An epdm rv roof ethylene propylene diene monomer or a tpo rv roof thermal poly olefin.
I have a bubble on my rv roof material.
May just be a bernoulli effect.
I two or three small pin holes where mosture could get in and make the bubbles.
What is you read more.
Vapour from contact bonding adhesive.
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.
Whilst bubbles or blisters on a one piece epdm roof can be unsightly they will not cause the rubber membrane to fail.
A roof blister is a raised area where there is a loss of adhesion of the roof.
The pressure in the camper will be greater and may be causing your rubber roof to inflate from the inside out due to the pressure differential.
This area can fill up with air or water to form a blister which looks like a bubble on your roof.
With only one bubble on your roofing material i would suspect that spot was contaminated somehow or not prepped thoroughly enough prior to the installation of the membrane.
The most common cause of roof bubbling is poor installation of the roof.
As the air flows across the top of your camper it creates a low pressure area just above the roof.
Does it eventually deflate when stopped.
The rv manufacturer simply didn t apply the adhesive evenly or left some dirt on the roof that the adhesive couldn t stick to.
Tom bubbles in epdm rubber membrane are typically caused by improper preparation during installation water intrusion or the use of incorrect adhesives.
Bubbles can also be caused by water getting under the membrane which shouldn t happen with a good installation but may happen if any of the seams develop holes.
Rubber tpo probably the most common material for an rv roof and actually comes in two different types.
I have a few bubbles on my roof on my rv.
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.
Should i cut the bubble in the middle and then tape and seal it.
