Roof Insulation
Different types, opportunities and subsidies
Say new roof, you say roof insulation. These days, everyone is talking about insulating their home. Roof insulation has the most to gain, which is why most people start there. A change that VIP Dakservice jumped right into. We delved very deeply into the best types of roof insulation and included a nice selection in our portfolio. Discover the different options, both for flat and pitched roofs.
Choices in roof insulation
When you want to insulate your roof (better), there are several choices to make. Do you want to insulate your roof from the outside or from the inside? Which material do you choose? And do you go for vapor-open or vapor-tight insulation?
Our roofers understand that this may not mean much to you and that you could use some advice. We always try to help you as best we can and objectively explain the possibilities, differences and choices for your roof. Of course we can also advise you based on our experience on other roofs and with different types and brands of materials.
Is your roof in need of replacement and would you like to take a closer look at your roof insulation? The roofers of VIP Dakservice will gladly visit you to check the condition of your roof + insulation. We go up on the roof for a free roof inspection and map the situation based on photos. You will then receive a quote from us containing our advice and the cost of replacing your roof and installing any additional roof insulation, again without obligation. We will explain different choices and, if you wish, also the difference in price. This way you can always make an informed choice when choosing roof insulation.
Vapor-open or vapor-tight insulation?

Roof insulation on the outside or inside?
People who live in older homes often have roof insulation on the inside. That is the way that has traditionally been used. Today, roof insulation is often installed on the outside. Due to developments in the field of roof insulation, products have come on the market that make insulation from the outside a lot easier and are very durable.
Roof insulation from the outside
When your roof needs replacing, you often see that the current roof insulation has also had a lot to endure. When new tiles are put on your roof anyway, it is a good time to decide whether you also want new roof insulation. From the outside, we at VIP Dakservice almost always work with Kingspan Unidek. These are roofing elements that insulate your home very well, are efficiently designed and really offer a solution for every home. We at VIP Dakservice stand behind the quality of Kingspan Unidek and often recommend it for our customers. In almost all cases, Kingspan Unidek boards come standard with a vapor-permeable film on the outside; that’s one less worry.
Roof insulation from the outside has several advantages:
- You achieve the best insulation value when you insulate your roof from the outside. You’ll see this reflected on your energy bill.
- You don’t lose space inside because the insulation will be on the roof structure, not under it.
- The entire roof structure is protected from moisture and cold because the insulation is on top.
- There is less chance of thermal bridges forming. Roof insulation on the outside can be completely sealed, which is often not the case with roof insulation on the inside.
- The insulation is installed from the outside, so you won’t experience clutter and inconvenience in your home.
- You don’t have to change or demolish anything on the inside of your house. Any bedrooms and other rooms that are under the roof can simply stay in their original state.
Disadvantages of exterior roof insulation:
- Your roof tiles will be many centimeters higher in some cases, so it is not always possible to insulate with insulation boards if you live in a mid-terrace or semi-detached house, for example.
- The roofing needs to come off. Often this is not a disaster when your roof needs to be replaced anyway, but in other cases it can be a drawback.
- It requires additional materials, such as scaffolding and boom lifts – again, this is only a disadvantage if you are not going to replace your roofing yet. If your roofing is being replaced anyway, you can’t consider this a disadvantage.
- Drainage, downspouts and gutters need to be modified in many cases.
Insulating roof from the inside
As mentioned above, roof insulation from the inside is done less and less often these days. People often still choose roof insulation from the inside because it is relatively cheaper to install than roof insulation from the outside. It is also easier to “just” do yourself: just attach some insulation material to the roof structure and you’re done. In practice we often see that it does not work as well as we thought.
Advantages of roof insulation from the inside:
- Roof insulation on the inside of the roof is cheaper than from the outside.
- Often placed within 1 day.
- No need for additional materials such as aerial platforms and scaffolding.
Disadvantages of insulation on the inside of your roof:
- Ceiling has to be removed in many cases, which creates a lot of mess as well as extra work.
- The insulation value is lower for insulation from the inside than for insulation from the outside.
- You lose space because you are bringing down your ceiling, so to speak.
- Quicker chance of moisture in insulation, which can even cause mold in the long run.
Different insulation materials
There are different materials that can be used as roof insulation. Everyone is probably familiar with the rolls of glass wool that you attach to the roof boarding. Rock wool is another material that is regularly used. These two types are often encountered when choosing roof insulation from the inside.
At VIP Dakservice we prefer roof insulation from the outside and work with sustainable materials and the latest technologies. Roof insulation from the outside often involves working with plastic roof insulation, such as EPS, PIR, PUR, XPS or PF. Advantages of plastic roof insulation is that they are very light materials with a higher insulation value than mineral wool and they are not sensitive to moisture. This makes them very suitable for all kinds of spaces.
The Kingspan Unidek insulation boards we work with a lot at VIP Dakservice can be used for both flat and pitched roofs. In many cases this roof insulation is installed within one day, so the ‘inconvenience’ for you is also minimal. A beautiful solution with a very durable result.
Subsidy for roof insulation
You can read all the rules related to grants at the website of the RFO. Our roofing specialist can also answer many questions for you, advise you on the materials needed and help you apply for the subsidy.
Cost of roof insulation flat or pitched roof
The cost of roof insulation is made up of a number of factors. For example, the number of meters obviously plays an important role, the material chosen and the amount of work. Often we do not have to come just for roof insulation, but it becomes a combination job of roof insulation installation and roof replacement.
As a guideline, we use the following prices per meter:
Roof insulation for flat roof from € 36 ex. VAT
Roof insulation for sloping roofs from € 45 ex.

Our process for insulating your roof
Is your roof really in need of replacement and do you want to know if roof insulation is smart to perform? Then we would be happy to help you and advise you on your options. You can expect the following from us:
1. Choices
At a personal meeting, including a roof inspection, we discuss the options for your roof. For example, you cannot use soft material on a flat roof; you should always attach insulation boards. We help make the choices for the type of roof insulation, quantity and matching roofing. In some cases, permits also need to be applied for. We can do this for you as well.
2. Roof insulation subsidy
After we have prepared the quotation with the reporting code and the number of square meters, you can apply for the subsidy yourself. The quote is free and will be sent to you for you to review. If you have any questions or doubts, contact us and we will adjust the quote if necessary.
3. Scheduling assignment
After agreeing to the quote and applying for the grant, we will contact you to set up an appointment to insulate your roof. We will take into account all schedules and the time we need to insulate your roof.
4. Carrying out assignment
At the appointed time, we’ll be at your doorstep to get on the roof. The roof will come off (and fortunately a beautiful new roof will take its place afterwards or we’ll put your current roofing back on neatly).
5. Evaluation
When the project is completed, we take time for an evaluation. We use photos to show you how the roof was constructed. These photos are also shared with you. In addition, we are very curious; how did you experience the entire process, are you satisfied and are there any areas of improvement for us? We also always ask if you would like to share your experience, for our future customers.
