I will try and address some of the comments made…
The 8+ " of insulation is just a guess based the drawings that were present and the way the attic was layed out. This was a very unique custom built home. The designer/builder actually lived it for a couple years after it was built. There may have been less insulation but probably not much less. Anyway, the amount insulation was not in the report. It was merely stated to say that I felt the insulation was more than adequate.
I would say it is definitely not hail damage. I have seen plenty of hail damage and this is not. Besides from on top of this 2nd floor roof I had a very good look at the neighboring houses roof( houses were only about 8’ apart ). One was a standard 3 tab and much older than this roof and had no damage of any kind. So unless hail only hit this house it is very unlikely hail is the culprit.
I kept the comment about manufacture defect out of the report and have heard a roofer went to look it over and thought it was a manufacture defect anyway. Right now the agents are working on contacting the manufacture to see what can be done.
After some more research it does not appear that spray foam will void the warranty, however if the statement that the warranty will not transfer then it is game over anyway, the current sellers are the 2nd owners and my client would be the 3rd owners.
I would like to thank all you responded to this.
