From the IRC;
Roof decks shall be covered with approved roof coverings secured to the building or structure in accordance with the provisions of this chapter. Roof assemblies shall be designed and installed in accordance with this code and THE APPROVED MANUFACTURER'S installation instructions such that the roof assembly shall serve to protect the building or structure.
Now, if the roof covering is installed up-side-down, seems to me this would invaladate the manufacturers warranty, thus be uninsurable.
Just wait til the first bad storm comes through and causes damage to the area and the insurance adjuster has to make a determination of the claim. I can see it now. CLAIM DENIED!! Roof installation was not per manufacturers recommendations-- primary cause of damage.
Ouch. You might be getting a call on that one.
