I have a leak in a valley on my cement tile roof(flat interlocking). I climbed up to investigate and noticed that there was a channel in the valley (approx. 4" wide). I lifted a loose tile and noticed that the felt paper around the channel was very deteriorated. It would crumble when touch in the hand. I want to do the repair myself. I just need some clarification on a couple of things. Here is what I plan to do and tell me if it is correct.
I'm going to:
- Remove the tile on each side of the channel from the top to the bottom. I'll go as wide as I need to until the felt looks good and go one more.
- I'll remove the old channel. It looks like it is in good condition. If I can reuse it I will.
- I'll remove the deteriorated portion of the felt.
- I'm not sure but, there is probably some type of nail board that the tile gets nailed to. If I need to, I'll remove them to.
- I'll repaper the valley going across from to to bottom overlapping
- I replace or reinstall the channel.
- Replace the nail boards (If I removed them.)
- Reinstall the cement tile. Replacing any broken ones.
I'm I off base on this. Please guide me in he right direction.
Thanks in advance
PS the channel is about 10'-12' long.
