Flashing Overtile 1.8X 225 X.4

The Overtile Flashing 1.8m x 225mm x 0.4mm is a roofing flashing designed to help protect roof junctions and vulnerable areas against water penetration. Measuring 1.8 metres long, 225mm wide, and 0.4mm thick, it provides a practical solution for directing rainwater away from roof joints and helping create a weather-resistant roofing installation.

Overtile flashing is installed over the roofing material at specified junctions, helping prevent rainwater from entering gaps between the roof and adjoining walls or structures. It is suitable for new roofing installations, renovations, extensions, and roof maintenance projects.

Overtile Flashing for Roof Waterproofing

The Overtile Flashing 1.8m x 225mm x 0.4mm is designed to form a protective barrier over vulnerable roof junctions. Correctly installed flashing helps guide water over the roofing surface rather than allowing it to penetrate beneath the roof covering.

The 225mm width provides useful coverage across the flashing area, while the 1.8m length makes it practical for standard roofing installations. The 0.4mm thickness provides a workable profile that can be positioned and installed according to the roofing requirements.

Why Use Overtile Flashing?

Roof junctions are particularly vulnerable to water penetration if they are not correctly sealed and flashed. Overtile flashing provides an additional layer of protection by covering these areas and directing rainwater towards the roof drainage path.

Correct flashing installation can help reduce the risk of leaks, moisture damage, deterioration of roof components, and water entering the building.

Installation Guidelines

Ensure the roof surface and adjoining areas are clean and correctly prepared before installing the flashing. Position the overtile flashing so that it provides adequate overlap with the roofing material and directs water away from the junction.

Secure the flashing using appropriate roofing fasteners and sealing products according to the roofing system being used.

All overlaps, joints, and fixing points should be correctly sealed where required. For critical waterproofing applications, installation should follow the roofing manufacturer’s specifications and applicable building requirements.

Storage and Handling

Store the flashing in a clean and dry location before installation. Keep it flat and protected from bending, denting, or other physical damage.

Sheet-metal edges may be sharp. Wear suitable protective gloves when cutting, positioning, and installing the flashing.
