Synopsis

Master roof framing with the Steel Square. Learn practical, reliable methods you can apply on the job. This edition lays out clear, step-by-step techniques for using the steel square to find miters and sides of polygons, calculate roof pitches, and lay out rafter, hip, and valley cuts. It emphasizes concrete measurements and visual references, so you can translate angles and lines into exact timber lengths.

From basic polygons to complex roof features, you’ll discover how to work with 36-degree and other common angles, determine correct run and rise, and produce precise bevels for joints. The instruction uses diagrams and practical rules to help you transform a roof plan into workable timber layouts with confidence.




  • Find miter lines and side lengths for triangles, pentagons, hexagons, octagons, and more using simple steps on the square.

  • Determine roof pitches and corresponding run and rise values, for common rafters, hips, and valleys.

  • Calculate bevels, plumb and heel cuts, and jack rafter lengths for different roof pitches.

  • Project roof layouts from pitch to finished timber lengths with scalable methods and reference figures.



Ideal for carpenters and roof framers seeking practical, hands-on guidance to simplify complex framing tasks.
