Gambrel Roof Angles 45 Degree

Since the sum of the three angles in a gambrel roof is 180 degrees the angles you will need are as follows.

Gambrel roof framing geometry calculator metric this gambrel roof confines to a semicircle and starts as the top half of an equal sided octagon.

Think of it as having to go up one side turn 180 degrees with whatever number of roof angles you have and go back down the other side. Move slider or directly enter angle to alter sweep angle of lower rafters and change the shape. Check overhang to calculate rafter overhang equal to the lower level cut at the full rafter depth. They simply divide 360 degrees into half then half again then half a final time winding up with the 22 1 2 degree angle that s needed to build an eight sided roof.

A gable roof repels weather and particularly snow well. 45 degrees where the joists meet up with the top plate or header and 90 where the joists meet in the middle at the ridge board. Enter any pitch or fraction of pitch to find angle. A conventional gable roof with a 12 12 pitch will turn 45 90 and 45.

However they use a significant amount of roofing material. Move slider or directly enter angle to alter sweep angle of lower rafters and change the shape. The easiest angles for a gambrel will be 30 and 30 on each side with 60 at the peak. You will need to make 22 5 degree angle cuts on the rafter joist ends that mate up to the top plate or header.

Gambrel roofs are made up of four rafters two on each side. Each one is cut at a 45 degree angle creating four faces of the same pitch. Check overhang to calculate rafter overhang equal to the lower level cut at the full rafter depth.
