How to maintain RV TPO roof?

TPO roofs are very durable and long-lasting, but they do require some maintenance if you want them to last as long as possible.

As you might imagine, a roof is one of the most critical components of your motorhome. From the waterproofing to the insulation and everything in between, you need a quality roof on your RV to keep the elements out and you safe. This guide will show you simple steps for maintaining your TPO roof on your RV to ensure a trouble-free and safe winter on the road.

What is an RV TPO roof?

TPO (thermoplastic polyolefin) roofing is a material used in camping and recreation vehicles to protect your caravan from weather damage. It’s often used as a replacement for traditional materials, such as asphalt or metal, on vehicles with domed roofs. The primary benefit of TPO is that it’s lightweight, yet still quite sturdy, making it ideal for travel.

With proper care, a TPO roof can last up to 15 years with no deterioration. Here are some simple steps that can be taken to ensure your TPO roof stays in excellent condition.

Clean the RV TPO roof

To protect your roof from damage, it’s important to properly clean it and regularly inspect it. TPO roofs are difficult to clean because they are sensitive to cleaners that could strip or erode their surface. Therefore, you should be sure to choose a gentle cleaning agent like soapy water or mild dish soap and never abrasive cleaners that could damage your roof. Your best bet is to use a solution made of one part water and one part mild detergent in a bucket.

Check for leaks and damage

TPO roofs are not as sturdy as some other kinds of roofs. Because they are low density and made from a single layer of plastic, TPOs can become damaged quite easily. If you notice any holes or leaks, get them fixed right away to avoid water damage that could spread throughout your home and cause extensive (and expensive) repairs later on. For minor problems, you can simply use tape; for larger issues, however, it’s best to have a professional come out and fix them. You can also use roof sealers for this purpose.

Apply protective coating if needed

TPO roofs are sturdy, but they’re not invincible. If you notice your roof getting dinged up from debris or if you live in an area with intense sunlight and extreme temperatures, it might be a good idea to apply a protective coating. This can help prevent further damage to your roof and extend its life. Many RV parks offer free coatings during seasonal maintenances.

Check and clean the drainage system

If your rig doesn’t have gutters or downspouts, check your TPO roof every few months to make sure water is draining well. Look around the edges of vents and at seams in between panels. If you find blocked channels, clean them out with a soft brush. Water can freeze into icicles and damage your TPO roof if allowed to build up over time.

Conclusion: How to maintain RV TPO roof

Maintaining a TPO roof is simple and cheap. Just spend your few minutes every month or two and perform small tasks that will make sure your RV’s exterior stays in excellent condition and no leaks appear. Before you start working on cleaning, remember to protect yourself against falling debris by wearing goggles and gloves, as well as long pants and sleeves. Make sure that you have all the necessary tools to clean properly without damaging your TPO roof more than it already is.
