Fatal ** GetSurfaceData: Errors discovered, program terminates

when i try running energyplus simulation on individual floor it runs successfully and i get the output but when i try to merge all the floor together to get the output of one entire building block the following error pulls up
“1. The simulation has failed because of this fatal error:
** Fatal ** GetSurfaceData: Errors discovered, program terminates.”
There is a problem with the roof surface.
is there any solution to solve the surfaces quickly.


Please help me in solving the equation i’ll be really grateful.
