If your home was built or renovated in the 1970s or 1980s, there’s a good chance your roof might be made from decramastic tiles, a product that was once considered innovative and affordable. But fast forward a few decades, and many Aussie homeowners are discovering that these roofs don’t quite stand the test of time.
If you’ve noticed wear and tear on your roof or you’re thinking about upgrading, here’s what you should know about decramastic roof replacement.
What is a Decramastic Roof?
Decramastic roofs are made from lightweight, pressed metal tiles. These were often coated with a bitumen layer and sprinkled with stone chips to mimic the look of traditional tile roofs. They were popular for their price and ease of installation, and many were even installed directly over existing roofs.
But here’s the thing: these tiles weren’t built to last forever. Over time, they’ve shown a tendency to dent, rust, or deteriorate, especially under Australia’s harsh sun and storms.
And if your roof is older, there may be another serious concern: asbestos. Some early versions of decramastic tiles contained asbestos, a health hazard when disturbed.
How to Tell If You Have a Decramastic Roof
Not sure what’s up there? Here are a few clues your roof might be decramastic:
- The tiles are thin, lightweight metal, not concrete or terracotta
- They have a stone-chip finish that’s worn or patchy
- The surface looks dented or “bubbly”
- Your home was built or renovated between the 1970s–1990s
If this sounds like your roof, it’s worth getting a professional inspection, especially if you’re considering repairs or renovations.
Why Homeowners Are Choosing to Replace Decramastic Roofs
Many homeowners today are replacing their decramastic roofs for a few key reasons:
- Damage over time: These tiles can easily dent from hail or people walking on the roof.
- Leaks: As the coating wears off, the roof becomes more prone to leaks and rust.
- Asbestos risk: Older tiles may contain asbestos, which requires special handling and removal.
- Curb appeal: Many of these roofs look dated compared to modern options.
If your roof is showing its age or you want to add value to your home, replacement is often a smarter investment than ongoing patch-ups.
What’s Involved in Replacing a Decramastic Roof?
Here’s a quick look at the process:
- Inspection: A roofing expert will inspect your roof for damage, check for asbestos, and advise on the next steps.
- Asbestos Testing (if needed): If asbestos is suspected, certified professionals will test and, if necessary, safely remove the material.
- Removal of the Old Roof: The old decramastic tiles are taken off, and the underlying structure is checked for damage or rot.
- Installation of a New Roof: This is your chance to upgrade! Many homeowners choose modern materials like Colorbond steel: strong, stylish, and built for Aussie conditions.
- Optional Upgrades: Need better insulation or roof ventilation? It’s often cheaper to add these during a roof replacement than later.
What Are the Benefits of Replacing with Modern Roofing?
Replacing your decramastic roof isn’t just about fixing problems, it’s an opportunity to upgrade your home in big ways:
- Stronger materials that can handle harsh weather and last decades
- Lower maintenance, so you’re not constantly chasing leaks or rust
- Better energy efficiency, especially if you add insulation
- Modern aesthetics: a new roof can transform the look of your home
- Peace of mind, knowing you’re no longer dealing with asbestos or outdated materials
What Will It Cost?
The cost of replacing a decramastic roof in Brisbane typically ranges between $90 to $120 per square metre. For an average-sized home, this translates to a total cost of approximately $15,000 to $24,000, depending on various factors such as roof size, complexity, and the presence of asbestos.
It’s important to note that these figures are estimates and actual costs can vary based on specific project requirements. For a more accurate assessment, it’s advisable to consult with local roofing professionals who can provide detailed quotes tailored to your home’s needs.
