Costs and included work
For raising a roof ridge, compare the scope first: supporting structure, shell, roof shape and connection to the existing house. A price is useful only when supply and finishing work are clearly defined.
| Work / price basis | Starting indication | Scope |
|---|---|---|
| Raising a roof ridge | Price on request | Supporting structure, shell, roof shape and connection to the existing house |
What affects your total?
A comparable price requires a defined single- or double-sided alteration, new ridge height and structural scope. Existing foundations and walls, crane setup, stairs, services and finishes can be substantial separate items. A shell and a ready-to-use room are different scopes.
What to send with your request
Send current and proposed layouts, roof dimensions, facade photos and available structural information. Include your postcode, preferred schedule and the elements that must remain, so the scope can be assessed.
Assess the potential space
Discuss headroom, stairs, daylight and the intended use of the rooms. The existing roof geometry and structural arrangement influence the practical options.
Develop the structural and permit plan
An engineer should assess the altered loads and connections. Check the proposal in the Omgevingsloket and resolve appearance, neighbour and ownership considerations where relevant.
Price the whole alteration
Include roof work, insulation, weather protection, installations and internal finishing. Agree how the existing home will be protected during opening and reconstruction of the roof.
