A factory roof in Cyprus had major issues with water ingress, causing numerous problems internally inside the building. The roof was previously covered with bitumen, a type of asphalt commonly used for flat roofs. Bitumen can breakdown prematurely in fluctuating climate and weather conditions. In the heat of the summer months, the bitumen had cracked along the joints allowing the rainwater to seep through the existing membrane. Moreover, bitumen tends to absorb rather than reflect heat which can superheat the building below. A long-lasting solution was needed to re-waterproof the roof.
