Once the walls are finished, all that's left is the roof. The carpenters build the roof truss from thick beams. The small crane helps them by lifting the thick roof beams into place. Then the roof is sealed and the roof battens are installed. Finally, the roof tiles are laid and the roof is complete. The shell of the building is now finished.
