Why new windows for leaking roof?

We just spent a ton of $ to have roof and siding repairs. The day after the repairs were finished, a huge rainstorm leaked water into our kitchen. The roofer did a water test and determined that the leak comes from two windows near but not at a point where the repairs were done. They gave us an estimate to install two new windows. They will not guarantee caulking.
Why do we have to buy brand new windows? Why can't we just re-install the ones we have? They are not broken, but the caulking is crummy.
Why didn't the roofer pick up on this before?

Was that leak there before? Was the contractor there to troubleshoot and fix “that leak”?

There is really no way to give you a accurate assessment without visuals.

Post a few pictures if you can, including a stand back shot of the wall from the window and up from the outside.

They probably leaked because they were not properly flashed. Caulk is not enough. The top must have an aluminum drip cap that goes under the housewrap/siding, and over the top edge of the window. The sides and bottom must be covered with felt or adhesive membrane tape, all this after caulking the nailing fins. If they are now telling you they will charge to do the job right, I would be very upset. And they did not do it right the first time, what guarantee is there it will be done correctly the second.

It very rare for windows themselves to be the source of a leak. The fact that you just had roofing and siding work done near there seems more than a little suspicious. Any siding work done around the windows should have incorporated the proper flashing, etc to seal that opening.
