NONE of what you describe in your post is used in a tile roof. What the heck are talking about?

You should find someone in your area that has done this before. This is no time for you to be learning how to do it from guys on the Internet that also and equally don't know how to do it.

OK, now it's making a little more sense. STILL, as already mentioned, there is more to this than meets the eye. I don't think DITRA is the way to go in this case.

Some Moderator should close two of those threads. Having three of them only serves to confuse and wastes a lot of time for some people. Look at the investment angus has already.
