I consider doing frame repair much like roofing repair work. The newbie sees a small hole through the shingles and makes all kinds of plans/assumptions with this view. Then the shingles are removed at the hole, then the underlying sheathing is found to be bad so more shingles come off. Then the sheathing is removed and one finds the rafters are rotted. by the time all is done and over the little 4" hole has become a 10' area of new shingles and all.
The current frame repair i'm doing, posted on C&V (
