South Australia is renowned for its dramatic weather changes, from blistering summers to freezing winters. Your home’s insulation is essential in keeping your energy bills down and maintaining a comfortable temperature all year round. If you find your home chilly during winter and struggle to keep it cool during summer, then chances are your home Insulation may not be adequate.

Around 70% of the heat energy in a typical home passes through the roof and ceiling system. Having substandard or underperforming ceiling and roof insulation can dramatically increase the cost of heating and cooling bills. The good news is that Oz-Roof’s thermal insulation services can dramatically reduce this loss in energy. Our team has many years of experience in the industry and is passionate about helping Adelaide homeowners install roof insulation to help improve the thermal efficiency of their homes.

Reduced power bills

Reduced heating and cooling bills are the most significant benefits of upgrading roof & ceiling Insulation. In older homes with sub-standard ceiling and roof insulation, it’s not uncommon for electricity bills to be up to 25% higher than they should be. Selecting and installing quality insulation batts from Oz-Roof will reduce your energy costs and improve the comfort of your home.

Healthier environment

Reduced dust inside the home is another benefit of roof space vacuuming. Over the years, dust from various sources tends to settle in the roof space. This is particularly evident in older tiled roof homes. The fine dust can often enter the internal part of the home through down-lights, exhaust fans and any cracks in cornices. This can be pretty frustrating for anyone with dust allergies. Vacuuming the roof and ceiling space eliminates this and ensures a dust-free house for many years.

Noise reduction

Noise reduction in some homes can be a benefit of replacement ceiling insulation. The noise suppression offered is minimal in homes with very thin or blow-in style insulation. A well-insulated home with insulation batts of around 200 mm can significantly increase the noise suppression effect.


There are two main types of roof Insulation upgrades for residential homes. Each is different and provides different benefits:

Roof Insulation blanket retrofit for roof sheeting

Many homes around Adelaide are constructed with an original Iron or Colourbond roof that has no lining or insulation product fitted directly under the roof sheeting. With no insulation lining the roof sheeting, it is very easy for heat and cold to pass through the roof sheet and into the roof space. We offer the service of retrofitting foil backed insulation blankets directly under the roof sheeting. In this process, we progressively remove every roof sheet, usually two at a time, lay the new roof insulation over the framework and reinstall the original roof sheet with new roof screws. The process only takes a few days on an average roof. Still, it allows any iron roof to be retrofitted with an Insulation blanket directly under the roof sheeting, slowing the transfer of heat and cold at the source.

Roof space vacuum cleaning and re-insulating

Many homes around Adelaide have inadequate insulation and dusty roof space. In this process, we provide a solution to both of these problems. We remove any original ceiling Insulation, whether this is batts or blown-in type. Then the entire roof space is vacuum cleaned with an industrial vacuum cleaning machine. We then dispose of all the waste and re-line the ceiling with new insulation. While there are many insulation types available, we use R4 or R5 Insulation batts in most cases. Batts arrive in pre-cut rectangles suited to most ceiling joist centres, making the installation process quicker and easier.

Many of our clients get their ceiling Insulation upgraded in conjunction with a full roof replacement. It is often an Ideal time to undertake the work as we plan for the ceiling Insulation to be replaced just a matter of days before the roof replacement starts. This means that the roof space is clean and clear of years of dust and debris just before it is fully sealed off with the new Colourbond roof.


The cost of roof insulation replacement and upgrade depends on several factors such as site access, the physical size of the job being done, the original roof insulation type and the specified type and R-Rating of the new roof insulation. Every job is different, so give us a call to discuss some ballpark figures. As a general price guide:

  • To remove and dispose of the original roof insulation, vacuum clean the entire roof space, and reinstall new R4 ceiling batts will cost around $30 – $35 + GST per square metre.
  • The undertaking of a roof insulation retrofit is a little more difficult to provide an approximate figure. From past projects, a single-storey moderately sized house roof will cost around $5000+GST to have the roofing blanket fully retrofitted and have all roof screws replaced.


Yes, this is absolutely fine. Other than noise, there will be little disruption to your daily life. All the work is done through the roof, so you won't even have anyone inside the house.
It certainly can. The cost of the insulation upgrade often pays for itself over a few years in reduced heating and cooling bills.
If your house is older than ten years, there is a high chance the insulation could be better. The energy efficiency star ratings on new homes are relatively recent.
Yes, the noise suppressing effect of insulated roof sheeting versus non-insulated is significant, especially during rain events.
Ceiling insulation batts are pre-cut rectangles of Insulation foam that fit between the ceiling joists.
Yes, we can remove any insulation in your roof space. We will then clean and vacuum the entire area before reinstalling new insulation.

The process of installing insulation in ceiling spaces is relatively straightforward. Our roof insulation specialists will first remove the old roof insulation, whether batts or blown-in type. We will then vacuum clean the entire roof space. Once the roof space is clean, we will install new insulation between the ceiling joists.
