Why roofing permits are good leads
Reroofing is one of the most frequently permitted jobs in American cities. Every new roofing permit tells you that a property owner has already decided to spend money on the building envelope. That matters to more than roofers: gutter installers, skylight and solar companies, insulation contractors, material suppliers and dumpster rental firms all follow roofing activity. Roofing permits also cluster after storms, so watching where they appear is a cheap way to see which neighbourhoods are in a replacement cycle.
The difference between a permit and a normal lead list is timing and intent. A purchased list tells you who might need something one day. A permit tells you that somebody has already filed paperwork with the city, usually with a date, an address and often a value and contractor. You are not guessing.

How to use the data, step by step
- Use the roofing filter and zoom to the ZIP codes you serve. Clusters of permits on the same streets usually mean hail or wind damage, and neighbours who have not filed yet are often next.
- Check the valuation where it is published. A high value usually means full tear-off and new decking, a low value a repair.
- Solar installers should watch reroofs closely: a fresh roof is the best moment to add panels.
- Suppliers can count permits per contractor to see who is growing and who to visit first.
A practical routine for roofing contractors: every Monday, open the map for your service area, filter to the last seven days, export or note the new addresses, and plan visits, letters or calls. The work takes fifteen minutes, and because the same data is not on your competitors' desks, the conversations start earlier.
What a permit record contains
Fields differ by city, but most records include the permit type and description, the date filed or issued, the address and coordinates, and the status. Many cities also publish the estimated value of the work and the contractor name; Chicago, Orlando, Marin County and several others publish contractors for most records. Mapenzo normalises these sources into one map and one set of trade filters, so you do not need to learn fourteen different city portals.
Be aware of the limits. Mapenzo only shows what the city publishes, and some cities classify work types loosely, so a small share of records may sit under a broader category such as mechanical or alterations. When in doubt, read the original description, which is always shown on the permit card.
