Roof question?

[Fireguy205]

This is my friends roof, he has had the tt for 2 weeks. He sent the picture to his salesman who said that it is normal for this to happen from time to time. Anyone have any info? TT is a Coachman Apex 289TBSS.

Anyone have a BS flag to send to the salesman? I owned a TT 6 years without a single bubble.

Yeah, I am no expert, but looks like trouble to me.

My roof has air bubbles. Is this normal?

Typically, if air bubbles occur they occur during or very soon after the roof has been applied. A couple of reasons for the air bubbles would be that they were not broomed out during application, and we ask the installer not to stretch the material during installation to allow for expansion and contraction of the membrane. Air bubbles will occur with weather conditions and humidity. Air bubbles can also occur at the seams of the roof decking due to flexing and twisting that occurs during transit. Sometimes they occur if there is a significant difference in the temperature between the inside and outside of the unit.

Will the air bubble effect the performance of my roof?

No. The air bubbles will not blow up and pop. They will come and go with the weather conditions, humidity, etc. Please do not puncture the air bubbles. Air bubbles mean there is room for expansion and contraction, lessening the chance of stress cracks later.

No it's not normal. my Wildwood TT had bubbles on roof took to my dealer he says
factory did their half*** job not enough adhesive under roof membrane. Dealer put new
roof on TT under warranty now tight as a drum.

The bubbles typically occure under three conditions, the membrane adhesive was not properly dry ( solvent based adhesive), the membrane adhesive was not adequately applied or the membrane did not make proper contact during the installation process.

The bubbles could become problematic if they continue to expand especially during high air prussure conditions or when you are driving the unit. I would have them taken care of before they do become an issue. The delamination issue will likely expand and a larger area of the membrane will then become detached from the substrate.
