Having a roof terrace designed and engineered
A roof terrace is a wonderful way to create extra outdoor space. Especially for homes without a garden, balcony, or sufficient outdoor area, a roof terrace can add significant living comfort. However, a roof is not automatically suitable for use as a terrace.
A roof terrace introduces extra load from people, decking, tiles, furniture, planters, and railings. Therefore, a structural assessment or structural calculation is often necessary. Constructieplan.nl verifies whether your roof is suitable and details what is required for a safe execution and a complete building permit application.
Why choose a roof terrace?
A roof terrace increases the utility value of your home. You create a place to sit outside, relax, or add extra living space to an upper floor.
Structurally, a roof terrace is a sensitive project. A roof that was originally only intended as a roof structure must suddenly be capable of supporting a live load. Balustrades, access, privacy, water drainage, and roof penetrations must also be carefully taken into account.
With a proper architectural drawing, structural calculation, and working drawing, you can be certain whether the roof can handle the load and which modifications may be necessary. This prevents dangerous situations, damage, and unexpected costs during execution.
What do you need?
For a roof terrace, you typically need:
- Architectural drawing of the existing and new situation
- Structural calculation of the roof, joist structure, floor, or load-bearing structure
- Structural drawing of any required reinforcements
- Drawing of the balustrade, access, and railing
- Detail drawings for watertight connections
- Working drawing for the contractor or roofer
- A building permit application with the municipality
A roof terrace often requires a building permit, partly due to safety, privacy, sightlines, and the impact on the surroundings. Therefore, it is important to have a thorough check done beforehand to determine which documents are required.
What are the costs?
The costs for a roof terrace highly depend on the existing roof structure and the desired execution. A sturdy flat roof usually requires less investigation and calculation work than an older roof that needs to be reinforced. The access, balustrade, finishing, and permit requirements also influence the costs.
Roughly speaking, you should take into account costs for architectural drawings, structural calculations, structural drawings, working drawings, and permit application management. Because a roof terrace requires a precise structural assessment, proper preparation is essential.
