Lay 18" course (row) of tar paper across entire length of roof, attach with roofing tacks. Install shakes from left to right (leave 1/2" between for expansion), drive in 2 long roofing nails about 1" up shake (next row will hide nails). First row hangs 1 1/2" over gable and 1" over fascia. Repeat same to apex, use cedar ridge-cap.
