The eight foot shingle...

Cedar Valley: Considered the finest panels available for residential and commercial construction, Cedar Valley Shingle Panels are handcrafted with the highest grades of Western Red Cedar. Each panel is constructed with a solid one-piece plywood backer followed by a moisture barrier that's waterproof and breathable. Panels go up an average of six time faster than individual shingles, dramatically reducing installation costs. Easy installation. Overlapping end joints don't require caulking. Blind nail patterns are available. Splitting of individual shingles is virtually eliminated. And single-course panels reduce waste in gables and other tight spaces.
