At domestic level, he has represented Bloomfield, Nondescripts, Wayamba, Delhi Daredevils, Lancashire and Barisal Burners.Nowadays he acts as an international cricket commentator for Sri Lanka.

[15] He made his first-class debut for the club on 20 April, taking the place of injured captain and bowler Glen Chapple.

[21] Maharoof was due to leave in mid-June to participate in the inaugural season of the Sri Lanka Premier League, planning to return to Lancashire in August,[1] however the tournament was postponed until 2012.

[23] On his return to Sri Lanka, Maharoof finished as the leading run scorer in the 2011–12 Premier Limited Overs Tournament, a domestic competition.

[24] In the final Maharoof scored 52 runs while opening the batting and dismissed Sachithra Senanayake to claim his 200th wicket in list A matches.

[25] His strong performances for the Nondescripts team led to a recall to the ODI squad for the 2011–12 Commonwealth Bank Series with India and Australia.

Two players, including Maharoof, made their ODI debut in the third match of the series while three of the Sri Lankan regulars were rested.

Ahead of the tournament Chaminda Vaas, one of Sri Lanka's senior seam bowlers, sustained an injury and Maharoof was responsible for opening the bowling with Dilhara Lokuhettige.

[31] Maharoof produced one of the most economical bowling displays in ODI history,[32] conceding nine-rune from ten overs against the West Indies for which he was named Man of the Match.

[31] He was reprimanded by the International Cricket Council (ICC) for excessive appealing in the match as he began celebrating a dismissal before the batsman had been given out by the umpire.

[33] When Bangladesh toured for two Tests and three ODIs in August and September that year, Maharoof was against selected in Sri Lanka's squad, allowing senior players to be rested for some of the matches.

[35] When Sri Lanka toured Indian in October to December 2005 for three Tests and seven ODIs, Maharoof was included in the squad.

[43] After the inaugural IPL in 2008, Maharoff joined the Sri Lanka squad in preparation for the 2008 Asia Cup, however an abdominal strain prevented him from taking part.

Five players selected in the squad chose to participate in the IPL instead of Sri Lanka's first warm-up match, and consequentially Maharoof was drafted in to provide cover until they arrived.

[49] Initially called up for a single tour match, Maharoof was added to the Test squad when seam bowlers Dilhara Fernando and Nuwan Pradeep sustained injuries.

He bowls at speeds of up to 80 miles per hour (130 km/h)[31] and concentrates on accuracy rather than pace because pitches in Sri Lanka are generally slow.

[58] Under the advice of then Sri Lanka coach Tom Moody, in 2006 Maharoof altered his bowling action slightly so that his front arm was coming down straight in delivery.
