I need a bit of advice, and I know that this is the best place to get it.
A client has a 1920’s bungalo, with a shed dormer. The dormer has eaves that are about 3 feet wide, and all of the framing and decking are exposed from below. The fly rafter (2X6) is supported by corbel brackets that were custom made — looks like maybe 3X3’s which form a triangle. The decking looks like 1X4 T&G. The fly rafter is about one foot in from the ends of the decking.
The fly rafter is visibly rotted. One of the corbels also looks like it might be going bad. I agreed to replace the fly rafter on a T&M contract, and the client knows that I might need to replace a lot more than just the one piece.
I’ve replaced plenty of rotted wood, but never a fly rafter. Should I plan to use a temporary support? And if I find that the decking is also soft, is there any remedy that does not involve roof tear-off?
Thank you in advance,
