ROOFING SYSTEMS
Independent certification For any roof system that is proposed as part of a specification, it is important to review the system information to ensure that the solution fully complies with the regulations. The first, and often most important, source of information is the details published by the system supplier. This should outline the system and its components as part of its build-up. This can further be verified by a manufacturer or supplier’s investment in extensive testing and gaining independent certification, that will confirm its compliance, and other relevant performance data, such as durability. For example, British Board of Agrément (BBA) certification will confirm compliance with the relevant Building Regulations, including whether it has Broof (t4) classification. Other forms of independent verification include certification from an independent fire testing organisation, which will confirm the system’s classification, but will not detail other performance data.
Compliant installations
Finally, it is essential to ensure that once the suitability and compliance of the selected system has been confirmed, it is installed and maintained correctly, as this can affect its performance in the event of a fire.

installed by a contractor that is trained to do so. Often, leading system suppliers will have a database of approved contractors who are certified to install the system. It is also advisable to select a supplier that monitors the work throughout to ensure that the roofing system is installed in the correct configuration, fully in accord with the specification, and with all the specified components.
For healthcare estates teams, fire safety is among the most important considerations, and the correct specification of flat roof systems can help to maximise a healthcare building’s resistance to fire. However, to do this effectively, decision-makers should ensure that they choose an asset management partner that collates data via roof condition surveys to allow proactive planning of refurbishment of roof areas
as required, specification collation, design, and installation. This can effectively mitigate fire risks across the building estate, and ensure peace of mind for decision-makers that they are choosing a risk-free partnership with a single source of accountability.
