I am re-insulating my 1.5 story attic space. All of the closed cell spray foam contractors I have talked to say that the best way to do it is to spray the foam against the roof decking and create a perfect seal. They say that it is not practical to try and ventilate an old 1.5 story, 2x4 built roof with no eaves to speak of. It just doesn't work, so it is better to seal it all up tight.

The city on the other hand, says that NO HOT ROOFS ARE ALLOWED, claiming it is state code, despite the fact that all neighboring cities allow them.

What should I do? Keep fighting the city? Is there another workaround to this?

Thank you!
