Roof turbine
(OP)
I am considering installing 1 or more roof turbines to cool my house attic (quite hot in N. Tex). Anyone have experience with them? That is, are they really effective & save on cooling costs? Approx 2000 sf roof area, DFW area.

A foot of insulation helps a lot more.

Attic spaces get into the 100's easily, and all that heat will conduct into your occupied space contributing to the cooling load.

If you decide to add more turbine vents to your roof, be sure to buy ones that are aluminum. These will not rust. In addition, pay attention to the maximum roof pitch that will work with the turbines. The turbines are adjustable so that the spinning part is level even though the roof is slanted. Not all turbines will fit all roof pitches. The maximum roof pitch is almost always printed on the box label. Finally, be sure the ball bearings are permanently lubricated and sealed. Nothing is more bothersome in the middle of a windy night than a squeaky roof turbine!
