Best RV Roof Sealants

The type of sealant you need for your roof will depend on the type of roof you have. There are four main types of RV roofs: TPO (Thermal Poly Olefin), EDPM (Ethylene Propylene Diene Monomer), Fiberglass, and aluminum.

You may need a different roof sealant depending on the type of roof you have. Most RV manufacturers have a specific type of sealant they recommend in your owner’s manual. Here I will tell you what are the most commonly used sealants.

Quick Tips for Being on your RV Roof

Bring your tools up in a bucket

Instead of trying to carry your tools up the ladder, place your tools in a 5 gallon bucket and attach a rope to the bucket. When you climb up the ladder bring the other end of your rope with you. Then hoist your bucket of tools onto the roof.

Wear Solid Footwear

Use sneakers or shoes with good grip that are comfortable and not likely to slip off. Flip flops are a bad idea. Barefoot may not be too bad as long as it’s not too hot out and your roof won’t be heating up soon.

Wearing quality footwear with a good grip will reduce the likely hood of you slipping and falling while standing on your RV roof.

Use a Good Ladder

Sometimes our RV ladders are not in the best shape due to wear and damage. Using a ladder you feel secure getting on an off your roof with is important to help reduce the risk of a fall.

We use a telescoping ladder that easily fits into one of our storage compartments.
