I have an old stable on my property that I plan to use as a metalshop. I pulled away the old gutters today and found the fascia had nearly rotted away. Most of the rafter tails have at least a couple inches of rot in them, though the end of the 2x4 lookouts seem okay. The plywood soffit sheath is half-rotted, from the inside-out. See attached photo. I can sister new ends onto the rotted tails, but cutting the old rot away will require removing the lookouts. So I was thinking perhaps to just rebuild that part of the roof with square-cut rafters, skip the lookouts, and put in new soffit sheathing. Anyone here with some framing experience? Was wondering if that sounds right. I was going to replace everything with PT lumber, kiln-dried. Thanks.
