CHOICE FOR TYPE OF ROOF CONSTRUCTION

The supporting structure of a flat roof is of key importance. This can be decisive in the choice and method of attachment of a Hertalan EPDM roofing system.

Both the design of a roof construction and the installation of a roofing system must meet strict requirements in the UK. These requirements are partly influenced by the market and partly by Building Regulations.

ROOFING SYSTEMS

During the determination of the design it is important to know what EPDM systems are suitable to use. For this we have created a document which you can download here. Below we provide a list of appropriate systems.

EPDM roofing system: Mechanically fixed
