Product Overview

More homes and businesses in the U.S. are protected by a GAF roof than by any other product. We are the leading roofing manufacturer in North America.

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.

Always have a balanced ventilation system. The amount of exhaust ventilation should always be equal the amount of intake ventilation.

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.

Choosing the right attic ventilation for your home is very important. GAF offers a great selection of Master Flow and Cobra products.

What type of Ventilation do I need?

Review the ventilation options below to determine the best fit for your home application.

Available in both roof mount and gable mount, power attic vents exhaust the greatest volume of hot and/or humid air from the attic.

High efficiency Electric, Solar or Hybrid

Quickly removes large volumes of heat and moisture from your attic.

Cooler external air enters through vents lower on the eaves or soffits that “pushes” the hot/moist attic air out of the vents higher on the roof.

No electricity required

Allows excess heat and moisture to escape your attic without the need for electric hook-up.

Wind Turbines utilize the wind to pull heat and moisture from your attic and acts as a static exhaust vent when wind is still.

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.

Located at the lowest part of the roof, intake vents are a critical part of the attic ventilation system, allowing fresh air to flow into the attic

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.

Your home offers warning signs when your attic isn’t properly ventilated. You may recognize some of these signs in your own home.

5 Warning Signs

Here are some poor attic ventilation warning signs that you may recognize:

A possible cause of higher cooling costs could be insufficient attic ventilation, requiring the cooling system to run excessively.

1. Increased energy costs

Excess attic heat can cause your cooling system to work harder, raising your energy costs.

If you see that your shingles are dry or breaking, that could mean you have inadequate attic ventilation or you may need a new roof

2. Curling/cracking shingles

Inadequate ventilation can cause your roof shingles to curl and crack.

Moisture in the attic can become trapped and condense on rafters and insulation if not insulated properly. This can potentially increase energy costs

3. Roof decking moisture

Excess attic moisture can drip into attic insulation reducing effectiveness, even damaging ceilings below.

Stains or mold growth inside your home may be caused by inadequate attic ventilation. Excessive moisture in the attic allows mold and mildew to thrive

4. Attic mold/mildew

Excessive moisture can cause dangerous mold and mildew causing additional concerns.

Ice damming can cause water to enter the attic and house if you don’t have an adequate shingle underlayment or if the flashing has deteriorated.

5. Winter ice dams

Ice dams can cause expensive leaks and damage in attics, as well as living spaces.

The GAF Master Flow EGV5 Gable Mount Attic Ventilators are a great choice for exhaust ventilation. They are typically easier to install and won't detract from the appearance of your roof. They can quickly remove a larger volume of hot and/or humid air from your attic, compared to static ventilation, which helps save money on your heating and cooling costs. The EGV5, Power Gable Mount Vent can move air at a rate of up to 1450 cu. ft. per minute. For attic spaces up to 2300 sq. ft.
  • Mounting brackets included for installation
  • Helps to reduce energy costs and helps prolong life of the roof and shingles
  • Galvanized steel construction for durability
  • Mounts in the gable inside the attic
  • Optional humidistat available (H1) - sold separately

You will only hear it when you are within a few feet of it in the attic.

I purchased this exact fan for the gable vent back in 2017 during a renovation. We also have the furnace in the attic, about 35/40 feet from the gable fan, and have never had a problem with it extinguishing the pilot. If you have dormer/soffit vents in addition to the gable vents, you should have enough outside air coming in to not create a huge vacuum when this fan turns on. Also, all modern gas appliances with pilot lights have a fail-safe device that closes off the gas to the appliance in the case when the pilot may go out- including furnaces. Hope this helps!

Yes of course it can but I would go with a solar powered type instead as that fan is to much for a small space as a storage shed as that's what I will do with my storage shed

Worked well for 6 years.
Replace old fan this unit in about 2014. (2200 sq.ft. attic) Noticed this summer wasn't working. Froze up. Probably worn bearing. Good calculation providing the 5 yr warranty. Going to buy another one just like it, nevertheless, because it will be easier to throw the new one into the existing drum.

Great fan at a great price. So Far, so good!
Replaced an old fan that went bad. I used my old brackets but everything else worked good. I used rubber grommets from the hardware store on the 4 brackets to hush any vibrations that might be created. Quiet and efficient. Left the factory setting at 115 degrees. My fan comes on for an hour or two then shuts off for a bit. 85 degrees and humid weather. Very happy so far!

nice little upgrade
In order for this fan to be effective, you need to properly install it and when I say properly, I mean not to place on a couple of 2x4s... so, measure your gable, grab a 4x8 sheet of half inch plywood and make a shroud out of it. Without it, all this fan is gonna do bounce the air all around it. Try to guess why car radiator fans are shrouded...

Purchased this to replace a 25 year old gable attic fan I purchased at Home Depot years ago that finally failed. That was a 4 blade fan and was quite noisy. This replacement is 3 blade and much quieter. The thermostat on the old fan also developed a problem where when the temp dropped to turn off it would, but then after 30 seconds or so would turn the fan back on. This sequence might continue for another 5 minutes until the attic temp was a few degrees lower to keep it completely turned off. The new thermostat works perfectly. Once the turnoff temperature is reached, it stays off. The photo is of the new unit installed. Years ago when I installed the first fan, I had built a wafer board box over the gable vent to ensure all of the fan air was pushed out. The replacement fan had to have the same diameter as the cutout for the original fan, and this did. The mounting holes were in a different location though, but this was a minor issue as I just drilled the screws in to the wafer board for the new locations, then plugged up the old screw holes with a little caulk. I would have given the unit 5 stars if it had not come with a "capacitor" start motor. I have electrical engineering friends and they tell me the capacitor is most prone to failure. If you look at the left side of the motor in the photo, you can see the black block with the light colored label on it. That is the capacitor. My original fan was NOT a capacitor start motor and it lasted 25 years. It will be interesting to see how long this motor lasts. And one thing I would like to see the manufacturer do; put rubber vibration isolation grommets on the motor arms where they attach to the air duct. Also include vibration isolation strips of foam for the installation to go between the mounting tabs and the boards the fan is to be mounted to. Although the unit is quiet, not totally. This would hopefully make it so. Last, make sure the motor mounting arm screws are fully tightened to the air duct. 2 of mine were not. If I did not check this to securely tighten them, then I would have definately had vibration noise.

Easy to assemble, easy to wire, and easy to mount. Plenty of output to suite my needs. I used this particular fan to construct a shed for my generator to handle the exhaust gases and fumes. Love it because the actual motor is replaceable although I doubt that I'll ever have to replace it.

I chose this vent fan more for it's energy saving motor over a cheaper unit. Seems to be made well, no vibration while running and much quieter than the one it replaced. GAF has a five year warranty on it so I hope it lasts a few more years than that. Thermostat seems fairly accurate too.

I purchased this to help bring down the temperature in my attic space in the hopes that my AC unit would function more efficiently. I installed the fan in the gable roof and experimented with the thermostat setting a bit. Although it is factory set to 105F, I found that a setting of 90F worked best to keep the air in the attic cool. So far, the attic has not exceeded 10F above the outside air temperature and the upstairs AC is working really well now (no more complaints from the kids about their rooms being too warm!) The biggest challenge was finding the right size gable vent to go with the fan. Many of the plastic gable vents either had smaller openings than needed for the fan or did not include any type of screening to prevent "critters" from entering. I finally found the Ekena Millwork 21 in. x 29 in. Smooth Western Red Cedar Functional Gable Vent with Flat Trim Unfinished (Model # GVWVE16X2401SFUWR Internet #300033551). The rectangular shape of this vent made framing for the fan installation much easier. I painted the vent to match my home and am very pleased with how it works with the fan. The included critter screen was exactly what I needed! One note: Since taking the install pictures, I've added some additional pieces of wood to cover the difference between the circle of the fan and the square frame to insure all the air is pushed out of the attic. The RED areas in the picture show how these pieces of wood were cut and installed. I highly recommend this set up to anyone looking to reduce their attic space temperature.
