Appendix I: Small Mock Roofs

This appendix documents the design of three commonly encountered roof types: composition shingle, flat concrete tile, and one-piece S-tile. The small mock roof is based on two 4 ft. × 8 ft. × 3/4 in. sheets of CDX plywood and 2 × 4 studs on 16 in. centers.

This is a snapshot of the Google SketchUp model for the small mock roof.

This is a picture of a stack of framed small mock roofs. Each of the roofs will be covered with 30# felt.

This is a small mock roof with 30 lb. felt and furring strips (a/k/a battens), finished with S-tile. The furring strip spacing is dictated by the length of the tile and the required tile-to-tile overlap. Note the nail in the upper right-hand corner of this image that shows how the tile is attached to furring strips.

Small mock roof with 30 lb. felt, furring strips, and flat concrete tile. These tiles have been laid out without nailing. However, two holes at the tops of each tile can be clearly seen, which can be used for nailing to the battens.
