Path-Q Solar
How should I decide whether to request solar quotes now or wait for a planned roof redesign?
Answer
Wait for the roof redesign when it is likely to change roof planes, structure, shading, access, or the intended installation timing; otherwise, obtain preliminary quotes now but label them as conditional. A final solar design should use the roof configuration that will actually exist when the array is installed.
Key points
- Roof work before solar can avoid removing and reinstalling panels and may clarify structural capacity and waterproofing responsibility.
- Early quotes can help with budgeting and coordination but may not be comparable to post-redesign proposals.
- Ask installers to identify assumptions about roof shape, usable area, structural work, and electrical routing.
What it depends on
- Timing and certainty of the roof redesign
- Whether the redesign changes orientation, area, pitch, or shading
- Roof condition and remaining service life
- Desired solar installation schedule
Risks and trade-offs
- Waiting may delay savings or expose the project to changed equipment or financing conditions.
- Installing before redesign can create rework, warranty disputes, and avoidable roof penetrations.
Information you may need
- Roof redesign plans and schedule
- Roof age, condition, and structural information
- Desired solar capacity and timing
- Whether roof and solar contractors will coordinate warranties
Your next step
What to do next
Ask two installers to price a preliminary design based on the proposed roof changes and identify which assumptions must be finalized before a binding quote.
