Roof insulation and thermal insulation
for private homes

Roof insulation and thermal insulation: home comfort and lower heating costs

Properly installed roof insulation is one of the most effective ways to reduce heat loss in a home. A significant amount of heat escapes through an uninsulated roof — leading to higher heating bills in winter and overheating of rooms in summer. We carry out roof structure insulation and roof thermal insulation for private homes, taking into account the roof construction, the condition of the rafter system and the selected roofing material. We select suitable materials, calculate the required thickness, design all junction details and work carefully — so that the insulation delivers real results, not just figures on paper.

When roof insulation is needed for a private home

Roof insulation for a private house is relevant both for new builds and for renovation of existing homes. If rooms feel cold despite normal heating operation, damp patches appear on ceilings, moisture is noticeable in the loft, or icicles and ice form on the roof in winter — these are clear signs of heat loss and problems with vapour control or ventilation. Roof thermal insulation is also essential if you plan to convert a loft into living space or want a stable indoor climate all year round.

Roof insulation from the outside or from the inside — which option to choose

Depending on the condition of the roof build-up and the specific task, we select the most appropriate approach. Internal roof insulation is most often used when the roofing has already been installed and there is no intention to dismantle it. In this case, we work along the rafter system: install the insulation, fit vapour control layers and carefully seal all joints and connections to prevent moisture from entering the insulation layer. This is crucial, as damp insulation loses its thermal performance and can quickly lead to mould growth and timber decay.

External roof insulation is usually chosen when maximum reliability and long-term performance are required — during roof reconstruction or in new construction. From the outside, it is easier to correctly assemble all layers: insulation, wind and waterproof membranes, ventilation gaps, battens and the final roofing covering. This approach ensures stable roof thermal insulation for the house and protects the structure from temperature fluctuations.

How we carry out roof thermal insulation

High-quality roof thermal insulation is more than simply “installing insulation”. It is essential to create a system where every layer works effectively: vapour control prevents moist indoor air from entering the structure, membranes protect against wind and external moisture, and ventilation removes condensation. That is why we begin with an inspection and measurements — assessing the condition of the rafters, roof geometry, ventilation openings and channels, and identifying weak points such as valleys, junctions with chimneys, roof windows and the ridge area.

We then select a solution suited to your home and budget: insulation type, thickness, installation method and junction details. After that, we prepare a clear cost estimate and work plan. During installation, we strictly follow the technology and carefully seal all joints to eliminate thermal bridges. As a result, roof insulation is durable and safe for the roof structure.

What determines the cost of roof insulation

Cost is always an important factor, so we explain in advance what influences roof insulation costs. The final price depends on the roof area and complexity (slopes, valleys, complex geometry), the condition of the base and rafters, site access, the need to remove existing layers, as well as the selected materials and their thickness. For this reason, enquiries such as “roof insulation price” are best calculated after an inspection or based on your measurements and photos. This way, you receive a realistic quote with no unexpected extras.

Turnkey roof insulation — what you get

By choosing turnkey roof insulation, you receive a complete service: consultation, selection of the appropriate technology, calculation of materials and thickness, installation with all roof build-up layers respected, and quality control. We work to ensure that after completion your home is noticeably warmer in winter, more comfortable in summer, and that the roof performs reliably for years without moisture, condensation or hidden damage. You clearly understand what you are paying for and see the benefit not only in comfort, but also in reduced heat loss.

When to get in touch and how quickly we can start

You can contact us at any stage: during construction, renovation, or when heat loss problems have already appeared. Ideally, insulation works are planned in advance, but we also often help in urgent situations when it is necessary to quickly improve roof thermal insulation. Leave an enquiry — we will review the roof structure, recommend insulation from the inside or outside, calculate materials and provide an accurate cost estimate.
