Résumé en anglais
From the early medieval period and well into the nineteenth century, shingles were one of the main roofin materials used for prominet buildings in Swedish churches and belfries, castles and manor houses. Since the manufacture, laying and maintenance of roof shingles are typical craft occupations, shingles, which used to be the cheapest of lasting materials, have now become the most expensive form of roofing, with the natural result that the number of shingled roofs have been steadily declining for a long time.
