Solar panels and roof lifecycle sequencing

Avoid installing new PV on a roof that will soon need replacement and document structure, attachments, membrane and future access.

VERT / GREEN

Compare roof age/condition and PV system horizon before signing.

JAUNE / YELLOW

Future removal/reinstallation cost can change project economics; attachments must transfer loads correctly.

ROUGE / RED

End-of-life roof, unknown structure, leakage or attachment changes: coordinate roofer/structure/electrical before PV.

Interactive triage

This triage helps choose the next step; it does not replace design, permitting or professional diagnosis.

Aging roof
Compare reroof-before-PV with future removal/reinstallation. Leak or questionable membrane
Repair and confirm roof condition before covering the area with PV. Unknown framing/trusses
Verify loads and attachment load path before installation. Recent documented roof
Keep photos, warranties and attachment plan.
