11 year old building in an old neighborhood. Roof pitch is probably on the order of 4 to 5 - 12. The house has a stucco finish on it, and the facia soffet stuff is basic press formed composite wood type material. soffet does have vents and all.

I know that I really need to get up there and see what kind of insulation is on the ducting itself, like def90 brought up.

I'd really rather avoid the gutter heaters because they're unsightly, cost money to buy, and install/have installed, and the cost of electricity to operate them...especially off a thermostat only. And who knows what any type of maintenance costs would be. And as you pointed out, Wulf, the insulation cost would still benefit me either way in the long run.

I just want to know what the correct fix is for my particular problem. Nobody likes pissing money away.....I don't.
