Seal Team Sikaflex 715 And 521
With the decals removed, and the filon de-oxidized, the next step was to caulk and seal our camper. Having been to all the factories, we knew we wanted to use Sikaflex 715 for our TPO rubber roof, and Sikaflex 521 for the exterior filon.
Sikaflex was first brought to our attention by Bob Mehrer of Snowriver in 2007. Bob had tested various sealants and had concluded that Sikaflex was the best. In 2010, Mony Penn of Eagle Cap had also tested Sikaflex and was using it exclusively on Eagle Cap campers for the same reason. Other industry veterans over the years had told us much the same Sikaflex was expensive, but worth it.
TIP: In our, Maintaining Camper Seals article, Mike Kernagis, Service Manager for Palomino RV, recommended Dicor self-leveling sealant for TPO rubber roofs, and Geocel MHRV for exterior filon. Dicor and Geocel are what most RV manufacturers use at their factories and are less expensive alternatives to Sikaflex.
Reasonsto Reseal Your Roof
A leaking roof can quickly become a traveltrailer owners worst nightmare. Even the smallest of holes can lead tosignificant damage and expensive repairs. Because of this, it is recommendedthat trailer owners regularly check up on the condition of their model, andhave it sealed at least once a year.
Leaks can occur from a number of things,whether you are aware of the cause or not. Below are listed some of the topcauses of roof leaks in a travel trailer.
- Roof Damage The leading cause of a roof leakis damage to the roof itself. Falling tree branches, high winds, or sustainedweight on the roof are all examples of how damage could occur and be followedby a roof leak.
- Faulty Sealants Many of the pieces on theroof of a trailer, such as the air conditioner or vents, are sealed using asealant system. Over time and with exposure to the elements, the sealants canwear down or dry up. It will then pull away from the seam, leaving cracks andspace for water to get inside.
- Aging As is with most things, as the age ofa trailer advances so will the issues that occur. Things will not work as wellas they used to or seal to the same ability as they did on a new model. Anaging roof on a travel trailer can diminish its effectiveness to keep out waterover time, regardless of care or maintenance.
How To Fix A Leaky Skylight Roof Vent Ac Unit Or Hatch
Since RVs rooftop systems such as the A/C unit or roof vent are essentially holes cut in the roof, the edges around them can develop leaks that you will need to fix to avoid water damage.
Luckily, its a pretty easy job:
Scrape away any residual silicone caulking.
Clean the surface of the roof around the leak with a plastic scrub pad or sandpaper, then swab with a solvent-soaked rag.
Seal the edges around the vent or system with sealant or sealant strips, covering all screws.
Position the vent flange so that it overlaps the roof surface by about two inches in either direction, and be sure to roll-in the sealant so that it bonds permanently.

How Often Shall I Reseal My Trailers Roof
If you have faced your travel trailer roof sealing issue recently, you might also be asking yourself how often this procedure should be done.
Well, if you want to keep your trailers roof properly sealed and avoid any leaks, you need to consider resealing it once a year annually.
Like this, you will make sure that the roof is in a good state and you will also avoid not only leaks but even extend the lifespan of the entire trailer!
In addition, except for regular resealing of the campers roof, it is also recommended that you check the roof for leaks and sealant deterioration.
This should be done twice a year at least. It will help you to skip any mishaps that may come with the roof issues.
And please remember that without a properly sealed roof, recreational vehicles are way more prone to leaks, further degradation, and thus expensive repairs.
A proper and in-time reseal will prevent all this from happening, and keep you on the road in your trailer longer.
Now, we guess, you might be wondering how the sealing/resealing procedure should be done correctly, and whether it is ok if you do it yourself. Well, lets figure this out!

Tape All Edges And Seams With Eternabond Tape
Once the sealant has been allowed to dry, you can add an additional step to protecting your RV roof from future leaks by adding a strip of Eternabond tape in a few places. Eternabond has long been used and recommended both for DIY RV roof repairs like this, to avoid more expensive dealer maintenance, and for patching holes to prevent a leak in the event of an emergency on the road.
We recommend that you use generous strips of Eternabond to cover any weak areas of the roof that show wear, significant cracks or holes in the surface of the roof material. We started taping around the front cap of our motorhome using the 4 wide Eternabond. This covered the seals and all of the new sealant we just applied.
Then we ran the Eternabond lengthwise down both the driver and passenger side of the RV roof. We folded the tape over the edge to cover the screws on the side of the roof seams and wrapped it over the corner edge to cover loose areas of the EPDM that were starting to show cracks sure to lead to a leak.
Take it slow, and use an old credit card or plastic putty knife to flatten the Eternabond as you move down the length of the RV.
Use the same principles as you lay the Eternabond over the rear end of the roof as well.
Last, be sure to cover any clear tears on the surface of the roofing material or anywhere that looks weak and could lead to a future leak.
How To Use Flex Seal To Repair Rv Roof

Cleaning The Existing Roof Seals
We started by unloading our camper so we could access, inspect, and seal every part of the camper, including the front wall and underside. We also didnt want to get any sealant on our truck.
Once demounted, Bill handed us gloves and a small container of acetone. The acetone, as Bill explained, would clean the existing seals so we could see the condition of the seals and determine which seals needed repair.
Acetone is a colorless solvent commonly used to remove nail polish, and as a paint thinner. The RV industry uses acetone extensively for cleaning and removing dirt and sealants before applying fresh sealants.
Gloves on, we climbed up the rear ladder of camper to inspect and clean the roof seals. Angela wasnt wild about the ladder, so she climbed up through the cabover roof escape hatch. She much preferred getting on and off the roof through the escape hatch.
The acetone made fairly quick work of cleaning the seals turning them from a dirty grey-white to a clean off-white. The acetone seal cleaning also quickly revealed seal breaks and potential leaks. Specifically, we were looking for cracks in the roof seals or any place where the sealant had come away from the roofing material.
Heres how Bill showed us to test roof sealant:
2. With your fingers, push on the sealant and check if theres an air pocket underneath, or if it moves. Good sealant will be tight to the camper with no air pockets and will not move.

What Happens When You Dont Repair It
Harm to RV roof will take a range of shapes. If you are a full-time RVer, if you are going out once every season, the RV roof may be affected regardless of where you go. Any damage to the RV roof, such as rot, leakage, and rust, can be caused by water damage. Water can reach your RV quickly and, in a short duration, cause several difficulties.
#This kind of damage to the RV roof will incur thousands of dollars in maintenance. Although others assume that this form of damage can be remedied quickly utilizing such sealants and swift repairs, water can go unnoticed. If the roof is broken, water will reach the roof and the ceiling, drop down the walls and even enter the electric outlets.
#Hail storms are infamous for creating irritating dents in the roof of RVs. Sections and branches are often parked in campgrounds from trees that land on the roof. Intensive heat and sunlight increase your RVs probability of delaminating the gel and painting work.
#Water penetration may do a great deal of harm to RVs as it could result in broad red and mold growth unchecked, sometimes total removal and costly replacement of material.
