Example: Replacement planning with ventilation constraints
Example case focused on defining scope for an aging roof where attic access and existing vent paths limited available options.
Conditions
- Shingle wear near end of service life
- Limited attic access for intake evaluation
- Flashing transitions with mixed material types
Scope decisions
- Define replacement scope with optional ventilation paths (when feasible)
- Specify underlayment and water-shedding layers by roof geometry
- Detail edge and flashing requirements as line items (required vs optional)
Outcome (neutral)
- Scope options documented for decision-making
- Ventilation choices clarified with constraints noted
- Scheduling and materials framed as availability-dependent
