How Often Should You Seal Your RV Roof?

Updated on January 28, 2024

Sealing your RV roof is an important part of maintenance that helps to prevent leaks and water damage. But how often should you do it? The answer depends on several factors, including the type of material your roof is made from, your climate, and how frequently you use your RV.

Generally speaking, it’s recommended that you seal your RV roof at least once a year or every 18 months. However, if you frequently travel through areas with extreme weather conditions or store your RV outdoors for long periods, you may need to seal your roof more often.

During summers, many people travel by road in their RV to discover new places in the comfort of their own rolling homes. However, before you start traveling for long distances, it is necessary to have a vehicle check-up. 

This is important if your RV has sealing issues, leakage issues, flat tires, etc. So keep on reading if you want to discover how you can seal your RV roof. 

Why Should I Reseal My RV Roof?

There are many benefits to resealing your roof regularly. Sealing it against water and sun damage is vital to avoid early wear and tear in your RV. 

#1 Prevents Leaks/Drafts

Cracks and spaces in your RV’s roof will allow air and water to enter your RV, ruining the interior.

Moreover, due to the drafts in the RV, the cooling and heating system of the vehicle will have to work extra hard to maintain the temperature. This will eventually cause the heating and cooling system of your RV to wear out more quickly. 

So if you want to help protect your RV from leaks, use rubber RV coating to seal your roof. 

#2 For Comfort

Nowadays, more people prefer buying or renting RVs for their road trips instead of getting tents or campers due to their comfortable environment. 

Unfortunately, though, if your RV roof is leaking, you are not going to get the sleep you need in an uncomfortable environment. 

#3 Extends the Roof’s Lifespan 

All motor vehicles are designed to withstand harsh weather conditions such as snow, rain, hail, etc. Similarly, an RV’s roof protects you from extreme weather conditions. 

However, it does not mean the roof won’t wear out over time. You can extend the life of your roof and your vehicle in general by coating it with sealant regularly. 

#4 Fewer Repair Bills

The lesser the problems, the lesser the costs of repairs will be. Everyone should know that the earlier you find a problem, the cheaper it’ll be to fix it. 

The same goes for RVs. If you find cracks or drafty places, you must seal them immediately. Plus, a regular roof inspection is crucial, so you don’t miss out on catching minor problems in your vehicle. 

A small leak that goes unnoticed can grow and cause potential water damage to your motorhome. 

#5 Regulation Of Temperature 

Applying a roof coating on your RV will act as a preventative barrier that will regulate the temperature inside the vehicle. This will keep the temperature inside your vehicle cool during the summer. 

Similarly, due to temperature regulation inside your motor home, you will use less power because you won’t have to keep your air conditioner on full blast. 

How Do I Reseal My RV Roof? 

Resealing your RV roof depends on the type of material your roof is made out of. Here are a few ways to reseal your RV roof, depending on the material. 

Start with Cleaning the Roof

The first thing you need to do before resealing is to clean the roof thoroughly to get rid of any dust and debris. 

Make sure to scrape off any old roof material and dirt particles. Be careful while you do this to avoid extending the tear or crack. Once you are done cleaning, dry your roof off so you can start the resealing process

Roof Type: Rubber RV Roof 

A rubber roof is usually more delicate than other materials, so it needs regular maintenance. However, even though rubber roofs are delicate, they tend to last longer than different types of RV roofs. 

The most common types of products to take care of your rubber roof are Dicor and EPDM coatings. Here are the steps you should follow:

  1. Inspect lap sealant: Observe the lap sealant and take care of any issues. 
  1. Clean: Remove any dust on the roof. 
  1. Cover appliances: Remember to remove vent fins and put on appliance covers. 
  1. Protect sealant: Tape the plastics to one side of your RV to protect it from the sealant. 
  1. Use a rubber coat: Apply a smaller brush to apply a rubber coat and the sealing on the fixtures. 
  1. Apply sealant: Use a normal-sized brush to apply the same coat and sealant on the top of your RV. 
  1. Apply coat: Apply two coats if your RV is old. 

Roof Type: Fiberglass RV Roof 

To restore the glossy outlook of your fiberglass, you’ll have to clean it thoroughly. Grab a sponge and some warm water to clean the roof and once you are done, let the top dry completely. 

For best results, make sure the surface of your roof is grease or oil-free. Silicone sealant works best for fiberglass roofs. Here are the steps you should follow to reseal a fiberglass RV roof:

  1. Inspect your roof: Start by inspecting your RV roof to understand the quality of the fiberglass. 
  1. Use a sealant: Get a sealant and match it with your fiberglass roof, preferably find a silicone sealant for the best results. 
  1. Apply a gel coat: Fiberglass is usually designed with a gel coat which is why it has a glossy texture. Consider applying a gel coat in the end, to keep your fiberglass in good condition for a longer time. 

Roof Type: Aluminium RV Roof

Aluminum RV roofs and household roofs are pretty similar due to the material. So, household roof coatings can do just as well as sealing cracks or holes. 

The best product to use for aluminum roof sealing is the Eternabond seam tape. It’s almost identical to duct tape, but it is much more handy and perfect for repairs. Here are the steps you should follow to reseal your aluminum roof:

  1. Clean the surface: Start by cleaning the roof’s surface. Make sure you start with a clean surface that is grease free. Plus, avoid using products that contain petroleum, as they can cause damage to your roof.
  1. Use coating: You can use a special Dicor metal RV coating so that the top layer of your roof is dust and rust-resistant.
  1. Seal it in: Seal all the joints or rivets using a caulking gun. 

How Much Does Resealing Your RV Roof Cost? 

Resealing your roof is one of the best decisions you can take for your motorhome. Doing this will not only help maintain the vehicle, but it will also maintain the integrity and strength of your RV’s roof. 

But how much does it cost to reseal your RV roof? The cost of resealing your RV roof depends on several factors, such as material, handyman, and size. For starters, you need to consider whether you will get a handyperson to do it for you. 

Hiring a professional to fix the roof for you will cost more but will ensure your job is done correctly. 

Usually, resealing your RV’s roof yourself may cost around $250-$600, while having it professionally fixed will cost anything between $800-$1000. Additionally, if you own a larger RV, sealing your roof may cost around $1500-$2000 at least. 

However, it is equally important to remember that these prices vary according to your roof’s size and material. 


You have probably heard the saying, “nothing lasts forever,” and that applies to RVs as well. RV Roof maintenance is an essential part of maintaining your motor home. 

Although modern roofing materials are exceptional and can last several years, sun damage and weather conditions can eventually cause wear and tear. 

Inspecting your roof regularly for any signs of damage or wear and tear that may require immediate attention is also important. By taking care of your RV roof with regular sealing and maintenance, you’ll ensure it stays in good condition for many years of adventure!
