Hail dented my Lawrence garage door. It still works. Do I need to do anything?

You need photographs and a verdict, and possibly nothing else. Dents that do not crease the panel skin, rack the sections, or break the seal are cosmetic, and the legitimate scope is documentation: dated photographs of every panel for the house file and for any future claim comparison. What deserves attention is the damage hail hides: a creased top section that will fatigue, a window frame cracked at a corner, a bottom seal torn where debris struck. A service visit that reads the door panel by panel and writes cosmetic beside the honest dents has done you a service, even when the invoice total is small.
