BriefAs part of the drive to revitalise Kirkby Town Centre, the local authority, Knowsley Metropolitan Borough Council, has been significantly investing in regeneration works. A redundant B&M shopping centre formed an important part of the uplift.At 36,000 sq ft, the empty precinct was the largest vacant unit in the town centre and was in need of significant repair and modernisation. Bringing the building up to date was crucial in encouraging businesses back to the area and delivering more choice of retail outlets to visitors.The project was estimated to cost £1.66million, with £450,000 allocated to the roof renovation, which was to be carried out by Paramount Roofing Systems, in association with IKO.ChallengesThe busy, central location of the shopping centre presented several challenges for the roof installation. The existing roof needed a comprehensive refurbishment, including stripping back to the metal decking and removal of all layers and outdated materials.A total of 48 redundant skylights needed to be carefully and meticulously taken out as they were no longer needed or functional. Any obsolete ventilation fans and plant equipment also had to be removed, as streamlining roof space was essential for efficiency. This all had to take place before the installation commenced.When it came to delivery of materials, there was limited laydown due to the surrounding live loading bays for neighbouring shops and this lack of space also affected the storage of the materials on-site.Inclement weather presented a significant challenge for the team. Despite operations taking place during the summer, torrential downpours were frequent. Protecting the integrity of the building was paramount to ensure the businesses below the installation could continue trading without risk of water ingress or leaks.SolutionAs this was such an expansive project, it was important that the roofing system was robust, easy to install and would stand the test of time. IKO worked with Paramount Roofing Systems to ensure the most suitable solution was specified for the replacement roof.A fully built-up bituminous felt warm roof was chosen as the best option, as it was designed to ensure effective insulation, weatherproofing and longevity for many years to come.To mitigate disruption to nearby trade, Paramount Roofing Systems effectively coordinated with local businesses for the duration of the project. The team established a robust schedule, so that construction activity was minimally affected by the town centre’s busy hours and zoned time restrictions.A telescopic forklift truck was hired specifically for the project, to handle offloading and loading more efficiently and allow the team to move more precisely within the confined space. Four operatives were trained to ensure that the forklift truck was used safely, which was imperative given the high footfall close to the site.IKO arranged for bulk materials to be delivered directly to the roof to help overcome the issue of restricted space. Materials were also stored off-ground and covered at all times with strategically placed tarpaulins to avoid water damage from the persistent rain.Despite the wet weather conditions hindering progress, the project was delivered just over the expected time frame of 8-10 weeks. The collaboration between IKO and Paramount Roofing Systems was pivotal in ensuring that the project met and exceeded requirements – contributing to an integral building that promises to give a much-needed boost to Kirkby town centre.

Project descriptionDixons Academies Trust is a well-established multi-academy trust that aims to challenge educational and social disadvantage in Yorkshire and the North West.The trust transforms schools into safe and high-performing learning environments, enabling students from all backgrounds to realise their potential and maximise their opportunities after school.Alpha Roofing Systems was brought in to refurbish two roof areas at Dixons Croxteth Academy in Liverpool after the existing waterproofing failed.A number of complex challenges arose from the start; after stripping back the aged and failed single ply system, Alpha identified a water-saturated bituminous roof beneath, which also overlaid the original asphalt waterproofing.The excess weight imposed on the roof from the multiple, heavily saturated waterproofing systems led to cracking and depressions in the deck, as well as rusting of reinforcement within the structure.This meant that, before installation work could even begin, many hours of labour were required to remove the top two waterproofing layers to expose the original asphalt. What’s more, this work had to be undertaken both during term time and a period of heavy rainfall.Solution and installationAfter close consultation with their IKO business manager, Mark Taylor, the Alpha team selected the IKO ULTRA Prevent 25 waterproofing system for this project.To adhere to Department of Education requirements, a 35-year durability statement was necessary, so the long-lasting, durable finish offered by the IKO ULTRA Prevent system was ideal.Challenges continued to come thick and fast throughout the project; after stripping the roof back to the asphalt waterproofing, a large expansion joint was found near the clerestory window. Tapered designs were subsequently adjusted to accommodate.30 tonnes of waste material – primarily due to the uplift of the previous failed waterproofing systems – also had to be removed from the roof over the course of a week.Furthermore, complex design variables meant that Alpha could not fully determine the existing roof falls until the roof had been sufficiently exposed. Working closely with the IKO technical team, design information and solutions were identified to keep the project on track.To complicate matters further, Alpha was also required to carry out this extensive work during active teaching time. This presented not only additional health & safety considerations but also the need to minimise disruption.With a stringent construction phase plan and regular active monitoring, the project was completed with a zero incident/accident rate and excellent feedback from the client on Alpha’s approach to safety.Despite a number of hurdles and complexities to overcome, Alpha Roofing Systems delivered the project ahead of time and within budget, providing a low maintenance, long-lasting roof for Dixons Croxteth Academy and a satisfying outcome for all involved.
