How You Should Handle Your Next RV Roof Repair Job

A lot goes into making an RV road-worthy and comfortable. While it takes all kinds of different parts, it should go without saying that the roof is essential. Even the tiniest of leaks could become a big problem if you don’t quickly repair it with EPDM.

EPDM Is Long Lasting

The only thing worse than having to handle RV roof repair because of a pesky leak would be going to the trouble of fixing the problem only to have it happen again. Too many RV owners have had to go through this. They think the problem is history. Then they hit the road. As soon as it rains again, they realize they were mistaken and are now too far away to do anything about it.

You can rest assured that EPDM will take care of the leak once and for all. Chances are you’ll never have to handle an RV leaks repair job in that area ever again.

Simple Application

If you pay someone to take care of your RV roof repair needs, it can be still be pretty affordable if they use EPDM. That’s because this form of RV rubber roof repair is so easy to apply there will be minimal labor costs to cover.

This means that it’s also easy to handle on your own. You can find all kinds of EPDM products these days. Most just require you to spray them over the problem area. Then just wait for it to dry and you’re good to go. Larger leaks may need a version that is applied more like paint, but it still won’t require much time and you definitely don’t need prior experience using it.

Affordable

Like we just touched on, EPDM is extremely affordable, even if someone else applies it for you. Depending on the size of your leak, you should be able to fix the problem and still have plenty of the rubber left over in case you ever need it again.

Little-to-No Maintenance

Just like you don’t want another leak springing up after you went to the trouble of fixing the first one, you also don’t want to spend hours of your life going forward making sure that your repairs will stick.

Fortunately, EPDM is extremely low maintenance. In fact, cleaning the area is basically all it takes to keep any recurring problems from being an issue. It doesn’t take much, though, so just hit the area like you normally would when you wash your RV and you should be fine.

Preempting Problems

If you want to make sure that needing an RV leaks repair job never becomes necessary, your best bet would be to use EPDM beforehand. Again, it’s extremely affordable, so you won’t have to break the bank to cover the roof of your RV with the material. This coating won’t just keep the rain out, though. It will also keep the sun’s rays at bay and your A/C inside where it belongs.

RV rubber roof repair is the way to go when you get a leak. Just be sure it’s EPDM and that you handle the job right away.

Roof Leaks Are No Match for EPDM

No one likes a leaky roof. With each drip, the problem becomes more and more annoying. Of course, if you’re only experiencing the problem a drip at a time, you’re in luck. Far worse is a roof leak you don’t know about until it compromises a circuit or starts showing up on your walls. Water can cause a lot of damage, especially when it’s given plenty of time to work. This is why you want to handle your leaking RV roof repair ASAP. However, it’s also why you absolutely must pick the right solution for the job, which usually means EPDM.

EPDM Is Quick and Simple

Depending on your abilities, you may be able to fix roof leaks all by yourself with EPDM. For smaller jobs like leaking roof repair, it’s usually applied in liquid form. You can just spray it over the spot in need of repairs (after it’s been cleaned, of course) and let it dry. Your roof won’t be having any more issues in the future.
Even if you need to hire someone for the job, you’ll be in for a quick turnaround. Unlike having to remove shingles or panels, EPDM roofs don’t need much more than a cleaning before more is applied. In some cases—say, if you own an RV—your current roof may not be made from ethylene propylene diene monomer, but the substance can still be used for a quick repair.

You’ll Save Money

Hiring someone to fix your roof is notorious for being expensive. As you can probably guess from the above, though, having someone use EPDM won’t cost you much. The labor shouldn’t last for more than an hour and the rubber is well-known for how inexpensive it is. You shouldn’t have to worry that saving your home (and sanity) is going to break your budget.

Get a Tight Seal

While EPDM is known for being cheap and many other flattering features, the real reason it gets used so often to repair roof leaks is because everyone knows that the seal it forms can’t be beat (at least not without spending a lot more on the process).
If you live in a climate where the rain can be vicious, you’ll be glad you have EPDM covering up the vulnerable spot on your roof. The same goes for those of you who live in areas where you often need to repair roof leaks because of the punishment provided by snow.
EPDM isn’t just some temporary solution either. Once you apply it, that rubber will be there for decades. Temperatures ranging from negative 40 all the way up to 300 Fahrenheit have proven to be no match for the tight seal made by EPDM.
While EPDM is the answer to your prayers when you need to fix roof leaks, it’s also worth considering what this rubber could do as a larger application. EPDM roofs are extremely popular for commercial buildings and RVs, but there are also a number of residential applications you could benefit from too.

Understanding Roof Sealants

One of the most popular choices in roof coatings are actually roof sealants. These materials are designed to address specific needs, including the type of roof, the conditions to which they are subjected, and they can provide weatherproofing and reflectivity. Knowing what kinds of roof coatings are available is an important part of determining which option will work best for your situation. The following are some of the most widely used roof sealants.

Urethane Sealants

Roof coating manufacturers have been creating polyurethane-based sealants since the early 1960s, and they have certainly come a long way since that time. These sealants are available in systems that use one and two part moisture-cure and oxygen-cure processes. These roof coatings are most popular for use with EPDM membranes, especially in areas around flashing, coping, pitch pans, and termination bars, as they provide a water resistant seal. Urethane sealants range in price, but the lower end options tend to have very poor resistance to UV exposure. Additionally, they cannot stand up to anything other than very minimal dampness at the time of application, as the added moisture results in outgassing. When this occurs, the expansion and frothing that occurs results in extensive damage to the coating.

Silicone Sealants

Silicone is another popular option for roof coatings, and there is a wide range of formulations. There are acetoxy-cure formulations, which are generally the cheapest, and the more expensive oxime-cure formulations. Acetoxy roof sealants can’t be used on metal surfaces due to corrosion, but they do resist discoloring due to UV exposure. Oxime-cure silicones work well with metals, provide better adhesion, and resist weather, but they do tend to discolor after UV exposure. These roof coatings are not a good option for areas that have substrates that release heat and oil, as this tends to loosen adhesion.

Polysulfide Roof Sealants

Polysulfide sealants have a long history of use, and they are elastomeric in nature. They tend to be more expensive than other options, but they provide excellent resistance to weather exposure, allowing for a long life of around 20 years before cracking occurs. This sealant will generally need to be applied over primed surfaces, and it has longer curing periods.

Polyether Sealants

Polyether roof coatings are moisture-cure, and provide increased durability over some of the other roof sealants available. These sealants have a good rate of adhesion, and can be applied in colder temperatures without compromising the material. They provide good weather resistance, are environmentally friendly, and are highly OSHA complaint. They are easy to apply, fast curing, and typically last for 20 to 30 years when applied properly.

When it comes to choosing the right roof coating manufacturer, your best option is to make sure to compare products. Some of these sealants are better for certain jobs than others are, and making sure to understand the best applications will improve the life of whichever roof coating you choose. By paying close attention to the choices, you will be able to choose the material that best meets your needs.

The Proper Methods for Repair with EPDM Coating

EPDM, which stands for ethylene propylene diene monomer, has a proven history of providing exceptional life after application in all climates. However, there are times when the material might become damaged. In most cases, this damage occurs due to a seam lifting. This can be due to improper application due to the installer failing to use enough adhesive, or because the membrane was not cleaned properly. Whether the repair is needed due to damage or a seam, the following steps will help you make the proper repair with EPDM coating.

Plan It Out

You will want to plan your repair ahead of time to make sure the weather is going to provide the best conditions. The EPDM will require temperatures of around 55 degrees to cure properly. You will also want to complete the repair with EPDM coating when it is not scheduled to rain. While it will be waterproof right after it is applied, rain can make it appear spotted if it hasn’t had time to cure. It will usually take around nine days for the EPDM to fully cure, or considerably longer if it is applied during cold weather.

Get the Surface Ready

You will need to double check the roof to make sure you have all the areas that need repaired ready. They should have any holes or gaps filled in with a non-silicone caulk. Once those areas are filled in, the area will need to be cleaned thoroughly. A pressure washer works best, but if that isn’t available, you’ll want to make sure you remove all traces of dirt and debris. After that, clean the area with a mild soap and water, or something stronger if there is any mold, mildew, or fungi growing. Once the roof is completely dry, you will be ready to repair with EPDM coating.

Application

You will need to mix the catalyst following the directions provided with your product. You will need a nap roller to ensure an even coating. If there are any areas in which the roller won’t fit, you can go back after the rolling is complete and use a paintbrush to touch up any of those areas. Your goal is to apply a single coat that is around 20 mil thick, which generally equals one gallon to around 40 square feet on a smooth surface. If you are unsure of the proper thickness, take the time to measure off the 40 feet (or 30 if you are working with unsmooth areas), as you want to make sure you have the right thickness. If it’s too thin, it might crack, and too thick will lead to bubbling or excessive swelling.

Make sure to cover the entire surface completely and evenly at the recommended thickness to ensure a proper repair with EPDM. Due to the nap of the roller, it will look slightly bumpy, but the liquid is self-leveling, so this will go away as it cures. If you followed these steps, your application will just need to cure, and the process will be complete.

Liquid Rubber EPDM Roof Coating Application

When it comes to rubber roofing, there are few that can compare to EPDM membranes, except, of course, the liquid rubber form. This roof coating provides all the properties you expect from the traditional roofing membrane, yet is in a liquid form that provides numerous benefits. If you are looking for a roofing option that will protect against leaks and withstand any kind of weather you can throw at it, EPDM liquid roof repair is the best option. However, it is important that you understand a few things about the application process to ensure the superior results you are looking for.

Understanding the High Solids EPDM Rubber

EPDM liquid rubber uses a cure mechanism that converts it from the liquid form at application to a solid elastomer. It is designed to withstand both cryogenic temperatures and extreme steam heat, all without breaking down. Liquid rubber EPDM requires only a single coat, making it a cost effective, timesaving solution over other liquid roof coatings.

Primer

In most cases, the liquid rubber application does not require a primer, which further lowers costs and time. The following are some of the substrates that do not need to be primed prior to application:

  • EPDM Membrane
  • Weathered Fiberglass and Steel Siding
  • Weathered Corrugated Metal and Standing Seam Roofs
  • Weathered Polycarbonate Plastic, Vinyl, and PVC
  • Foam Pipe Insulation
  • Cast Concrete

While this product can be applied as an airless spray in some situations, when working with flat roofs, it requires a roller and a squeegee to get the job done.

A Note on Mixing

When mixing the catalyst into the liquid, you need to ensure that you follow all mixing directions exactly to ensure the best cure after the liquid rubber application. Trying to cut down the mixing time will not make the process any faster, and will only result in a subpar application.

Rubber Membrane Application

Liquid rubber EPDM coating can be applied over the EPDM membrane with only a thorough cleaning in most cases. However, if the membrane is older, it is very large, or cleaning is not quite practical, a liquid rubber surface conditioner is recommended to ensure proper adhesion.
