Ash & Lacy Covid-19 Measures

We have begun a phased return to normal operation, supporting the increasing number of customer sites and plants that are now opening. Our West Bromwich and Smethwick locations are largely operating as normal with continued support from home workers. We anticipate opening our remaining facilities over the next few weeks as demand dictates. We apologise for any disruption you may have experienced.


The AshJack over-roofing conversion system has been the choice option for two decades. Progressive system innovation has ensured that it remains undefeated, providing a new and enhanced lease of life for the widest possible range of failed flat roofs, in both the public and private sectors.

BBA-Certified AshJack is the ideal flat-to-pitch solar conversion system and can form a perfect stand alone solar array support system on solar farms – the most economical way to “go green” and reduce energy costs, while the existing flat roof remains in situ. The additional insulation layer(s) that AshJack facilitates make a valuable further contribution to energy savings.

Lightweight flat-to-pitch 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 flat-to-pitch over-roof 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.
