This book takes you through every measurement and every cut on each type of roof so you can understand exactly what's required. The author explains how to use an inexpensive hand-held calculator to figure any common, hip, valley, or jack rafter length in seconds -- including rafters on irregular roofs and rafter pitches or lengths that aren't in any rafter table.
