Best Caulk for a Leaking Motorhome Roof

[rdunnivan]

what type of caulking is best for motorhome roof, I'm getting a little leak, and want to replace the roof caulking as it's 10 years old.

Dicor self-leveling for level surfaces, standard Dicor for surfaces not level. I would NOT use silicone-type products on an RV_anywhere.
There's a reason silicone sealants are cheap.

What is the roof made of? I like Dicor products but the right caulk depends on the material that you will be using it on.

The sealants used may be specified by the OEM. RV make/model/year?

Dicor has been failing us for ever. Over a couple of years it will start to crack.
Use Sikaflex 715 and your worries are over. It is more expensive and a little more difficult to apply.
But will outlast you.

Think about using eternabind tape. It should last 20 years

I thought higher end RV companies are turning to self leveling silicone products

Did you read someplace about them using silicon products?

There is a reason products containing silicone are cheaper than other type sealants. Every heard of an RV mfgr. using the most expensive products on a production line?

AZ expert is a RV repair tech Youtuber and seems to be a decent repair guy, pretty sure he said some of the high end coaches are now using self leveling silicone products, just don't use one over the top of the other

Heng's Nuflex 311 Caulk Sealant

self leveling silicone caulk. 12 dollars per tube, not much of a savings
