Make a roof-space observation record before choosing work
Keep dates, locations and evidence separate from a diagnosis.
Observation
Review air leakage and roof ventilation together
Understand why adding vents does not automatically resolve moisture.
Building relationships
Build a net-free-area record from actual product specifications
Keep roof area, vent net-free area and entered ratio assumptions distinct.
Tools
Discuss intake, exhaust and the paths between them
Separate product area from the physical roof-space arrangement.
Roof anatomy
Keep bathroom and kitchen exhaust distinct from roof ventilation
Record equipment and termination questions for the responsible review.
Building relationships
Prepare a condensation question record
Preserve seasonal context without calculating a remote diagnosis.
Observation
Record ice and snow patterns without choosing a remedy remotely
Connect weather observations with a coordinated envelope review.
Observation
Coordinate ventilation questions with reroofing
Keep the weather boundary, product specifications and roof-space questions connected.
Project scope
Plan access and suspect-material assessment before roof-space work
Keep investigation needs separate from permission to enter or disturb.
Project scope
Compare roof-ventilation proposals by evidence and scope
Use the same assumptions and entered amounts across proposals.
Quotes
Close out roof-space work with a useful follow-up record
Keep products, findings and later observations traceable.
