How to Install an RV Roof Vent

Explore America's Campgrounds

RV camping is enjoyed by millions of people each year. The ability to take the comforts of home to the wilderness is one reason so many people enjoy their RV. RVs are small, however, and can get too warm in the summer. Adding a roof vent can keep your RV cool and greatly aid in the total enjoyment of the camping trip. This is something almost any RV owner can do by purchasing an RV vent and using some normal household tools and supplies.

Items you will need

  • Roof vent kit

  • Flat head and Phillips screwdrivers

  • Utility saw

  • Silicone caulking

  • Cordless drill

  • 1 inch drill bit

  • Measuring tape

  • Marking pen

Park your RV on a level location. Chock the wheels. RVs should be level and stable prior to doing any work.

Use the exterior stairs on the RV or a ladder and climb on top of your RV. Identify a location for the vent. Measure and mark a 14-inch square at this location. Use the proximity of existing roof penetrations (such as waste tank vent line) to make sure this location will be in the desired area in the interior of the RV.

Drill a 1 inch hole at one corner of the 14-inch square. Starting at the 1 inch hole cut open a 14-inch square opening using the utility saw.

Apply a strip of silicone approximately 1/4 inch wide along the edges of the 14-inch square opening.

Place the RV roof vent on the 14-inch opening and press down to seat the vent on the silicone caulking. Place the screws provided with the vent into the holes pre-drilled into the vent flashing. Use the appropriate screwdriver to drive screws until tight.


  • Some roof vents may require an opening slightly larger or smaller than 14 inches. Always follow the manufacturer's installation instructions when cutting openings in your RV.
