Narrative:

Roa tower closed at XA00. Cargo aircraft delayed by WX but received clearance before tower closed. Without getting a release from ZDC, aircraft took off. No loss of separation. It should be understood that, when a tower closes, that any clearance issued by that facility is automatically canceled.
