Insurance companies want you to have a competent roofing company go out and assess your roof damages before sending their adjusters. They do this because they want to know if you actually have roof damage or it may be something else unrelated, If there is damage they want to verify wether it is storm damage or mechanical damage, wear and tear etc.
Once the roofing company determines you have incurred storm damage to your roof, you then want to start getting your insurance company involved. If you need help with this process feel free to reach out.
