Questions & Answers

Does water get through the vent when it rains?

Asked by: Sho
Depends... If the rain/water is a huge downpour there might be water that comes through the slots of the vent. Many people during the winter or rainy season will cover them with small hoods which will stop the water from coming through. It shouldn't come through at the base if mounted correctly.

can rain go through this into insulation ?

can rain go through this into insulation ?
Asked by: BobA
No. It is always possible, but the more wind driven the rain, the faster the vanes turn, thereby preventing even horizontal rain from entering the structure.

how do you adjust for pitched roofs

how do you adjust for pitched roofs
Asked by: cowboy
Hello, Gennifer from Lomanco here. To determine roof pitch, place pitch gauge on peak of roof. Position straight edge as shown on instruction sheet (comes in box with turbine or you can find this online on our website www.lomanco.com). Read roof pitch from printed gauge parallel to bottom of straight edge. Align roof pitch number on elbow with the indicator line on the base flashing. If you have any additional questions, feel free to call and speak to customer service at 1-800-643-5596.

Is there any negative consequences if this are installed in addition to the existing vents ?

Asked by: Abel
There shouldn't be if they are the same or stationary type that let air flow out; it should just add to the exiting of hotter air...But if you have a motorized vent/fan set up which pushes air out of your attic then the air could flow backwards into the attic instead of out, which would defeat the purpose of this type of fan.

Rated 5 out of 5 by from We've had this installed for about a month. So far so great. Compare with a Turbine Aire WTI12X... We've had this installed for about a month. So far so great. Compare with a Turbine Aire WTI12X 12-in turbine vent that we picked up from Lowes in town. Summer time, Albuquerque. Maybe it was just the heat, but that model from Lowes stopped spinning freely in about a day (nothing against Lowes, they're fine too, it's just the truth). We tried another of the same model that stopped spinning freely also in about a day. We purchased this 12-in Whirlybird online from Home Depot and it installed right on the same flange base (not recommended but a quick test), and has been spinning freely ever since - a very clear improvement. It would be more ideal if could install the flange base that came with this Whirlybird as it is sturdier and would fit better. Anyway, this Whirlybird was a little more expensive but worth it. The aluminum thickness of this product is also greater and overall construction sturdier. Photo shows the old flange base with the new turbine on top.

Rated 5 out of 5 by from Great warranty I have had 3 of these since 1979 and the top bearing started going out on all three of them so I called the company and they are going to send me three new ones. They are easy to replace as well. The top part has three screws that hold them onto the base part that is attached to the roof.
