Fixing hail damage on cars

If it's an accredited repair shop, it will have the experience and skill to do the work. Body repair shops remove and replace panels all the time. It's not a concern as such, and done as a matter of course these days rather than panelbeat the roof to rid it of the dents as might have been done in the past. If the work is done correctly the structure of the vehicle won't be affected, and I would certainly have it done. I assume it's covered by insurance, so you have comeback on the insurance company if the work isn't done well. And resale value will be much better without dents in the roof.
