Colourbond Roof and Guttering Installation We requested the Duravex roofing for Colorbond Roof, and guttering quote and we received the quote next day, we were amazed to see how detailed quote was drafted. The delivery and installation dates were effectively and kindly conveyed by the office employees. Despite being warned that there would be a wait because of all the rain, it only took a little under two weeks. The delivery person was accommodating and moved the guttering out of the way, and the two installers were knowledgeable, courteous, and competent. The company is beyond exceptional. I will highly recommend Duravex Roofing for your roofing and guttering requirements.
