As the grass has died of thirst the mowing is off

The roof will in three to four years get the same flora as the area, which is a sandy heath only 500 yards from the beach.
For Bob: the picture you saw was probably a picture of Scandinavian settlers, maybe even coming from the same area where I live. As late as 1870, houses made of sod with turf roofs were used in the north western part of Denmark. This was a way of building houses or shelters that goes several thousand years back, may be three thousand years back, when the woods which covered Denmark were cut down by the peasants to gain new land for farming. This resulted in an ecological catastrophe in the western part of Jutland which is very sandy and borders to the north sea. This part of the country became covered with heather and was impossible to farm for the next two thousand years. The few people who managed to live there and survive had no wood for building and had to resort to sod.
Today turf roofs are used primarily on summer cottages like mine situated at the coast in sandy heath or dunes.
