Product Introduction
Lightweight over-roof conversion systems were first developed in the late 1980’s and have been used extensively throughout the public and private sector as a permanent refurbishment solution for failed flat roofs.

By constructing a lightweight steel subframe over the existing roof (which is then over-clad), an effective pitch is created to facilitate water run-off.

This combined with the relocation of drainage to the outside of the building ensures water is permanently removed from a roof and the potential for any further problems eliminated. Developed by Ash & Lacy in 1991, Ashjack was the first structural lightweight overroof conversion system to be introduced in the UK. Supported by a network of experienced installers, Ashjack provides a range of systems, which can be individually tailored to suit the specific structural and design requirements of the existing building.
