Mansion House is a five-storey office building located in Altrincham in Trafford, Greater Manchester. Built in the 1980s, its roof required a replacement as the covering had reached its end of life and, as a result, had started to cause various issues, including water ingress.
Hantall Developments instructed Allied Roofing to deliver the project and enhance the roof’s durability and longevity.
Workmanship
While the roof had reached its end of life, the slates originally used are a high quality, robust and lightweight product and most suitable for the job. For this reason, we specified a like-for-like replacement, which ensured the appearance of the roof was in keeping with its original style, while upgrading the specification and installation to the current manufacturer and British standards to provide longevity. After removing the existing slate tiles, we installed new blue/black Cedral Etex NT Thrutone fibre cement slates.
Fibre cement slates are a cheaper alternative to natural slates, but still give the same professional, aesthetically pleasing appearance. Despite them being made from an incredibly hard-wearing, reliable material, they are one of the lightest options available. This made them the perfect choice for Mansion House’s roofing system.
We then mechanically fixed the ridge and hip tiles in a dry-fix, maintenance-free system to provide ventilation and protect against stormy conditions without the need of regular upkeep to the ridge/hip system. To ensure that the new roof system complied with current requirements, we also installed a full eaves ventilation system.
Project challenges
Due to the height of the building, we had to carefully manage the loading of materials and the removal of waste. We had to adapt our usual process by integrating a purpose-made hoist with the scaffolding.
The building was fully operational throughout the project, with office workers and visitors coming and going daily. We took this into consideration with our risk assessment and safety management plan to ensure the safety of our operatives and the building’s occupants, as well as to minimise disruption for the utmost convenience. We paid particular attention to scaffolding requirements, in terms of providing uninterrupted access to the building and preventing unauthorised access to the work area. All walkways at the front of the building were kept clear for safe and convenient access.
Result
Despite facing numerous challenges, we completed the project on time and within the agreed budget. The client was delighted with the results – they now have an aesthetically pleasing roof that will last for decades.
“Allied Roofing have recently completed a commercial re-roofing project for us, with great success. This was a particularly challenging site due to the ongoing use of the busy existing office block. Allied not only completed the works on time and to a good standard, but also worked with us to ensure our client and the building tenants were looked after, and disruption was minimised. We were very happy with the end-product and, most importantly, the client was too!”
