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 500 CFM Solar-Powered Roof-Mount Exhaust Fan will help remove excess heat and moisture from your attic to protect your roofing system from premature deterioration. The Solar Powered fan requires no wiring, uses no electricity, and works with your existing intake vents to help lower the temperature in your attic.

Recommended usage for this unit is one unit per 800 sq. ft. of attic space with a minimum intake ventilation of 240 sq. in. of net free area.

Asked by Tony September 1, 2018

Answers

Yes, I would say it will definitely work for you. I say that because the installation you describe is EXACTLY my situation. My house is oriented with high gable ends facing due East on one end and due West on the other end. I installed this same exhaust fan on the North facing roof line, close to the crown of the roof, but not visible from the street on the South side. The small solar panel has an adjustment that lets you aim it straight up, but not quite enough adjustment to allow it to face in a southerly direction. Despite being mounted to that southern facing roof line, it irks great. A straight up orientation for the panel is not ideal at all, but it suffices to make mine run most of the day.

Are there any type of power indicators to let you know it’s running?

You can go outside and hear the fan working.

When installing the fan on the roof is there any possibility the fan can be put in backwards with the air flowing in?

Asked by Luke July 18, 2018

Answers

With some bracket modifications you could do that. Just need panel to have direct sunlight hitting it.

How long does it take after installation until you start to feel a difference in the indoor temperature?

Asked by Luke July 18, 2018

It starts working immediately. If you install in morning your attic will be cooler that day.

This product uses a heavy duty screening system.

can I install thermostat if is yes which would you recommend

Asked by Mark July 8, 2018
2
Answers

I would imagine you can, but why would you do it? When the sun comes up and the heating starts to heat the attic, the fan comes on automatically. When the sun goes down the fan stops. Thus, you have an automatic thermostat. Good luck.

will it still go on in winter months ..taking wark air out ?

Asked by Rick June 23, 2018

This will still operate as long as there is direct sunlight on the panel. If you have any other inquiries about our Master Flow products please call Technical Services at 800-211-9612.

I had my attic air sealed and insulated and the contractor suggested I buy this model. The fan is very quiet and it runs fine in the midwest on the south side of Chicago. Yes, we get cloudy days but I had this installed in March and it has already tremendously helped. I recommend this product. I was even thinking about putting one in my garage roof but I read that one customer had problems with his garage door opener afterwards.

Very great product when the roofline is a hipped out roof with a very short ridge line and you have a good part of the back of the roof with either southern or western sky exposure.

Great product! Good Value!
I purchase 2 of these units when I put a new roof on the house. We noticed an improvement the upstairs temperature almost immediately after installing. I expect to see a return on my investment in reduced AC costs. I highly recommend.

These solar powered attic fans are absolutely awesome. My only regret is that I only installed one. Since my ceiling isn’t drywalled yet, I have been able to watch this thing work every day. I will install more of these on my next build. New build, remodel or re-roof.I highly recommend this product

I actually mounted this on the roof of my RV to help keep the temperature down. I've only recently installed it, but so far I'm very pleased. The fan is very quiet and I was concerned about that. It only works when the sun is fully out of the clouds, but that's okay. Good choice.
