Spray foam insulation should be applied directly to the roof deck or rafters. (when installed in an attic)

Answer: False
Explanation: We come in behind homes every year that have had foam installed to the underside of the roof deck, usually leaving no insulation on the attic floor. This causes 2 issues: 1 it is very likely going to void any shingle warranty you may still have, sealing off your roof like that is not recommended as it needs to be able to breathe (hence the need for roof/attic ventilation). We see curling shingles very quickly after this kind of sealing is done. 2: not insulating your attic floor is causing you to now be heating & cooling your entire attic area as well as your home. You want to stop you heat/air loss at your ceiling (with proper attic insulation).
