That's not a gable roof. It's a hip roof.
Modifying Roof Structure
Hello All,
I've lurked a lot here but never posted. Well, i fear I am just educated enough to ask a few questions.
I bought a 1970's built home in Southern California and it's been one project after another. Most recently, i decided to tackle the garage as the last guy who lived here was an engineer that screwed basically everything up. I am a crappy person to judge this (as I'm still new to this type of stuff) but his logic made no sense to me.
My roof is gabled. It has standard 2x8 rafters and a ridge beam with 2x4 rafter ties at the top plate. Well, the guy before me threw in super flimsy 1x6 (Douglas fir?) collar ties with 2x4" vertical supports from the rafter down to the rafter ties. He then build plywood storage on the rafter ties and sagged them.
I removed all the storage (aside from the rafter ties/collar plates as they might be original?) and built my own. I framed 2x4s in place of the old flimsy 1x6 (collar ties) and sandwiched the rafter with them. I then used 2x4s to build a horizontal framing structure from 3" above the top plate on each rafter out to supports dropped from the new, sandwiched collar ties.
I also tied the collar ties to the ridge beam and other rafters for support. I really wanted to remove my rafter ties now that I have decked in all my framing/storage with 1/2 Plywood (I hate the look of the sloppy, sagging ties blow my new framing) but understand they serve a purpose to keep the walls from pulling apart. I may end up re-doing them.
I went ahead and built all this before reading up too much on it as i feel i braced it enough and won't be loading more than a few hundred pounds on it but wanted to post it up to get everyone's thoughts. Now that I've read up a bit more, I would've done it differently but it's done and, 10lbs. of 3.5" structural lag screws later, it's not going anywhere without a fight. I want to ensure the way i built it won't cause my roof to sag or have issues and appreciate any guidance you guys can offer.
