LEED Green Roof Upstand to Pitched Roof Detail CAD Drawings – DWG Download for Roof Junctions
The LEED – Green Roof Upstand to Pitched Roof Detail CAD Drawings package helps architects, facade consultants, and roofing engineers design precise, buildable junctions where a green roof meets an adjoining pitched roof. Instead of sketching this complex interface from scratch, you work with DWG-based details that show exactly how the green roof build-up connects to tiled, slated, or metal-sheeted sloping roofs. As a result, you can follow LEED-oriented best practices for durability, energy performance, moisture control, and rainwater management. Moreover, these drawings make it easier to coordinate structural, architectural, and roofing trades on sustainable projects.
What’s Inside the LEED Green Roof Upstand to Pitched Roof CAD Set?
- 2D sectional details of green roof upstands where a flat green roof abuts a pitched roof plane
- Junctions for extensive and intensive green roof build-ups against clay tiles, concrete tiles, slate, and standing-seam metal roofing
- Interface details showing upstand flashings, soakers, step flashings, counter-flashings, and saddle / cricket arrangements at the junction
- Clear indication of vegetation layer, substrate, filter layer, drainage layer, protection board, waterproofing, insulation, vapour control, and structural deck
- Continuity of air and vapour barriers where the flat roof construction meets the sloped roof build-up
- Options for warm roof and inverted roof assemblies with continuous thermal insulation at the upstand beneath the pitched roof intersection
- DWG format compatible with AutoCAD, BricsCAD, and similar CAD platforms
Why These Green Roof–Pitched Roof Junction Details Matter
Correctly detailing the junction between green roof upstands and pitched roofs is critical for waterproofing performance, thermal continuity, and long-term durability. Poorly resolved interfaces at these transitions often cause water ingress at flashings, air leakage, and cold bridges at the eaves or verge. Therefore, this drawing set gives you practical solutions that:
- Maintain continuous insulation where the green roof meets the sloped roof structure
- Carry the waterproofing membrane and flashings to the correct height and location under or behind the pitched roof covering
- Integrate root barriers, drainage, and protection layers without compromising the pitched roof detailing
- Control runoff and direct water safely towards gutters, valleys, or drainage outlets
- Support LEED-aligned strategies for durability, energy efficiency, moisture control, and stormwater performance
In addition, you can explore more green roof CAD drawings or browse all sustainable building systems available on AppisCAD for a consistent design library.
Typical Applications
- LEED-oriented projects where flat green roofs intersect with pitched roofs on the same building
- Podium or main roofs abutting townhouse, mansard, or attic roofs
- Refurbishment projects converting existing flat roofs to green roofs adjacent to traditional sloped roofs
- Roof–roof interface coordination in BIM and CAD workflows
- Tender, construction, and shop drawing packages for green roof and roofing contractors
How This CAD File Supports Your Design Workflow
This green roof upstand to pitched roof detail drawing fits smoothly into standard CAD documentation sets. Furthermore, the layers, line weights, and hatch patterns follow a logical structure, so you can quickly adjust materials to match your project specifications. Simply reference or copy the detail into your section sheets, then edit notes and dimensions to suit your local codes, roofing system, and project standards. Consequently, you gain faster coordination and a clearer technical package.
- Speeds up production of coordinated flat-to-pitched roof junction details
- Reduces design risk at critical waterproofing and roof interface locations
- Provides a clear communication tool between architect, structural engineer, roofing designer, and contractor
