My apologies if this has been covered elsewhere (I've tried searching through the various forum categories, but haven't been able to find anything specific). I've googled this and there's quite a bit of information out there, but more of it seems to be geared towards repairing RVs (much bigger than my trailer, which is about 15'), or preference when buying new.
I've been planning on an aluminum roof, mainly for the idea of durability, and because I initially thought it would be more straight-forward and easier to install/maintain. I also find mobiltec's videos great for instructing how to do this. From what I've read elsewhere though, issues of expansion/contraction due to temperature changes (which in my part of Canada, is quite dramatic) seems to be big con of aluminum roofing, regarding aluminum cracking and seals being disrupted. As well as motion of the trailer putting strain on seals and points of fastening. However, I have also read that these cons shouldn't be so much of an issue with smaller (in comparison to RVs) trailers?
So then I've also been reading about rubber roofing, there being the 2 main types. They're supposed to be cheaper and easier to initially install, and relatively easy to maintain. They're suppose to accomodate temperature changes, and should be easier to seal. This seems like a no-brainer when written out, but I have a hard time coming to terms with a rubber roof (and my skill with installing it) being reliable.
Can anyone shed some insight, or point me in the right direction to other helpful information?
