National roofing and waterproofing experts, Langley Waterproofing Systems Ltd, has helped London’s largest high school, and third largest in the UK, Kingsbury High School, refurbish its roof ensuring it meets the highest standards.
Kingsbury High School approached specialist consultants, Capital Property and Construction Consultants (Capital PCC), to refurbish its facilities and help provide greater efficiency and all-weather proof systems within its buildings. Capital PCC called upon Langley to carry out a complete survey of the school’s existing 9,000m² roof system.
Langley compiled an in-depth report document detailing the findings and made recommendations for improvement works. The report allowed Langley to identify solutions to ensure the school was compliant with building regulations, and highlighted complications with the schools current roof drainage system which required a full redesign of each roof area.
Problems with the existing roof included ineffective insulation, defects in asphalt surfaces and cracks and interlayer blistering. Evidence of a long history of waterproofing issues was also found across the roofs due to issues with the drainage system and drainage patterns of the roof which caused flooding during heavy rainfall.
Split into two areas – Bacon Lane and Princes Lane – Langley worked closely with Capital PCC and Langley approved contractors, 
Breyer Roofing to complete the first phase of the project on the Bacon Lane premise – an area totalling 6,000m². The roof’s unusual architectural design, which included a central block with two curved wings coming forward, meant that every roof had to be individually designed due to the variation between the different roofs and drainage issues each roof presented.
Langley’s technical team were on hand to deliver support and advice throughout the project, including weekly site monitoring and regular meetings, resulting in a roof that has enabled the school to retain more heat, thanks to improved insulation.
Luke Vivian, Chartered Surveyor and Associate of Capital PCC, said: “When the project was brought to our attention, we contacted Langley as we knew we could depend on their guidance and technical assistance. Langley were able to calculate the best solutions thanks to the survey they carried out, which included detailed design of the tapered insulation
to the flat roofing.
“The technical after-sales support Langley provided, which includes inspections and roof guarantees, ensured that the project ran smoothly. We are pleased with how the project has been delivered and we have also received fantastic feedback from the school.”
With the first phase of the project complete, work on the second phase could finish by October 2015, if the school’s application for funding is successful. Tim Gardner, Area Manager at Langley, said: “This was a challenging project to be involved in due to the size and scale of the existing roofs and the timeframes given by the school.
“After working closely with both Capital PCC and Breyer Roofing, we are delighted with the ongoing results. The feedback we have received from the school has been excellent and we’re now looking forward to completing the project once the second phase can commence.”
