I can't understand why a mfg would have a flat roof and supposedly a premium brand. There lack of customer service is unacceptable in my opinion. Even my cheap Cherokee has a crowned roof.

X2 though I've read almost 100% positive about Lance, I've never understood the rationale behind the flat roof

The rational is that it is cheaper and easier to make the transition to the flat end at the front. Like everything else in this business it is driven by the numbers.

Flat roofs have been on the decline for years. For the very reason this thread is about. Manufacturers don't like to mess around with warranty claims and bad reputations when a simple change in construction can make a big difference. Lance, being relatively new to the TT buisiness still needs to learn this.

I would NEVER own a flat roof RV again.

I've had a few TT's with flat roofs and they all ponded a bit, but never had any leaks. My current TrailCruiser's roof is flat and ponds up but it doesn't bother me any. As someone said, maintenance x3.

Manufacturing cost rules everything. It's much cheaper to make a laminated roof flat as you already have the equipment used to make the wall panels. In Lance's case they most likely do not move enough product to justify the cost of the specialized equipment to be able to do this.

The big problem with a flat roof, is that there is NO margin for error on maintainence. You need to be on top of the caulking like it's a religon.

ONE mistake, and it's all over.
Of course if you check it every 2 months, and the caulking fails @ 59 days and it rains..... There will be those here that will claim you did not check it often enough.

Flat roofs need to go the way of the Do Do bird.
The RVing public can speed this process along by spreading the word on forums like this, and refusing to buy flat roofed units.

My roof is somewhat flat and has edge trim that allows water to pool against the trim. I used heroic caulking measures when I restored the roof but had one or two tiny leaks. I installed Eternabond tapes to every through hole and over the edge trim. That eliminated any leaks and it has been five years since the tape was installed.

The roof on the Dart is flat and it was a concern when we bought it. But I just put her slightly off level and all is good. I check the roof several times a year and have used a fair amount of Eternabond where I could.
So far, no problems. (Knock on luaun)

Lake effects on flat roofs is a big reason rv trailer/house trailer mfg moved to the crowned truss type ribs in the roof many years ago. I've seen water standing 1"+ deep around the A/C units especially on older trailers that the roof sagged with time.
Having been in the rv/mobilhome assy/repair side I'm surprised to hear any mfg would use that old system.
Maintaining them, especially with the old galvanized steel and later aluminum roofing material was time consuming if we wanted a the unit to last long term.
