Roscommon were dispatched in comfortable fashion on Saturday.
Laois have progressed to the All Ireland Junior Camogie semi-finals after topping their group with a perfect record.
The O'Moore County collected their fourth win from four outings with a convincing 4-13 to 2-9 victory over Roscommon in Mountrath.
The game was tied at half time 1-5 to 2-2, however Laois emphatically won the second half thanks to goals from Aimee Collier, Ava Coss, and Rachel Deegan.
Pat Collier and Robert Jones' side now have a three week break while the All Ireland quarter finals are run off.
The All Ireland semi-finals throw in on July 20th at Donaghmore Ashbourne GAA.
