Improper Ventilation

ventilationairflowVentilation is one of the most asked about topics here at Shew’s Top Quality Roofing and Guttering. With our Oklahoma Summer heat, homeowners are looking for ways to reduce summer cooling bills. And proper ventilation in the winter months is just as important. Attic Ventilation is a process of air intake and output. The flow of air is critical to promote good ventilation. As illustrated below, air movement is essential!


Below are just a few of the commonly used ventilation systems used by Shew’s Top Quality Roofing and Guttering in the Tulsa Metro and Green Country Areas.

whirlybirdThe “Whirlybird” is a good product for promoting air circulation. This ventilation system evacuates large volumes of air as it spins. The shape and design of this vent actually pulls air from the attic. There are moving parts and bearings in the Whirlybird, but it is fairly inexpensive and provides good ventilation.



Ridge vent – Installed at the peaks of the roof, this product allows for added efficiency at the highest point in the attic where hot air tends to become trapped. Ridge vent is popular because it is barely visible after installation, removes the hot, trapped air in the highest attic areas, has no moving parts, and gives the ridges of the roof a unique look.

Power VentPower roof mount attic ventilators feature a factory pre-wired combination automatic thermostat/humidistat. The thermostat/humidistat is in the same housing for an easy, single electric hookup. The thermostat monitors the attic for costly heat buildup in warmer months and the humidistat monitors the attic for damaging moisture buildup for year-round protection.

Power Vent undersideA power vent can move up to 1500 CFM, cooling attics up to 2100 square feet and requires at least 5.0 square feet of intake vents.



The Low Profile and Box vents are static roof vents.  That means they have no moving parts. Most homes have these vents.
