Yeah, that's pretty common actually. I've seen a lot of roofs where the seams look perfect at first glance, but after some weather cycles, little issues pop up. Good thing your roofer came back quickly—that's usually a sign they're solid. I'd say you're doing exactly the right thing by keeping an eye on it after storms or big temp swings. Roofs can be finicky sometimes, but sounds like you're on top of it... pun intended, haha.
I've seen that happen too—had a friend whose TPO roof looked flawless until summer hit hard. Turns out the installer had welded it way too hot, making it brittle. Curious, did your roofer mention anything about ideal welding temps? Seems like there's a sweet spot there...
I've heard installers mention around 900-1000°F as a general range, but honestly, it depends a lot on weather conditions and even the brand of TPO. Did your friend's roofer say anything about adjusting temps based on material thickness or ambient temp?

When we had our TPO roof installed last summer, the installer definitely adjusted the welding temperature throughout the day. He started around 950°F in the morning but dialed it down to around 900°F once the sun was directly overhead and heating things up. He mentioned that thicker membranes sometimes need slightly higher temps, but mostly it was about checking seams regularly and tweaking as needed. Seems like it's more about experience and feel than sticking strictly to a number...

Yeah, that's pretty much what our installer did too. He mentioned something similar about thicker membranes needing a bit more heat, but mostly he just kept an eye on how the seams looked. Seems like it's more art than science sometimes...
