Sealing a Mobile Home Roof: What You Need to Know

When it comes to sealing a mobile home roof, whether you're dealing with an RV or a similar structure, there are specific steps and materials you need to follow for a successful outcome. This article will break down the process, recommend the right sealants and materials, and provide expert advice based on real-world experiences.

Replacement Process and Expert Tips

Have you ever witnessed the process of replacing an RV roof? It's not an easy task, and it definitely requires more than just a few tools and a roll of roofing material. As I've witnessed a customer replace a roof on an RV, I can attest to the complexity of the job. Often, the entire old roof needs to be stripped off before installing a new one that comes in one piece, typically requiring two individuals to complete. The result, however, is a brand new roof that looks great and can last for years with proper care.

DIY Considerations and Advice

While experienced professionals can undertake this task, for the average homeowner, attempting a roof replacement without the proper experience and assistance can be quite challenging. If you're keen on repairing leaks on your RV roof, I suggest starting with white urethane sealant. Urethane is unique in its ability to adhere well to substrates and won't crack or peel over time—characteristics that are essential for roof longevity.

To ensure the urethane sealant adheres properly, it’s crucial to clean the roof thoroughly. Over time, dirt, grease, and grime accumulate, making it difficult for sealants to stick. For a painted metal surface, I recommend using TSP (Trisodium Phosphate) and rinsing with clear water. This not only cleans the surface but also etches it, ensuring that the urethane sealant has a better bond.

Professional Roof Sealing Materials and Techniques

Liquid Roof Coating with Fibers

When applying a liquid roof coating that includes fibers, you'll find that the fibers help hold the liquid in place, reducing the likelihood of cracking. For hot days, this is especially beneficial. A heavy mix can either be squeegeed on or mopped on, but mopping it is the more recommended method. Using an 8-inch white wash brush may seem straightforward, but it doesn't coat the surface as evenly as a mop does. Be sure to follow the manufacturer's instructions for the most effective application.

rv Roof Sealer for Aluminum and Rubber Roofs

The choice of sealant and materials depends largely on what the roof is made of. For aluminum roofs, it's best to use RV roof sealer, a type containing silver for maximum reflectivity. Make sure the sealant is rated for at least 10 years, such as Jetcoat. Clean the roof meticulously before application, ensuring that the sealant adheres well. Similar care should be taken when working with rubber, PVC, or EPDM roofs, which can last up to 15-20 years. Due to their durability, these materials can withstand harsh conditions and are less prone to needing replacement.

Historical Context and Maintenance Tips

Interestingly, the historical context of roof sealing paints a different picture. In the 1950s, when my father was pioneering in the caravan and camper industry in Australia, obtaining parts and materials like screws and rivets was incredibly challenging. Stock shortages due to the war, combined with the absence of many modern sealing materials, made it necessary to be resourceful and innovative. Dust and water intrusion were a significant concern at the time, leading them to leave the front window slightly open as one foolproof way to prevent leaks.

However, with the advent of modern materials and techniques, effective sealing can now be achieved with minimal environmental compromises. Modern sealants and maintenance practices have significantly improved the longevity and performance of mobile home roofs.

For DIY enthusiasts or professionals, the key to success lies in thorough preparation, quality materials, and following best practices when applying sealants and coatings. If you're considering roof repairs or sealing, proper preparation and adherence to professional guidelines can make a world of difference in the appearance and durability of your mobile home roof.
