Rubber Roof Has Bubbles

Definitely keep and eye on it and if it begins to get larger i would take it to the dealer.

Rubber roof has bubbles. In time the bubbles will decrease as the membrane is partly breathable. If this is the problem the solution is to install pressure relief vents. In the most severe cases the membrane may need to be peeled back and re bonded. This can occur for two main reasons.

A roof blister is a raised area where there is a loss of adhesion of the roof. Vapour from bonding adhesive bonding adhesives are used to attach epdm membranes to upstands and around the roof perimeter. When the rubber membrane is bonded too quickly and prior to the adhesive drying bubbles will appear under the membrane caused by the trapped vapour from the adhesive. Whilst bubbles or blisters on a one piece epdm roof can be unsightly they will not cause the rubber membrane to fail.

These bubbles of trapped air moisture can be caused by a variety of issues which are all avoidable if the roof design is correct and the membrane is correctly installed. The rv manufacturer simply didn t apply the adhesive evenly or left some dirt on the roof that the adhesive couldn t stick to. Most epdm and tpo roofs will have some bubbles wrinkles at least every rig i have had did and so do most of my friends rigs. Usually bubbles are not associated with leaks.

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. If left untreated a blister can grow larger and allow more moisture to get in so that the problem gets worse until more extensive repairs and possible replacement is necessary unless it pops. In some cases a contributing factor can be high pressure in the roof system. The most common cause of roof bubbling is poor installation of the roof.

This area can fill up with air or water to form a blister which looks like a bubble on your roof.
