If you don't have HVAC and ducts in the attic, spray foam on the roofline isn't really necessary. I'd blow insulation on the attic floor (after air-sealing, of course). The big disadvantage with spray foam is cost. It's generally 3 to 4 times what you'll pay for blown cellulose or fiberglass.Sep 27, 2011
