Covering risk of lead theft
Z-Led's Aluflash, aluminium-based lead flashing alternative, enhances new properties, reduces costs and combats theft.
Barwick Developments in Leeds was finding lead being used to create scalloped canopies on new homes fronting the road was being stolen overnight.
Instead of replacing like with like, the company's sub contractor ACT Roofing suggested using Z-Led's Aluflash, aluminium-based lead flashing alternative, which was already been used for standard flashing finishing on-site.
'We were fitting the lead, coming back the next day and finding it gone! That is frustrating, and costly, as the work has to be done all over again.
The Aluflash has been left in place; whilst it looks just like lead from ground level, thieves realize as soon as they go to steal it, that it is not lead, and leave empty-handed,' said ACT Roofing director Andy Ferguson.
'Initially, we were skeptical it would work effectively in such a complex application, but have found Aluflash can be formed just as easily as lead, even to fine detailing such as creating a scalloped edge.
It is the best of all the lead alternatives because it forms so well'.
Z-Led Aluflash uses a combination of corrosion-resistant aluminium with a solvent lacquer coloured surface and self-adhesive butyl backing to create a material that provides a viable alternative to traditional, heavy lead.
It can be used wherever lead flashing would traditionally be employed- and beyond: its non-toxic construction means it is suitable for use with rainwater harvesting installations, and prevents oxidisation over time.
Z-Led has developed two unique surface finishes for Aluflash, depending on the application, but both of which are compatible with all common roof materials.
The embossed surface is designed for applications requiring less complex shapes, such as pitched roof valleys, soakers and box gutters; the unique cross-corrugated surface is designed for use where the flashing has to be moulded over and around complex shapes, and allows the Aluflash to be dressed in more than one direction.
A 100 percent recyclable polymer 'release' backing sheet helps keep the self adhesive butyl layer clean until required, ensuring a secure bond.
AluFlash is unaffected by temperature, can be laid effectively in hot or cold conditions.
The material is supplied in manageable 5m rolls, in widths from 150mm- 600mm in 50mm increments, minimising wastage and time spent cutting to fit.
It does not require specialist tools or skills to install.
The surface finish can be simply wiped clean to remove site dirt and debris such as cement mortar, and comes in a traditional 'lead grey' to compliment the building aesthetics.
In addition, Aluflash is the only material of its type to have attained an AA fire rating, enabling unrestricted use regardless of proximity of neighbouring buildings.
Aluflash is just part of Z-Led's comprehensive range of materials to defend buildings against damp and gas penetration.
Z-Led cost-saving damp-proofing solutions include Aluflash lead alternative as standard in its range of AT abutment and HT horizontal preformed trays.
New Self Adhesive Gas Resistant DPC/Membrane ensures detailing around columns and slabs is as water and soil gas proof as possible.

Use of Z-Led's MCR Preformed Multi-Crease System means effective prevention of moisture and radon ingress into larger buildings can be achieved more quickly and with less wastage.
