It sits in a slight hollow rather than on an exposed crest, which is an unusual placement for a standing stone; these monuments, erected across Ireland from the Neolithic through the Bronze Age, are more commonly associated with prominent, visible positions in the landscape. The stone measures 1.4 metres by 1.1 metres and is orientated along an east-west axis, a detail that may or may not be coincidental, given how frequently prehistoric monuments show some alignment with solar or lunar events.

What makes the Roolagh stone particularly interesting is that it does not stand alone. A second standing stone lies to the southwest, close enough that the two were almost certainly considered together by whoever raised them. Paired or grouped standing stones are known elsewhere in Ireland, and while their precise function remains uncertain, they are generally understood as markers, whether of boundaries, routeways, burial sites, or ceremonial spaces. The west-facing slope the ridge overlooks would have been visible from both stones, suggesting the broader landscape played some role in their siting. The limestone from which the Roolagh stone is made is the local bedrock across much of Tipperary, so the builders were almost certainly working with material close to hand rather than transporting it over any great distance.
