Thatching is the craft of building a roof with dry vegetation such as straw, water reed, sedge, rushes, heather, or palm branches, layering the vegetation so as to shed water away from the inner roof.
Statistically, homes with thatched roofs are no more likely to catch fire than those with conventional roofs, however if they do the results are often rapid and spectacular. It seems worse, mainly because thatched fires in unprotected properties usually causes severe damage and therefore receives maximum publicity.
Thatch is also a natural insulator, and air pockets within straw thatch insulate a building in both warm and cold weather. A thatched roof ensures that a building is cool in summer and warm in winter. Thatch also has very good resistance to wind damage when applied correctly.
The lifespan of a thatched roof is very much dependent on the homeowner and thatcher working together to give the greatest lonjevity
