R-MER LOC standing seam aluminium system colour matched to existing oxidised copper profile

The use of copper within construction is unmistakable due to the unique colour it inherits as a result of oxidation. Its warmth and beauty make it a preferred material for many architects. Unfortunately, due to the methods in which these systems were initially installed, weakness can develop and we are seeing an increasing number of failures nationwide including here at Compton School in London. Constructed over 50 years ago, the condition of the copper roofing systems were rapidly deteriorating and starting to show water ingress.

This ingress of water had led to damage to the asbestos insulating board (AIB) which had been installed at the time of construction, well before the associated health issues were known. This ingress to the AIB was a result of failure to the fragile fibreboard decking which if not address could have led to collapse and subsequent closure of the teaching areas. As a result of these findings it was decided that the existing asbestos would have to be removed, along with the failing deck as a priority with the roof system replacement to follow.

Funding for this project was secured as part of the governments Condition Improvement Fund (CIF) which seeks to address significant building condition needs in teaching environments. In this case the bid was secured due to the high potential risk to health and safety which is considered to be of the highest priority to the goals of the funding.

The Garland Technical Manager suggested rather than replacing like-for-like with a copper system, which would be extremely expensive and complicated to install, that Garland’s R-MER LOC standing seam metal system would be the best solution. Fortunately some profiles were found to be in a stable condition. As a result it was essential that the new system matched the aesthetics of the green copper patina. The R-MER LOC standing seam system is available in a wide range of colours and textures, making it the ideal choice.

To ensure the new roof remained watertight for the design life of the system, a ply deck was installed, above which a new layer of rock wool insulation was installed. This not only met the current L2B regulations but also saved around 20% in energy costs due to the reduction of heat lost through the roof.

The partnership between client, contractor and manufacturer ensured the project was delivered on time and on budget whilst providing the school with a guarantee up to 30 years.
