A proper report should contain: Cover page, executive summary, area-by-area findings, photos, recommendations, and a closing statement.
Typical sections include exterior roof surface, roof framing, flashing and penetrations, drainage and gutters, attic space and ventilation, insulation, moisture indicators, and structural concerns.
Documentation should include: Date of inspection, inspector license number, company name, contact details, and signature or digital signature.
Each section should note the condition, evidence, severity, recommended actions, and a plausible timeline for remediation.
Inspectors should describe what was examined, how deficiencies were verified, and the basis for any cost estimates or timeframes.
