License Information

Wonderlin Roofing Systems Inc. is fully insured with General Liability, Worker’s Compensation, and bonded. Says Grover: “While most companies carry worker’s compensation for their employees, less than 10% carry general liability insurance because of the expense. The danger in using those companies that ‘go bare’ is that if anyone is injured during the re-roofing project & or property is damaged, the homeowner can be brought into a time consuming and expensive lawsuit.”
