I recently bought a house that has above the garage-door storage.
This is hanging from the roof, which means that if you look at the house from the street you can see very faint waviness because the 2x6s supporting the roof that the garage hangs from are unsightly. In talking to our home inspector he suggested it wasn't a structural problem but just a "it might be nice to fix" issue. It is 1/2 mounted off another support beam running the length of the garage, only the cantilevered part is hanging from the garage.
Some pictures to better explain
There a total of 6 of these supports, in three groups:
I'd like to better support this. The garage door is awkward, though, because I can't just put a support under the corners of the platform.
Is there a good approach to supporting this? My gut is to run a beam across the edge furthest from the existing support and support this from the floor of the garage. It's about 20 feet across and I'm not sure I can get a solid 20' continuous beam up there without hacking pieces apart, whether disassembling the garage door or taking supports off entirely. I could then fasten the floor up to the beam.
Putting a beam under the platform will give me minimal space (if you look at the first image you can see how close to the bottom of the platform the garage door comes).
I'd guesstimate it only really has to support 500-1000 more pounds than the platform, for storage purposes and supporting the weight of someone being up there.
Any suggestions would be appreciated. Hoping to avoid taking most of it down..
