I am planning a shed-roof (not gable) workshop and would like to have a 2' rake overhang. I know the standard way to frame this would be do to 16" or 1' and support it with blocking, the rafter tail/ridge, and the plywood sheathing.
For a longer overhang, that is not sufficient. What strategies can be used to support a 2' overhang without hurting the structural integrity of the last rafter (which needs to remain in-tact since it is cantilevered, as you can see in the design).
Best Answer
Double the second rafter in (first one in is the one over the wall) and instead of blocks supporting an overhang, run 2X from the doubled rafter over the sloped wall and connect to the overhanging rafter. Fill in with blocks between the cantilevered 2X to close those areas in.
Another way is a take on the same thing, but using 2X4 set flat into notches (lookouts) in the top of the rafter set over the sloped wall. The under side can be filled in with short blocks to carry finish material under the soffit if you choose.
