Dataset

The roof cost dataset

Every modelled range on this site — 110 cities × 10 materials — as open data. Each row carries its labour factor, source and checked-on date. These are modelled estimates (see methodology), not quotes or surveyed prices.

CSV

Download costs.csv — one row per city × material.

JSON

Download costs.json — same data, structured.

Terms of reuse

Free to reuse with attribution to RoofCostLookup and a link to the methodology page, provided the "modelled estimate" labelling travels with the numbers. Stripping the estimate labelling is the one use we ask you not to make.
