Powered & Solar Attic Fans

Attic heat builds up fast under a Florida roof, and a powered or solar attic fan gives that heat a way out. By pulling hot, moist air from the attic, these fans work alongside your existing ridge, soffit, and gable vents to ease the load on the roof deck and the insulation below it. SmithBuilt Roofing and Exteriors installs and services these fans as part of a broader look at how your attic breathes.

What We Check Before Installing

Existing Ventilation — A ventilation system evaluation confirms whether intake and exhaust are balanced before a fan is added.
Deck and Insulation Condition — Wood moisture meters check the decking around the attic for trapped moisture that a fan alone will not solve.
Placement — Chalk lines, levels, and layout tools confirm the fan sits at the right point on the slope before any cutting starts.

The Installation Itself

Clean Openings — Hole saws and vent cutting jigs cut a properly sized, clean opening so the flashing seals tight the first time.
Weathertight Flashing — Sheet metal brakes and hand seamers shape flashing to fit the specific roofing material around the fan housing.
Sealed Detail Work — Caulking guns and heat guns finish the seal around the base so it bonds rather than lifting later.

Where a fan alone will not solve the problem, attic insulation and air sealing, or additional ridge, soffit, and gable venting, can be addressed at the same time.
