Why Rubber Roofs ????

Just curious here ! Why did/does the TT industry use a rubber sheeting for the roof ??? As opposed to a more permanent material ( alum,fiberglass,metal )
As we all know, they need maintenance and will need to be replaced or recoated

Just a thought.

Jim

Because of the movement. rubber roofs are flexible and don't open up cracks in seams etc when shifting. That's my answer and I'm sticking to it!

Jim..
Cheaper and easier to use when constructed..
Almost always so in the RV industry..
Nothing wrong with them just more maintenance..

Check any flat roof, it is most likely rubber (EDPM) They have proven to be waterproof, durable, and VERY forgiving when the structure expands and contracts or MOVES. Metal roofs will leak at the seams, Fiberglas cracks, etc. I don't think it's to save money, it's because it's successful.

My first 5er; 1987 Roadway 24' ; had a metal roof. It had a tendency to " oil can ", in the sun shine, the kind of popping noise a metal oil can made when squeezed.
Anyone else old enough to remember when oil came in cans ?
Also discolored, and got hotter than the hub of .... , and transferred most of that heat into the interior, so although durable , not a perfect RV roof material ; still had to check the seams and be resealed.

Weight, money, movement.

I prefer TPO vinyl roofs now. Less maintenance on the membrane itself, cheaper, and tougher I think.

metal oil cans, yep. Sure would like to have a truckload of them now. Along with metal gunpowder cans. heck, anything but plastic is a collector item.

Rubber can be repaired, replaced, re-coated. Roof is all one big piece that flexes, stands up to hail and can be replaced in a day.

I preferred the one-piece aluminum roof covering on our 1992 5er to the EPDM material on our last 5er. The EPDM is cheaper to build than one-piece aluminum, but is much more susceptible to tearing from tree branches. It weighs more too. Our 92 5er went through a hail-storm, the aluminum roof was severely dented, as was the siding. Our insurance company replaced the siding and covered the roof with 1/8" luan and EPDM material. That added 200 lbs to the 5ers weight.

What i think is a combination of cost, weight and performance, but i think it one thing that make most TT almost disposable, in the sense that most older units ( like ours ) have a lot of rot from the PO not maintaining the roof. To make my point, look at Airstreams ( All Meta ! ) and how many old ones are out there.

What a great point about the air streams. Maybe someday with newer roofs like the Rhino and Linex we have longer lasting trailers.

I just got a visual about hail stones bouncing off a rubber roof!
