How to frame intersection of addition & existing roofs?


I have all the rafters up over the 12'x10'6" porch addition and the ridge beam extends to the existing roof. Is there a simple way to figure out the rafters over the old roof? I have been sitting up there staring at it for several days now but that's not getting anywhere. How do you figure out where the plates go on the old roof?

Without at least a picture it's hard to say.

Having trouble attaching a picture. I hope this works (and helps). I'm not sure where the boards get nailed to the existing roof for the rafters to sit on.

You need a valley board. That 2x8 you have there should work. Sight across the new rafters and move the 2x8 until the edge aligns with the tops. Your other rafters get cut from ridge to valley board. Same top cuts, reverse bottom cuts with a bevel that matches the existing roof.

I understand that the outside edge of the 2x8's should come to a point at the top of the ridge but where are the lower ends located? Do they intersect the last pair of rafters at the point of the old roof? The outside edge lining up with the top edge of the porch rafters? That sort of happens out in space so it's difficult to visualize.

Use a string line from the top to the bottom.

Valley board is not required.
