We just purchased a 2003 Dutchmen and I finally got up to look at the roof. I noticed a couple spots where the caulking around protrusions through the roof has small "cracks" in it.

I would like to reseal it. What do I use to seal it? What's on there now looks like they just poured liquid onto the roof and allowed it to harden.

Go to an RV parts house (or go online) and get Dicor's sealant.  It is specifically made for rubber roofs.  Other sealants can damage the roof membrane.  Then just scrape off the old caulking, clean the areas thoroughly and lay down some fresh caulking.  It is a messy job but, if done right, will last for several years.

The spots I saw are just small "cuts".

Can I just reseal those areas without removing all the sealant?

Personally I have removed as much of the existing caulk as possible, clean the area really well - I've just used soap and water, apply as per directions and use a roller and some heat(hair dryer) to activate the tape and call it a day.  If it goes down properly it's the last time you'll have to touch the stuff  Smile
