Decramastic Roofing Gold CoastExpert Decramastic to Metal Roof Replacement
Is your decramastic roof showing its age? Our QBCC licensed team specialises in replacing deteriorating decramastic roofs with modern Colorbond steel — built to handle Gold Coast conditions for decades.
What Is a Decramastic Roof?
Decramastic roofing consists of pressed metal tiles coated with stone chips or granules bonded to the surface. These roofs were widely installed across Queensland homes during the 1970s and 1980s as an affordable and attractive roofing option.
While they served well initially, decades of exposure to Gold Coast's intense UV, salt spray, and subtropical storms have caused most decramastic roofs to deteriorate significantly. The stone coating breaks down, exposing the metal beneath to corrosion.
If your home was built between 1970 and 1990 and has textured, granular-looking tiles, you likely have a decramastic roof that may be due for replacement.
Common Decramastic Roof Problems
Gold Coast's coastal climate accelerates decramastic deterioration. Here are the issues we see most often.
Coating Failure
Gold Coast UV exposure accelerates stone chip coating breakdown, leaving bare metal exposed to the elements.
Rust Development
Once the protective coating fails, salt spray and coastal humidity cause rapid corrosion and rust formation.
Poor Storm Resistance
Aging decramastic tiles lose structural integrity, making them vulnerable to Gold Coast storm damage and high winds.
Moss & Mould Growth
The textured surface traps moisture in humid conditions, encouraging moss and mould growth that accelerates deterioration.
Difficult to Repair
Replacement tiles are no longer manufactured, making effective repairs virtually impossible.
Gutter Blockages
Loose stone chips wash into gutters and downpipes, causing blockages and water overflow damage.

Decramastic Roofing FAQs
Common questions about decramastic roof replacement on the Gold Coast.
How do I know if I have a decramastic roof?
Decramastic roofs are made of pressed metal tiles coated with stone chips or granules. They were popular in Queensland during the 1970s and 1980s. They have a distinctive textured, granular appearance — if your tiles look like metal sheets covered in small stones or grit, you likely have a decramastic roof. We can confirm during a free inspection.
How much does decramastic roof replacement cost on the Gold Coast?
Decramastic roof replacement on the Gold Coast typically ranges from $15,000 to $40,000+ depending on roof size, complexity, and the Colorbond profile selected. This includes complete removal of old decramastic tiles, structural assessment, and installation of a new metal roofing system. We provide free, detailed quotes for every project.
Can a decramastic roof be repaired instead of replaced?
While minor repairs are possible, decramastic roofs generally cannot be effectively repaired long-term. The stone coating deteriorates uniformly across the roof, meaning patching one area still leaves the rest vulnerable. Replacement tiles are no longer manufactured, and painting only provides temporary relief. Full replacement with modern Colorbond is the recommended long-term solution.
How long does a decramastic to metal roof conversion take?
A typical decramastic to metal roof conversion on a Gold Coast home takes 3-5 days depending on the size and complexity of the roof. This includes removal of the old decramastic tiles, structural inspection and any necessary repairs, installation of new battens if required, and fitting the new Colorbond roofing.
What material replaces decramastic roofing?
We replace decramastic roofs with premium Colorbond steel by BlueScope. Colorbond is specifically engineered for Australian conditions and offers superior heat reflection, cyclone-rated strength, salt spray resistance, and warranties up to 36 years. Popular profiles include Trimdek for residential homes and Kliplok for low-pitch applications.
Is decramastic roofing dangerous?
Decramastic roofing is not inherently dangerous like asbestos, but deteriorated decramastic roofs pose safety risks. Loose stone chips can block gutters and downpipes, corroded tiles may leak causing water damage and mould, and weakened tiles can become dislodged in storms. A deteriorated decramastic roof should be replaced to protect your home and family.
