That Milwaukee caulking gun is the bees knees !

You're right about the membrane being on top of the front and rear walls.

Excellent job! You can tell the workmanship is far superb than when buying a new RV.

Hey James. As a licensed residential and commercial building inspector, prior to embarking on my career in facilities maintenance, I 100% agree with your reasoning and application of the roof membrane to front cap transition. Nice job. I can also relate to jobs taking a little more out of you as we get older, lol.

A trick to fill those "patch" crevices a bit better is to take some sawdust and mix it with some wood glue (super glue works too). Then you let it cure and sand it flush with the rest of the surface.

James, I’m not an expert at RV’s like you, but I totally agree with the roof membrane over the caps and your explanation as to why the factories do it the other way. It took me about 2-3 seconds to figure out the AC clamp it! Good one! Hope your next project is not a roof! We can tell you are getting tired of doing them. Best wishes, Kevin

James you always do quality work ! The information you give us is Honest and experience ! I wouldn't doubt what you say about how to do repairs !

by the time i have watched all your repetitive roof jobs i should be a pro come summer when i have to do mine. lol

Totally agree with the way you applied the membrane, just like putting roof shingles down.Does not make sense from the other perspective as we both know what water likes to do, take the path of least resistance and flow. Great job, and video 👍

Totally agree with your thoughts on overlapping the PVC over the front and back. Smart

Far from wrong !. Much better way to do front and rear caps. Great professional job as usual.

My kind of worker. You take pride in your work and no short cuts. You deserve every penny you get. Well done.

Water is a lifetime issue 💦 Thanks for your work today 😎

Way to go James. Very good tips for the vents, thank you. I agree with your rant and am always impressed with your work. Happy trails!

I really like your big fan that you had on the roof. I use the exact same one in the house and in the shop. Great job on your roof replacement.

Correct me if I'm wrong but it appears that on the front and rear caps the butyl sealant sits between the trim and the membrane creating a water tight seal but no sealant sits between the membrane and the front/rear cap metal leaving a major weak point for water intrusion. The same issue appears to be present in the corner trim at the joint between the top of the cap and the sidewall where the membrane was left to overlap. Bo butyl sealant was applied between the membrane and the cap/side wall joint. This application seems to rely entirely on the self leveling sealant to prevent water from entering between the membrane and cap metal. This is particularly concerning with the potential for driving rain into that area while driving down the road.

I totally agree with you. Recently I was putting a new roof on my YT and thought their way wasn't right and did it your way then I saw this video and was very happy to hear you do too.

This will help me greatly when I replace the roof on my 97 NASH next year…thanks for sharing your knowledge and techniques James. Very appreciated 😊

Great series of videos on this job. Extremely useful. Well done sir!

Great job James!

Great work as always, James!

Nice job James looks great.

27:00 you just helped me so much. I was trying to figure out if I should get a tinted or a white max air fan.

I am in the construction industry and yes, you are totally correct. When roofing just look at shingles, you don't start at the top of the roofline, you start at the botton so the water sheds from the top down. Thank you for your videos.

Nice work James!!

Thanks for another great video

Excellent explanation and job WELL DONE!!!

Excellent work James. This one was a doozy of a summer project°

Super nice work James I agree with the way you did the roof

I learned a lot and watched this entire series. Really good videos and explanations. Thank you.

I’m curious, what is the usual life expectancy of the various roof materials that RV manufacturers use?

Nice job as always !

Great sensebly done job,looks great.

Another great video. 70,000 too, congrats 👏 100,000 by the end of the year commin up!!!! 🍻✌

Thank you for a great explanation of how to do this project. I’m sure I will be referring back frequently as I start my roof replacement. And yes I agree on how to install the membrane over the front and back.

Thank you for all of your Videos. The information Really gave me Alot of confidence going into a recent RV Purchase. First thing I did was get on the roof! Found that it was not maintained correctly for several years and had a small leak in one of the corners that the owner had no idea about. Thankfully the owner was sensible and realized my offer was reasonable considering the damage and condition of the roof. Thanks again to your videos I had confidence in tackling repairs. I'm fairly certain I was able to repair the roof the correct way and was able to save it before it was too late. (I got the screws to bite for the corner trim on the roof thus I'm confident the structure was not rotted away.) Thanks again! Also some confirmation on your over the metal theory... This is a 2013 Coachman Catalina Santara 272BH. I was surprised to find that the EPDM went on top of the rear metal of the rear wall. I really think that is what stopped the leak from being significantly more damaging. It was leaking through a couple of small screw holes, not just inside the siding just as you described.

Beautiful!!

Another amazing job bud!

Looks really good.

Awesome video Great work !!!

another masterpiece job!!

Not wrong , i do the same thing on all my foor jobs. Nice work

I’d wish I’d found your channel when I found my Jayco roof leak years ago.

Stay hydrated 🌊 Edit: If you're ever in Quartzsite, or have recommendation 😁

Great job.

thanks for making the video

Agree 💯 percent on going over the top of front and rear caps.

pretty good work I respect the way go right at it with just a ladder. Most places I seen do this type job have built in or movable scaffolding for safety around the rv especially if you're going to be replacing the front cab over

James, came across your video because I need to replace roof. Guess where the leak was. The front couple feet sloped forward and since the membrane was tucked under the fiberglass nose it filled the ceiling section with water and caused the ceiling paneling to sag. I will be replacing like you did. Makes sense. Think like water. Thanks for the video. Looking forward to you showing me how to fix saying ceiling paneling. It's in the bedroom so I was just thinking screws with finish washers.

nice job

It is because of the camera angle, but my anxiety level explodes watching you walk to the edge of the roof. It doesn't bother me when I do it, but watching others, especially with the camera view drives that anxiety, lol😂😂😂

I had the same exact problem when I did the 360 vent install on my camper. I ended up using the stock bottom ring and sort of hacking the whole thing together. It worked out fine but it's ridiculous that they just didn't make the bottom larger on the thing

NICE..Job SIR

Better than factory 👍👍

You are good 👍👍

Since you solicited comments, based on my knowledge of stuff (not RVs) I don't see anything controversial in your work. For example, the fridge vent, air will find everything that it can to restrict flow. So you have to be proactive. The only thing I'd do differently, if I could, run the roof completely over the side and run strapping about 2 inches down all the way around the RV. But that ain't practical. I look on that as another failing of the manufacturer. Another fine roof. Ignore the doubters.

Awesome!

I totally agree 💯

Super nice job. I kind of like the galvanized plumbing vent covers. For some reason plumbing vents seem to get bumped when cleaning or inspecting a roof, and these don’t get crispy after a a couple years.

Nice 👌

Love the job! Just figured that you being very detailed why u didn't go ahead and spruce up the A/C cover to finish it off to look professional too??

I like to durabond tape the front transition, the rear if there is room. If the screws do work loose they are covered. Sometimes I’ll do the same for skylights and fridge vents We don’t stock liquid butyl and sometimes the butyl tape doesn’t seem to compress on those

Proper job!! You remind me of billy bob Thornton 😂

Great

100% right on the roof, (think like water)

I trust your opinion more than the manufacturers. You deal all of the time with engineering errors. I have a fifth wheel that has a macerator that I have never been able to use because of poor engineering. The dump valve for the macerator was installed in a position that it requires it to be pulled inward toward the middle of the trailer. I’m 73 years and have knee issues so o really don’t want to get down and crawl under it to dump my black tank.

What is your opinion on using stainless screws? I am renovating my dad's old 2001 Prowler travel trailer he gave me and I am going to need to replace all the screws holding down the trim pieces. The existing ones are completely rusted away. I figured if I spent a little extra on stainless screws, I would not have to worry about that happening again.

Excellent video series on this PVC roof just in time that I was doing one on a camper. I love your electric chalk gun, oh my how many tubes of self leveling sealant did you go thru? My kit came with only 4.

Totally agree I am just an old maintenance man

Really appreciate you posting these kinds of videos. Giving me the confidence to replace my roof membrane. My roof is 8 ft wide (single sheet osb laid across from camper sides). Is 8.5 ft wide replacement roll going to be wide enough or should I go with 9.5. Sorry if you've addressed this before. Thanks again.

great video! anyone ever tell you you look a little bit like Michael Biehn?

excellent tips for the DIYer, But, yea, I would have James do the job for my mental satisfaction knowing its better than factory original, especially if it's a Winnebago.

Do you know if the fiberglass roof on the 2012-2019 winnebago aspect/cambria is the same "side sealer" roof as that era of class A's?

Chasing a "road toad", too funny. Don't start foaming at the mouth!

Great videos! Such great tips. My question is when I tore off the old roof the sticky adhesive residue is still there. How do I but on the new with it like that?! So question is do I need to somehow remove it. Sanding doesn’t seem to work?

Agree with the shingle style of install. I need to reattach the track for a interior sliding door, how long of screws would you recommend? 2005 safari class A motor home. Thanks keep up the great videos.

What adhesive do I use on a felt backed TPO roof? It is being glued back down to the original roof decking on a 2009 Rockwood 2501SS. Thank you Sir. I really enjoy your videos! Keep them coming.

Good morning! Love your channel and watch it as much as I possibly can. I know you’re a roof expert and I have a question I live locally in Prescott Valley and would be willing to take it to you. A tree branch did some damage on my roof and the dealer is suggesting a new roof. I’m thinking a patch would be just fine and I’d probably rather have you do the replacement than the dealer I emailed a couple pics. Patch or replace? Your input would be greatly appreciated and thank you for your time in advance.

Great video James as always. I do have a question though. What keeps the membrane from tearing at the corners where you cut out for the ac?

Hey James, watching your videos I believe you are probably one of the best if not the best repair guys in the industry you’re very explanatory and it really helps people like myself understand how these trailers are actually built however, I’ve yet to be able to find any information on how to get a hold of you can you provide an email or a phone number for the people Who would like to do business with you? And also give us an idea of how much a standard roof replacement would cost with out structural damage

Thx for the video might be laying down a new membrane in a couple weeks. We sealed our Rv roof with Henry Tropicool (Silicone Roof Coating). Roof looked brand new for a few days until the silicone in the coating started attracting every single dust particle in Az. This stuff is a dust and dirt magent. Do you have Any knowledge of this stuff and know if some type of wax etc. could be used on top of this to keep the dust and dirt from attracting to it?

Great video, as always. How do you recommend terminating those roof/ caps again?

Would you recommend doing a membrane roof top on an enclosed trailer flat roof. I do have plywood fully above the supports pretty much like a camper. Also would you use any sort of tape to cover the edges before covering? Thanks

i found this channel while trying to understand RV 's better and though I can see that you don't look like you are in the RV business perr say I don't suppose you could point me to a couple good places around Arizona that sells used RVs would you

You should change your name to AZ, RV roof expert. Lol. I’m just playing.

Thanks so much James loved the video. James I have an 2007 Western Alpine Coach do you know if it would still have a OBD 2 plug ? I have looked all over under the dash but can't seem to find it ? I did not know if you would know the answer to this or not . Either way thanks anyway. Jeff

Wow great channel, just subscribed, if you don't mind I'll ask you a questions because no one else seems to have answers. I have a 2019 Jayco Seneca 37K. 39' long Diesel. Freightliner SV2r chassis. Rides like a gravel truck, can't type for sure while wife is driving and even texting on phone near impossible. put over 15,000 miles on it. had freightliner test they said its just right this thing looks like a million dollars and rides like a garbage truck. any thoughts on smoothing it out?

Beautiful job 🤘🏻 I know it is different on every RV, but what’s the average cost to install? (New membrane and minor plywood replacement on a 37’ toyhauler)

Is there a reason why you wouldn't use the sealant under all the flanges instead of putty tape? Is it simply cost? For a job that size, it seems like cost would be negligible.

That fridge vent looked like it just had some screen over it. Is that right? With bare wood being seen through the screen? That can’t be good can it?

Thanks for all this! Getting ready to replace the original rubber roof on our hand-me-down 1998 36' Fleetwood Pace Arrow. Is there any value to TPO over PVC though? You kinda made it sound like a supply chain compromise.

Do you put any adhesive under the membrane on top of front cap? It would worry me that small imperfections on top edge of front cap could allow wind driven rain (while driving to get under the membrane. Maybe a little butyl sealant from a tube under the membrane??

Thinking about putting truck bedline on when I get my new RV But haven't decided yet depends on what the rv tech will sayabput he is in not far from me in town What he says about it If that doesn't work out that I may just go with rv armor And have them come out and do their stuff

What brand of cordless stapler and size/type of staples do you recommend for EPDM roofs?

i should have james redo my roof on my 2007 32’ toyhauler. it’s got some rot on right rear corner

Thx for all your tricks. What do you think about the rv sealant roof tape insted of lap sealant ?

@ 17:55 sorry to keep bugging with the same question, why not Eternabond tape?

if a unit is parked under a quanset hut like you have there so its not exposed to the sun or rain or snow etc how long do you think that roof willl last if they are not going anywhere no travel just staying parkedd ??

Great video....at the same time I asked the question why install that garbage roof that will fail again in a few years with the same material instead of a more durable fiberglass rood? was this an insurance job? always enjoy your videos and why are you tipping these AC units upside down? those compressors are not made for that and will enhance failure down the road as the oil isnt meant to flow up into the head unit of the compressor, and your advice on a PPI is golden

What is the average cost of complete roof replacement? I have a 2017 Lance 1995. Thank you.
