Product Overview
Nothing protects quite like a roof.
Nothing protects quite like a roof. That's why millions of Americans live, work, and play under quality products from North America's largest roofing manufacturer - GAF.
How much Ventilation do I need?
Include 1 sq. ft. of attic ventilation, evenly split between intake and exhaust, for every 300 sq. ft. of attic floor space.
What type of Ventilation do I need?
Review the ventilation options below to determine the best fit for your home application.
High efficiency Electric, Solar or Hybrid
Quickly removes large volumes of heat and moisture from your attic.
No electricity required
Allows excess heat and moisture to escape your attic without the need for electric hook-up.
Wind-powered, smooth, and quiet operation
Utilizes the wind to pull heat and moisture from attic; acts as a static exhaust vent when wind is still.
The most overlooked and critical part of attic ventilation
Allows cooler, fresh air to enter the attic at/near the soffits driving heat and moisture out higher exhaust vents.
5 Warning Signs
Here are some poor attic ventilation warning signs that you may recognize:
1. Increased energy costs
Excess attic heat can cause your cooling system to work harder, raising your energy costs.
2. Curling/cracking shingles
Inadequate ventilation can cause your roof shingles to curl and crack.
3. Roof decking moisture
Excess attic moisture can drip into attic insulation reducing effectiveness, even damaging ceilings below.
4. Attic mold/mildew
Excessive moisture can cause dangerous mold and mildew causing additional concerns.
5. Winter ice dams
Ice dams can cause expensive leaks and damage in attics, as well as living spaces.

Questions & Answers
Can I put this on an on/off switch instead of a thermostat?
Asked by ARSN1 March 31, 2021I left the thermostat connected on the 3 units I installed on my house and garage roofs and installed a switch in an electrical box supplying power to each individual unit. This allows both options for each unit.
Do they come with wire mesh to keep out rodents
Asked by Al December 4, 2020Yes its a good quality metal mash, it will last for many years great product.
Can I speed control be added?
Asked by Rich November 24, 2020No, this is a single sped motor, adding a speed control voids the warranty and may harm the fan. If you have any other inquiries about our Master Flow products please call Technical Services at 800-211-9612.
just installed.. live in Michigan temp is 45 degrees... will this work right away in cold temps
Asked by pearljam October 30, 2020if you installed the in-line thermostat probably not. check the setting on it, it can be adjusted with a flat head screwdriver. if it's not running even at the minimum temp setting then it's most likely because it's not rated to run the fan at that low of a temperature. if you need to operate at a lower temp, remove the thermostat and wire it to a switch. then you can operate it manually.
