The detailed breakdown of repair costs your insurance company uses to calculate your settlement — and the document that determines whether your roof replacement gets fully funded or leaves you short.
What an Insurance Estimate Is
An insurance estimate is a line-item breakdown of the costs to repair or replace your storm-damaged roof — materials, labor, and related expenses — generated by your insurance adjuster using Xactimate software after their inspection of your property. It is the carrier’s calculation of what your covered loss is worth, and it becomes the basis of your settlement offer.
The estimate is not a final, unchangeable document. It is a starting point. On straightforward claims with limited damage, a well-prepared initial estimate may be reasonably complete. On complex claims — older roofs, multiple structures, solar systems, significant concealed damage — the initial estimate is almost always incomplete. Understanding what a complete estimate should contain, and how to identify what is missing, is one of the most practical skills a Colorado homeowner can develop before filing a roof insurance claim.
How Insurance Estimates Are Generated
The vast majority of insurance estimates in Colorado are produced using Xactimate — the industry-standard estimating software developed by Verisk. Xactimate calculates repair and replacement costs by combining a database of local pricing data — material costs, labor rates, and standard installation procedures updated regularly for each geographic market — with the measurements and specifications entered by the adjuster.
The accuracy of the resulting estimate depends entirely on two things: the completeness of the scope the adjuster entered and the accuracy of the measurements and specifications used. Errors in either category produce an underfunded estimate — and both types of errors are common in Colorado post-storm claims.
Types of Estimates in a Roof Claim
Multiple estimates may be generated during the course of a roof insurance claim, each serving a different purpose:
Insurance Adjuster’s Estimate
The carrier’s initial calculation of your covered loss, generated in Xactimate after the adjuster’s inspection. This is the document that produces your first settlement check. It reflects what the adjuster documented during their inspection — which may be complete, partially complete, or significantly incomplete depending on the adjuster’s thoroughness, the time spent on the inspection, and whether it was conducted in person or remotely.
Contractor’s Estimate
Your roofing contractor’s calculation of the actual cost to complete the required scope of work. A thorough contractor estimate identifies everything the insurance estimate should include — and typically identifies the gaps. When a contractor’s estimate is also generated in Xactimate, the comparison between the two estimates is straightforward — matching line items are easily confirmed and missing items are clearly visible.
Supplement Estimate
An amended estimate submitted to the carrier to add items missing from the initial scope. Supplements are a normal and expected part of the claims process on complex roofs. They may address items missed during the initial inspection, damage discovered during tear-off, or code upgrade requirements not included in the original scope.
Re-Inspection Estimate
A revised estimate generated after a field re-inspection when the initial estimate is significantly incomplete. Requesting a re-inspection with a professional inspection report documenting missed damage gives the carrier’s re-inspector specific items to evaluate and often produces a more complete revised estimate than supplement negotiations alone.
What a Complete Estimate Should Include
A properly scoped insurance estimate for a Colorado roof replacement covers every component of the roof system. Reviewing your estimate against this list identifies what is missing before you accept a settlement:
Tear-Off
Labor to remove existing roofing materials — shingles, underlayment, and in some cases decking. Should reflect the correct number of layers being removed and any steep-slope labor surcharge applicable to the roof’s pitch. Two-layer tear-offs cost more than single-layer and should be priced accordingly.
Decking Repair or Replacement
Replacement of damaged or deteriorated sheathing. Not always in the initial estimate — typically added as a supplement when damage is discovered during tear-off. Should specify the correct material at appropriate thickness.
Underlayment
Felt paper or synthetic underlayment installed over the decking beneath shingles. Many initial estimates default to felt paper — synthetic is the current standard and should be specified where applicable.
Ice and Water Shield
Self-adhering waterproof membrane at eaves, valleys, and penetrations. Required by Colorado code in specific situations. Should be a separate line item — not combined with underlayment — at the correct coverage area per applicable code requirements.
Drip Edge
Metal flashing at eaves and rakes. Required by the 2021 IRC in Colorado Springs. One of the most consistently missing line items in initial estimates on homes where it was previously absent. Should appear as separate line items for eaves and rakes measured in linear feet.
Starter Strip
First-course material at eaves and rakes. Should be purpose-made starter strip — not cut-down shingles. Frequently omitted despite being required by most shingle manufacturer warranties.
Field Shingles
The primary roof covering. Should specify the correct type — architectural, not three-tab, for most Colorado replacement work. Quantity should reflect calculated area plus appropriate waste factor for the roof’s complexity and pitch.
Hip and Ridge Cap
Pre-formed dimensional ridge cap for all ridges and hips. Should be priced separately from field shingles and specified as dimensional cap — not cut-down three-tab shingles.
Pipe Boots and Vent Collars
Individual replacement items for each penetration — plumbing vent boots, exhaust vent collars, and similar components. Should include one line item per penetration. Among the most consistently undercounted items in initial estimates.
Flashing
Step flashing, counter flashing, valley flashing, and kick-out flashing — each as separate line items with quantities reflecting actual linear footage on the roof.
Ventilation Components
Ridge vent, turbine vents, box vents, and other ventilation components. Damaged vents should be replaced. Code-required ventilation upgrades should appear as separate code upgrade line items.
Code Upgrade Items
All mandated upgrades required by current building code that were absent in the original installation — drip edge, ice and water shield, sheathing overlay, ventilation improvements. Should be clearly identified as code upgrade items under the ordinance and law provision.
Collateral Damage
Gutters, downspouts, siding, HVAC units, pipe boots, vents, and any other storm-affected property components. Should be included as separate line items with accurate quantities.
Secondary Structure Damage
Detached garage roofs, shed roofs, fences, and other Coverage B structures damaged in the same storm event. Should be scoped and estimated independently from the main dwelling.
Solar Detach and Reset
Professional removal and reinstallation of solar panel arrays to allow roof replacement. One of the highest-cost omissions on homes with solar and among the most consistently missed in initial estimates.
Overhead and Profit
General contractor overhead and profit on complex jobs requiring multi-trade coordination. Typically 10% overhead and 10% profit added to direct costs. Frequently absent on roofing estimates even when the project scope clearly warrants it.
Permit Fee
Building permit cost — a reimbursable expense under ordinance and law coverage. Routinely omitted from initial estimates despite being a legitimate, documentable project cost in virtually every Colorado jurisdiction.
How Estimates Differ Between Adjusters and Contractors
The gap between an adjuster’s estimate and a contractor’s estimate is one of the most common points of friction in Colorado roof claims. Several factors consistently drive the difference:
- Inspection thoroughness — a contractor who spends an hour on the roof identifies more damage than an adjuster who spends twenty minutes
- Material specifications — contractors specify current replacement standards; adjusters sometimes default to lower-grade specifications that understate actual replacement cost
- Measurement accuracy — contractor measurements from the roof surface are more accurate than satellite-derived adjuster measurements, particularly for pitch and complex geometry
- Code knowledge — contractors operating under current PPRBD or PRBD requirements know which code upgrade items are mandatory; adjusters working remotely may not
- Scope completeness — contractors include every component required for a complete, warranty-compliant installation; adjuster estimates frequently omit components that are required but not visible during inspection
Reading Your Estimate Effectively
When you receive your insurance estimate, review it systematically before accepting any payment as final:
- Check the roof measurements — total squares, eave length, ridge length, valley length, hip length, and rake length should match your contractor’s field measurements
- Check the pitch — find the pitch listed for each roof section in the estimate diagram and compare to your contractor’s field measurements. Underestimated pitch produces underfunded labor calculations.
- Review every line item — compare the estimate against the complete scope checklist above. Each missing item is a supplement opportunity.
- Verify material specifications — confirm that shingle type, underlayment type, and ridge cap type match the correct replacement standard
- Check for overhead and profit — confirm O&P is present on complex jobs requiring multi-trade coordination
- Confirm permit fees are included — a permit line item should be present on every Colorado roof replacement estimate
Common Estimate Questions
Can I negotiate my insurance estimate?
Yes — and you should when it is incomplete or inaccurate. The estimate is a starting point, not a final determination. Submitting a documented supplement package that identifies specific missing line items with supporting measurements, photographs, and code citations is the standard process for increasing an inadequate initial estimate. This is not adversarial — it is the normal claims process on any complex roof.
My contractor’s estimate is significantly higher than the insurance estimate. What does that mean?
It typically means one or more of these things: the insurance estimate is missing line items, using incorrect measurements, specifying lower-grade materials, or using pricing that does not reflect current local market rates. The gap is the starting point for a supplement negotiation — not an indication that your contractor is overcharging. A contractor who can identify specific line item differences and document them clearly gives you the strongest position in that negotiation.
How long do I have to negotiate my estimate before accepting a settlement?
Your policy’s statute of limitations — generally one to two years from the date of loss in Colorado — governs the outer boundary for pursuing your claim. However, internal policy deadlines like the proof of loss requirement may apply on a shorter timeline. There is no hard deadline for supplement negotiations beyond these constraints, but acting promptly is practical — the longer you wait, the more difficult causation becomes to establish for items discovered during tear-off.
Does the insurance estimate include sales tax on materials?
It should — Xactimate includes sales tax as a separate line item in properly constructed estimates. If your estimate does not include sales tax on materials, that is a supplement item worth raising. Colorado’s sales tax rates vary by jurisdiction and are a legitimate component of the true replacement cost.
How Claim Advocacy Helps With Insurance Estimates
The estimate review is the highest-leverage point in the entire claims process. Every missing line item identified and supplemented before settlement is money that stays in your pocket rather than becoming an out-of-pocket gap you absorb after the project is complete.
- Estimate review — systematically comparing the carrier’s estimate against a complete field inspection to identify every missing line item, measurement error, and specification discrepancy
- Supplement preparation — documenting missing items in Xactimate format with supporting evidence that carriers can review and approve efficiently
- Pitch and measurement verification — comparing satellite-derived measurements in the estimate against field measurements and documenting discrepancies
- Material specification correction — identifying default specifications that understate actual replacement cost and documenting the correct standard
- Code upgrade documentation — adding code-required items with references to applicable PPRBD or PRBD code provisions
- Pricing verification — confirming that estimate pricing reflects current local market rates and documenting divergence when it does not

Think Your Estimate Is Missing Something?
Most initial insurance estimates on Colorado roof claims are incomplete — not because carriers are acting in bad faith, but because adjusters working under time pressure miss things that a thorough field inspection would catch. A free inspection gives you an independent line-item comparison so you know exactly what your estimate should contain before you accept a settlement.
