Here at Deep Green, we often shine a spotlight on traditional building materials that have fallen out of favor for a variety of reasons—but that we believe deserve reconsideration by today’s architects and designers, especially those concerned about the environmental and social impacts of their projects.

Slate—a gray, flaky signifier of 19th-century luxury—for example, is one that we think deserves a second look. Before the 1930s, when asphalt composite shingles became the most common roofing material in North America, the middle class was rushing to build Victorian-style homes or renovate their Georgian and Colonial-style mansions with slate roofs.

And there was a reason. Slate was easy to maintain, elegant in color, and excellent in thermal performance. Many beautiful buildings around the world still prove its durability, with roofs that have lasted hundreds of years. No wonder there was a slate boom in the 19th century—not only in North America but in many other parts of the world where slate roofs have been constructed for thousands of years.

In this episode of Deep Green, created in partnership with CUPACLAD, host Avi Rajagopal sits down with Drew Ford, USA regional sales manager for CUPACLAD, one of the world’s leading slate providers. Listen in to learn what makes slate a great choice today and what new possibilities have opened up for this ancient material.
