Just replaced the roof and this winter I will be tackling the damaged sections of the interior. No worries on the process just material location. I see sheets offered online for $20- 30 each and am assuming the shipping on 2 or 3 sheets would be out of this world. Are the panels made from 50" plus vinyl material as mine apper to have no seams. I can get 24" rolls at the home center and cover luan that way but it seems like a lot of extra work. I will definitely use plywood sealer on the back of the sheets.
Thanks for the suggestions above.
