What does roof insulation cost?

Good roof insulation is essential for a comfortable living experience. If you suffer from gusts of wind or light drafts in the house, you lose a lot of heat. Warm air rises and leaves through your roof again. For this reason, you set the heating higher, which in turn costs you more energy and therefore yields a higher energy bill.

To break this circle it’s advisable to choose a suitable roof insulation.

Insulating your roof: which elements determine the costs?

The costs that will ultimately appear on the final invoice largely depend on the type of roof that your house has. Below you’ll find a clear explanation of the different variants for insulating sloping and flat roofs.

Trussed roofs insulated from inside or outside

Trussed roofs can be insulated in different ways, namely from the inside or the outside of the roof. With roof insulation on the inside of your roof, the insulation plates are placed between the wooden beams of your roof structure. Often use is made of natural insulation wool, such as glass wool. Glass wool insulation is easy to cut to size.

This method is often used if your attic is not yet finished or if the finish is due for replacement, otherwise the entire interior must be loosened specially. Since the roof insulation consists of insulation plates, there is a chance that thermal bridges will arise.

If you opt for roof insulation from the outside, the existing roof covering must first be removed before installing the roof insulation panels. There is a wide range of insulation boards, so ask your professional about the reason why he or she works with certain material.

Since you’ve to remove the existing roofing and apply a new finishing layer, insulation from the outside is generally the most expensive variant.  In addition, with this type of roof insulation, the roof construction is well protected against moisture and various weather influences. In contrast to insulation from the inside, the insulation from the outside is uninterrupted, so there are no thermal bridges.

Insulate a flat roof: cold & warm roof

For the roof insulation of flat roofs, you can choose from three different insulation techniques. With a so-called cold roof, the insulation material is attached on the inside between the beams under the roof boarding. This method is mainly used with existing flat roofs, because they can have a limited height for technical reasons. In some cases, this type of insulation is not recommended, because the roof surface will be subject to large temperature fluctuations.

This allows the roof finish to expand and shrink, increasing the chance of cracking. In addition, there is a chance that the insulation absorbs the moisture from the room, which in turn causes a lower insulation value and maintains moisture. This can also affect the roof construction in the long term. It is important to place a damp-proof screen under your ceiling.To ensure that the vapor barrier remains uninterrupted, it is best to work with surface lighting after the insulation.

As soon as you opt for the so-called warm roof, the supporting structure of the roof is insulated. The roof insulation is applied from the outside of your roof between the roof covering and the roof boarding, so that the roof construction is also protected against cold and moisture. Because there are only a few roof penetrations available, the insulation layer is hardly broken.

This promotes the effect of the roof insulation. A warm roof has no cavity, this means that the roof heats up together with the house. In this way, the roof construction is more resistant to various weather conditions and there is less chance of cracking in the roof floor. In addition, external insulation ensures that the roof acts as a heat buffer. The roof stores heat during the day and releases it gradually in the evening.

With an inverted flat roof, the insulation material is placed on the roof covering, so that it is protected against moisture and cold. The layer that will protect the insulation consists of a ballast layer of gravel, wood or tiles. This type of insulation is often used especially on roof terraces, balconies or flat roofs that you regularly walk over. In most cases, the choice is made to use hard polystyrene plates as an insulating material, because they are pressure-resistant and weather-resistant.
