A roof condition report is a documented snapshot of a roof's state at a point in time. Buyers use them before purchase, sellers use them to head off renegotiation, insurers use them as evidence, and roofing contractors use them to quote accurately. The problem is that the phrase covers everything from a one-line email to a proper photographic survey.
The essentials every report should have
- Photographs of every elevation and slope — not just the defects. Context matters.
- Each defect marked on the photograph, so there is no ambiguity about where it is.
- A severity grade for each finding, separating urgent repairs from monitoring items.
- A plain-English description of each defect and what happens if it is left.
- The date of inspection and the areas covered, including any that could not be accessed.
What separates a good report from a weak one
Weak reports list defects without locations or photos, which makes them useless for quoting and easy to dispute. Good reports let a contractor price the work without revisiting the property, and let a buyer negotiate with evidence rather than opinion. Independence matters too: a report from a company that also sells repairs has an obvious conflict of interest.
When you actually need one
- Buying a home — especially older Scottish properties with slate roofs.
- Before or after a tenant's lease on a commercial property.
- After storm damage, as evidence for an insurance claim.
- Before commissioning repairs, so quotes are based on the same facts.
- Annually, to track whether a known defect is stable or worsening.
The bottom line
A roof condition report is only as useful as the evidence in it. Insist on photographs, locations, severity grades and independence — anything less is an opinion, not a report.
