Spray foam causes moisture problems in the roof line. The problem with that solution though is that it violates the building code for an attic with exposed spray foam insulation.

The foam will also contract and expand depending on the weather which again reduces cracks. Even small gaps can allow the passage of warm air through the foam rendering the foam all but useless as an insulator. If you directly condition the attic however now you need a thermal barrier and no builder s gonna do that. While this does not pose a health concern it is a concern for surrounding property.

With a spray on roof you can fill gaps seams and cracks in your existing roof construction giving you even more protection. Your indoor air quality may get worse. Yeah you probably still breathed some of it but not as much as you will now with spray foam on the roof deck.
