ROM Limited

Bauder Total Roof System (BTRS)


ROM Ltd is a specialist manufacturer of reinforcement solutions that has facilities located throughout the UK and Ireland. The waterproofing on the roof of their Sheffield manufacturing facility had exceeded its serviceable life and the main-substructure was extremely corroded leaving it unstable and requiring urgent remedial work.

Bauder Building Board

Project: ROM Ltd
Location: Sheffield
Roof Area: 9,250m²
Specifier: Mitie
Approved Contractor: Mitie Tilley Roofing

The specification

The client wanted the roof repair to cause as little impact on production levels at the facility as possible, so work on the 9,250m2 roof was split into three separate phases. The original asphalt waterproofing was replaced with the bituminous system, BTRS, which is durable, robust and can withstand permanently sited loads of up to 2000Kg/m². The system build-up also included Bauder’s 30mm PIR FA-TE insulation to achieve the required U-value.

Project challenges

One of the biggest challenges for this project was ensuring that there was no health and safety implications, especially considering the fragile state of the existing roof. To achieve this various control measures were implemented, such as installing safety netting below where the roofing works took place and managing the removal and addition of materials in a way that didn’t cause any weight loading issues. Despite the logistical challenges encountered all works were completed on time and to budget, much to the
delight of the client.

Craig Hebberd of Mitie:
“This project was by no means straight forward, however Bauder delivered expert support throughout all three phases of the work ensuring everything went as planned. The fact that the client experienced no loss in production during the refurbishment is testament to how well Bauder managed the roofing works. The client now has a high quality and visually appealing roof system that will give them confidence over its long term future performance.”
