Use ridge cut as point of reference to form birdsmouth. Calculate pitch of roof. Nail 2 boards onto your walls as top plates. Cut one end of each 2 x 8 rafter to get the necessary length desired.

Trace the top of the joint so the angle is at the same degrees as where the rafters connect. This is the first stage of the process. Cut two 2 by 4s to that length with 18 43 degree mitered ends. Calculating the pitch of a roof and making ridge cut.

Then use a saw to cut the lines that you drew. Place a 6 in 12 in 15 cm 30 cm rectangular piece of osb or 3 4 in 1 9 cm thick plywood under the joint of an assembled rafter. Determine the pitch you want for. Before you start cutting you first need to determine how long your roof rafters need to be and the angles at which you ll cut the top and bottom of the rafter.

Measure the angle cut end of your 2 by 4 and subtract that dimension from the diagonal line length. Once you located where the mark falls on the 2 x 10 measure the distance and be sure to add 10 for the overhang. Use a tape measure to measure the entire width of your building.
