I'm building a garage and want to use 2 x 6 rafters gable roof. How do I figure the length of the rafters and the angle of the plum and seat cut? I'm just pouring the slab. Then I'll build the walls and then the rafters, decking and composition roof.
The span will be 20 feet and the rise I guess around four feet.
I know I'm on the right track but can't remember how it goes
Oh and a one foot overhang!
and maybe an ingrown toenail!
lol
Thanks!
