While cleaning the roof on my 2014 Rockwood, I noticed a low spot near the rear of the trailer next to the roof ladder. this area always had a pool of water that would not run off. I thought by leveling this area with some self leveling caulk , i could eliminate this problem. I was wrong. It only made things worse. I used dicor and instead of solving the problem, it created a new one. Looks like as the caulk cured, it pulled the membrane up from the low spot. now there is an air pocket there. I may have voided my extended service contract. Just wondering if anyone has experienced this problem?
