How To Use Flex Seal For A RV Roof
Understanding how to use Flex Seal for an RV roof is crucial for any RV owner who wants to maintain their vehicle’s longevity. Flex Seal is a liquid rubber sealant in a spray can that can prevent or repair any leaks on the RV roof.
- Inspect the RV roof: Thoroughly check for signs of damage.
- Clean the RV roof: Remove loose debris, dirt, and rust.
- Prepare Flex Seal: Shake the can vigorously for a minute.
- Application of Flex Seal: Hold can 12-14 inches away.
- Regular checks: Inspect the roof regularly for new damage.
- Maintenance: Clean sealed areas regularly.
Air, heat, and rain can cause the RV roof to weaken and eventually leak.
A leaky roof is one of the most common problems with houses. The reasons can range from bad building materials by the builder to the extreme climatic conditions prevailing in a region.
The cost incurred due to severe roof damage in a US household can easily exceed $ 6,500.
RV roofs don’t usually cost as much to repair, but they can still be expensive, so you might want to consider fixing minor issues yourself.
This guide will provide you with the necessary steps and precautions you need to take when using Flex Seal. From surface preparation to proper application techniques, each aspect of the process will be covered in detail to ensure a successful outcome.
Why RV Roof Damage Occurs
If you are traveling or staying in your RV in the US, the vehicle is expected to be subject to both warm and cold conditions.
It’s not uncommon for the weather to be wet and cold during winter. If wet weather occurs before freezing temperatures, an interesting phenomenon occurs.
Water, of course, expands as it freezes. If water has permeated between the gaps of a roof seal during a recent rain, and then the temperature subsequently drops, this water will expand and push against the roof seals.
This contraction and expansion could lead to leakage and letting the icy water enter. Flex sealing can be used to avoid such a situation. It is easy, quick, and works.
How To Use Flex Seal On An RV Roof
As durable as Flex Seal products are, they aren’t the answer to everything. It has its uses and benefits.
Before purchasing Flex Seal products, verify that they will work on your RV’s roof.
These sealants are primarily compatible with various substrates, including fiberglass, metal, EPDM rubber, and thermoplastic olefin (TPO).
You can probably use Flex Seal on your roof unless it’s made of something else.
Consider the extent of the damage following. Flex Seal is great for patching up punctures and tears of any size. It’s great for patching up small leaks and cracks because it creates an impermeable seal.
To what extent is Flex Seal suitable for RV roofs of varying dimensions? No.
Large areas of surface are not suitable for use with Flex Seal. It works better for addressing minor flaws. It will lose some efficacy if it is spread too thin and over too large an area.
Use as much as you need if it’s your last resort or an emergency. You should know that this is not its intended use.
Keep a bottle of Flex Seal in your RV maintenance kit in case of an emergency. Even if this isn’t the best long-term solution, it will help you repair the RV roof quickly and prevent further damage.
These items are effective temporary fixes that will keep your RV safe and dry until you can get a repairman.
1. Search For The Leak
The first and foremost step includes doing an inspection of the roof and scanning out or identifying the areas where there are leaks.
The scanning can be tedious as it involves taking up a small area of a roof and then looking for holes and the possible reasons behind the holes or gaps in the roof.
2. Clean The Area
The next step involves clearing the area where there is a leak so that the area becomes visible clearly and the flex seal can work properly on the area.
Utilizing a high-quality RV roof cleaner comes with a plethora of advantageous outcomes. They contribute to repairing the damage caused by Mother Nature and prevent further damage from being caused by environmental pollutants.
-
Durability
Roof cleaners eliminate loose dirt, grime, bugs, pollutants, and other road grime, all of which can shorten the lifespan of your RV roof and cause it to become less watertight.
Mainly if it is left on there for a significant amount of time, you can extend the life of your RV and keep it in good condition by removing all of these contaminants from it and keeping it clean.
-
Protection
Many products can add a layer of protection to your recreational vehicle’s roof, which will prevent it from being damaged for an extended period by damaging rays, water, or environmental pollutants.
Many of them come equipped with a UV blocker that works to preserve the pristine condition of your roof.
The gentle nature of a good roof cleaner is another essential quality to look for in a product of this kind. Household cleaners used regularly can erode your roof if they are too abrasive or contain harsh chemicals like bleach.
If you use a cleaner specifically designed for your kind of roof, like an EPDM rubber roof, there is no chance that you will cause any damage to it.
Ensure that no leaves, oil, or anything else can get attached to the roof after the sealing treatment. For a perfect finish, it is necessary to clean the surface properly.
3. Shake The Can
Shake the flex seal can. Shaking it vigorously for over a minute ensures that it will function optimally. Hence, shake it well before using it on the target area.
4. Keep on Spraying
Now comes the time to spray it with holes and leaks in the area.
The person spraying should know that the area on which it is sprayed gets adequately covered and that not even a single portion is left. Ensuring the affected area is completely covered will ensure a long-term fix and no further leaks can occur.
Why Should You Use Flex Seal On Your RV Roof
Advantages:
- It allows economical treatment of the otherwise costly affair. Repairing a roof is way more costly than flex sealing the roof.
- It delivers results within minutes of being applied.
- It is readily available at various retailers and is perfect for quick fixes while on the road until a more permanent solution is available. Fully repairing a roof cannot be done overnight using other means, and it can cost a fair amount of money.
Disadvantages:
- Flex seal cannot repair a whole roof. When there’s a lot to repair, look to other options.
- Weakening of the wall leads to leakages. If ignored consistently, it could lead to more severe consequences. Therefore, it must not be taken lightly.
- Flex seal is only a temporary solution to the problem.
How do you know if Flex Seal has been applied correctly?
An actual test is passed by flex seal when the leakage gets blocked, and the walls supporting the roof do not show signs of leakages. The perfect example of flex seal working is when the holes are filled in, and the problems faced previously are resolved.
It is an errand work and can be completed by the person on any weekend. Unlike full-time repair, a flex seal can be done by you instantly, and the problems can be fixed quickly.
The patchwork can then be covered with the color of the rest of the roof, and your roof is ready to go.
What Kind Of Roof Materials Can Be Repaired With Flex Seal
Knowing the type of RV ceiling flex seal that can be repaired is good.
This is because of the different characteristics of the material and the ingredients used.
A clear understanding of the two is required. There are two types of roof seals for RV of rubber roofs. These materials are designed for RVs and are not often found in houses. They can be of the following types:
EPDM
If the RV is made up of an EPDM rubber roof, it is unlikely to need repair for ten years after installation.
You can get this synthetic rubber in liquid or sheet form, and it was developed with roofing in mind. It can be applied as a liquid and then dried to a semi-solid state for a malleable, watertight seal.
EPDM sheets undergo a curing process that reduces their pliability but increases their durability.
The typical color of this material is black, though many liquid products dry to a white finish that provides increased UV protection and other advantages.
The owner must clean the roof periodically with clean water to keep it working correctly. However, there should be no use of chemicals and other reactive elements that could react with the roof and cause damage to it.
It has a long life span and is very resistant to wear and tear.
TPO
This low-priced synthetic material is a laminated membrane. You can use glue or another roofing adhesive to secure this material, or you can use mechanical screws. Heat welding can secure seams and other details, but glue and sealing can also be used.
To increase its strength, this material can be mixed with fiber reinforcements; however, this can make the material more rigid, which can pose challenges during installation. Such roofs have more plastic content than rubber, which makes them look shiny.
They are more stable and long-life-sustaining than the EPDM roofs. Such roofs can be washed with soaps and are very resistant to wear and tear.
Where Should You Not Use Flex Seal?
It’s essential to highlight that Flex Seal should not be applied to foam materials. The chemical composition of Flex Seal may have adverse reactions with some types of foam, causing the foam to warp or even dissolve.
While Flex Seal is a versatile sealing solution for many materials, the potential for adverse interactions with foam makes it unsuitable for such applications.
Therefore, it is crucial to carefully consider the material composition of the surface before applying Flex Seal to avoid any potential damage.
