If you click on this photo, you can see the old 8/12 gable and of course the new. Historical guidelines are such that this gable needs to be within the old, in set from the old walls in this case 1 foot on one side and 3 feet on the other. Looking closely, you can see that the 2x8 rafters are notched out in the overhang to achieve the same detail as the old home. This notch allows us to fasten v-groove board in the eaves within the notch, and then we went overtop all of that with our roof decking, so that when the roofers come in, their nails won't penetrate through our decorative eaves. I actually bought some reclaimed v-groove board to match the old in the eaves here. We took a couple of 4x6 timber out from a wall we did away with in the old section of the home, and cut those down to create our "outriggers" with bevel cuts on the ends to give it the same detail. You can see old outriggers (painted) in the top of the photo and the new ones are protruding from the gable end.
