To insulate or vent overhangs or not in conjunction with a non-vented attic?

ablondguy | Posted in GBA Pro Help on

If you are going to to have a non-vented attic area because of spray foam installation, would you insulate and/or vent any overhangs, i.e. in a hot and humid climate? This seems to be debatable amongst builders.

    There is no reason to install soffit vents if there are no ventilation channels for your attic or cathedral ceilings. If all of your roof assemblies are unvented, you don't need soffit vents.
