Buyer’s Guide to Buying the Best RV Roof Cleaners

If you’ve not yet decided which product to go for, take a look through our handy RV roof cleaner buyer’s guide. Here’s all you need to know to find the best RV roof cleaner for your motorhome.

Price

You’ll find many RV roof cleaners at a range of different prices.

While you may be tempted to opt for the cheapest product, you could in fact save yourself time and money by opting for a more expensive all-in-one product, rather than a separate cleaner and protectant.

Aside from considering what extra benefits your formula may provide, you should also consider the format when deciding on a price. If you are comparing a spray bottle with a concentrated product, for example, while the spray-on could be cheaper, the concentrated format is likely to last you much longer and often provides better value for money.

Finally, if you’ve not yet settled on a brand or specific type of RV roof cleaner, we recommend trying out a smaller version first. While this will cost you a little more first time round, you won’t be stuck with a large amount of product that is unsuitable for your rig or not effective enough for your roof condition.

Also if it’s a spray version, you can often later purchase larger, more economically priced refill formats to top up.

Roof Type

Always double check that your roof cleaner is suitable for your RV roof before buying. It sounds obvious, but as RV roofs can vary considerably, you really need to make sure that your cleaning product is intended for your specific roof type.

EPDM rubber or TPO roofs can be damaged by cleaners containing petroleum causing them to crack and lose their durability. Using an unsuitable type of cleaner for this type of roof will quickly reduce its lifespan, leading to some costly repairs, especially if your RV is parked up over winter and you’re unaware you’ve got a leak.

Likewise, for fiberglass RV roofs, certain chemical compounds can damage your roof’s protective coating. If you’re not sure, drop the manufacturer or the seller a quick inquiry to find out more. Otherwise, stick to products that clearly mention their suitability with your roof type.

Roof Size

If you drive a big rig, obviously you’re going to need a lot more roof cleaner than someone who tows a teardrop trailer. However, once you find a really good roof cleaner, there’s no reason not to invest in a large bottle that will suffice for a year or longer.

For large class As and fifth wheels, you’ll want to select a large format, preferably one that you can dilute. That way you should have enough for one intensive clean or two standard washes. For small trailers, you may want to opt for smaller spray on versions, however, it can be useful to have a larger quantity on hand for future use and those unexpected occasions where you unexpectedly end up needing to clean your roof.

Is it Biodegradable?

Before purchasing an RV roof cleaner, check that it is biodegradable. As your RV roof cleaner may end up in waterways, rivers and oceans, it makes sense to ensure that it will break down quickly to minimize any negative impact upon nature.

RV Roof Cleaner Types & Formats

RV roof cleaners tend to come in three main types: spray-on, concentrate and rinse-free. Here are some of the reasons you may want to opt for or avoid each type of RV roof cleaner.

RV Roof Spray Cleaners

  • Practical – simply spray on, no need to mess about with buckets and mixing.
  • Ideal for small surfaces, or targeting stubborn stains over small areas.
  • Less suitable for very large roof surfaces.
  • Use less product – save money and better for the environment.
  • Smaller quantity – often less value for money, but ideal to try out.

Concentrated RV Roof Cleaners

  • Tend to offer better value for money as they work out cheaper per gallon once mixed up.
  • Use less packaging.
  • Good choice for large RV roof surfaces – you can go over again without worrying about running out halfway through.
  • Excellent for tough stains – use neat to spot treat.
  • Bulky and heavy to transport – decant into a smaller container for on-board storage.

Rinse-free RV Roof Cleaner

  • Save time rinsing your roof after cleaning.
  • Use less water and have less product dispersing into waterways – more environmentally friendly.
  • If your RV roof is very dirty, then you may need to rinse off the dirt regardless.
  • Best for RV roofs in good condition.

Why Do You Need An RV Roof Cleaner?

RV roofs need regular cleaning to avoid costly degradation and maintenance. If you don’t look after your RV roof then sooner or later, it will need repairing.

Using a specialist RV roof cleaner is the best way to ensure that cleaning your roof is going to protect and condition it rather than inadvertently damaging it further.

Here’s why you need an RV roof cleaner.

RV Roof Specific

First off you need an RV roof cleaner to get your roof sparkling clean. While you may be thinking your standard dish soap will do the trick, RV roof cleaners do much more than just clean.

What’s more, if you are using a product that has not been specifically designed for your roof material, then you could end up doing more damage than good.

Protect

RV roof cleaners provide protection to help to keep your roof clean for several months. Not only does this improve your roof’s lifespan, it also makes the next time you clean it much easier.

Remove Stains

RV roof cleaners are formulated to remove RV specific stains, such as tree sap, mold and bird droppings, for example.

Using an RV roof cleaner ensures that you have the right cleaner to target these stains, for an easier clean, with less scrubbing. Using an ineffective generic cleaner could lead to you having to scrub your roof harder than necessary which can cause damage over time and lead to ingrained strains and a degradation of your roof’s protective covering.

Save Repair and Maintenance Costs

If your roof becomes damaged, either because you used an inappropriate cleaner, or you didn’t clean it at all, then you’ll be in for some costly repairs. Not only will you have to at the very least patch your roof, you’ll also probably have to repair the water damage internally from the leaking roof.

UV Protection

Most good RV roof cleaners provide UV protection to prevent the sun’s rays from aging and weakening your roof. If yours doesn’t, be sure to apply a separate RV roof protector after having cleaned, or opt for an all-in-one protect and care system.

Protect Your Investment

RVs are expensive, so is RV maintenance. So, why risk reducing the value of your investment for the sake of a few dollars and half a day’s work?

Keeping your roof in pristine condition will not only save you on costly repairs, it will also ensure that your RV holds its value. Whether it’s just for your own enjoyment, or if you want to RV share or upgrade someday, it makes financial sense to keep your RV in top condition.

Final Thoughts

There’s no shortage of excellent RV roof cleaners on the market.

When making your choice, be sure to first consider any cleaner’s compatibility with your roof type before committing to purchase. Then to find your best RV roof cleaner, consider which types and formats work best for you and your RV roof size.

For a rinse-free application, our favorite is the Protect All RV Rubber Roof Cleaner. The special non-abrasive formula is also biodegradable and non-toxic. It dissolves grime and chalk for sparkling results without needing to rinse. This cleaner will leave your rubber roof in great condition.
