Blisters come up at night---go away in day if warm sun is present;
JM cold applied sbs, torch seams.
blisters are present by the 1000's,all over the roof(700 sq). Anybody seen this or know anything about night time blistering? call 903-590-6254

That's wild. Just the opposite of a normal blister.
My guess, if this is new, venting adhesive gasses are not pushing out at night, but for some reason the day time heat is allowing it to gas off, or force into the iso.
Or, you have poor adhesion/poor adhesive distribution. In the heat, the adhesive and membrane are relaxed, fluid and blisters are less visible. At night when the adhesive solidifies, the bond is more aggressive at the borders of the bond and therefore more visible.
I'd take core cuts at night, and mark some areas to take core cuts during the day.
