Indiana
Supplements written for Indiana roofs, hail, derecho, and the freeze-thaw winter
Indiana takes it from every direction: statewide hail in the warm months, straight-line derecho wind that can cross a dozen counties in one pass, and a winter freeze-thaw cycle that works water back under a shingle field long after the storm season is over. One state, three separate damage mechanisms, and a carrier estimate that usually accounts for only the one that was easiest to photograph.
By Kyle Hamrick, Founder
The Estimate Company writes Indiana files from a nationwide desk. There is no claim that this office has stood on a specific Indiana roof, and there does not need to be. What decides a supplement is code mechanism, carrier behavior, and claim pattern, and those get sourced and confirmed for the address rather than asserted from memory.
The Estimate Company is run by a licensed independent insurance adjuster, with claims experience across many states, writing for contractors nationwide. What we bring to a Indiana file is code mechanism, carrier behavior, and claim pattern, confirmed for the address rather than assumed from a statewide rule.

What actually damages roofs in Indiana, and what it does to the estimate
Central Indiana: hail and the Indianapolis corridor
Marion County and the ring of surrounding counties sit under a spring and summer hail track that produces claim volume in bursts, one storm cell rolling through Indianapolis and the surrounding townships and generating hundreds of claims by nightfall. That volume is exactly why the first estimate comes back thin. A catastrophe team working a heavy file count defaults to a squares number with a shingle line, and it skips the ridge system, the soft metal evidence, and the collateral hits on gutters and vents that make the difference between a denied claim and an approved replacement.
Older Indianapolis-area housing stock also complicates the deck question, because board sheathing under an aging shingle roof does not hold a modern fastening schedule once it is exposed at tear off, and that condition is invisible until the old covering is off the house.
Northern Indiana: Fort Wayne, South Bend, and the derecho corridor
Northwest and north central Indiana sit in a corridor that produces long-line straight-line wind events, the kind that can put damaging gusts across a dozen counties in a single afternoon rather than a narrow tornado track. That signature matters on the estimate: instead of one severely damaged block, you get a wide band of creased shingles, broken seal strips, and displaced ridge cap spread across an entire region, and a carrier processing high volume prices that as routine wind rather than opening the full assembly.
The same northern counties run the state's hardest freeze-thaw winters. Repeated freeze and melt cycles work fasteners loose, split sealant at flashing laps, and drive meltwater back up under the eave course when an afternoon thaw refreezes overnight. None of that reads as storm damage, so a supplement written for the summer hail claim alone misses the ice-related loss sitting underneath it. The roof claim inspection checklist is the field sequence that documents both mechanisms before the adjuster ever arrives, because neither survives the tear off.
Southern Indiana: Evansville, Terre Haute, and the Ohio Valley
Evansville and the southwestern counties sit in the path of storm systems tracking up from the Ohio Valley, and that exposure includes tornado activity in addition to hail and straight-line wind. A single severe weather event down here can carry all three damage types on the same roof, and an estimate that treats it as a single peril hands the carrier the cheapest of the three to price from.
Terre Haute and the Wabash Valley run a similar mixed-peril pattern on a smaller scale, and the housing stock skews older, which means the decking and fastening questions that come up in Indianapolis show up here too, just on a market carriers pay less attention to by default.
Three code arguments that move Indiana files
One statewide residential code, local enforcement still applies
Indiana adopts its residential code at the state level through the Fire Prevention and Building Safety Commission rather than leaving adoption to individual cities, which means the code edition itself does not shift by municipality the way it does in a locally-adopted state. Enforcement, permitting, and any local amendment still run through the authority having jurisdiction for that address, so the AHJ gets confirmed before anything goes into a citation. Verify with local building dept Confirm the enforcing department and any local amendment for the address before the citation ships.
The repair threshold that turns a patch into a full replacement
675 IAC 14-4.4 carries a repair threshold, and once a roof section crosses it the code no longer allows a match-to-existing patch, the full slope has to meet current requirements. That threshold line is typically the single largest recovery item on an Indiana file, and desk adjusters in Marion County and the surrounding metro counties routinely skip it, pricing the claim as a simple repair instead. Verify with local building dept Confirm the applicable threshold and edition with the local building department for that address.
Ice barrier requirements at the eave are a code question, not a preference
The current residential code requires an ice barrier membrane in the eave and valley zone in the climate conditions Indiana experiences every winter, and it is one of the most consistently omitted line items on a carrier estimate written from a summer storm photo rather than a full assembly inspection. Once the deck is exposed at tear off, whether the existing membrane meets the current requirement is a documented fact, not an argument.
The carriers writing Indiana, and the patterns that hold
State Farm, American Family, Farmers, and Allstate carry a large share of the residential book across the state's metro markets. Erie Insurance has a strong footprint in Indiana as well, particularly on policies that carry guaranteed replacement cost as a base feature rather than an endorsement. Auto-Owners and Westfield both carry meaningful share specifically in Indiana's smaller cities and rural counties, markets the larger national carriers price less aggressively for. None of that book behavior is random. Erie's guaranteed-replacement-cost policies tend to open the door to full-slope matching arguments that a standard actual-cash-value policy from a metro carrier will not, and the rural Westfield and Auto-Owners files often move faster on collateral soft metal claims than the catastrophe-team files coming out of Indianapolis, simply because the file count per adjuster is lower outside the metro corridor. Mapping which carrier resists which line item, before the supplement is drafted, is what keeps the document from arguing a point that carrier was always going to concede and missing the one it was always going to fight.
The volume problem shows up hardest after a widespread hail outbreak or a derecho event, when the file count spikes across dozens of counties at once and catastrophe teams get measured on throughput rather than accuracy. A file scoped under that kind of pressure comes back light on ridge system detail, collateral evidence, and any ice-related loss sitting underneath a summer storm claim. The reinspection supplement is what gets a second adjuster back on the roof after a stalled Indianapolis or Fort Wayne file goes quiet, this time working from a document that already carries the ridge measurements, the soft metal photos, and the ice-barrier condition rather than asking the field rep to rediscover all three from scratch. Where an aging roof schedule or a depreciation holdback cut the payout further, depreciation recovery is the separate fight worth having.
What gets recovered on an Indiana roof file
Ordered by how often the item is missing when a file reaches our desk.
Status key: In scope. Usually omitted. Code driven. Verify with the authority having jurisdiction. Every status is spelled out in words beside the item, so nothing depends on color.
Ice and water shield at eaves and valleys
Code driven
Freeze-thaw cycling backs meltwater up under the shingle course at the eave every winter, and the current residential code requires the membrane in that zone. A carrier estimate scoped in July from a storm photo routinely leaves it off entirely.
Ridge vent, hip and ridge cap, and closure strip
Usually omitted
Straight-line wind events lift and crease ridge cap across a wide path, but a fast estimate prices one operation and folds the other two into the shingle line as if they were free labor.
Starter course at eaves and rakes
Usually omitted
Shingle makers void wind coverage when this course is missing or buried inside the field count instead of run as its own separate strip, and a squares-based estimate drops it more than any other single component.
Decking replacement where hail or freeze-thaw moisture compromised the panel
Verify with local building dept
Older Indiana housing stock still carries board sheathing in places, and repeated freeze-thaw cycling plus hail impact opens seams that only show once the old covering comes off. Confirm the condition at tear off before the line is finalized.
Full roof replacement under the existing building provisions
Verify with local building dept
675 IAC 14-4.4 sets a repair threshold, and past that line an Allen County or Marion County building official will require a full-code roof rather than a patch matched to the old one. Confirm the applicable threshold and edition with the local building department for that address.
Drip edge at eaves and rakes
Code driven
Current code requires it, and a large share of the roofs coming up for replacement in Indiana right now were installed before that requirement was in force. A repair-minded estimate leaves it out by default.
Synthetic underlayment upgrade
In scope
Indiana's freeze-thaw winters and hail-heavy summers both argue for a synthetic underlayment over felt, and the material and labor difference is a legitimate line that a bare-minimum estimate skips.
Pipe boot and vent flashing replacement
Usually omitted
The rubber collar on a pipe boot is one of the most hail-vulnerable components on the roof and one of the most consistently excluded, even when the impact is photographed and dated.
Valley flashing replacement
In scope
Valleys concentrate both meltwater in a freeze-thaw winter and hail impact in a summer storm, and a valley that has already taken both kinds of damage in the same season needs the metal replaced, not resealed.
Detach and reset on gutters, downspouts, and satellite mounts
Usually omitted
Nothing gets roofed under a mounted dish or a run of gutter still attached to the fascia. The removal and the reset are real labor lines whether or not the original estimate opened them.
Collateral hail damage on soft metals and exterior components
Usually omitted
Gutter aprons, roof vents, window screens, and AC condenser fins register hail impact clearly when a weathered shingle field reads ambiguous, and that evidence is what turns a denied or repair-only file into an approved replacement.
Overhead and profit on multi trade files
In scope
A single Indianapolis derecho file that hits roof, gutter, siding, and interior water damage together needs a general contractor to sequence those trades, and that coordination need, not the dollar total, is what qualifies the claim for O and P.
Each becomes a written line with a reason attached, inside a real Xactimate file. Depending on the claim it ships as a roofing supplement, an Xactimate supplement package, a supplemental estimate, or a full claim estimate written from scratch.
What happens to your file after you send it
- 01
The carrier estimate gets read line by line against the roof
Not skimmed. We pull the estimate apart against your measurements and photos, marking every line where the assembly written does not match what that roof needs in that jurisdiction.
- 02
Code and manufacturer requirements get sourced before they get argued
Indiana runs one statewide residential code, but enforcement and any local amendment still sit with the authority having jurisdiction for that address, so the AHJ gets confirmed before anything is cited in writing.
- 03
The supplement is written in Xactimate and delivered as a PDF
Real file, real price list, real sketch. You get the PDF as the deliverable, and the ESX free any time you ask for it. Retail estimate work with no supplement attached delivers the ESX. Written same day or next day, submitted next day. One to three extra days on large commercial and multi structure work.
- 04
We stay on the file until the carrier answers
Follow up, desk adjuster calls, and reinspection support when the carrier sends someone back out. Response runs about three weeks as a general expectation, and the file does not close on our side because it went quiet on theirs.
Two promises, stated separately
Promise one: the fee
The standard fee is 15 percent of supplemental recovery. If a file produces no additional approved recovery, you pay nothing on that claim. That is the whole fee structure, and it applies claim by claim.
Promise two: the guarantee
Send us an average of 2 claims per week for 12 months. If that volume does not produce a minimum of six figures in additional margin for your company, we write you a $5,000 check at the end of the 12 months. The volume, the 12 month term, the six figure threshold, and the $5,000 figure are one set of terms and they always travel together.
Two different promises, no overlap. The fee describes what a single claim costs you. The guarantee describes what a year of steady volume is worth. Nothing in the fee structure is a guarantee, and the guarantee does not change the fee.
Indiana questions we get from contractors
Why does an Indiana hail estimate come back thin so often?
Because hail in Indiana is a statewide event rather than a coastal or single-corridor problem, and a single storm cell can generate hundreds of claims across several counties in one afternoon. Catastrophe teams working that volume default to a squares count with a shingle line and little else. What gets skipped is the ridge system, the soft metal evidence, and the collateral damage on gutters, screens, and vents that documents the hit when the shingle field alone reads ambiguous.
Does Fort Wayne use a different roofing code than Evansville?
No, and that surprises contractors used to a locally-adopted Midwest state. 675 IAC 14-4.4 puts the Fire Prevention and Building Safety Commission in charge of adopting the residential code for the entire state, so the citation itself reads the same in Allen County as it does in Vanderburgh County. Permitting, inspection, and any local amendment still sit with the building department covering that address, so the AHJ still gets confirmed before a citation ships, but the underlying rule does not change at the county line.
What does a derecho do to an Indiana roof file that a normal wind claim does not?
A derecho pushes a long line of damaging straight-line wind across many counties in a single pass, and the damage signature is different from a tornado track. Instead of a narrow band of catastrophic loss, you get a wide swath of creased shingles, lifted tabs with broken seal strips, and displaced ridge cap spread across an entire region at once. Carriers process that as ordinary wind and price it thin, when the actual assembly damage runs the width of the storm's path, not just the roofs directly in a tornado's line.
What does freeze-thaw cycling actually damage on an Indiana roof that a summer inspection misses?
Indiana runs enough freeze-thaw cycles each winter that water trapped under a shingle field or in a compromised valley expands and contracts repeatedly rather than just freezing once. That cycling works fasteners loose, splits sealant at flashing laps, and drives ice back up under the shingle course above the eave when a warm afternoon melts snow that refreezes overnight. None of that shows up as hail bruising, so an estimate written for storm damage alone leaves the ice-related deck and underlayment loss on the table.
Do you work Auto-Owners and Westfield files, and why do those two carriers come up so often in Indiana?
Yes. Both carriers carry significant book share in Indiana's smaller cities and rural counties specifically, in addition to the national names writing the metro markets, and each has settled internal habits about which line items get paid without a fight and which get kicked back for justification. Knowing which is which before the estimate goes out is what keeps a supplement from bouncing on something the carrier was never going to contest in the first place.
How fast is turnaround, and what does it cost?
Estimates are written same day or next day and submitted next day. Larger commercial and multi structure files take one to three extra days, said up front. Carrier response runs about three weeks as a general expectation. The standard fee is 15 percent of supplemental recovery, and a file with no additional approved recovery owes nothing on that claim.
