Prioritizing Two Simultaneous Hail Events for Roofing Teams

At 16:12 CDT on May 14, 2026, two hail-producing cells moved into separate service markets about 180 miles apart. Both produced quarter- to near-1.5-inch hail cores within a 30-minute window. You have two inspection crews and one estimating team. Decide where to commit first.

Immediate operational checklist

Start with five quick, data-driven checks. Each takes under five minutes.

• Confirm NWS alerts for both warning areas. Note start and end times for each warning polygon.
• Pull NEXRAD hail detection and dual-polarization returns for both cores. Record estimated maximum hail size and core duration in minutes.
• Query local storm reports for any spotter-verified hail or damage within each market.
• Measure drive time and fuel roundtrip for crews from your yard to the center of each warning area using current traffic.
• Count available inspectors and estimators and assign maximum productive hours per person for the day.

Collect these five metrics before assigning crews. Record times and sources. Move to ranking.

Use radar timing to set action windows

Radar-derived timing reduces wasted travel. If a hail core passed through a town less than two hours ago, prioritize that town for same-day inspection. If a core passed more than six hours earlier, move it lower unless spotter reports indicate active damage.

Concrete rule set:

• Hail core within 0–2 hours: same-day canvass candidate.
• Hail core within 2–6 hours: same-shift follow-up if travel time is short and crew availability exists.
• Hail core older than 6 hours: schedule next-day unless verified damage reports arrive.

Example: a 45-minute hail core at 15:50 CDT over Market A is in the 0–2 hour window at 16:35. Market B saw a 20-minute core at 13:10. Market A rises in priority.

Rank markets by density and rooftop risk

Prioritize markets where a single crew can maximize inspected roofs and find the highest-risk roof types.

Scoring guidance – 0 to 10 for each factor:

• Residential density. Use census blocks or satellite imagery. 8+ favors suburbs and town neighborhoods. 3 or less favors rural markets.
• Roof exposure. Asphalt shingles with age over 7 years or older composite systems score higher. Metal and tile score lower unless field reports indicate denting.
• Commercial concentration. Flat commercial roofs with membrane coverings can show rapid, visible hail damage. Add 2 points for clusters of commercial buildings.
• Lot size and driveway access. Tight access reduces throughput per hour.

Add scores across factors. Markets with combined scores above 22 get first-run consideration.

Weigh revenue per stop and conversion velocity

Revenue matters. Use an expected average revenue per closed job and historical conversion rate by market.

• Expected revenue per closed residential job: use your own recent median. If unknown, set a conservative estimate of $6,500 for shingle full replacements and $1,200 for minor repairs.
• Expected conversion rate within 30 days: use local historical data. If absent, use 8 percent for first-visit prospects.

Multiply expected revenue by conversion rate to estimate expected revenue per inspected roof. Prioritize the market with higher expected revenue per hour after travel costs.

Example: Market A predicts $650 expected revenue per inspected roof after factoring conversion. Market B predicts $300. If Market A and B have equal travel times and damage likelihood, send crews to Market A first.

Crew allocation rules

Assign crews by role and distance. Keep one estimating team buffered for immediate signings.

• One crew per market when drive time one-way is under 90 minutes and radar timing is within 0–2 hours.
• Combine crews for a single market when expected inspection throughput exceeds six roofs per crew hour or when heavy commercial clusters need two-person inspections.
• Reserve one estimator in-region when closure velocity exceeds 5 signed jobs per 100 inspections in prior hail events.

Travel-capacity example:

• Two crews, four inspectors each. Market A drive one-way 45 minutes, Market B drive one-way 2.5 hours. Assign both crews to Market A if radar timing puts A inside 0–2 hour window and Market A score >22. If Market B has spotter-verified damage and high commercial density, split crews and send a two-person rapid-response to B while main crew canvasses A.

Split vs. focus decision tree

Use this decision tree in under two minutes.

1. Does either market have spotter-verified structural damage or local media reports? Yes -> prioritize that market.
2. Is one core inside 0–2 hour radar window while the other is older than 2 hours? Yes -> prioritize the fresher core.
3. Are travel times comparable (within 30 minutes)? Yes -> choose higher density and higher expected revenue per hour.
4. Do you have an extra mobile estimator within 60 minutes of either market? Yes -> split for short-term presence and faster closures.

If all answers are no, default to the market with the higher aggregate score from the density/roof-risk and revenue calculation.

Field tactics once on the ground

• Start at the highest-density block shown on satellite imagery. You get 4–6 inspections per hour per two-person team in dense neighborhoods.
• Photograph roof fields with timestamped images and clear bearings to the nearest street sign. Log each inspection to a simple spreadsheet in under 90 seconds.
• For roofs older than 7 years with asphalt shingle systems and visible hail strikes, mark them for expedited estimates. For metal roofs with isolated dents, log but deprioritize for immediate replacement visits.
• Capture one control photo per block of a non-damaged roof for exposure comparison.

After-action rules for same-day changes

• If new local storm reports arrive showing larger hail in a market you deprioritized, re-evaluate within 30 minutes.
• Postpone next-day routes only after you confirm radar cores and spotter reports do not indicate missed severe impacts.

Quick reference takeaways

• Use radar timing windows: 0–2 hours, 2–6 hours, >6 hours.
• Score markets on density, roof risk, commercial cluster, and access. Threshold 22+ for priority.
• Prioritize higher expected revenue per inspected roof when travel times are similar.
• Assign one estimator within regional reach when closure velocity supports it.
• Keep inspection throughput targets: 4–6 roofs per hour per two-person team in dense areas.

NOAA sources: confirm warning-area polygons with the National Weather Service and review NEXRAD hail detection and local storm reports for verified hail and spotter accounts before committing crews. Follow the five-minute operational checklist to avoid late-stage reassignments.

Use the rules above to make repeatable, defensible decisions when two hail events compete for the same limited resources. Keep records of the radar timing and spotter reports you used. Those records drive efficient reassignments later in the day.
