RV Roof Vents

If you own a RV there’s a very good chance that you have one or more roof vents. RV roof V2092SP-28_500vents are installed in order for the RV’er to let fresh air in their unit. These vents are made up of a shroud, frame, screen, crank assembly, and lid. When the original vent was installed in the RV the entire vent (frame, screen, crank & lid assembly) was placed from above through a 14 X 14 hole in the RV roof and the shroud is installed from inside the RV for cosmetic purposes. The vent is then sealed from the roof with RV roof sealant.

Unfortunately vent lids are very susceptible to weather damage. It is very common for Vent lidsRV’ers to find that their vent lids have deteriorated due to prolonged sun exposure or have encountered a bad storm. Other ways that vent lids break are from either shoveling snow in the winter or contact with trees or other obstacles.

When a vent breaks it is usually just the lid that is damaged. This is a very good thing because unlike replacing the entire vent; the lid is very easily replaced. All you need to know is what hinge pattern you have and installing a new lid is simple.


If by chance the screen and lifting mechanism of the vent lid is damaged replacement becomes a much bigger process. First,l the caulking covering the base of the vent and the RV roof needs to be completely scraped off and cleaned. Then the vent needs to be removed and putty needs to be placed under the new vent flange. The inside shroud should be unscrewed and removed at this time for ease of installation for the vent above. The new vent is now ready to be placed in the roof and screwed down. After the vent is screwed into the roof, the screws and edges of the vent must be sealed with a specific RV roof sealant. Now that the roof is sealed, the shroud inside needs to be reinstalled or replaced (most roof vents come with a replacement shroud; however depending on the thickness of the RV roof you may need to purchase a thicker or thinner shroud).

Because I’m a proactive person I’ll let you in on a little secret…there are ways to make sure that your roof vent never breaks! Vent Covers.

If you install a vent cover over top of the existing vent, it will be protected from almost everything that can destroy your existing vent lid while still allowing sun light and air to come into the unit. Most of these vent lids have a zero-leak design so that you can just drill holes into the side of your existing vent surround and never have to remove caulking or anything else to install them. The picture below is of a Maxx-Air vent lid cover that features;

  • Rain or Shine! Stale Musty Air, Smoke, and Cooking Odors Escape While Rain Stays Out
  • Available in Translucent White, Smoke Tint, Shell-white(Almond), Silver and Champagne
    • $_35Prevents Heat Build-up
  • Made of High Density Polyethylene with maximum UV Protection
    • Not recommended for use with high-powered ventilators
    • Fits over most 14″ x 14″ Standard Roof Vents
    • Installs easily! (See our Installation Guide)
  • 6 year warranty

As stated above these vent covers aren’t for roof vents with high powered fans; however they do make ones that will work with those as well!

If you can’t match up which roof vent you have yourself; take a picture from the non-opening (hinge side) side of the roof vent from the roof so that we can assist you. A clear picture of the hinge is all we need!
