That's what I thought. He'll have to find a time when the weather isn't too cold or too hot & isn't raining-- which is tough in our area. It went straight from being in the 90s one day to being in the 40s the next. When it was warmer it was raining. I'll have to talk to him about the roof thing, but he'll have to save up some $ for it. He still needs to get a replacement vehicle for the truck that had the engine go. It very rarely gets below 40s here but it gets incredibly hot so heat is more of an issue than cold.He would be better served to strip the roof, fix any deteriorated decking, apply a high temp ice and water shield, then his metal roof panels. Simply putting metal over the existing mess is like putting lipstick on a pig. It will at some point fail and he will have a bigger mess.
