Here at the Womb I built the outdoor lanai roofing with plywood, tarpaper and asphalt sheeting.
It is totally water proof and the full thatch covering is just for show.
I got just under 5 years with the first thatch here in Los Angeles and just recently replaced it. It held up longer than I thought it would.
No problems with rot or anything under the thatch.
I also have a corrugated steel roof that comes off the main roof to cover the cooking area and it makes a nice complement to the thatched roof.
