School roof refurbishment addresses years of water entry

By Jesse Sanchez. 

SOPREMA worked with Russell Trew Roofing to deliver a long-term roofing solution for Highfield Primary School in Staffordshire. 

Persistent leaks and an aging flat roof created ongoing maintenance challenges at Highfield Primary School in Burntwood, Staffordshire. After several years of water ingress, the school turned to SOPREMA UK for a roofing solution that could improve waterproofing, drainage and thermal performance while minimizing disruption to daily operations. 

An assessment by SOPREMA identified several issues across the existing roof, including damp insulation, standing water, building movement, low-level windows contributing to water ingress and deteriorated roof lights. SOPREMA’s technical team conducted core sample analysis and prepared a condition report, along with budget costs to support the client’s asset planning and financial forecasting. 

For the refurbishment, SOPREMA recommended its SOPRALENE 250 waterproofing system, which carries a 25-year single-point warranty and has been tested to BROOF(t4) fire classification. The project also incorporated tapered insulation to improve thermal performance and address ponding water, along with SOPREMA Draini outlets to improve rainwater drainage. 

The system design followed Safe2Torch guidance, with bespoke details developed for the building’s specific conditions. 

Approved contractor Russell Trew Roofing completed the installation with support from SOPREMA throughout the project. Because the school remained operational, deliveries and on-site activity were scheduled around the school day. Weekend work was also completed when necessary to further reduce disruption. 

The project took place during the winter months, requiring careful planning and site coordination to maintain progress. A dedicated SOPREMA field technician monitored the installation, provided on-site support and approved the completed work for warranty issuance. 

The completed refurbishment provides the school with improved waterproofing and thermal efficiency, helping create a warm, dry environment for pupils and staff throughout the year.
