Rooftop Solar Structural Assessment

Review available drawings and site information to understand how the roof and supporting structure may respond to additional solar dead, maintenance and wind loads.

Why the detail matters

Start with the real project conditions.

Existing buildings vary in original design, condition and available records. The assessment should account for what is known about the roof, its supporting system, proposed mounting and anchorage, and the limitations of the information available.

The first review should establish what information is available, what assumptions are proposed and which decisions the work must support. Any limitations that affect the conclusions should be recorded before the deliverable is used by the wider team.

Scope and inputs

What helps us assess the work?

The required information changes by service. These are useful starting points; the final input list should match the actual project.

01

Project context

Site location, project type, current stage, intended use and the decision or outcome needed.

02

Technical inputs

Available drawings, loading criteria, equipment data, surveys or geotechnical information where relevant.

03

Clear boundaries

Agreed deliverables, assumptions, exclusions, review responsibilities, revisions and timing.

Good questions to ask

Questions about rooftop solar structural assessment

Practical answers about the inputs, limitations and deliverables that matter for this kind of work.

What should be shared for a rooftop assessment?

Existing structural or architectural drawings, roof type, building age if known, available condition photographs, solar layout and module/mounting details are useful. Site inspection or measurement may be needed if records do not reflect the actual building.

Can a roof be approved from photographs alone?

Photographs can help identify visible concerns, but usually cannot establish the capacity of the entire load path. The review method should reflect the quality of records, condition information and project-specific requirements.

Which extra loads need to be considered?

The assessment should consider the proposed system's permanent weight, relevant maintenance loads, wind effects and any other equipment loads applicable to the project. The design basis must be agreed for the actual installation.

What if original building drawings are missing?

That is common in existing buildings, but it creates uncertainty. Available records, measured dimensions, inspection findings and any necessary testing should be reviewed to decide what conclusions can reasonably be made.
