Small Penetrations

Penetrations through metal roofs must:

• Be positioned at or near the high point whenever practicable
• Have “Dektites” fitted on a tray
• Incorporate a shepherd’s crooks where suitable (refer figure below).
• Only have smooth-walled conduit (flexible conduit is not permitted under any circumstances).
• Incorporate EPDM rubber grommets for copper pipe penetrations
• If a copper pipe, it must be painted over the entire exposed length
• Incorporate a shepherd’s crooks where suitable (refer figure below).
• Incorporate Red Dektites flues where heat resistant is required.
