Can Flex Seal Be Used On Roof Shingles

Things To Remember When Using Flex Seal For Roofing


Flex seal is not a replacement for your roof or gutters.

It can only seal small cracks and holes, while it will do nothing to repair missing shingles or large gaps in the roof. They should be fixed by professionals before using flex seal on them .

Do not use flex seal on the roof in extremely hot or cold weather, when rain is expected to fall, or when it has rained recently.

Using a flex seal on your roof before painting it will keep the paint from sticking properly to the surface.

Flex seal also needs to be applied directly onto clean surfaces, so any old paint layers should be swept away before applying.

Every can comes with a brush attached to the lid, and while many roofs only require it to be applied in small areas, you may want to get extra brushes for any larger jobs.

Additionally, some users agree that using a roller is also easier than using a brush .

This can be done by pouring a small amount of water over the area you suspect the hole in your roof is located and checking for the leak underneath. Do a small area at a time, to really pinpoint the cause of the leak.Be sure to check any areas where the roof comes to a juncture, or where there are any added items, such as exhaust pipes.

Roll Or Brush Liquid Rubber Onto Your Rv Roof

It is time to apply a generous amount of liquid rubber to the leak area and the surrounding surface.

As a rule of thumb, it is best to apply liquid rubber over a surface area that extends at least six inches in each direction away from the primary location of the leak.

If your leak is on a flat part of your roof, this should not be a problem. But if the leak is right next to a roof vent, air conditioning unit, or the edge of your roof, it may not always be possible. In these cases, you will need to use your brush to apply liquid rubber.

For leaks on an especially hard-to-reach location, you should also consider switching to Flex Seal Spray or Flex Shot for an alternative application method.

Regardless of the product you wind up using, however, the intent, is to apply a thick enough layer to completely seal the leak from future water ingress.

When May I Want To Use Flex Tape

Good question. And at first we were a little confused about what we would use it for too.

Flex Tape is a faster, simpler solution than either of those, and the results last longer too. If you have a leaky pipe, just stick it on, no need to dry or clean or line it up perfectly.

Flex Seal On Rv Awning

Flex Seal- Does it work? 6 months on a roof – results surprised me

This product is a good sealant to use when you have a water leak problem on your RVs awning. It does a great job sealing the problem and keeping the water out. Again, the secret to this success is to follow the instructions on the can.

Now, with that said there is a slight word of warning. Awning fabric is not as thick as other materials used on your RV. What this means is that when you spray or brush on Flex Seal, you may see some bleed through and have the awning stick to itself when you go to roll it up.

One solution to this additional problem is to cute a large enough piece of clear plastic sheet off a larger section. Once that is done, you can tape this smaller section underneath the torn spot.

Then you can apply the Flex Seal and let it dry. The clear plastic sheet should stop the bleed through and keep your awning from sticking together after you roll it up. Small little tricks like this should save you from giant headaches and more costly repairs or replacements.

Flex Seal Is Not Uv Stabilized

Flex Seal is not UV-stabilized, which means that its protection is highly unlikely to last in the harshly sunny environments that most RVs experience.

UV protection is a very important part of any product used to seal any part of your RVs roof. Without UV protection, the product will dry out and crack, and the protection you think youve established will be gone, leaving your rig susceptible to leaks that you may not even be aware of until significant damage has occurred.

There are hundreds of complaints online about Flex Seal cracking and failing, and its lack of reliable UV stabilization is likely partly to blame.

Remember that RV manufacturers are well aware of the importance of UV protection and are unlikely to recommend the use of any product that doesnt offer it, particularly for an RV roof.

    Benefits Of Sealing Roof Leaks With Flex Seal

    Flex Seal Works! Leaking Roof!

    Flex seal protects the surface from UV rays, rust, and corrosion. It can also be used on dry and wet surfaces and does not crack or shrink after application. Unlike other sealants, it does not sag, crack, or peel when exposed to extreme weather conditions. You can use it to seal gutters, cracks, and other small roof leaks quickly. When applied onto the surface, the liquid rubber creates a hardened layer in a short period, making it an effortless task. It starts as a thick liquid that can be rolled or flattened out with a brush. This turns it into a sturdy, flexible rubber.

    The good thing about flex seal is that it is eco-friendly and non-toxic to the user. Some flex seals are waterproof and can last for years. The only downside to flex seal is that some variants have a strong smell thus should be used in well-ventilated areas. Flex seal that is purchased in cans can be quite messy for one application.

    If your trips to the roof seem like a daily or weekly task, there could be a serious issue that cannot be fixed with a flex seal. Some roof leaks are widely spread and probably need to be checked by a roofing expert. Climbing on the roof on your own could also be risky depending on your skill level and type of roof. It is always important to seek expert advice from a roofing professional to save time and reduce repair costs to a minimum.

    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 RVs 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.

    It is important to note that this second type of repair should not be considered permanent. It is a repair designed to fix the leak and buy you time to plan and schedule a permanent roof 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 which 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 condition 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.
