RV Roof Maintenance Over the Years

Most RV roofs will last around 30 years, but after about 10 years, it's a good idea to start looking closely for leaks, cracks, or other damage that may lead to replacement of the entire roof. For the best results and the longest-lasting roof, it's best to check the seals and edges of the rooftop at least once a year.


Over time, parts of your RV will begin to wear down, especially the roof which receives daily beatings from all weather conditions. In these spots you'll begin to see holes or cracks appear. To prevent leaking and further damage to your RV, you can use Alpha System's patch kit for Superflex membranes. The kit includes a small piece of roofing membrane and a tube of self-leveling sealant, which you can use to seal the edges of the membrane.

2019 Winnebago Minnie Travel Trailer
This product was exactly what I needed to repair 2 quarter sized holes and a few smaller holes that developed on our Winnebago roof over the winter. However the kit does not include an adhesive to attach the membrane to the roof, the adhesive I used (Alpha Systems 8019) was only available from etrailer by the gallon (even though I only needed a tiny fraction of that), and exceeds the price of the patch kit. Some reviewers appeared to use the lap sealant included in the kit as an adhesive and reported poor results. The lap sealant is intended to go over the patch edges after it has been adhered to the roof to create a water tight seal around the patch. Using the bonding adhesive to adhere the patch and then sealing the patch seams with the lap sealant was fairly quick and easy for a DIYer, looks good and I expect lasting results as the patch material is guaranteed for 15 years. I spent over twice what I expected and have close to a gallon of adhesive that I’ll have to toss (it keeps up to a year according to the label), but it beats the repair bill. The etrailer reps are helpful, knowledgeable and quick to respond.

Product was exactly as expected. Matched the material on the roof of my 2019 Grand Design Imagine. Packaging needs to be addressed - the box arrived almost completely broken in half because the heavy tube of sealant was at one end. I've seen other reviews that identified the same issue. Some filler material to center the filler tube lengthwise in the package would solve the issue.. but the product wasn't damaged in my case.

To use, buy some good spray contact glue and a small seam roller. Clean damaged area with alcohol or acetone, lay replacement piece over area with a couple inches of overlap after spraying bottom side with contact glue, roll the overlapped part with the seam roller, and apply a generous bead of the sealant over the seam. Good as new!
by:
The patch membrane material tends to wrinkle up around the edges while the sealant cures. For my first attempt at patching my roof hole I cut the patch piece in a nice oval, laid a nice even 1/4" bead around the bottom side of the patch and pressed it onto the roof until sealant squeezed out all of the edges. The next morning it was all wrinkled up around the edges and there were lots of openings in the sealant. Maybe I was doing something wrong, but I wouldn't know because it didn't come with instructions.

For my second attempt I did the same thing but left a 55lb bag of sand on top of it for three days while the sealant set up. Perimeter seal looks intact so far. Will see how long it holds

I have lost track of how many times I have ordered from etrailer
We just purchased our third camper last month so I will be ordering more products soon.
I also read the repair articles and found out what the fix was with my fifth wheel brake problem .the photos I have attached are of spring shackles that were about to fail-replaced with heavy duty parts from etrailer and a new air ride hitch.
Thanks etrailer for your great support and service

This was the 2nd time buying this product. The 1st time I didn't see the included instructions, and ended up using the included tube of self-leveling lap sealant to use as an adhesive. As you may have guessed, it went terribly and I had to rip it out and start over. I used spray contact adhesive and prepared the existing roof with acetone the second time. There are 2 sides to the rubber- one was smooth and 1 was textured- I put the smooth side up (not sure what side goes where) I finished the edges off using ETERNABOND tape (not shown)
Overall I feel confident that the repair will work. Next step is to acetone, Clean, prime and seal using Liquid Rubber
I don't know why there is a tube of lap sealant included, but it did go to use on other areas of the roof

Very disappointed. While easy to cut and fit, the edges started to curl up almost immediately. After sitting for 10 to 15 minutes, large bubbles started to appear despite extensive use of an appropriate roller. Result is I will have to take my RV to a professional shop and have the rubber roof on my slide-out replaced.

2018 Heartland RV Cyclone 5W Toy Hauler
Easy to use. Excellent results. I used this this product 4 years ago on my 5th wheel toy hauler and it went on easy and still looks great today. My friend had a leak in is motor home and I suggested this product we received it in a timely manner, installed it before the next rain and he is overly pleased with the installation and results.
by:
The patch membrane was exactly what I need for a repair. I was confused and could not understand why a small quart-sized of adhesive was not part of kit. This would have been more productive for the fix other than the self-leveling sealant enclosed, I applied Eternabond tape to seal the edges. No instructions (or video) for the DIY’s.
by:
The box was broken in half, and was missing lap sealant. Also part of roof material was torn.

I have dealt with e-trailer several times and have never been disappointed with their products or their service. Very high-quality products and their service is second to none. Great at keeping one informed as to the progress of your order and excellent follow-up to be sure you are satisfied with your purchase.
by:
i actually patched a metal roof on my fish camp with this kit. Worked out well for me. My only negative comment is that ETrailer should have protected the sealant tube. The gorillas at fedex tried to smash it. Some product escaped. The box looked like they stomped on it several times. Its why I don't use fedex.

Do you have a question about this RV Roof Repair?
  • Should I Replace or Reseal the Roof on My 2005 Keystone Sprinter Fifth Wheel?
    Hi Deb, first, I just want to say I'm really sorry to hear everything you've been through. I hope this Keystone gives you a safe, comfortable place to call home, and I'd be happy to help you make the most of it without spending money where you don't have to. From everything you described, I would not replace the entire roof membrane right now. A chalky TPO roof is very common as it ages, and by itself it doesn't mean the membrane has failed. Since you're not seeing any active leaks inside,...

  • Is Alpha Systems RV Roof Patch Kit Self-Adhesive
    The 3' x 2' Alpha Systems Patch Kit for SuperFlex RV Roof Membranes - White # AL37CV is not self-adhesive. It does come with self-leveling adhesive that you'd use, however.

  • How Can I Tell What Roof Membrane My 2000 Dutchman Aerolite Cub TT Has?
    I don't know what type of roof is on your 2000 Dutchman Aerolite Cub TT however I can help you determine what roof you have. TPO is going to be on the thicker side (1.1mm - 2mm) than the EDPM membrane, and also has rubbery feel to it. EDPM on the other hand is going to have a smooth finish to it compared to the TPO, and it is also going to be quite a bit thinner at around .40mm - .90mm. As far as repair kits go that does depend on what you're needing done. For instance, we have the Alpha...

  • Will The Alpha Systems Patch Kit Work On All TPO RV Roofs
    The Alpha Systems Patch Kit for SuperFlex RV Roof Membranes # AL37CV is designed for TPO membranes so branding would not matter and you'd be good to go regardless of which brand your roof is.

  • Recommended Solution to Patch A Hole Where An AC Was On an Older Thor Ambassador RV
    I recommend just using a patch kit like the Alpha Systems Patch Kit for SuperFlex RV Roof Membranes # AL57CV to cover the hole. Since you're planning on getting rid of your RV anyways this'll be the best, relatively inexpensive solution. This kit includes a 3' x 2' membrane patch which will be plenty big since the average roof vent is 14-1/4" x 14-1/4", along with some self-leveling sealant. This patch kit is grey, however we also have this available in white # AL37CV if that works better...

  • How To Identify What Type Of Roof Membrane Material Is Used On Your Motorhome
    One way to identify the roof material type without removing it from your roof is to go to your vent fan and remove the inside trim cover. Manufacturers will typically pull it down and staple it to the vent opening. You can remove a staple or two if needed to lift it up and examine both sides. if one side is a different color than the other then it's EPDM and if both sides are the same color it is TPO. Another way to check is to remove the trim strip on the outside of your RV where the...

  • Recommended Tow Bar Wiring For A 2024 Ford Bronco Black Diamond Edition
    Hey Paul, For a 2024 Ford Bronco Black Diamond the harness is going to vary depending on tail lights. I'm assuming you likely have LED's but we'll also need to see if you have variable voltage wiring. Variable voltage tail lights use the same wire for the brake signal and running lights instead of the standard turn/brake wire setup. To determine if you have variable voltage tail lights you'll need to pull the tail light out to get to the wiring and test wires with a probe tester # PTW2993...
