Companion-item checklist

The edge and add-on lines: starter course, ridge cap, drip edge, pipe jacks and flashings, valley liner, ice-and-water shield where code requires it, and the steep- and height-charges on anything over 7/12 or above one story. Estimates written from an aerial without slope detail drop steep charges constantly. Debris removal and detach-and-reset items (satellite dishes, gutters for fascia work) round out the usual suspects. The wind checklist in this tool lists them with reasons.

Alongside extraction and drying equipment: antimicrobial application, equipment setup and monitoring visits, content manipulation to move furniture, and the tear-out's paired rebuild — drywall hang/tape/float, insulation, baseboard. Carpet losses add pad and tack strip, which are missed so often they're standing checklist items. If the home is occupied, dust protection and scheduling premiums apply. Run the water checklist, then paste the actual estimate into Scope Check to see which items are genuinely absent.

Because primary scope is what's visible and companion scope is what's implied. The wet drywall is in the photo; the antimicrobial, the monitoring visits, and the baseboard that comes off with it are inferences from how the work actually gets done. Time pressure and template reuse make it worse. A peril-specific checklist converts those inferences into named line items — and an automated pass like Scope Check catches whatever the human pass still missed.
