“If the flat glass at the edges of where it’s broken are curved up, that indicates something internally caused the glass to break—a defect in the glass,” said Pete Daly, the president of Paymer & Phillips Auto Repair in Laurel, Md.
In his 20 years in the sunroof repair business, Daly has seen plenty of these defects. He says techs at his shop fix blown-out sunroofs on a regular basis, many of them from customers that claim explosions.
“It doesn’t matter what make or model or what sunroof manufacturer—they all have these problems,” Daly said.
