CPV 4546 – Roofing Works

What does CPV 4546 cover?

CPV 4546 covers all works for the construction, renewal and refurbishment of roof structures and coverings. This includes flat roof waterproofing systems (bituminous membranes, single-ply membranes such as TPO, PVC and EPDM, liquid-applied systems), pitched roof coverings (roof tiles, flat tiles, slate, metal standing seam), dormer construction and conversion, green roof systems (extensive and intensive), solar thermal and photovoltaic roof mounting, all sheet metal work (gutters, downpipes, valley flashings, ridge cappings, window sills, eave details), as well as insulation at rafter and between-rafter level.

In the context of public procurement, roofing works are among the most technically sensitive areas of building construction. Defects in roof waterproofing and detailing can cause severe consequential damage to the building fabric and its contents. Public contracting authorities therefore typically require manufacturers' system warranties for waterproofing systems, alongside evidence of specialist installation credentials. The requirements of the applicable flat roofing guidelines (Flachdachrichtlinie) and DIN 18531 series govern the execution of flat roof works.

Contracting authorities include state building authorities, school building authorities, hospital companies and all public building owners. Comprehensive flat roof renewal programmes for existing public building stock – often involving multiple buildings – represent a major share of roofing tenders. Green roof requirements, driven by stormwater management regulations and urban cooling requirements, are becoming standard in many municipal specifications. Further information on the CPV system is available from the European Commission (SIMAP) and in Regulation (EC) No 213/2008.

Who is CPV 4546 relevant for?

Public Contracting Authorities

State building authorities, school building authorities, hospital companies and municipal housing organisations are the main contracting authorities for roofing tenders. They commission roofing works in new construction and – more frequently – as standalone renewal projects for existing flat and pitched roofs. Energy efficiency, green roof mandates and photovoltaic integration are increasingly integral to roofing specifications.

Companies and Bidders

Roofing firms and sheet metal contractors (Klempner/Dachdeckerbetriebe) are the central bidders. In addition to trade registration and references for comparable roofing projects, evidence of qualified site management (master roofer/sheet metal worker), system-specific installer certifications from waterproofing system manufacturers, and for listed building work, experience with traditional roofing materials are expected.

Information on eligibility requirements and procurement procedures is provided by the Federal Ministry for Economic Affairs and Climate Action (BMWK).
