Western Red Cedar Medium Shingles
Our company specializes in offering Western Red Cedar shingles, renowned for their durability and natural beauty. With a commitment to quality and environmental responsibility, we’re dedicated to supplying top-notch Western Red Cedar shingles for our customers.

Western Red Cedar Heavy Shingles
These thicker shingles provide enhanced durability and create a distinctive look with pronounced shadow lines. Crafted from sustainable sources, our shingles provide excellent weather resistance and a timeless aesthetic for any architectural project.

Western Red Cedar Tapersawn
Unlike their hand-split counterparts, these shakes are smooth sawn, which creates thicker shadow lines on the roof while preserving the clean appearance of shingles. This makes them an excellent choice for roofing projects where durability and visual appeal matter.

Western Red Cedar Perfection
Our Perfection shingles are machine-sawn on both faces, creating an architecturally uniform product with a smooth, clean finish. These 18-inch shingles combine the classic, clean look of a sawn shingle with durable performance, making them the superior choice for high-quality roofing.

Alaskan Yellow Cedar
Found only on the Pacific coast of North America, Alaskan Yellow Cedar is the hardest known cedar in the world. It has been prized by boat builders for thousands of years because of its exceptional resistance to weather and insects as well as easy workability.

Recognized by the Cedar Shake & Shingle Bureau for over 30 years

Handsplit
These shakes have split faces and sawn backs. This style of shake is the most popular and gives a textured look that can’t be duplicated by imitation products. Medium shakes are made from Premium Grade Western red Cedar with a length of 18″ and thickness of 1/2″. Heavy shakes are made from Number 1 Grade Western red Cedar with a length of 24″ and thickness of 3/4″.

Tapersawns
These shakes are sawn on both sides. Premium grade is the most common, this will ensure the product is 100% edge grain, 100% clear, and 100% heartwood. These shakes are for people that want a smooth uniform look on the roof but still have some thickness to the shake. These shakes come at a length of either 18″ (7.5″ exposure) or 24″ (10″ exposure) and with a thickness of either 5/8″ or 7/8″.

Perfections
Perfection shakes are a type of smooth sawn, architecturally uniform cedar shingle is preferred for its natural and tailored appearance and is used on traditional, modern, and non-residential structures. This product is used on roofs and sidewalls. These shingles have a length of 18″ (5.5″ exposure) and a thickness of 3/8″.
