Roof weight limits???

I have a 2012 Cherokee 28bh. My question is what is the weight limit of the roof. I'm a big dude (340lbs) and I have been on the roof a couple of times for cleaning. The last time I was up on the roof I thought that maybe I could cause damage from walking on it. I have of couse been very careful of where I step and tread lightly, just curious if anyone had any idea of what the limits are.

Your ladder should have a weight limit rating on it.

I've never seen a weight limit on any roof, of any brand of RV. Most just list "Walk On Roof", which I suppose you could take with a grain of salt. Every one I've walked on flexed quite a bit, but figure you're on 1/2" plywood at the most on a top of the line unit, or 3/8" or less on the entry level, each having rafters on 16" centers. The ladders are pretty flimsy and usually rated at 225 I think. If you're careful and walking mainly toward the edges and steering clear of any vent openings, I think you'd still be fine. I do like you, tread lightly.

At least in Heaven, RVs will be perfect, and I won't have to keep fixing them.

I am only 225 lbs and I don't get up on the roof of my 2012 V-Cross 275 fiver. I can do most things from a latter leaning over. If I had to, I would lay on the roof to reach. That way my weight would be better distributed.

At 340 lbs, I would say you're pushing the limits, if not exceeding them. I weigh in at 215 lbs and I would not venture on the roof , only if I absolutely had to. The couple of times I've been up there, I feel the squishing of materiel beneath my feet.

As long as you are careful where you step, I think you are fine. My Roo has 1/4" plywood sandwiched on each side of a piece of styrofoam with only a couple aluminum studs where the ac mounts. I feel some flexing in spots when I walk on it, but I don't see how they would design a roof that you can't walk on. Its neccessary to clean / re-seal / cover the camper. And the collective weight of the snow in the winter has to put a pretty heavy load on the roof too.

I can see why people might choose not to walk on the roof, but FR certainly doesn't seem to say you can't

I don't know if this is true for the majority of RV/trailers or not but my "walk on" roof is 1/8" plywood exterior, Styrofoam core and 1/8" luan interior. There are 1/8" steel hard points in various locations and a wood "H" frame across the middle. Personally I would not walk on it unless it was an emergency repair of some type where I didn't have access to a ladder.
