Haven’t done a lot of metal roofs and so hoped someone could answer a couple questions for me.
Did an inspection today on a house built in 2006 that had a metal roof. While in the attic, I noticed that there was no plywood or OSB sheathing/decking between the rafters and the metal sheets. Is this allowable/correct? All the metal roofs I have seen have had some sort of decking, but then again, most of those roofs were installed over an already existing roof.
Also, there was a vent pipe that didn’t go through the roof. I assume that is incorrect for a metal roof as it is for a shingle roof.
Any help would be appreciated.
