You definitely should not allow them to try and put the old shingles they tore off back on the roof.  Make them provide you with new matching shingles to replace the ones they tore off.  

Or hire your own roofer to make sure it's done properly and send the bill to the company that tore your roof off.

That's a great Idea, Can also use that line to make sure they do the job right, Also hire an inspector to make sure they did the job right and bill them.
