If you over cut the birdsmouth notch the length and load capacity of the cantilever rafter tail is reduced. Sep 01, Cut 70% notch into the tree with the length of 80% of the trunk’s diameter.

Calculate pitch of roof; Use roof pitch to cut ridge cut; Use ridge cut as point of reference to form birdsmouth; Make tail cut; For the purposes of this project we are going to be working with a simple gable roof e.g. pitched roof, with a central ridge. Calculating the Pitch of a Roof and Making Ridge Cut. This is the first stage of the process.
