substandard contractor work?
#7
  
I had a flat rubber roof replaced at work and I have some concerns about quality of workmanship.  The first half of the roof they put down was a fairly cold day with the temp between 37 and 42 degrees.  There are some bubbles under the rubber that I am concerned about. The contractor said that the adhesive went down a little thicker than they prefer because of the cooler temps and the bubbles I see are from the off gassing of that thick adhesive layer.  He claims that the gasses will "seep out"  with the temperatures get higher".  The temperature has been typical New England weather with some day in the 30-40's and some has high as 70 degrees.
He is expecting full payment since he has finished the work.  My questions is: should I accept his explanation?  Should I be concerned about the quality of his workmanship, the second half of the roof looks perfect.

Is that EPDM? 

We have some bubbles on our roof, not nearly as bad as yours though...

What kind of warranty? I think ours was 15 years...

I would find out what brand of roofing the contractor used... Firestone or Carlisle etc... and send that manufacture a picture of the installation asking them if they would have any problems honoring the warranty of the installation.  If they are ok with it, then your ok.

This  ^^^^^^^^^^^^^^  But get it in writing from the manufacturer.

...

Perhaps he right, but common sense would ask if the roof is water tight, one would think that it's air tight as well.

Unless the gasses "seep" into the structure, and not through the membrane.

Doesn’t matter if you send pics. Both Carlisle & Firestone whom also manufacture versico and mule hide will tell you the contractor is correct about the gassing off. That said there are a few more blisters than an experienced crew would have had regardless of temp.
