Why have your roof installation taken care of by Koning Dakwerk?

For new builds and extensions, planning is crucial: the roof must be watertight before interior finishing can begin, and every day of delay costs the entire construction company money. Therefore, we align our schedule with your contractor or your own schedule, and the quotation specifies when we start and when the roof will be watertight.

Because we participate in the construction from the very first layer, every detail is in one hand: the vapor barrier, the insulation, the covering, the leadwork and the gutters. One point of contact, one 10-year warranty certificate for the entire system.

What are the benefits of roof installation by a single specialist?

A roof that is right from the first layer remains trouble-free for the rest of its life.
 

One game, no gaps

Insulation, roofing, lead, and guttering connect seamlessly because one team installs everything.

Planning that is in place

Your contractor knows when the roof is watertight. Construction continues without waiting.

We insulate new roofs to current standards immediately. No subsequent insulation is needed.
 

Details right from day one

Cable entries, edges, and connections are built in, not fitted afterwards.

10-year warranty on the entire unit

We work with premium brands

For long-lasting results, we work exclusively with proven quality brands, including Monier, Wienerberger, and Bitasco.

New roof on your extension or addition

Most extensions are given a flat roof, and it is precisely there that details are economized on that will cost you dearly later: insufficient slope, an undersized valley gutter, or insulation that does not connect to the existing home. We design the roof extension so that it achieves the same lifespan as your house.

Are you considering a skylight or flat roof window If it is above the new kitchen or living room, we install the raised section directly. That is sleeker and more cost-effective than installing it afterwards.

Flat or pitched: every new roof

We install both flat roofs with bitumen roofing as sloping roofs with roof tiles on. For garages, sheds, and commercial spaces, we recommend the construction that suits the use: walkable where necessary, insulated where heated.

For a roof extension or ridge raising, we also take care of the complete new roof, in coordination with your structural engineer and contractor. This ensures that the extra floor immediately has a roof that will last for decades.

After heavy rainfall, the roof drain was leaking. After making a few calls, these guys were able to quickly fix the problem with an emergency repair to limit the damage. Thanks!

How much does a new roof cost?

The costs depend on the surface area, the roof type, and the construction: an insulated flat roof on an extension requires a different budget than a complete tiled roof on a new-build home. The desired insulation value also plays a role.

Based on your drawing or an on-site visit, you will receive a fixed price on paper, broken down by component. That is the amount you pay.

Frequently asked questions about roof installation

Do you have questions about roof installation? In this FAQ, we answer the most frequently asked questions. A roofer from Maassluis stands for clear, honest, and reliable advice.
As early as possible, preferably as soon as the drawings are ready. We then help think through the roof structure and details, and reserve the schedule so that construction does not have to wait on the roof.
Yes, that is standard procedure during installation. We coordinate the schedule and details with the contractor or construction supervisor, and you retain a single point of contact for everything concerning the roof.
Certainly. Even a smaller roof deserves a good structure; uninsulated outbuildings, in particular, suffer damage from condensation and poor drainage. You get the same fixed price and warranty.
Construction is building a roof where there isn't one yet; at renovation We are renewing an existing roof. The materials overlap, but the preparation and planning differ.
Actually never: an emergency cover on a new extension means paying twice and still a moisture risk during the construction phase. Plan the roof right the first time; call 06 219 66 766 and we will review your drawing.
