrate the shingles’ ability to withstand significant pressure without deformation or permanent damage, and their effectiveness in preventing water leakage under various wind speeds.

This evaluation is crucial for ensuring that the roofing products meet the stringent standards set by Canadian building codes, emphasizing safety, quality, and durability. Such compliance is vital for roofing contractors, architects, and homeowners who require reliable data on the long-term durability and environmental integrity of roofing products.
