Frequently Asked Questions

What is a decramastic roof, and why does it often need replacing?

A decramastic roof is made from lightweight galvanised steel tiles coated with bitumen and stone chips. Popular in the 1970s and beyond, these roofs offered an affordable alternative to traditional tiles. However, the bitumen layer degrades under UV exposure, leading to rust and water ingress. The thin steel dents easily, especially under hail or foot traffic. Insurance companies often flag aging decramastic roofs as high-risk, and even if surface damage seems minor, hidden corrosion usually means replacement is a better long-term solution than ongoing repairs.

Can a decramastic roof be repaired instead of replaced?

Small repairs are possible but rarely recommended for aging decramastic roofs. Recoating or patching can buy time, but the underlying issues, such as widespread corrosion and failing fixings, often continue unchecked. Finding matching tiles is difficult, and isolated repairs usually do not prevent future leaks. Over-cladding systems exist, but unless properly ventilated, they risk trapping moisture. Generally, if more than 20 percent of the roof shows damage, full replacement is the more practical option.

What materials are best for decramastic roof replacement?

Colorbond steel is a top replacement choice because it is lightweight, durable, and available in many colours and profiles. For homeowners wanting to keep a tiled appearance, modern stone-coated steel shingles (such as Gerard or Tilcor) are highly recommended. Some opt for heavier concrete or terracotta tiles, but these often require expensive structural upgrades. Standing seam metal roofing is gaining popularity for modern designs, though it comes at a premium. Material choice should balance looks, performance, and structural load.


What are the signs that my decramastic roof needs replacing?

Visible dents, flaking or faded coating, rust spots, and loose or lifting tiles are strong warning signs that a decramastic roof is reaching the end of its life. Leaks during rain, sagging sections, or signs of water damage inside your ceiling are even more serious. Even if the roof appears intact from a distance, it is worth arranging a professional inspection if the roof is over 20 years old, as hidden corrosion is common.


How long does a decramastic roof replacement take?

Most decramastic roof replacements take between three and seven days, depending on the size and complexity of the roof. Weather delays can extend the timeline, especially during rainy seasons. If significant structural repairs are needed after the old roof is removed, this can add extra days to the project. A good roofing company will provide a realistic schedule upfront and keep you updated if anything unexpected comes up.
