I have had many people ask me the question Can I Use Flex Seal on My RV Roof? In fact, I’ve asked myself that question once or twice. So, I decided to find the real answer once and for all. The short answer is – yes, you can use flex seal on your RV Roof! However, you do need to go into this with your eyes open.
Your new RV is your ticket to many grand open-road adventures. Therefore, it is essential to take good care of your RV. Proper maintenance will ensure you get many years of trouble-free travel from your investment. However, even the best RVs are susceptible to problems caused by normal wear and tear or even accidental damage.
One particularly damaging and costly repair issue for RV owners is a leaking roof. A leaky roof will quickly lead to other water damage problems and significantly decrease the resale value of your RV should you ever decide to sell it or trade it in. Therefore, the faster you can effectively stop a leak in your RV roof, the better off you are, period.

What Is Flex Seal?
Flex Seal is a brand of adhesive products, which most often come in a liquid form that then dries hard, aka “liquid rubber.” In addition to the classic spray, it’s available as a paste, tape, and a liquid. They also make other products, such as caulk which requires no caulk gun.
Its most common use for RVers is for releasing your roof to prevent leaks, usually using the liquid form. It can be used to fully reseal the roof, as well as patch smaller leaks.
Besides this most common use, Flex Seal products can be used in other ways, such as patching minor exterior damage or caulking in your bathroom.
How Much Is Flex Seal?
As mentioned before there are quite a few flex seal products, which can be found around the following prices:
- Flex Seal Spray, 17oz: $17
- Flex Paste, 9oz: $15
- Flex Seal Liquid, 16oz: $18
- Flex Seal Tape, two 3×4 in. squares: $13
So, in general, most Flex Seal products cost between $10 and $20. But, keep in mind you may need more than one container to fully reseal your roof, especially with a larger RV.
Types of RV Roof Repairs
It is important to remember that there are different kinds of repairs you may need to consider depending on the situation in which you find yourself. Are you home from a recent trip and have discovered a possible problem with a roof seam.
Or, are you miles from anywhere with a severe leak during a monsoon season. The situation you find yourself in may also determine what RV roof repair or sealer products are best, or even appropriate.
First, there is the permanent repair. Often this repair will be performed by an RV repair service or a dealer. It will take a reasonably long time to complete and will be quite expensive. However, if you are a do-it-yourself kind of person, there are products available to completely and permanently repair your RV’s leaking roof.
Second, you have a roadside repair emergency. For example, you are staying in a remote campground in the wilds of Nevada, and a tree limb falls on your RV roof, creating a leak. A leak like this is something you need to repair right away. And, often this kind of repair will be temporary.
Emergency RV Roof Repairs
A leaking RV roof is something that you need to fix immediately. The longer a leak continues, the more water damage will occur, and the higher the cost of any future repairs will be. When you discover a leak in your RV roof, you will need a way to quickly and effectively stop the leak. And you will probably need to do this with something you can carry with you in one of your RV’s storage compartments.
In a situation like this, one way to stop the leak in your RV’s roof is to apply a durable and waterproof sealant over the leaky area. There are many new rubber coating products on the market today.
Flex Seal is an excellent option to consider. However, as with any product, Flex Seal has its limitations. And, there are some advantages and disadvantages to using this product.
Advantages of Flex Seal
Flex Seal provides a low-cost option for an otherwise costly repair. Repairing a roof is going to cost much more than using Flex Seal. It dries fast and seals leaks within minutes of being applied. Flex Seal is readily available at a range of retailers and is perfect for quick fixes while on the road until a more permanent repair can be arranged.
Disadvantages of Flex Seal
Flex Seal is a temporary fix and not a permanent solution to a leak. Flex Seal should not be used to repair a whole roof. When there’s a lot of roof area to cover, you will want to consider other options.
Four Types of Flex Seal and How to Use Them On an RV Roof
Flex Seal comes in three forms: Flex Seal Liquid, Flex Seal Spray, and Flex Seal Shot. The Liquid and Spray both come in black, white, and clear. Flex Shot comes in white and clear. The great thing is that you can use Flex Seal with many all RV roof materials.
Flex Seal Liquid
Flex Seal Liquid is liquid rubber in a can and, it will stop leaks fast. It also will not melt, peel, or crack because of harsh weather conditions. Being a thick liquid, Flex Seal is incredibly versatile and can be rolled, dipped, brushed, or poured on surfaces. When it cures, you will have a waterproof layer of sturdy, flexible rubber.
Flex Seal Spray
Flex Seal Spray is the most commonly used spray-on liquid rubber sealer available. The convenient aerosol spray allows for the easy application of Flex Seal with no brushes or rollers required. However, be careful with the overspray. It can be a bit messy.
Flex Shot
Flex Shot is a perfect solution for those tight, hard-to-reach places. It is ideal for caulking around your windows or air conditioner, etc. It’s straightforward to use and will stop flowing the minute you release downward pressure on the bottle.
Flex Seal Tape
Flex Seal Tape can be applied to the leaking area of a roof before using one of the other flex seal products above. For example, the tape is perfect for a tear in your roof that could be caused by hitting a tree branch.
What Kind of RV Roofs Can Be Repaired with Flex Seal?
They are EPDM and TPO. Both TPO and EPDM are classified as rubber roofs, but they are a bit different in form and appearance.
TPO
TPO RV roofing is the most popular option for RV roofs in use today. It is a popular choice because it is inexpensive to buy and it’s white. The TPO membrane has a shiny, laminate appearance with the outer layer having a plastic look and feel to it. It can either be fitted with screws or otherwise mechanically attached. It can also be glued down.
EPDM Rubber Roofs
EPDM is a second popular option for RV roofing. It differs from TPO in several ways. EPDM is a synthetic rubber material that can be vulcanized. This means it can be dried and cured to form sheets. Alternatively, you can also use EPDM in its un-vulcanized form. In this form, it’ll never completely solidify.
It’s relatively common to use both EDPM types together for an RV roof. Vulcanized EPDM would be used for the roof membrane, while non-vulcanized EPDM can be used for any flashing or detail work. EPDM rubber roofs are usually maintenance-free for about ten years, but they will oxidize over time.
Fiberglass Roofs
Fiberglass is becoming a common RV roof material as well. These RV roofs, like EPDM roofs, will oxidize over time. Newer RVs with fiberglass roofs have a clear coat finish on them which does slow down the oxidation of your RV’s roof.
Metal RV Roofs
Metal was the preferred RV roofing material until TPO and EPDM showed up on the scene. Flex Seal will adhere to almost any surface including wood, metal, aluminum, plastic, fiberglass, rubber, vinyl, or just about any dry (or even wet) surface. You just need to be sure to clean your RV roof before applying Flex Seal. It does work best on dry surfaces, but if you are dealing with a leak during rainy weather, you can still stop the leak.
How to Use Flex Seal
A leak in any of these RV roof materials can be repaired using Flex Seal. Again, the important thing while on the road is to stop the leak and prevent further water damage. Flex Seal is an excellent product for that purpose.
Once you have completed your trip and you are in a position to schedule and complete a more permanent repair, you should go ahead and do so. Flex Seal is an excellent temporary fix for your water leak, but it is not a permanent repair.
Does Flex Seal Work as Well as Dicor Lap Sealant?
Dicor Lap Sealant is another often recommended option to repair RV roof leaks. Dicor Lap Sealant is a self-leveling compound that is applied in a bead that will then spread and seal the leak. By most accounts, Dicor Lap Sealant works well and is an excellent product.
The drawbacks are that Dicor Lap Sealant requires careful prep work and the proper temperature conditions to level and seal properly. This prep work and ideal temperature conditions may not always be possible or available during an emergency repair while touring the Alaskan wilderness or a desert in the Southwest.
You can find various opinions on both Flex Seal and Dicor Lap Sealant as to these products’ performance and reliability. When you have the time and right tools to properly prepare the leaking area for repair and the right temperature to allow Dicor Lap Sealant to level and seal the leak, it is indeed the better product.
However, when you are pulled off on the shoulder of the Trans-Canada Highway with a leaky RV roof, and the storm clouds are brewing, having a few cans of Flex Seal Spray in one of your storage compartments might be just the thing you need.
Can You Pressure Wash Flex Seal?
Flex Seal doesn’t have any specific information about pressure washing their products, so it’s hard to say definitively if it can be pressure washed. However, they indicate that their products can withstand a “wide range of hydrostatic pressure,” so it may be fine.
If you’re concerned, you may want to consider applying a small patch of Flex Seal and pressure washing it to be sure. Depending on the conditions, the exact product, and your RV, it may or may not withstand pressure washing.
What Have We Decided About Flex Seal RV Roof Repairs?
Many RVers have used Flex Seal for repairing leaks in their RVs. From reading RV forums, it is clear that some were very happy with the results while others had nothing good to say.
Relying on Flex Seal as a permanent solution to a leaky RV roof may not be a good idea. It could be argued that Flex Seal is not designed for RV roof repairs. However, many of the negative reviews seem to stem from those expecting Flex Seal to be a permanent repair.
The ready availability of Flex Seal at major retailers, as-seen-onTV stores, and online, makes it very easy to keep a few cans of Flex Seal Liquid, Spray, or Shot on hand for emergencies. It might not hurt to have a roll of the tape as well.
Flex Seal is also relatively inexpensive. You can apply it on almost any surface, in cold weather, hot weather, dry surfaces, and wet surfaces. It does stop leaks and will certainly get you to a point where you have the time to shop for a more permanent roof repair for your RV.
Personally, I keep a roll of Eterna Bond Tape, Dicor Self Leveling Lap Sealant Caulk, and another tube of Dicor Non Sag Lap Sealant Caulk on board my RV for any emergency repairs I have to make. I’ve used flex seal and although I think it worked, it was really hard to work with. Have you used Flex Seal to make a repair on your RV Roof? Please share your comments about it below. You never know but your comment could help a fellow RVer!

I have a 2002 forest river with i think is a butyl roof. I have no leaks but it was getting chalky. I had several buckets of Henry’s fibered aluminum roofing so I coated the entire roof. The next day I noticed wrinkling that wasn’t there before I coated it. Did I mess up and cause separation of the roof?
Hello Mike, I have a model home
trailer with shingles. Wondering would I be able to use one of the clear flex seal on the shingles if I
had a leak?
Thank You for Reading.
Hi Kelly,
I think Flex Seal could be a great temporary fix but not a permanent solution.
All the best!
Mike
My fiberglass roof has multiple leaks and the roof has delaminated from foam. (I have a Gulfstream BT Cruiser. I just bought and found damage after I got it home)
The bottom of the luan is soaking wet. Would you suggest I tear out the foam and let it dry out and seal the top with Dicor and kool seal or replace all the fiberglass with TPO?
Hi CJ,
You may have to replace the wet luan before anything else…I think replacing the fiberglass with TPO might be a good idea…you could also take it to an RV mechanic and get some advice too! You might still do the work yourself but at least you will have a good idea of what todo.
Thanks!
Mike
I had used the Flex Seal spray on a few spots on my rig, but discovered a rather large leak(s) where the front panel meets the roof. It had been raining very hard, but eased up to a sprinkle and it was just above freezing, so I went with the Flex Seal liquid. Things were much better, until. . .
A few weeks later, when the almost 100 mph winds came through our area – they peeled the Flex Seal liquid right off the roof in chunks over a foot long and a few inches wide. I also lost a few patches where I had used the spray.
Looking at the pieces that tore off, it looks like cleaning the roof was insufficient, as a very thin dusty/papery layer of the degraded roof (we’ve been full-timing in this rig since 2004) came off with the Flex Seal.
I have seen denatured alcohol repeatedly suggested at a safe and effective cleaning agent. Is this the best choice, or are there other options. Do I need to lightly sand (best grit?), too?
There’s a very important point: for all I can see it seems that FlexSeal is silicone based, which creates a number of problems in the long run. If you look at two competing products from Gorilla and RustOleum you will see that those are paintable, while FlexSeal is not, and that is a pretty important sign.
Because of that I used the Gorilla rubber instead. So far so good…
I do not have a leak yet in my trailer, however I believe an ounce of prevention is worth a pound of cure. In this case I have used Flex Seal white liquid rubber in the gallon size and I have coated the top of my trailer roof as an extra layer of sealant and protection for my ‘Home away from home.’
I am with you wholeheartedly when I say Flex Seal is not a permanent fix to a roof leak or repair. But rolling a layer on the entire surface, paying attention to cracks,openings and already sealed air vents, A/C and & other openings and corners in the roof makes perfect sense to me. It adds another coat of water proofing and prevents UV damaged caused by the sun. It penetrates and fills small cracks waiting to expand and get bigger with expansion and contraction of temperature extremes caused by the weather. If nothing else, it is an $89.99 can of peace of mind.
I have a 1997 Jayco Designer Series smooth side 31′ fifth wheel. I had a persistent leak from the roof when raining from a certain direction. Eventually figured out it was coming from the old roll up winegard antenna. I remover the antenna completely (no use for it) cleaned up the plywood and cut back the loose part of the epdm roofing to where it was still attached to the plywood. I put down two layers of white flex seal tape, and then I leveled the area off with white flex seal paste (hint, dip your spreader in water when you are doing the final smoothing of the paste). It sets up fast, the repair was 100% water tight, and when I go back this fall, plan to coat the area with two coats of white koolseal roof coating (which also works great by the way). I have also used the flex tape along the seams of the slide out roof to replace old seam tape. Works great there as well. Once it takes a set, you can not pull that flex seal tape off. Highly recommended for both temporary and am thinking it looks promising for a permanent repair as well.
Great info!
Thanks for sharing!

Haven’t had to use Flex Seal for a roof leak — However, it has worked well as a temp fix for a freshwater tank —- Driving down the road, hit something in the road, I couldn’t avoid due to traffic in lanes on each side…. It knocked off the drain point, not just in the threads of the pipe connection, but into the area of the tank around it, so no permanenet repair without new tank
Flex Seal paste, and liquid were utilized to seal the hole – about 3-4 square in oval hole…..
Saved a long trip — haven’t gotten the replacement tank yet, and must Pump the excess and antifreeze out during cold weather, since I lost the drain —
Good stuff — takes a day to dry sufficiently to hold the water in the tank…….
I have a small leak around roof vent. They are calling for rain tomorrow. I have a can of clear flex seal spray. Will that work in 50 deg temperature? We are traveling for another week before we can get it under cover .
That should work!
All the best!
Mike
Used white liquid Flex Seal on a Coleman 2001 Sea Pine. The roof had many, many small cracks plus a couple of dollar bill size bubbles. I ground out the bubbles and used Flex Seal caulk to level the top. Then use the liquid Flex Seal on the whole roof. It filled the small cracks very well and over the repaired bubbles (Flex Seal caulk) so that I have to point out the location to even notice. Been two years now and it continues to look like a brand new roof. I do use a form fitted storage cover each winter. I am extremely pleased with the “permanent” nature of the Flex Seal and will use it again should it be needed.
Hi Charlie,
Thanks for sharing your experience with Flex Seal.
Mike
I used the liquid Flex-Sael on my seams on my rubber RV roof. Applied with a paint brush. I can’t imagine anything being any easier to use. It seals great. The only thing I wish is that there was a choice of color other than black or white, at least at my store. Wound up buying a can of outside spray paint. Which took about 15 mins to paint the roof seams.
I apparently hit a tree branch and took out a piece of my skylight on my new fifth wheel. I didn’t notice it until I returned home from a trip. I saw it from my 2nd floor window. Luckily it was dry and hadn’t rained before I saw it. I did some research and used the self leveling sealant when replacing the skylight. I used Dicor self leveling lap sealant. The unit is under warranty and the repair is indistinguishable from the factory original. Having completed the aforementioned repair I have a few concerns about Flexseal. I had to scrape and remove the sealant to get to the screws holding the skylight. The factory self leveling stuff was semi-soft and scraped off fairly easily. The screws, although not completely clean of sealant, were easy for my screw driver to grip and remove and then replace. I did not remove 100% of the old sealant it was smooth and pliable. I put a thick bead on the skylight, screwed it down and applied the self leveling sealant to the screws and flange of the skylight. Would Flexseal have been as easy to remove? I believe the repair would have been much more difficult had the skylight been originally installed with Flexseal.
Hi! My husband and I are full time RVer’s. I really appreciate your knowledge and will save this in my maintenance folder. We live on the Intercoastal Waterway in NC. We live in a RV resort. Been through some rough hurricanes in the last three years. Obviously we were mandator evacuated with the rest of the area. We are doing our roof this year, your information is very valuable. My husband is really handy with electrical but coating a roof, well we wanted to do it cheap and as solid as possible, as next year we plan on buying new one. You have great information. Thank you!
we have a hybrid tent trailer, (the beds open on either ends like a tent trailer but the middle is enclosed with metal/fiberglass not sure) and have started getting tiny pinhole leaks in our tent trailer ends. Husband tried a product a couple of years back that seemed to work but wondering if Flex Seal painted or sprayed all over the canvas could help keep trailer dry and fill the pin holes. Has anyone ever used Flex seal on the canvas, or can you recommend the best product to make the canvases waterproof and worry free?
Hello, and thank you for your article.
We have a 95 Jayco that we bought from a friend for a super low price. It had been sitting about 8 years plus in their back yard.
Knowing nothing when we started this process, we pulled it home and started to remodel inside to make it ours. We soon discovered lots of new leaks and realized the roof had become quite “crispy”. We used flex seal over the whole roof after replacing materials up there and inside. Tarped it worked slowly on the remodel. Two years later we are finally camping and loving it. Then it rained heavy for a few days. At least 6 leaks.
My hubby is thinking flex seal again, but after reading your article I am wondering what our next step should be.
What did you end up using and how did it work?
waiting for new skylight to arrive and install. Have crack on 3 out of 4 corners and some wet weather expected before the new one arrives. Was going to try using Flex Seal clear Spray on corners and a temporary fix. Should I scruff the corners with fine sand paper before applying? or if you have another suggestion, I am open ?
Hi Dee,
It will hold a little bit better if you use the sandpaper on the skylight.
Thanks for reading the article and for your question!
Mike
This is an excellent article as well as the comments and answered several questions I have had in regard to RV rubber roof repairs. Thank you very much.
Thanks Larry,
Glad you found the article and the comments helpful!

Will flex seal adhere to silicone? Prior owner smeared silicone caulk to make a roof repair
Hi Vince,
I would recommend removing the silicone. I don’t think Flex Seal will adhere to it.
Mike
I’m not an RV owner…..YET. I really want to be, so I’m doing all of my due diligence and researching RV repair and maintenance so I’ll have some idea of what I’m getting into. Thanks so much for this article, it (and the previous comments) has been most helpful!
Hi Holly,
Glad you liked the article and some of the comments by our readers!
Let us know if you ever have any questions!

Can i use a thin layer of self levering sealant on Entire rv roof ?and will i be able to walk on the roof after it cures or will it stay sticky
I have a motorhome with a fiberglass roof not leaking but chalking badly, 20 years old. Would flex seal work on entire roof?
wonder if you could put new gel coat over it they do it on fiberglass boats
I just saw your info. Great information and clearly stated.
Will be reading your posts.
Thank you from the Great state of Texas
Hi Sharon,
Thanks very much!
Mike
I have a 2019 Landmark by Heartland. From the ground level looking up there appears to be either wrinkles or air bubbles in a few areas next to the trim line on both sides where the roof meets the painted fiberglass. I am a disables veteran and can not get on the roof to see it any closer.
Would flex seal white tape prevent any further threat of a roof leak? Rubber roof.
Myers
Hi Myers,
I only recommend Flex Seal for temporary repairs although plenty of folks say it lasts years. I have not had that experience with Flex Seal myself. If you need a cheap fix perhaps Eterna Bond tape would be a better choice.
Mike
I used Henry Tropi Cool on my Roof before renewing seals. I had to clean all sealants off with Denatured Alcohol because nothing stayed on the Silicon Roof. I resealed all Roof with Dicor self leveling . .Its still soft to the touch after 3 days. Can I reapply another coat of Tropi Cool (100% Silicone) ? If I paint over the Dicor sealant is that good enough for not letting water into the sealed areas? No tape will stick to Silicone I found out the hard way.
Hi Angela,
I don’t recommend silicone on your roof at all so I’m not sure where you would go from here…
I used Flex Seal on the first foot of my awning. It was starting to degrade and you could see pinholes starting to develop. The Flex Seal provides protection from the sun, fills the pinholes, and strengthens the awning. Been 2 years and looks good
Hi Dave,
I’ve never even thought about using Flex Seal on an awning!
What a great idea!
Thanks for sharing!
Mike
I used spray flex sealmon my awning. Worked great. I used flexseal on a corner of my rv due to water damage. Help up 5 years
Rightly said, a leaking RV roof is something that must be fixed immediately. The longer you wait for the more water damage will occur. Identifying roof leaks can be difficult and may over time reoccur. So, why not choose Liquid RV Roof and stop worrying. It is a cost effective, easy to apply and works extremely well on water leaks and punctures.
Hi Nicole,
I am finally letting your comment go through – Liquid RV Roof is certainly a good solution for roof leaks too!
Thanks
Mike
Good morning everyone I’ve used the flex seal around some edges and skylights so far so good what I want to know is there anything to use besides dicor prep to prime (get it clean ) before using dicor.?
I do not recommend any petroleum products at all if you have a rubber roof because they can damage your roof.- but denatured alcohol should be safe and do the trick.
Thanks for reading the article!
Mike
I had to replace a broken plumbing vent on my 5th wheel. When removing the old vent and the old sealant the wood roofing shows. Do i need to put something down before i apply the Dicor self leveling sealant?
Hi Jennifer,
You can use the Dicor Self Leveling sealant right on the wood. And actually, nothing sticks better to wood than Dicor so you should be good to go!
Good luck and thanks for reading the article!
Mike
Use flex seal. Don’t mess around with the crap. I have used them all. If you don’t want to have to continually mess with your camper use eterabond tape over all seams then put a coat of flex seal over whole roof. Anyone that says it is temporarily either hasn’t used it or is trying to sell something. It is the most permanent fix I have ever used. I have 3 rvs all have flex seal. The first one I did 4 years ago I only check 1 time a year and it is holding great. Everything I have used before I had to do every year.
Awesome! You always go one step beyond when you write your articles.
There is so much great, useful information here. Thank you!
Ash
Thanks Ash,
I really appreciate the kind words and I’m very happy you found the info to be helpful!
Mike
We are hosts of a campground in the mountains of NC. We have put 2 coats of white flex seal on our 2002 Glendale titanium roof. The results have been great. My wife has put this on over 10 campers. It seals good, reflects heat and feels soft after 3 years. If I had to reapply every 3 years it’s a great option for extending the roof life. I honestly can’t think of any reason that it would be a bad thing to use.
Timothy
I like you have used & keep a roll of Eterna Bond Tape. I have a patch on the roof vent attachment border & front corner of a metal roof. It has lasted 5 years & shows no signs of any deterioration. Glad to hear that flex seal is a good option. You never know.
Hi Earnest,
Wow 5 years is great for a roof repair!
Eterna Bond works wonders.
Thanks for visiting the website and reading the article.
Mike
It’s time to roll a new coat on my rv rubber roof. I have no leaks is flex seal a good product to use on your whole roof?
Hi Mike,
Great question. Well as I mentioned in the article and the YouTube Video I think Flex Seal is a great product to use for a temporary repair. Since you are looking to make a more permanent roof seal I would recommend using a product specifically designed for your type of RV roof.
Thanks for asking!
Mike
yes ! We have a Lifestyle 5th wheel and put it on right when we bought it new 3 YEARS AGO. It worked wonderful and we live in AZ fulltime….HOT. Used 3 gal on a 36 ft roof, mark off 3 sections then roll each gallon on. Used a brush to do around the AC units etc. Husband checks it every year and it is excellent. Really great stuff….be sure to start in the far end and roll toward the ladder…lol.
Yup just coated my 31ft travel trailer roof was not leaking but needed a little TLC used 2 1/2 gallons on it looks great did my slide roof two years ago and the flex seal held up great. I expect the same results
Which product did u use
What was the stuff you used on the roof
1 yr old camper during a recent rain storm showed signs of a leak. We are camp hosts far away enough from home that we needed a fix before the next days rains came. We used painters tape to tape off the black side gutters then used the spray flex seal in the area around the seam we felt was leaking. So far so good no more leaks!
This is a great site. Good info. I bought a used camper. The roof material has worn down so that there is no longer any white surface left. It’s all black! What product can I use to resurface the whole roof??
You could try liquid rubber roof but you may have to just replace it.
Sorry…
Mike
I have used Flex Seal around a skylight vent. Peeled off the material that the manufacturer had put on and painted on the liquid version.
It is going on two years now and still looks and feels tougher than the original material.
Hi Scott,
I’m impressed that the FlexSeal has lasted two years and thanks for the feedback!
That’s good to know.
Mike
Hubs used it on our 1985 Komfort which had a leak and for three years now, no leaks at all. Would recommend it for all RV roofs.
Hi Kay,
Glad it worked for you and your hubby!
Thanks for reading the blog and for your comment!
