Flexible-collar flashings that seal pipe, flue and cable penetrations through a profiled roof.

Profile cross-section — schematic, not to scale

Overview

Every penetration is a hole in a roof that worked perfectly before someone put it there. These flashings use a flexible collar that seals to the pipe and a base that conforms to the profile beneath, so the detail survives both thermal movement and the vibration of a flue.

Sized by pipe diameter and available in a temperature-rated grade for flues.

Applications

  • Soil and vent pipes
  • Flues and chimneys
  • Cable and conduit entries
  • Ventilation ducts
