Rooftec Flex EPDM Lead Replacement Flashing is a strong, flexible and lightweight alternative to traditional lead flashing, designed for a wide range of pitched and flat roofing applications.
Manufactured from EPDM with a core of expanded aluminium mesh, Rooftec Flex combines the flexibility and weather-resistant properties of EPDM with the strength and formability of aluminium. The expanded aluminium reinforcement allows the flashing to be easily shaped and dressed around roof profiles while providing excellent strength and durability.
Available in 5m and 10m roll lengths, five widths from 150mm to 600mm, and Anthracite Grey, Lead Grey or Black, Rooftec Flex provides a versatile lead replacement solution for new-build, refurbishment and roofing repair applications.
At 2.5mm thick, the material can be cut and formed on site to accommodate a wide variety of roof details.
Rooftec Flex is designed as an alternative to traditional sheet lead for suitable roofing and flashing applications.
Its construction combines:
EPDM + Expanded Aluminium Mesh
The EPDM provides a flexible external material while the internal expanded aluminium reinforcement gives the flashing additional strength and allows it to retain the shape into which it is formed.
This combination produces a durable, highly workable flashing material suitable for professional roofing applications.
At the centre of Rooftec Flex is an expanded aluminium mesh reinforcement.
The aluminium core provides additional strength while allowing the material to remain highly flexible and malleable.
This makes Rooftec Flex particularly useful when flashing needs to be formed around:
One of the main advantages of Rooftec Flex is its ability to be shaped and formed around roofing details.
The combination of flexible EPDM and expanded aluminium allows installers to dress the material closely around different profiles and junctions.
This makes it particularly useful where flashing needs to accommodate changes in shape or irregular roofing details.
Rooftec Flex provides a modern alternative to conventional lead flashing.
Unlike traditional lead, the EPDM and aluminium construction has no meaningful scrap value, helping reduce one of the common disadvantages associated with exposed lead roofing materials.
Its lightweight and flexible construction can also make the material easier to handle and work with during installation.
Rooftec Flex is available in two roll lengths:
The different lengths allow installers to select an appropriate roll for anything from smaller flashing details to larger roofing projects.
Rooftec Flex is available in:
This broad range allows the flashing width to be matched more closely to the individual roof detail.
The available length and width combinations provide the following nominal material areas:
| Roll Size | Nominal Area |
|---|---|
| 5m x 150mm | 0.75m² |
| 5m x 200mm | 1.00m² |
| 5m x 300mm | 1.50m² |
| 5m x 450mm | 2.25m² |
| 5m x 600mm | 3.00m² |
| 10m x 150mm | 1.50m² |
| 10m x 200mm | 2.00m² |
| 10m x 300mm | 3.00m² |
| 10m x 450mm | 4.50m² |
| 10m x 600mm | 6.00m² |
These figures represent nominal material area before allowing for overlaps, detailing, cutting or waste.
Rooftec Flex has an overall thickness of:
2.5mm
This combines with the reinforced EPDM and aluminium construction to provide a durable yet workable lead replacement flashing.
Rooftec Flex is available in three colours:
The different finishes allow the flashing to be coordinated with a variety of roof coverings, tiles, slates and other external building materials.
Lead Grey provides a finish suited to applications where a more traditional lead-like appearance is preferred, while Anthracite Grey and Black provide alternatives for contemporary roofing schemes.
The flexible construction makes Rooftec Flex particularly useful for pitched roof flashing details.
It can be formed around suitable tiles, slates and junctions where a flexible weatherproof flashing material is required.
Rooftec Flex can also be used for suitable flat roofing applications and associated roof details.
The material can be cut and shaped on site to suit the particular junction or penetration being weatherproofed.
Roof-to-wall abutments are a common application for flexible flashing.
Rooftec Flex can be formed to follow the roof covering and adjoining masonry, providing a lead replacement option for suitable abutment details.
The flexible EPDM and aluminium construction also makes Rooftec Flex suitable for appropriate chimney flashing applications.
Its ability to be formed around changes in profile allows installers to create detailed flashing arrangements without using traditional sheet lead.
A range of complementary Rooftec products can be used when required for particular installation details.
These include:
The accessories required will depend on the individual roof detail and installation method.
Traditional lead roofing materials can be attractive to thieves because of their scrap value.
Rooftec Flex is manufactured using EPDM and aluminium, neither of which provides the scrap value associated with traditional sheet lead.
This provides a practical advantage for suitable exposed flashing applications.
Rooftec Flex is an EPDM-based lead replacement flashing reinforced with an expanded aluminium mesh core.
The combination provides the flexibility required for forming detailed flashing while the aluminium reinforcement adds strength and helps the material retain its shape.
Rooftec Flex is manufactured from:
EPDM and expanded aluminium metal
The aluminium forms a reinforcing core within the flexible flashing material.
Rooftec Flex is:
2.5mm thick
across the available length, width and colour variations.
Rooftec Flex is available in:
Lengths
Widths
This creates a broad range of size combinations for different flashing requirements.

Where Rooftec Flex overlaps require sealing, Rooftec High Tack Polymer Adhesive is suitable for sealing the overlaps.
The same adhesive can also be used to seal Rooftec Flex to tiles, slates, brickwork and mortar.
For suitable above-ground masonry details, Rooftec Large Lead Fixing Clips can be used to secure lead alternative flashing into masonry joints.
Any additional sealing requirements should be completed according to the installation specification for the particular detail.
Rooftec Flex replaces traditional sheet lead with a combination of EPDM and expanded aluminium reinforcement.
This provides several practical differences:
The appropriate flashing material should always be selected according to the requirements of the individual roofing project.
