Hello, Lomanco Customer Support here.
No! When Lomanco Whirlybird's are properly installed with a balanced system of intake and exhaust, they will not allow any weather infiltration.

Hello, Lomanco Customer Support here.
No! When Lomanco Whirlybird's are properly installed with a balanced system of intake and exhaust, they will not allow any weather infiltration.
Here's why... The turbine has twenty-one (21) air-foil curved vanes with rolled edges to deflect water. The rolled edges are designed to force the water to run down the vanes & not into the attic. Air-foil means a body designed to provide a desired reaction force when in motion relative to the surrounding area. To summarize, the turbine should be turning at all times when there is outside air movement.
The centrifugal force of the turbine also prevents leakage. Centrifugal force is the force that tends to impel a thing or parts of a thing, such as rain, outward from a center of rotation, such as the bearing/shaft assembly in the turbine.
It is important that the unit be sealed with roofing cement around all seams, nails, and under the flashing. The part of the flashing that is facing the roof peak should be installed underneath the shingles and the bottom part should be overlapping the shingles. Sealing in this manner prevents water from entering the attic under the flashing.

Answer: 
You would think it would, but rain does NOT leak in. Of course, be sure the base is sealed where it meets the roof and do follow the instructions about sealing the joint for adjusting the tilt so it stands straight upright on your roof. The ventilator top is designed to not leak and mine does not. Besides the one I just installed, I have another on another shed in use for 13 years now. In those 13 years Read More

Hello, Lomanco Customer Support here - happy to help.
Attic ventilation systems are required year around, so we do not recommend blocking the turbine in the winter months. Most people associate attic ventilation with heat; however, of the two major destructive forces at work in your attic, moisture, not heat, is the most destructive. Since winter air is drier, it absorbs moisture from your home. The attic space is even more susceptible to excessive moisture in the winter. Plus when air is trapped inside the attic – it will always be warmer than the air outside. The roof sheathing/decking will be colder in winter months. Thus creating even more condensation. It can literally "rain" in your attic. This moisture produces mildew, rotting conditions that can damaging wood and destroy shingles, and can drip down to the ceiling below to damage plaster or paint. Insulation also becomes wet and provides less resistance to heat loss – in effect loses its R-value.
Keep your turbines spinning in the summer & winter months for a healthy attic. Read Less

Answer: 
Hi! It's customer support from Lomanco here. The Whirlybird's bearings permanently seal in lubricant to keep dirt and moisture out. These upper and lower ball bearings are the heart of the turbine and ensure long life and no maintenance.

Customer Reviews

Rated 4.3 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by Fine Product Ventilation powered by the wind. Mine is on a storage shed. Just follow the included instructions for installation. I like the black color as the black roofing tar - I tarred the joints outside the vent - doesn't show. Quiet and efficient. Besides venting the shed itself, the WhirlyBird also vents the flooded deep-cycle battery of the solar system for lighting the shed. July 26, 2016
Rated 5.0 out of 5.0 by Excelent Product This is what I had been looking for, with the critter guard. I looked at the turbines in the store and none had the guard. August 23, 2016
Rated 1.0 out of 5.0 by junk doesn't spin unless the wind is plowing, out of ballance June 22, 2016
Rated 5.0 out of 5.0 by Makes a difference! It definitely makes a big difference in the temperature of my attic, and therefore my house (I don't have much attic insulation). I highly recommend it. May 21, 2016
Rated 4.0 out of 5.0 by Easy Install However Installed really easy however I did not get any of hardware for mounting..... no screws or the locking clamp. That is why I only rated it 4 Stars. Just make sure when you buy it that it comes with the screws and locking clamp. Good thing I had some sheet metal screws, far as the clamp I used some thing I had laying around and made my own. Jury still out if it helps keep the house cool. September 23, 2013
Rated 5.0 out of 5.0 by Great cooling effect I already have three on my house. They really cool my house. The difference is very significant. I decided to put two in my garage because it gets really hot and it does not have any venting. So it gets too humid inside. I expect it will keep the garage cooler and dryer. For what it does, it is a great money saver. October 30, 2012
Rated 5.0 out of 5.0 by Be Cool & $ave Electricity. Saves juice and you don't have to wire it; how environmentally friendly can you get? June 26, 2010
