A rubber roof membrane is an essential part of any successful rubber roofing job. However, if you want to change the style of your roof, youll have to remove the rubber roof membrane. This can be achieved rather easily and without much expense on your part. You will only need a few readily available tools.

One thing to consider before performing the tear-off is the way that the roof was initially installed. The following procedure will guide you through the tear-off of a roof that was applied with liquid or latex adhesive. If your rubber roof was nailed down you will need to have a hammer available to remove nails. If staples were used, you will have to be able to remove them as well. Dont worry, however, rubber roofing is the easiest to remove and doesnt require a professional.

Step 1Check the Weather

It is easiest to remove the rubber membrane when the rubber is warm. When the rubber is cold it can become rigid and stiff. If it is at all possible you should wait for warm weather to remove the membrane. Check the forecast to determine the best time to begin the project.

Step 2Cut the Rubber Membrane

Step 3Remove the Membrane

Can You Pressure Wash An Rv Roof

Stubborn stains and mold seem like they would quickly fly off the RV roof with a pressure washer. Though not highly recommended, it is possible to use a pressure washer but with caution. You will want to make sure that there are no tears or cracks or any other issues on the roof. The last thing you need is a leaky roof or water penetration anywhere on your RV. Also, avoid the sides of your rig as you dont want to damage the paint or any seals.

RV Roof Sealant

Monday 17th of August 2020

When you are driving your RV you dont know how much abuse it takes while on the road. Things like tree sap, harsh weather conditions, debris all are taking the life out of your motorhome. Therefore it is important to perform regular roof inspections to keep an eye on what is happening on the roof and taking corrective action as soon as possible. Cleaning the RV roof from time to time is a must to-do task. Leaks are hard to track for an un-trained eye and would not be visible without cleaning. Make sure whatever you intend to use for cleaning or re-coating is safe and compatible to use on your RVs roof.

What To Use For Rv Rubber Roof Repair

How to Clean Mold from RV Rubber Roof?

RV Roof Patch Kit

I recommend always having something on hand thats made for RV rubber roof repair. Whether its an RV roof patch kit or sealant tape.

If you dont have either of those things even some RV sealant could be used as a temporary fix. But you should replace it with a proper RV roof patch later.

Many full-time RVers, including me, recommend EternaBond Roof Seal Tape for RV rubber roof repairs and even resealing, which Ill talk more about later.

EternaBond repair tape has been around for a while. Many RVers have put this stuff to the test and the feedback has been super positive. Ive used it myself and my camper roof hasnt had any leaks yet.

Using whats called MicroSealant EternaBond can adhere to pretty much any surface, that includes TPO and EPDM rubber RV roofs.

Its super durable as well, the company claims it can last 18-35 years. So far that seems to be true.

Cleaner and/or Primer

The prep is the most important part of any camper repair. If its not cleaned right, nothing will work as it should.

Eternabond makes a EternaClean Spray Cleaner and an EternaPrime Adhesive . They are great options to have if you want to use them but they arent required.

I use dish soap and 91% isopropyl alcohol because thats usually what I have on hand.


If you are just patching over a small hole you wont need a roller but if its a long scratch or cracked seam you are going to want one.

Types Of Rubber Rv Roofs

Rubber RV roofs are either going to be made of ethylene propylene diene monomer or thermoplastic olefin . EPDM roofs are more durable than TPO roofs and require less maintenance over their lifetimes.

You may have to repair minor issues with TPO roofs more frequently, and TPO also needs to be resealed periodically. EPDM on the other hand does not require any kind of sealant or treatment, though you can often find manufacturer recommendations on how to clean and treat RV rubber roofs in your user manual.

Apply A Moisture And/or Microbial Barrier

Roofing materials and technology has advanced greatly within the last few decades.

One of those advances is the ability to apply chemicals to your existing roof that repels water, or prevents algae and mold from developing. New roofs are often constructed of materials that have these properties impregnated into them.

Materials Needed For An Rv Roof Repair

You only need a few items to repair your camper roof.

As you can see, you dont need to purchase many materials and they are relatively inexpensive. We had everything on hand already except for the Dicor Lap Sealant and the Eternabond tape which cost us less than $45 total.

Much cheaper than taking our RV to the shop for repairs or even an RV roof replacement!

How To Treat Rv Roof After Cleaning

How To Clean The Rubber Roof On a RV – What Should You Use

Treating your RV roof after cleaning is one of the most significant determinants of residue buildup. RV Roof Treatments protect against the sun and prevent oxidation. They also contain chemicals that resist contaminants like droppings from trees and animals, as well as dirt and grime.

Purchase EDPM and TPO safe protectants either online or at your local RV supply store. Inquire about products that are free of corrosive chemicals to prevent any mistakes.

Apply the roof treatment just after cleaning your RV roof. You will need about 16 to 20 ounces to cover the entire area. Spray in 3-foot by 3-foot sections and spread with a clean, damp sponge mop. Continue this process until you coat the whole roof. It needs 24 hours to air dry completely.

RV rubber roofs are generally made of either Ethylene Propylene Diene Monomer or Thermal Polyolefin . EPDM is the preferred choice of most RV manufacturers. Rubber roofs have a life of about 20 years, but they require frequent cleaning and repair. It is suggested that in order for your rubber roof to last long and to retain your warranty, you should clean your RV rubber roof at least once in every three months.

Cleaning the roof regularly is also the easiest way to maintain the roof. An EPDM roof has its own cleaning shortcomings as it has less solvent and oil resistance. Most manufacturers do have a warning that harsh, abrasive cleaners should not be used on EPDM roofs.

Why Your Rv Roof Is Turning Black

Today, most RV roofs are made of rubber, though you can find options with aluminum and fiberglass roofs. If youre traveling on the road with your RV, youve probably experienced weather that is less than perfect. If your RV has been exposed to water, such as rain or melting snow, theres a good chance some water has seeped into your roofs seams.

When the water seeps into the roof seams, there are two risks you should be aware of. One is that it will damage the inside of your vehicle, including the wall panels and the framework. The other is the risk of mold and mildew.

Mold and mildew grow quickly in damp conditions, such as those caused by waterlogged seams. Even if the water doesnt get into your RV, it can still cause issues with your roof.

The other reason that your RV roof may turn black is due to air pollution. This cause is substantially less common, though it is possible. When this happens, it is because the rubber in your roof reacts with the industrial gases in the air and slowly turns black.

You should clean your roof as soon as you notice any black spots. If you leave them as they are for long, theres a good chance the cause of the color change will bond to the roof surface, making it almost impossible to clean completely.

COMer said:I attended an RV seminar today, near Cleveland, and the factory rep from Dometic was there along with another fellow who claimed he was an expect on chemicals and additives for RVers. The Dometic guy said he had just attended a conference where industry reps were discussing the value of a protectant on a rubber roof after cleaning. They said that they determined there was no value at all but that because customers didn’t believe them, they continued to produce and sell a product. But the industry determination was that there was no need or benefit to a protectant.


WFD said:Very interesting! And makes you wonder how many other RV products are being sold and are totally not necessary.

One other thing they said. If you get mold, or mildew or black stuff on the rubber roof, clean it with hydrogen peroxide. They shuddered at somebody’s mention they used bleach and told of stories about bleach ruining a rubber roof. Use peroxide.

carson said:Another recommendation: Mix a cup off OXYCLEAN laundry powder in a 5 gallon pail of lukewarm water and use as if it werer Bleach. Oxyclean contains Peroxide and works like a charm to kill Mold and Algae and is non-toxic to skin and plants. I used it to clean my Pool screens that where heavily invaded by a thick layer of Algae and mold.

Clean The Rubber In Sections

To ensure safety, always clean your RV front to back. This way, you can climb off the ladder without stepping over the wet, slippery surface. Using a spray bottle, cover a 3-foot by 3-foot area. Then, use your brush of choice to clean in a circular motion. Apply moderate pressure, but not too much, as you do not want to hurt the rubber. Rinse off the dirt in the bucket and continue mopping.

Tip #4 Use Water And Dishwashing Detergent Solution

It is also possible for you to clean up the rubber roof of your RV with the mixture of water and dishwashing detergent. You just need to apply the mixture using a medium-bristle brush as a means of removing the molds and stains.

However, ensure that you avoid using a dishwashing detergent or cleaner, which contains citrus ingredients, harsh abrasives, and petroleum solvents. These ingredients might damage the rubber severely.

In case this solution is still incapable of removing stubborn mildew, molds, and stains, you can use a cleaner specifically designed for rubber roofs as an alternative.

Materials Youll Need To Repair A Fiberglass Rv Roof

If you want to restore the gloss of your fiberglass RV roof, youll first need to clean it thoroughly. You can use warm water with a sponge for cleaning and then allow it to dry for some time. If you want to achieve the best results, the surface of your fiberglass RV roof needs to be free from any grease or oil.

Silicone sealants work best. I also recommend placing a gel coat over it once youre done.

Patching A Large Area On A Rubber Rv Roof

Cleaning a Very Dirty RV Rubber Roof Membrane

Clean the damaged area with soapy water and allow to dry. Determine if you have a rubber roof. Repair of metal and fiberglass roofing is handled in the next section.

Apply splice cleaning solution to the damaged area and allow to dry.

Measure the damaged area and cut a piece of rubber roof membrane large enough to extend 3 inches past the area in all directions.

Apply a base coating of rubber roof adhesive to the damaged area, extending 3 inches past the damage in all directions. Allow to dry.

Apply a second coat of roof adhesive to the damaged area, covering the first coat completely. Apply a coat of adhesive to the membrane patch.

Place a patch over the damaged area. Go slow and smooth out the membrane as you apply the patch. Once contact is made between the membrane and roof, the membrane cannot be moved.

Repeat Steps 1 through 6 for very large repairs, overlapping the membrane material by 3 inches. Seal all seams and edges with lap sealant to complete the repair. Allow to sit for at least two hours before driving the RV.

Can I Pressure Wash My Rv Roof

Pressure washing is not recommended for motorhomes and trailers, because it can damage the fiberglass, as well as the decals. Likewise, pressure washing can damage the seals and caulking around your RV windows. In fact, some RV rubber roof cleaning products recommend power washing the roof before you recoat it.

What To Know Before Buying Rv Roof Cleaner

Choosing the right RV roof cleaner boils down to the factors you consider while shopping. Purchasing based on gut feelings or emotions without taking into account the necessary elements may only lead you to experience a condition called buyers remorse.

Avoid the regret of purchasing the wrong product. Continue reading to know some of the essential factors you need to consider when buying a roof cleaner for recreational vehicles.

The quantity of the roof cleaner you buy should coincide with your camper. Keep in mind that a 32 oz. bottle might not provide enough coverage for a 40-ft. trailer. Also, buying a gallon of roof cleaner might not be the most economical choice if you are a proud owner of a reasonably small camper.

In short, consider the size of your vehicle. Then, use the measurement to help guide you in purchasing the right amount of RV roof cleaner you need.

  • Convenience

Some roof-cleaning solutions may require more than one use to effectively remove dust, dirt, mold, and grime. But, some variants may only require one application to eliminate these filthy substances.

It should be part of your shopping list to purchase a cleaner that will not take up most of your weekend afternoon removing unclean elements from your RVs roof. One way to ensure that you are going to purchase a potent cleaning agent is to read online reviews.
