Sustainable Project of the Year
Protecting The Ark, Shrewsbury
Roofrite (Shropshire) Ltd. with Permavent
Roofrite (Shropshire) Ltd successfully delivered a conservation-led reroof of this vital community facility, supporting people experiencing homelessness and vulnerability, while ensuring The Ark remained fully operational, allowing essential services for vulnerable people to continue uninterrupted throughout the project.
By reclaiming existing Welsh slate, upgrading insulation and specifying Permavent APEX, the team created a breathable, weatherproof roofing system that eliminated the need for visible roof ventilation, improving energy efficiency while preserving the building’s historic character.

Best Use of Slate for a Commercial Project
The National Library of Wales
LEB Construction with Permavent
LEB Construction completed the first full reroof of the National Library of Wales in almost a century, carefully protecting more than 6.5 million books, manuscripts and nationally important archives throughout the works. Installed beneath over 2,000m² of Welsh slate, Permavent APEX provided outstanding moisture management and secondary weather protection while allowing the historic roof to breathe naturally without altering its appearance. The reroof also supported the Library’s wider decarbonisation programme, including a new 3,500m² solar PV installation.

Best Use of Slate for a Commercial Project
Halton Mills
GAP Roofing Services with Permavent
GAP Roofing Services transformed what began as a straightforward reroof into a highly complex engineering project, overcoming hidden structural defects, challenging roof geometry and failed ventilation systems without compromising quality or programme.
Originally planned as a repair project, the scheme quickly evolved into a full reroof after years of hidden deterioration were uncovered.
A fully integrated Permavent roofing system, including DRY+, Easy Slate, Universal Ridge & Ventilation Systems and Permatac® Butyl Tape, delivered a robust, breathable roofing solution backed by a 40-year warranty, providing long-term protection for residents and the building alike.
