In the Netherlands, there are many different roof shapes. Think of a flat roof, a storage buidling roof, and a gable roof. Which roof structure do you think is by far the most commonly used in the Netherlands? Indeed, that is the gable roof. It's a simple roof to install, consisting of two slopes placed against each other. At Kroftman, we also use a gable roof structure for our storage buildings. We sometimes get asked if other roof structures are possible. Below, we'll tell you more about this, as well as the question of the roof height.

The gable roof of the Kroftman storage building

We sell standardized storage buildings and have chosen to equip all storage buildings with a gable roof. At the moment, we do not offer the option to choose a different roof structure. The frame of our storage buildings is made with this shape already in it. You only need to cover the frame with roof cladding and optionally skylights. The inverted 'V' shape of the roof has several advantages:

• The shape of a gable roof, the ridge, makes the roof sturdy.
• A gable roof is simple and symmetrical, allowing connections to be uniform.
• Unlike a flat roof, it provides good water drainage. You can improve this by adding a set of steel gutters and downspouts to your storage building. If you don't do this, the water from the roofs will run down the walls. This doesn't cause any further problems. The advantage of gutters and a downspout is that you can determine where you want the rainwater to drain into the ground.
• A gable roof provides extra space under the roof ridge. However, if you want to install a (additional) roll-up or overhead door in the side wall, keep in mind that this door will be lower than in the front or rear wall.

The ridge height and roof pitch of the storage building's roof

The ridge height is not the same for every storage building. The ridge height depends on the eave height and the width of the storage building. The eave height is at the intersection of the wall with the roof. In the drawing below, the eave height is indicated by the yellow dot and the ridge height by a red dot. We use the term eave height because this is a term also used by municipalities in permits. The eave height and width of our storage buildings are standardized, but you do have some choices in this. The ridge height follows from these choices.

The roof pitch is the angle that the roof plane makes with the "floor" (the horizontal). The roof pitch is important for the desired usable area under the roof plane, drainage, and the appearance of the building. Our storage buildings have a low roof pitch. Roofs between 5˚ and 15˚ are considered to have a shallow pitch.

To give you an idea of some height dimensions that are possible with our storage buildings, we list some examples below. We have listed several types of storage buildings with eave and ridge heights. We have also listed the roof pitch. This is standardized and cannot be adapted to your wishes because the shape of the roof is already preformed in the frame of the storage building.

The above dimensions are for the storage building's frame. We measure the eave height in the construction, at the intersection of the column and the rafter. The cladding of the storage building is then added on top, providing an extra 3 cm for uninsulated sheet material and 7 cm for insulated sheet material.

Is it possible to let the roof of the storage building (on one side) overhang?

Our storage buildings are designed for a specific allowable snow and wind load combination. The calculation assumes that the walls and doors are closed during strong winds. By design, we can offer the storage buildings at a low cost. Extending the roof would cause the roof to catch extra wind. This additional load has not been taken into account in the strength calculations.

We hope the above information helps you make an informed decision. If you want to know exactly what the storage building of your choice costs, please fill out our quotation tool completely without obligation. You will receive a quote by email that shows you at a glance what the costs and transport costs are for your storage building. You can create multiple quotes and check different options. This way, you can compare them well.
