Roof Reporting and Standards of Practice
Domain 4 tests the Standards of Practice, report language, limitations, and exclusions. The exam checks whether you can describe what you inspected, what you did not inspect, and what the client should do next, without overstepping into code compliance or engineering.
SOP scope
Under the InterNACHI Standards of Practice, the inspector shall inspect the roof covering, roof drainage systems, flashings, skylights, chimneys, and roof penetrations, and report signs of active roof leaks. The report should describe the roof covering materials and identify observed deficiencies.
Limitations and exclusions
The inspector is not required to walk on the roof, predict remaining service life, inspect concealed areas, determine the adequacy of structural support, inspect underground drainage, or verify code compliance. When access is limited by snow, height, pitch, or weather, say so in the report.
Report language
Write what you saw, where you saw it, and what it means. Use neutral terms: 'observed,' 'not inspected,' 'recommend further evaluation by a qualified roofing contractor.' Avoid 'pass/fail,' guarantees, and unsupported cost estimates.
Worked example
You observe a sagging rear roof slope. The SOP does not require structural analysis. A defensible report entry is: 'Sagging observed at the rear slope; cause not determined; recommend evaluation by a licensed roofing contractor or structural engineer.' Saying 'the roof will collapse' or 'replacement is required' goes beyond the observed evidence.
Traps
Do not promise a remaining life expectancy. Do not label cosmetic wear as a defect without explanation. Do not omit access limitations. Do not use alarming language that is not supported by photos and notes.
