Professional Practice, Communication, and Documentation
This domain tests the business side of installation: written scope, change orders, homeowner communication, and records that support warranty and liability positions.
Core rules
- Put the scope in writing: shingle product, underlayment, flashing, ventilation, deck repair allowances, exclusions, and cleanup. State what happens if hidden damage is found.
- Use written change orders before installing upgraded underlayment, new decking, or added ventilation. Verbal approvals are hard to prove.
- Photograph before, during, and after: deck condition, flashing details, nail pattern, labels, and completed work. Keep daily logs and material receipts.
- Communicate schedule, access, noise, and safety expectations. Register the manufacturer’s warranty and give the owner closeout documents, including maintenance guidance.
- Do not promise a warranty outcome you do not control; report code or safety concerns in writing.
Worked example
A homeowner asks the crew to cover soft decking because it is only a small area. The installer photographs the rot, measures the area, and issues a change order for replacement before shingles go on. If the crew simply covers it, the shingle manufacturer may deny a later claim and the contractor owns the defect. The written change order protects both parties and documents the decision.
Traps
Relying on verbal changes, skipping photos of existing damage, promising lifetime coverage loosely, and failing to document manufacturer requirements are common errors.
