I can't share the actual detailed drawing with you, but I can tell you that the rake board is 5/4 x 8 Azek with 1 x 3 Azek applied trim. There is also a 1" copper drip edge along the top of the rake. The rake projects about 18" beyond the building wall.

Completely understand! Those dimensions are perfect for reference. Much appreciated!

Also, I should mention that the soffit material is Azek tongue and groove bead-board.

Keep in mind, it's all a matter of scale and proportion. On this particular project we used a 5/4 x 8, but on others we've gone smaller or larger depending on the overall scale. As a point of reference, this particular garage is 18' wide.

Absolutely! I think that's why I'm struggling so much with my own decisions. The 18" rake projection is definitely more than it appears in the photo. I'm trying to make selections that will give some character to a modest ranch/almost cape-style, without overdoing it.
