These are just a few of the things that you need to do to maintain your TPO roof. By following these simple steps, you can extend the life of your roof and avoid costly repairs.

It is important to clean your RV TPO roof regularly. This will help prevent any build-up of dirt or debris and extend the life of your roof. The followings are some tips on how to clean your TPO roof:

Use Only Non-Corrosive Rubber Cleaners:

Roof Scrub in Small Sections:

When scrubbing the roof, it is best to work in small sections. This will help to avoid any streaking on the surface of the roof. Additionally, it is essential to rinse the roof thoroughly after scrubbing to remove any cleaner left behind.

If you follow these simple tips, you can keep your TPO roof clean and extend its life. By regularly cleaning your roof, you can avoid any build-up of dirt or debris and prevent any future damage from occurring.

There may be some confusion regarding the materials used to make RV roofs. A roof’s type will significantly impact how you maintain it, so you must choose the right one for your situation. Common RV roof  materials include:

01. Thermoplastic Polyolefin (TPO):

TPO roofing is known for its durability and resistance to UV rays, making them a good choice for RVers who travel in sunny locations.

You can easily walk on TPO when wet since it is not slippery, and if you pull off the vent shroud, white roof material should be seen on the underside. Furthermore, TPO tends to exhibit a higher shine.

02. Ethylene Propylene Diene Monomer (EPDM):

EPDM is a synthetic rubber membrane that is made of ethylene and propylene. It is black in color and has a smooth, glossy surface. EPDM roofs are trendy on RVs since they are easy to install and are very durable.

These roofs can be walked on when wet, and they are also resistant to UV rays. However, they can be damaged by chemicals, so it is important to avoid using any harsh cleaners on them. If you pull off the vent shroud, black material should be seen on the underside. 

03. Almunium:

Aluminum roofs are made of, well, aluminum. They are often used on commercial buildings and are very durable. Aluminum roofs are reflective, so they can help to keep your RV cooler in sunny weather.

When wet, these roofs can be walked on, but chemicals can damage them. If you pull off the vent shroud, metal roofs material should be seen on the underside.

04. Fiberglass:

Fiberglass roofs are made of, you guessed it, fiberglass. They are often used in RVs and are known for being lightweight and easy to install. Fiberglass roofs are white in color and have a smooth, glossy surface.

These roofs can be walked on when wet, but they are not as durable as some of the other options. White material should be seen on the underside if you pull off the vent shroud.

These are the most common types of RV roofs. It is important to choose the right one for your situation. If you are unsure, you can always consult with a professional to get the best advice.
