About Us

Cedar Valley Handcrafted Shingle panels offer hand laid shingles in lap siding form. We start out with real Western Red Cedar shingles and hand apply them to a strong & stable plywood backer. We have construction grade adhesive & two sets of concealed staples to complete our exclusive industry leading siding panel. This system has been proven in the field for over 35 years and is fully accredited with numerous tests and code approvals including: California State Fire Marshall Wildland Urban Interface fire code; Texas Dept. of Insurance & State of Florida approvals. Panels are certified for wind uplift ratings of up to 210 mph along with the ability to meet any fire rating required including Class A. Our system also has incredible design flexibility with options including but not limited to; ½’’ thick butt shingles; radius flare corners; radius wall details; custom & mixed exposures; Factory-finished material with unlimited color range & stain options. We also manufacture other Western Red Cedar products including Clear VG T&G paneling and Trims. Our unique manufacturing process allows us to "stretch" the supply of old growth cedar by using 2 to 6 times less WRC than traditional products.
