Help! What's wrong with this roof? We are considering buying a house
that is 6 years old. We have through Monday to make our decision. The
house is in perfect condition.. except for the roof. There are no
leaks/moisture spots in the house. There are no leaks visible in the
PROBLEM: Quite a few shingles are slightly raised. Not buckled, or
warped, just raised slightly --at random-- primarily over the west side
of the roof. One area of the roof appears wavy. Almost all the aluminum
drip caps --where they overlay the other drip caps-- are raised by 1/4
inch. The drip cap ends are raised enough to start making inverted "v"
indentations in the shingles above them.
None of the other roofs in the same neighborhood --the houses were all
built at the same time-- have the same problem. All their shigles are
flat and their drip caps are not raised.
There is a bonus room built in the attic and I am wondering if there
isn't enough ventilation.
