Diffusion-open roofing underlayment

[Acora]

Dear Friends! Hoping to be saved from my total indecisiveness...

Well... House built in 1940. The roof is in the worst condition and needs to be replaced. Currently, there is masonite on battens nailed to the rafters, then support/intersecting battens and tiles on top.

The roof is 120 m2 and has a slope of 46 degrees. I live in Trelleborg where snow is rare. Inside: sparse/rafter/insulation/air gap that was nailed when we tore down the cold attic. We knew the roof would be replaced soon,

got a tip and idea about the roofing membrane. This will mean I will remove the air gap and possibly insulate a bit more. Looked at TECCA T Diff-PRO. Thought about using board from the start but it generally feels shabby. Air gap just messy etc. Raw board and ply are not an option.

what should one do???

Many, many thanks in advance

Determine the outer roof before deciding on the inner roof as the requirements vary depending on whether you have, for example, interlocking tiles or non-interlocking tiles.

Sorry forgot to write. Already decided, it will be folded single-paned tiles.

Sorry, forgot to write. Already decided, will be interlocking single-cup tiles.
