Prepare The Roof Surface

The first step in repairing an EPDM roof is to prepare the roof surface to receive the patch. EPDM has carbon contained within the membrane, and as the membrane ages, the sheet develops a carbon film that can be seen if you rub a hand across the sheet. This carbon film, as well as dirt and other oxidation, must be cleaned from the surface to ensure that the patch will stick and perform well over the long-term.

To clean the roof surface, use a cleaner that does not leave a residue. Many manufacturers recommend an all-purpose household cleaner, such as Simple Green or Spic-and-Span. Wash the patch area, cleaning well beyond the area where the patch will be applied. Use cloth rags to remove the oxidation from the surface of the EPDM and to remove all traces of moisture.

    Flat Roof Repair using Super Silicone Seal | EPDM Rubber roof repair | Easy DIY in 5 min

    This rubber roof on a New York home was installed in 2011. Most of the work has proven durable but five years after initial work a couple of roof seams had failed, particularly where the new EPDM roof had been seamed against older EPDM sections by gluing down the EPDM to the paper surface of older insulating roof panels below.

    You can see, stuck to the under-side of the peeled-up EPDM, the wet paper coating that formed the skin of the insulating panels under the EPDM.

    That paper contamination on the new EPDM under-side means that simply gluing down this seam again wont’ be a reliable repair.

    Instead it’s necessary to clean and seal the seam using a surface-applied strip of repair material.

    How To Repair Aluminum Rv Roof

    Have a metal roof on your RV? Heres how to seal and repair their punctures.

    Resealing aluminum RV roofs

    For aluminum and other metal RV roofs, resealing is done with a special coating designed for the material, such as Dicors Metal RV roof coating. This forms a rubber-like top layer and is resistant to mildew and rust.

    Of course, you wouldnt apply a thick white coating to a rounded metal RV like an Airstream. For these , sealing joints and rivets with a caulking gun is essential.

    Repairing punctures or tears

    Depending on the size of the puncture, you may be able to repair your metal roof with a peel and stick patch. Make sure to buy one that is designed for metal roofs, as the adhesive formula is a little different. Simply clean the area, stick the patch over it, and roll out air bubbles with a small roller.

    For more significant damages, the best way to repair a metal roof is by replacing the metal panel, which is a process that will vary depending on your particular RV.

    Inspect The Roof For Damage


    You want to take your time with this step. Inspect the roof thoroughly for signs of damage. Start with the surface area after its clean and dry and then move on to the seams.

    Assess the type of damage on your roof. This will determine what action you should take going forward. If you just need to seal the roof in some areas, the job is quick and simple.

    If you have to repair structural damage, it will take more time and care.

    How To Repair Rubber Rv Roof

    There are three main types of repairs that you may come across: applying a sealant to the roof, resealing joints, and patching holes and tears.

    Applying sealant to the roof

    If your EPDM or TPO rubber roof is looking chalky or flaky, its likely due for a fresh coat of sealant. Over time, the top layer protective coating breaks down, leaving your roof more susceptible to leaks and UV damage.

    Reapplying sealant isnt too difficult. When purchasing the rubber roof coating or sealant, be sure to have your RV measurements in mind so you get the right amount. After cleaning the entire roof and letting it dry, you can coat the roof with a roller, much like you would with paint.

    Be sure to read and follow the proper prep instructions detailed on the sealant container.

    Resealing joints

    More often, RV owners have issues with leaks around edges or joints rather than through the membrane itself. Antennas, screws, vents, A/C units, and other rooftop protrusions have sealed seams that are prone to cracking and peeling, allowing water to seep in.

    Joint reseals can be done with a tube of self-leveling sealants. Simply follow the prep instructions on the bottle, and caulk around the joints. Even if there is no obvious damage, resealing joints periodically is one of the best ways to prevent leaks from happening.
