Sorting hail leads by roof age, material, and access

Start with the roof, not the storm map

After a 1.0-inch hail event, the first pass should sort roofs by replacement age, surface type, and how quickly a crew can get to them. A short list in the right order produces more usable inspections than a broad list with no structure.

This matters in mixed markets like Newark, California, Saint Peter, Illinois, Redwood City, California, Peoria, Illinois, and Fairbury, Illinois. The hail size was modest, but the roof mix is not. That changes the lead order.

NOAA storm reports and local warning-area intel give the broad path. Field routing starts with the building. A 2006 asphalt roof near the end of service life is a different lead than a 2021 standing-seam home two miles away.

Rank by roof age first

Roof age is the first filter because it changes the inspection yield. Older roofs show strike signatures faster. They also leave less room for a carrier to argue wear versus storm impact.

Use three age bands:

• 0 to 7 years
• 8 to 15 years
• 16 years and older

Put the oldest roofs at the top of the list when hail reached 1.0 inch and the area includes standard asphalt shingles. That is the simplest way to separate likely loss from low-value canvass stops.

In Peoria and Fairbury, older residential stock will usually rise to the top of the route. In Newark and Redwood City, the roof age spread is tighter in many neighborhoods, so the age filter matters less by itself. It still helps when paired with material and access.

Look for permit history, prior satellite imagery, and visible patchwork. Patchwork is a signal. So are granule wash lines, ridge repairs, and mismatched shingles. A roof with prior work should move ahead of a newer roof with no visible wear.

Material changes the order

After age, sort by roof cover.

Asphalt shingles

Asphalt remains the main target after 1.0-inch hail. It is the most likely to show bruising, displaced granules, and soft hits that do not show from the street. Start with roofs that are older, south- or west-facing, and fully exposed.

Wood shake

Wood shake requires a different approach. Hail may split fibers or open edges rather than leave obvious bruises. These roofs need experienced inspectors. If the market has limited labor, keep them in a separate lane so the crew does not lose time on false negatives.

Metal

Standing-seam and exposed-fastener metal should move lower on the first-day list unless there is obvious functional damage. Dings and coating loss are possible after 1.0-inch hail, but these jobs usually take more documentation time than asphalt claims.

Tile

Concrete and clay tile belong on a separate list. The roof can look intact from the street and still have fractured field tiles, hip damage, or broken ridge units. Access and safety matter more here than speed.

Flat and membrane roofs

Low-slope roofs should be grouped by access. If the roof is visible from the ground and reachable by ladder or stair tower, it may be efficient. If not, put it behind easier targets unless the building has clear storm-related interior water intrusion.

Use access as the third filter

Access is where many route plans break down. A roof that should be inspected can still be a poor first stop if entry is slow, gated, or requires multiple decision-makers.

Sort by:

• open drive-up access
• gated but likely reachable with prior call
• multifamily or commercial access that needs coordination
• rear-lot or alley-only access
• roof lines that require special fall protection or lift access

In Redwood City and Newark, access is often the deciding factor. Tight lots, side-yard constraints, and nearby traffic can slow even simple inspections. Put these roofs in blocks, not scattered single stops.

In Saint Peter and Fairbury, access is usually easier, but distance between targets can burn more time than the inspection itself. Group by road corridor. Keep one crew on the same side of town until the accessible roofs are cleared.

Build a three-part lead stack

A practical hail lead stack should have three tiers.

Tier 1

High-priority roofs.

• 15 years or older
• asphalt or wood shake
• easy access
• direct hail exposure on the storm path

These are the first knock, first inspection, first documentation stops.

Tier 2

Moderate-priority roofs.

• 8 to 15 years
• mixed materials
• reasonable access
• partial exposure or shielding from trees and adjacent structures

These should stay in the route, but after the first tier is cleared.

Tier 3

Lower-priority roofs.

• under 8 years
• metal, tile, or steep complexity
• difficult access
• no visible collateral clues from the street

Keep them in reserve unless field notes change the order.

Match route order to roof density

Dense subdivisions want different routing than scattered rural pockets. In a compact market, a crew can work older asphalt homes in a tight loop and stay productive. In a spread-out town, the route should cut drive time first.

That means a lower-scoring roof can move up if it sits beside a higher-value stop. One accessible roof on the same block can justify a quick second look. Two doors away from a confirmed hit, a similar roof becomes easier to inspect and easier to explain.

In Peoria, route density can support stacked canvass blocks. In Fairbury and Saint Peter, the better move is often a corridor plan that keeps the truck moving in a straight line.

Use NOAA and field reports together

NOAA storm data gives the size and location context. Field reports give roof-level sorting clues. Use both.

When NOAA shows 1.0-inch hail across a warning area, that is enough to justify a focused roof review. It is not enough to treat every address the same. The roof list still needs age, material, and access filters.

If a local report notes broken soft metals, dented gutters, or collateral damage near older subdivisions, move nearby asphalt roofs up the list. If the same storm crossed newer development with metal and tile, keep those addresses in a lower lane until the first tier is complete.

What field teams should note on the first pass

The first pass should record only what changes the next move.

• approximate roof age band
• roofing material
• visible patching or prior repair
• access issues
• tree cover or sheltering structures
• collateral clues at gutters, vents, downspouts, and window screens

Do not spend the first hour building a full file on every stop. Capture the details that change priority. A roof with clear hail-side collateral and older shingles should not sit behind a newer roof with no visible exposure.

Keep the list flexible

A hail lead list should change as crews return from the field. One documented impact on an older asphalt roof can move a nearby block up. A gated property with no response can move down. A flat roof with interior leak signs can move up even if the exterior looks quiet.

That is the practical way to sort after a 1.0-inch event in mixed markets. The storm size sets the baseline. Roof age, material, and access set the order.

In Newark, Saint Peter, Redwood City, Peoria, and Fairbury, that order is what keeps the route clean and the first-day inspection work on the right roofs.
