our testimonials

"Charlie and his team totally transformed the look of our home by replacing the old worn tiles with a beautiful new Colour-bond roof. He was on time, budget and a delight to do business with.”

Steve and Vanessa - Newhaven

“Charlie is a true tradesman. We had a full reroofing, gutters and down pipes replacement plus new building flashings. His attention to detail was outstanding. We also appreciated his focus on safety on what is inherently a dangerous job.”

Dave - Surf Beach

“Charlie provided an excellent service from start to finish. His communication was clear and consistent, and he was always available to answer questions. He demonstrated a strong understanding of the product and offered valuable ideas that enhanced the final result. His pricing was fair and competitive, and the overall experience exceeded our expectations. Charlie came highly recommended, and we’re very pleased we decided to work with him.”

Jac - Hume

Led by seasoned roofing specialist Charlie Denniston, our business brings over 15 years of hands-on experience in roofing and plumbing to homes and businesses across Phillip Island and beyond.

We specialise in all things metal roofing and cladding — from new builds and re-roofs to roof maintenance. No job is too big or too small. Whether it’s a complete re-roof or a quick fix to resolve a roof leak, you’ll get the same high standard of workmanship and service we’re known for.

What sets us apart? Clear, open communication and zero surprises. You’ll always know exactly what work is being done, when and what it will cost. We’re reliable, responsive, and committed to delivering results that last.

If you're after a roof that’s built to endure and a team that delivers with integrity, you’re in the right place.
