Rafters definitely give you more open space, but I’ve noticed they can get pricey, and you need to be careful with load calculations if you’re planning on a green roof.
Yeah, I’ve run into that a few times—folks get excited about the open attic with rafters, but once you factor in the extra lumber and labor, it’s not always budget-friendly. Did a job last year where the homeowner wanted a green roof over rafters, but after the engineer’s numbers came in, they had to beef up everything. Cost went up fast. Trusses are a lot simpler for most builds, just not as flexible if you want storage or a loft. Trade-offs everywhere.
Had a customer once who insisted on rafters for the “classic look,” then freaked out when the snow load calc came back. Ended up with more steel than wood up there. Anyone actually had trusses fail in a storm, or is that just urban legend?

I’ve wondered about this too, especially since I’m in a spot that gets a fair bit of snow every winter. When we bought our place, the inspector said trusses are “engineered for the worst case,” but I still get nervous when the wind howls and the drifts pile up. I haven’t heard of any actual truss failures around here, but I do know a neighbor who had rafters sag after a heavy storm—turns out the builder cut corners on the bracing.
I get the appeal of the “classic look,” but honestly, after seeing how much math and steel goes into making rafters safe, I’m leaning toward trusting the truss engineers. Maybe it’s just me being cautious, but I’d rather have something boring and sturdy than risk a roof collapse. Still, I’m curious if anyone’s actually seen trusses fail, or if it’s just one of those things people worry about for no reason.

That lines up with what I’ve seen—rafter issues from bad installs, but truss failures are super rare unless someone messed with them or the original design was way off. I’ve inspected a few storm-damaged roofs and, honestly, the trusses usually hold up unless there’s rot or someone removed a web for an attic conversion. It’s not impossible, but it’s definitely not common if everything’s built to code.
- Seen a truss snap only once, and that was after someone decided to carve out a chunk for extra storage—bad idea.
- Most of the time, it’s rafters sagging or twisting after storms, especially if shortcuts were taken on bracing.
- Trusses are like the quiet kid in class—don’t mess with them and they’ll never cause trouble.
- But yeah, rot is the silent killer... found one where squirrels had chewed through and water got in. That was a mess.
