While we are on sheathing…. normally, what supports the sheathing at the overhang ends of the trusses. Nothing fancy….4-12 pitch roof. Trusses on 24″ center. What keeps the sheathing from sagging between the trusses along the facia part of the roof. The reason I am asking is I am getting ready to reroof my 24 year old house and I am finding that the sheathing stops about 2″ short of the facia where the gutters mount. This leaves a gap that the shingles have to cross and over the years they have developed a pronounced dip at that point. Also, the sheathing has sagged some between the trusses, although not as bad as you would think. The “cardboard” facia needs to be replaced anyway so I am open to suggestions as to how to do this all at one time. I have plenty of overhang, so my thoughts are to strip off the bottom few shingles, snap a line, and cut off all the trusses even with the end of the sheathing. At the same time, I would cut them so that the facia would be verticle instead of at an angle. Would make mounting new gutters a lot easier. The only thing I am having a problem with is how to support the sheathing where it butts up to the facia. It would be a lot of work, but I thought about attaching some 1x stock to the back of the facia to support it, what do you guys think ?
By the way…not too many laughs please….this is not a “Fine Homebuilding” house by any means, just a 24 year old tract type house. I am surprised that the roof has lasted this long in as good a shape. I cannot seem to get the “file attach” feature to work, so here are links to two pictures that show the situation pretty well.

we use a sub-fascia of 2x4 and a finished fascia of 1x6 ..
in you case, looking at the pics , you could simply replace your fascia with a new one and bridge the gap with aluminum drip edge that should have been used anyways..
if you wanted to use a sub-fascia , you'd have to get into redoing your rake trim too, so you may want to just leave it at replacing the fascia and adding the drip edge.. run your drip edge up the rakes also..

Mr. Bill. Oh NO!
That fascia sure look like baseboard to me. Really?
Since you are stripping the shingles and probably going to expose the sheathing too, it would be a good idea to check the roof, replace any bad wood and do a little renailing while you are at it. When you get to the edge, I would strip off that fascia, make sure that the rafter tails are all in a straight line and then ADD a 2x sub fascia to the ends of those rafters. How you detail the ends of those tails is personal preference, plumb cut as you mentioned or square cut as they appear to be now. With a plumb cut, the angled cut will be longer so I would use a 2x6 sub fascia with an angled rip on the top edge to match the pitch of the roof. I also add a 1x2 PT to space out the drip edge from the finished fascia. Plumb cuts and the rips on the fascias are a little more time consuming but this will give you support and an outer nailing edge for the new strip of roof sheathing you would put on. If you have board sheathing, select and rip to width a 1x board. Looks like a 1x6 should do it. Plywood? Rip a strip and use a plyclip between the trusses. You might also consider ripping off a strip of the existing plywood to remove any dip or bad wood and go with a wider replacement rip. Felt the roof and add the drip edge (which you don't have now). Your location will determine the recommended procedures, ie. ice and water or just a strip of roofing cement all around. The actual width of the sub and finish fasia you use will in part be determined by the look you want and whether or not and how you will finish the soffit.
Mr. Bill:
Great advice already given. Would also recommend considering 2X subfascia; wrapping it around the return should gain enough height so existing rake boards can be trimmed to intersect. Suggest also not assuming that all the sag is from the plywood itself: measuring your cuts out from the frieze instead of measuring up from the existing ends...

ssubfascia is the answer to this problem.
The thing that amazes me is why any roofs were ever built without it..
Excellence is its own reward!
