A hemming tool is used to hem a roofing panel having a base portion, a pair of standing ribs extending in a longitudinal direction along opposing sides of the base portion, and a tongue section extending from the base portion beyond the standing ribs, for use in a standing seam roofing system. The hemming tool comprises a panel support supporting to roof panel thereon such that the tongue section extends outward beyond a free edge of the panel support. A die member having a working surface, for engaging the tongue section of the roofing panel, is supported by a die support linkage such that the working surface of the die member is arranged for rolling engagement with the tongue section of the roofing panel about the free edge of the panel support from an upper surface to a lower surface of the panel support.
