Annual B.C. roofing cost index
A useful roofing cost index tracks change in comparable completed estimates or contracts, not a mixture of unrelated totals. No 2026 index value should be published until the anonymized dataset and calculation method are approved. The decision should also account for number of comparable records.
Normalize the records
Separate residential replacement, repair, metal and low-slope work. Compare like scopes using area, material and tax treatment.
Choose a transparent base
State the base year, weighting, inclusion rules and whether the index reflects quoted, accepted or completed work.
Protect customer information
Remove names, exact addresses and details that could identify a property. Publish only aggregated results with a minimum sample threshold.
Details worth checking
- Base year and index formula
- Number of comparable records
- Material and project categories
- Regional weighting
- Tax and change-order treatment
