As our building was a victim of Irma, I can attest that you must move forward with repairs, memorialize all damage for insurance and have them appraise loss and move forward and submit repairs to insurance.
You cannot wait Will only cause more damage by mold, rust etc.
We are doing that now. Huge job. Landscaping, lobby destroyed, dry wall gone, trim gone from elevators. All ground floor electrical destroyed, cctv etc. Security.
You cannot wait.
Good luck
