Exterior measurements — roof and walls

Wenn Property automatically retrieves exterior measurements for most Norwegian addresses. When the project has a registered address, you get access to roof faces, wall surfaces and areas — ready to use for estimating and project planning.

How it works

The data is retrieved automatically from public registries based on the project's address. You'll find all exterior information under «Utside» (Exterior) → «Bygning» (Building) in the left navigation.

You can switch between 2D and 3D view with the buttons at the bottom of the main window to see the building from different perspectives.

Roof faces

Under «Bygning» (Building) → «Takflater» (Roof faces) you'll find each individual roof face with the following data:

Area — the size of the roof face in square metres
Pitch — the roof angle in degrees
Orientation — compass orientation in degrees

Tap a roof face in the list to highlight it in the 3D model. A summary with the total roof area and number of roof faces is shown when you select the «Bygning» (Building) level.

Roof edges

Every roof edge has a type and a length. The types include ridge, hip, valley, eave, verge and wall abutment.

Wenn Property adds up the running metres for each type: per roof face, per building and for the whole property.

If an edge has the wrong type, you can change it yourself. The change is carried over to the report.

Exterior walls

Under «Bygning» (Building) → «Vegger» (Walls) you'll find all wall surfaces with:

Area — the wall surface size in square metres

This data makes it easy to calculate exterior area for facade work, painting, cladding and other maintenance.

Leave out what shouldn't be included

«Not a roof surface» — mark faces that aren't roof, for example a terrace or a staircase. They are left out of the count.
Leave out — remove roof faces, walls or whole buildings that aren't part of the job. All figures, exports and the PDF then cover only what is left.

Example: Pricing only the houses in a housing cooperative, not the garages? Leave out the garages, and the figures cover only the houses.

On the web and in the app

Roof edges, «Not a roof surface» and leaving out are available both in the browser and in WP Befaring on iPhone, iPad and Android. See Roof measurements in the app – edges, leaving out and summing.

Good to know

The feature requires the project to have a registered address
The data is available for most Norwegian addresses
Area calculations may deviate somewhat from reality — we always recommend taking control measurements
If no buildings are found at the address, the message «Ingen bygninger funnet» (No buildings found) is shown
