Florida Roof Age Index

How to read this table

• Single family homes is the count of detached single family parcels the ReroofGen parcel set holds for the county. It is the denominator for every other column.
• Dated roof records counts homes whose roof has a date on record: either a finalized reroof permit, a dated government event, or an original roof confirmed by the build year age window. The second kind is an upper bound on roof age, not a confirmed install date.
• Roofs 15+ and 20+ years are counts of dated roofs at or past those ages. Below 40% coverage the dated set skews toward recent permits, so the counts are published as lower bounds and never as a share of the county.
• Median roof age is the weighted median over dated roofs and is published only for measured counties.
• A coverage gap is not an empty market. A county showing few dated roofs has not been dated yet.

Roof age by Florida county

Every figure is a count from the ReroofGen roof coverage rollup, the precomputed table the product map reads. Nothing is estimated, modeled, or extrapolated. The rollup is recomputed daily and this page is republished monthly with its as of date. A machine readable copy is served at /api/public/roof-age-index.
