Angle of roof

To all you kind people:

I am going to build a building that is 62' x12', with one roof. how do I calculate the angle at the peak of the roof, so it encapsulates the whole building? John

Use the Pythagorean theorem. You know the base of the triangle will be 6', and the overall rise will be ?? feet. (6 x 6) + (? x ?), then take the square root of the answer, then add the overhang, which is usually 12 to 18".
For instance, you want a 8:12 pitch, your calculation will be (6 x 6) + ( 4 x 4) or 36 + 16 =52. The square root of 52 is approx 7'1". Add your overhang of 12" and the rafter will be approximately 8', taking into consideration the thickness of your ridge beam.

Angle

Tell us the roof pitch and we can tell you the angle.

Is this a gable, dual pitch roof or single pitch shed roof?
