The dimensions of the chapel of Saint-André d’Andlau are unconventional. Classified as a chapel because there is an abbey in the village, it is as large as a church, with nearly 900 m² of roof in need of renovation. Although the original building dates back to the medieval Carolingian period, the chapel has been expanded and restored several times. Today, its octagonal tower keeps watch over an old cemetery on the edge of vineyards.
COMBINING INNOVATION WITH TRADITION
The historic site was the perfect place to use traditional clay tiles of high quality. Two versions of the natural coloured tiles, scallop and bullnose, were selected to ensure a perfect fit. The production is complex as the tiles are slow baked for five days in a furnace at a high temperature to ensure flexibility during production. Shaping and cutting of all extra parts is entirely carried out by hand. The experienced roofer Aimé Fluck and the mayor of Andlau chose the colours Noir de Vigne (Vine Black) and Rouge de Mars (Mars Red), which are colours that occur frequently in the local area.
Very special attention was paid to the combination of tiles used on the roof: an area of 3 m² was tiled to find the right proportions of red and black tiles, in scallop and bullnose styles. The aim was “to recreate the slight irregularities that can be seen on old roofs with a blurring of lines”. Red and black were alternated “to preserve the aged look of a red roof mottled with black, a sign of natural ageing in terracotta tiles”. It was important that the renovation of the chapel roof should preserve the authenticity of the building by retaining the aged look that is part of historic buildings and a characteristic of the regional heritage.
