How to Reseal a Travel Trailer Roof | My Guideline

Fixing up the roof of your travel trailer is about more than just doing maintenance. It’s about getting your trailer ready for all kinds of weather while you’re on the road. Resealing the roof puts a protective coat back on so water can’t get in and damage your trailer. It helps stop leaks and keeps you safe and comfortable inside.

Resealing means putting a fresh layer of sealant on your trailer roof every few years. Old sealant cracks over time and lets water and dampness in. By scraping the old sealant off and adding new coating, you plug up those cracks. Adding new sealant keeps rain out and protects your trailer from sun damage too.

Following the right steps to clean and reseal the roof isn’t hard to do yourself. Taking good care of your trailer means you’ll get many more years of enjoyment out of it. Resealing the roof gets your trailer ready for new adventures on the road while keeping you nice and dry inside when bad weather hits.

What Types of Roof Materials of Your RV Have?

There are three main types of roofing materials used on RVs and camper trailers:

TPO (Thermoplastic Polyolefin): TPO is a single-ply roof membrane typically bright white in color. It is durable, flexible, and reflective.

EPDM (Ethylene Propylene Diene Monomer): EPDM is a popular rubber roofing material known for its flexibility and weather resistance. It comes in both white and black colors.

Fiberglass: Fiberglass roofing involves a fiberglass base reinforced with additional coatings and sealants. This option is lightweight but more easily damaged.

A small comparison between TPO vs EPDM

TPO and EPDM roof materials are two common options with key differences:

Attribute	TPO	EPDM
Cost	More expensive upfront	Lower upfront cost
Weight	Lightweight	Heavier than TPO
