After your business has suffered damage due to hail, assess your damage and determine if it is necessary to file a claim with your insurance company. If it is, then be sure to photograph and document the damage. Be thorough and specific.
Every insurance company will have its own process for filing claims. So, it is best if you reach out to the company directly to get the claims process started. Be sure to let your insurer know if the damage is severe and if the need is an emergency.
An insurance adjuster will then visit your commercial property. In the meantime, save receipts for anything you have purchased and repaired -- and keep a record of your claim documents.
Finally, wait for a claims decision from your carrier.
