The municipality lies on the Lützelsoon, a plateau forming part of the Hunsrück, roughly 6 km south of Kirchberg.

In the former document, Count Emich of Sponheim, Archdeacon of the Diocese of Liège and titular parish priest at Kirchberg, endowed benefices in ten villages to maintain chaplains.

In the latter document, Johann of Dhaun transferred to the Knight of Sötern a waldgravial fief, the so-called Torsengut (a circular or elliptical shape) of Rohrbach.

Nonetheless, this ended when the House of Sponheim died out in 1437 and the village passed to the Counts of Veldenz and the Margraves of Baden.

About 1600, the southern part of Rohrbach belonged, along with six Hintersassen (roughly, “dependent peasants”) to the “Further” County of Sponheim and, locally, to the Amt of Dill, while the northern part belonged to the Badish Oberamt of Kirchberg; the boundary between these two territories was the village's namesake brook itself, the Rohrbach.

In the course of administrative restructuring in Rhineland-Palatinate, various former Ämter were merged in 1971, and Rohrbach, along with the Amt of Gemünden, was assigned to the Verbandsgemeinde of Kirchberg.

Catholics, who make up about one fifth of the population, have the right to celebrate Mass at the Evangelical church, which they do especially when there is a funeral or wedding ceremony to be performed.

The composition on the dexter (armsbearer's right, viewer's left) side is the arms formerly borne by the Margraviate of Baden, a former landholder in Rohrbach.

The composition on the sinister (armsbearer's left, viewer's right) side is canting for the municipality's name, “Rohrbach”, which literally means “Reedbrook”.

The following are listed buildings or sites in Rhineland-Palatinate’s Directory of Cultural Monuments:[4] Four clubs involve themselves in village life: the Evangelical Women's Aid (Evangelische Frauenhilfe in Deutschland), a music club, the Countrywomen's Association (Deutscher Landfrauenverband) and the fire brigade.
