Roofmaster has been operating in the Northern Territory Top end region since 1984. It is a local family owned business that had its origin as a small supply and install company. It has continued to grow in size, becoming the size it is today. The company has been a member of the Master Builders association (formerly the Territory Construction Association) since 1985. Roofmaster is one of the very few companies in Australia that offer lead free soft feed ridge cap flashings. The use of this product eliminates the need to scribe in the ridge caps thus saving many hours of labour. With the continual growth of Roofmaster, our sister company Metalmaster was born and it is under this umbrella that all our flashings, rainwater goods and stainless steel products are produced.
