Due to the establishment of many companies in the town and nearby areas, huge employment opportunities got generated which ultimately led to the growth of the infrastructure because of unending demands of accommodation for workers, employees, officers etc.

As per elderly citizens of Sikkim, Rorathang was one of the large and very old market that was nearly 1-2 kilometres away from the present day town towards Pithang at the bank of river Rangpo.

After massive destruction, slowly again new settlement started in the present day Rorathang, as it was bit high in altitude than the old town and therefore less vulnerable to flash floods.
