Hello, Lomanco Customer Support here & I'm cringing at the thought of covering the Whirlybirds!
We do not recommend covering your turbines!!! Properly functioning attic ventilation systems are required year around, especially in the winter! 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 and you.
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 damaging wood members and destroying shingles or it drips 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. Read Less

YES! When turbines are properly installed with a balanced system of intake and exhaust, they will not allow any weather infiltration.
Here is 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 Read More
Hello, Lomanco Customer Support here.
YES! When turbines are properly installed with a balanced system of intake and exhaust, they will not allow any weather infiltration.
Here is 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. Read Less

Answer: 
I asked the same question years ago. I have been told it is possible for rain to get in. But, it is very
unlikely, due to their design. With that said, one year with a very high wind, I think rain did get in, but
only once in 38 years. I cover mine in the winter now.

Hello, Lomanco Customer Support here.
Whirlybirds have undergone extensive testing to become Miami Dade County Approved as well as Texas Department of Insurance. The testing requires the Whirlybird to withstand winds of 110 MPH. These birds are tough and will not come apart.

Answer: 
anything is possible, but in 38 years I never had one come apart. What I do, after fasting the screws,
is wrap duct tape around it a couple of times, covering the connection.

Hello, Lomanco Customer Support here.
All of Lomanco’s products are designed to be on sloped roofs. However, some products can be adapted to be used on a flat roof if special precautions are made. A “curb” must be built up so that products can be adapted to work on a flat roof. The curb should be at least 4” off the flat roof.
Whirlybird turbines are a good solution for venting a flat roof if additional steps are made. The tall profile makes them a good option. You'll want to mount the turbine on a curb least 4” off the flat roof. You will also want to have the turbine flashing completely under the roofing material. Seal all seams, connections, exposed screws, and locking clamp holes with roofing cement.
The reasoning behind a pitch / slope requirement is for protection against weather infiltration. If the vent is on a flat roof and there is standing water, the concern is the water would submerge the vent. Hence the reasoning for the curb.

Rated 5.0 out of 5.0 by these work great and take the heat out of the attic they worked really well and were well worth the cost. September 6, 2016
Rated 5.0 out of 5.0 by Works as it is supposed to, but, expensive. Came quickly, box was not crushed. Pretty flimsy box though. Nothing was bent or damaged. Installed where wanted to and keeps workshop a good bit cooler. Atta boy for HD. August 2, 2016
Rated 5.0 out of 5.0 by It does the job well We seing this product before but never knew how good it works until we install in the garage roof and the difference its amazing August 16, 2016
Rated 4.0 out of 5.0 by It spins With a new roof why not put in a little more cooling. Easy installation June 28, 2016
Rated 5.0 out of 5.0 by well built I just replaced these turbines and left the existing foundations in place. In order for them to sit low enough I had to lower the screw holes, not that hard. These are built much better than my old ones. Spin nice. June 28, 2016
Rated 4.0 out of 5.0 by Good Product I think this is an excellent wind turbine for roof ventilation, in retrospect if you just barely need one 14" turbines, I believe having two of the 12" versions might be a better choice and more efficient at roof ventilation. June 7, 2016
Rated 5.0 out of 5.0 by Roof Turbine replacement Exactly as advertized and I believe going larger helps for venting. May 10, 2016
