Common questions about attic & roof-deck insulation
Insulating the attic floor keeps the attic vented and hot but stops heat from reaching the living space below. Insulating the roof deck (an unvented, conditioned attic) brings the attic — and any ductwork in it — inside your home's conditioned envelope, which usually delivers the biggest efficiency gains in Arizona because your AC equipment stops sitting in a 140° oven. We recommend the right approach for your home after inspecting it.
Attic spray foam in the Tucson area typically runs roughly $1.50–$3.50+ per board foot installed, with most whole-attic residential projects between $3,000 and $8,000 depending on size and foam type.
