I hear you on the fire risk—torch-down always made me uneasy too, especially after seeing a neighbor’s place get scorched during a rushed install. I ended up going with a single-ply TPO system for my own flat roof, partly because it’s heat-welded and doesn’t involve open flame. It cost a bit more up front, but I liked that it’s reflective and helps with summer cooling. Still, I’ve seen torch-down last decades if it’s done right... just not sure I’d ever be comfortable with it on an old wood deck like mine. Maintenance is definitely the name of the game with any flat roof, though—no escaping that.
You made a smart call, honestly. I’ve inspected a lot of torch-down jobs over the years, and while some are textbook perfect, all it takes is one careless installer or a windy day and things can go sideways real fast. Saw a place once where the crew tried to torch over a damp deck—what a mess. The fire risk is real, especially on older wood structures.
TPO’s definitely gained popularity for good reason. That heat-welded seam is a game-changer, and the reflective surface really does help with cooling costs in the summer (especially if you get full sun like we do out here). I get why folks still go with torch-down—if it’s installed right and you stay on top of maintenance, it can last—but I’d be just as nervous as you about open flame around dry timber.
Maintenance is always going to be part of the deal with flat roofs, no matter what system you pick. Sounds like you’re on top of it, which is half the battle. Peace of mind counts for a lot... sometimes spending a bit more up front pays off in sleep later.

Couldn’t agree more—sleep is underrated until you’re lying awake picturing your roof on fire. I went TPO last year after seeing a neighbor’s torch-down job go sideways (let’s just say the fire department got a workout). The cooling savings are real, but honestly, not worrying about a stray spark is worth every penny. Maintenance is still a pain, but at least it’s not a four-alarm one.

That’s the part that gets me. I looked at torch-down because it was cheaper, but honestly, the fire risk just kept nagging at me. I ended up patching my old built-up roof instead—less ideal, but I couldn’t swing TPO prices. For folks on a budget, is there any safe way to do torch-down, or is it just not worth the gamble? Maintenance is annoying, but I’d rather deal with leaks than flames...
I get the fire worry, but I wouldn’t write off torch-down completely. There are “cold-applied” modified bitumen systems that don’t use an open flame—just adhesives. Not quite as cheap as torch-down, but still less than TPO or PVC. I’ve seen some folks have decent luck with them, especially on smaller roofs. The trick is finding a crew that actually knows what they’re doing... which isn’t always easy, I’ll admit. Anyone else tried those cold-process options?
