After clinging to a vital three-point victory against Sturt in Round 8, the Roosters banked their second win in succession to cement sixth spot and get within a win of fifth-placed Norwood.
Leading at every change, the hosts made the most of having just four more inside 50m entries than the Crows as Will Combe and Dyson Hilder booted three goals each.
But the margin was set to be significantly more before Adelaide outscored North by two goals in the fourth quarter to peg back the 52-point deficit at the final change.
Experienced North recruit Aaron Young exploded for 30 disposals, eight marks, eight clearances and six tackles as teammates Andrew Moore (26 disposals) and Campbell Combe (25 disposals) worked hard in the clinches.
Left-footers Jarred Allmond and Harrison Wigg collected 24 possessions each while Kym LeBois returned to form with 20 disposals, nine marks and two goals for the Roosters.

After losing two matches in a row in Rounds 5 and 6, the Eagles have now got their season back on track as they solidified their place inside the top three.

Jake Von Bertouch presented well for the Eagles, nailing two of his three goals midway through the first term as crafty small forwards Daniel Menzel and Tyson Stengle kicked two goals each.
It was an even spread of contributors through the midfield for Jade Sheedy’s charges as Dane McFarlane and Joseph Sinor collected 25 disposals each, leaving Riley Knight as the chief concern for the Eagles after he hobbled from the ground with what appeared to be an ankle ailment.
