The adhesive is solvent based and must be allowed to gas off and become touch dry prior to bonding the membrane into position.
Liquid roof bubbles.
Usually bubbles are not associated with leaks.
Vapour from contact bonding adhesive.

I applied the liquid roof to my heartland trailrunner one month ago.
Liquid rubber provides a seamless single coat roof coating that can be applied up to 6 times thicker than your standard elastomeric.
If there is water trapped within the roofing structure or the timber isn t completely dry when the membrane is applied this can also cause bubbles and blistering to form.
This area can fill up with air or water to form a blister which looks like a bubble on your roof.
Contact bonding adhesive is used for bonding the rubber membrane on upstands and around the perimeter of the roof deck.
Roof bubbling is just what it sounds like spots where the rubber has lifted off the surface of the roof and formed a bubble or blister.
If the rubber is bonded prior to the adhesive drying then bubbles will appear under the membrane caused by the trapped vapour from the adhesive.
Will they go away.
The most common cause of roof bubbling is poor installation of the roof.
In some cases a contributing factor can be high pressure in the roof system.

Liquid rubber will withstand ponding water or immersion indefinitely and liquid rubber can be installed over lightly rusted surfaces without a primer.
The most common cause of bubbles is the application of rubber to the deck or insulation board too soon before the adhesive is dry enough.
I suggest that you call the manufacturer of the membrane and talk to them about it if you can do so.
Tough to do much now.

A few bubbles near the edges or where there is caulking is pretty normal but it should take years for any of them to get larger if at all and the footprints would be completely unacceptable to me.
The rv manufacturer simply didn t apply the adhesive evenly or left some dirt on the roof that the adhesive couldn t stick to.

A roof blister is a raised area where there is a loss of adhesion of the roof.
This happens when the roof heats up the water evaporates and the vapour has nowhere to go.
Roof bubbles present one month after application.
You probably won t need any patch material.
