The house was originally built in 1987 with "Thermoply" sheathing (a 1/8 in
thick silver surfaced material which meets local code - Ryan Homes still
uses the stuff) with vinyl siding over the Thermoply. I had never had a
problem (other than fading and getting tired of the color) with the original
vinyl siding for 16 years (I suspect the siding was nailed to the studs).
The new siding was installed over a layer of Tyvek wrap and a layer of 1/2
in foamboard nailed over the Thermoply which is the normal procedure for the
contractors from whom I had gotten estimates.

A piece of siding in one of the two areas pulled loose within a year of the
installation and the contractor nailed it back up. Now, after 2 1/2 years,
siding in the same area and also in another area were pulled completely off
the house. I'm sure the heavy winds were responsible for the siding being
pulled off, but my problem is that there was very little similar damage to
other vinyl clad houses in the neighborhood (most of which were built with
1/2 in OSB) or in the general area, but mine sustained considerable damage
that seems out of line with what happened in the surrounding area. I
suspect that when the new siding was installed that it was not nailed to the
studs as I had assumed, but just through the foamboard and into the
Thermoply and that is why the nails pulled out. I am currently trying to
find out if there are any local codes addressing the installation of vinyl
siding over Thermoply and if there is, and the contractor didn't install the
siding according to code, I will persue the matter, otherwise I will try to
have it taken care of through insurance.

I am putting a lot of time and energy into this rather than just relying on
insurance because I feel I spent good money to have a job done right and if
it wasn't I think it is up to the contractor to make it right. Besides, if
everyone relies on insurance to correct poor workmansip by contractors,
everyones insurance rates will go up - also I would have to pay a $250
deductable.

Thanks to those who commented,

Do you know the manufacturer of the siding you got?
They've probably got installation instructions. Get
those, and compare them to what you actually got.

While you're at it, send pictures to the MF,
and see if they have any theories.
