Step by Step Guide on How to Seal Corrugated Plastic Roof

Step One: Find the Leaks

To find the leaks, have an assistant hold a hose sprayer in each location that you think might leak. Then, turn on the water and look for places where water is coming in through the roof. To fill up your entire roof with holes, you will need to have your helper stay in one location for about 10 seconds until you’re sure that there is no water coming in.

Then you will want to move on to the next hole and repeat this process until all of your holes are identified. Ensure to check the inside of all seams, corner pieces, and anywhere else you can think of where water might get in. Once you have made it through your entire RV and checked all of the caulking, if there are any areas that you believe need more caulking, now is the time to apply it.

Step Two: Prepare to Repair the Leak

Once you have found all of your leak points, you should prepare to fix them. You will need to buy a silicone sealant and a caulk gun which can be purchased at any hardware store. Go ahead and buy the correct size as well, since roofing jobs can vary greatly in size. Once you have the tools, you will need to make sure that your roof is completely dry before applying the sealant. In order to do this, you can use a soft cloth or a brush to remove any leftover moisture.

Prepare to Repair The Leak

Once you have purchased the materials, go ahead and gather all of the tools you need to fix your holes. First, you will need a drill with a ‘hole saw’ bit that is the same size as your leaks. Make sure to get one that has an adjustable guide so that you can use it on any size hole up to 6 inches. In addition to the drill, you will also need an adjustable wrench. Next, you will need to turn off the main water supply to your home or business. Once that is done, go ahead and open up all of the faucets in your home or business so that the water can drain out of the lines.

Step Three: Seal the Leaks

Now that you have prepared your material and gathered your tools, you can begin to seal up all of your leaks. Start by marking the hole on each side of the roof, and then drill a pilot hole into the center. Don’t go too deep, though, since you don’t want to hit any metal. After your pilot hole is drilled, go back and hammer in the nails along the edge of the tar. Start at the bottom and work your way up to the top.

Once you have drilled the holes, go ahead and use your hole saw to drill the actual leak. To do this, you will want to apply several short bursts of pressure instead of one prolonged pressure from a fully depressed caulk gun. This will allow for smoother sealing without gaps in between layers.

Smoother Sealing Without Gaps

Once you have drilled all of your holes, put some sealant into each of them. You don’t have to go crazy with the amount, just enough so that it squishes out when you push on it. Go ahead and seal all of your holes this way, or until you run out of sealant.

Step Four: Finish Up

Once you have finished sealing all of your leaks, let the sealant sit until it has dried. After this, you will want to go ahead and caulk around the perimeter of each hole to give an added barrier against any further leaks. This is easy for anyone, but you might need someone else to hold one side while working on the other side.

Once you have caulked all of your holes, it is time to test out the roof again. If there are still any leaks after this process, they will be much easier to spot and fix since they will become smaller due to all of the added barriers against them.
