Metal Roof Master Flash Range

Easy Install & Weather Resistant

The Metal Roof Master Flash® range is made from weather resistant EPDM compound or high-temperature silicone. The aluminium insert for fastening to the metal roof makes it an easy installation for most metal roof profiles. The Roof Pipe Flashings are compounded specifically for maximum resistance to weathering from ozone and ultraviolet light.

Master Flash Tile Range:

Malleable for any Installation

The Master Flash® Tile Flash range has been specifically designed for applications for roof penetrations on tiled roofs. Aztec Flashings options for tiled roofs are lead and aluminium based and are designed to suit most tiled roof profiles. 

Our lead-based products are far more malleable for tiled roofs with increased profile obstructions. The rubber roof boot is bonded to the material base and is made of EPDM rubber. For hotter applications, such as a wood heater installation, a silicone compound is advised as it will take temperatures to 250 degrees celsius.

  • One-piece Construction – allows for easy on-site installation
