Buying Guide

RV roofs need to be protected from the elements. I once used a sealant to fix a leak on my camper.

Here’s a guide to help you choose the best RV sealants.

  • Type of Sealant: There are many types. Some are for flat roofs, and some are for other areas.

  • Material Compatibility: Make sure the sealant works with your roof. Check if it’s for EPDM, PVC, or other materials.

  • Weather Resistance: Pick a sealant that handles all weather. It should work in both hot and cold conditions.

  • UV Protection: Choose a sealant that blocks the sun’s rays. This will help it last longer.

  • Ease of Application: Consider how easy the sealant is to use. Some are self-leveling, which makes the job easier.

  • Color and Appearance: Think about the color of the sealant. White sealants can help keep your RV cool.

  • Durability and Longevity: Look for a sealant that lasts a long time. This will save you from having to reseal often.

  • Size and Quantity: Decide how much sealant you need. Buy enough to cover the areas you want to seal.
