Roof Insulation Retrofit Services for Older Homes
Many older Sydney homes suffer from insufficient, damaged, or missing insulation — contributing to excessive heat gain, poor energy ratings, and uncomfortable living spaces. Our insulation upgrade service includes the removal of existing materials, cavity cleaning, and the installation of new, high-performance insulation products with correct R-values tailored to your property’s needs.
We retrofit ceiling insulation in tight-access roof spaces, install thermal blankets under metal roofs, and apply foil sarking to improve radiant heat control. These upgrades reduce indoor temperature swings, ease pressure on air conditioning systems, and create more thermally stable homes — with results you can feel in every season.
Remove and Replace Old or Ineffective Insulation
Old insulation can degrade over time due to moisture, dust, pests, or previous poor installation. We provide full insulation removal, vacuum roof cavity cleaning, and safe disposal, followed by expert reinstallation of compliant materials. This service is ideal for homes with musty roof odours, water damage, or uneven temperatures between rooms.
Retrofit Foil Sarking and Radiant Barriers
If your home has no sarking under the roof, we install foil-backed reflective barriers designed to repel up to 95% of radiant heat. Foil sarking also prevents condensation and protects against moisture intrusion. It’s especially effective under metal roofing, where radiant heat and noise levels are highest.
Upgrade with Solar-Powered Roof Ventilation Systems
We supply and install cutting-edge solar-powered roof vents that operate silently and automatically based on internal temperature. These vents provide continuous air extraction without adding to your electricity bill, making them perfect for homes looking to improve energy performance with zero ongoing costs.
Increase Energy Ratings and Property Value
A properly ventilated and insulated roof space directly contributes to better energy efficiency ratings, reduced utility costs, and higher resale value. Whether you’re preparing for a BASIX assessment, improving an investment property, or upgrading your own home, our services are designed to meet modern expectations for thermal comfort and environmental performance.
Sydney Roofers offers complete roof ventilation and insulation upgrades that bring outdated systems into the modern era. Our expert solutions are tailored to Sydney’s climate, roof styles, and compliance standards, ensuring every retrofit delivers maximum performance and lasting benefits.

Upgrade Your Whirlybird or Install Advanced Roof Vents
If your existing roof vents are rusted, ineffective, or improperly installed, we offer a complete upgrade service that includes the removal of old whirlybirds and the installation of modern alternatives. Our range includes wind-driven whirlybirds, solar-powered exhaust fans, and passive vent systems — all designed to increase airflow, prevent moisture buildup, and reduce attic heat by up to 30% in summer.
We position vents strategically for optimal airflow using principles of passive cooling and natural draw. Every new vent system is installed with storm-proof flashings, roof sealing, and wind-rated components suitable for Sydney’s climate. We also offer upgrades for properties with no previous ventilation — improving roof space health, indoor comfort, and energy efficiency in one service.
