Bumper Pull roof questions.

[Rod Johnson]

I know there was some discussion on the roof strength of the 5ers, but...

Are the roofs on the smaller bumper pulls of similar construction?

I'm preparing to install several solar panels on my roof and I was curious if it was strong enough to walk on. What is the roof constructed of, 2x4s, 2x2's? 1/4 inch, 3/8 inch plywood?

I have a couple of boxes of roofing screws, with the rubber sealed washer that I was thinking of using, but the screw head is fairly pronounced.


Or maybe something without the gasket and a little more flush.



I can see several of the trusses through the sheating, and pressing in between them tells me I'm not getting up there. It looks like the worst of the panel mounts can be reached from a ladder so hopefully I won't have to get up there at all.

Rod,
I know most of these roofs can be walked on for inspection, maintenance, etc.

My roof is TPO over luan and 4 1/2" foam and the frame is aluminum. I am careful walking on it and use a board to spread out my weight if I'm sitting in one place for long. But it feels quite sturdy with no cracking. Since this was my first non-rubber roof, the service guy took me up there once and we both walked around looking at seams, etc. I'm not familiar with the roof on your trailer, though.

I'm not certain which of those screws I would use, but be aware if you have A/C ducts in the foam. Probably want to avoid those.

Well, I spent the afternoon up there on the roof.

Once up there, it was a bit easier to spot where the trusses were. I walked lightly, and felt my way forward. Just tried to be careful and step where the trusses here and not in between them.
