Roofing & storm datasets

Free, citable, downloadable datasets for roofing and storm research. Our storm history datasets are derived from the NOAA Storm Events Database and the NWS Storm Prediction Center (SPC). Our roof statistics datasets are privacy-safe aggregates computed from measured roofs — individual properties are never shown. Every dataset is available as JSON and CSV.

Roof statistics datasets

Aggregate roof measurements — average roof area, facet count, edge lengths, and predominant pitch — by city.

Roof-measurement datasets publish automatically as coverage grows (min. 30 measured roofs per city). Check back soon, or measure a roof to help coverage along.
