Hi:
I have a very leaky tile roof, which had been "repaired" a few years ago, but now it's leaking again. Only the paper was replaced, and it seemed like the thin regular kind. The major problem is the pine needles that block the channels in the tiles and i was told normally that wouldn't be a big problem except that the roof isn't steep enough.
I wish I had done more research in the past, but after doing a little more, I find out that there is something called self-adhering underlayment which is supposed to do a better job of keeping out water especially on less steep roofs. Replacing the entire roof with shingles would cost too much becuase it is a large single story ranch. Repairs would cost much less but I would like to know what I should be asking for in material when I contact a tile roofing repair specialist. With tile roofs, it's pretty much the underlayment and wood that needs to be replaced, the flashings in the valley and damaged wood.
So my question is because of the pine needles and the pitch of my roof, is there any way to reliably water and leak-proof it or would I have to go the shingle route? I was wondering if self-adhering underlayment along with synthetic paper would do the trick. And would copper valleys do a better job of water-proofing than the stainless steel ones I have?
Thanks
