Barb...will you be putting an overhang on the sides...?

If so, you will need to cut out a "bird's mouth" in the part of the rafter where it intersects with the wall. The bird's mouth will sit on the upper horizontal 2-by and then the rafter gets toe-nailed.

Take a look at this site for all the particulars...angles, lengths, overhang, bird's mouth, etc... It also has a calculator for all the components for different style roofs.

Good luck...

Barb...just be careful to not over-prepare the lumber...some things are best left for "at-the-time".

For example...the rafters shouldn't be cut until the walls are framed and up and the ridge beam is up. Reason being that you need to know the exact measurement of the ridge to the top 2-by of the walls (rafter length)...and the distance may change a bit from one side to the other depending on how accurately the ridge beam was installed...then you can more accurately cut the bird's mouth and overhang so there are no "wavey's" in the fascia board.
