Rehabbing my garage wanted to know if it’s OK to remove the Cross braces left to right and front to back ![
You will not want to remove any of the rafter ties (as you called cross brace).
The rafter ties that span the horizontal distance from rafter tail to rafter tail at the side walls is what defines the triangle base of the rafter tie and its two mating rafters. Without that rafter tie the rafters can try to fold down and push the top of the side walls out. So do not remove these for the sake of your building integrity.
The spacing members that run parallel to and below the roof ridge line is equally important. It provides two main functions first of which is to keep the center top of the end walls straight and the front to back dimension of the building correct. Secondarily it ensures the spacing of the rafter ties and helps keep them directly under their mating pair of rafters. This can really help to keep things aligned if you ever decide to add a ceiling into the garage in the form of plywood or drywall.
No no no.
I have no idea why they didn't run a full length header but from your picture it looks like they laid 2 2x8s end to end to form your header and then sandwiched it with a 2x8 on each side. Guessing they didn't have anything that long in that size by the guy and they made due with what they had...
It wouldn't pass inspection now anywhere I have done work but it will be fine unless someone puts weight up there (shelves another floor) or if someone decides the bracing doesn't look good and takes it down.
Here is what will happen:
- You take brace off.
- The two 2x8 fall down.
- Your like well damn that looks better.
- Building survives.
- After a few months of wind hitting the building it shifts a tiny bit.
- Then you hit one of the sides with a wheel barrow... (dramatic pause) nothing. Imagine right before Jason kills everyone in the Friday the 13th movies you see someone get scared by a noise in the bush and it is just one of their buddies.
- Boom big storm goes through and your garage collapses to one side. No the walls won't splay out it will pick a side and go there and collapse like a house of cards.
