"it felt like the membrane was turning into chewing gum under our feet."
Yeah, that's exactly how it felt when we did mine a couple years back. Thought I was saving money doing it in July, but ended up regretting it halfway through. Starting super early did help a bit, but honestly, next time I'll just wait for cooler weather. Props to you for sticking it out though... roofing in mid-90s heat is no joke.
"Thought I was saving money doing it in July, but ended up regretting it halfway through."
Yeah, can confirm. We tried patching ours last August and it got sketchy fast—membrane felt way too soft. Is there even a safe temperature range for this stuff, or is summer always risky?
- Honestly, I've done TPO welds in mid-July without major issues.
- Trick is timing—early mornings or late afternoons make a huge difference.
- Also, membrane softness isn't always heat-related; sometimes it's just poor storage or material quality.
- Had a job last summer where the rolls sat in direct sun for days... total nightmare to handle.
- Bottom line: summer's doable, just gotta plan smarter.
- Good points, especially about timing being key. I've seen guys trying to weld TPO midday in August... looked like they were frying eggs up there.
- Agree with you on material handling too—had an inspection last year where rolls were stacked outside uncovered for a week. Stuff was practically melting in my hands.
- One thing I'd add: humidity can make things tricky even if temps aren't extreme. Seen welds fail inspection just because moisture got trapped.
- But yeah, summer welding's not impossible, just gotta be strategic and maybe keep a cooler nearby for sanity breaks...
- Good stuff here, humidity's definitely underrated. Had a job last July—temps weren't crazy, but humidity was brutal. Welds looked fine at first glance, but inspector found moisture pockets everywhere.
- Cooler breaks are a must, but honestly, at what point do you guys just call it quits for the day? Seems like after a certain temp, productivity tanks anyway...
