I am a first time home buyer and looking into buying a new home. My wife and I have found the perfect home here in Maine, but found out today that the metal roof was attached directly to the perlins. I know typically there is supposed to be sheathing and a vapor barrier in between. I have found information on both sides of the argument, which have led me here. Is no sheathing adequate? How will it affect my energy use? and will it be a condensation issue? Is this ok for a cold climate here in Maine?
I was inspecting the attic with my realtor and we did not really find any evidence of water leaks anywhere in the beams or the insulation except for one spot (pictured). Also there are no sophet vents, but you can see daylight coming through the eaves. My realtor snapped a picture and sent it to the inspector he works with. According to the inspector who looked at the picture, he said it looks great and there is nothing to worry about.
I would post pictures, but cannot find the paperclip to attach them, so i just uploaded them to a picture sharing site:
I’m still unsure and would really appreciate somebody’s second opinion on this issue.
Thanks for your help
