== History == The company was founded in 1947 by Heinrich Roth as a craft business (manufacturing wash boiler stoves and garden slab plates).<ref>''Das Unternehmen: Roth Umwelttechnik GmbH''.

Jubiläum. |work=Sanitär + Heizungstechnik |pages=59–61 |language=de}}</ref> Under Manfred Roth (1939–2025), the founder's son, the company developed into an internationally active group of companies with locations in Europe, North and South America and China from 1962 onwards.<ref name=":0" /> In addition, the company expanded its business activities in the 1960s under Manfred Roth's leadership into the field of heating and sanitary technology,<ref name=":0" /> producing, for example, heating oil tanks.<ref name=":1">Hartmut Bünger: ''Vom Kesselofen zum Komplettsystem''. In: ''Hinterländer Anzeiger'' {{in lang |de}}. 2 February 2023.</ref>
Due to the susceptibility of steel tanks to corrosion when storing heating oil, the company decided to enter the field of plastics technology (large blow-molding technology for storage systems for fuels and biofuels) in 1970.<ref name=":0" /><ref name=":1" /> Roth Industries also expanded the sanitary segment with the development of complete shower cabins.<ref name=":1" /> In 1977, the company Schlesinger, a manufacturer of machinery for brush and broom production, was integrated into the group.<ref name="ReferenceA">''Maschinen für Bürsten in aller Welt''. In: ''Oberhessische Presse'' {{in lang |de}}. 8 October 2019.</ref> The following year, the Roth Werke GmbH was founded.<ref name=":5" />
In the 1980s, the company began offering energy systems such as underfloor heating systems. In 1989, Roth Industries acquired Bolenz & Schäfer, a company active in the fields of hydraulics and filament winding,<ref name=":1" /> as well as the company EHA, which was active in special-purpose machinery for coating and impregnation processes involving web-based materials.<ref name=":2">{{Cite news |date=2023-12-20 |title=Roth Hydraulics feiert 80-jähriges Bestehen |work=Hinterländer Anzeiger |language=de}}</ref>

In: ''Sächsische Zeitung'' {{in lang |de}}. 12 November 2005.</ref> At the end of the 1990s, the market for oil tanks collapsed, prompting restructuring measures within the company. For example, the sites in the east of Saxony, in operation since the early 1990s, were converted to the production of environmental technology (such as rainwater and wastewater systems) for industrial and agricultural applications.<ref>Miriam Schönbach: ''Großer Erfolg mit großen Tanks''.
