How to Repair and Seal a Rubber RV Roof - 1998 Bounder Motor Home

[@simbadurio444]

Wow, looks really great. Good job on the video too. Was really soothing to watch. I looked up the price for a gallon of this stuff is only $62 at Walmart. I was looking at crazy seal, but got a quote of over $2k doing it myself. I know there are levels to this roofing thing. But this seems like a more viable solution for me right now. Thanks a million!

[@Liveforwhatyougive]

Nice job! Just watched your video while waiting for my first coat to dry. 👍

[@natomblin]

Thank you for taking the time to make this video. I have a 1997 class C motorhome with a roof that looks very similar to yours before the sealing and coating, and your advice on products and applications are appreciated.

[@Claps1775]

I got a 2000 Bounder 39Z that I need to seal the roof bad. Weather in Washington is getting a bit more wet. Thanks for the video. I have some damage I need to fix on long the edge where the roof wraps down the side.

[@glennwisse6271]

Looks good. Nicely done. That should help prevent future problems. Your slide out cover does indeed need help. You can see how water collect there. You’re off to a great start.

[@Buckwsr]

Thank you, Glenn!

[@tdubs5128]

How has it held up since you applied it? I need to do mine this summer.

[@charlesfroeder1035]

Just a thought here. I used a different elastomeric coating. However most leaks come from the edge where the rubber roof bends over to the drip edge. Water leaks through there and down the outside of the wall leading to soft spots on the floor. You don’t see it leaking and yet it is and causing damage. I washed my roof with the “Reliable One”, then used alcohol on the edges and then applied a 4” Dicor tape with a cloth backing along the edges full length. The cloth backing is then coated with the roof coating while doing the whole roof. Did 3 coats. We have had some bad rain storms here and this combination of steps has proven itself to be worth the effort. Also used self leveling caulk on all openings. It’s an inexpensive way to get more time from a worn roof.

[@Buckwsr]

Thanks, Charles. Good info and tips!

[@talk2genx]

I started the same project on my 1989 Damon Escaper 27' Class C this morning. My roof is in pretty decent shape for being 30 years old. I found a couple of small holes and I will be sealing up around the vents, etc. I am also going to be using the Heng's Rubber Roof Coating. I think the key is to not fall off the roof.

[@Buckwsr]

Good luck with the project. And please don't fall off!!!

Just did this today on ours. Used white roll on flex seal. Hope it’s good stuff

[@GrowingState48]

Great job. I'm seeing this 5 years later, so I have to ask how the heng's has held up for you over time. Would you still recommend the product for someone shopping today?

[@jennifergulley9285]

How long is that motorhome and how many gallons of that roof coating did you use on it? Thank you

[@outbackbuildingsplus2964]

My concern with siliconized and liquid rubber applied directly to another rubber based product is that it will just peel off; that, maybe water can find a way between rubbers. I wonder if a water based elastomeric coating followed by the rubber coating like you show would work much longer?

[@visamedic]

Well COVID took me out for 11 months last year. I did get my awnings done. The rain has finally let up here, and I’m getting ready to get this done. I’m gonna go with the Flex Seal. Your roof looks just like mine, the wear and color. Every time I go to clean it, this black water keeps running off. Is there a product that’ll clean it better. It’s almost like black chalk. Or do I have to keep scrubbing with dish soap or Purple Power it until it finally is clean? 6:11

[@Buckwsr]

I don't know really about how much scrubbing to do. For me it was December, and I was up against the cold weather. I think I gave it pressure washing, let it dry, and then applied the coating.

[@visamedic]

@@Buckwsr Hmm. Im kinda racing the warm up. Were getting into the 70’s now. I guess I could just give it a good cleaning, let it dry, and coat it. Again. Thanks for the video

[@UnblockedOne2]

thanks for this. I just bought an RV. I didn't get a chance to inspect the roof when I bought it. thankfully, it never leaked.

[@Buckwsr]

Good luck, and enjoy your RV!

[@meredith2277]

How has the Heng's held up for you? I am considering it as I like the simplicity of one part application.

[@robwarga3491]

I work on these for a living. The proper way is to remove the old sealer best as possible and replace with new dicor sealer. The best way to do front and rear cap is to use the bear Bond tape or other rubber roof tape. I'd prefer using the tape over the cocking wherever possible seals a lot better and a lot cleaner job. Either or we'll do the job but I recommend trying to remove the old sealer first.

[@Buckwsr]

Thank you for the good recommendations.

[@davidlang1804]

Rob Warga How do you recommend removing the old sealer? Some of that stuff is pretty thick and I would worry about cutting the roofing.

[@robwarga3491]

Use a good quality putty knife remove as much as you can and as smooth as you can. What you can't remove take a good wire brush and scuff it up and go over it with the dicor. It's not as bad as it might look goes pretty quick. Be careful along the edges for it is self-leveling and will follow down the sides. It's not a quick job but it's painless. From the factory my opinion they don't apply enough dicor so I would apply a little extra when putting back. Have a good day and happy seal ing.

[@davidlang1804]

So Rob, ir you are refinishing a roof from a 20 year old motorhome, would you seal the caps with a permabond type tape and then roll on the new roof finish? Also, what about where the roof meets the sides of the RV? Is that a different sealer? You have been very helpful and encouraging. Thanks

[@JM-nh8yp]

The videos put out by Dicor themselves show them applying it directly over the old sealant. As long as it isnt peeling off, they recommend cleaning it and applying their product directly over the old.

[@DailyLymeLife]

Did you scrape off the old caulk & seals before re-caulking or did you just brush & clean the existing caulk & add your dicor over the existing?

[@Buckwsr]

I removed any caulk or sealant that was loose or peeling, but left any that was still solid and intact.

[@DailyLymeLife]

@@Buckwsr Thanks so much! That’s what I did.

[@durangodave]

how is your roof holding up with that product so far? one thing i would add is that the black from bare rubber comes off and gets everywhere so wear gloves and clean shoes afterwards.

[@Buckwsr]

If you check out some of my other RV videos, you'll see I switched over to FlexSeal Liquid Rubber. I like it a lot better. With the Heng's I felt like I had to re-coat the roof every year! But my roof has been completely leak-free since I did this job.

we have used this but like the rvroofmagic better. goes on very thick and our shop has never had a call back on any units it was applied on

[@melrobinson6919]

So for how long have you been using the RV Roof Magic? My 2000 Terry TT has the Alpha roof and the RV Roof Magic is one coat, no primer needed. The Liquid Roof product requires the primer on an Alpha roof, which would be nice to not have to do, so I'd like to know if Th Roof Magic really lasts for, say, 5 years or better. Thanks.

[@jajjohnson]

Coating the clean black rubber is okay?? Mine is in perfect shape but completely black rubber..they told me you cant seal over the bare black it needs a new roof..

[@steelpix]

Buck, how has it held up? How many years and did you have to recoat?

[@IanoftheRVin]

Excellent video. Just purchased a 1999 Fleetwood Tioga 29Z. While the roof does seem solid, it has leaked around the skylight. The previous owners put a variety of tape sealants over most of the edges and caps. It really is a mess up there. Although the original roof is white, there isn't any white left. Its all black and chalky. Plus there were some small rips in the membrane. I've been trying to convince myself that I could get away with a roof coating. But as I'm typing this I realize that that isn't going to work. I'll need to install a new membrane. Any suggestions you have for products and hints to get this accomplished would be most welcome.

[@Buckwsr]

Thanks for the note. I did not have to go to the extreme of replacing the entire rubber roof. Since making this video, I have switched over to Flex-Seal liquid rubber coating. With the Heng's, I felt like I had to re-coat the roof every year.

[@marvinelvis2989]

Why did you have to re-apply it every year? Was it because the black would bleed through?? Did the Hengs stay securely attached?? Fixin to do all this myself as my roof is completely black now. Zero white left on it!

[@IanoftheRVin]

@@marvinelvis2989 not sure if my previous reply went through. I ended up completely redoing my roof. The membrane was in such bad shape. I also had no idea what products the previous owners had used. Some coatings will stick to some products and not to others. For Peace of Mind I went right to the decking and started from scratch. It was easier to do than I anticipated. The old membrane came up VERY easy. Which told me the glue that was holding it down was degraded. I did it all by myself, which (if you're considering replacing the membrane) I DO NOT recommend. I also went ahead and replaced all the trim with . As the original trim didn't have gutters. You can see all the work I did on my channel. Also feel free to reach out with any questions.

You don't show any cleaning step. Just curious, did you try to wash this roof before sealant? If not, has there been any delamination of the sealant? Normally, surface prep is the key to good adhesion.

I would recommend some kind of sealant, like the Dicor self-leveling roof sealant or other type of caulk. I don't think the Heng's alone would seal those seams sufficiently.

[@talk2genx]

For those of you contemplating a similar project, I would say it took me 3 hours to clean the roof, about an hour to do the Dicor Self Leveling Lap sealant around the vents and misc, 1 hour to apply coating with a brush around the edges and vents, and another hour to roll the two coats. Once you start rolling, it goes fast. So total time was about 6 hours over two days. I used an electric power washer to clean the roof, and then a RV long handled brush to bucket wash it. I did NOT use a dry detergent like Tide powder, but I should have. I had already scrubbed it with Dawn Platinum and was too lazy to go do it again. My guess is Dawn is not recommended because it is not the right kind of detergent. The Dicor self-leveling lap sealant is great. You will use about 1 tube per standard 14" vent. I had 4 tubes and it was not quite enough to do 3 vents plus the other smaller tank vents, etc. I would suggest doing the lap sealant a week before coating the roof if possible. I only waited 1 night, and it was fine, but still fairly soft. Some people say do the lap sealant after the coating has cured, but that seems backward to me. Either way is probably fine.

[@talk2genx]

Dawn may not be recommended because it contains polymers (copolymers) that could affect the coating's ability to bond with the roof material. The powdered dry detergent probably doesn't have this problem. Use the powdered detergent.

[@KBS117]

I use a 50/50 mixture of bleach and purple power.. it removes everything, even old crusty roofing.. I even use it on the sides.. it will discolor old plastic stripes.. but, you don't have to scrub nothing...and your new sealant has a clean surface to bond to..

[@sydneybird116]

TSP Trisodium Phosphate in a bucket of water works great as a non-filming easily rinsed cleaner with a soft carwash brush, but I didn't have any mold being in the AZ desert. Power washing could damage the roof and drive water where you don't want it, so I just used a low pressure rinse. I used Henry Tropi-Cool on a TPO roof.

[@leagamillo1254]

I hope you have better luck with the Heng's than I did! After about a year & a half it started peeling off my roof! I have a 2000 Bounder & just spent 2 days power washing & scraping that crap off! I'm going with Dicor EPDM 2 step system this time. Darn Heng's sure caused a lot of work for me!

[@Buckwsr]

I think originally I used Heng's because I did not have time for a 2-step process. I wanted to coat the roof quickly and without delay. 6 months later, I re-coated the roof again with Heng's. I will probably re-coat it on a yearly basis. The reality is that an RV roof requires regular maintenance. Let me know how you make out with the Dicor. Thank you.

After a lot of research, I'm gong with rvroofmagic which is a one coat coating guaranteed to be good over any type of roof including the Fleetwood Alpha roof that my 2000 Terry travel trailer has.

Hoping the 10 year warranty means something on the roof magic...lol

My 2001 31W Bounder has a TPO roof. This Summer 2021, I gave it two thick coats of Henry Tropi-Cool. It took the entire 4.75 gal bucket. I also coated the exhaust vents and the shower skylight for protection and to reduce the heat coming through. One month later I was hit with a 30 minute quarter-sized hail storm that shredded the topper awnings, broke the exhaust vent lid in the kitchen (smoke colored translucent plastic, the white one in the bathroom with Tropi-Cool coating survived), and cracked the shower skylight. The AC covers would have shattered but I replaced them when I coated the roof so they were fine. The roof has some significant dimples, but the Henry coating saved my roof from tears. There are a few 1/8 inch "chips" taken out of the top coating layer I guess due to the hail not being smooth balls, so just in case I plan to coat with one more layer of Henry Tropi-Cool. With the awnings off, I also coated the slider tops. Without the awnings I got water soaking the carpet in the RV at one corner of the open living room slider. To "fix" the skylight, I just lathered on thick coatings of Tropi-Cool over the cracks hoping that I will not have to replace the skylight.

What an experience! Glad the damage was not beyond your ability to mend thing up. Good luck!

[@randallgalleano6489]

How long is that motor home and how many gallons of rubber roof coating did you use?

[@Buckwsr]

2 gallons of the product were enough to put two coats on the roof of my 34 foot RV.

[@phillipbruce5936]

How long is your RV and how many buckets of Hengs did you use?

[@Buckwsr]

The RV is 34 feet long. I used about a gallon and a half to apply two coats.

[@phillipbruce5936]

@@Buckwsr Thanks for letting me know I have a 36 footer so I think 2 to 3 gallons should be more than enough. I enjoyed your video.

This is one of the best looking jobs I've seen on KZbin. I've got a 39' class A with a TPO BrightTec and it needs replacing or coating with something like this. I haven't heard of this grade Hengs before. How is it holding up so far. Again, it looks really good, very uniform and not splotchy like some I've seen. Thanks for posting this.

[@Buckwsr]

I did this job last december. Now, in August, roof remains completely dry and without leaks. I did recently paint on another coat of the Hengs since I havdenough left in the can to give it another coat. So.... so far, so good. Thanks for the note.

[@deanrising6577]

Buckwsr... Was that all with only one gallon?

[@Buckwsr]

@@deanrising6577 I used a little more than 2 gallons, I believe, in putting on two coats of the product. I had purchased 3 gallons. 6 month after doing this job, I used what was left of that third gallon to put on one more coat.

[@rickl6697]

@@Buckwsr After inspecting my roof for what I thought was an air pocket under the TPO roof turned out to be buckled plywood. After opening it up to see if I could maybe just patch in a piece of plywood, glue the roof membrane back down and use a liquid product like you did I found the damage went around the rear a/c on 3 sides, so now I'm in the early stages of taking off the entire roof. Only a few items left to remove(had 14 items which must come off before removing the 9 sheets of plywood), then the termination bars and plywood. At 16 years old it didn't make sense to do a partial re-roofing job on the coach. What fun!

[@markgarrison6035]

How did that sealer do did it fix the leaks I want to try it on mine just bought a 2000 coachmen they said had no leaks but just had a real good rain and found 2 leaks

[@Buckwsr]

It's only been about 3 months, but so far perfectly dry, and we've had a fair amount of rain this winter, so I'm feeling pretty good about it.

[@russkester7006]

Looks good.

[@diymaniac876]

I've read most of the comments, and most Google Reviews as well, and this Product seems to have about a 95% Good Rating, I Just Ordered 3 Gallons for our 35ft, " 30sq Ft Roof " 99 F53 Fleetwood Flair. It seems to good to be True, and you know what is said about That, but I'm rolling The Dice, as This thing is going down the Road after this Year, so If it Holds up 1 Year, then I'll be completely Happy, even if I Have to give it 1 Re Coat Goodbye...lol I Have Dicor Lap Sealant for The Seams, and Rounded Edges ETC, But I Am Really Thinking about using 4" Eterna Bond on Both Sides and The Termination Caps, along with 1 small Hole near the Skylight. So, just verifying some remarks, you only powerwashed this roof, with no scrubbing with powdered Tide ETC and it did not peel B4 you Switched over ? I know you said you switched because of seeming to have to re seal every year, but why ? Was it thin looking, with the black showing through, or what was the issue ? Thanks Kevin

[@Buckwsr]

I don't remember scrubbing the roof at all, just pressure washing. The original coating was pretty much all gone anyway. And I was in a hurry to get this done before winter, as it was already December. I think I had to recoat every year Spring because after a year in the elements it looked all dirty and discolored, sort of like a flat finish paint that shows all dirt marks. But I think that between the dicor sealant, the 4-inch tape, and the Heng's, your roof will be dry and nice and good to go! Some people confuse the Heng's with Henry's (available at home depot), but they are completely different products. In the end, I'm glad I switched over to the FlexSeal liquid rubber. Way better, and no more annual recoating. But of course, a lot more expensive. Good luck.

[@diymaniac876]

Did you have any of the old stuff flaked up everywhere ? I'm just starting into this, and MAN I HAVE A MESS, I've been scraping, using a Wire Brush ETC, this thing is REALLY BAD.

[@stevemizar4143]

Did you wash your roof first?

[@Buckwsr]

Yes, I pressure washed it a few days earlier.

[@ze_german2921]

how many gallons did you use?

[@Buckwsr]

Less than 2 gallons to put on two coats.

[@my74vette]

Nice job on your roof job. I do have a question. I need to reseal my rubber roof. My concern is there alot of peeling from a previous seal. I just bought this MH and my guess is the previous seal a long time ago. I worked on one side using a nylon brush with Simple Green. Some of the peeling came off but most did not. Did you have any issues like that? Thanks for any information that you can help me.

[@Buckwsr]

Hi Robert, I do not remember any actual peeling, per se. I would just scrub and clean off what you can, maybe try a pressure washer, and then re-coat. Expecting all the old coating to come off may be too frustrating, or even impossible. Just my two cents. Good luck.

[@my74vette]

@@Buckwsr Thanks. How many gallons of Heng's Roof Coating for your MH? Mine is a 94 Fleetwood Bounder 34. I was working this afternoon. Lots of peeling. I went up about 7:30 tonight. I don't know if the peeling sticked down but it looked much better. Maybe magic!!! .Thanks again.

[@Buckwsr]

@@my74vette I think 2 gallons was more than enough to put on two coats.

[@nfinance2]

I see so many reviews that Heng's will peel on this rubber roof without a primer first. You stated in comments that you already recoated the roof again. Was it peeling? Why did you need to recoat? I'm thinking of going with the 2 part system from EPDM Coatings. I want it to last years so I keep watching reviews. Obviously Heng's is less expensive but some of the peeling issues are just terrible.

[@Buckwsr]

No, mine never peeled to this day. I recoated mostly for additional protection and to make it look clean and white again. But it has never peeled.

Two gallons allowed me to put on two coats, and have some left over.

[@hatteraslabuf]

Did you get that Heng’s from the guy in Pennsylvania who sells dented cans, at a huge discount?

[@Buckwsr]

I think I bought it from an ebay seller....but it wasn't cheap. And the cans were just thrown into the box with pretty much NO packing material. I think they got all dented up during shipping.

[@hatteraslabuf]

I bought four cans from this guy in Hazleton PA. If I recall, he sold them for about $35 a gallon. They were discounted as they were dented cans and came shipped in a cardboard box, each gallon was in its own separate plastic bag to prevent leaks. No problem whatsoever with my order.

[@joebidendidthat5121]

Bought 2 cans from Amazon $65 per gallon can for Hengs. I got dented cans with no packaging. Can’t believe they did not leak. My local RV dealer wanted $115 per can of Hengs!

[@abrs100]

Great video! My 2002 keystone Montana has a roof that has probably never been done. My question is there are several places where the old sealer is peeling off. As a former house painter I know to remove peeling paint. Is this how I handle the peeling sealer? Thank you!

[@Buckwsr]

In my opinion, sealant that is still intact around roof protrusions should stay. Anything loose should come off and be replaced/re-sealed.

[@abrs100]

Thank you so much!

[@jamesmcdonald3672]

Hi it’s 30 ft 95 sea breeze that is leaking at front

[@maragitacruz2124]

Theres not a nice wash to remove that old mold ? I think paint in the top of the old mold is gonna be good fpr maybe one year, after that mold is gonna explote again.looks a good job on the reseal,but maybe with a nice wash first can be a better job.by the way thanks for share.

[@Buckwsr]

I absolutely washed the roof thoroughly first! The black color is not mold, but the original rubber roof. Most of the previous coating was completely gone....

[@KBS117]

I use, 50/50 mixture of purple power and bleach. I spray it on a dry area, and scrub the loose black powder off with a brush.. I then power wash... Keep the sides rinsed, as that stuff can lighten your pin stripes, if allowed to dry on it.. any water, weakens this stuffs ability to work.. I mix it in a pump up chemical sprayer.. it kills all mold, and leaves a squeaky clean surface for the new roof to adhere to.. it is a killer mixture for removing the crud....

[@gwhittaker]

Thank you for doing this video, I really needed it. It will be three years in a few months, how did the Heng's hold up?

[@Buckwsr]

It is holding up very well, nice and dry. But I have recoated it since then, just to keep it well sealed and looking good.

[@WildlifePatrol]

Should I just put the lap sealant over the old stuff or should I try to remove it? Seems really difficult to remove!

[@Buckwsr]

I would not remove any sealant that is still intact. Just whatever is lose, broken, or perhaps cracked. Apply the new sealant directly on and around the old stuff. That's what I did, and it's holding up perfectly.

[@billtrefts9238]

It looks Great! I have the Heng's coating and hope to apply it this weekend. Did you only brush 1 coat on the edges? A thick single coat? Or did you second coat the edges when you did the overall 2nd coat?

[@Buckwsr]

I think I "cut in" twice with the brush before using the roller, if I remember correctly. Good luck! And thanks for watching the video.

[@talk2genx]

I used 1.5 gallons of Heng's Rubber Roof Coating to give my 27' Class C two coats. The directions on the paint can say to use a mixture of strong powdered detergent (e.g. Tide) and water and scrub the surface and rinse well. The can says to allow 4 hours between coats -- that was about right for a sunny day about 78F with 35% humidity. Normally it is much more humid in Iowa , but I got lucky.

[@Buckwsr]

Hey, thanks for the report. Sounds like the weather was perfect for the job. As you may recall from the video, I did my roof job in December (in NJ). Not ideal, but I had to get it done.

@@mtemp208 It may have reached 50 degrees as a high that day, but surely it was not that warm continually over a 24 hour period. I knew the can said 50 degree minimum, but I decided that the urgency of my situation was more important and I simply had to do the job without delay.
