How Often Should You Seal Your RV Roof?

RVs require various types of maintenance, but one of the most important things you can do to protect your investment is to regularly seal your RV roof.

Depending on the type of roof your RV has, you may need to seal it as often as every six months or as little as once a year. If you live in an area with severe weather conditions, such as high winds and hail, you may need to seal your RV roof more often.

If you don’t live in an area with severe weather conditions, you can probably get away with sealing your RV roof once every year or two.

How Often Should You Seal Your RV Roof?

RV roofing is prone to leaks, so it’s a good idea to seal your roof occasionally to protect your RV from water damage. But how often should you reseal your RV roof, and what are the best products to use?

Sealing your RV roof is important to protect against leaks, but you don’t want to overdo it. Most experts recommend sealing your RV roof every 1-2 years, depending on the type of roof and the severity of weather conditions in your area.

Even if there are currently no rips, cracks, or holes in your roof, the sealant will eventually degrade and need to be replaced. If you live in an area with harsh weather conditions (high winds, hail, etc.), you may need to seal your roof more often.

Signs That You Need To Reseal Your Campers Roof

It’s a good idea to reseal your RV roof whether there’s anything wrong with it or not, but there are some situations that will require you to reseal your roof more often.

Here are a few signs that you need to reseal your roof:

1. Your Roof Is Leaking

If you notice water damage on the ceiling or water coming in through the walls, it could be a sign that your roof is leaking, which means it needs to be repaired and resealed immediately. Inspect your roof to find the source of the leak and make the necessary repairs before applying sealant.

Roof leaks can be caused by rips, cracks, or holes in the roof, so make sure to inspect the entire surface for any damage. If you’re not sure how to fix a roof leak, contact a professional RV roofing contractor for help.

2. The Sealant Is Wearing Away

If you can see that the sealant around your roof is wearing away or peeling off, it’s time to reapply. This usually happens every 1-2 years, but if you live in an area with harsh weather conditions, you may need to reseal more often.

You can identify worn sealant by its color; it will usually turn from white to brown or black. If the sealant is cracked, peeling, or missing in spots, it needs to be replaced.

3. Your Roof Is Damaged

If your roof has been damaged by a storm or other event, it’s important to have it repaired and resealed as soon as possible to prevent further damage.

Even if the damage doesn’t seem severe or your roof doesn’t seem to be leaking yet, it’s always better to err on the side of caution and repair the damage before something worse happens.

Once the damage is repaired, you can apply a new layer of sealant to protect it and ensure that it won’t leak. It will also protect the spot that was previously damaged since after the damage is repaired, this part of your roof will be weaker than it was before.

4. It’s Been More Than 1-2 Years

Even if there’s no visible damage to your roof, it’s still a good idea to reseal every 1-2 years to ensure that it stays watertight. The sealant will eventually degrade over time, so it’s important to reapply it regularly to prevent leaks.

The older your roofing, the easier it is to damage it. A new roof may require severe weather to damage it while an older roof may rip in just a light breeze. Resealing it as it ages strengthens the roof and helps prevent unforeseen disasters.

Benefits Of Resealing Your RV Roof

Aside from preventing leaks, there are many other benefits to resealing your RV roof, which is why you should be diligent to do it regularly.

1. It Strengthens The Roof

Sealing your roof helps to strengthen it and prevent future damage. The sealant forms a barrier that protects the roof from the elements and keeps it from drying out and becoming brittle.

Many people think the only reason to seal a roof is to prevent leaks, and while that’s a great reason, it also helps to reinforce the roofing and keep it stable.

2. It’s Inexpensive

Sealing a roof is much cheaper than replacing it, which is why it’s important to do it regularly.

A new roof can cost thousands of dollars while enough sealant to cover the roof is only a few hundred dollars. By resealing your roof every 1-2 years, you can save yourself a lot of money in the long run.

3. It’s Easy To Do

Many people think that sealing a roof is a difficult and time-consuming task, but it’s actually quite easy to do.

You can either do it yourself or hire a professional RV roofing contractor to do it for you. Either way, it’s a quick and easy process that doesn’t take very long.

4. It Prevents Leaks

The most important reason to reseal your roof is to prevent leaks. A leaking roof can cause serious damage to your RV, so it’s important to make sure that it’s well-sealed at all times.

By resealing every 1-2 years, you can prevent leaks and keep your RV in good condition.

5. It Increases Energy Efficiency

Sealing your roof also helps to increase energy efficiency since it prevents heat from escaping. In the winter, this can help to keep your RV warm, and in the summer, it can help to keep it cool.

Either way, it will save you money on your energy bills.

Can I Walk On My RV Roof? Is It Safe?

is it safe to walk on an RV roof

Walking on your RV roof is safe, but you should only walk on it if it’s absolutely necessary. Take precautions to prevent damaging it, because walking on it can cause leaks and other damage.

If you do need to walk on your roof, make sure that you’re using the proper footwear. Avoid walking on it in high heels or other shoes that could puncture the roof. Instead, wear rubber-soled shoes or boots to provide a good grip and prevent slipping.

When walking on your roof, be sure to avoid walking on any vents, skylights, or other delicate parts of the roof. Also, avoid walking on or near the edges of the roof since this could cause you to fall and seriously hurt yourself.

If possible, have someone else hold onto you while you’re walking on the roof to prevent accidents. And, be sure to inspect the roof before walking on it to make sure there’s no damage that could cause you to fall through.

In general, it’s best to avoid walking on your roof if possible. However, if you do need to walk on it, take precautions and be careful to prevent damaging it or injuring yourself.

Best Sealant To Use For Your Motorhome Roof

The best sealant to use for your motorhome roof will depend on the type of roof you have. For example, if you have a rubber roof, you’ll need to use a different sealant than if you have a fiberglass or metal roof.

If you’re not sure what kind of roof you have, check with the manufacturer or a professional to find out. Once you know what kind of roof you have, you can choose the right sealant for it.

For rubber roofs, use a sealant designed specifically for that type of roof, like EternaBond. For fiberglass or metal roofs, you can use a general-purpose sealant like silicone or butyl rubber. These aren’t quite as expensive.

Whatever type of roof you have, be sure to choose a high-quality sealant to ensure that it will last. Also, follow the instructions on the sealant can to ensure you’re using it correctly.

There are also many different types of sealants available, so be sure to read the labels carefully to find one that’s compatible with your roof. In general, look for a sealant that’s specifically designed for RVs, since it will be formulated to withstand the harsh conditions that RV roofs are exposed to.

When choosing a sealant, you’ll also need to decide what kind of application you want. Some sealants come in aerosol cans, while others come in tubes that fit into a caulk gun. There are also self-leveling sealants that spread evenly on their own.

Decide what type of application you want, keeping in mind that some applications are easier than others. For example, self-leveling sealants are very easy to apply, but they can be more expensive. Caulk guns are less expensive but can be more difficult to use.

In general, you can expect to spend between $100 and $300 to reseal a camper roof.

Is it OK to Caulk Over Old Caulk?

When it comes to caulk on an RV roof, the short answer is: no, it’s not a good idea to caulk over old caulk. Caulking is only effective when applied directly to a clean surface, and layers of old caulk can prevent that seal from forming properly. If you do need to repair your RV roof, it’s important to remove any existing caulk before applying a new layer.

Caulking is one of the most important tasks in keeping an RV in good condition and helping it to last for many years. If you don’t properly remove old caulk, water can get underneath and cause damage to the roof and other parts of the RV. This can lead to costly repairs down the line, so it’s important to do the job correctly.

RV Roof Maintenance Tips

If you want to caulk over old caulk on an RV roof, here are a few tips:

  • Use a caulk remover or solvent to break down and remove any existing layers.
  • Use a scraper to scrape away any remaining residue before cleaning the surface with a degreasing agent.
  • Apply the new caulk in thin layers and be sure it is evenly spread across the entire area you want to seal.
  • Allow the caulk to dry completely before walking on the roof and exposing it to any elements.

By following these steps, you can help ensure that your RV roof is properly sealed and protected from leaks, moisture, and other damage.

Proper maintenance of your RV’s roof is essential for keeping it in good condition.

Caulking an RV roof can be a tricky job, especially if you’re not familiar with the process. If you’re unsure of how to do it, it’s best to hire a professional to handle the job for you.

But with proper preparation and care, you can caulk over old caulk on an RV roof and keep your RV watertight for years to come.


Sealing your RV roof is an important part of maintaining it and keeping it in good condition. Be sure to choose the right sealant for your roof and follow the instructions carefully to ensure that you’re doing it correctly.

If you have any questions, be sure to consult with a professional before beginning the job. With a little care and attention, you can keep your RV roof in good condition for many years to come.
