Ways To Inspect Any Water Leaks Or Damage

Applying Flex Seal to your RV or Trailer Roof | Season 3 Ep 55

To inspect any water leaks or damage on your rubber roof, you need to do a physical check on the entire roof the roof seams, and around the openings.

Make sure to search for any cracks or gaps, especially with the sealed parts. Once its done, check the interiors ceiling, wall, and floor and look for any water damage or leak stains.

This is especially important after weather events like hail. You can read more about if hail will damage your roof here.

After that, use a seal-tech machine that produces pressure on the inside of the RV unit. Then, go back to the roof and spray soap and water solution on the gaps or cracks you found. If bubbles show up, that confirms the area has holes and would cause leaks.

Make sure to thoroughly clean the area that you would seal and dry up using a sponge or clean cotton. This helps the seal product adhere to the surface.

If a seal-tech machine is unavailable, you can use other equipment that blows air pressure within the interior such as a furnace blower.

Other Important Factors To Consider

What is an RV Roof Coating/Sealant?

An RV roof coating or sealant is a product that plays a major role in your RV roofs maintenance. Applying it regularly is crucial in providing the roof in your RV a new shine. Remember that a new roof coating is needed at some points in your RV roofs life.

This especially holds true for rubber roof, which might become chalky. It might also wear off gradually with time. With the help of a highly reliable RV roof coating or sealant, you can revive the good condition and look of your RV roof.

Another thing that this coating or sealant can do is to prevent water and other forms of moisture from penetrating your vehicle. With that, it can help properly secure all the things and features found in your roof. You can even use it around skylights, roof vents, and any other parts that need to be secured.

How Does an RV Roof Coating/Sealant Work?

An RV roof coating or sealant works in extending the life of your RV roof. It does so by lessening the transfer of heat into the roof. It also works in reducing thermal shock caused by the thermal contraction and expansion of the RV roofs membrane.

Furthermore, it can help mitigate leaks. You can also expect most roof coatings, especially the reflective ones, to lessen energy costs while also improving your roofs aesthetics.

Types of RV Roof Coatings

The problem is that it is a bit costly and tends to add more weight to your roof. In addition, it is not that easy to install.

Rubberseal Liquid Rubber Protective Coating

What truly blew me away about this elastomeric roof coating is how extremely efficient it is at reflecting sunlight and the damaging UV rays that come with it.

In truth, this coating prevents most of the suns heat from getting into the RV. Also, whatever amount of heat the roof gets, the coating lets it dissipate quickly.

Because it no longer gets too hot inside the RV, I find myself not turning up the air conditioner as often as before. It helps lower the cost of operating my RV significantly.

Furthermore, the finish comes on thick and is very elastic. So, the liquid RV roof coating will not have any trouble bending and flexing along with the RV roof. It means that the coating will not tear, puncture, or rip apart easily, thus keeping your roof in top condition.

Another thing that I like about this product is how thick its consistency is, allowing me to use it as an elastomeric seal. Once painted over seams and little holes and tears on the roof, it will cover all of them effectively. You may still need to go over some areas with proper sealants, but overall, it handles everything fine.

  • Allows heat to dissipate quickly
  • Keeps the inside of the RV relatively cool even on hot days
  • Highly elastic coating, which can stretch and bend with the roof
  • Thick consistency, offering help in plugging up holes and seams on the roof
  • Takes some sunny days to cure completely

Best For Roof Edges: Dicor 501lsw

If you only need to seal small areas along the edges of your RV roof, the Dicor Corporation Self-Leveling Lap Sealant is much more affordable than a paint-can style sealant.

And itll also work well to seal around vents, air conditioners, roof antennas, and anywhere else that water may leak into the substructure of your RV roof.

This sealant is best suited for EPDM rubber roofs or rubber TPO, but it will also adhere strongly to aluminum, mortar, wood, vinyl, galvanized metal, fiberglass, and concrete.

It is compatible with other Dicor Products and may be used after their Cleaner/Activator and EPDM Rubber Roof Coating system, respectively, for a full roof sealant solution.

Youll need a caulking gun to apply this sealant and it has self-leveling properties to help with a smoother, more complete seal where applied.

Each tube contains 10.3 ounces of sealant and that small quantity will mean you might need a good number of tubes to seal the edges or seam around your entire RV.

For example, one user used a total of five tubes to seal the edges around a 13-foot trailer.

So, extrapolating that number out, youd need 10 tubes for a 26-foot RV and a minimum of 14 tubes for a 33-foot rig.

Furthermore, this sealant is rated to be reapplied every three months or so for maximum effectiveness.

This means that you might need to spend more time applying this sealant than youd need with other solutions.

More importantly, this coating can twist, flex, and even stretch and contract. Unlike other roofing materials, this coating will not freeze and crack even in sub-zero weather.

This liquid roof RV coating is also virtually impervious to water. Although this RV rubber roofs coating might look porous when dried, it is still a watertight membrane that spans the entire roof.

A layer of rubber roof sealant will also help prevent any warping from the heat and will save you money in the long run by helping to prevent costly RV roof repairs.

As an added perk, youll likely end up using less power, since you wont have to crank up the air conditioning or heating.
  • Reduced wear and tear. The roof surface of your RV takes a real beating over time. With repeated exposure to the elements, your RVs roof can start to show signs of wear and tear. Having rubber roofing atop it helps keep that wear and tear to a minimum.

Kevin Means said:Yes, do yourself a favor and don’t use silicone. Look for a product called Dicor. You can find it at just about any RV store and I think Home Depot carries it. It’s self-leveling and specifically designed to do what you’re trying to do. It stays pliable, is pretty easy to apply and once cleaned, you can apply it over itself. It’s also not real difficult to remove if you need to. Eternabond tape is also good stuff – sticks to just about anything but is a bit more difficult to seal around things than Dicor.Kev

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, on 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. Ive 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.
