Lance trailer “flat roof” makes roof water ponds -- problems

In August of 2014 my family and I purchased a new Lance 1685 trailer to replace our 10 year old 5th wheel. We liked what we thought was a well designed and built trailer. That is why we bought it. On this forum I previously posted the difficult problems that first came to light in 2015 when we were about 1000 miles from our Seattle home in the Nevada/Utah desert. That being (1) the Norcold refrigerator failed at higher altitude and (2) the slide unit jammed when opening and closing. Eventually, after several months, these items were fixed via the warranty process. But not until after these two problems pretty much ruined our long planned rv trip.

Especially annoying was Lance’s refusal to let me bring the trailer to their factory for them to fix the problems, even though I happened to be not too far from its factory when the problems occurred. I was told Lance was busy making new trailers at its factory and had no time to fix covered warranty problems on a unit it had recently built! Lance advised that I could try to find a “nearby” Lance dealer to fix the warranty problems. That process, it turned out, would take at least a month, probably more, all the while being about 1000 miles from home, at our sole living expense, no help from Lance. Not possible of course. We had to return home as best we could. After getting home Lance took many days to review their construction defects and authorize one of its dealers to fix the issues. After that, I waited for Lance to ship new parts to its dealer, and then get those parts installed.

I concluded then — my opinion only, others may differ — that Lance’s after-sale customer care could be greatly improved. It appeared to me that Lance was primarily interested in building and selling new units to new customers, as compared to promptly fixing its construction defects in its existing customer’s recently built trailers. I believe that was why Lance refused to let me bring the trailer to its Lancaster factory, which would have the needed parts on hand as well as experienced folks to quickly fix the problems. Unlike the situation with the Lance dealers.

But I hoped for the best going forward. No serious problems until December 2017, when a small hole (about 1/4” diameter) appeared for the first time in the Lance selected and installed roof sealant for the front vent over the queen bed. Normally such a small hole would let just a little water through a slightly crowned roof, no big problem, easily fixed. But it turns out Lance chooses to design and build trailer roofs that can pond water, rather than shedding the roof water. Lance calls their roofs “flat roofs”. But the roofs are not truly flat, but instead can pond water instead of shedding all the roof water. What is the purpose of a roof? As I see things, roofs are supposed to shed water, not collect and pond water, much of which can then go through a small hole when/if the Lance selected and installed sealant fails.

Lance tells me:

“… Lance has designed a flat roof on this unit and it has been meet with success. Maintaining the seals are part of that success. Lance can’t recommend a modification to its original design…. I regret to inform you this is not a warrantable situation that Lance can participate in financially…”

I've some pics of the damage to my unit from the ponded roof water, but don't know how to attach them here. Along with pics of some of the roof ponding. I’ve sent these pics, and additional pics, to Lance a few weeks ago. Let me know if you want a look, and I'll email the pics to you. Or you can look at them on the Lance owners website - they are posted there. I offered to let Lance examine the roof ponding on its so-called “flat roof” and the damage to my trailer. Lance declines. Lance says (I summarize) it’s my problem alone.

What’s the point of bringing this experience to this forum? So that others with Lance trailers with so-called “flat roofs” (which actually can pond water, instead of shedding water like roofs normally do) can consider taking steps to avoid possible problems and damage to the interior of your trailer. With the benefit of hindsight now, such steps might possibly include:

(1) consider a trailer with a slightly crowned roof that sheds water, instead of ponding water. A flat roof design that relies solely on "sealant" strikes me -- others may differ of course -- as very poor and very risky for the customer. Nowhere in its sales literature that I have does Lance disclose the fact that its flat roof design ponds water that can then all drop into the interior through a small hole in defectively installed sealant.


(2) consider calling Lance and asking whether you can store the Lance trailer so that it is “out of level” front to back and side to side, so that the so-called “flat roof” then sheds more ponded water. Please note that the Lance Owner’s Manual says the opposite — on page 115, the Lance Manual (in the Short Term Storage section) states: “Park the trailer as level as possible front to rear and side to side.” The Long Term Storage section says the same.


(3) whatever else you think appropriate. For instance, if/when it rains or snows during a camping trip, consider the pluses and minuses of having the trailer “out of level” to a degree that reduces or eliminates roof ponding on your Lance trailer. Keep alert for the possible effect on the refrigerator of course, and anything else Lance suggests.


(4) consider spending quite a bit of money every few years attempting to deal with a so-called “flat roof” design that, in many cases at least like mine, ponds water onto the roof, awaiting even a small hole somewhere, to drain into the interior.


(5) be thankful if your particular “flat roof” happens to shed all the water when the trailer is level, instead of ponding water.

Best of good fortune to all, and happy camping!

Not trying to be nasty, but I think your issue is due to lack of preventative maintenance - from the looks of the roof pictures.

Thanks to everyone. SoundGuy's post tells me how to upload pics here, and I'll try to upload the pics of the ponds on my Lance 1685 roof and the extensive damage inside the trailer. If for some reason pics don't upload, I've managed to upload them on the iRV2.com travel trailer forum, and the Lance Owners forum, and you can find them there. Or send me a message with an email address and I'll send the pics to you. Of course I sent the pics to Lance last month, and offered them the opportunity to look at the roof ponds of water on their so-called "flat roof", which is not flat. And the extensive damage. Lance declines to view the roof ponds or the damage.

Here goes my attempt to correctly upload the four pics here, which should be below, if all goes well for me. My apologies if I don't get it quite right. Best to all, and happy camping.

There is another reason I don't like the flat roof aside from the aforementioned reason of water pooling.

A flat roof doesn't allow for ducted AC. My previous TT, a Skyline Koala 21CS had a flat roof. The AC just dumped cold air into one area of the trailer, and was a bit nosier too, at least to my ears.

My Jay Flight 23RB has the trussed roof system, and it has space for AC ducts. I like the cold air spread through out the TT.

Agreed, but Lance trailers are not exactly cheap or considered entry level.

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.

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)

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 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.

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.

Too many geezers, self appointed moderators, experts, and disappearing posts for me. Enjoy. How many times can the same thing be rehashed over and over?

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 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
