Types of Roof Insulation
There are several types of roof insulation, including attic insulation, pitched roof insulation, and flat roof insulation.
Attic Insulation
Attic insulation is a great way to save money on energy bills. In Ireland, attic insulation materials can cost from €7 to €28 per square metre. The price changes based on the type of material used. Dublin prices may range from €7.50 to €29 per square metre for these materials. Attic insulation helps keep your house warm in winter and cool in summer. This kind of update can also add value to your home if you decide to sell it later on.
Pitched Roof Insulation
Pitched roof insulation is important for maintaining a comfortable and energy-efficient home in Ireland. The cost of insulating a pitched roof can vary depending on factors such as the type of insulation material used and the size and complexity of the roof.
Fibreglass insulation, covering 20 square metres, can cost around £400–£500. It's worth considering this investment because pitched roof insulation helps reduce heat loss in winter and keeps your home cooler in summer.
This means potential savings on heating and cooling bills, making it a cost-effective choice for homeowners. Don't forget to check if you're eligible for any grants offered by organisations like the Sustainable Energy Authority of Ireland (SEAI), which can help offset the cost of attic insulation.
If you're unsure about what type of insulation to choose, the experts at HP Roofing can offer valuable advice.
Flat Roof Insulation
Insulating a flat roof is an important step in making your home more energy-efficient and comfortable. The cost of flat roof insulation can vary depending on factors like the size of the area to be covered and the type of insulation material used.
On average, it can cost around $0.67 per square foot to install 1-inch-thick PolyISO insulation with an R-value of six. It's worth considering this investment, as proper insulation can help reduce heating and cooling costs while improving overall comfort in your home.
Additionally, there may be grants available from organisations like the Sustainable Energy Authority of Ireland (SEAI) to help offset the cost of attic insulation.
Factors Affecting Roof Insulation Cost
The cost of roof insulation is influenced by several factors, including the type of material used, the size of the roof, and the method of installation.
Material type
Different types of insulation materials are available for roof insulation. These include spray foam insulation, mineral wool insulation, rigid foam board insulation, and sheep's wool insulation.The cost of these materials can vary depending on the type you choose. For example, in Ireland, attic insulation materials can range from €7 to €28 per square metre. It's important to consider energy efficiency, longevity, installation complexity, and potential savings when choosing the right material for your roof insulation.
So make sure to weigh all these factors before making a decision for your home.
Roof size
The size of your roof is an important factor that can affect the cost of insulation. The larger the roof, the more materials and labour will be required, which can increase the overall cost.
For example, insulating a flat roof with an area of 100 square metres can range from €670 to €2,900, depending on the type of insulation used. Similarly, insulating a pitched roof covering 20 square metres may cost around £400–£500.
So when planning for roof insulation, it's essential to consider the size of your roof, as it can impact the overall expenses involved in the project.
Installation Method
To install roof insulation, there are different methods that can be used. Some common installation methods include spraying foam insulation onto the roof, laying rigid foam board insulation, or using mineral wool insulation.
The method chosen will depend on factors such as the type of roof and the desired level of insulation. It's important to consider these factors when planning for roof insulation to ensure that you choose the most suitable installation method for your home.
Average Cost of Roof Insulation

Factors to Consider when Choosing Roof Insulation
When choosing roof insulation, it is important to consider factors such as energy efficiency, longevity, installation complexity, and potential savings on heating/cooling bills. Read on to find out more about making the right choice for your home.
Energy Efficiency
Energy efficiency is an important factor to consider when choosing roof insulation for your home. Good insulation helps to keep heat inside during the colder months and prevents it from getting in during the hotter months.
This means that you won't have to rely as much on heating or cooling systems, which can save you money on your energy bills. Additionally, energy-efficient insulation can reduce greenhouse gas emissions and help protect the environment.
It's worth investing in high-quality insulation that will provide long-term energy savings for your home.
Longevity
The longevity of roof insulation is an important factor to consider when choosing the right type for your home. Different insulation materials have different lifespans, so it's essential to select a durable option that will last for many years. For example, fiberglass insulation can last up to 20-30 years, while spray foam insulation has a lifespan of around 50 years or more. Sheep's wool and rigid foam board insulation are also known for their long-lasting properties.
By investing in high-quality and long-lasting insulation, you can ensure that your home remains energy-efficient and comfortable for an extended period without the need for frequent replacements or repairs.
Installation Complexity
Installing roof insulation can vary in complexity depending on factors such as the type of insulation material used and the size and complexity of your roof. If you have a flat roof, the installation process can be relatively straightforward.
However, if you have a pitched roof or multiple levels to insulate, it may require more time and effort. It's important to consider these factors when planning for roof insulation so that you can budget accordingly and ensure that the installation is done correctly. Hiring a professional roofing contractor who has experience with installing insulation can help simplify the process and ensure that it is done efficiently.
Remember, proper installation is crucial for maximizing energy efficiency and achieving long-term savings on heating and cooling bills. Taking into account the complexity of your roof during the planning stage will help you make informed decisions about which insulation materials to use, as well as estimate potential costs involved.
Potential Savings On Heating/Cooling Bills
Insulating your roof can help you save money on your heating and cooling bills. By reducing heat loss during colder months and preventing heat gain during hotter months, roof insulation can make your home more energy efficient.
This means that you won't need to use as much energy to keep your home at a comfortable temperature, resulting in lower utility bills. Depending on the type of insulation and the size of your roof, potential savings on heating/cooling bills can range from around 10% to 50%.
So not only will you be making your home more comfortable, but you'll also be saving money in the long run.
Final Thoughts
The cost of roof insulation can vary depending on factors such as the type of insulation material used and the size and complexity of the roof. It is important for Irish homeowners to consider their specific needs and budget when choosing roof insulation.
So, by investing in proper insulation, homeowners can benefit from energy efficiency, potential savings on heating/cooling bills, and a more comfortable living environment.
