Which address to link to
- To link to the index, use /pergola-price-index/. That address does not change and always shows the latest edition.
- This page stays at
/pergola-price-index/data/and lists every edition’s files. Use it when you need the data itself. - Each edition has its own dated address, such as
/pergola-price-index/2026-q4/, and its files sit under it. An edition is frozen once published, so those addresses and files do not change. Cite a figure from the edition it came from. - The index is quarterly. A new edition adds a row to the table above; nothing is overwritten.
What is in the file
One long-format table. The first line is the header row. Values are US dollars per square foot of covered area, except the “typical price at size” rows, which are US dollars. These are advertised kit prices on the day of capture, before tax, shipping and installation. They are not transaction prices.
| Column | Meaning |
|---|---|
table | Which summary table the row belongs to. |
row | Roof category, or category plus product family. |
size_or_band | Size (for example 10x10) or size band. Blank for category-level rows. |
median | Median value: dollars per square foot, or dollars for "typical price at size". |
p25 | 25th percentile. |
p75 | 75th percentile. |
min | Lowest observed value. |

companies | Number of companies behind the row. |
families | Number of product families behind the row. |
price_points | Number of individual prices behind the row. |
label | Notes: limited sample, why a median is not published, or the benchmark gap. |
How the index is built explains which prices and products count and how the medians are calculated.
