Single-ply roof membranes are plastic or rubber roofing materials that consist of one thin layer of material. The most common types of single-ply roof membranes are EPDM rubber roof membranes, PVC roof membranes, and TPO roof membranes. These roofs can vary in thickness from 40 mils to 80 mils (1/16” +/-).
Winter is officially here and for many of us, the cold weather has arrived and looks like it’s here to stay. If your RV’s roof is not yet covered with a blanket of snow, now is the perfect time to seal up any areas where leaks may be present. Keeping moisture out of your RV will prevent unwanted damage, mold and other costly repairs.
There are many sealant tapes to choose from if you are you looking for a simple solution to seal a hole, seam, or tear in your single ply roof. So, the question is, how do you choose the best tape for your needs? Most are competitively priced, but do they match up qualitatively?

RV’s, Campers, box vans, and trailers are subject to hurricane force winds that can drive moisture through the smallest of gaps when traveling at highway speeds. Often the roofs of these structures develop leaks as the vehicle ages. 4EvaSeal Multipurpose Tape stops leaks, stays bonded, and prevents water intrusion. It is also extremely flexible and UV stable.
The 4EvaSeal® Multi-Purpose tape shows superior performance properties to competitive brands.
The following is the first comparison in a series where we will be testing and comparing the performance properties of 4EvaSeal® Tapes to other manufacturers.
A commonly used brand is Eternabond®. Other brands that are not as common, but still widely used, are Sika® Multiseal Plus and Dicor DiSeal. Since these other brands provide similar performance to Eternabond®, we determined a comparison between 4EvaSeal® and Eternabond® would be the most appropriate.
Part 1 of this 2-part series we discussed the importance of inspection, cleaning, and profiling.
The final step to surface preparation, and most often overlooked is environmental monitoring.
It is important to understand the environmental limitations of self-adhesive materials and to ensure that the application of these materials is performed within their limitations for a successful application.
The limitations of these products are typically found on product data sheets. Always contact the manufacturer if the product data sheet does not contain information on how temperatures and humidity can affect the application of the product intended for use.
Peel-and-Stick seal and waterproof tapes are commonly used to prevent water from intruding into structures such as homes, commercial buildings, and recreational vehicles. These tapes provide outstanding long-term and life time performance when used properly. Proper use of tapes refers to not only the service environment but also how the tapes have been applied to details of complex shapes and penetrations and, most importantly, how well the surface has been prepared for application.
Roof gutters are designed to collect rainwater from roofing systems and divert water away from the building to prevent water damage to the building structure. When roof gutters fail, water can interact with the building structure and causing staining, rot, mold, and leaks into the building interior. The point of failure (“the leak”) is nearly always at the point of the seaming the gutter. To prevent this from happening, it is important to understand how gutters are constructed, areas that can fail, and best practices to repair them.
To maximize the performance of any sealant tape, the surface to which the tape is applied must be clean and prepared properly. A properly prepared surface will allow the tape to achieve its greatest bond. The better the bond, the lower the chance that the tape will peel, dis-bond or separate from the surface at some point in the future.
There are many sealant tapes to choose from if you are you looking for a simple solution to seal a hole, seam, or tear in your single ply roof. So, the question is, how do you choose the best tape for your needs? Most are competitively priced, but are the quality of the tapes equal as well?
