A: Hello, Gennifer from Lomanco here. Our turbines are adjustable for a 2/12 roof pitch up to a 12/12 roof pitch. If you have any additional questions, feel free to call and speak to Customer Service at 1-800-643-5596.
A: Hello, Gennifer from Lomanco here. A well vented attic with turbines will drop attic temperature 15-20 degrees. We have specific metal roof installation instructions on our website at www.lomanco.com. These instructions are for standing seam metal roofs or rolled profile metal roofs. The 14" Big Whirly moves up to 37% more air than the 12". The air being exhausted through the turbine MUST be replaced by outside air drawn in through intake vents located near the lower part of the attic space to properly ventilate the total attic area and eliminate weather infiltration. Lack of intake vents results in extreme heat buildup in the summer and severe moisture problems in the winter. You must have a continuous supply of fresh air to “feed” the exhaust vents.The intake system must provide as much or more than the exhaust system in net free area. Each 14” turbine requires 345 square inches of intake ventilation. If you have any additional questions, feel free to call and speak to customer service at 1-800-643-5596.
A: Hello, Gennifer from Lomanco here. Yes, our turbines turn on American-made polymer ball bearings for silent operation and no maintenance. Each turbine is factory tested to turn in a breeze of less than two miles per hour. If you have any additional questions, feel free to call and speak to customer service at 1-800-643-5596.
A: Hello, Gennifer from Lomanco here. There are a few things to consider regarding the just-installed Whirlybird turbine and why it may not be spinning. First, for hot air to exhaust through the turbine there must be adequate intake air provided to the attic area via intake vents located lower in the attic space. If there is not enough intake air, this may be restricting the amount of air exiting through the turbine. Second, the bearings are lubricated with grease and it may take a few weeks for the bearing to "break in". It is likely that within a few weeks, the turbine will turn freely. For optimal operation, the turbine should be installed level to the ground. The turbine head may have shifted slightly during transportation and minor adjustments may need to be made. The top can be adjusted by using a flat head screwdriver to pry the lowest point of the turbine upward. If the base is not level, it may be necessary to make some adjustments. The pitch setting may need to be changed. The base (elbow) may be made level by adjusting the pitch to a different setting. The bottom of the elbow will turn clockwise (the elbow will move along the "seam") to align roof pitch number with the indicator line on the flashing. If you have any additional questions, feel free to call and speak to customer service at 1-800-643-5596.
