Description
The Master Flash Multi-Flash is a two-in-one roof flashing. Left whole it installs exactly like a standard Master Flash; cut open along the marked lines it becomes a retrofit flashing that wraps around existing pipework without disconnection, locked with the included stainless-steel gripper strip. This size covers pipe diameters of 171mm to 343mm.
The Master Flash Standard is a flexible cone roof flashing that seals ducts, pipes, flues and vents where they pass through the roof. The square base carries an embedded aluminium band that moulds down onto profiled metal, tile and membrane roofs by hand, forming a lasting watertight seal without specialist tools, and the cone trims to the pipe size against clearly marked steps.
Made from premium EPDM rubber, it resists UV, ozone and weathering, staying flexible from -55°C up to +100°C continuous (+135°C intermittent) — ideal for ventilation ducting, soil stacks and extract terminals.
