You have me doubting myself now...
I used the housewrap as directed on the Tyvek diagram:
The air gap between the roof and the membrane is open to the eaves so any water should run to the eaves and evaporate from there with the airflow, similarly for the walls I have drilled through the timbers up to the eaves and I think I will add some ventilation by drilling through from the outside at the bottom of the frame.
its not that it wont evaporate its that youve had the roof off id have had the roof sheets going to outside above over the wall
this pic is correct
its these 2 that im questioning any water off the roof should run over your wall points to outside of the building
these appear to run the water onto the inside of the wall where the black and red arrows are so any due or water droplets will collect on the inside of your insulation
