16522 Arena Dr Flat tile roof inspection

Thanks for the video, we use a similar tile here in Ireland 12x16" we would allow 4" for headlap.a pitch of 22.5 minimum. We don't use ply wood at all, just a breathable membrane felt ontop of the rafters and then 2x1 treated batons fixed parallel at 12" spacings the tiles should have lugs that allow the tiles to hang from the top edge of the baton then every 2nd tile only is nailed. Doing it this way leaves a cavity under the tiles any possible water ingress can flow down the felt and into the gutter without lodging behind and sitting on the under felt.

Here in the UK some houses have still got their original concrete tiles on and they are nearly a hundred years old and the roofs are still bone dry
