As Copper Roofing Ecclesiastical Heritage Work Specialists, we were asked to replace a section of the roof at Southwark Cathedral. A great many churches will choose copper as a roofing material, not only fit with existing and where there are Grade I or II requirements to do so, but because Copper Roofing has an exceptionally long life with practically no maintenance required.
Where copper roofing is the preferred choice, the majority of churches will also normally opt for the natural bright copper when carrying out ecclesiastical heritage work, rather than the pre-patinated (already green), as it is the most economical of the two options.
That was the case on the Copper Roofing of Southwark Cathedral, where they were replacing only part of one of its many roofs. The work was carried out in the traditional style and the original old copper was 100% recycled.
The sheer size of most church roofs is another reason why you will see many of them created in copper roofing, because a copper roof is half the weight of a lead and quarter the weight of roofing tiles, thus lessening the weight on the foundation of the church and the roof structure.
