Any pictures of the home? If you are sealing up the roof design and adding foam, you may not require any venting of the roof at that point.
Hi, I have a 16x80 mobile home with a 3 12 pitch shingle roof. The shingles are still in decent shape so I'm going with metal over the existing shingles; I plan to install the metal sheets over the cedar planking. Should I use underlay before fastening the planks to the existing roof? My concern is condensation.
Correction; the roof is 2 12 pitch not 3 12.
Make sure that the metal panels you install are approved for 2:12 pitch. You will want a layer of underlayment on top of the decking beneath the metal roof panels. You could consider a breathable underlayment ... I know that GAF makes one, and there are some others out there including one called VENT3.
