How do I best insulate a house without an attic?
I have been researching the last six months what to do about our roof that needs replacing. We live in the Sacramento Valley, hot days and cool evenings (usually). Our house was built in 1966 and is adobe brick.
We have cathedral vaulted ceilings throughout the entire one story house – mostly NO ATTIC. Our current roof configuration is this: Tounge/groove ceiling, 1/2″ ply, 2″ Polyiso (Celotex Thermax) with reflective foil covering both sides, another 1/2″ ply, felt and finally comp shingle. We have no existing grid or frame system OR venting system. We bake in the summer and freeze in the winter.
A small section of our hallway has some attic space – so we added a whole house fan earlier this year.
Looked into building up the roof with 2x6s and then adding 5" of closed cell spray foam but that is cost prohibitive for us. Any other ideas?
