Don't forget your hat. With increased insulation requirements in recent versions of the energy codes, continuous insulation on the roof can allow the owner to meet thermal insulation requirements in low- and steep-sloped roof applications with the following benefits: minimizes thermal bridging through roof framing, reduces energy losses through ductwork located in unvented conditioned attics, turns attics into living space or climate-controlled storage areas, and helps protect against moisture or condensation.
