I'm a DIY roof fixer on a 50-year-old ranch-style house in upstate New York. The roof is in pretty good shape, but some of the tricky parts of the roof (chimney and a major valley) are not done according to the DIY books. The chimney is holding up if I keep the leaves from building up, but the valley is leaking (again). I fixed it for a few years last time with some careful tarring, but I read up enough to know that the valley should have a flashing under the tiles that is two-feet-wide, a foot up each side under the tiles. There is no such thing. As best as I can determine, the original roofer brought the two slopes together and put down a tar and tape 4-inch valley. I don't want to rip up enough tiles to do this right, at least until I am looking at reroofing in general, so what is next-best? 1) just keep tarring holes 2) run a tarring-tape down the valley and tar over it 3) a 4-inch metal flashing, tarred down 4) duct tape, tarred over 5) flashing tape, tarred at the edges 6) something else?
