Path-Q Solar

How should I compare solar quotes that use different assumptions about roof access?

Answer

Normalize the quotes by identifying the access method each installer assumed and requesting a revised price and scope based on the same access conditions. A quote that assumes ordinary ladder access may not be comparable with one that includes scaffolding, lifts, roof protection, or extra labor.

Key points

  • Ask whether access requires a ladder, scaffolding, a lift, roof-walk protection, interior access, or temporary removal of obstacles.
  • Confirm whether permits, mobilization, traffic control, equipment rental, and roof repairs are included.
  • Compare the resulting total price, schedule, worker-safety measures, and potential roof-impact risk rather than the access line item alone.

What it depends on

  • Roof height, pitch, condition, and surrounding obstacles
  • Equipment access for delivery and installation
  • Whether the site requires special safety equipment or temporary structures

Risks and trade-offs

  • The lowest quote may rely on an access assumption that is unsafe, impractical, or likely to generate a change order.
  • More elaborate access can increase cost and installation time but may reduce damage and safety risk.

Information you may need

  • A site-specific access plan from each installer
  • A line-item list of included access equipment and labor
  • Written treatment of unforeseen access costs

Your next step

What to do next

Give each installer the same access description or site photos and request a written, apples-to-apples revision showing included and excluded access costs.
