Replace whole deck
In This 20’ Rv we had to completely remove not only the roof membrane but also the whole deck itself and replaced it with a new one. The owner of the RV chose the Silicone Sandwich option (Silicone + Reinforced Fabric + Silicone). Really a bulletproof roof that would last way over 20 years. The job was finished within 3-4 day for $6500 total cost.
