Build real job-ready roof framing skills fast with this free online course—master rafter layout, roof math, and framing tools with practical exercises.

In this free course, learn about

  • Basic roof framing equations: run, rise, pitch, rafter length, and slope relationships
  • Standard unit run for common rafters (typically 12-inch run) and how it’s applied
  • Step-off method for common rafter layout and transferring rise/run along the rafter
  • Meaning and use of unit rise in step-off layout for accurate plumb and seat cuts
  • Lean-to roof framing process: ledger, rafters, slope, and wall connection details
  • Ledger purpose in lean-to roofs: support/attachment point transferring loads to structure
  • Hip roof framing basics: commons, hips, ridge, plates, and how they tie together
  • Calculator inputs to find common rafter diagonal/length: unit run, unit rise/pitch, span/run
  • Why hip/valley layout uses 17-inch run (vs 12): diagonal geometry and length scaling factor
  • Using a framing square for roof layout: marking plumb cuts, seat cuts, and backing angles
  • Rafter tables on framing squares: lookups for unit lengths, pitches, and common/hip/valley data
  • Speed square common rafter layout: setting pitch, marking cuts, and checking angles quickly
  • Determining unit length/slope to convert pitch into rafter lengths and repeatable layouts
  • Ridge board height calculation: formula and steps to derive total ridge height from rise/run

Course Description

Roof framing can look intimidating at first, especially when angles, slopes, and measurements start piling up. This free online course is designed for beginners who want a clear, practical path into professional construction skills. You will learn how to think like a framer, translate roof plans into real measurements, and approach layout with confidence instead of guesswork. Whether your goal is to step into a new trade, support DIY building projects, or improve on-the-job performance, you will build a strong foundation that carries into many types of residential framing work.

The training focuses on the core math and layout concepts that make rafters predictable. You will work with the measurements that matter on a roof, understand why they are used, and apply them to real framing situations. By connecting basic equations to common rafter layout methods, you will learn how to arrive at accurate cuts and consistent spacing. The step-off method is introduced in a beginner-friendly way, helping you grasp how unit rise and unit run work together so your layout stays true to the roof pitch from start to finish.

From there, you will expand beyond the simplest roof and see how the same principles adapt to more complex framing. You will practice framing approaches for a lean-to roof and understand the purpose of key components like the ledger, so you can recognize proper support and load transfer. Then you will move into hip roof framing, where accuracy becomes even more important and where diagonal measurements, layout conventions, and specialized runs come into play. Along the way, you will learn when and why hip and valley rafters use a different reference run than common rafters, and how that choice improves correctness and consistency in layout.

You will also get hands-on with essential tools used on real job sites, including the framing square and speed square. Instead of treating them as mysterious gadgets, you will learn what the tables are for and how they guide layout decisions. By the end, you will be able to determine slope and unit length with purpose, calculate ridge board height correctly, and understand the formula behind total ridge height. These skills help reduce material waste, prevent costly framing errors, and make it easier to communicate with others on a construction crew.
