Problems with siding over asbestos shingle over exterior gypsum
 

Years ago I had a roofing and siding company put up siding on my home,
with "fake shake" panels for the front. The original siding is
asbestos shingles and the contractor I hired put up the new siding
over these.

The problem is that the original asbestos shingles were installed over
exterior gypsum sheathing instead of plywood. Now I'm faced with the
problem of the siding panels coming off the front of my home in bad
weather because at least some of the nails wound up breaking into the
gypsum and no longer provide good fastening.

After some discussion with some friends it seems my most likely option
is to remove the siding panels, asbestos shingle and gypsum board,
replace the gypsum with plywood sheathing and put the siding back up.
I expect this to be an expensive job, as about 300-400 square feet
needs to be replaced.

I'm wondering if there are any opinions as to whether the contractor
who did the work should have advised us of the problem, or whether
this is an unexpected situation. This contractor has been in business
for many years and I expect they should have a lot of experience. So
far they have been honoring their warranty and putting the panels back
up but I expect they will only come down if another nor'easter comes
through.

I've had the contractor do roofing work and replace windows and I
haven't had problems with that work. I'm just trying to decide whether
I should be considering them to fix the siding problem.

It will be expensive if for only the disposal cost of the asbestos. A
contractor will be required to dispose of it properly. If you get a permit
it will become a prominant issue.

I can think of a few hack ways to stabalize the shakes but ultimately you
are probably correct in wanting to tear down and replace the whole wall.

In the end, eliminating the asbestos will relieve you from having to
disclose it during sale and should increase the property value.
