Why does my RV roof crack?

Prevent cracking with a cover or canopy.

Most RV and trailer roofs are made of rubber these days. Unfortunately, when damaged by UV rays, rubber cracks. That is the short answer. The sun is your true enemy. While water will ‘exploit’ cracks and damage in the roof, and if you get rained on and the water freezes and then expands, cracks will get worse, these faults will not happen if you limit your roof’s exposure to sun. If you don’t have an RV garage, what is there to do? Well, you have two realistic options: an RV garage canopy, or an RV cover. The canopy is more convenient: just drive in and turn her off. The cover, while cheaper, requires a bit more work and you’ll need to negotiate AC units, antennae and ladders to get it on. Either one will provide protection, you just need to determine how much work you want to do.
