price to have a roof resprayed

Have some rust on my roof along the window edge, and the general opinion is I need the whole roof resprayed.

What do you think I should expect to pay for this?

Also, may get the front and rear bumpers done.

has anyone had this done?

 

300-500 for the roof 100-150 for the bumpers assuming no welding on either

 

if that is the cost that would be great. Could even get it done with a metal flake again for a little bit extra
