I am getting ready to replace my asphalt shingles on my roof and am interested in installing plywood or chipboard over 1X6 planking on a 52 year old house' roof. Trusses are 24" apart and there is no sagging. Planks are tight (some 1/8" spacing here and there). Wood is in very good condition.
My reasons for adding a layer of plywood are to add strength to the roof. I also understand it may add some insulation for temperature and noise (I live on a semi-busy street).
I mentioned the idea of adding plywood to a contracter who came by my house soliciting a job and he said I wouldn't need to put plywood on. That the houses in the area do fine with the current planking and that there is a risk of rotting if I add plywood. I was wondering if he was just interested in a quick job or if I was getting sound advice. Any thoughts??? What would you do??? Thanks...Jim
