“How often do I need to reseal my RV roof?” It’s case by case, roof by roof, of course, but the recommendation is to reseal your roof every year.

Failure to do so will cause leaks. Have you ever had your ceiling leaking so much that you can take a shower inside every time it rains outside? We want to avoid that.

As we all know it is very important to use the right kind of tools for any job. That said, first, you will need a tool to remove the old sealant from the roof.

Second, you will need the proper sealant. For roofs, you will only want to use lap sealant self-leveling 501LSW. There are a couple of manufacturers that make this product. I usually use Dicor Products. You do not want to use silicone caulk or tars. The reason you do not want to use other sealants is that they become very hard to remove in the future and they also don’t have the self-leveling feature.

Third, you will need a good caulk gun.

It will take a few hours to remove all of it from your roof. Remove as much as you can. Truthfully, it is nearly impossible to remove every bit of it. Removing all that you can, no matter how hard it may be, will make it easier to apply the new sealant.

Apply a thumb-sized bead of sealant evenly over all the areas you removed the old sealant. It will not hurt anything if you put a bit more sealant than you need. Most important is that you cover every edge well. We do not want you leaking anywhere! No indoor showers in the kitchen or bedroom!

Hopefully, this will help get you on your way to resealing your roof on your own.
