If you're looking for a way to brighten up your RV lighting but wan to save power, RV Skylights are a great source of natural light. Usually, these lights can be found in the kitchen areas and bathrooms, but can be installed virtually anywhere. However, there are many different types and parts to these skylights. We found the best RV skylights on the market just for you and reviewed them in this ultimate guide!
How Do RV Skylights Work?
When it comes to RV Skylights, they aren't just a simple window on the roof of your beloved RV. Generally, an RV skylight consists of two piece: the inner liner and the RV skylight dome.
The inner liner (dome) is usually a clear cover that allows beautiful natural light into the room. Also, these piece is screwed into a plastic frame called an RV skylight inner garnish that is screwed into the ceiling.
Then, the RV skylight cover is screwed and sealed into the roof on the outside. Usually, you can use an RV skylight sealant to secure the skylight in place and prevent outside debris from entering.
How To Replace RV Skylights
11 Steps to Replace an RV Skylight
1. Make sure you have the right sealant.
Once you have acquired a replacement dome, read the instructions to find out what type of sealant the manufacturer suggests.
2. Use a putty knife to scrape away old sealant.
Using a putty knife, making sure not to damage your roof. Scrape away the old sealant, so that you can access each of the screws in the original RV skylight dome.
3. Remove the original screws.
Now that you have access to them, remove them! Assuming that the original screws are the self-tapping kind, you’re going to reuse them. Be sure to inspect the screws to make sure that they aren’t damaged or rusted, and keep any that are still useable.
4. Remove the old RV skylight dome.
Use your putty knife to pry between the old dome and the roof, loosening the dome a little at a time, until you can pull the dome away from the roof completely. Again, be careful not to damage your roof. If your RV has a rubber roof, be especially careful not to rip the roofing material.
5. Scrape away any remaining sealant.
Use your putty knife to scrape away any of the old sealant that is still on the roof, after removing the dome. You can use Mineral Spirits and an old rag to get more of the sealant off. (Be careful of using Mineral Spirits if you have a rubber roof.) Get as much of the old sealant off of your roof as possible, but don’t worry about getting every last bit of it as you’ll be using new sealant to cover it as well.
6. Cover original screw holes with a bead of manufacturer’s recommended sealant.
Next you’re going to put some new sealant on your roof. Again, be sure you use a sealant recommended by the manufacturer. Run a thick, single bead of sealant around the opening for the skylight, making sure to cover up each of the original screw holes. The new RV skylight dome may not have the same screw hole pattern as your original. That’s okay! You’re sealing the old holes with the new sealant and will create new holes where needed.
7. Dry fit your RV skylight replacement.
Take your new RV skylight and place it on top of the bead of sealant you just laid over the screw holes. Wiggle the replacement dome back and forth, to flatten out and spread the sealant and create a bond between the new dome and your roof. Center the skylight over the opening in your roof.
8. Use self-tapping screws to fasten your RV skylight replacement.
Remember that the new holes may not match the old holes, and that is okay. Self-tapping screws will create new holes to attach to your roof. It’s possible that your new skylight dome will have more holes in it than your original dome, so you may need extra screws for the job. Tighten each of the screws, until they just begin to flex the plastic of the new dome. Do not over tighten the screws or you may find yourself having to replace your brand new skylight replacement. While doing this, if you see some of the sealant coming out of the sides of the dome or through the screw holes, that’s okay.
9. Run a bead of sealant around the edge of your new skylight.
Use sealant around the edge of the skylight to create another barrier between water and the inside of your RV.
10. Cover each of the screw heads with sealant.
Use your sealant to cover up the heads of each of the screws that you have used to fasten your new RV skylight.
11. Let the sealant dry, then check for any trouble spots.
As the sealant dries it may shrink up slightly, so you’ll want to check the skylight again after a few hours. If there are any areas that look like they could use another bead or covering of sealant, cover them now.
