For a 3 bedroom single storey home, a COLORBOND roof replacement usually starts from around $19,000, including removal of the old tiles, new roof battens where needed, sarking or insulation blanket, COLORBOND sheeting, flashings and cappings.

What does a roof replacement involve?

A roof replacement is the right choice when a roof has aged too far to be restored, for example when tiles are failing across the whole roof, the roof has been patched many times, or leaks keep coming back. A typical replacement includes:

• Safety setup, including guard rail and scaffolding where required.
• Stripping and removing the old roof covering and taking it away.
• Checking the roof frame and replacing damaged battens or timbers.
• Installing sarking or an insulation blanket under the new roof.
• Installing the new tiles or COLORBOND sheets, with new flashings, valleys and cappings.
• Connecting to existing or new gutters and downpipes.
• A full clean up of the site.

Why choose COLORBOND steel?

• Lighter: much lighter than tiles, which puts less load on the roof frame.
• Low maintenance: no pointing to crack and no tiles to break or repaint.
• Weather resistant: made to handle Australian conditions, including heavy rain and wind.
• Range of colours: to suit both modern and traditional homes.
• Insulation options: an insulation blanket under the sheets helps with heat and rain noise.

What affects the cost of a roof replacement?

• Roof size and shape: more area, hips and valleys mean more material and labour.
• Number of storeys and pitch: higher and steeper roofs need more safety equipment.
• Roofing material: COLORBOND, concrete tiles or terracotta tiles.
• Removal of the old roof: including any asbestos, which must be removed by a licensed contractor.
• Frame condition: rotted battens or timbers that need replacing.
• Insulation and sarking: the type and grade chosen.
• Gutters and downpipes: many people replace them at the same time.
• Access: tight sites or limited space for skip bins and materials.

Should you restore or replace your roof?

If your tiles and frame are still sound, a restoration is far cheaper, usually $4,500 to $6,500 for a typical 3 bedroom home. See our roof restoration cost guide for details. If the roof is failing across the board, a replacement is the better long term investment. We inspect the roof and explain both options honestly.
