A roofer may request an Xactimate supplement on a hail claim when the insurer’s initial scope leaves out necessary work, such as an ice-and-water barrier required by applicable local code. The key is not whether a bid is lowest, but whether every contractor is pricing the same complete scope.
Why an initial hail estimate may be incomplete
Xactimate is estimating software commonly used to price property damage. It can calculate a scope consistently only after the person writing the estimate has included the correct measurements, materials, labor operations, and job conditions.
That distinction matters because an initial estimate is not automatically a complete construction plan. An adjuster may work from a site visit and enter the items identified at that time. A roofing contractor may later identify work that is necessary to replace the roof properly or meet applicable requirements. A supplement is the documented request to add or revise those omitted items.
For homeowners, the practical issue is simple: compare scopes before comparing totals. Two estimates can use the same software and still arrive at very different amounts if one scope omits line items.
Ice-and-water barrier is a useful scope check
An ice-and-water barrier can be a major missing item in a cold-weather roof replacement scope. In one hail-claim example from Champlin, Minnesota, the initial estimate was for $9,000 and did not include an ice-and-water barrier; after the scope was revised, the estimate reached roughly $13,000 to $14,000.
That example does not establish what your insurer owes or what your local code requires. It shows why a homeowner should not assume the first number covers every part of the replacement. Requirements can depend on location, roof design, and the applicable building code.
- Local requirement: Confirm whether an ice-and-water barrier or another protective layer applies to your roof.
- Estimate treatment: Check whether the insurer’s scope includes the material, labor, and related installation operations.
- Scope difference: Identify whether the contractor is requesting an omitted item or pricing work differently from the original estimate.
What a supplement should do for your claim
A well-supported supplement should make the scope clearer, not merely increase a price. It should identify the missing operation, explain why it is needed for the planned work, and show how it changes the estimate.
The contractor may prepare the supplement directly or use a supplement company that works with Xactimate estimates. Some roofing businesses use outside firms for follow-up because communicating with desk adjusters and documenting revisions can take substantial time. That arrangement does not decide coverage.
Review the supplement for the item that was absent from the original scope and the reason it belongs in the revised one. If the request is vague, ask for a plain-language explanation and line-item detail before authorizing work based on it.
Why the lowest hail-claim bid can create a gap
A contractor may offer to do the job for the insurer’s original amount even when the scope appears short. That does not prove the scope is adequate. It can mean the contractor plans to use less costly accessories, accept a smaller margin, or take on work for less than the complete scope indicates.
The risk is that a number becomes the decision instead of the roof assembly. If a required item is not paid for and is not clearly included in the contractor’s price, that cost needs to be addressed before work begins. Do not rely on verbal assurances that the contractor will “take care of it.”
Compare the insurer’s estimate, the supplement, and the contractor’s proposal line by line before accepting a revised scope. Identify omitted items, confirm why each is needed, and make sure the proposed work reflects the same roof assembly described in the supplement.
A contractor who can explain a scope difference clearly is more useful than one who focuses only on the size of the insurance payment. Directorii lists verified contractors.
Keep the insurance estimate and roofing agreement separate
Your insurance estimate and the work you agree to have completed serve different purposes. The estimate describes the insurer’s valuation of damage under your policy, while the roofing agreement describes the work and price you accept.
Coverage and claim handling depend on your policy. A roofer can explain the roofing scope, but should not be treated as the final authority on policy coverage or legal rights.

FAQ
What is an Xactimate roof claim supplement?
An Xactimate roof claim supplement is a documented request to revise an insurance estimate after missing or additional roofing work is identified. It should show the specific line items being added or changed and why they are part of the planned roof replacement. It does not by itself determine what your policy covers.
Why would a hail claim estimate leave out an ice-and-water barrier?
An initial estimate may omit an ice-and-water barrier if the item was not entered into the original scope or was not identified during the adjustment process. Whether it is needed depends on applicable local requirements and the roof.
Should I hire the roofer with the lowest insurance claim bid?
Not until you confirm that the lowest bid covers the same complete scope as the other proposals and the insurance estimate. A lower number may exclude materials or operations that another proposal includes. Compare line items and omitted work instead of using the total alone.
Can my roofer submit a supplement to the insurance company?
A roofer may prepare and submit documentation describing roofing work that appears missing from an initial estimate. Some contractors also use supplement companies to handle estimate revisions and follow-up. Review what is being submitted because coverage decisions remain subject to your policy and insurer.
What should I compare between a supplement and my roofing proposal?
Compare the specific items added to the supplement with the work included in the roofing proposal. The supplement should identify why an item is needed, and the proposal should show whether that item is included in the work you are buying.
