A roofing contractor will come evaluate your roof, and suggest whether you’ll want to report the incident to your insurance provider. The Insurance will then appoint a claims adjuster to come to your house and do their own inspection. A qualified contractor will know what is consistent for a claim, and ensure all the damage to the property caused by the storm is covered. It is likely that the adjuster may not find everything, but a good contractor will work with the insurance claims department to determine all justifiable items.
The contractor sends his proposal to the insurance company, and once everything is agreed upon, it is time to have your roof replaced.
Please know that your insurance adjuster and the insurance company always have the final say if your claim actually gets approved or not.
