• Removal, disposal and replacement of existing cover caps and pressure plates.
• Installation of new system pressure plate gasketry.
• Installation of butyl glazing tape underneath pressure plates.
• Replacement of defective silicon butt seals.
• Installation of new EDPM vapour barrier at the heading of glazing system interface with new vertical glazing.
• Installation of new EDPM vapour barrier at eaves flashing level.
• Installation of new flashing at the heading of glazing system interface with new vertical glazing.
