Code On Insulated Roof Systems And Attic Space


Location-Austin, TX

Working on a NC warranty punch list on an upscale condo near 6th St in Austin. It has an insulated roof system (standing seam metal roof).

Are there any venting requirements for a conditioned attic? Is that the proper term?

Re: Code On Insulated Roof Systems And Attic Space

No venting at all. It defeats the purpose of the space.

Most often any "conditioning" of the space is latent transfer through the ceiling.

Re: Code On Insulated Roof Systems And Attic Space


yes the roof is the only part that is insulated. there are no vents supplying air to the attic space.

should the joists have spray foam applied as well? I don't work on many newer high end houses, but the last one had the roof and ceiling floor foamed. that was the Jackson job-no expense spared.

thx Tom, I suspected so. The 'home inspector' called out that it needs ridge and soffit venting which didn't add up. in general all of his inspection items have been on target.

I’ve never seen the ceiling joists sprayed.

In your climate, from what I can tell from the picture, as long as there are no vents the installation is correct.

You may have to put a supply vent up there, but NO other venting per the codes
No you would not spray the floor joists
You have a "hot roof" or what others sometimes call an encapsulated attic

the hvac does have a fresh air supply system that's tied into the air handler's return plenum. it has a controller that is set to a certain number of minutes of air/hour.

thx guys (y)

Yeah. Hot roof. You could put unfaced batt insulation in the ceiling joists...
