After struggling in the first half, Auburn trailed 24-0 in the second quarter and was behind 24-7 at half with the Tigers looking anemic on defense.
However, in the final two quarters the Crimson Tide managed only 67 yards and three points and those points came as a result of a fumbled Auburn punt.
"To be down 24 when they had a 20-game home winning streak going and to come back and fight through things we had to fight through was really just a microcosm of our season," Roof said.
"We have done this over and over again," Roof added. "Our kids did a great job in the second half after the adjustments were made. They came out and played like they can play. I am really proud and happy for them. I am happy for all of our Auburn people, too. This was a big win for us."
The Tigers gang tackle Alabama running back Trent Richardson in the second half.
Head coach Gene Chizik credited the assistant coaches with making good halftime adjustments. Asked about that, Roof said, "We had to get a feel and a flavor for what they were doing because they were doing a bunch of new things that they had not shown before.
"Our kids did a great job of adjusting to it and came out and made the plays they were in a position to make," Roof added.
"I tell you what," Roof said. "It really starts with what Antoine Carter did with that fumble. When that kid (Mark Ingram) broke. To chase him down was kind of the start to getting our feet back up under us. That was a huge play in the football game that may get lost because of what happened in the second half. Looking back, that was a critical piece to this win."
Roof said the victory over Alabama that improved the Tigers to 12-0 was a true team victory. "The strength of this group is the team and that is what really makes it so fun. They care about each other. They play for one another. We are a team. That is what we are."
