Hi,

The wife and I put a bid on a new house and we just went through it
with the engineer. This house is a split level, and while checking the
attic crawlspace above the master bedroom, he noticed that the plywood
on the roof looked a little damp and there was mold growing on the
wood. The insulation is blown in and whoever did this never installed
any kind of vapor barrier. Now my questions a

1) How hard would it be to install a vapor barrier? I know everything
has to be sucked out, then the barrier has to be installed, then new
insulation has to be blown in. This sounds pretty tricky since the
only access is the attic crawlspace and I don't believe the joists
would handle a lot of weight.

2) I don't believe I saw any soffits on the outside of the house.
Would adding soffits and making sure there was adequate airflow in the
attic correct the problem?

I know we're going to be busy taking care of a lot of things when we
move in, so I'm not going to have much time to take care of this
stuff; and I want to get this taken care of ASAP.

Does anyone know approximately how much this would cost to have it
professionally done? We might be able to get this cost taken off of
the offer. Thanks for any help!
