Solaris Roof Strength

I have a 2003 Solaris 2475 and purchased a cover and want to stand on the roof to put it on. Is the roof strong enough to support a 180 pound man. Any advise will be appreciated. Bob

NOPE!! The rubber membrane will support very little weight.

Get yourself a 2'x4' piece of 1/2" plywood and a slightly larger carpet remenant. Place the carpet on the roof to protect to rubber roof and place the plywood on top of it, spanning the roof rafters. That will support you.

The rafters can take the weight but the roof span inbetween them cannot hold you. Like Mack stated you need to spread out the load to the rafters to support you. You can feel them under the rubber. They are on 16" centers for the most part.

See here: Need a good sturdy ladder to get up there.

Then put something down to protect the rubber from abrasion. I use a canvas tarp but outers have used old carpet or anything cloth like to not have the plywood diretly on the rubber. I am servicing the AC unit in this pic.

I use 5/8" thick plywood pieces 2 foot x 4 foot as those are what I have laying around. Wide enough to span 2 rafters and light enough to lift going up the ladder. I would not go much thinner then 3/8" thick plywood. 1/2" and 5/8 works well. 3/4 is great but heavy to get up there.

Hope this helps

It's not so much about being cheap as it is for weight reduction. Plywood sheets weigh A LOT, so putting this board stuff up there is much less weight.

Will you fall through? Probably not.

Will it damage the roof if you walk on it without spanning the rafters with plywood as shown above? Maybe.

It's been a long time since I've had a Sunline TT which had that style of roof. My Sunline 5'er had a walk on roof. So does my newer fiver. It would be hard to go back to the non walk-on style. I'm up on my roof, it seems like, once a week. Of course, with a smaller trailer it's probably not that big of a deal.

I've seen many a dealer walking all over non walk-on roofs. Scrubbing them down with abrasive stuff and probably harmful soaps before reselling used units. That doesn't mean it's OK, though.
