Many roofs in Austria are covered with tiles made of baked clay. Tiled roofs have been around for thousands of years. Tiles are very long-lasting and they hold up to strong winds and heavy rains. In the Alps you can see flat stones as an outer covering on old houses, but stone is a very heavy material that needs a strong construction to support it. Wooden shingles are much lighter; they are nailed to the roof. In some areas such as England or Wales you can still find many slate roofs. They look very nice but they are fragile. You should not walk on slate-covered roofs. Another way of covering the roofs of private homes in the UK or the USA is with bitumen shingles. These come in different sizes, are very durable and are not as heavy as clay tiles. If they are big you can cover a roof with them very quickly. Another cheap and light material for covering a roof is sheet metal. 06 A2 Word bank underlying materials Unterlagematerial dormer flashing Dachgaube valley Dachkehle 07 A2 08 A2–B1 09 A2–B1 Word bank baked clay gebrannter Ton slate Schiefer fragile zerbrechlich durable haltbar, beständig sheet metal Blech Useful phrases: … have the advantage/ disadvantage that … … have one clear advantage over … There is practically no difference between … and … baked clay tiles slate-covered roof 118 Unit 22 Interaction Nur zu Prüfzwecken – Eigentum des Verlags öbv
