How Do I Clean the Seal on My RV Roof

As the summer season approaches, it’s time to clean and prepare your RV for the camping trip of a lifetime. How do I clean the seal on my RV roof? It can seem like a daunting task with so many different types of products out there, but don’t worry! We’ll take you to step by step on how to do it right.

How Do I Clean the Seal on My RV Roof?

There are many ways to clean the seal on your RV roof, but they all require water. It’s essential not to jeopardize your valuable insurance coverage by making extensive changes to care for your surfaces, but it is also important to keep them protected from damage.

Clean your seal with these easy steps:

#1 Sweep and Inspect the RV Roof

Climb onto your roof and sweep the leaves and other bits off. Look for mold, mildew, or any other debris that is there. Check the caulk and seams of your house to see if they are broken or leaking. If so, fix them right away before the problem gets worse!

#2 Rinse the RV Roof Thoroughly Before Cleaning

First, rinse the seal with water to remove loose dirt and grime. If there’s a lot of buildup on the roof, cover your RV in plastic so that leaks will stay confined and won’t leave stains.

If you are storing your RV for a while, use the same process to clean it before putting it away. Remember that this is important if you want to keep any leaks from happening!

#3 Choose the Right Brush For the Job

When cleaning an RV roof, you can use a long-handled sponge mop to remove dirt and grime or even clean the roof from the ladder without the worry of slipping. For general spots, use a medium bristle brush. If there are tougher stains, use a soft bristle brush for scrubbing.

#4 Clean the RV Roof

To avoid falling and to be the safest while working around your RV, always clean in a back-to-front motion. Cover a size of 3 feet by 3 feet using a spray bottle. Clean in circular motions while applying pressure until the dirt is no longer visible, then rinse with the bucket.

#5 Rinse Roof and Sidewalls Thoroughly

After cleaning your roof, rinse it thoroughly to remove any excess dirt and grime. Be sure to clean the sides of the roof as well as the walls if possible; otherwise, residue can build upon those areas.

We recommend cleaning the seal around the roof from front to back while being careful not to slip and fall off.

#6 Gently Clean the Roof 

Gently clean the roof of your RV until it’s dirt-free. It may take a few cleanings to thoroughly clean the sealant on your RV roof, but it is worth the time and work.

#7 Clean Your RV Roof at Least Four Times a Year

It is important to clean your RV roof at least four times a year. If you do not, it can cause problems and the roof can look bad.

Regular roof cleaning helps you stay on top of maintenance and it can be a lot more pleasant when the RV isn’t full of dirt.

Types of RV Roofs

There are two different types of wood used for roofing materials, ethylene propylene diene monomer (EPDM) and thermoplastic olefin (TPO), each with its own maintenance routine.

Ethylene Propylene Diene Monomer (EPDM) RV Roofs

One of the most common types of roofs that are used on recreational vehicles today is made from EPDM or synthetic rubber. This type of roof has the ability to resist UV light as well as higher resistance to tearing and wear compared to its conventional counterpart, natural rubber.

Rubber sealant (usually an EPDM type) is used to keep water out of your RV. The sealant has superior strength and prevents chemicals from mixing with the liquid.

Water taints substances on an RV roof and leads to damage, so it is recommended that you choose only EPDM rubber roofs which will have less issue with water.

With their low-maintenance and easy-to-clean design, RV rubber roofs are an effortless way to maintain any vehicle.

Thermoplastic Olefin (TPO) RV Roof

TPO is a type of roof for RVs. They are made from plastic.

TPO membranes are single-ply roofing construction materials made from ethylene propylene rubber. They combine the durability of EPDM rubber with the performance of hot-air weldable seams. These TPO membranes have been tested and found to resist ozone, be resistant to algae, environmentally friendly and safe for people to install on their own roofs.

Why Does It Matter to Clean the Roof of an RV?

It is important to regularly clean your RV roof, as dirt and grime collected on the seal will make it brittle and susceptible to damage from rain or other external elements.

RV roof leaks can be disastrous. Small cracks and rips in the sealant put tremendous pressure on your RV’s structure, which can lead to major damage if left unhandled.

Water damage can threaten your RV in different ways. Damp areas will turn to black mold and fungi, which can result in health and respiratory problems.

How Can You Protect the Roof of Your RV?

Park your RV in sunny areas for increased dryness. You should also avoid parking in shaded areas and staying under trees as these cause leaks, including fruit and seed particles that promote roof moisture.

To properly clean your RV’s roof, you should do so at least four times per year and this helps reduce the negative effects that come from not cleaning.

If you live in an area with high levels of pollution, clean your RV more often to make sure there is a constant barrier against dirt.


Taking care of your RV is an investment into the comfort and safety of you, your family, and everyone who visits. Choose a durable roofing material that resists deterioration and use safe cleaning materials to keep it in top condition.

The sealant on the RV’s roof can be cleaned at home in a much shorter time and for less cost than repairing water damage.
