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” +/-).
Recreational Vehicle (RV) roofs have to endure weather conditions of every other type of roof but also need to handle 70 mph winds on the highway. The roof will flex and twist as the RV is in motion and endure the occasional low hanging branch at a campground. Damage can happen and, when it does, a permanent waterproofing repair tape is often the best solution.

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.
