Solar Roof Structural Checklist: What a Site Visit Should Confirm
Understand the roof condition, age, materials, layout, attachments, and electrical details that a real solar site assessment should evaluate.
Quick answer
A real solar design needs more than square footage. Roof condition, structural details, usable planes, access, electrical equipment, and local requirements should be checked before a final contract price is trusted.
Roof age affects timing
If a roof may need replacement soon, removing and reinstalling panels later can add cost and delay. Discuss roof condition before finalizing panel layout and contract terms.
Usable area is smaller than roof area
Vents, skylights, ridges, shade, setbacks, and fire-access requirements can limit panel placement. An aerial image or rough home size cannot confirm the final layout.
Attachments and materials matter
Roof material, pitch, access, and structural details affect installation method. Ask who is responsible for any required structural assessment or roof repair.
Electrical work belongs in the scope
A proposal should identify electrical-panel work, conduit path, equipment location, and any excluded upgrades. These items can change both price and schedule.
