    Ideally, an RV roof should be resealed every year and entirely replaced after 10 years of use. Not taking proper care of your RV roof will lead to water leaks, high damp levels and even mould inside the motorhome.

    The sealant that RV manufacturers use to keep RV skylights and roof vents from leaking can gradually dissolve over time. Sunlight, alternating hot and cold temperatures, and even heavy rain can take a toll.

    If you notice even a small amount of water coming through the skylight of your RV, it is most likely time to replace the sealing caulk. Before jumping into action, however, make sure that the water you are realizing is nothing more than condensation that forms on the cold surface inside the skylight.

    A roof sealer is essential to prevent leaks, leaks and moisture as well as the accumulation of fungi and bacteria. It is very important to apply it, especially in areas where humidity is frequent, where rainy seasons are very long or where weather conditions are very adverse.

    What Kind Of Rv Roofs Can Be Repaired With Flex Seal

    There are two primary materials designed and used specifically for RV rubber roofs. They are EPDM and TPO. Both TPO and EPDM are classified as rubber roofs, but they are a bit different in form and appearance.

    TPO

    TPO RV roofing is the most popular option for RV roofs in use today. It is a popular choice because it is inexpensive to buy and its white. The TPO membrane has a shiny, laminate appearance with the outer layer having a plastic look and feel to it. It can either be fitted with screws or otherwise mechanically attached. It can also be glued down. When it comes to detailed work and seams, both glue and heat can be used to create a seal.

    EPDM Rubber Roofs

    EPDM is a second popular option for RV roofing. It differs from TPO in several ways. EPDM is a synthetic rubber material which can be vulcanized. This means it can be dried and cured to form sheets. Alternatively, you can also use EPDM in its un-vulcanized form. In this form, itll never completely solidify. Its relatively common to use both EDPM types together for an RV roof. Vulcanized EPDM would be used for the roof membrane, while non-vulcanized EPDM can be used for any flashing or detail work. EPDM rubber roofs are usually maintenance-free for about ten years, but they will oxidize over time.
