metal roof no sheathing

HI there We are in contract on a new construction home with a metal roof. We have just learned via the inspection that it has no sheathing underneath it. There is an attic and I am assuming the attic ceiling is insulated however most folks we have spoken to have said this is not a good idea for a variety of reasons including condensation, noise control or protection against bad weather. I am wondering why a brand new home would be constructed in such a manner and if it will be a good long term and safe investment. Thank you!

I am generally not real fond of this sort of residential application but that said, with things like vapor barriers, ventilation, proper insulation, it can work. So, this is a home that is finished but it's a new home? Am I understanding that correctly? So, there is no track record really as to whether any condensation issues have occurred? Any information you can provide on vapor barriers, insulation, ventilation, and whether all things like bathroom vents, dryer vent, kitchen fan, are properly vented to the outside will be helpful in telling you whether I have any major concerns.

Todd Thank you so much for your prompt reply. It is brand new construction. No issues with condensation that I know of as we are not in the house yet. I can gather information on vapor barrier, insulation, ventilation , bathroom vents, dryer vents and kitchen fan are properly vented. I s the vapor barrier in ceiling (flooring) of the attic? Sorry I am new to all this. We live in asheville NC and it rains a lot here as it is a temperate rain forest. Honestly, wishing for the price it had the decking that seems to be what is recommended. :( Beth

Thanks. The condensation I am concerned about would be from moisture that originates inside the home. That really doesn't "kick in" until the home is lived in. The moisture comes from bathing, laundry, house plants, cooking, etc. Even breathing. :-) However, that said, climate plays a role as well and you're in a tough climate for condensation. Chances are if you have a vapor barrier it is between the ceiling drywall and the insulation. If it's easier, feel free to email me at [email protected]
