Replacing an RV roof vent is not very difficult, but is a useful skill for an RV owner to have, given that roof vents wear down due to age and weather conditions. Plastic vents and other areas, such as the appliance cover and breather, end up thrusting outward. The sun’s harmful ultraviolet rays can wear down the vent so much that a small fallen branch can cause it to crumble. Hailstorms can also damage the rooftop regardless of the age of the vehicle.

Step 1 - Get New Cover

Take out a ladder high enough to reach the roof of the RV. You should be okay by yourself since this is not a very long climb, but if you prefer, have someone stabilize the ladder while you are on it. Once the ladder is properly positioned against the RV, climb to the roof to take off the old hinge cover.

Unless you have already bought a new hinge cover, take your old one to the store so you can get a new hinge cover that is compatible with your RV. You most likely won’t find the same brand, make, or model, so ask the salesperson to help you choose the right one. This may also be a good time to replace all your vents in either smoked or translucent material rather than the plastic material that is currently on the RV.

Step 2 - Install New Cover

Once you are home, get back onto the ladder and remove the pins from the hinge of the old vent. Straighten the tabs that go into the old vent, and then take off the lid. Next, straighten out the tabs that go into the new vent and then put the tabs into the new roof vent. Replace the hinges and check to make sure they are secure.

Step 3 - Protect New Cover

If you can, park your RV in a spot where there is shade or where the sun’s rays will not hit it directly.

You may want to purchase a MaxxAir cover to go over the entire vent. These covers are very strong and can tolerate most impacts. You still need to buy the replacement vent cover, but, with the MaxxAir cover, you can leave your roof vents open, even on rainy days. Leaving the roof vents open helps keep the inside at a lower temperature, which is good idea when the RV is not in use.

Also, ask about metal roof vent covers because they are impervious to hail and will last a long time.
