The tradition of covering roofs with thatch continues all over the English countryside. Although most buildings are now roofed with tiles, there are still quite a few that have a covering of thatch. The thatch has to be renewed regularly, This is a lengthy and costly business that can only be carried out by the small number skilled thatchers, who operate around the country. Because of the costliness of maintaining it, having a thatched roof is now a conspicuous sign of wealth, whereas once it was not.
