Why your insulate roof
Your roof
Heat rises, and a poorly insulated roof is often the biggest source of heat loss in the home. You will notice this from cold rooms under the roof, draughts, and heating bills that are higher than necessary. A well-insulated roof keeps the warmth inside in winter and the heat outside in summer, making your home feel more comfortable all year round.
We examine how your roof is constructed and where the insulation will have the most effect. We then advise on the approach and insulation value that suit your roof and your requirements. This way, you invest purposefully in comfort and savings, without doing more than is necessary.

Insulate at the right time
The right time
Insulating a flat roof is usually done on the outside, beneath the new roofing. That is the ideal moment: when the roof is being opened up anyway, we install the insulation boards properly in one go and lay the bitumen roofing neatly over them. In this way, you get a roof that insulates while also being waterproof again for years to come.
External insulation has the advantage that you do not lose any space inside and that cold bridges are tackled more effectively. We advise the correct insulation thickness for your situation and ensure a neat connection to the edges and upstands. See also our roofing if the roof is due for a new layer.
Insulate roof from the inside or outside
Flat roof
With a pitched roof, the insulation can be placed on the inside, between and under the rafters, or on the outside under the tiles. The inside is often quicker and more cost-effective, while the outside is more thorough and is usually combined with new roofing. Which approach is best depends on your roof, your plans and your budget.
We will inspect your roof and present the options to you with their pros and cons clearly laid out. This allows you to make a choice that suits your home, without having any more work done than is necessary. The end result is a roof that retains heat and is finished to a high standard.

How much does a roof insulation in Katwijk?
Cost
The costs depend on the approach, the surface area, the chosen insulation value and whether the work is combined with new roofing. Combining it with work you are having done anyway reduces the price per square metre. That is why we do not quote a figure in advance; every situation is different.
Following a no-obligation inspection, you will receive a fixed price in writing and you will pay what has been agreed, with no surprises afterwards. There are sometimes grants or schemes available for insulation. We will point you in the right direction where possible, but you must apply for them yourself.

All the guttering around the house was replaced because the old lead guttering had worn out after thirty years; it was done neatly and quickly.

Our holiday home suffered considerable roof damage after the autumn storms, and we only noticed it weeks later when the caretaker noticed the water spots. Through Dakdekker Specialist De Duinen it was quickly resolved; it was also nice that they could coordinate directly with the caretaker so that we didn’t have to drive there.
