Grist Slate & Tile Roofing Inc. was recently awarded the 2023 North American Copper in Architecture award for its work on Vancouver's Heritage Hall envelope and seismic upgrade.

GAF Time-Release Algae-Fighting Technology is comprised of specially-engineered capsules that release copper steadily over time.

Sheet metal contractors are encouraged to submit projects completed in the past three years in the U.S. or Canada that feature copper architectural elements.

The Copper Development Association awarded 12 innovative copper building projects in the United States and Canada as part of its annual North American Copper in Architecture (NACIA) awards program.

This year's award program will increase a focus on green and sustainable building strategies using copper.

A complicated copper project earns a long-time roofing contractor high praise and international recognition.
