2000 Sunline Solaris roof.

Can I walk on the roof of my 2000 Sunline Solaris roof without damaging it?

The Solaris name encompasses quite a few different models, so those who might be able to answer the question will need to know exactly which one you have. It's usually labeled right beside the door, in the format T-xxxx.

Unless your camper had the custom option of a walk on roof, or partial walk on roof, when bought new, you cannot walk directly on the roof without protection.

Odds are high you have the standard Sunline rubber roof with the bud board backing. This bud board is a heavy thick corrugate backing that the rubber membrane is glued to. Then the entire sheet is pulled over the roof rafters. As such there is no support between the rafters to hold your body weight.

To service items on the roof, you place down a trap, or other soft protection item over the rubber, to protect the rubber from abrasion. Then using pieces of 3/8" or thinker plywood, in approx 24" to 30" wide by 48" long, you place the wood sheets to span the rafters. Then you can kneel etc on the plywood. The rafters are close to 16" centers. Not all of them, but many. You can feel them being stiffer and solid under the rubber roof.

See here where I am servicing the roof AC unit. You have to use a solid ladder on stable ground to step off of and onto the roof. Be extra careful when getting on and off. Use the 3 point contact method. 1 foot, 2 hands, or 2 feet 1 hand etc. in contact with ladder or roof as you get on an off.





Hope this helps

John

I have a 2002 2553, and have always gone up on the roof, by using several layers of large corrugated (from old appliance carton). I never knew that it wasn't a walk-on roof.
Guess I lucked out. I'd probably still do the same thing, knowing that I shouldn't.

To help explain and show why you should not directly walk on a standard Sunline rubber roof, or the older metal roofs, see these pics of one of my project camper being taken apart of how the roof is made.

The rubber roof structure is a thin rubber membrane (0.040" thick) glued to an approx 1/16" to 3/32" dense corrugate sheeting called bud board (not exactly cardboard, more like the backing of a paper pad, only thicker) that is then draped over the top of wooden trusses or solid rafters. There is no support for point load weight ( like a person kneeling or standing) between the rafters. You can damage the roof or break through it.

The white topped, black bottom, rubber membrane glued to the bud board





The roof rolled up, the insulation lifted up showing the raters and in this case, water damage.






The rubber membrane and budboard off the roof


The rubber membrane and budboard laying on the ground


The older metal roof campers, while they did not have the rubber or the budboard, the thin sheet metal was draped over the rafters just like the rubber roof was. You can damage those metal roofs as well unless you use sheets of plywood to spread the weight of your body out across a larger area.

Hope this helps

John

Thanks,John. It's obvious why I should never have been up there. I think that the corrugated I used must have generally been over the rafters and no damage was done. I lucked out. Wonder how many Rv repair shops know this?

If they are not familiar with the Sunline brand, they may not know the roof make up. I myself do not know of any one else in the industry doing it like this. There may be, but not many. I have heard folks saying their dealer was up there and walking around.

On my son's 2006 Sunline when we looked at it at the dealership before he bought it, I saw the footprints on the rubber from an inspection they must of done up there. In this case, it looks like they sort of "high wire walked" on the rafters balancing at they went. The good news, they did not go very far. It's like they were standing there on the rafters looking over the roof, then backed up and got off. Thankfully as there was a prior leak that dried up but destroyed the budboard under it. Not much left other other than the rubber membrane as we found out after we opened up the roof for repair.
