Don't Overlay Shingles
To the Editor:
Regarding a question about
overlaying asphalt shingles (On
The House, 10/92): most shingle
manufacturers will void the warranty
in an overlay application.
I can tell you from personal
experience that if you do have a
warranty claim of any kind, once
the company rep sees that it is an
overlay, he will just turn around
and walk away.
There are many premature roof
failure problems associated with
uneven roof decks and it doesn't
make sense to tempt fate with an
overlay. If a roof is worn out,
chances are it won't make a good
surface for new shingles. Get out
that stripping bar and get rid of
the old roof!
