J&B roofing can re-roof your existing roof in colorbond, gal or zinc. Your existing roof will be stripped, re-battened and therma-foiled as the team moves through taking a deteriorated roof to a fantastic new looking, watertight roof. If colorbond is your choice of roofing material, then why not use J&B's computerized colorbond selector to make the decision, making process easier from the eighteen colors.
