Windies beat New Zealand to win Test series
Resuming on 135-4 at Sabina Park, the hosts comfortably reached their target 40 minutes before lunch, finishing on 206-5.
Roach led the way with his no-nonsense approach, spanking four boundaries in a career-best innings that spanned 60 balls and 80 minutes.
West Indies won the two-match series 2-0 to follow successes against New Zealand in Twenty20 matches (2-0) and one-day internationals (4-1).
New Zealand's only success came through off-spinner Kane Williamson, who removed Roach with just 23 needed. Roach slashed to backward point where Tim Southee pouched an easy catch.
Chanderpaul, who moved his career Test average to 50.20, and Roach shared a 70-run fourth-wicket partnership after coming together on Saturday at a nervous time for the West Indies on 113-4.
Guyanese left-handers Narsingh Deonarine and Chanderpaul led West Indies to victory. Deonarine lashed two fours in an unbeaten 15 before Chanderpaul struck the winning single with a glance off the back foot against Williamson.
Marlon Samuels was man-of-the-match for a dazzling 123 in the first innings and a valuable 52 in the second. Roach, who took 12 wickets in the two Tests at an average of 18.25, was man-of-the-series.
