Cost of Roof Insulation

Last updated: 30^th May 2019

The average cost of roof insulation projects in Australia costs on average $22,000 however costs can vary widely for smaller batt installation jobs for part of a roof (ranging from $700) to full roof insulation using high performance materials for large houses with a large per square metre roof area (over $30,000). Per square metre rates for roof insulation can cost between $40 per square metre to $100 per quare metre for labour and supply of materials.

Roof insulation can be a highly effective technique to passively improve the heating and cooling performance of your home, particularly if the roof faces North above commonly used living areas and bedrooms.

New homes built in Australia have standard levels of roof insulation as a BASIX requirement, while it is a highly recommended renovation upgrade for older houses looking to improve thermal performance.
