The Alaskan Yellow Cedar overhead sits under two layers of Meranti 1088 marine plywood, then a poly-fabric and elastomeric (Metacrylic) decking system is applied. Once it has dried, the final deck of canvas will be applied and painted. The painted canvas deck will carry the appearance of “tradition”, have a slightly non-skid texture, but this underlying elastomeric roofdeck material will ultimately provide the flexible watertight deck we need. Here in this picture, you can see on the raised deck in the foreground that the marine plywood was laid on the diagonal for increased stiffness.
