RV Roof Maintenance and Repair
A leaky roof on your RV, whether it is a large motor home or a small tow-behind model, is the most destructive of problems faced by many owners. A small unnoticeable roof leak will gradually spread out to other sections of the unit’s body, walls, and floor structure.
This is why it is so important for an owner to visually inspect the RV's roof several times a year. The reason for this frequent inspection is because many units are only used a few times a year, therefore a leak may spread quickly with no one to notice the beginnings of a ceiling stain.
If your RV or camper trailer is stored under a shelter of some sort this is not applicable as your RV roof and rubber coating will last many times longer than a camping unit which sits out in the weather. Direct sunlight and heat may deteriorate the chemical compounds of many sealants over time, allowing moisture to eventually find the cracks in the roofing material.

Accessing RV Roof and Damage
The following tips will help you visually inspect your unit's roof for leaks.
A
small unit may be inspected without having to get on the roof and in
fact, it is recommended you never stand on an older camper’s roof as
many weren’t built to support heavy weight. Any repairs to these types
of roofs may be safely accomplished by placing planks across the top of
the unit with the walls supporting the weight.
Just be sure the
walls themselves are not water damaged and can support your weight. Try
to stay as close to the side of the unit as you can while inspecting or
performing repairs to the roof. If the roof is badly damaged, you may
require scaffolding to span the distance across the roof in order to
access the repairs.
RV Roof Types
RV Roofing Types and Materials Used
There are several types of roofing materials used for RV roof coverings with each requiring different techniques for maintenance and repair. We will start with the older types and move on to the newer types. The “oldie-but-goodie” tow behind camping trailers of yesteryear are still around with some becoming highly sought after for restoration and investment.
Old Airstream, Avion, Serro Scotty, and other less well known but still classic models, are frequently spotted being towed by equally classic restored cars and trucks. The Airstream and Avion roofing material require special repairs not usually done by the amateur, so repairs for these units will not be included in this article.
The roof material on most older units consisted of sheet aluminum attached to 2x2’s reaching from one side of the unit to the other. These 2x2’s attach to the side walls and also form a base to attach the ceiling to. On some of these 2x2’s the roof sheeting may meet which requires annual sealant application to ensure watertight sealing.
The sides of the sheeting are usually screwed down the same way and require the same sealant applications. It is not unusual for holes to be punched into this thin roofing material by falling limbs or other debris. Fortunately these can be easily repaired.
Roof Inspection and Repair
If the hole is more than an inch in diameter it may be best to cover it with a small piece of aluminum sheeting. Cut the patch larger than the hole, use putty tape or other non-hardening putty around the edges, and use self taping screws to secure the patch to the roof.
Smaller holes can be patched with sticky backed aluminum such as Peel N Seal roof repair tape. The sheet metal screws which hold the sheeting down need to be sealed annually by coating them with a flexible rubber or plastic coating to prevent leaks caused by the flexing of the roof and body while the unit is being moved to or from the next campsite.
The newer camping units may use a rubber sheeting over the aluminum covering to insure waterproofing the roof. Once again, annual inspection and preventive maintenance is important to keep the roof in good shape.
There are products made especially for these types of roof materials and will protect and repair rubber roof coverings. Pay close attention to the area around roof mounted A/C units and any other vents used for gas refrigerators, air ventilation, or plumbing fixtures.
There are kits made just for replacing this rubber roof material available from RV dealers and suppliers. Annual application of a good sealant coating will save you possibly thousands of dollars in the long run.

RV Roof and Ceiling Inspection
Complete inspection of the roof includes checking the inside of the RV along the walls where the roof sheeting is attached to the edges. This interior inspection may include having to look inside cabinets and closets to see if water damage is apparent along the top sides of all walls.
Discoloration of the ceiling or walls indicates a present or past leak has occurred. If the discoloration is slight a simple sealing application may solve the problem. Rotting or mildewed wood indicated a serious need for repairs.
Check the top of the unit to ascertain the location of vents, A/C units or any other item which entails waterproofing. Check these same items on the inside to be sure they are still water tight. Many motor homes use vinyl stripping to cover the screws on the upper exterior of the unit.
These strips do not last forever and tend to crack and will fall out of the retaining groove eventually. Replacement strips can be purchase at many RV and camper trailer repair sites. These leaks are often hard to detect and it is a good idea to replace all of the stripping every five years or so.
Another hard to detect leak area is around the running lights. These lights use a rubber gasket to seal between the light fixture itself and the body of the unit. New gaskets or an annual sealing using silicone caulk will usually solve this problem. This type of leak may go undetected and cause deterioration to walls and floors.
Repairs on a camping units roof may run into thousands of dollars if the owner does not catch the leaks in time. Preventive maintenance is usually easy and relatively inexpensive to perform by most owners having basic skills. Just like our real homes, these recreational units need love and care to provide you with the best possible use. Happy camping.

Well, mine's already past the point of just seeling. My ceiling is rotted and sagging bad all around the vent in the roof. How do I replace the section of ceiling? I have a 15' field and stream from the early 70's that I love.
:)
Thanks
Can you tell me where the drain holes is located under the roof mounted A/C unit of a Coleman A/C unit? My A/C cools great but water is leaking down thru the return air cover. I assume there is a drip pan someplace under the unit but I can't see it from inside the cabin of my motorhome. Do I need to remove the top cover and inspect the unit from the top? Can it be blown out from the inside compartment?
Thank's Randy for the info. I will give it a try. This web site is lots of help for us newbies to Motorhome campers. One thing is for sure A person needs to be a jack of all trades or either have deep pockets to own a motorhome.

Im trying to find out what type of roof i have in my camper. I know it is not aluiumin. It feel like rubber , but someone told me i might have fiberglass. The roof feel like it is made out of canvus. Can anybody tell me. I want to use a roof coating for my camper, before the cold weather get here. I was looking at different type of liquid roof materials.
Thanks for responding. The make is a 1994 coachmen catalina. Its a 34 foot trailer camper
Thanks for all your help.
I built a wooden box onto a 4x8 flat trailer the whole box is painted with rustoleum but I need something to seal the roof which is also plywood do you guys have any ideas for me? it holds all out camping equipment.
just found a blister about 3"w x 2"h on the roof of my slideout on a 07 keystone,any advice with this problem...
Thanks for the info about cleaning the AC coils They were dirty as heck. After that I cleaned the roof with a commercial roof cleaner and some of the coating washed off and left several black places in the roof. Is the White Elastomeric Roof Coating okay to coat the roof? The roof isn't leaking any place and I want to just make sure the reflective coating is put back on.What is your advise about this? Thanks for your help.
I have leaks in the roof of my 2000 Thor Hurricane. I caulked the seam between the EPDM membrane and the retainer strip along both sides of the MH, leak stopped. Well the leaks are back so this time I am looking to seal the seam with a product called Eternabond. My thoughts are to apply the tape at the bottom os the retainer strip and wrap it up and over on to the EPDM sealing everything up. Any problem with this application?
i just bought a 10 324 fwbh keystone sprinter and seems to have a small leak on the roof of one of my slide outs, i live in the fw and i'm also kind of far from the dealer, i've been doing research on how to fix, theres not visible damage, the only thing that i guess is the sealant might be bad, and i've been considering applying liquid roof on it, any suggestions! it's cheaper buying the fix than taking it to the dealer since i live 350 miles away one way.
Recently I purchased a 2002 Lance pickup camper. The roof is aluminum in good condition as new. The problem is the oxidation from the aluminum has created severe black striping down the sides/back of camper that will not wash off using available chemicals purchased from RV dealer. Do you have any suggestions? Also, what is the best treatment to roof to prevent this from happening again once I get sides/back cleaned up?
Thanks for the article. I do have one comment for input. Many consumers choose not to cover their RVs during the winter (or any time of the year for that matter). There is a cost effective alternative. A fabric covered hoop building can protect RVs year round. These hoop buildings can be anchored to any surface including gravel, concrete, asphalt, and sand. This can help prolong the roof of an RV.
Hi Randy. I have 2 leaking questions: the window and the furnash. I bought a relatively new travel trailer a few months ago (it's is a bit worn) to live in temporarily and plan to sell this spring or late summer. Just noticed a leak near the front window beneath the shutter. The rubber seal piece has unpopped at one corner of the window so I caulked the gap without thinking to press the seal piece back in place. It's leaking worse now. How can I know if the leak is from the window or the roof? The trailer is not quite level, a bit low in front. The previous owner did repair work on the roof last summer and this is the only water I have seen inside the trailer. The wallpaper is bubbling but assume this is condensation? The furnas--when it rains hard or steady, a water puddle developes inside the compartment outside and the furnas does not ignite--tries several times and then shuts off. It works again once the weather improves and dries out in there. Should I be concerned? What can I do to prevent water from getting in there? I am missing one screw on the cover and there is black rubber seal around the compartment door. Should I replace the rubber or does this water indicate a more serious problem? Also the floors feels soft, more so when it rains and the furnas is out. Could there be structural damage? Would it be worth the cost to have the trailer re-sealed entirely if I plan to sell soon? If repair work can be done by me (I can't do the roof), like caulking, could that be done in wet, inclement weather? Looks like things will be wet until spring. Any advise would be great and thanks.
Thanks Randy. I was afraid it might be the roof. I don't know what type of material it is, maybe in the owner's manual. There is no ladder on back to climb up and take a look so I suspect it's not a walking on kind of roof, don't know. Plus, since I don't know what I'm doing and want to sell this soon, I would probably de-value it with any attempt to fix it myself. Appreciate the input.
I decided to have an rv tech come out and do an inspection and hopefully just a patch job.
I'm wondering though, my furnash shut off during a big rain storm last week. There was a puddle of water inside the compartment (outside of trailer) The rain stopped and things are dried out a couple days and the furnas is working again. This has happened a few times and I go ahead and use it if it starts, but is this safe? (I discovered a screw missing on the cover plate, maybe water is getting in there because it's not closed tight--there is an old screw broken off inside. I'll ask the tech about repairs so I can close it but wanted to get your advise about safety using furnash with water prob.
Thanks!
Thanks for all you help, Randy, much appreciated!
We need to replace our rubber roof on our Jayco 36' fifth wheel. Where can we get our supplys for something like that? Is it a complicated ordeal?
Randy, I have a basic Sun Valley 2001 26' travel trailer, no slide outs with a rubber roof. I sealed it up great at the beginning of the 2010 season but it still developed its 1st floor soft spots. I see nothing in the way of ceiling or wall water spots. The bedroom (front of camper) floor got real soft. I started ripping it up & found a lot of the particle board ( Why do they use this cheap crap ? ) deteriorated. It looks like I have to pull up the bed & bed side cabinets attached to the floor & replace the whole front section floor. Fun is ! My questions are: Where the heck could the leak be if I sealed the roof,door & windows very well? I also sealed the roof vents & skylights. How could my floor (which is soaking wet)be rotting out. Could this be from a couple years ago if I didn't do such a good job sealing? I didn't take the AC cover off ever. Do I need to seal there?( Quite a way from front floor) ( I did notice a bit of a drip during a rainstorm while the AC was on last year but I just read your string on how the AC drain clogs up & needs to be cleaned out so I doubt this led to my floor problem. My TV antennae is loose but I wouldn't think this is the problem? ANy tips so I can take care of the source prior to all of the floor work I need to do?
Thanks, Jeff
Me again. I was just reading these question/replies and have a question about floors. I have a Dutchman trailer and read your aticle on replacing floors on the Dutchman. Although I haven't noticed leaks inside the trailer or discoloration, the floor by the mid-to-rear section feels soft to me, squeeks in the same place every time I walk there. Also the floor feels soft, flimsy in the entire trailer but more-so in this section noted. An rv tech said the floor was fine and should harden when the wet weather passes.
The front window is leaking beneath the bottom shelve--I decide to caulk there instead of towing the trailer in for re-sealing. It appears to still be leaking a bit there, hard to tell since we haven't had a downpour since.
Any thoughts about the floor or window? The rv guy climbed up on a ladder said it actually looks pretty good but I'm wondering if you have to climb onto the roof and look close at all seals?
Oh, by the way, is silocone caulking best for exterior window?
A follow-up about the Dutchman front window. I asked a few weeks ago and you suspected it was probably a roof leak. The rv guy later looked and said the roof looked pretty good and touched up a front roof corner but still leaks. I caulked around the front window with silicon a day or two ago but appears to still be leaking a little, hard to tell. Two people have looked and suspect it's the window but how can you tell?
The siding slopes down over the front of the trailer in front and it would appear that water would drain down the front (the front slope out a bit). The shop said I'd have to bring it in to take a good look but they can only refer me to a glass shop if the window need to be taken out and resealed.
I can't afford the expense in this process of detecting where the leak is coming from, between the cost of a mobile rv guy to come out and look, towing the rig, hourly rate of inspection at the shop, towing it to a glass place and cost of taking the window out, ect, on a good hunch--as they say, there is no guarantee this is where the leak is either. Is there a better of detecting leak point-source?
Why can't they make rv's with thick, flexible rubber. We can send men to the moon but are still have leaky rv's. I'd propose designing an rv structure with a 5-inch rubber mold without seams to cover the basic structure to avoid these leaks. It just doesn't make sense to me that rv's are built the way they are. Can't wait to sell this thing.
Thanks, Randy. They say Dutchmens are good starter trailers for the new-be and when I read your article about floor replacement on the Dutchmen, I can see why the floors feel flimsy with limited support, and I am concerned about it deteriorating. It's a 2005 and I hope there is still some life to it.
Again, I really appreciate your advise about the roof. I keep coming back to the notion of resealing the roof to ensure all possible leaks are sealed, it's tough to choose between an expensive window job or an expensive roof resealing job--I sense this could run $1,500 - $2,000 easy. Maybe a do-it-yourself job this summer.
Thanks again. And hopefully there will be this Dutchman for sale for the next new-be rv'er :)
Hi Randy, it's me again. I guess it's my trailer morning.
I'm wondering, since there might be a short 24 hour break in the weather tomorrow with only 50% chance of precip, and even nice today asside from a few light sprinkles, maybe I could grab a ladder and get up near the roof and do some caulking along the rib where the siding begins down the front slope of the Dutchman trailer and re-do the window seal area.
Will rubbing alochol work to clean the areas before applying caulking and does it take long to dry? I'm guessing only a few seconds for alochol to evaporate. Do I scrape off and dig out the old caulking on the corners or just wipe clean and put new caulking on?
I have silicone and also this other stuff, all in one adhesive/sealand geogreen, 3 hour drying stuff. Should I stick with siliocone?
Thanks again. Think I will venture into the caulking once these clouds dispurse and "get er done." I have learned that a person really does need to be willing to try to do their own repair work if possible.
And yes, the Airstreams look great. I saw a small one recently, looked new and very nice!
i have a 1992 terry resort camper and i am having a hard time getting roof leak stopped, do you know what type roof was originally on it , it has been worked on several times
thanks
do you think peel and stick roofing works well? i am thinking about trying it
thanks
i just uncovered my camper and noticed some low spots on the roof, can i fill them in with something, maybe bondo? any suggestions? thanks for your help
Hi Randy,
Do you happen to know of a good product or procedure to clean off the black dribble stains on the side of my Dutchman and what those marks are from? It's starting to make my trailer look old and weathered. I have rubbed them out when drive and it comes off like black dust/smudge but it's hard work, doesn't all come off (stains!) and comes back the next time it rains.
Would that peel and stick (tape?) stuff work for my Dutchman roof and window, too? (regarding Kevin's question above.)
Thanks and good morning!
Mike
Thanks, Randy! With the nice weather headed our way, I can't wait to try this best black streak remover (very unsightly) and do more repair work.
Hi Randy. Can I bug you again? I know I've been asking lots of questions but I'm learning as I go along. I haven't actually done much work yet--missed a nice day today but hopefully it will be nice tomorrow, too.
I was just up on a ladder looking at the roof (2005 Dutchman trailer) and the roof appears to have a rubberized type fabric over the top, sealed along the edges. Someone caulked around the vents, ect. I can't see where any water would be getting in. However, the roof is not level--it dips down slightly as at quarter sections. Is this normal or damage?
Not sure how I would proceed in maintaining this roof--does this fabric peel off, does it need to be replaces every so many years? How would I scape off old caulking around the vents without tearing the fabric. What the heck is it?
Still don't see where water is coming in through the window... just don't see many cracks in the caulking...
Thanks, Randy. I'm glad to hear I have a rubber roof, it's a great idea to have a protective lining up there. It might have a fews blisters but otherwise looks pretty good. Thanks for the link to the repair kits above.
Yeah, I'm not sure about the window; please don't feel like you have to do any Dutchamn research, I was just curious. I tried re-caulking the window but it rained and washed off. Hopefully will get the chance to try again tomorrow.
Your Florida camping and fishing spot sounds great compared to this rain in the west, but summer will be here soon.
Thanks again!
Randy, would you happen to know about sticky awnings? I pulled my down for the first time (it's great! wish I would have done this sooner). Now I can't get it to retract. It's manual. I pull on the awning to release tension but the lever won't move at all. I have it fully extended and now I'm worried about wind.
I took the hook pole and just pulled down on the lever to open the awning, it didn't appear adjustable and the awning slide open so I assumed I did it right... I should have researched this before opening it!
I was just able to get it to roll back up by rolling the roller back and forth while trying the lever--the lever flipped to "roll up" after a few tries. Hopefully it just needs lubricating as you mention and not repair work.
Thanks much again for your advice, I really appreciate all the help you've provided and look forward to reading your awning article!
Whats the quickest way to remove the old gray sealer/covering ? I have a 69 Prowler and the covering is cracking. I started to remove and it's taking forever using a scraper and hammer (of which I punched a small hole in the aluminum) and a wire brush and grinder with a wire wheel. Is there a solvent out there to make this easier?
Thanks Randy ..... so I guess I just scrap and take off as much as I can and just cover it back over? Sounds easire than to totally remove.
is it possible to apply a rubber roof directly over the existing rubber roof?
actually i know better, but this one has splits on the edges giving me some wall leaks and just thought i'd check. the main field is actually in fairly good shape. i just keep being reminded by all those rv roofs i see on the side of interstate, and after looking at them i noticed that none of those have any indication of glue on them.
randy, are u in the service business? this is my 3rd unit to own and i'm beginning to feel like a journeyman on these things
Hi Randy!
I have a solvent question. I caulked around the window with silicone a few months ago and went over it with this All-in-One Adhesive/sealand Geogreen stuff used in construction trades, works well around sinks but it rained right and began washing off before it was able to dry (has a milky look). I tried to wipe off the remaining so I wouldn't end up with streaks down the front of the trailer.
Well guess what? I don't have so many streak marks from that milky caulking but do have huge smudge marks around the window and down the front of the trailer. Now that the sun is coming out from the dark winter, you can really see the discolor in it from dirt. I have ruined my pristine trailer! (in front anyway) Looks like crap.
Is there a solvent I can use to get this stuff off? And since the window is right above 2 propane tanks, would I need to worry about using combustable solvents?
We are starting to get some fantastic weather here at west -- what a difference it makes!
Thanks Randy. It looks like it actually discolored the paint, turned it gray from white. Maybe oxidized? I might try the rubbing compound. Thanks for the link to the cleaner. I'll let you know if I find a cleaner that works. I heard this caulking is great stuff but I'm guessing it's safe to say not to use it unless you are sure there is enough time for it to dry.
Hi Randy,
I bought a 2006 29'FEMA camper with a slide out that was never used before.
I recently notice slight water damage up on the side of the ceiling. I looked on top and noticed the seam on the edge of the roof was weathered and not doing its job.
The problem is the small leak has damaged the wood in the roof and I need to replace it.It feels hollow in a 1 square foot area
I'm pretty handy and just wanted to know what kind of job I have ahead of me.
I understand prepping is the most important part for a good seal.
Any advice would be great.
Thank you
I bought a 1960s-1970s norris camper it seems to be in decent shape for its age no major problems the roof has got den sealed and does not leak at this time however around ac unit it is starting to sag a bit is there any remedy to this and is there any other pertinent info on this camper? Thank you for your time
I just bought a 1997 Allegro Bay and it has a Duo-Therm AC. It's very difficult to follow the book on how to set the unti to run in the front and back. Is there any easy way to set the thermostat?
Hi Randy. Just dropping in to let you know that I never got around fixing the discolored paint from that caulking on the front window. I sold my trailer and evidently the window didn't look that bad, it sold pretty quick. I just wanted to say thanks for all your help during my RV adventure. It was a little more work/responsibility than I realized getting into it and I appreciated your help.
Randy, I have a 1985 Jayco pop-up. I need to replace the (aluminum I think) top and siding. Can you tell me how and where to find the material to accomplish this? I'd like to make the top with one piece of metal rather than having two pieces joined at the center. Any suggestions would be appreciated.
hi we have just bought an old millard and she has had quite a few leaks on her day my hubby is a plumber so fingers crossed all is well but we have decided after no leaks to redo the inside walls. it is a bit daunting any suggestions?
christie
thanks Randy that is a great idea!!
my add aroom is only one year old and it has a leak along the roof where the add a room is attatched to the rv i need advice how to repair it thankyou
My husband I just got a Dutchman Coach travel trailer. The person we bot it from had pretty much gutted the trailer except for the bathroom in an attempt to make a work trailer out of it. Since we wanted one to take to deer camp we thought nothing to expensive! Anyway, we are starting from scratch basically and I was wondering where can I go to get some good layouts for a 15 foot trailer? We are in the process of re-roofing since we have found some leaks that are going to require an new ceiling. The floor is in great shape and water pump works, air conditioning and heater both work so i think we are ahead of the game. We are both pretty handy when it comes to building and sewing so I just need some layouts. Can you steer me in the right direction? Thanks
Beth
And another question....do the existing floor to ceiling dividers that enclose the bathroom...are they there to keep the structure of the camper trailer 'true'? My husabnd seems to think so but iI think if it is aluminum and 2x2's the structure should come from that. Can you enlighten me? I would like to reconfigure the wall but he is afraid to....
Thanks
Beth
I have a 1996 Dutchmen popup camper that I bought used 2 years ago. The roof had a few minor holes in it, so I used a two part epoxy to fix those and then used Kool Seal to seal the entire roof-[I still haven't fiqured out tghe type of material the roof actually is]
I recently noticed a few more tears on the roofs edge-is using an epoxy a good idea on repairing this??
Also, the ceiling inside has an area that is rotten but I am not sure exactly on how to replace that.
Any advice would be greatly appreciated!
We have a 2006 Montana that we do not have storage for. I am seeing conflicting reports about recoating the rubber roof, some sites say just keep clean with mild product, which we do 3-4 time per year. When should we try to recoat or have dealer do?
Hi We bought a nash travel trailer not ago only to find out the roof leaks and the place went otut of business wheere we bought it so stuck now trying to fix it. it has a rubber roof I know andhave the rubber coating to redo the coating but we found out where it leaking and it has damaged the wood under neath which feels like luuan My question is can you cut through this rubber stuff and do small repairs the parts that are rotted are only about a foot square or so. I just don't want to cut it and be going some where and the roof go flying by.
We are restoring a 1969 Forester, about 13' The inside is gutted & we need to put some support in the roof as it is sagging. We are worried just adding additional 1 by 2s won't do it. Any suggestions?
