This detailed article will get you through all the minor and major details of RV roof maintenance. Let’s dig in to learn how or when your RV roof should be resealed and some recommendations to help you prevent any significant damage.

How Long Will an RV Roof Coating Last?

RV roofs suffer extreme weather conditions like rains, snowstorms, and UV rays in hot weather. Due to these conditions, your RV roof or its coating often gets damaged. It can lead to water leakages and expanded walls or interior material.

Nothing beats a quality roof coating when it comes to protecting your RV roof from the elements. Depending on the roof coating you use, you can expect it to last anywhere from 10-20 years or more! Let’s take a closer look at three common types of RV roof coatings – rubber, silicon, and fiberglass – and how long they last.

Rubber Roof Coating

A rubber roof coating can last about 20 years or more if properly maintained. Rubber roof coatings are a great option for RV owners who want to protect their roofs for the long term. These coatings are durable and waterproof, withstand years of sun exposure without fading or cracking.

For RV rubber roofs, the longevity of your coating depends on a few factors. 

  • First, you must ensure that the roof is properly cleaned and prepped before the coatings are applied. If not, dirt and debris can get trapped under the coating, leading to premature deterioration. 
  • In addition, regular maintenance and timely repairs can help your coating last longer. That includes checking for any signs of damage, such as cracking or peeling, and addressing them as soon as possible.

Fiberglass Coating

Fiberglass coatings are a popular choice for RV owners because they’re easy to apply and relatively inexpensive. These coatings provide a strong barrier against the elements and are resistant to cracking and fading. A fiberglass coating can easily last 20 years or more if properly maintained.

To keep your coating in top shape, make sure to clean it periodically and look for signs of wear or damage. The longevity of fiberglass RV roof coating is even greater because fiberglass is a very durable material. It’s also fairly easy to maintain, requiring no special cleaning or treatments. 

That said, you will want to make sure that your fiberglass roof is free of dirt and debris regularly. This helps prevent scratches and other damage that can lead to roof leak and moisture buildup, which can affect the longevity of your coating.

Silicone Roof Coating

A silicone roof coating allows the original roof to last up to 50 years rather than 20 years when properly applied and maintained. To keep your roof in good shape, it’s important to reapply the sealant every five to seven years

This will help protect against UV damage, roof leaks, and other damage that can occur over time. It’s also important to inspect the sealant for any cracks or holes, as these can lead to moisture build-up and further deterioration of your roof.

Applying a silicone coating to your RV’s roof will provide numerous benefits. 

  • One of the main advantages is that it can protect from UV damage, which can help preserve and extend the life of your roof. 
  • It also helps reduce or eliminate leaks and prevent other forms of water penetration.
  • Additionally, a silicone coating will act as an insulation layer, helping to keep your RV cooler in the summer and warmer in the winter.
  • Finally, a silicone coating is easy to apply and maintain, making it a great choice for RV owners looking for reliable long-term protection. 

The experts often recommend a yearly re-coating to keep your roof safe and sound. However, regular scans must be made to look for minor problems with the top. It will increase the lifespan of your RV and keep you comfortable despite the weather conditions. Silicone roof coatings are very effective and last longer than others.

No matter what RV roof coating you use, it’s important to take good care of it. Proper maintenance can not only extend the life of your coating but also ensure that your RV’s roof remains in peak condition for years to come. 

RV Roof Maintenance

RV roof maintenance is essential in keeping it safe and beneficial. Regular maintenance is the key to saving yourself from big trouble. Your maintenance bags must have a cleaning kit, liquid rubber, sealant tape, seam roller, and all the necessary tools. We will discuss below in detail how and when maintenance should be done.

When To Check for Cracks?

Monthly checkups work excellently when checking for cracks. These can lead to significant damage and can make your life hell in rainy weather in an RV. So, always pay attention to cracks and fix them quickly. Checking cracks during cleaning or washing your RV is also a fantastic idea.

You must remain conscious of cracks if you live in an extremely hot or rainy or moderate area. It would help if you kept checking every time you noticed anything unusual. Loud rain voices may also be a sign of a crack. 

How Often Should You Reseal Your RV Roof?

As mentioned above, you should reseal your RV every year. It also depends on your area’s weather conditions and RV use. The type of sealing can also make a difference in your resealing time. A good silicone sealing can last longer than others.

How To Maintain an RV Roof?

The first thing required for RV roof maintenance is having the necessary equipment.

Rubber Roof

Rubber roof maintenance is quick and simple. The following steps should be taken regularly to ensure that your rubber RV roof is properly maintained:

Clean the Roof 

Rubber roofs should be cleaned every 3 months but may vary depending on how often you use your RV and how exposed it is to harsh weather conditions such as heavy rain or snow. Avoid cleaning it with a harsh surface or petroleum liquids, as it can be harmful. 

Clean it with warm water and soft detergents. Remove the affected coating area and replace it gently. It will keep your roof safe for a much longer time.

Inspect for Damage

Regularly inspect your rubber RV roof for any signs of damage or wear. Look for cracks, punctures, or other rubber wear signs. If you find any damage, it should be addressed immediately to prevent further deterioration.

Protect from UV Rays

Rubber RV roofs can be susceptible to sun damage if not properly protected. Investing in a quality roof coating can help protect your RV’s rubber roof from UV rays and extend its life. Make sure to reapply the coating every two years or as necessary.

Check Seams

Rubber RV roofs are held together with seams, which can dry out over time if not properly maintained. Regularly check these seams for any signs of cracking or wear and tear and replace them as needed.

Seal Holes

If you find any holes or punctures in your rubber RV roof, make sure to seal them with a quality rubber sealant as soon as possible. This will help prevent water from seeping into the RV and causing further damage.

Following these steps regularly will help ensure that your rubber RV roof is properly maintained and free from damage.

Fiberglass Roof

Fiberglass roofs require little upkeep except for the occasional liquid brush or mop. An acrylic or gel coating can restore the top to its original condition if a fiberglass roof has cracks and pinholes that indicate wear.

Here are some tips on how to maintain a fiberglass RV roof:

Clean the Roof

Regularly remove dirt and debris from the RV’s roof surface. You can do this with a soft brush and mild detergent. Be sure to rinse the surface thoroughly after cleaning, as soap residue may cause streaking or staining on the fiberglass.

Key Takeaway: With all of this in mind, there are still plenty of great reasons to make aftermarket modifications to your car. Just be sure to do your research and understand the potential risks before making any changes.

Inspect for Damage

During your inspections, look for signs of damage, such as cracks, dents, and other imperfections. If you notice any, contact a professional for repairs.

Wax the Roof 

Waxing your RV’s roof helps protect it from UV rays and other environmental elements. Look for a wax specifically designed for fiberglass roofs and apply two to three coats every six months.

Check Seals

Ensure all the RV roof seals are properly sealed. It ensures that moisture and dust don’t get in, which could damage your RV’s interior.


If you notice any cracks or other imperfections in your fiberglass RV roof’s caulking, re-caul it as soon as possible to prevent further damage.

Silicone Roof

Maintaining a silicone RV roof is an important part of extending its lifespan. Silicone roofs are known for their durability and ease of maintenance, but there are still some steps you can take to ensure your roof remains in top condition.


First, inspect the roof’s entire surface regularly for any signs of damage or wear. Check for cracks, punctures, and other imperfections. If possible, use a ladder or binoculars to check for damage on the upper sides of your roof. Make sure to patch any holes immediately using silicone caulk gun to prevent further damage.


Second, clean the roof often with a soft brush and warm water mixed with mild soap or roof cleaner. You should also use a soft sponge to remove dirt, mildew, leaves, or other debris from the roof surface. Make sure to rinse thoroughly with clean water after cleaning to prevent soap residue buildup.

Apply Sealant

Third, apply a coat of silicone sealant every two years or so on the entire roof surface. It will provide an extra layer of protection and can help to maximize the lifespan of your silicone RV roof.

Regularly Check For Leaks

Finally, always check the seams and perimeter of the roof for potential leaks. If you notice any water seeping through, patch it up with a silicone sealant as soon as possible.

By following these steps, you can maintain your silicone RV roof and help to extend its lifespan. Taking good care of your roof will keep you safe and dry during your RV adventures.

When Should You Reseal?

You must consider revealing your roof whenever the protective coating is damaged or affected. You may also consider resealing in case you face any accidental damage. Usually, it would be best if you did re-coating every year, but it also depends on the weather conditions you keep your RV. RV sealings might work longer if you maintain them properly.

Sealant Failure

Plumbing material, air conditioner unit, and vents require sealants. Ensure using suitable adhesives to prevent significant loss. Sealant failure is one of the biggest problems. Generally, tape or liquid sealants are used for minor repairs. Decided on sealant depending on your roof surface. Its failure is the primary reason you should consider resealing. 

Sealant Age

Everything created has an expiry date, and sealants are nothing different. Sealants can work fine for up to 1 year. After that, you usually face problems as they are damaged, and you must consider re-coating after that.

Sealants may even work fine if you drive less and carefully, but if you are off-road and have faced troublesome weather, the sealant’s age may be less. Keep inspecting sealants regularly to avoid any trouble.

Malfunction of Screws

Screw malfunctioning is another reason you should reseal. The screw on the roof may get rust, and the rust can eventually spread and damage the roof. The accidental opening of a screw can also cause leakage in the ceiling. It is another big reason to consider resealing if you have started facing this issue. 

Accidental Damage

Accidental damage is the reason why most RVs need resealing. Hailing or stormy rains are the primary cause of unintentional damage to RV sealing. Tree branch collisions or overweighting the roof can also be the season of re-coating. 

These accidental damages are widespread with travel trailers. These can lead to significant leakage if you have left them untouched. Try to get them repaired as soon as possible after the damage.

Sealing an RV roofing is vital to keeping your recreational vehicle in great shape. It will help protect your RV’s interior and exterior from damage, prevent water penetration, and keep you comfortable camping. Here are some tips on the best way to seal an RV roof.

Preparing the Roof

Before applying any type of sealant, properly prepare your RV roof for the job. This should include cleaning and drying the surface completely and repairing any damage before beginning. You’ll also want to use a putty knife or scraper to remove any dirt, debris, or old sealant and ensure a clean surface.

Can I Walk On The Roof Of My Travel Trailer?

Many people wonder if walking on the roof of their travel trailer is safe. It is important to understand that walking on a travel trailer’s roof can damage or break the roof and should be avoided as much as possible.

Potential Damage From Walking On The Roof

When someone walks on the roof of their travel trailer, it can cause two main forms of damage. First, the person’s weight can cause the roof to bend, creating a stress point that could lead to cracking or breaking. 

Second, walking on the roof can eventually wear away any protective coating on the surface, causing water and other elements to get into the roof. This can eventually cause it to deteriorate, leading to costly repairs and replacements.

Alternatives To Walking On The Roof

Rather than walking on the roof of your travel trailer, a few alternatives should be considered first. 

  • One option is to use a ladder or step ladder to reach the roof safely, avoiding any potential damage. 
  • Another option is to use a telescoping pole with a hook on end, which can be used to access items on your travel trailer’s roof without putting additional weight or pressure on it. 
  • Finally, you can enlist the help of another person to assist you in accessing items on the roof of your travel trailer, ensuring that there is no additional weight or pressure put on the roof.

How Much Weight Can an RV Roof Support?

An RV roof is designed to support a certain amount of weight. As a general rule of thumb, however, you should work off the assumption that the upper limits are around 250 lbs. and take precautions from there.

The amount of weight that can be safely supported depends on several factors, including the type of RV, the materials and construction of the roof, and the roof’s condition. It is important to know how much weight an RV roof can support so that it is not overburdened and damaged.

Type of RV

The type of RV has a significant impact on how much weight the roof can support. Class A motorhomes and travel trailers typically have roofs made from fiberglass, while fifth-wheelers and toy haulers tend to have metal roofs.

Fiberglass roofs are typically designed to support more weight than metal roofs, so a heavier load can be placed on them without worrying about damaging the roof itself. Class C motorhomes usually come with a combination of both types of roofing material, allowing for greater flexibility in terms of weight capacity.

Materials and Construction

The RV roof’s materials and construction also influence how much weight it can support. Roofs with thicker layers of material are typically able to handle more weight than roofs with thinner layers, as they are better equipped to resist damage and wear. 

Additionally, different types of screws, rivets, and sealants used during construction can affect the roof’s weight capacity, as can the number of layers used in the construction process.

Condition of Roof

Finally, the condition of the RV roof affects how much weight it can support. A roof that is in good condition and free from any visible damage should be able to handle a greater load than one that has been damaged or is showing signs of wear and tear. It is important to inspect the roof regularly to ensure it is in good condition before adding any extra weight.


How much does resealing an rV roof cost?

The cost of resealing an RV roof can vary from 200 to 800$. Doing it yourself will cost around $200, but getting it done by a professional expert may cost up to 800$-1000. The price may also vary due to other reasons, like the roof’s size and the material used for resealing.

What to use for rV roof sealant?

Liquid and Tape sealants are primarily used and are very effective in this regard. RV roof sealants selection should be made carefully depending on the size of the damage and the type of built in material of the roof.

Can you seal an RV roof in cold weather?

It is not recommended to seal an camper roof in cold weather, as the coatings may not be able to dry properly. This can lead to premature wear and tear, which could potentially cause damage to the roof itself. 

If your area is expecting freezing temperatures or precipitation, it is best to wait until the temperature rises above 50°F before you seal the roof. Additionally, it is important to store your coatings at temperatures between 40˚F – 90˚F before application. 

How long does RV roof sealant take to dry? 

Generally, the sealant takes 24-48 hours to fully set and cure. This curing time can be affected by environmental factors such as humidity, temperature, and exposure to direct sunlight. It’s important to check the instructions on your RV roof sealant for specific drying times, as they may vary from product to product.

Final Considerations

RV sealing should be done every year. Regular checkups should be made monthly. A significant inspection should be made twice a year. Minor repairs should be done after every regular checkup and assessment. This maintenance will help you in keeping your RV always ready.

A leaking roof can ruin your trip’s comfort and fun, so always take note of these preventive measures. Well, now that you know all the flaws and how often you should reseal your RV, you can easily maintain it. You will also save money by preventing significant repair costs and enjoy your RV.
