It might be very stupid an amateur question. My apologies in advance. I’m boarding my garage to create some space for storage. There are some perpendicular bracing which are attached to wal plates. There are two diagonal ones which are not attached to wall at all. I’m putting new joists perpendicular to present ones and these two diagonal braces are on the way. Would it be safe to assume they are remnants of temporary braces and remove them. The roof itself has cross bracing separately.
