Duro-last opinions needed

The employee running the robot welder was obviously not paying attention and the welder ran about 1" outside of the seam for about half the total lengths of the seams.  Do you think the welder running over the membrane outside of the seam creates a weak spot subject to premature failure?  Would love to post a pic, but I don't see how.  Thanks 

I think I would be more concerned about the seam itself. If the robot was ran one inch outside of the seam, you would only have a half inch or so of weld. Is there any scaring or signs of the iron dragging along the outside of the seam? Pictures would be beneficial. 

Yes, there is scaring outside the seam.  The membrane is melted, not entirely thru, about one inch outside of the seam.   I don't have the option to attach pictures.  Perhaps because I'm a new member.

Sounds as if the iron needs adjustment. How is the integrity of the seam itself? I've had tpo seams do the same thing and they are still watertight to this day.( 10 plus years ago) . Not pretty but still effective. There is always the option of overlaying those seams too. Where are you located?

The integrity of the seam is fine, my concern is the membrane near the seam that was heated by the welder would be a weak spot.   I'm in Cleveland Ohio.   I wish I could post a picture. 

I would think it should be ok as it's only a little scaring. Probably doesn't look the best however. Have you had issues before with this welder/ employee welding seams? I could send you an email address if you want to send a photo. Not much I can do here one hour east of Toronto but I can give you my 2 cents if that would help. Btw, took the wife to the rock and roll hall of fame in may and the people of Cleveland where very welcoming and accommodating. 

Sure, I'd like to get a picture to you if you can give me your email address.  Thanks.  Rock hall is pretty cool.   Most people in Cleveland are pretty nice.
