Calculate member counts, lengths, linear metres and board feet for a measured rectangular gable or equal-pitch hip roof. Enter the roof dimensions, pitch, requested rafter spacing and timber section sizes. Complex valleys and intersecting roof planes are not auto-calculated; add them only from a verified drawing or engineer's schedule.
Quantity takeoff only. The tool does not check structural capacity, connections, bracing, deflection, or building-code compliance. Have a qualified professional verify the framing design.
