Patio roofs in Sevelen
Timber patio roofs in Sevelen for seating areas, terraces, entrances and canopies. We clarify use, roof cover, drainage and permit questions early, before building starts.

Direct answer
A patio roof in Sevelen makes sense when a seating area, terrace, entrance zone or garden spot should become easier to use. We build attached terrace roofs, freestanding seating covers, canopies and pergola-like timber structures, matching roof cover, foundations and drainage to the existing building and local constraints.
At a glance
Use cases
For terraces, seating areas, entrance zones or free-standing garden spots - wherever weather protection, more usable days and a clean structure matter.
Structure & roof cover
The structure can be attached to the facade or free-standing. Roof cover is chosen by use case, light, upkeep and the existing building.
Price logic
Cost depends mainly on span, roof cover, foundations, drainage and visible timber quality. After photos and site measure, we give a realistic range.
Installation & details
We start with site measure, use case, permits and rainwater routing. After that comes workshop prefabrication and a short, clean installation with defined junction details.
Which roof fits which outdoor area in Sevelen?
Use, facade situation, connection detail and drainage matter more than the search term alone.
Attached to the house
The standard option for terraces and seating areas directly at the facade. In Sevelen, facade change, wall connection and the visible water path become early planning topics.
Freestanding in the garden
Useful when the sheltered spot should sit away from the house. Foundations, boundary distance and discharge route across the plot become more important.
Canopy / entrance area
For front doors, side entrances or smaller transitions. Projection logic, drip edge and facade presentation matter more here than roof size.
Pergola / open weather cover
Best when shade, openness and a lighter look matter more than fully dense weather protection. Roof cover and permit logic still need to fit the real use.
Roof cover in Sevelen by use, daylight and upkeep
Roof cover changes not only light and maintenance, but also roof pitch, permit presentation and the water path at the existing building.
Trapezoidal sheet metal
Robust and cost-conscious for weather-focused roofs, compact canopies and practical seating-area covers.
Corrugated or profiled sheets
A practical light or weather solution for simpler roof shapes and lighter secondary roofs. Drainage still needs a clear route.
Polycarbonate
Useful when a bright covered area is wanted with lower roof weight. Low weight helps on lighter structures.
Acrylic
A more transparent solution where UV stability matters strongly. Edge details and upkeep still need the same care.
What should be clarified early in Sevelen
For a patio roof in Sevelen, span and material are only part of the job. Classification, distances, facade change and filing documents matter just as much.
The local building office is the right first contact when it is unclear whether a project is treated as a projection, an extension or an accessory structure, and whether a permit filing is required.
The municipal regulation gives orientation through Art. 25 and Art. 26 for accessory buildings, projections, height and setbacks. Site plan, sections, facades and drainage documents should be prepared early.
- Check classification, setbacks and facade change early
- Do not treat canopies and accessory structures as the same category
- Prepare site plan, sections, facades and drainage early
- Show edge details and water path in the permit logic

Drainage for patio roofs in Sevelen
A gutter and a downpipe are not enough as a planning promise. The discharge path must fit the site and the local drainage framework.
The municipal drainage documents prioritise infiltration through the ground for terraces and seating areas where technically possible. Where infiltration is intended, enough soil and humus depth should be considered early.
For retrofit roofs at existing buildings, roof pitch, gutter, downpipe, adjacent surface and wall connection together decide how cleanly rainwater can be routed.
- Test ground infiltration first where possible
- Plan for at least 30 cm of humus where infiltration is intended
- Do not plan underground infiltration systems without permit clarification
- Treat gutter, downpipe, paving and facade connection as one water path

Common questions
Do I always need a permit for a patio roof in Sevelen?
Not automatically. It depends on size, construction type and how the project is classified. Especially where the facade changes, early clarification with the local building office is advisable.
Which documents are typically required in Sevelen?
As orientation, the local regulation points to a site plan with distances, floor plans, sections, facades and drainage information. If the facade changes, the affected facade should be shown completely.
What counts more as a projection and what more as an accessory structure in Sevelen?
Smaller canopies and projecting roof elements can fall more into the logic of projections, while larger and more self-contained structures are more likely treated like extensions or accessory buildings. The binding classification always depends on the exact filing.
How is rainwater from terraces and seating areas usually handled in Sevelen?
The local guidance prioritises infiltration through the ground where technically possible. Where infiltration is planned, soil buildup and humus depth matter. If that is not feasible, the discharge path has to be coordinated properly; underground infiltration systems require permit clarification.
Which solution is more suitable in Sevelen: attached roof, canopy or pergola?
An attached terrace roof suits a seating area that should stay usable in wet weather. A canopy is stronger for entrance zones and smaller transitions. A pergola fits a more open kind of weather cover. Connection detail, drainage and use decide the right choice.
Do you have references directly from Sevelen or nearby?
Yes. We show one direct Sevelen project and nearby references from Wangs and Oberriet that are relevant for attached seating-area roofs and retrofit connections.
Quick request
A photo of the seating area, facade and connection zone is often enough for a first assessment. We then clarify which structure, roof cover and permit check fit the building in Sevelen.
