Raising the roof

A Grade II listed residential building in Hackney has won plaudits and attracted significant praise from residents, the public and the local council’s historic building department on its successful roof refurbishment. Marley Eternit’s Acme single camber clay plain tiles were specified to ensure a striking roof for a well-loved historic local building.

The former Hackney Free & Parochial School was originally refurbished into local authority offices over a decade ago and has since undergone a second major renovation and a change of use to create East Eight, a development of 36 large residential flats. Untouched in the second renovation, the original roof that had been in place for ten years was found to be defective when leaks began to emerge and concerns were raised about the stability of the chimney stack. A detailed survey found that the entire roof needed to be replaced.

Main contractor, Anglian Brickwork Ltd and project architect, Paul Mitchell were appointed to redevelop the pitched roof, which covers a surface area of 1,500 sq/metres. During the redevelopment a combination of colours from Marley Eternit’s Acme single camber tile range was specified including 50% Red Sandfaced, 25% Heather Blend and 25% Farmhouse Brown Sandfaced.

Paul Mitchell, project architect, comments:

“As we did not want the roof to look ‘flat’ we requested samples from Marley Eternit of three colours from its traditional Acme single camber range. We felt these subtle shades provided an effective tonal blend so proposed the use of them to the historical buildings officer at Hackney local authority. Marley Eternit was able to offer comprehensive technical support throughout the project by providing advice on colour matching to achieve the final blend for this challenging roofing project. The council department is very pleased with the outcome and that the building’s traditional look has not been compromised.”

Initially, the large roof was quite deceptive due to its vast complex gables, internal gutters and no flat areas, making it a challenging process to begin with. The project was further complicated by the listed building status and torrential rain during the refurbishment process.

To minimise further disruption to residents, a rolling temporary roof, the largest in the UK at the time, was wheeled across each phase, allowing the old roof to be removed effectively in stages with minimal water ingress.

Eamon McCourt, managing agent for East Eight at Warmans Property Management, explains:

“As managers of the building, we assessed the original condition of the roof and found it had been defective since the original renovation over ten years ago.

“The choice of roof tile and gaining acceptance by the local planning authority was critical to the project, and the end result is a beautifully blended roof that remains in-keeping with local aesthetics.”
