We know Allstate's claim process inside and out. Phase III Construction helps Michigan homeowners document damage accurately, submit complete estimates, and navigate every step from first inspection to final payment.
Michigan's Allstate Claim Specialists
After 33 years and more than 1,000 insurance claims in Michigan, we have worked alongside Allstate adjusters — both staff and independent — on hundreds of roofing and storm damage projects.
That experience means we understand how Allstate structures its estimates, what documentation their desk adjusters require for supplements, and how the ClaimXperience portal fits into your timeline. We do not guess at these things. We have built our workflow around them.
Our role is straightforward: we inspect your property thoroughly, produce an Xactimate-formatted estimate that reflects actual damage, and work through the claim process with you from initial filing to final payment.
Request a Free InspectionWe produce Xactimate-formatted estimates that match the methodology Allstate's adjusters use, keeping documentation consistent and reducing unnecessary back-and-forth.
When additional damage is discovered during tear-off, we document it with photos and line-item detail and submit directly to Allstate's desk adjuster team.
We help you understand the two-payment structure Allstate typically uses and make sure you recover both the initial ACV payment and the recoverable depreciation.
How It Works
Here is what to expect when you file a storm damage claim with Allstate in Michigan.
File through the Allstate mobile app, at allstate.com, or by calling Allstate's claims line at 1-800-255-7828. Report the date of the storm and describe the areas affected. Allstate will assign a claim number and begin the intake process.
In Michigan, Allstate frequently uses independent (IA) adjusters rather than staff adjusters, particularly following widespread storm events. An independent adjuster is a licensed third-party professional, not an Allstate employee. Their documentation practices can vary by firm and individual, which is why having your own contractor's estimate on hand matters.
The assigned adjuster will schedule an inspection of your property. We recommend having a Phase III representative present. Our team can point out damage that may be overlooked and ensure the adjuster's scope reflects the full extent of what the storm caused.
Allstate's ClaimXperience portal lets you monitor your claim status in real time, upload photos and supporting documents, message your adjuster, and track payment status. After filing, Allstate will provide your portal access credentials.
Allstate typically issues an initial payment based on Actual Cash Value (the replacement cost minus depreciation). Once repairs are completed by a licensed contractor, you submit proof of completion to claim the recoverable depreciation and receive the remaining Replacement Cost Value payment.
Estimating Software
Allstate uses Xactimate, the industry-standard estimating platform, to produce its storm damage scope of loss.
Xactimate generates line-by-line cost estimates based on current regional pricing for materials and labor. Adjusters enter the damage they observe and the software calculates cost. The resulting estimate becomes the basis for your claim payment.
Phase III Construction produces Xactimate-formatted estimates using the same platform and pricing database. When our estimate and Allstate's estimate are built the same way, the review process is more direct. Discrepancies are easier to identify and resolve because both documents speak the same language.
If Allstate's estimate misses items or uses pricing that does not reflect current Michigan market rates, we can identify those gaps precisely, line by line, and address them through the supplement process.
When your contractor's estimate is formatted the same way the insurer's estimate is formatted, there is no translation layer. Allstate's desk adjuster can compare line items directly. Missing items are clear. Pricing differences are documented. The review process is faster and more predictable.
Xactimate pricing is region-specific and updated regularly. We ensure estimates reflect current Michigan labor and material costs.
Every scope item is documented individually — no lump-sum estimates that are difficult for adjusters to review or approve.
Each estimate is supported by site photographs tied to specific line items, providing the evidence trail adjusters require.
Our initial estimates are structured to support supplement submissions if additional damage is found during the project.
Your Rights
Michigan law is clear: you are not required to use any contractor your insurance company recommends or prefers.
Allstate offers a "Good Hands" preferred contractor network and a program called Enhanced Claim Service (ECS). Under ECS, preferred contractors participate in a coordinated process where they may work directly with Allstate on estimate reconciliation and scheduling. Allstate presents this as a convenience.
Participation in Allstate's preferred or ECS network is entirely voluntary for policyholders. Michigan insurance regulations protect your right to select a licensed contractor of your choosing. Your policy benefits are the same regardless of which licensed contractor you use.
What the ECS program does offer Allstate is administrative efficiency and a contractor network that has agreed to certain pricing and process standards. What it offers you, as a policyholder, is convenience — not better outcomes by default.
When you choose Phase III Construction, you choose 33 years of Michigan roofing experience and a contractor who answers to you, not to a preferred network agreement. We bring our own Xactimate estimates, our own documentation standards, and our own relationship with Allstate's desk adjuster process — without being bound by a preferred contractor arrangement.
Choose Your Own Contractor — Start HereUnderstanding Your Payment
Most Allstate policies issue payment in two stages. Understanding both helps you make sure you collect everything you are owed.
ACV is the replacement cost of your roof minus depreciation. Depreciation is calculated based on the age and condition of your existing materials. This is the first check Allstate issues. It reflects what your roof was worth at the time of the storm — not what it costs to replace it today.
RCV is the full cost to replace your roof with like-kind and quality materials at current prices, with no deduction for depreciation. If your policy includes RCV coverage, you are entitled to the depreciation amount once repairs are completed. This second payment is called recoverable depreciation.
After Allstate issues your ACV payment, Phase III completes your repairs and provides documented proof of completion — invoices, photos, and a signed completion statement. We walk you through submitting this to Allstate to trigger the recoverable depreciation release. Many homeowners leave this second payment unclaimed. We make sure you do not.
Not all Allstate policies include RCV coverage. Some include ACV-only coverage, particularly on older roofs. We can help you read your declaration page and understand which coverage type you have.
Your deductible is subtracted from your ACV payment. Some policies carry a percentage-based hail deductible rather than a flat dollar amount. We review this with every homeowner before the project begins.
Allstate sets a time limit for claiming recoverable depreciation — typically 365 to 548 days from the date of loss, depending on your policy. Do not let this deadline pass unclaimed.
When the Scope Changes
A supplement is a request to revise the original claim estimate to account for items that were missed or damage discovered after the initial inspection.
Supplements are a normal part of the claims process. They arise when additional damage becomes visible during tear-off, when the original estimate omitted code-required line items, or when material or labor pricing needs correction. Allstate reviews supplements through its desk adjuster team.
During project execution, our crew documents any damage or required work that was not included in the original approved estimate. This includes decking damage, flashing requirements, code-mandated ice-and-water shield, and ventilation corrections.
We photograph the conditions requiring supplemental scope and note the specific Xactimate line items that apply. Documentation is tied directly to the physical evidence so Allstate's desk adjuster can verify the request without a re-inspection in most cases.
Phase III submits supplement requests directly to Allstate's desk adjuster team with a complete Xactimate-formatted line-item breakdown, supporting photographs, and a written explanation. We handle this communication directly so you do not have to navigate it alone.
Allstate's desk adjuster reviews the supplement package. Most well-documented supplements are resolved without requiring a site re-inspection. Once approved, the supplemental payment is issued to you and the project is updated accordingly.
Michigan Market Reality
Allstate commonly deploys independent (IA) adjusters in Michigan following storm events, particularly when claim volume is high.
An independent adjuster is a licensed claims professional who works for a third-party adjusting firm, not as a direct Allstate employee. They are contracted by Allstate to handle a portion of the claim workload. Their use of Xactimate and their documentation practices are generally aligned with Allstate's standards, but the level of detail and thoroughness can vary by firm and individual adjuster.
Phase III Construction has worked with a wide range of independent adjusters across southeastern Michigan. We know that the best outcomes come from clear, well-organized documentation that does not leave interpretation to chance. Our estimates and photo packages are built to stand on their own, regardless of who is reviewing them on the Allstate side.
Staff adjusters are Allstate employees. Independent adjusters are third-party professionals contracted by Allstate. Both use Xactimate. Both can approve supplements. The key difference is that IA firms vary in their consistency and documentation depth.
Whether Allstate sends a staff or independent adjuster, we recommend having a Phase III representative present during the inspection. This is the most effective way to ensure the scope reflects all visible damage.
Having a complete contractor estimate before or alongside the adjuster's inspection gives you a documented reference point for the scope. If items are missing from the adjuster's estimate, the gap is immediately identifiable.
