Michigan averages more than a dozen significant hail events per year. When one hits your neighborhood, your insurer sends an adjuster, the adjuster writes an estimate, and that number becomes the carrier's opening position -- not necessarily what your roof replacement actually costs.

After 33 years working hail claims across SE Michigan, we can tell you the gap between initial adjuster estimates and actual replacement cost is almost never zero. This guide explains what your policy should cover, what adjusters routinely miss, and how to make sure you recover the full amount.

How to Know If Your Roof Has Hail Damage

Hail damage is not always visible from the ground. What to look for:

Do not rely on a ground-level inspection to determine whether you have a claim. Have a licensed contractor get on the roof. Functional damage that affects the waterproofing life of your roof is a covered loss -- it does not need to be actively leaking today.

What Does Homeowners Insurance Cover for Hail Damage in Michigan?

Michigan standard homeowners policies (HO-3 and HO-5) cover hail as a named peril under Coverage A (Dwelling) and Coverage B (Other Structures). This means:

ACV vs. RCV: The Number That Changes Everything

Your declarations page will show either RCV (Replacement Cost Value) or ACV (Actual Cash Value) coverage for your roof. This distinction is significant:

Important: even on ACV policies, you are entitled to the Xactimate line-item scope you would receive on an RCV policy. The depreciation percentage reduces the payment -- it does not reduce what gets measured and written into the estimate. Adjusters on ACV claims sometimes write reduced scope as well as reduced payment. Do not let them conflate the two.

What Adjusters Miss on Michigan Hail Claims

The list of items routinely absent from initial adjuster estimates on hail claims:

Full Roof Replacement vs. Spot Repairs

Michigan follows the matching doctrine. If hail-damaged shingles cannot be reasonably matched to undamaged shingles in color, texture, and overall appearance -- because the product is discontinued, the color run changed, or weathering has shifted the appearance of existing shingles -- you are entitled to full replacement. Adjusters frequently write partial repairs. This is the single most common supplement item on hail claims.

All Roof Planes

Adjusters sometimes write only the planes with the most visible damage. In SE Michigan, hail events hit all roof exposures -- the leeward side may show less bruising but still have granule displacement that compromises waterproofing. All damaged planes belong in the scope.

Gutter Systems

Complete gutter systems -- troughs, downspouts, gutter guards, and hangers -- are regularly omitted or underscoped. Dented gutters are functionally impaired, not just cosmetically affected. The entire gutter run on the damaged elevation belongs in the scope.

Drip Edge and Flashing

Drip edge and step flashing are code requirements on a new roof install in Michigan. When an estimate writes a full roof replacement but omits drip edge and step flashing, the code-required scope is not being written. These line items are typically small but are legitimate components of a compliant scope.

Overhead and Profit

When a general contractor (GC) is required to coordinate the roofing scope alongside other trades, you are entitled to 10% overhead and 10% profit on top of direct costs. Michigan carriers routinely suppress O&P on roofing-only scopes by claiming no GC coordination is required. When additional trades are involved -- siding, gutters, interior work, HVAC -- O&P is mandatory. Even on roofing-only scopes, a licensed GC managing the process is entitled to O&P.

Interior Damage from Delayed Discovery

Hail damage often creates latent leaks. A roof may hold through one season after a hail event and fail the next spring. When water intrusion eventually occurs, it is attributed to the hail loss date -- but the interior scope needs to be built separately and supplemented to the original claim. Do not let the carrier attribute interior damage to a lack of maintenance when the root cause was an uninspected hail loss.

The Supplement Process: Closing the Gap

A supplement is a line-by-line request to increase the carrier's approved scope. It uses the same Xactimate pricing database the carrier used for the original estimate. Every item has a justification: photos, measurements, code references, or manufacturer specs.

Typical hail claim supplement components on SE Michigan residential losses:

  1. Full replacement scope where adjuster wrote partial repair
  2. Gutter and downspout system (full run)
  3. Additional roof planes with documented granule loss
  4. Drip edge and flashing (code compliance line items)
  5. Overhead and profit at 10/10
  6. Recoverable depreciation release letter (after completion)

On a typical Wayne or Oakland County hail claim, supplement recoveries run from $3,000 to $25,000 above the initial adjuster estimate. The number varies based on roof size, age, materials, and how aggressively the first estimate was written.

Timing Your Hail Damage Claim in Michigan

File promptly once you discover damage. Michigan policies require notice as soon as reasonably possible after a covered loss. Most have a one-year or two-year suit limitation period, but the notice requirement is separate -- waiting too long to file can give the carrier a denial basis unrelated to the merits of the loss.

If you noticed damage this year from a storm last year, document the discovery date clearly and file. A restoration contractor can provide a written assessment confirming when the damage was discovered, which supports the late-discovery narrative.

What to Do If Your Hail Claim Was Denied or Underpaid

A denial or low estimate is not the final word. Options:

Phase III Construction has worked all four of these paths on Michigan hail claims. The supplement route resolves the majority of underpayment situations without escalating to appraisal or regulatory involvement.

If you are in Wayne, Oakland, Washtenaw, Livingston, or Macomb County and believe your hail claim was written short, contact us. We review the estimate, identify the gaps, and tell you exactly what additional recovery looks like before you commit to anything.
