Your roof works harder than you think.

Unventilated attics run hot in summer and trap moisture in winter — both age a roof faster than it should. A solar powered vent moves air all day, every day, without relying on wind or a temperature gradient the way passive vents do.

Attic heat can climb well past 130°F (55°C) on an unventilated roof, baking shingles from underneath and pushing warm air into the living space below. Moving that heat out protects the shingles and takes load off the A/C.

Warm household air rising into a cold attic condenses — left unchecked, that moisture rots roof decking, feeds mould and, in freeze/thaw cycles, contributes to ice damming. Keeping the attic ventilated keeps it dry.

No — they're silent from ground level. Up close, all you'd hear is air moving through the housing.

Yes to both. The housing is an ABS/polycarbonate blend that's very difficult to chew or tear through, and the solar panel is tempered-glass covered.

No battery — the panel drives the fan directly (a direct-current system) while there's usable light. At night the vent sits passive; there's no on/off switch to operate.

Yes — the panel runs on UV, not direct sun, so it keeps working (just not at full speed) on overcast days.

No. The unit has no house wiring to tie into, so any roofing contractor can install it. Prefer someone who already knows the product? Use the installer finder above.

10-year limited warranty against product defects — register online after install to activate coverage. If a component fails, the recommended fix is replacing the unit rather than individual parts.
