Bob, you are correct; the roof skin warranty is 10 years, but that is only on the material as supplied to Winnebago. The roof installation is one year, along with the rest of the motorhome. The roof panels aren't failing, so the 10 year warranty wouldn't apply. The roof SEALANT is what could fail, by seperating from the surface to which it is applied. The routine inspections will catch this, and the old sealant can be cut out, the area cleaned with a thinnner, and new adhesive/sealant applied.

By the way, if the sealant seperates from the roof panel or J channel, you won't have a water leak inside the rig because the J channel where the roof panel is tucked into doesn't have an opening into the wall cavity. But if a sudden strong gust of wind caught the roof from the side where the adhesive was no longer holding, the roof panel could 'flip' up out of the J, allowing the wind to get under the panel and tear it.

I ordered 2" tape from eternabond and am awaiting delivery. My question: When doing the seam along the sides do you overlap the awning rails? I can't see any other way to accomplish the sealing.

Nick,
I have not seen the roof connection on an '01 Journey, same reason I did not go into candy stores as a poor child! My MH has a combination metal molding, the top exposed area is the gutter shaped like a U, just under it is the awning slot shaped like a C. When I applied the Eternabond I inserted one edge into the top of the U and the opposited edge on the roof. Putting one edge into the U restricted its width a little bit and perhaps its ability to drain but I don't think it is appreciable.
I read a post that someone said they could not install the Eternabond because of the awning rail, maybe some models don't have the combination molding! Best way to find out is to get a ladder, either a 10' or extension so you can actually see what you have. Post us if it is not a combination molding so we can keep others informed.

We have a 2003 Suncruiser 33V and I wanted to know if Winne has fixed this problem on the later models or do I still need to be concerned about the separation?

Also, if the roll comes in 2" width, why bother cutting off 1/2"? Seems like it would take time and if you don't cut it straight, look bad?

thanks, jim

Jim,
Until recently the tape was not available in 2", only 4". I actually cut mine off 2-1" strips for the roof/gutter joint and used the 2" balance on the front and rear caps. You can use any width you desire.

Jim, I'm not sure what you mean by this. This roof design is not "a problem" unless one doesn't follow the roof to wall sealant inspection (and replacement as necessary) procedures. They are built the same way they have always been. The "sealant", really a urethane adhesive, is used to bond the roof material in the "J" channel. During the inspection, when you press against to roof panel just abouve the "J", if you see a gap between it and the sealant, it's time for some clean-out of that section, and replacing with the correct material, which on an unpainted fiberglass roof, is urethane adhesive, p/n 072889-10-000; $7.40 tube plus hazmat shipping.

CaptBill, thanks for the reply.

I define a problem' as a situation which requires attention in order to prevent extensive and compounding damage to the area in concern or adjacent parts/systems, outside of normal, generally understood wear/tear and common sense maintence (oil change, etc.)

Since Winnebago requires checking roof line sealant adhesion every six months, and making this a required' maintenance item, which if not done voids the warranty, proves they know this is not just an infrequent issue. How many other non-dynamic systems (dynamic being lubricants, tire air-pressure, etc.) on the MH do they require mandatory 6 month inspection or the warranty is void? NONE! The closest system to which the roof line sealant issue would apply would be the windshield. Yet, there is no 6 month inspection requirement on this. Why? Because there is no issue with failure on this system.

Why won't Winnebago just redesign the roof/"J" channel attachment areas to take care of this problem. Obviously they have known about this for years and I'm sure they have tried to limit their liability by making the 10 year roof warranty valid for the FIRST owner ONLY!!! This really pisses me off because we bought our 2003 Suncruser used, with 9,000 miles, and it was first registered just nine months previously. It still had three months of factory warranty remaining, but NO ROOF WARRANTY!!!!

Plus, in your post, you say the roofs... are built the same way they have always been.' My point exactly. Why not improve the design? Also, from the factory, why do they use in-correct' material instead of the correct' urethane adhesive?

This is why I called this a problem' and not a maintenance issue.

Please don't get me wrong. I love this MH. We can't wait to go out as often as possible and rant/rave about how great it is.

But come on! Call a problem' a problem when it really is and not a maintenance issue.

Thanks, jim

JIM: Your post is right on. It is succinct and IMHO should be on the President of WIT's desk along with a copy to your Attorney General. Our accepting the status quo is not going to get things made any better.

CaptBill, not to pick on you, but your last post about the replacement of the "correct" material for sealing the roof caught my eye. Are you saying that the tape is not a good idea or that one is better than the other? I am STILL waiting for the 2" eternabond tape to be shipped, 3 weeks and no light at the end of the tunnel. I talked to the guys at Roofers Tools and Equip. and they are rather casual about follow up on shipping or, who knows, maybe ordering as well.
I may cancell the order and use the caulk method so I can get on the road.

boy: Sent an e-mail to Winn. last night. They called me today and said to just inspect the roof seal and repair as needed. the person I talked to said to use silacone sealent/adhesive that you can buy from Home Depot or any hardware store. Do this every 6 months. Make sure you clean out the old material and wipe with alcohal to clean. Than fill the opening. We had a Pace Arrow with a rubber roof. Fleetwood also wanted it inspected every 6 months for the same thing.

Jim, I understand your point, but the reason that I don't think this is a "problem" or bad design is that of the tens of thousands (dare I say a hundred thousand?) of these Winnebagos built this way, you can only find a handful of people that have actually experienced a problem, and I would bet that of those that did, it is even a much smaller number that performed the routine inspection/sealant replacement per Winnebago. I think if Winnebago had a "bad design" in this roof, they would have stopped using it a lonnnng time ago, not just put a requirement for 6 month inspections in the manual.

What do you think about Monaco's requirement to inspect the sealant on all of their windows in their motorhomes, every 6 months. They say if you don't, there is no warranty on sidewall delamination. They even say that you may have to remove all the windows from the coach to properly clean off the seperated sealant and re-seal. How about that?

And I know that you've probably heard this before, but is it really different that making sure you weigh your motorhome, front and rear axles, and then routinely (weekly) checking air pressure and maintaining it as required. If you don't do that, and have a tire failure, you're sitting out there with no tire warranty.

With regard to the 10 year original owner warranty, yes it's a shame it's not transferrable, but I doubt anybody really has any warranty replacement during that 10 years anyway. Did you know that the warranty is only on failure of the fiberglass material itself, and not on the integrity of the completed roof? That's right, if the material failed (delaminated or whatever), they would replace that roof panel, but we'd still have to pay for the labor after the first year. And the warranty does not cover sealants, so that's a moot point anyway.

Do you know how your roof is actually made, and what holds it on? I am not being a smart A$$ here. Many people have heard so many stories flying around on the internet that they "know" they must be true.

Even without ANY sealant ever applied to the roof to J channel, your roof will not blow off, and it will not leak. That is by design. The roof is bonded to the supporting structure over the entire flat area. If water leaks into the J channel, it cannot enter the interior of the walls structure. See attached drawing at http://www.qrents.com/images/roof2wall.jpg. The J channel adhesive retains the edge of the fiberglass roof panel in the J, so if a VERY strong gust of wind hit the motorhome from the side, it would not be "flipped" out of that channel.

Some people have put an end to the roof inspections but applying EternaBond. I've never used it one any of the 3 Winnebago class A's that I had, but I hear it is a great product. If it holds up as they claim, it should be more or less permament. The part number that I posted earlier is the correct material for unpainted WI roof to sidewall joints. It is their latest (2002) information and I would venture so far as to say some of those guys at WI customer service haven't read it themselves, and are saying use silicone. I wouldn't use silicone. Silicone sealant is not a very good adhesive, and should not be used for the roof. An elastomeric adhesive/sealant, which is an excellent adhesive, is what you need. If applied to clean and dry surfaces, it will bond tenaciously for years, and your 6 month inspection will only serve to reassure that all is well. There is also another product, made by 3M, and found in boating supply store and Home Depot and Lowes, called 5200, that I would use as a substitute. It is bright white, and when cured, is permanent. It will even cure under water.

I like WI motorhomes, even with their inspection requirements. Overall, I think they are a good design, well build, and provide reliability and longevity. All things considered, I still think they beat the others for the money.

CaptBill, great info. Thanks for the drill down on roof/J channel cut away. Really helps to understand the dynamics of the topic.

I just want the viewers of these posts to know I really love our Suncruiser and that I'm not bashing our fine products. I know some people just get their cackles raised anytime you say something even slightly reflecting a critique of the products.

For me personally, I always raise a red flag when I see things like 6 month inspection' or '10 year warranty to original owner', etc.

Too often companies will use these simple tactics to limit liability. It's an inexpensive way to fix their exposure to a potential problem. As you clearly pointed out, what is covered by the 10 year roof warranty would exclude any failures here due to the seal, so this does not apply in this case. Good point.

If/when we need to address the J channel sealant, I think we will use the EternaBond and do it once and for all.

Have a great weekend.

Jim
