StormLead Pro
Help & Documentation

Everything you need to know.

Learn how to find storm-damaged roofing leads, understand risk scores, explore hail events on the map, set up alerts, and get the most out of StormLead Pro.

Getting Started

StormLead Pro helps roofing contractors find homeowners with storm-damaged roofs before the competition. It combines real NOAA radar hail data with actual property addresses to surface your highest-probability leads in seconds.

To get started, sign in — no credit card required.

1

Search a neighborhood

Enter any address and pick a radius. We pull every nearby property and check it against hail records.

2

Review risk scores

Each property gets a High / Medium / Low risk rating based on real hail size and recency.

3

Save & contact

Save your best leads, enrich them with owner contact info, then export or start outreach.

Neighborhood Scan

From the Neighborhood Scan tab, enter any address — a street address, intersection, city, or ZIP code — and choose a search radius (0.25 to 3 miles). Hit Scan Neighborhood and results appear within seconds.

Reading the results

Each property card shows the address, a color-coded risk badge, the largest recorded hail size, the most recent storm date, and the number of storm events on record. Properties are sorted highest-risk first by default.

Map view

The interactive map shows every result as a circle, color-coded by risk level — red for High, orange for Medium, yellow for Low — so you can immediately see where storm damage is concentrated. Click any circle to highlight the matching property card. Switch to Satellite view using the layer control in the top-right corner of the map.

Saving leads

Click the bookmark icon on any property card to save it to your lead list. You can save individual leads or use Select All and then Save Selected to bulk-save multiple properties at once.

Storm Explorer BETA

Storm Explorer flips the workflow. Instead of searching a specific address, you pan and zoom a full-screen map to explore storm history across any region. As you move the map, the left panel automatically updates with ranked storm clusters in the visible area.

Click the Storm Explorer tab at the top of the app to switch into this mode.

Filter bar

Four controls let you narrow what you see:

Min Hail

Show only clusters that had hail at or above this size. Range: 0.50" (pea) through 2.00" (golf ball).

Period

Lookback window for storm events: 30, 60, 90 days (default), 6 months, or 12 months.

Wind Events

Toggle to include or exclude high-wind reports alongside hail events.

Hail Reports

Overlay individual NWS spotter and SPC hail event dots on the map. See below for details.

Event list

The left panel shows ranked storm clusters — groups of hail/wind reports near the same location. Each card shows the tier (HOT / ACTIVE / MINOR), the largest hail size, peak wind speed, date, and a score from 0–100. Click any card to fly the map to that cluster.

HOT

Score ≥ 70. Significant hail — roof damage likely. Act fast.

ACTIVE

Score 40–69. Moderate event. Worth canvassing nearby.

MINOR

Score < 40. Small or older event. Low priority.

Hail Reports overlay

Toggling Hail Reports on loads individual hail event dots sourced from NWS storm spotters and the NOAA Storm Prediction Center (SPC). These are raw, un-aggregated reports — one dot per storm-spotter observation — giving you a finer-grained picture than the cluster circles alone.

A floating legend appears in the lower-left corner of the map when the overlay is active:

≥ 2.0" golf ball
≥ 1.0" quarter
< 1.0" pea / dime

Dot size scales with hail diameter so larger events are immediately visible. Hover any dot for the exact size, date, and report source.

Map layers

Use the layer control (top-right of map) to switch between Dark Street (default) and Satellite base maps. The Esri World Imagery satellite layer makes it easy to visually assess roof condition and neighborhood density before running a full Neighborhood Scan.

Risk Scores & Hail Sizes

Risk scores are calculated from three factors: the largest hail size on record for that property's location, how recently the storm occurred, and the number of separate hail events. Larger, more recent hail = higher score.

HIGH

Hail ≥ 1.0" recorded within the past year. Roof damage is likely — these leads are your best opportunity.

MEDIUM

Smaller hail or older events. Worth a call — some damage may not have been repaired yet.

LOW

Minimal or marginal hail on record. Lower priority, but still in your search area.

NWS Hail Size Reference

Hail sizes follow the National Weather Service coin comparison scale:

🟡 Pea 0.25"
🔵 Marble 0.50"
🪙 Penny 0.75"
🪙 Nickel 0.88"
🪙 Quarter 1.00"
🪙 Half Dollar 1.25"
🏓 Ping Pong 1.50"
Golf Ball 1.75"
🥚 Hen Egg 2.00"
🎾 Tennis Ball 2.50"
Baseball 2.75"
🥎 Softball 4.00"+

Saved Leads

The Saved Leads page is your working lead list. Every property you save from a search lands here. You can filter by risk level, search by address or owner name, and track each lead through your sales pipeline.

Lead statuses

Move leads through your pipeline by setting their status:

NEW Just saved — not yet contacted.
CONTACTED You've reached out by phone or email.
QUOTED An estimate has been provided.
CLOSED Job won — roof replacement scheduled or complete.
DEAD Not interested, unresponsive, or already repaired.

Notes

Each lead has a notes field. Click the notes icon on any row to add call logs, observations, or follow-up reminders. Notes auto-save.

CSV Export

Click Export CSV at the top of the Saved Leads page to download your full lead list. The export includes address, owner name, phone, email, risk level, hail size, and current status — ready to drop into any CRM or dialer.

Owner Enrichment

Enrichment pulls the property owner's name, phone number, and email address from public parcel records and data providers — so you can start outreach without manual skip tracing.

To enrich a lead, click the lightning bolt icon on any row in Saved Leads. The enrichment runs in the background and fills in the owner's contact details within a few seconds.

Data providers used

  • Regrid — public parcel data for owner name and property details (free tier: 25/day)
  • Whitepages Pro — phone and email lookup (~$0.22/record)

Enrichment data comes from public records. Availability varies by county and state.

Storm Alerts

Storm Alerts watch your territory for you. Instead of checking back every day, you define the areas you work and StormLead Pro emails you the moment qualifying hail is detected — so you can be the first roofer on the phone after a storm.

Setting up a watched area

  1. Go to Alerts in the navigation.
  2. Enter an address or city name in the Add Watch Area form.
  3. Choose a radius (5, 10, 25, or 50 miles).
  4. Set your minimum hail size threshold — alerts only fire when hail meets or exceeds this size.
  5. Click Add Watch Area. You can add multiple areas to cover your full territory.

How alerts work

StormLead Pro checks for new hail events every 30 minutes using Tomorrow.io weather data. When a hail event meets your radius and minimum size criteria, you receive an email with the storm details and a direct link to search that neighborhood for leads. Each unique storm event triggers at most one alert per watched area — no duplicate emails.

Email setup

Alerts are delivered via your own SMTP server. Contact your administrator to configure the outbound email settings. Once configured, alert emails arrive from your own domain — which also improves deliverability.

You can pause or reactivate any watched area at any time using the toggle on the Alerts page. Paused areas will not trigger emails but remain saved for when you need them.

Data Sources

NOAA SWDI — Hail history (Neighborhood Scan)

The National Weather Service Severe Weather Data Inventory contains verified NEXRAD radar hail signatures going back 10+ years. No API key required — completely free and publicly available. Note: SWDI data carries a ~90–120 day processing lag for the most recent events.

Iowa State Mesonet LSR — Hail Reports overlay

The Iowa State IEM Local Storm Reports API provides NWS storm-spotter hail observations for the US with up to 5 years of history. Used to power the individual Hail Reports dots in Storm Explorer. Free, no API key required.

NOAA SPC Hail Reports — Hail Reports overlay (recent)

The Storm Prediction Center publishes verified hail reports from the past several days as a public CSV feed. StormLead Pro merges SPC reports with LSR data, deduplicates overlapping events, and renders them as the Hail Reports overlay in Storm Explorer. Free, no API key required.

Tomorrow.io — Storm Alerts & recent hail

Powers the Storm Alerts background monitor with near-real-time storm data and fills the NOAA processing gap for very recent events in Neighborhood Scan. Free tier covers 500 requests/day.

OpenStreetMap / Overpass API — Property addresses

Real residential addresses pulled from the OpenStreetMap Overpass API. Covers the entire US with no API key or usage fees. Address density varies by region.

Regrid — Parcel & owner data

Public parcel records including owner name, property type, and year built. Free Starter plan includes 25 lookups/day.

Whitepages Pro — Phone & email lookup

Appends phone numbers and email addresses to enriched leads. Pay-per-record (~$0.22/lookup). Only called when you click the enrich button on a lead.

Google Maps — Geocoding & map display

Used for address autocomplete, geocoding (address → lat/lng), and the interactive map view in Neighborhood Scan.

Esri World Imagery / Leaflet.js — Storm Explorer map

The Storm Explorer map is built on Leaflet.js with Esri World Imagery satellite tiles and CARTO dark street tiles. Free for non-commercial use.

Frequently Asked Questions

All hail data comes from NOAA's NEXRAD radar network, NWS storm spotters, and Tomorrow.io — no estimates, no ZIP-code averages. Every risk score is based on an actual recorded hail event at or near that property's coordinates.
NOAA SWDI data (used for Neighborhood Scan) carries a ~90–120 day processing lag. For recent storms, StormLead Pro supplements NOAA with Tomorrow.io, which is updated within hours of a storm. The Storm Explorer Hail Reports overlay draws from Iowa State LSR (up to 5-year history) and the SPC feed (last few days), so it reflects events that haven't yet landed in SWDI. Storm Alerts use Tomorrow.io exclusively and fire within 30 minutes of detection.
Neighborhood Scan is address-first: you enter a specific address and we find every property nearby that was hit by hail. Storm Explorer is map-first: you pan and zoom freely to explore storm history across any region and see ranked event clusters. Use Storm Explorer to scout unfamiliar territory or find active storm corridors, then drill into a neighborhood with Neighborhood Scan to pull the actual lead list.
Each dot is an individual storm-spotter observation from the NWS Local Storm Reports network or the NOAA SPC hail feed. These are ground-truth human reports — a trained spotter found and measured an actual hailstone. Dot color and size reflect hail diameter: red/large for golf ball and above, orange/medium for quarter-size, yellow/small for pea to dime. Hover any dot for the exact size, date, and report source.
Address coverage depends on OpenStreetMap data density in that area. Rural or recently developed neighborhoods may have fewer addresses on record. You can always enter a specific address directly in the search bar even if it doesn't appear in the results list.
Yes. Click Export CSV on the Saved Leads page to download your full lead list. The CSV includes address, owner name, phone, email, risk level, hail size, year built, status, and notes — compatible with any CRM or dialer that accepts CSV import.
When you click the enrich button on a lead, StormLead Pro queries Regrid for the public parcel record (owner name, year built, property type) and then Whitepages Pro for a phone number and email address. Results appear within a few seconds. Enrichment quality depends on public record availability in that county.
Yes — and that's the point. Watched areas are territory-based, not lead-based. An alert fires the moment hail hits your watched area, even if you have zero leads there yet. It's designed to get you into a new neighborhood before you've ever worked it.
Currently unlimited. You can add as many areas as you need to cover your full territory.
Yes. Your saved leads, notes, and watched areas are tied to your account and are never visible to other users.
Any standard SMTP server works — Gmail, Outlook, or a private mail server. StormLead Pro uses STARTTLS on port 587 by default. Contact your administrator to configure the outbound email settings in the app.
