A sampling of Red Cedar shingles

Red Cedar Shingles

Naturally durable and resistant to rot, shingles are well suited for the architectural styles of the Craftsman or Arts and Crafts aesthetic, especially the craftsman Bungalow so commonly found in the Bay Area. We carry Red Cedar shingles. Cedar is a great wood choice because it’s dimensionally stable, resists swelling, and has less splitting and cupping. Our shingles are precisely milled and refined in appearance.

#2 Grade 5x16 Available in Bundles
Bundle covers 25 square feet with 7" exposure.
