Roofing Permit Data

Roofing permit data is the record of roof replacement and repair authorized at a property: tear-offs, overlays, resheeting, and the covering material installed. Builty structures these nationally and derives roof age at the address from them, dated from the permit rather than estimated from the building.

Why permits

The roof is the claim. The permit is the date.

Roof condition drives loss severity more than almost any other property variable, and it is the one carriers are least able to verify at quote. Self-reported roof age is inconsistent, assessor records are silent on it, and imagery can tell you a roof looks new without telling you when it was replaced or whether the deck was touched. A roofing permit is a dated, government-issued record of the replacement itself.

The distinctions that change how a roof should be rated.

SignalWhat it carries
Roof ageDerived at the address from the most recent roof-covering permit, dated
Tear-off vs overlayA full replacement and a second layer over the old one are not the same roof
SquaresRoof area permitted, where the jurisdiction publishes it
Covering materialArchitectural and 3-tab composition, tile, metal, wood shake, TPO and EPDM
Warranty termThe rated life named on the permit, such as a 30-year laminate
Decking & resheetStructural work under the covering, which overlay permits will not show
Coupled workSolar, gutters or skylights permitted on the same record

FAQ

Frequently asked questions

How do you determine roof age from a permit?
From the most recent roof-covering permit at the address, dated. Where no replacement has been permitted, the roof is reported as the building's own age, since a roof cannot predate the structure under it. The two cases are labeled differently rather than merged.
What is the difference between a tear-off and an overlay?
A tear-off removes the existing covering down to the deck before the new roof goes on. An overlay lays new material over the old. They carry different remaining life and different loss behavior, so they are recorded separately rather than both counted as a replacement.
Do you know the roofing material?
Where the permit names it, yes: composition, architectural laminate, tile, metal, wood shake, and commercial membranes, along with the warranty term when it is stated.
Are roofing permits public record?
Yes. Roof replacement requires a permit in most US jurisdictions, and those permits are public records published by the issuing city or county.
Can I get roofing data for one state or metro?
Yes. Any set of jurisdictions, material types, or date ranges, by API, bulk file, or ongoing feed.
