Aztec Master Flashing MAXI – EPDM Roof Pipe Flashing 304 – 724mm

Aztec Master Flashing – EPDM Roof Pipe Flashing 304–724mm (864x864mm base)

Engineered for very large penetrations, this flashing suits 304–724mm pipe diameters and features an 864x864mm base for maximum coverage and stability.

The Aztec Master Flashing (EPDM) is a high-quality, flexible roof flashing designed to create a weathertight seal around pipe penetrations on a wide range of roof types. Suitable for metal roofing, slate roofs, tile roofs, and profiled sheets, this flashing provides a reliable, long-lasting seal for both new installations and retrofit projects.

Manufactured from durable black EPDM rubber with an aluminium base, the Aztec Master Flash is built to withstand UV exposure, extreme temperatures, and natural roof movement without cracking, splitting, or perishing over time.

Where Is It Used?

EPDM pipe flashing is commonly used to seal around:

• Ventilation ducting
• Flue pipes and stove pipes
• Soil vent pipes
• Solar panel pipework
• Extraction systems
• General roof penetrations

What Makes EPDM Master Flash Effective?

Unlike rigid flashings, the Aztec Master Flash features a flexible cone design that allows it to adapt to different pipe sizes and roof profiles. The aluminium base can be shaped to suit corrugated or uneven roof surfaces, ensuring a tight seal.

Each unit is supplied with clearly marked cutting rings, allowing the flashing to be trimmed on-site for a precise fit around the pipe diameter.
