the raw page is mirrored to R2). 2 of the 4 named sources that could be read published a usable figure; 2 published none and are recorded as not published, never filled in; 0 could not be read (blocked, dead or unreachable) and count nowhere. The headline figures (median, minimum, maximum, quartiles) are over ONE figure per source for each breakdown it prices, in % (a source's median where its page yielded several accepted sentences for one breakdown), so a page that gives figures for several breakdowns gives one for each and N counts 3 figures, never sentences; 117 candidate sentence(s) were refused by a reviewer with the reason recorded. The fuller derivation this dataset is chartered to grow into (not yet what the figures above are; they are each source's own published figure as read): the official monthly material price indices for exactly the components an industrial roof is made of - fabricated structural steel, coated steel sheet, insulating materials - carried forward each month and differenced against the same month a year earlier, then indexed against this site's own median published installed rate per system, so the page can say whether contractors' quoted rates are moving with the material indices or away from them. The statistical agency publishes the index; nobody joins it to what roofers actually quote.", "embed": "
