WHM will generally send you an email advising if a certificate is expiring. To recreate it all you need to do is:
Login to WHM
Go to Service Configuration >> Manage Service SSL Certificates
Click on 'Reset Certificate' next to the ones that are listed as expiring (usually all of them will expire at the same time).
