outdoor carpet on the roof

[Jerry Peck - Codeman]

From and e-mail question:
Our condominium has covered our entire rooftop with outdoor carpeting. it was approved by the nyc dept of bldgs and the c/o was issued .

Naturally, we were reported by our grouchy neighbor for noise on the roof and low and behold, a bldg inspector cited us for having "combustible" material on the roof.

Is their any proof that outdoor carpeting material is in fact not "combustible"?

Lets face it, it may be flammable, but it cannot be any more combustible then the tar and roofing material and flashing lying beneath the carpet. If I can show some evidence of such then the violation may be dismissed...otherwise we'll have to remove many many square yards of material and expose the roof.

any help?
