What this work involves
Assess the roof structure and waterproofing before choosing a green roof. Consider the weight of the complete system.
- Capacity and build-up
- Drainage and perimeter zones
- Planting and maintenance
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Compare glazing and shading as connected envelope components.
What the drawing needs to explain
Record window orientation, opening elements and existing shade. Add the main use periods so a specialist can assess the comfort question concretely.
Allow for later maintenance
Keep operating instructions and maintenance agreements for the different systems together. Record where filters and inspection points must remain accessible.
Which trade-off matters?
More glazing does not automatically call for active cooling. Compare window size, shading and use first, then assess which technical provisions are appropriate.
Cost factors for this service
Costs depend on area, roof adaptations, system and access. Ask for the scope and selected specification to be described separately.
Bring this to the discussion
Photographs of the existing situation, available drawings and your requirements for green & sedum roofs. Identify the elements that should remain.
Questions about the work
What should I discuss before arranging green & sedum roofs?
Not every flat roof is immediately suitable. Establish whether the structure, waterproofing and drainage can support the proposed system.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
