In 1417, the village passed along with the Amt of Kastellaun to the “Hinder” County of Sponheim.

The municipality's arms might in English heraldic language be described thus: Tierced in mantle, dexter chequy gules and argent, sinister argent a fleur-de-lis azure, and in base vert a plough of the second.

The charge on the sinister (armsbearer's left, viewer's right) side, the blue fleur-de-lis on the silver field, refers to Roth's first documentary mention in an 1100 directory of holdings from the Karden Foundation.

The red and silver “chequy” pattern on the dexter (armsbearer's right, viewer's left) side is a reference to the village's former allegiance to the “Hinder” County of Sponheim.

The silver plough on the green field refers not only to the great importance and tradition of agriculture in the municipality, but also to the origin of the village's name (“Roth” comes from the same root as the German verb roden, meaning “clear”, with reference to clearing land of trees for farming and settling).
