The article below will go over the top kinds of RV roof material and the costs associated with them in addition to describing the steps needed to seal repair, replace, or repair the camper’s roof. I’ll also give tips to ensure that the RV roof in top state of repair.

Type Of RV Roofing Material And How Much Do They Cost To Replace

The most commonly used kinds of camping roofing material include TPO, EPDM, fiberglass and aluminum.

The majority of the time, EPDM and TPO are the most widely used and most common kinds of material employed for RV roofs.

Every type of roofing material offers different benefits as well as costs and maintenance requirements. Let’s look at it!

Rubber EPDM (Ethylene Propylene Diene Monomer) is synthetic rubber material with a membrane-like design which is commonly used for flat roofs, such as those found on travel trailers and RVs.

EPDM can be extremely long-lasting and economical it typically costs between $4-$8 for a square foot.

Based on our 30 foot RV example, it will cost between $1,020 and $2,040 for an EPDM 255 square foot roofing material to cover the RV in the event that it is eight feet in width.


The TPO (Thermoplastic Polyolefin) is the most popular material that is used in RV roofs.

The material is one-ply, which means that it’s just a one-layer of rubber that has a the scrim for reinforcement. Similar to EPDM the material is used primarily to make flat roofing.

TPO is extremely UV-resistant and it will help to lower energy usage when used as an RV roof. Furthermore, it’s extremely long-lasting and, if maintained properly it could last up to 30 years.

Good quality TPO RV roofing is priced about $5.50 to $6 for each square foot. So, with our camper that is 30 feet, the cost of the TPO by itself would range between $1,400 to $1,530 for the 255 square feet of material.

However, if there are multiple areas where the roof is damaged, or there’s a single area with extensive damage that is compromising the rest of the roof, it may be time to replace it. 

Tools You Will Need

When you plan to repair or replace your camper’s roof yourself, there are some tools you’ll need to get the job done as quickly and effectively as possible.

Although every job is different, some general tools you should have on hand for dealing with your RV roof include:

  • Safety glasses
  • Roller to roll out and flow the adhesive
  • Acetone or other cleaner, like a 3M Scotch Bright Pad
  • Razor knife or shears for cutting the replacement material
  • Scraper or utility blade to remove old caulking
  • Respirator (for fiberglass roofs)
  • Rubber gloves
  • Bucket for mixing adhesive/catalyst

Prepare Your RV Roof For Repair Or Replacement

The first step to any RV roof job is to clean the existing roof or repair area well. In order for the adhesive or catalyst material to bond with the roof material, all traces of oil, grease, grime, oxidation and silicone sealants must be removed.

If it’s just a small repair, feel free to use a rag and a solvent to scrub the area clean.

For larger repairs and full roof resealing jobs or replacements, it might be more effective to first power-wash, then scrub where necessary until the roof is completely clean. 

With EPDM roofing, you will need to cut away any residual silicone caulking and remove any surface wax with a removing agent designed for this purpose.

Once the roof is dry after cleaning, you will likely need to apply an EPDM primer.

Even if you did a fantastic job cleaning the roof, it’s likely to still be dirty or stained in some areas, so using a EPDM primer will prepare the surface for a better bond between the roof and the tape.

  2. Remove any excess silicone. 
  3. Apply sealant or caulking to any recesses, and let dry. 
  4. Glue down any loose roof membrane, and add fasteners if needed. 
  5. Let it cure 24 hours. 
  6. Apply the patch so that there’s at least two inches of overlap on all sides of the repair area, and cover any reinforcement fasteners.
  7. Seal the patch and edges around it with RV roof coating.

RV roof tape or RV roof patches are easy to apply, with adhesive on one side that sticks to your RV roof and seals up the torn or punctured area.

These patches are very durable, and provide a permanent solution to a tear or small hole.

How to Replace Your RV Roof

A DIY RV roof replacement is certainly possible, and will help you save lots of money since you will only need to buy the materials.

The following are all of the steps to follow when replacing your RV’s roof:

  1. Remove any fixtures, such as vents, antennas, or air conditioning units. Remove the awning as well.
  2. Use a high-quality stainless steel putty knife to scrape away the old sealant around the removed fixtures.
  3. Remove the existing roof membrane. For RV’s rubber roofs such as TPO or EPDM, you will need to peel back the roofing material until you can see the plywood structure beneath. Aluminum roofs require you to unscrew the old panels to remove them, and you will need a dye grinder to remove the fiberglass matting that covers these types of roofs.
  4. Check the plywood beneath the roof membrane for damage. If you notice areas where the wood is rotted or bowing, it has water damage and should be replaced. Clean the rest of the (undamaged) plywood with mineral spirits to treat it to prevent mold and mildew from growing.
  5. Install seam tape in places where the plywood meets and along the edge of the camper’s roof where it meets the side of your camper. This will help maintain a good seal and reinforce any weak areas.
  6. Rubber roofs are installed by coating layers of adhesive onto the plywood roof, then rolling on the roof replacement panels. Fiberglass roofs have similar installation, and you will paint on the adhesive catalyst resin before covering it with the fiberglass matting and gel coat. Allow the adhesive to sit for a little bit until it’s tacky, and then roll your roofing material over the top, pressing out all air bubbles as you go. Cut holes in the rubber or matting for any fixtures that are going back on the roof.

The least common RV roofing material you’ll come across is aluminum. Certain travel trailers like Airstream make use of aluminum roofing but it is a much more weight than other camping roofing materials.

Similar to fiberglass, aluminum has low maintenance requirements, and unlike fiberglass and rubber it’s not toxic.

You can also reuse your old roofing as you replace it, as aluminum is one of the very few materials that don’t lose value.

Aluminum roofing sheets are priced at around 3 cents per square foot. So, the price to replace the roofing material on a 30 foot by 8 1/2-foot camper would be about $770.

Reinforce The Sealant

It’s suggested that you frequently examine your camping vehicle’s roof for leaks and to reinforce it with sealant on the edges at a minimum of once every year.

While doing this, be certain to seal your air cooling unit roof openings, skylights as well as other areas that could have the possibility of a crack or seam within the roofing material.

If you’ve never applied the sealant prior to now, test its compatibility by applying a small amount to an unnoticed area prior to applying it to all surfaces.

The coating is essential as it improves the waterproof and weatherproofing capabilities of the entire roof.

Keep your mind in the forefront that you may require a particular kind of coating in accordance with the kind of roof material you’re using.

Another method for recoating is to use an RV liquid roof that comprises an EPDM coating which can paint on your roof that covers your camping vehicle.

The liquid roof costs about 90 cents per gallon. This covers around 42 sq feet. For our 30 foot by 8 1/2 feet camper, we’d require around six gallons to completely cover the roof.

You could save money if you purchase the material in greater quantities, like five or four-gallon pails.

When dry when it is dry, the liquid roof shields the roof from ultraviolet rays of the sun. It also acts as weatherproofing to stop moisture from entering and slow wear and tear from the elements.

By regular coating you RV roof by applying this kind of protective sealant You can prolong the lifespan that you have of your RV and stop water damage from occurring.

So, frequent cleaning is essential to maintain the integrity of seals and the waterproofing on the camping roof.

A best practice is to clean the roof whenever you’re deep-cleaning following every camping trip.

To clean your RV roof correctly, select your detergent according to the kind of roof that you have.

If the RV’s roof is made of fiberglass or aluminum then you can wash it with a similar mild soap that you use to clean all the other parts of your RV.

2: Check For Leaks

The roof cleaning process is the ideal time to inspect the RV’s roof for any leaks.

When you’re power-washing the roof Ask your spouse or a close friend to go around in the cabin, looking over the walls and ceiling for drips or dampness.

When you clean or rinse the roof and look at cracks within the roof seal. Also, check for any soft spots that could be the sign of rot or water damage. Make repairs as quickly when you find them, to limit damage.

3. Repair RV Roof Damaged ASAP

If you spot the presence of leaks or any other damage on the roof or the fixtures on it and fixtures, fix them.

It’s better to invest just a few hundred dollars for repairs in the near future, rather than to shell out nearly $10,000 to replace the entire roof.

Furthermore, any damage that is allowed to go untreated can become worse and result in further issues, or even costly repairs that are more expensive and extensive.

It’s the same for roof-top systems, such as your air conditioner. If it ceases to function the system will be flooded with moisture within the system and stress sealing between it and your roof or cause mold and mildew to grow.

Therefore, it’s recommended to take your RV some time and only be sure to cover it during storage season.

Notice: Tarps are even more harmful than RV covers in permitting mold and mildew to spread over the short time therefore, only utilize them as a temporary solution.
