If you've noticed a moist spot on your own ceiling or a musty smell after a storm, understanding how to repair a roof on a camper is probably at the top of your to-do list. It's one of those jobs that every single RV owner dreads, but honestly, it's less intimidating because it seems once you get up there and notice what you're working with. Taking care of it yourself can save a person a mountain of cash compared to what a service center would cost, and you'll sleep a lot better knowing your rig is bone-dry.
Figure out what type of roof you really have
Before you run out and buy a lot of sealant, you might have to know what your roof is usually made of. Most modern campers use a rubber membrane, either EPDM or TPO. EPDM feels a bit like a bicycle inner pipe and usually leaves a chalky deposits on your fingers. TPO is a bit more "plasticky" and doesn't usually chalk up.
In case you have an older or even vintage rig, you might have an aluminum or fiberglass roof. This issues because the chemicals in certain sealants will certainly have through certain materials. You don't want to use a petroleum-based item on an EPDM roof, or it'll bubble up and turn into a sticky mess. Verify your owner's manual or do a quick search associated with your model season to be 100% sure before you start.
Hunting down the original source of the outflow
Water will be sneaky. Just due to the fact you see a drip over your bed doesn't indicate the hole will be directly above it. Water loves to travel along the internal frame or even the wiring prior to it finally chooses to soak by means of the ceiling panels.
Get a ladder and get up there. You're searching for cracks within the caulk close to the vents, the particular AC unit, the TV antenna, plus along the aspect seams. Even a tiny hairline split is enough to let in a surprising amount of water with time. Push down on the roof material near any suspicious spots. If it feels soft or "crunchy, " you've likely got some wood rot underneath that needs attention too.
Get everything squeaky clean
I cannot stress this plenty of: nothing at all sticks to a dirty roof. If a person try to use new sealant over old, grimy crud, it will peel right off within a few several weeks. Start by providing the whole roof a good clean with a non-petroleum-based soap. A great deal of people use a simple combination of Dawn dish soap and water.
For the specific areas you're repairing, you'll would like to go a step further. Use a stiff brush as well as a plastic scraper to eliminate any loose or even peeling old sealant. You don't necessarily have to clean everything the method down to the particular membrane when the aged stuff continues to be fused well, but you desire a clean, strong surface. A fast wipe-down with some denatured alcohol on a rag will get rid of any lingering oils and make sure your patch job actually holds.
Patching small holes and tears
If you've snagged a low-hanging branch and ended upward with a small tear, you don't need to update the whole roof. For these small "oops" moments, most people swear by EternaBond tape. It's fundamentally a super-sticky, waterproof tape that is definitely designed to last for a long time.
Cut a piece of the tape that overlaps the tear by at least an inch or two on all edges. Round off the edges of the record with scissors—this prevents the corners from catching and peeling up later. Peel from the lime the backing, place it down, and make use of a small roller or even the back of a spoon to really press it directly into the roof. The adhesive is pressure-activated, so the tougher you press, the better it provides.
Resealing the particular vents and seams
The most common location for leaks isn't actually a hole in the roof material itself, yet a failure in the sealant around the stuff poking via the roof. This is where you'll use "lap sealant. " Most people use a brand name called Dicor, and they make two versions: self-leveling and non-sag.
For the flat areas of the roof, you would like the self-leveling kind. You simply squeeze it out of a caulk gun round the foundation of your vents or along the particular seams, and it slowly flattens away to create a smooth, waterproof cover. If you're functioning on the up and down edges or maybe the part of the camper, use the non-sag version therefore it doesn't simply run down the side of your rig and look like a mess.
Coping with a complete roof recoat
Sometimes, the roof is just old. If your silicone membrane is looking thin, stained, and has numerous small spiderweb cracks, patching individual spots is definitely like trying to plug holes within a colander. In cases like this, you're looking at a full recoat.
This will be a bigger work, but still totally doable for a DIYer. You'll purchase a liquid roof coating—usually a silicon or acrylic-based product—and literally paint it on. You'll the actual edges and close to the vents along with a brush very first, then use a roller for your huge open spaces. It usually takes 2 coats. The result is a smooth, white finish that will reflects heat and keeps the inside of of the camper much cooler during the summer. Just make certain there's no rainfall in the prediction for at least 24 to 48 hours, because this particular stuff needs period to cure.
What about the AC gasket?
If you've examined all your seams and everything appears perfect but you nevertheless have a leak, examine the air conditioning unit. The AIR CONDITIONING isn't usually adhered or caulked straight down; it sits on a thick foam gasket and is kept in place simply by four long bolts accessible from the particular inside.
More than time, that gasket can compress or maybe the bolts can vibrate loose. Take the plastic shroud away from the AC unit inside the camper plus check those mounting bolts. If they're unfastened, give them a snug turn (but don't go insane and crush the particular gasket). If the gasket is completely pancaked or brittle, you'll have to mind back up to the roof, lift the unit, plus swap the seal out for a fresh one. It's a two-person job due to the fact those AC products are heavy, yet it's a really common fix.
Staying safe as you work
Functioning on a camper roof can be sketchy. They aren't always designed to hold a load of weight, so try to remain on the "rafters" or use a bit of plywood to distribute your weight in the event that you're worried regarding stepping through.
Also, a wet camper roof is incredibly slick. I've seen individuals slide right off the particular edge like they're on a playground slide. Wear shoes or boots with good grasp, and maybe keep the ladder transferred to wherever you're currently working therefore you have a quick escape path if you start to feel shaky.
Maintenance is definitely better than repair
Once you've figured out how to repair a roof on a camper and in fact finished the job, you'll probably never desire to try it again. The particular best way to avoid a repeat performance is to wake up there every three to 6 months for a quick inspection.
Look for fresh cracks, check for any "pumping" (where the sealant pulls away from the steel or plastic), and maintain the roof clear. A little little bit of preventative maintenance—like a five-minute touch-up with a caulk gun—can help you save from a multi-day repair project down the road. It's much easier to fix a tiny crack today compared with how it is to replace a rotted-out ceiling next year. Keep it clear, keep it covered, as well as your camper may stay within the family for a long time.
