We use a unique design called tongue and groove that shingles are attached to. This is a more expensive pattern that provides a more finished look because the underside of the shingles cannot be seen. Using 1x4 boards, we fit together a solid ceiling. We then use roofing felt over the top to serve as a vapor barrier. We then finish this with Western Red Cedar ridge caps applied along the seams of the roof to keep any water from entering. This way, you can enjoy the natural beauty of your Cedarshed from both inside and outside!
