How to determine whether you need better attic ventilation
- Look at your eaves and roof.
- Touch your ceiling on a warm, sunny day.
- Thick ridges of ice on your eaves in winter are a sign of poor attic ventilation.
- Warm air that escapes living space also carries moisture that will condense on rafters or roof sheathing.
How do you test a roof vent?
Use a flashlight to shine a bright light down the vent pipe to look for further blockage you can reach. If you can see but can’t reach, run a plumber’s snake down the vent pipe. To continue, feed the end of a garden hose down the vent and have someone on the ground turn on the water.
Are gable vent fans Effective?
Even if your roof already has ridge vents and plenty of ventilation built in, it’s a good idea to install gable fans or roof fans to help blow hot, humid air out of the attic. Attic ventilation fans also tend to be quite energy-efficient in terms of their own operation.
How do I test my soffit vents?
There are two easy ways to check this. If you can get into the attic when it’s dark (or bring a flashlight but then turn off the attic lights), see if you see light when looking into the eaves – if so there were openings cut. If not there were either no openings or they are blocked.

Should gable vents be closed in winter?
You should absolutely leave your roof vents open during the winter – do not cover them! During the winter, roof ventilation works to keep temperatures even. Closing your vents makes the attic space too warm and dry – dangerous conditions for mold as well as pests.
Should I block gable vents?
There is no need to block the gable vents unless they are prone to collecting windblown rain and snow. (This would not be related to adding the ridge vent; that would have already been true before the roof work.)
Should gable vents be closed?
If windblown rain or snow is frequently entering the gable vents, close them. Don’t worry about an airtight seal; just nail a board over the opening from the inside. To summarize: Seal air leaks in your attic floor so that roof venting doesn’t suck conditioned air into the attic and cause moisture problems.
Are gable vents reliable for roof ventilation?
Pro: Gable vents are generally quite reliable when it comes to keeping your roof cool and also quite low maintenance when being compared to other motorized ventilation systems. When being compared to a rooftop attic fan, for example, that is prone to rust, bearing wear and tear and rodents getting in and damaging wires.
Should I attach a gable vent fan to my roof?
Attaching a gable vent fan pushing air inside your attic or roof out will assist in keeping the humidity and overall heat down. There is a downside to using them though, and that is you are now using energy that you could otherwise be saving if you just had decent air circulation in your roof.
How do you measure for a new gable vent?
Step 1 First off you want to start by using the template that came with your new gable vent to mark the size of the vent on the inside of your wall. If you new vent did not come with this template, use the vent itself instead. Hold it steady against the wall and mark off the area you need carefully.
Can I use my gable vents to cool my attic?
The plain and simple answer is yes. Just relying on your gable vents to cool your attic is a big ask, as this will only work optimally when you have a cross breeze blowing towards one side of your roof, blowing the hot air out the other side.
