Roof Refurbishment for Welsh Water, Cleppa Park Delivered with Gemello® Revive

Overview

At Cleppa Park in Newport, Welsh Water undertook a 2,500m² roof refurbishment to address severe deterioration of the existing composite roof. Water ingress, coating delamination, and ageing rooflights posed ongoing risks to performance and durability. With live site operations to consider, Welsh Water needed a robust solution that could be delivered with minimal disruption.

The Challenge

The project demanded complex coordination, including safe removal and reinstatement of PV panels, redesign of rooflight structures, and phased works to keep the site operational. Delivering enhanced thermal efficiency and long-term weatherproofing under such constraints required a system proven for speed and resilience.

The Solution

Welsh Water selected Gemello® Revive, SIG Building Solutions’ prefabricated roof and wall over-clad system. Gemello® Revive’s over-clad design enabled a fast and reliable refurbishment with minimal interference on site. Panels were efficiently installed to provide a secure, thermally efficient envelope backed by a 25-year warranty, ensuring Welsh Water could continue operations with confidence.
