Steel Roof Framing
Structural layouts for steel beams, rafters, joists, purlins and secondary framing, coordinated with gridlines and supports.
Structural Design & Documentation
Roof Structure Design & Framing Drawings
Roof structural design and drafting support for steel and timber framing systems, including trusses, rafters, purlins, bracing, support connections and coordinated drawing packages.
- Roof framing layouts
- Member & connection details
- Engineer-led design coordination
Typical structural framing relationships. Actual member sizes, spacing and connections require project-specific design and approval.
Service Coverage
Roof Structural Systems We Help Document
Scope is defined by the approved design criteria, structural system, building geometry and required drawing stage.
Timber & Wood Trusses
Truss positioning plans, support locations, member identification and coordination with approved truss design information.
Roof Trusses & Bracing
Truss configurations, cross bracing, lateral restraint locations and framing relationships as specified by the engineer.
Purlins, Joists & Deck
Purlin spacing, joist layouts and roof deck support details with architectural roof profiles and penetrations.
Connections & Supports
Connection drafting for seats, base plates, bearing positions and interfaces with the supporting structural frame.
Complex Roof Geometry
Hip, gable, mono-pitch and multi-level roof structures, including geometry transitions and drainage coordination points.
Engineering Coordination
Design Inputs That Shape Roof Framing
Roof design is based on more than the architectural roofline. A coordinated package needs documented loads, structural support conditions and applicable design requirements.
- Dead, live, wind, snow, uplift and other project-specific load cases
- Span lengths, roof slope, elevations and supporting grid arrangement
- Member material, connection assumptions and serviceability criteria
- Lateral stability, roof diaphragm and bracing requirements
- Openings, rooftop equipment, drainage and building-envelope interfaces
Drawing Deliverables
Documentation for Review & Coordination
We support the preparation and refinement of roof structure documentation suitable for the agreed design and detailing stage.
- Roof structural framing plans and gridline references
- Truss, rafter, purlin and joist layouts
- Roof sections, elevations and typical details
- Bracing layouts and support condition details
- Structural member and connection schedules where specified
- CAD revisions, drawing markups and coordination documentation
Project-Level Coordination
Interfaces with architectural roof geometry, MEP openings, cladding supports and structural supports are checked against the supplied coordination information.
Fabrication or erection instructions are included only where agreed and supported by approved engineering information.
Our Documentation Process
From Project Inputs to Reviewed Drawings
Review Inputs
Confirm issued drawings, roof geometry, structural criteria, scope boundaries and deliverable format.
Develop Layouts
Prepare framing plans, truss and purlin positions, member references and initial details.
Coordinate & Revise
Resolve documented interfaces, incorporate authorized markups and track drawing revisions.
Quality Review
Check drawing consistency and issue the agreed documentation for client/engineer review.
Frequently Asked Questions
Roof Structural Design FAQs
Do you support both steel and timber roof structures?
Yes, the drafting scope can address steel roof framing and timber roof systems, subject to project details and available engineer-approved design information.
What documents are needed to begin roof framing drawings?
Typically architectural roof plans, elevations, grids, sections, structural criteria, relevant calculations or design drawings, specifications and any available coordination files.
Can roof designs be coordinated with MEP penetrations and rooftop equipment?
Yes. Openings, equipment loads and supporting interfaces can be identified and reflected in coordinated drawings. Any required structural redesign must be approved by the responsible engineer.
Are your drafting drawings a substitute for engineer-approved structural design?
No. Drafting and detailing document the agreed design. Structural analysis, code compliance, member sizing and final design approvals remain with the authorized engineering professionals.
