A solar-powered fan that pulls hot, damp air out of your attic, with no wiring and nothing added to your electric bill.
A solar attic fan is an exhaust fan mounted on the roof or a gable that runs on its own small solar panel. When the sun is out, the fan pulls hot air out of the attic and draws cooler outside air in through the soffit vents. Home Crew Construction installs solar attic fans on homes across Long Island, in Nassau County and Suffolk County.
On a sunny summer afternoon, an attic with poor airflow can get far hotter than the air outside. That heat soaks into the shingles from below and into the ceilings of the rooms underneath. A solar fan is one of the simplest ways to move it out, as long as it’s sized and placed to suit the rest of the attic.
A solar attic fan is worth it when an attic runs hot or damp and passive vents can’t keep up. It runs on sunlight, needs no wiring, and exhausts the heat and moisture that wear out shingles. Home Crew Construction installs solar attic fans on Long Island homes as part of a balanced ventilation system.
How it works
A roof is a system of layers, not just shingles. Each one has a job, and a leak usually means one of them has failed.
The solar panel powers the fan directly, so there’s no wiring to run and nothing added to your electric bill. The fan works hardest on sunny days, which is exactly when the attic heats up most. It’s still part of the attic’s ventilation system: it needs enough intake at the soffits to pull air from, or it will draw air up from the house instead.

A solar attic fan is a good fit when:
It isn’t always the answer. If the soffits are blocked with insulation, or the roof already has a ridge vent, adding a fan can upset the balance of the system. That’s why we look at the whole attic before recommending one. Sometimes the right fix is simply better intake.
Both move hot air out of the attic, in different ways. A ridge vent is passive: it runs the full length of the peak and relies on warm air rising, with no moving parts. A solar attic fan is active: it pulls air out on sunny days, when the attic is hottest, which helps on roofs with a short ridge, hips, or an attic that stays hot even with passive vents. They don’t usually belong on the same section of roof, because the fan can pull air in through the ridge vent instead of the soffits. We’ll recommend one or the other based on your roof’s shape and what the attic needs.

Replacing your roof soon? Adding a solar attic fan during a roof replacement is simple, since the roof is already open and the ventilation is being planned anyway. If you’re not sure what your attic needs, a roof inspection is a good place to start.

Solar attic fans FAQ
Still not sure?
Call 631-965-0881 any time. We'll tell you straight whether it's a repair or a replacement.
It slows down or stops when there isn’t enough sun. That’s usually fine, because the attic heats up far less on cloudy days. The fan does most of its work when the sun is strongest.
No. The fan runs on its own solar panel, so there’s no wiring to the house and nothing added to your electric bill.
Often it shouldn’t be. A powered fan can pull air in through the ridge vent instead of the soffits, which short-circuits the airflow. We check your existing vents before recommending one.
Not when it’s flashed in properly with the shingles. We install the fan so the flashing sheds water the same way the rest of the roof does.
