Replacing a Decramastic Roof With A New Metal Roof
Replacing your existing Decramastic roof with a new metal roof is one of the best investments you can make for your home.
Over the years, many homes on the Central Coast especially those built in the 1960s, 70’s and 80’s had Decramastic or metal roof tiles installed
While these roofs served their purpose they quickly showed signs of aging, wear, and vulnerability and we are replacing more and more of these roofs each year as they reach the end of their time limit.

Why Replace Your Decramastic Roof?
Decramastic roofs are made of pressed metal tiles coated with stone chips.
The base is usually galvanized steel, and the chips are bonded with bitumen. This gives the roof a textured, stone-like appearance.
These roofs came in various colors and styles to mimic other materials.
You’ll often see them imitating clay tiles or slate. The metal core makes them lighter than traditional tile roofs and they were quick and light to install which was the main reason they were popular
However, with time, these roofs can suffer from a range of issues, including rust, dents, and the growth of moss and lichen, which can compromise the roof’s integrity and appearance. Additionally, they are difficult to repair and if anyone who needs to access the roof, the tiles are almost impossible to walk on.
They are thin and brittle and every step on them would result in dents and repairs are challenging because matching old tiles is hard.
Patching often looks obvious so many homeowners are choosing full replacement when major issues arise
Their thermal efficiency was not the best either which leads to increased energy costs.
Replacing your old Decramastic roof with a modern Colorbond metal roof provides a stylish, durable, and energy-efficient solution that can withstand Australia’s harsh climate.
The Benefits of Colorbond Roofing
Colorbond steel is a popular roofing material in Australia, known for its exceptional durability, wide range of colours, and resistance to corrosion. It has been specifically designed to meet the demands of the Australian environment, making it an ideal choice for homeowners looking to replace their aging Decramastic roofs.
- Durability and Longevity: Colorbond steel is incredibly durable, withstanding the test of time and the elements. Unlike Decramastic roofs, which deteriorate over time, Colorbond roofs are built to last. They are resistant to chipping, peeling, and cracking, ensuring your roof remains in excellent condition for decades.
- Energy Efficiency: One of the standout features of Colorbond roofing is its energy efficiency. Also choosing a lighter colour will reflect more of the sun’s heat, which helps to keep your home cooler in summer and reduces the need for air conditioning. This not only lowers your energy bills but also contributes to a more sustainable and environmentally friendly home.
- Aesthetic Appeal: Colorbond roofing is available in a wide range of colours, allowing you to choose a shade that complements your home’s style and surroundings.
- Low Maintenance: Unlike Decramastic roofs, which require regular maintenance to prevent moss and lichen growth, Colorbond roofs are relatively low maintenanc and their smooth surface makes it difficult for dirt and debris to accumulate.

Roofing Aftercare and Maintenance
Taking care of your new roof is key to making it last. Regular checks and quick fixes can prevent big problems down the road. Here are some tips to keep your roof in top shape.
Addressing Minor Repairs Promptly
Fix small problems fast to avoid bigger ones later. Replace cracked or missing tiles right away. Seal any gaps or holes you find.
For metal roofs, touch up scratches with paint to prevent rust. Tighten loose fasteners and replace any that are rusted.
If you see water stains on your ceiling, act fast. Find the leak and patch it up. Don’t wait for the next rain to test your fix.
Long-Term Care Tips
Keep your roof and gutters clean. Dirt and grime can lead to decay over time.
Check your roof cavity for proper ventilation and we recommend installing whirlybirds to provide airflow. Good airflow helps prevent moisture buildup and extends your roof’s life.
Plan for a pro inspection every few years. They can catch problems early and suggest upgrades to protect your roof.
