Is Flex Seal Good For RV Roofs?
If you’ve ever tried to make home repairs or worked on an outdoor project, you may be familiar with the Flex Seal family of products. These include a range of adhesive tapes, sealants, and sprays that are tough and waterproof. If your camper’s roof has started to leak or tear, you may be wondering, “Is Flex Seal good for RV roofs?”
Although the Flex Seal family has some great products, this isn’t a simple yes or no answer. There are a lot of angles to this question that have to be considered such as the RV roof material, the type of damage you’re dealing with, and the size of the damaged area. Flex Seal won’t make the problem worse, but it might not always be the best product to turn to.
Let’s explore this issue further below. Some people swear by Flex Seal as a cure-all product, while others have been unimpressed. It really all comes down to the problem you’re dealing with and how long you need the solution to last.
When to use Flex Seal
Although Flex Seal products are quite hardy, they aren’t a perfect solution to every problem. There are times and placed to use it.
First of all, make sure your RV roof is compatible with Flex Seal products! Most of them will be because these sealants work with fiberglass, metal, EPDM rubber, and TPO. Unless your roof is made with some other material, you should be safe to use Flex Seal on it.
Next, you need to consider the size of the damage. If you’re dealing with a small rip or hole, Flex Seal is a wonderful solution! It’s perfectly suited to mending small areas and will form a watertight seal. But is Flex Seal good for RV roofs of all sizes? No.
Flex Seal isn’t designed to be used over large surface areas. It’s better for fixing small imperfections. If you spread it too thin and over too wide of an area, it will lose some of its effectiveness. If it’s the only thing you have on hand and it’s an emergency, you can use as much as you need to. Just be aware that this isn’t what it was designed for.
As an emergency solution, it’s a good idea to carry a container of Flex Seal in your RV repair supplies. This may not be the best long-term fix, but it will help you patch cracks and holes in the RV roof before they can get worse. These products have proven to be great stop-gap measures that will keep your RV secure and dry until you can get professional help.
Best types of Flex Seal to use for RV roofs
If you’d like to keep some Flex Seal products on hand for emergency roof repair, that’s a good idea. There are different forms of Flex Seal, and some might be better than others for your situation. There are 4 main products that are useful for RV roof repair. These include Flex Seal Liquid, Flex Seal Spray, Flex Shot, and Flex Seal Tape. Each form has its own pros and cons, so let’s explore each of them a bit!
Flex Seal Liquid
This product is a thick, dark liquid that can be easily spread over an RV roof. Once it sets, it will form a waterproof rubbery seal. If you need a stop-gap product that can be used over larger areas, Flex Seal Liquid is your best bet. It’s easy to apply and comes in large quantities.
Flex Seal Spray
The Flex Seal Spray is essentially Flex Seal Liquid in an aerosol can. It’s easy to apply to hard-to-reach surfaces and forms a similar seal. It can be a bit harder to get a thick seal with this format, but it’s an easy way to make a surface much more water-resistant.
Flex Shot is essentially Flex Seal’s version of caulk. It comes out in a thick, easy-to-control flow that you can guide along cracks, edges, and corners. This product might be best for interior fixes or clearly-defined roof cracks. It doesn’t spread quite as easily as the liquid or spray, so you should only use Flex Shot on small areas.
Flex Seal Tape
Finally, we have Flex Seal Tape, which might be the most well-known product of this company! It was famously used to mend a boat that had been sawn in half, so you can rest assured that this tape is strong and waterproof.
Obviously, this tape is best for small fixes as well. It would take a lot of time, effort, and money to cover an entire RV roof in Flex Tape, and you might have a hard time getting it off when you take it in for professional repairs. Because it is so strong, it has the potential to rip up the roof material once it is removed, so it may cause more damage in the long run.

Flex Seal Alternatives
Some people have had stellar experiences using Flex Seal for all their roof problems, while others have found that it doesn’t suit their needs. Luckily, when it comes to roof repair, Flex Seal isn’t your only option. There are some sealants that were made specifically for mending and protecting RV roofs!
For instance, you may want to consider bringing along some RV Roof Magic. This liquid product was specifically designed with RV roofs in mind. It doesn’t require a primer, dries within hours, and provides stellar waterproof protection. You can also use it over large surfaces, not just for small fixes.
Other good products include:
- Dicor Self-Leveling Lap Sealant
- Sikaflex 715 Semi Self Leveling RV Roof Sealant
- Liquid Roof RV Liquid EPDM Coatings
So now we know that Flex Seal is good for RV roofs, but it’s not always the best option. There are other products that you may want to keep on hand specifically for roof repair, but Flex Seal products are great for many purposes! They’re tough and versatile, so it never hurts to keep some on hand.
