How Roofing Contractors Use Building Permit Data to Find Leads
Roofing is one of the purest permit-driven trades. Every substantial roof job — a full re-roof, a roof-deck replacement on a new build, a tear-off after hail damage — requires a building permit. That permit shows up in the city's open-data feed as soon as it's filed. Which means roofing contractors who watch permit data are seeing leads that don't exist on Angi or HomeAdvisor yet.
The three kinds of roofing permits you want to see
Re-roof permits. A homeowner who pulls a re-roof permit has already committed. They've paid the permit fee, they've filed paperwork, they're planning to do this job. If you get in front of them while they're still collecting bids — not after they've signed with someone — your odds of winning are much higher than a cold lead from a platform.
Roof permits after a hailstorm. Hail runs the roofing business. After a significant storm, insurance claims drive a surge of re-roof permits over the next 30-60 days. Watching the permit feed for your market is the cleanest way to see the hail response before your competitors do. Every re-roof permit filed in a ZIP code hit by a storm is, statistically, a lead.
New-construction roof deck permits. In most cities, new builds pull a separate roofing permit once framing is done. That's your signal to contact the GC (named on the permit) and bid the roof. Production builders do roofing in-house; custom builds almost always sub it out.
What the permit actually tells you
A well-indexed permit feed gives you the job address, the permit type (re-roof vs new build), the project value (a proxy for square footage and complexity), the owner or contractor of record, and the filing date. Often you'll also get the city's permit subtype — "composition shingle," "metal roof," "tile roof" — which helps you filter to the jobs that match your capabilities.
What you don't get from a permit: a pre-qualified homeowner who's already shopping. You do the outreach. But because you're one of the first (and often the only) contractors to reach out with a prepared bid, conversion dwarfs shared-lead platforms.
The operational playbook
- Subscribe to the permit feed for the metros you serve.
- Filter by trade = "Roofing" and permit type containing "roof" or "re-roof."
- Every morning, get the list of new roofing permits filed in the last 24 hours.
- For each one, look up the owner on the county assessor and reach out within 48 hours.
- Track which permits convert, by neighborhood, by permit type, by owner type.
Within 60 days you'll have a clear picture of which neighborhoods are producing your best-converting leads and can double down on those areas.
