While an RV’s roof is crucial, most RV owners don’t think about maintaining it. A well-maintained roof protects your investment and keeps rain and snow out of your rig. No matter how often you use your RV, you shouldn’t ignore roof maintenance. Luckily, it’s not as complicated or time-consuming as you might think to maintain your RV’s roof.
Know What Type of Roof You Have
Before you start maintenance, determine the type of roof you’re working with. Most RVs have one of three common types: rubber (EPDM or TPO), fiberglass, or aluminum. Rubber roofs are the most common and typically require more upkeep than fiberglass or aluminum. Although each material has its own characteristics, the basics of caring for it are similar.
If you’re not sure what kind of roof you have, check your RV’s manual or call the manufacturer. Knowing the material will help you choose the right cleaners, sealants, and techniques.
Make Roof Inspections a Habit
A good rule of thumb is to inspect your RV’s roof at least four times a year. If you use your RV a lot or store it under trees, you’ll want to check it even more often.
Start by giving the roof a good visual inspection. Look for any cracks, bubbles, tears, or spots where the sealant may be peeling. Pay close attention to areas around vents, skylights, antennas, and the edges where the roof meets the sidewalls. Water has a sneaky way of finding its way in, and these are the usual suspects.
Remember to check your RV’s interior for signs of a roof leak, such as water stains on the ceiling or soft spots. A small leak can cause a lot of damage if it goes unnoticed.
Keep It Clean
Keeping your roof clean makes inspections easier and extends the life of the material. Dirt, debris, and tree sap can break down roof coatings over time. If you’ve got a rubber roof, cleaning it every two to three months is a solid move. Use a mild cleaner made for your roof type and a soft brush or sponge. Avoid anything too abrasive or full of harsh chemicals—these can damage the surface.
Rinse the roof thoroughly after cleaning, and be mindful of the sides of your RV. If runoff dries on the paint or windows, it can leave streaks. Washing your whole rig after a roof cleaning session is a good idea.
Keep an Eye on the Sealant
The sealant on your roof is your first line of defense against leaks. Over time, it can crack, shrink, or pull away from the roof. When you’re doing your inspections, take a close look at all the sealed areas.
If the sealant is starting to show signs of wear, it’s time to touch it up or reapply it. Use a sealant that’s compatible with your roof material. Clean the area first, then apply the new sealant as directed. Some RVers prefer to reseal the entire roof every few years, while others just patch problem spots as they appear. Either way works—as long as you stay on top of it.
When to Call a Pro to Help Maintain Your RV’s Roof
While most roof maintenance is DIY-friendly, there are times when calling in a pro is the smart move. If you find a soft spot in the roof, major water damage, or a big tear in the membrane, it’s best to have a professional look at it. Catching problems early and getting them fixed right can save you a ton of money and stress.
Taking care of your RV roof is one of those chores that pays off in peace of mind. Keep it clean, check it often, and stay ahead of any issues.
FAQs on How to Maintain Your RV’s Roof
How often should I clean my RV roof?
For rubber roofs, every two to three months is ideal. For other materials, a couple of times a year may be enough, depending on your environment and how often you use your RV.
Can I walk on my RV roof?
That depends on your RV. Some roofs are built to be walkable, others are not. Check your owner’s manual. If you’re unsure, use a sheet of plywood to spread your weight or stick to a sturdy ladder.
What’s the best sealant for my RV roof?
Use a sealant designed for your specific roof type. Dicor and Lap Sealant are popular choices for rubber roofs. For fiberglass or aluminum, you’ll need something compatible with those surfaces.
Do I need to condition my rubber roof?
Some people like to use a UV-protectant or conditioner to help extend the life of their rubber roof. It’s not strictly necessary, but it can help if your RV sits in the sun a lot.
Is it okay to pressure wash an RV roof?
Generally, no. Pressure washing can damage sealant and even tear certain roof materials. Stick to a hose, gentle brush, and proper cleaner.
