this might be a dumb question or picky
removed bottom 2 courses of shingles for to replace dry rot sheathing and last row of boards under sheathing on a overhang. everything went very well
not sure why there was dry rot here right around the end of this one overhang rafter, house is 38 years old and there's about 45 rafters supporting the overhang along the house, the dry rot was right around the end of the rafter. the rafter itself is perfectly fine just the boards and sheathing, sheathing is strand board not plywood so I think this is an isolated occurrence
but back to the issue, now to nail back the 2nd (upper) course shingle, the original nails at the top of the shingle were ok to get out by rolling up the 3rd course and sneaking in the cats paw and pry bar but there's no way to get a hammer that far up to the top of the shingle to replace those nails, no matter how much I try to roll up the 3rd course
what to do?
just nail about 3 inches down from the original nails where I can work the hammer and tar the old nail holes?
or some trick to nail that far back up?
thanks for any suggestions
