How to read a hail map before sending out your roofing team
A hail map helps you choose where to inspect after a storm. Before you assign streets, check which event the map shows, what the colors represent and where your properties sit within the estimated hail area. Those details give your team a better starting point than a report that hail fell somewhere in town.
Check the date and the data layer
Start with the selected storm date or time range. If several storms passed through the same neighborhood, look at each event separately. A map combining several days can be useful for reviewing an area's history, but you need to know which event you are discussing with a homeowner.
Read the legend before comparing streets. A shaded hail swath and an individual detection marker may represent different data. For example, MESH means Maximum Estimated Size of Hail. It is a radar-derived estimate, not a measurement collected at the house. NOAA explains how radar is used to estimate hail in its hail detection overview.
Keep that distinction in your notes. If the map gives an estimate of 1.5 inches, record it as an estimate rather than saying that 1.5-inch hail was measured at the property.
Look at the properties within the mapped area
Zoom in far enough to check the address and the surrounding streets. Confirm that the property marker is in the right place, especially on large lots or near the edge of the mapped area.
Use the estimated hail sizes to help prioritize your review, then account for what your team already knows: existing customers, scheduled inspections, previous visits and access to the neighborhood. The highest value on the map is one piece of that decision.
Avoid treating the edge of a shaded area as a precise boundary between damaged and undamaged roofs. The map estimates weather conditions. It does not establish the condition of an individual roof.
Give each rep a workable assignment
Once you have selected an area, assign streets based on the time available and the number of properties a rep can reasonably cover. Leave room for conversations, inspections and callbacks. A fixed number of streets will not work equally well in a dense subdivision and a neighborhood with long driveways.
Include the storm date and the source of the hail estimate with the assignment. Reps should also be able to see prior visits and planned follow-ups so they can explain why they are there and avoid repeating a teammate's work.
As inspection results come in, use them to reconsider the day's priorities. Record what was found, including inspections where no storm damage was identified.
Keep the weather report with the inspection record
Save the relevant weather report with the property's dated inspection notes and photos. Identify which information came from radar and which came from the inspection. This makes the file easier to understand when a homeowner or adjuster reviews it later.
