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 ERV6 Power Roof Vent is a great overall investment in attic ventilation. It can efficiently remove a larger volume of hot and/or humid air from your attic when compared to static ventilation. This in turn can help save money on your heating and cooling costs. The ERV6 model Power Roof Mount Vent can move air at a rate of up to 1500 cu. ft. per minute. It is designed for attic spaces up to 2800 sq. ft.

Can I speed control be added?

Asked by Rich November 24, 2020
2
Answers

Mike here again, Did you consider using an in the wall Timer instead of a Speed Control. The motor is a "single speed motor" so like I explained before you are lowering the voltage to it to get it to slow down. Not the proper way to do it but Yes it can be done that way and it will shorten the life of the Exhaust Fan. Now a Timer is a totally different beast. It's basically an ON and OFF switch that you don't have to monitor or if you want to then get an Alexa Wall switch and Control you Fan that way.

just installed.. live in Michigan temp is 45 degrees... will this work right away in cold temps

Answers

if 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.

Asked by JackMC August 4, 2020

Never checked on warranty. I usually have to replace an electric fan motor about every 3 years. I set the temp to start fan at 110 degrees.

Can I use a smart dimmer switch with this? Dimmer is 600 watts.

Asked by Kam June 25, 2020
2
Answers

No, a dimmer is the wrong controller. You would need a fan speed controller if you are trying to limit the volume of air flow. If you are just wanting to be able to turn it on and off I would suggest a regular smart switch.

I've purchased Many of the GAF Master Flow power vents and several years ago I purchased them because the motor had lifetime warranty but I noticed on this one it's only a five year warranty so they're easy to install and simple to put Power to but I can't say how long it's going to last or its durability because it's only been installed for one week. If you have a difficult home to ventilate and you need positive airflow I highly recommend installing a power vent. They definitely remove heat for a minimal amount of cost. As a professional roofer of 30 years when the home has ventilation issues that ridge vent can't solve powered vents do the job. Solar Vents do work but they are subject to the Sun. In Texas it can be a hundred degrees and a cloudy day that solar vent will barely move.

The product was easy to mount and wire. At first, it seemed that it wasn't working but when I adjusted the thermostat a bit lower, it did kick on and run as described. It moves a lot of heat and humidity out of a big attic space. In my case, the hole in the roof from a previous turnstile stack exhaust was a little bit too small but gave me a starting point to use a reciprocating saw and make a larger hole in the roof surface, this was surely the most difficult part. I used elastomeric waterproofing to seal it after installation, then further coated the area with elastomeric white roof paint. Two storms later, still dry.

Easy installation, I watched a couple of youtube videos before doing the installation myself, and it was really easy. This product has worked for me so far, I installed it about a month ago and it has helped reduced the heat in my house. As far as lowering the electricity bill by reducing the amount of time the A/C is running, that is hard to tell because this last month has been hot, hot, Texas hot.

I have not had it fully installed (the electrical has not been done yet), but one of the fans was delivered badly dented. There was already a hole int he roof, and I couldn't wait another week or more for a replacement, so the handyman pounded out the dent so that the unit will function. Not happy about that!

I'm very pleased with this fan, it is very inexpensive and powerful at the same time. Before installation I've learned to tighten the 4 bolts on the top of the hood before installation, for some reason they come loose from the factory and I did not know this until I had a client call me complaining about the fan making noise just 5 days after installation. Other than that, Great Product.
