That install day stress is real—I've seen more than a few folks pacing the yard while the torches are out. Did your crew use fire blankets or just go old-school careful? I always tell people, torch-down can be super reliable if the prep’s right and the crew isn’t rushing. Still, I’ve seen some sketchy installs where they missed flashing details and it turned into a mess later. Anyone else notice torch-down seems to hold up better on low-slope roofs, or is that just me overthinking it?
We had torch-down put on our garage a few years back—low slope, so it made sense. The crew used fire blankets and kept an extinguisher handy, which helped my nerves. I’ve seen it last longer on flatter roofs too, but flashing is always the weak spot if they rush.

That’s been my experience too. I did a torch-down on my shed roof with a buddy—took our time, but even then, the trickiest part was getting the flashing sealed up tight around the vent pipe. We used extra mastic and still had to patch a tiny leak after the first big rain. The fire risk made me nervous, but we kept a hose nearby and worked in short sections. Honestly, I’d be more worried about someone rushing than the torch itself.

Yeah, that’s always where I’ve seen problems crop up too. Even with all the right prep, those little gaps sneak in. I remember helping a neighbor with his garage roof—he thought he’d nailed it, but after a storm, water found its way right at the flashing. We ended up pulling it apart and using a peel-and-stick membrane under the torch-down, which helped a ton. Honestly, if you’re not patient with flashing, you’re asking for headaches down the line... fire risk or not.
Honestly, I’ve never bothered with torch-down for that exact reason—too many ways for water to sneak in, and the fire risk just isn’t worth it to me. I went with a self-adhered roll on my shed last year. Not perfect, but way less nerve-wracking and cheaper too. Maybe not as tough long-term, but I’ll take the trade-off for peace of mind.
