Chicago, IL
The roof does not end at the edge here. It turns and goes up a wall, and that is where the estimate loses the money
On a pitched roof with an eave, the covering runs to the end of the deck and stops, and everything at that stop belongs to one trade. Put a parapet there and the same building asks a harder question: the membrane turns up the inside face, terminates part way, and masonry continues above it. A carrier estimate is organized by trade, so that vertical strip falls between the roofing lines and the wall lines and gets funded by neither. The peril is rarely the argument on these files. The boundary is.
By Kyle Hamrick, Founder
A scope boundary is not a soft disagreement. It is a specific claim about which surface a given operation is performed on, and it can be settled with a drawing, a measurement, and a provision quoted from the document the permit office is holding. Files that turn on a boundary get built that way here, in that order, before anybody starts arguing about quantities.
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 Chicago file is code mechanism, carrier behavior, and claim pattern, confirmed for the address rather than assumed from a statewide rule. More about Kyle.
What a parapet actually does to a claim, mechanically
It relocates the termination from a horizontal plane to a vertical one
An eave termination is easy to price because nothing about it requires a decision. The deck ends, the covering ends a few inches past it, metal catches the drip, and every operation involved sits flat and gets counted in the same unit as the field above it. A parapet takes that same termination and stands it on end. The membrane turns ninety degrees at the deck-to-wall junction, climbs, and stops at a height somebody chose. Above the stop is masonry. Below it is roof.
Everything expensive about the detail lives in the climb. It is roofing material and roofing labor performed on a vertical surface, at a slower rate, against a substrate that is not the deck. It needs the transition at the bottom, the run itself, a mechanical termination at the top, and a second piece of metal shedding over the top of the first. None of that is measurable in squares of field, which is the unit a first estimate is built in, so the entire vertical strip is invisible to a quantity takeoff that never left the horizontal plane.
It puts the work in the seam between two trades in the estimate
A carrier estimate is not organized by building. It is organized by trade, and each trade has a section with its own line items and its own reviewer expectations. A parapet detail does not sit cleanly inside either of the two sections it touches. Ask a reviewer working the roofing section and the answer is that the wall is not roofing. Ask the same reviewer about the wall and the answer is that the masonry was not damaged, which is frequently true and completely beside the point. Nobody declines the scope. It simply has no home, and an item with no home does not get written.
This is why the argument has to be made as a boundary argument rather than as a damage argument. The question is not whether the wall was hurt. It is which trade performs the operation of getting water off a roof and past a vertical obstruction, and the answer is the roofing trade, on the roofing side of a wall, using roofing materials. Once the file states the boundary in those terms and puts a drawing behind it, the reviewer is no longer choosing between two sections. There is one place the work belongs and the file has already said which. The roof claim inspection checklist sequences the edge documentation so it is on record before the detail comes apart, since tear off erases the proof of what was actually up there.
It turns an ordinary reuse assumption into a condition finding
Most first estimates on this edge condition assume the metal already up there comes back down and goes back up. That assumption is doing real work in the number and it is almost never stated out loud. On a parapet the metal in question has been sitting in a joint in a masonry wall, taking water off the top of the assembly, for however long the last roof lasted. Whether it can be reinstalled is a question about its actual condition, and the city's own adopted text answers it rather than leaving it to preference.
That changes what the contractor has to bring. Not an opinion that the counter flashing is tired, but a photograph of corrosion at the reglet, a note on where the metal is deformed, and the provision that says deteriorated metal is not reinstalled. One of those is a conversation. The other one ends it.
The citation path on a Chicago roof, and why a model section number misses it
The reroofing section of the building code is the one Chicago did not adopt
Section 14B-15-1511 of the Chicago Building Code states that the model code's reroofing section is not adopted, and substitutes language sending roof repairs and roof replacement to Section 306 of the Chicago Building Rehabilitation Code. That is a small sentence with a large consequence: the reroofing rules on a file inside this city are not in the building title at all, they are in the rehabilitation title, and an estimator citing a model section number by habit is quoting text this city expressly declined. The Department of Buildings administers both titles and the city council adopts and amends them. Verify with local building dept Confirm the current adopted text and any interpretation in force with the department before a citation goes in writing.
The parapet is named in the adopted text, and it decides an obligation
Exception 2 to Section 306.1 requires roof replacement or roof recover of an existing low-sloped roof to comply with the roof insulation requirements for new construction, unless adding insulation above the structural roof deck is infeasible due to the height of existing parapets, equipment curbs, skylight curbs, window sills, door thresholds, and similar elements with flashing into the roof system, and it closes by stating that in no case shall the work reduce the insulating value of the roof. That is a dimension deciding a requirement. It is the reason the edge condition on this kind of building is a measurement task on the first visit rather than something to sort out later, and it cuts in both directions rather than favoring either side of the file.
Where a roof edge stops being optional entirely
Sections 306.7 and 306.8 state that when roof replacement is performed, the edges of a low-sloped roof adjoining a shaft or a court enclosed on all sides, and skylights and other openings in the plane of a low-sloped roof, are made to comply with Section 1516. Section 1516.2 in turn requires those edges to be provided with a parapet, extended masonry, or guard, or a combination of them, meeting the guard requirements. On a building with a light court or an enclosed shaft, that is an obligation triggered by the replacement itself rather than by the damage, and it is the kind of line a first estimate never contains because nothing about the storm caused it. Verify with local building dept Confirm whether the specific edge on the parcel is one the provision reaches before pricing it.
The carriers writing Chicago, and the shape of the disagreement
State Farm, Allstate, Travelers, Liberty Mutual, Erie, American Family, Country Financial, Farmers, and Nationwide all carry meaningful volume across this market, alongside commercial and specialty writers on the larger buildings. Naming the company on the policy is not what wins a file here, and this page will not pretend otherwise by attaching a personality to each one. What matters is that the reviewer on the other end is reading a document organized by trade, and the item in dispute is one that does not sit neatly in a trade.
The recurring move is therefore not a denial. It is a silence. The membrane gets priced, the field quantity looks defensible, and the vertical work at the edge is simply absent, with nothing in the document acknowledging that a decision was made. A supplement that responds by asserting the item was missed invites a slow argument about whether it was owed. A supplement that responds with the edge drawn, the operation named as roofing performed on a vertical surface, and the adopted provision quoted for the reuse and reconstruction requirements is arguing about a boundary the reviewer can actually check. That is a faster conversation and a shorter one.
Read the policy before any of it goes out. Forms written in this market carry wind and hail deductibles written as a percentage of the building limit, cosmetic carve-outs that exclude dented metal from the loss, and payment schedules that settle an older covering at a discount. Any of the three can take back at settlement what the scope argument just earned. Where the check was already cut on that footing, depreciation recovery is argued separately on its own paperwork. Where a carrier has to put somebody back on the roof to settle an edge condition that cannot be resolved from a photograph, the reinspection supplement exists so the drawing and the condition evidence are already in hand before that visit gets scheduled.
What gets recovered on a Chicago 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.
The roof edge drawn as a termination detail before any quantity is written
Verify with local building dept
Every argument on this kind of file depends on where the estimator thinks the roof ends, and on a parapet that answer is a decision rather than an observation. Fix it first, in a drawing, with the turn-up height and the termination point marked. An estimate that never says where the roofing stops cannot be checked against one that says something different, which is how two numbers about the same building end up arguing past each other for a month.
Base flashing up the inside face of the parapet, priced as roofing on a vertical surface
In scope
The membrane does not stop at the deck. It turns and climbs the inner face of the wall to a height the assembly requires, and that vertical run is roofing labor performed off the horizontal plane, at a different production rate, with its own material. A first estimate built around a field quantity in squares has no row that captures a vertical foot of anything, so the run disappears without anyone deciding to leave it out.
Termination bar, sealant, and the fastening pattern at the top of the base flashing
Usually omitted
The top edge of that vertical run has to be mechanically held and sealed or the whole climb is decorative. It is a linear-foot item with fasteners into masonry, a bead of compatible sealant, and a crew working from the roof side against a wall. Nothing about it reads as roofing to somebody scanning a photo for missing shingles, and nothing about it reads as masonry to somebody pricing the wall.
Counterflashing cut into the wall, distinguished from the base flashing underneath it
In scope
Two different pieces of metal are doing two different jobs here, and a scope that names only one of them has funded roughly half the detail. The base flashing carries water off the membrane and up the wall; the counterflashing sheds water over the top of it and is let into the masonry. Reusing existing counterflashing is also a decision the adopted code speaks to directly, which makes it a citable line rather than a preference.
Metal counterflashing and edging refused for reuse where rusted, damaged, or deteriorated
Code driven
Section 306.5 of the Chicago Building Rehabilitation Code states that existing vent flashing, metal edgings, drain outlets, collars and metal counterflashings shall not be reinstalled where rusted, damaged or deteriorated, and that aggregate surfacing shall not be reinstalled at all. That converts a judgment call about salvage into a documented condition finding. Photograph the corrosion, and the reuse the estimate quietly assumed is closed by the city's own adopted text.
Metal primed before bituminous material is adhered to it
Code driven
Section 306.6 holds the rebuilt flashing to whatever the manufacturer's own instructions specify, and adds a separate requirement: metal is primed before bituminous material goes onto it. Priming is its own pass with its own can and its own crew minutes, it happens only where a membrane meets a vertical metal surface, and a price list built around pitched residential work has no row waiting for it.
Coping cap, its fastening, and the joint treatment across the top of the wall
Usually omitted
The cap sitting across the top of the parapet is the part most likely to be argued as somebody else's trade, because it looks like a piece of the wall from the sidewalk and it looks like trim from the air. It is neither. It is the horizontal surface that keeps water out of the top of a masonry assembly, it is fastened and jointed as its own operation, and it gets disturbed the moment the flashing under it is replaced.
Parapet height measured against the insulation requirement rather than assumed away
Code driven
Exception 2 to Section 306.1 relieves the new-construction insulation requirement only where added thickness above the structural deck is infeasible because of the height of existing parapets, curbs, sills, thresholds, and similar elements with flashing into the roof system, and states that in no case may the work reduce the insulating value. A tape measure settles which side of that you are on. Left unmeasured, the exception gets claimed by whichever party benefits from claiming it.
Repair scope tested against the 25 percent surface-area line in Section 306.1
Code driven
Roof repair not exceeding 25 percent of the surface area of an existing roof may comply with Chapter 4 of the rehabilitation code, and past that the work answers to the recover and replacement requirements instead. Establishing which side of the line the actual damage falls on is a measurement, not a negotiation, and it decides how much of the chapter comes with the job.
Layer count and deck condition documented before a recover is priced
Code driven
Section 306.3.1 allows a recover only in listed circumstances, then shuts it off on three separate findings: saturation or decay leaving the old covering unfit as a base underneath, a covering made of tile in any of its listed forms, and a building already carrying two or more applications, that last one unless a condition report proves the structure can hold the added weight. That report is a defined instrument under Section 14X-1-104, sealed by a registered design professional and filed with the building official for a fee, so it is a cost and a calendar item rather than a memo. A probe and a cut settle the rest, and the cheapest path on the page closes itself.
Wall face above the flashing inspected for water entry, separately from the roof plane
In scope
Section 14X-3-303.6 requires exterior walls to be free of holes, breaks, loose or rotting materials, and conditions that might admit rain or dampness to the interior, and 14X-3-303.8 covers cornices, corbels, trim, and similar features. Water coming in high on a wall above a failed termination is an interior loss the roof photograph never shows, and the inspection that finds it is a separate walk from the one on the deck.
Overhead and profit on multi trade files
In scope
The moment a claim reaches the membrane, the metal on the wall, tuckpointing behind a reset counterflashing, and a ceiling under the breach, three or four trades need sequencing against one another on one address with one staging area. What earns the line is how many trades are queued behind one another, never how large the claim eventually totals.
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 roof edge gets defined before the carrier number gets argued with
We mark where the roofing terminates on your drawing, note the turn-up and the cap condition, and set that against what the carrier's document assumed. Most of the disagreement on these files turns out to be a boundary disagreement wearing a quantity dispute's clothing.
- 02
The citation is traced to Chicago's own adopted text, never to a model section number
Section 14B-15-1511 does not adopt the model reroofing section; it sends the work to Section 306 of the Chicago Building Rehabilitation Code. Every code-driven line we write points at the provision the Department of Buildings is actually holding, with the parapet, insulation, flashing, and reuse language quoted as adopted here.
- 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. 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
We keep working the desk adjuster and stand ready for the second visit whenever a carrier decides to send somebody back up. About three weeks is the working expectation for an answer, and this file stays open on our side until one arrives.
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.
Chicago questions we get from contractors
Why does a parapet change what a carrier estimate is willing to pay for?
Because a parapet moves the end of the roof off the horizontal plane and turns it into a vertical surface, and a carrier estimate is organized by trade rather than by building. On an eave the roof simply stops, and everything at that stop reads as roofing. On a parapet the membrane turns up the inside face, runs to a termination, and the wall keeps going above it. A reviewer pricing from a roof photo sees a wall and prices a wall trade, or prices nothing at all, because the wall was not damaged in the way a wall gets damaged. The base flashing, the termination, the counterflashing tucked into the masonry, and the cap on top are all roofing work performed on a vertical surface, and they fall in the gap between the two trades in the estimate. The scope boundary is where the money goes missing, not the peril.
Which code actually governs a Chicago re-roof, and does the state rulebook apply?
The Chicago Construction Codes govern, adopted and amended by the city council and administered by the Department of Buildings. On reroofing the path is specific and worth tracing, because it is not where most estimators would look. Section 14B-15-1511 of the Chicago Building Code states that Section 1511 of the model building code is not adopted, and replaces it with language sending roof repairs and roof replacement to Section 306 of the Chicago Building Rehabilitation Code, Title 14R. So the operative reroofing text on a Chicago file lives in the rehabilitation title, not the building title, and a citation aimed at a model code section number is aimed at a provision this city expressly did not adopt.
What is the 25 percent threshold in the Chicago Building Rehabilitation Code and why does it matter on a claim?
Section 306.1 states that materials and methods used for roof recover and roof replacement shall comply with Chapter 15 of the Chicago Building Code, and that roof repair not exceeding 25 percent of the surface area of an existing roof may comply with Chapter 4 of the rehabilitation code instead. That single sentence is the fork in the road on a low-slope claim. Below the line the work answers to the repair chapter. At or past the line it becomes recover or replacement and picks up the full chapter, including the insulation question, the flashing reconstruction requirement, and the bar on reinstalling deteriorated metal. A carrier scope written as a patch is not just a smaller number. It is an attempt to keep the file on the near side of a threshold the city's own code draws.
The carrier says the roof insulation stays as-is. Does the parapet height have anything to do with that?
It does, and this is the one place in the adopted text where a parapet is named outright. Exception 2 to Section 306.1 requires roof replacement or roof recover of an existing low-sloped roof to comply with the roof insulation requirements for new construction, unless installing additional insulation above the structural roof deck is infeasible due to the height of existing parapets, equipment curbs, skylight curbs, window sills, door thresholds, and similar elements with flashing into the roof system. The same exception then states that in no case shall the work reduce the insulating value of the roof. So the parapet is a measurable dimension that decides an obligation, which means it is a documentation task with a tape measure attached rather than a matter of opinion, and the answer runs both directions: it can relieve a requirement, and it can fail to relieve one.
Does Cook County's building department govern a roof inside the city limits?
No. Cook County's own Department of Building and Zoning states that it oversees building and zoning matters in the unincorporated areas of Cook County and the Forest Preserves, and directs inquiries about properties in incorporated jurisdictions to the applicable local authority. A Chicago address is incorporated, and an incorporated jurisdiction here writes and administers the construction rules for itself, so a county reference attached to a city parcel points at a body that never issued that permit. The county is a real authority with a real service area. That service area simply does not include the city, and knowing where it stops is worth more on a file than assuming a county is a catch-all.
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.
Chicago and the wider Illinois market
Chicago sits inside the wider Illinois market and is the one address in it that answers to a construction code the city wrote for itself. Aurora, Rockford, Peoria, Springfield, and Champaign each answer to their own adopting authority and each carry a different citation on the same kind of roof. Files also come in from the incorporated suburbs and from unincorporated parcels around the city, and the first thing settled on any of them is which office issues the permit.
Send one Chicago file and see where its roof was assumed to end
Send the carrier document, your measurements, photographs of the edge condition and the metal in the wall joint, and the declarations page. What comes back names the termination, prices the vertical work as the roofing operation it is, and quotes the provision the Department of Buildings actually holds rather than the model section somebody assumed.
