Labor Depreciation on Michigan Roof Claims, Explained

When the first check arrives on a storm damaged roof, the number rarely matches what a new roof actually costs. Part of the gap is your deductible. The rest is usually depreciation, the discount for the years your old roof already served. And buried inside that depreciation line sits one of the most contested questions in property insurance: did the carrier depreciate only the shingles, which genuinely wear out, or also the labor to tear off and install them, which is consumed once on installation day and does not age on your roof at all? On an asphalt replacement that runs $9,000 to $18,000 in Macomb County, with most homes landing at $12,000 to $16,000, the answer can swing an actual cash value settlement by thousands of dollars. This guide explains what labor depreciation is, why it is controversial, and how legislatures and courts around the country have wrestled with it. Michigan's own treatment is a legal question that has shifted over time, so we present it strictly through the verified sources listed at the end of this page rather than paraphrase from memory, and nothing here is legal or insurance advice.

01 / THE CONCEPTWhat labor depreciation actually means

Start with the settlement math. An actual cash value settlement pays the replacement cost of the damaged property minus depreciation for age and wear. Our roof depreciation guide covers the mechanics in full, but the short version is that a fifteen-year-old roof has already delivered most of its service life, so an ACV settlement pays you for the used roof you lost, not the new roof you need. Nobody seriously disputes that the materials can be depreciated. Shingles bake, granules wash into the gutters, seal strips fatigue. A used shingle is worth less than a new one in any honest accounting.

But a roof invoice is not just shingles. It is tear-off, disposal, underlayment, flashing work, and above all skilled labor, and on many jobs the labor and labor-heavy line items make up a large share of the total. Here is the controversy: labor is performed once, on installation day, and then it is done. The crew's work does not sit on your roof slowly wearing out the way a shingle does. When a carrier applies its depreciation percentage to the entire replacement cost, labor included, homeowners and a number of courts have asked a pointed question: what exactly depreciated? The practice is called labor depreciation, and whether it is lawful depends on the policy language and on the law of the state where the house sits.

02 / THE MATHThe stakes on a typical Macomb County claim

The numbers make the fight concrete. Take a Macomb County home whose full asphalt replacement would cost $16,000, the upper edge of the typical range, and suppose the invoice splits into $8,000 of materials and $8,000 of labor and labor-driven work. That split is an illustration, not a quote; the real breakdown on your roof comes from a written estimate, and you can rough in your own starting figure with the 60-second cost calculator. Now say the roof is fifteen years into a twenty-year expected life, and the adjuster depreciates straight line, which works out to 75%.

If depreciation applies to materials only, the carrier withholds 75% of the $8,000 in materials, which is $6,000, and the ACV settlement is $10,000 before the deductible. If depreciation applies to the entire invoice, the carrier withholds $12,000 and the settlement drops to $4,000. Same roof, same storm, same policy premium, and a $6,000 swing that turns on nothing but which lines the depreciation percentage touched.

Notice what the illustration leaves out, because real settlements stack these effects. The deductible comes off after depreciation, so a homeowner with a percentage deductible on a depreciated-labor settlement can watch a five-figure replacement cost shrink to a check that funds little more than a repair. And the depreciation percentage itself is a judgment call: the adjuster chooses the expected life and the condition adjustment, and those choices compound with the labor question. Two adjusters can look at the same roof and produce ACV figures thousands of dollars apart without either doing anything improper, which is exactly why the worksheet behind the check deserves as much attention as the check itself.

One important scoping note. If you carry replacement cost coverage and you complete the work, the withheld depreciation is often recoverable once the invoice is submitted, which softens the sting; the two settlement types are compared line by line in our ACV versus RCV guide for Michigan. Labor depreciation bites hardest where the ACV number is the final number: policies with ACV-only roof endorsements, claims where the homeowner cannot fund the rebuild and never recovers the holdback, and any settlement where depreciation is flagged non-recoverable.

03 / THE DISPUTEThe argument on each side

The carrier side of the argument runs like this. Actual cash value is meant to reflect the fair value of the property you lost, and what you lost was a used roof, a finished product in which materials and labor are inseparable. You cannot buy fifteen-year-old shingles installed with brand new labor; the market does not sell roofs in halves. On that view, depreciating the whole replacement cost, labor included, is simply the honest way to price a used asset, and skipping the labor share would hand the homeowner more than indemnity requires.

The homeowner side answers that depreciation exists to account for wear and consumption, and labor experiences neither. The tear-off crew's work in 2011 is not more worn out in 2026 than it was the day it was finished; it was never a thing on the roof at all. Depreciating it does not price a used asset, it simply shrinks the check, and it leaves the policyholder structurally short of what it costs to be made whole. Courts sympathetic to this view have also leaned on a rule of insurance interpretation: when a policy uses a term like actual cash value or depreciation without defining it, ambiguity is generally read against the company that drafted the form.

Materials wear out on your roof. Labor was finished the day the crew drove away. Whether a carrier may depreciate the second the way it depreciates the first is exactly what statehouses and courts have been fighting about.

04 / THE MAPHow other states have answered the question

This is not an abstract debate. Over the past decade the question has been answered, in different directions, across much of the country. Some state legislatures have passed statutes that restrict or forbid depreciating labor in ACV settlements. Some insurance departments have addressed the practice through regulations or bulletins that bind the carriers they license. And a substantial body of litigation, including class actions, has produced appellate decisions on both sides: some courts holding that undefined policy language does not permit labor depreciation, others holding that it does, with results often turning on the exact wording of the loss settlement provision.

Carriers have responded to the losses by redrafting. Many current policy forms now define actual cash value expressly, some stating outright that depreciation may be applied to all components of the cost, labor and overhead included. That drafting matters enormously: a homeowner in a state without a protective statute, holding a policy that expressly authorizes labor depreciation, is in a very different position from a neighbor whose older form never defined the term. A state-by-state survey belongs to the sources at the end of this guide rather than to prose that will drift out of date, but the pattern is the point: this is a live, moving area of law, decided state by state and form by form.

Two practical lessons travel across state lines regardless of where any one legislature landed. First, the fight is usually about undefined terms: where policies left actual cash value or depreciation undefined, homeowners had arguments; where forms now spell the method out, the language itself tends to control. That means the single most useful document in this entire debate is your own policy, read closely, before a storm rather than after. Second, the dollars involved were large enough to fund years of class litigation and to prompt statutes, which should tell a skeptical reader something: this is not contractor folklore about stingy adjusters, it is a settlement methodology dispute that legislatures and appellate courts considered worth deciding.

05 / MICHIGANWhere Michigan stands right now

Here is where an honest guide slows down. Michigan's treatment of labor depreciation is a question of Michigan statute, Department of Insurance and Financial Services guidance, and Michigan case law, and it is precisely the kind of question where a confident paraphrase can be wrong by the time you read it. So we do not paraphrase. The controlling authorities we rely on are listed in the sources at the end of this page, and we update that list as the landscape changes. What we can tell you without qualification is how the question gets decided on any individual claim: first the policy form, because if your loss settlement provision defines actual cash value and speaks to labor, that language governs unless Michigan law overrides it; then whatever Michigan statute, DIFS position, or controlling decision applies to that language.

We can also tell you the question is far from academic here. The August 2023 storms that placed Macomb County inside federal disaster declaration DR-4757 pushed a wave of roof claims through local carriers, and settlement methodology, including how depreciation was calculated and what it was applied to, is a recurring theme in the underpayment disputes that followed. If your claim from that event or any storm since settled at ACV, the depreciation worksheet behind your check is worth a careful read, and our storm damage and insurance claims page explains how we document roofs for exactly these conversations.

06 / YOUR CLAIMHow to check your own settlement for labor depreciation

You do not need to resolve a legal debate to find out what happened on your own claim. You need the paperwork, and the discipline to read it line by line.

1. Get the full adjuster estimate, not the summary. Carrier estimates are built line by line, and the detailed version shows replacement cost, depreciation, and ACV for every item. You are entitled to it; ask for it in writing if it did not come with the check.
2. Find the labor-heavy lines. Tear-off and disposal are almost entirely labor. If those lines carry the same depreciation percentage as the shingle line, labor was depreciated on your claim.
3. Ask the carrier to cite its authority. A written request works: which policy provision defines actual cash value, and what authorizes applying depreciation to labor? The answer, or the absence of one, tells you a lot.
4. Check the recoverable column. If depreciation is recoverable and you complete the work, the labor question may cost you timing rather than money. If any of it is non-recoverable, the question is worth pressing.
5. Price the real roof. A settlement only looks low or fair next to a real local number. Our published price ranges and a free storm inspection and written estimate give you the Macomb County figure to hold up against the carrier's worksheet, and the replacement cost guide explains every line on ours.

Keep everything in writing as you go. Claim file notes, emails with the adjuster, the estimate versions as they change, and dated photos of the roof before any work begins all become leverage later, and they cost nothing to collect now. Deadlines matter too: policies impose proof-of-loss and suit-limitation windows, and recoverable depreciation typically has a completion deadline attached, so a homeowner who parks a low ACV check in a drawer can quietly forfeit money that was still on the table. If the roof is open to the weather while the paperwork grinds on, emergency tarping is a covered mitigation step under most policies, and we handle tarping calls 24/7 so the dispute does not race the rain.

If the numbers do not reconcile, you have options short of a lawsuit: a documented supplement request, an appraisal demand if your policy includes the clause, a DIFS complaint, or counsel for a claim that warrants it. Our underpaid claim guide walks the escalation ladder step by step. We cannot promise any outcome, and no honest contractor can, but we can put a photo-documented inspection and a line-item estimate in your hands, and we can meet your adjuster on the roof so the conversation happens over the same evidence.
