Pullman London , St Pancras – Roof Replacement

The Pullman London St Pancras hotel is situated centrally between London ’ s extremely busy Euston , St Pancras and Kings Cross stations , with the constant traffic of the Euston Road running directly outside the front of the property . Rising up to its full height in excess of 17-storeys , the Pullman hotel is a modern example of the city ’ s eclectic mix of buildings and overlooks many of the local properties .
Project description
At 17-storeys tall , The Pullman London St Pancras , is one of the many iconic properties within the AccorInvest portfolio . A luxury hotel that dominates the skyline and overlooks all of the buildings around it , the views from the upper roofs are unrivalled in that area of London .
As part of our multi-service and growing relationship with the client , our unique and holistic approach to the building envelope has aligned with the client ’ s over the last decade , helping them to maximise ROI across the portfolio . Through this holistic and allencompassing approach we were asked to support the client through the replacement of their leaking and failing roofs , from the initial inception , core sampling and specification development , through to the delivery of the works .
With a multitude of individual buildings making up the overall hotel and all interconnected , each of the individual roofs had been repaired and maintained over the years , extending their lifespan and helping to prolong the need for replacement ; however some of the roofs had finally reached the point where repairs and patching were no longer a viable or cost effective option , with the replacement of each roof providing the best solution for the future .
Project overview
Situated in close proximity to London ’ s main train stations , and with the iconic attractions of the British Museum , British Library and all of London on its doorstep , the hotel is an ideal location for travellers wishing to see the London sights .
Originally built for the council in 1971 and re-purposed over the years , in 2005 it was transformed into the Pullman St Pancras and now takes its current form as a 17-storey modern hotel . Over the years , the roofs of the hotel have been replaced , repaired and have been found to leak , being a constant thorn in the hotel ’ s side and a nuisance for the hard-working maintenance team .
With the main roof of the 17-storey tower block having had quick fixes and repairs over the years , the leaks were becoming unsustainable and the roof had gone past its originally intended lifespan . The onsite team had been able to avoid the need for replacement by undertaking the repairs , but this was no longer viable and a long-term solution was needed .
Over time and multiple leak detection surveys , we had been able to support the client and identify the issues that were leading to the water ingress , which just increased as each year passed . Amongst these issues were cracks in the lead work , defects to the masonry including missing pointing and delaminating render , degraded materials surrounding the roof system and the major issues being the cracking , shrinkage and general failure of the current coating system .
In order to ensure that the correct specification and materials were utilised , providing the client and property with the most appropriate , longterm and future-proofed solution for the new roof , the initial stage of the project saw further inspections , testing and core samples carried out . Through adherence and crosshatch testing , we were able to provide the client with a range of specialist products that would achieve their goal of waterproofing the roof areas , but also provide a warranty that aligns with their future needs .
