225 ILCS 335/3.2
Before issuing or renewing a license, the Department shall require each applicant or licensee to file and maintain in force a surety bond, issued by an insurance company authorized to transact fidelity and surety business in the State of Illinois. The bond shall be continuous in form, unless terminated by the insurance company. An insurance company may terminate a bond and avoid further liability by filing a 60-day notice of termination with the Department and, at the same time, sending the notice to the roofing contractor. A license shall be cancelled without hearing on the termination date of the roofing contractor's bond, unless a new bond is filed with the Department to become effective at the termination date of the prior bond. If a license has been cancelled without hearing under this Section, the license shall be reinstated upon showing proof of compliance with this Act.
