The acutal garage only starts at where you can see the first rsj. The previous owner looks to have knocked down the rear of the garage then extended with timber and used corrugated metal sheets as another roof.
Bought a house, which has a lean to garage with RSJs and concrete roof. It's missing the back and roof is leaking so rusting has occured in the beams. Any ideas for the missing back and if the beams are safe? New to this, any guidance would be appreciated
