    I have a Carport at the rear of my property where I store my caravan, the majority of the caravan is covered by box profile sheets, at the front 3 foot I placed featherboard on the roof thinking it would keep it dry (silly me) my intention is to take the featherboard off and replace with a 6 or 9mm plywood and covered with Felt Vent breathable and then replace the featherboards.

    My question is, after placing the ply, felt and featherboards will the roof be waterproof (no drips coming through)

    All constructive help greatly appreciated
