Greetings,


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
attic.


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.


Thanks!


I'm not a roofer either, but I go along with the
idea that the roof sheets are deteriorating for
whatever reason and will likely have to be
replaced. You may get away with just redoing the
West side, so just figure a that into your
purchase costs.
