The victory has strengthened the Swans’ grip on a place in the top eight with six matches remaining before the finals.
The Swans took control of the match early, but despite the flying start the coach still believed his team had to work hard to secure the points.
“People will read that Carlton are down and all that sort of stuff," Roos said after the match.
"But I said to our players I thought they were up in the second half and really playing well, although Carlton fans might disagree.
“When they did come at us we were able to respond really positively and really quickly and that’s certainly pleasing.”
Adam Goodes was the driving force behind Sydney’s blistering opening, which saw the Swans grab a 33-point lead at the first change.
Goodes was well supported in attack by defender-turned-forward Rhyce Shaw, who booted three goals.
“I think individually some of the guys have worked their way back into some form, which obviously makes the team better,” Roos said.
Roos was also full of praise for young midfielder Kieren Jack, who held Carlton skipper Chris Judd to eight possessions in the first half.
“He is the sort of player that can turn it on and turn games,” Roos said. “It was a really important job that Kieren did on him.”
Although the Swans lost youngster Nick Smith to a hamstring injury, Roos is confident his team will improve further in the coming weeks.
Defender Lewis Roberts-Thomson, who was a late withdrawal from the side that beat Carlton after suffering a hamstring strain at training, should miss only one more game.
Key forward Daniel Bradshaw could also return from a similar injury to take on Geelong at ANZ Stadium in round 18.
But Craig Bolton (achilles) and Mark Seaby (broken ankle) remain long-term propositions.
“[Craig’s] rehab’s going as expected,” Roos added. “It’s more a matter of 'does the season run out before he’s over it?'
“You’ve got to get back running, which he is, then you’ve got to train, then it’s how long they train for.
“We’d expect him back, but not sure when.”
