Roofing Failure Need Help


Our church had torch down (5 yr warranty one ) and 2 years later there's splits and cracks . What could have caused it . One of the splits looks like not enough heat was applied because you can see the labels in the bottom which usually gets melted to adhere to the base membrane. We had a well known roofer do the work but maybe the worker doing the torching got lazy towards the end. All areas failing happened in the higher end of the roof lower slope perfect nothing failed but the higher end failed. Just need some of reason why could have failed.

Re: Roofing Failure Need Help


He said what I expected , he will make it water tight because it's raining Thursday and Friday. But he said he will contact manufacturer of materials and have them come out and take a look at it. He also said one cut could have been vandalism because cut looked to sharp of a line like it was made was the a utility knife. I'm just trying to figure out ideas why it failed , my feeling is not enough heat applied to it but I need input from roofer who have done torchdown and why it fails etc...

That looks structural--or just a faulty roll.

Re: Roofing Failure Need Help


I guess my question is what happens if the roll is not heated enough.

No, based on the picture it seems that it is adhered properly.

And if you don't apply enough of heat, it wouldn't crack just like that but you'd rather see wrinkles/bubbly membrane which it isn't.

Did they torch down over metal by any chance?

No over old roof. But the big cracks when we pulled it apart the labeling under was never melted which told me not enough heat. The other spots I agree adhered proper but may have faulted .

Re: Roofing Failure Need Help


What kind of underpayment? It sorta appears the roof may have been wet when applied?
