Installing OSB subfloor in garage attic
The 2x4's flat on the joists are temporary if you install sheathing . The center 2x4 under the 1x ridge board is temporary when installing the rafters. You can remove them BUT the joists will move so sheet up to them and nail the decking off before removing the flat 2x4's. And you door top track and opener is attached so be careful that the joists will not move during decking.
They are made to carry their own weight and span the distance. They already carry the garage door when open and the opener. You would need to weigh the door and opener to subtract it from the total load they could carry. I would use real ply as it is 15% lighter than OSB.
Be safe, Gary
Clothes taking longer to dry?
Clean the dryer screen in HOT water if using fabric softener sheets.
They leave a residue that impedes air-flow, costing you money.
Clean the ducting in the last six months? 17,000 dryer fires annually!
