Do hot air welded seams deteriorate over time?

No. Properly welded seams are stronger than the membrane itself and do not deteriorate over time. When comparing heat-welded seams to other thermoset seams, thermoplastic seams tend to last for the duration of the membrane’s service life, whereas in a thermoset membrane application, the seams are usually the reason why the roofing installation fails.
