Thatched-roof houses



THATCHED ROOF:

  • Thatching is the craft of covering a roof with dry vegetation such as straw, water reed, sedge, rushes and heather, layering the vegetation so as to shed water away from the inner roof. It is probably the oldest roofing material and has been used in both tropical and temperate climates. Thatch is still employed by builders in developing countries, usually with low-cost, local vegetation. By contrast in some developed countries it is now the choice of well-to-do people who want their home to have a rustic look.

History

The tradition of thatching has been passed down from generation to generation for thousands of years.

Records of European thatch date back to before the Middle Ages, when the first villages were established. The creation of villages brought with it the need for readily available, inexpensive, and durable building material, such as thatch. “Thatch houses built in close proximity helped to account for the frequent and disastrous fires that swept through the narrow streets of medieval cities. Eventually the authorities wrote the Ordinance of 1212, arguably the first building regulation in force in London, prohibiting the building of new thatch roofs and demanding the whitewashing of existing ones with plaster daub.

Technology in the farming industry has had a negative impact on the popularity of thatching. Use of the material declined following the First World War in particular, and with the invention of the combine harvester and the need to develop shorter stemmed varieties of wheat, the long straw once produced was no longer available. The increased loss of water plants and wildlife occurred with the shift from open ponds to cattle troughs and piped water for animals. With it came the decline in availability of rushes, and other wetland vegetation used in thatching.
