- Retrofitting trusses into rafters sounds like a migraine, not just a headache... I looked into it last year for our 70s ranch and the quotes were wild.
- LVLs seem fine if you double up and don’t cheap out on connectors. My cousin’s got a green roof in Portland, still holding up after 5+ wet winters.
- I’d say it’s all about how much weight you’re adding and your local snow load. We went with beefier rafters and so far, no regrets.
- If you do try trusses, hope you like crawling around your attic for a while.
We looked at trusses too, but the price tag was a dealbreaker. Ended up reinforcing our rafters with LVLs and some extra bracing—definitely cheaper, though it took a few weekends. No issues so far, even after a couple heavy snow years. If you’re handy and patient, it’s doable.
That’s a solid approach, honestly. I see a lot of folks get scared off by the truss price tag, but LVLs and bracing can be a pretty smart workaround if you know what you’re doing. Around here (I’m in the Midwest), we get those wet, heavy snows too, and I’ve seen plenty of reinforced rafter setups hold up just fine—provided the work was done right and the load paths are solid.
One thing I’d add: not everyone realizes how important it is to check for any old rot or splits before beefing up existing rafters. I’ve come across jobs where people added LVLs but ignored some soft spots, and that’s just asking for trouble down the road. Also, don’t skimp on the connections—screws, hangers, all that. It’s not glamorous work, but it makes a difference when you get a freak snowstorm or high winds.
Trusses are great for speed and consistency, but if you’re patient and detail-oriented, reinforcing rafters can save a chunk of change without sacrificing safety. Just don’t rush it or cut corners... that’s usually where problems start.
That’s a good reminder about rot—seen a few projects where folks just slapped LVLs on, figured it’d be fine, and didn’t realize the old wood underneath was already shot. I usually go step by step: first probe every rafter for soft spots, then mark anything questionable for replacement, not just reinforcement. Curious, has anyone here tried using structural screws instead of traditional hangers for connecting LVLs to existing rafters? I’ve heard mixed things about their holding power, especially with older lumber.
I’ve run into this a bunch, especially on older homes where the rafters are already a bit questionable. I’ve used structural screws (like those big GRKs) instead of hangers a couple times, mostly when hangers weren’t practical because of weird angles or tight spaces. They do bite in well, but honestly, with old, dry lumber, sometimes you get splitting or the screw just doesn’t grab like it should. I still trust a properly installed hanger more for long-term support, especially if there’s any doubt about the wood’s condition. If I have to use screws, I’ll pre-drill and sometimes double up, but it’s always a bit of a judgment call.
