Lomberg cut it to 3-1 at 13:23 with a short-range backhand just under the crossbar.
Brandon Montour made it 3-2 at 16:19 with a slap shot from the left face-off circle. He extended his point streak to eight games (two goals, six assists), a Panthers record for a defenseman.
"It's nice to get milestones, especially with a franchise like this," Montour said. "My mindset, I'm just trying to make some plays, make something happen every time I'm out there, and things are going good, but wins are what matters right now. And we've got to find a way to get those."
Roy scored an empty-net goal at 18:58 of the third period to make it 4-2 before Verhaeghe scored at 19:26 for the 4-3 final.
"I think it was a bit of relief there at the end," Roy said. "We're glad we could get the empty net goal. We wish we didn't make it interesting there, but we're happy to get the two points and we're looking forward to tomorrow."
