During the 1950s and 1960s Len Phipps grew a successful roofing contracting business serving the south west. In the 1980s, faced with the challenge of erratic supply of indigenous slate, his son Peter discovered new sources in Spain and Brazil. Good contacts, reliability and regular supplies lead a growing number of local roofing merchants to rely on Peter for their natural slates.
