Hi yall. I am an aeronautical mechanical engineer and I was looking at the installation of the TPO to understand a bit more about it since I plan in Buying a motor home that has the system. When I got to the section 6:30 min, installation of the TPO front and rear termination I got astonished by the installer. Here's why: The reason to install the TPO under the cap is shown on the engineering drawings. When you pull the RV in the rain, the chances of getting water under the TPO are minimal, since the butyl tape, cap, another butyl tape, and lastly the trim holds it down. Similar to if the RV is stationary. On the other hand, the back is inverted, and the TPO goes on TOP since it makes it difficult for the water to slide under it when pulling at highway speeds. I take that those aerodynamics classes are tough only on the aviation side? The bottom line is, that the TPO must be under the CAP to avoid the wind and water from entering under the TPO and damaging the underlayment. Another point, the TPO is terminally compliant, meaning, you can shape it with a help of a little butane torch. Lastly, the TPO should be rolled pressed, not broom smoothly. The pressure helps the two sides bond. Dang it, why did I watch this video. Looks good on the end, but it is not kosher.

[@AZExpert]

thanks for your input. I look forward to your installation videos to learn from.

[@wildwoodtop]

Mackieviczusa Make me a sandwich! Ham and cheese please Thank you

[@jeepsnthings565]

That's exactly what i was thinking. So rain doesn't get forced under the tpo at highway speeds. But in reality RVs are parked 99% of their lives. So rain water runs down the cap not up.

[@cwkhonda]

I actually commented on the pro and cons of this issue before I read yours. basically either works. however it all boils down to the maintenance and inspections. do nothing and you'll be paying a high price no matter what to fix it. inspect your rv roof at least twice a year and you'll be a happy camper for a long time.

[@cwkhonda]

I see pros and cons to your method of the membrane termination at the front cap. Going over the front cap makes sense. If the molding fails or the maintenance lacks. Then any standing water will run over the membrane, under the molding and over the front cap ( no water intrusion into the front cap and down the inside of the front wall. However. I get you mentioned that you've seen the molding loosen and lift. But if that were to happen. Then air can also get under. which means if you are driving and the butyl tape is compromised. then the membrane will or could balloon. I guess it's a matter of which damage will be worse. Basically it all boils down to the person/s that should be maintaining and inspecting the roof. If regular inspections are done. either way works. Another possible. If there isn't an issue, just driving often, the air pressure at the front molding could find its way under the membrane. I haven't seen this, but if you are going to run the membrane over the front cap, what about this order. Front cap, butyl tape, membrane, then butyl tape and last the molding? seems like a lot of butyl tape. maybe butyl caulking? Your thoughts.

[@AZExpert]

Air does not force its way into the seam properly installed, factories are just lazy and install the roof first and then the cap. Wind comes at speed from all angles including the side and we overlap the sidewalls too.

[@keenankealy1741]

The reason the install the too under the front cap is so when the front trim comes loose like you said it will, the wind won’t grab the membrane as easy and cause more damage. I’m with you though I hate the way the factory does it

I’d figure you would have scaffolding to slide up to the coach on both sides to make it easier to pull the roof in both directions. Just a though. Great job.

I have a roll around scaffolding which was used in the video, but roofing is not my primary service, so I can't keep the shop setup permanently with a walk around catwalk....it would be great though. Thanks!

[@tomgolden8996]

It goes under the cap to stop rain from entering when the rig is being towed. 55-65 mph rain storm. It will leak if towed in the rain.

[@AZExpert]

That's an interesting and confident idea. It would be very impressive for the drive to push rain through the lap sealant, butyl sealant, and pass the double rubber gaskey seal made by the molding trim screwed down. I've never seen this pop up in +100 roofs. When instructed by the manufacturer, they state the instructions are mostly general guidelines and leave a great deal of preference to the installer based on conditions. I suppose some owners may not mind paying $1000 extra to remove the fiberglass front cap in order to tuck the roof "properly", but I don't see a benefit to risk breaking the cap. I would also guess every rubber roof should leak profusely if a driving rain is coming from behind then? I can also say, much like a shower pan liner, it's better to bring the membrane up the seam so standing water does not make its way under the front cap. Thanks!

[@rickl6697]

That's what I thought too. I'm replacing the TPO roof on our 2003 Newmar DutchStar but when I removed the TPO at the front and back it is on the top of the fiberglass cap, just like AZ did. The termination bars are on top of the front and rear cap. I had no leak problems there whatsoever. Our leaks were mainly at the a/c mounting bolts which were all on the outside of the 14x14 a/c gasket and a small amt at the tv antenna and shower skylight. While rv roof install's installs looked good I couldn't believe some of the orig sheathing he left on there and just glued 1/8" or 1/4" luan on top of delaminated discolored wood. Also, if you need to change out a vent you're probably going to have to take it back to him to have it heat welded, unless you have a $400+ heat welding gun and the ability to use it. (It doesn't look that hard but I'm sure if you did it yourself it would void his warranty). My nephew owns a large commercial roofing company. Plus the fact you need to take it back to him to be inspected each year.(Good idea if you live or regularly travel near his neck of the woods.)

The roof on my 2022 Thor Hurricane 34J has a TPO roof and the lap sealant is full of bubble holes over the entire roof. The installer also dripped and tracked lap sealant all over my TPO roof from front to back and on top of my solar panel. It is my belief that the defective sealant should be removed and then revealed with good lap sealant. But what to do about all the spilled and tracked lap sealant?? Will any solvent remove the lap sealant off the TPO roofing without damaging it? What do you recommend? Thanks.

[@Tom-oq7cb]

Hello from Minnesota, I can't find any info on this and hope you can help me. I have a 20 year old Winnebago 37G motorhome with a filon roof and spider cracks from hail damage, no leaks yet. As you would know, the 20 year old surface is a bit rough that I think an adhesive or silicone would bond to. Can I install TPO over a filon roof? And if so, what would be the best adhesive to use. I would assume expansion and contraction are not a match. And, will an eternabond type tape stick to the TPO. If I could use TPO over filon, doing it myself, I could work/glue down in sections (working outdoors) pulling vents etc or cut the TPO around the openings and tape and dicor seal those areas. I'm also considering silicone Mule Hide or Gaco silicone... cleaned, all seams prepped with fiber tape etc. As your video's point out, I don't want to do anything "Stupid" haha. Other than picking the right silicone product (Mule hide has more solids than Gaco, is there a product you would suggest?) I have a handle on the application but am concerned if silicone is the right thing to do or go another direction like TPO. I can't do a full filon demo in my driveway by myself and 10k for a pro to do new filon is not an option. Thanks!

I would have a difficult time recommending any coating or membrane if all you have are some spider cracks but no tearing or damage. Filon can be repaired like fiberglass. Securing a membrane to the sidewall will be the most difficult part

Hey bro. Certified tech here from Wa state. Just curious, do you not need to put a thin layer of luan sheeting over the existing OSB first? I was just curious cuz that’s how we’ve always done it. I know things change quickly in our industry. So it’s ok to lay membrane over existing decking?

[@AZExpert]

It's my preference if the exisiting deck is not damaged, that overlaying paneling it mostly a cosmetic desire which can cause more issues with screw pops or bowing and twisting from the overlaid paneling. The glue will stick to itself of course. I personally, have not seen many membrane roofs without some comsetic defect from the deck, radius, or seams so I don't feel it's worth the risk or time.

[@dannywest9256]

@@AZExpert Can’t say the thought and logic have not crossed my mind, more than once. Not because I wanted a shortcut, but instead exactly what you said, if the decking shows no damage, why not? My biggest worry would be the smoothness of the membrane being laid. Working on one today I helped a kid with yesterday. He made the mistake of rolling from one end to the other lol. Didn’t even make it half way before he realized how crooked the membrane was. Make matters worse, he was cutting holes as he was rolling. So trying to peal and adjust while glue was tacky was a mess. I opted to roll the membrane out and fold it back half. Let it dry and redo today. Not really his fault. This company i started with not too long ago is hung up on techs doing everything solo. A green tech tackling a roof replacement on his own is a recipe for mistakes, I don’t care how smart he thinks he is, experience matters. Man thank you bro, God bless you and your team!

[@blah987t5]

Stupid question. Why don't rvs ever use real laid down fiberglass like boats do?

[@AZExpert]

Some have fiberglass

[@RVGuy613]

Going to disagree with putting the rubber above the front cap instead of tucking it inside. If water were to get inside there, that means that the molding isn't sealed properly. If that is the case and the molding for whatever reason isn't sealed properly at the front, while driving that will allow wind to get inside and potentially underneath the rubber material with no where to go. This can cause the rubber to lift, that is why they say to tuck it underneath the front cap. In my opinion, that is a worse issue than a bit of water getting inside the front cap. It is a good idea for preventing water from leaking in if the rear side of the molding isn't sealed, but I think the negatives outweigh the positives.

[@AZExpert]

I disagree and your situation doesn't happen. But I cannot explain how many times the molding comes loose and water is directed straight into the front cap causing extreme damage. They tuck it in at the factory because they're lazy and have the roof on before the cap, it's that simple. The rubber lifts, because the factory doesn't glue the membrane down correctly

[@RVGuy613]

You can disagree all you want, but you're still wrong. Whether you tuck the TPO inside the front cap, or cut it off beneath the molding, water will still find it's way into a loose molding, especially during travel. You're just adding an additional potential problem by giving the wind the opportunity to lift the TPO. Once water gets in there, you not only have water damage to the decking, but if that roof ever catches in the wind, it will pull away from the roof and possibly stretch the material if the circumstances are correct. A good technician is always willing to learn, and you said it yourself in the video, you don't know why they tell you to tuck it in. Now you know why, but if you're willfully ignoring the proper installation method then we'll just leave it at that.

AZ Expert Could a person put the membrane under the front cap with something like eternabond double stick in between, then heat weld a strip of TPO to the roof behind the transition so it overlaps above the cap, sealed with eternabond, butyl putty, and lap sealant? I do like your idea, in that an RV spends more time sitting in the rain than it does being driven down the road. I just wonder if there’s a way to do both (have membrane go under, and over the edge of the front cap) and if that would be a good idea.

[@AZExpert]

​@@JeffinTD Sorry for the late response. Half the problem with the instuctions to install the membrane under the front cap is getting the material under the front cap safely. Most modern RVs have mold formed fiberglass caps that do not allow for any clearance especially at the radius edge. To safely get under the cap, it would have to be removed and I do not see a benefit to needlessly remove a cap as they crack don't fit back on right or can be dropped and damaged. I've never seen rain driven through lap sealant, butyl tape and two to 3 ridges on the backside of molding.I have repeatedly seen the screws fail on molding where the membranes are tucked under the cap which then becomes a large gutter directing water into the front cabinets or wall. I just don't see a benefit to the ordeal, it's better to inspect annually. Thanks!

[@JeffinTD]

I see your point. The last RV I had the front cap was flat fiberglass. It does seem if a roof is going to have a soft spot, it is often along the front transition.

[@rickl6697]

Did you replace the sheathing too or was that the original from the factory. Regarding the TPO not being able to be stretched without damage, do you think epdm would be a better choice. Thanks.

[@AZExpert]

Careful prep work can be a real time saver sometimes. The sheathing is factory. Cutting the roof into small strips and sections and baking it in the Arizona summer sun, the membrane removed with minimal damage to the sheathing which was 3/8" OSB. If the sheathing is damaged than it needs to be replaced or overlaid, which adds greatly to the time a cost of a roof. EDPM/rubber roofs are a higher quality and thicker roof, but do chalk. I'm not convinced EDPM is better though. However, some roofs are so wide that TPO is not available only EDPM. Thanks!

In all fairness it looks like your install looks great.... just as good as new. You could put that coach on an RV lot and sell it to a happy customer. Unfortunately new in the RV world is substandard. If I'm paying for a roof that failed prematurely I want something better than what was on it. The video was great.

The way you installed the material at the front is completely wrong. It will allow rain to be driven under the roofing material when the trailer is in motion.That is why the factory installed it the other way. There will be no way to avoid water infiltration.

[@AZExpert]

However completely unlikely that is, it would be caused by lap sealant failure, screw failure, and failure to inspect annually. There is a very high cost to remove the fiberglass cap in order to tuck the membrane under it without damaging it or the cap. Moreover, it that was actually true every rear cap would leak in a driving rain that was blowing from behind the RV as this is the method the manufacture recommends at the rear. Thanks!
