irrespective of the contractor/ contractee relation, if any third party visitor meets an accident within the premises, then its duty of the occupier to offer these measures to safeguard the life.
later on you can discuss the issue with legal entitlement, hope the contractor person is covered under the ESIC benefits. so they can file an accident report to esic under form 12 online or offline stating that during inspection of site, the incident happened.

The visitor / person (not a contractor) had come to see the place before giving his quotation / rate for contract work. The person has neither Principal employer - Contractor relationship nor employer - employee relationship with the Company. You will have to send accident report to the Factory inspectorate, who will trouble you as to how that person was allowed to climb on the roof without proper safety measure. Pl consult some good lawyer who is well versed in such cases w.r.t payment of suitable compensation, in case if there is any claim from the deceased person's family.
