Is it possible to install a Ridge Vent wrongly?

The attic can become a breeding ground for mold if it is allowed to remain in the air for too long. The beam of your roof will also begin to rot. To let warm air out, it is important to install the vent correctly.

How does the inside of a Ridge Vent look?

Your house's roof will determine how your ridge vent appears from the inside. Some houses have a metal roof installed directly on top of the roofing boards. This roofing method is used to vent the attic. You will notice a small hole in the roof's underside if this is the case. This space can be viewed to reveal the underside vent at the ridge.


Some houses have different roof designs. You might not be able to see the underside of your ridge vent if the roofing contractor left enough space between the metal roofing boards and the boards.

Warning Signs that your Ridge Vent has not been installed correctly.

It is important to identify a faulty ridge vent as soon as possible. You can usually fix most roof ridge vent problems quickly or contact a professional shield roofing company before damage occurs. You should still be aware of the warning signs that ridge vents may have been improperly installed so you can take corrective action.

Ridge Vent Leaks

If water is leaking from your ridge vents, it is an indication that the vents are not properly installed. If water is leaking through the vents, it means that seams or fasteners have become loose and the ridge vent is disconnected from the roof. You may see water trickling in some cases if there are bowls or sealant defects on the roof.


Remember that roof leaks near the ridge vent are not always due to the caps. It's almost always due to the way the vent was installed. You can inspect your roof by taking a walk along the length of the ridge vent. Then, pull the vent slightly to check if it is in place.

No air entering the soffit vents or out the ridge vents

If you don't see any air coming out of the ridge vents or soffit vents, it is another sign that the vent isn't installed correctly. If you observe your ridge vent at a distance on warm or cold days, you can tell if it is. The ridge vents are functioning well if you can see the blurring of air leaving the vents during warm weather. If they don't work, that's a sign they haven't been installed correctly.

Shingle Obstructions

Shingle obstruction is a common problem with ridge vent installation. To avoid any shingle obstructions, your roofing contractor must be careful during installation.


You are not allowed to view the underside of the roof when inspecting the ridge vent from inside your attic. This is a sign that there may be a serious problem and you need to investigate it immediately. Most often, the roofing contractor may have left the ridge vent longer than it should have.


It can be difficult to deal with shingle obstructions. Your  roofing contractor should use proven techniques to resolve the problem. You should not cut the extending roof shingles off the roof's top because it can cause leakage.

Roofing Felt Obstructions

Your ridge vent can be blocked by roofing felt. This happens when your technician applies felt of paper to the area where plywood was removed before installing the ridge vent. If this is the situation, the felt of construction paper will block your ridge vent. This obstruction can interfere with the performance and efficiency of the ridge vent.


This error can be detected by inspecting the ridge vent from inside the attic. To examine the mesh under the ridge vent mesh, you will need to remove the building paper. This problem can be solved by a certified roofing technician.

Attic Leakages

One of the most obvious signs that a ridge vent is not properly installed is leakage in your attic. If there is not enough space for moisture to flow through the ridge vent, leakages can occur. Precipitation is what gives rise to moisture.


Because of the effect they have on your roof, attic leakages can be easy to spot. Water droplets that fall into your attic can cause wooden structures to rot. Attic leakages can also cause mold growth. Routine roof inspections can easily detect these signs. Your roofer may not have used enough sealant when installing the Ridge Vent.


Incorrect installation of ridge vents could lead to costly repairs. There are many things to consider, including leakages in your attic, roof rot, or ridge vents being blown away by strong winds. Follow the manufacturer's instructions when installing your ridge vents. You can also hire a certified roofing technician for the job.
