There’s nothing worse than having to take your RV back to the dealership because a nasty leak has caused thousands of dollars’ worth of damage to your vehicle. Mold and dry rot in the subfloor, ruined insulation under the roof, damaged upholstery in the cabin – you name it, a leaky roof is behind it.
Thankfully, if you catch a leak early enough – before it does all that damage – you can fix the problem yourself without ever having to roll across the asphalt of your dealership if you don’t want to. In fact, if you’re handy, and you don’t mind climbing up atop the roof of your RV itself, there are any number of products you can use to reseal that roof and stop that leak in its tracks.
Why Pay for Labor?
Purchasing an RV is a massive investment, and it’s important to keep it in good shape. You can take your RV into the dealership for sure, but most RV technicians will simply clamber up onto your roof and do exactly what you could have done yourself. The only difference is instead of purchasing those cans of liquid roof RV coatings and doing all the prep work yourself, you’ll have to pay for the cost of the material plus all that labor as well. If you can’t climb up onto the roof of your RV for whatever reason, that’s one thing – and you should never attempt to do so if you have even the slightest doubt about your ability to do the repairs yourself safely. But if you’re able-bodied and you’re careful while you’re up there, you can protect your investment without it costing you an arm and a leg.
The Secret of EPDM Coating
So what are these miracle products that can keep the roof of your RV sealed tighter than a drum? There’s any number of liquid roof coatings products, but the best ones are made out of a compound called EPDM. Short for ethylene propylene diene monomer, the main ingredients in the compound, it’s a synthetic rubber that’s fantastically tough and durable, often used as a roofing material on commercial buildings with flat roofs – and it can be applied as a liquid.
Roll It Out, Let It Dry, Get On with Your Day
Liquid roof coatings that use EPDM are so easy to put on you’ll wonder what took you so long. All you need to do is give the roof of your RV a serious deep cleaning – scrub off any rust with a wire brush, fill any large gaps with RV-grade caulking, and power wash all that road dust and grime off – and then just use a paint roller to apply it to your roof once it’s dried. Around a gallon of EPDM-based liquid roof is enough to cover 42 square feet of roof, though if you want a particularly thick coating – never a bad idea – most liquid roof manufacturers recommend you only cover around 30 square feet per gallon.
