What is roof insulation?
Roof insulation is an insulation material installed between the joists or the rafters of the roof to create barriers within your roof space.
The boards are designed to create a vertical thermal barrier on the building, hence significantly decreasing the amount of heat that leaves your house in the winter as well as reducing the amount of thermal heat entering your home in the summer.
However, you will need to adopt a different method if you are dealing with a pitched roof or a flat roof, and then choose if you will insulate your roof at rafter level for a warm or cold roof.
Things to consider before insulating your roof
You need to consider several aspects before insulating your roof so that you can get the optimal solution for it. Ask yourself these questions.
- Do I need warm or cold roof insulation?
- Is there existing insulation in my roof?
- Do I have a flat or pitched roof?
- Does my house suffer from condensation?
- Where are the water tanks and pipes located?
- Is the roof’s hatch insulated?
- Are there recessed halogen lights in the room before the roof?
If you get answers to these questions, your project should be quick and flawless.
Type of insulation for your roof
Here at Insulation Wholesale we offer four main types of roof insulation;
Flat roof insulation
This one comes in three different forms: inverted roof, a warm deck roof and a cold deck roof. In warm deck flat insulation, the insulation is fixed over the roof deck immediately after the timbers and joists. In cold deck flat insulation the insulation is placed below the deck and the joists.
Inverted flat roof insulation is not as common as it is only used in cases where the flat roof would be transported. It is preferred in these circumstances because it provides more reliable and stable surface. Typically, the insulation is fixed as a final layer, above weatherproof membrane and the breather. This also protects the weather-resistant membrane.
Pitched roof insulation
A pitched roof is a traditional roof with a loft space, accessed through a hatch. Pitched roof is insulated in two ways:
- Warm roof – the insulation is fixed below the roof to trap warm air in the loft space. For warm pitched roof, we recommend insulation such as Kingspan Kooltherm K07. You would also need to fit a breathable membrane such as Kingspan nilvent above the insulation.
- Cold roof – this is quite popular. The insulation is fitted over the ceiling. It is intended to maintain the rooms below warm. However, the loft remains cold, hence the name. In this, we also recommend Kooltherm K07 pitched roof panel.
Rigid roof insulation
With various top brands including Recticel and Kingspan, rigid roof insulation boards from Insulation Wholesale are suitable for almost all types of applications. Apart from being used in roof insulation, the rigid boards are also utilised in floors and walls for retrofitting old structures, new build and large scale construction jobs.
Benefits of roof Insulation
Here are three main benefits of roof insulation:
- Long-term prevention – let’s assume there would be a ‘big freeze’ next winter (this is a common occurrence nowadays in the UK). In this case, your house could be covered with up to 5 inches of snow. This is where the problem starts. If your roof is improperly insulated, heat will escape from the roof and speed up the snow melting on the roof, thus creating ice dams. House dams, condensation, and moisture can have adverse effects on your home. To get the best performance, you need to have rigid roof insulation, not only to your roof but also to all other building parts.
- Energy and cost savings – there is no doubt you will save energy and some bucks if you have proper roof insulation. Roof insulation helps you regulate the amount of heat leaving or entering your home. Generally, a homeowner saves up to £200 per year through roof insulation.
- Environmental sustainability – roof insulation not only benefits you in terms of savings on energy costs, but it also benefits the environment. You actually take an active role in reducing the concentration of pollutants from the environment.

FAQ
How much does roof insulation cost in the UK?
The cost of roof insulation depends on the material, roof design, and total coverage area. Insulation thickness and performance also affect pricing, with prices for most products starting at £20-£40 per square metre for material only.Thicker or higher-performance products typically cost more per m².
Phenolic and PIR boards usually cost more upfront but provide higher thermal performance, helping you achieve target U-values with thinner layers.
How thick should roof insulation be?
Thickness varies based on the material and type of roof system used. In most UK homes, roof insulation ranges between 100mm and 270mm in thickness depending on whether it is a flat or pitched roof.
Around 150mm–180mm of PIR insulation is common for flat roofs, while lofts and pitched roofs require about 270mm of mineral wool to comply with current UK Building Regulations.
What roof insulation is best?
Your roof type and project goals determine the best product to use. Each type has its perks, so choose based on your roof structure and what you hope to achieve.
- PIR boards deliver high performance with minimal thickness and are excellent for flat roofs and warm roof systems.
- Phenolic foam boards are very thin yet deliver superior efficiency depending on brand and thermal conductivity. They are perfect for height-restricted roof spaces.
- Mineral wool rolls are sound absorbing, easy to lay and affordable. These are commonly used in cold roof or loft insulation applications.
What is roof insulation made of?
Roof insulation can be made from several materials. The most widely used are mineral wool(rock or glass), PIR boards, phenolic foam, polystyrene (EPS or XPS) and natural materials like wood fibre or sheep wool.
