This was found on a one year old home.
The wood and vapor barrier are directly exposed to the sun and rain. It is only a matter of time before it leaks. This house is only one year old. The home owner is lucky this was caught before his builder warranty was up.

Hi Loren~ Every single person that buys a home, new, old or indifferent absolutely should have an inspection done! It is worth every penny! Even if a home warranty is included, an inspection is a must!
Loren, I always recommend a home inspection be done at least before the end of the first year on a new home.
