How to Write an Xactimate Roofing Estimate That Actually Gets Approved

An approved estimate is one the adjuster can verify quickly and has no reason to cut. It does not mean the highest number. It means every line item ties back to a measurement, a photo or a building code, so the adjuster can say yes without a long back-and-forth.

Most reductions are not about the carrier being unfair. They happen because something on the estimate could not be verified in a few minutes: a quantity with no source, a charge with no explanation, or a component that was never mentioned. Your job is to remove those gaps before you submit.

This guide covers the estimate you write for the claim itself. If you are adding items after tear-off, read how to build an Xactimate roof estimate for insurance supplements and keep the Xactimate codes reference open while you work.

Every number on a roof estimate starts with measurements. If those are weak, everything built on them is easy to challenge.

Use a satellite or drone measurement report when you can, and confirm it with a few taped dimensions on the roof. Record these for each slope:

Attach the report or your field notes to the estimate. When the adjuster can see where each quantity came from, there is much less to argue about.

Adjusters review estimates top to bottom, usually slope by slope or trade by trade. A clean structure makes your estimate easier to approve because it matches how they check their own work.

A reliable order is: claim setup, roof sketch, main shingle items, accessories, charges, then overhead and profit. Document each step as you go so nothing depends on memory later.

Missing items are the most common source of lost revenue. A shingle line alone does not describe a roof replacement. Check that these are on your estimate when they apply to the job:

The Xactimate item names and codes for these are in our codes reference. Always confirm the exact item and unit price against your own price list, since codes and pricing change by region and by quarter.

Three adjustments cause more disagreement than any others.

Waste: Shingle waste depends on roof shape. A simple gable roof wastes less than a cut-up hip roof with many valleys. State the percentage you used and be ready to explain it. A single blanket number applied to every roof looks careless.

Pitch: Steeper roofs take more labor and carry extra charges in Xactimate. Record the pitch for every slope with a gauge in the photo, not just an estimate from the ground.

Height: Roofs on taller homes can qualify for an additional charge for the added difficulty. Note the number of stories and photograph the home from the street so the adjuster can see it.

Overhead and profit, usually shortened to O&P, covers the general contractor's cost of coordinating a job. It is commonly requested when a repair involves several trades, such as roofing plus gutters, siding, drywall or paint.

Carriers often resist O&P, so do not tack it on without support. List the trades involved, show that a general contractor is needed to coordinate them, and cite your policy language and state rules where they apply. Rules vary, so check what your state and the policy allow.

The estimate says what you want paid. The photos prove why. Every significant line item should have at least one labeled photo, and the labels should match the line item names so the adjuster can connect them instantly.

Take photos before anything is removed or covered, and keep the originals. Metadata such as time and location helps establish when and where the photo was taken. Our guide to hail damage roof inspections explains what to capture on the roof, and the roof inspection report guide covers how to organize it.

A five-minute review catches mistakes that cost you days later. Read the estimate as if you were the adjuster looking for a reason to question it, then work through the checklist below.

If you find a gap, fix it now. Once the estimate is submitted, every correction becomes a supplement and a new round of review.

Even a strong estimate can come back reduced. Do not accept the first number without reading the reasons. Compare the carrier's version to yours line by line and identify exactly what changed: quantities, items removed, or charges disallowed.

Respond in writing, item by item, and attach the photo or measurement that answers each cut. Our guide on what to do when a roofing supplement is denied walks through the appeal process, and how to write a roofing supplement shows how to document additional damage found during tear-off.

Here is how the steps fit together on a straightforward asphalt shingle replacement. The quantities are illustrative.

You measure a gable roof at 28 squares on a 6/12 pitch. You note two stories on the street side and photograph each slope. You choose the tear-off and install items for the shingle type on the roof, then apply a waste percentage appropriate for a simple gable roof. You add starter, ridge cap, drip edge, underlayment and ice and water barrier at the eaves and valleys, count the pipe jacks and vents, and add step flashing along the chimney. Then you apply any pitch or height charge that fits, attach the measurement report and photos, and review the checklist.

Nothing in that list is exotic. A good estimate is a complete and traceable version of ordinary work.

The estimate covers what is visible and known when the roof is inspected. The supplement covers what is found later or was left out.

A thorough estimate means a smaller, easier supplement. If you want the supplement side, read how to build an Xactimate roof estimate for supplements.

When only part of a roof is damaged, a common question is whether the carrier must replace more than the damaged area so the roof matches. The answer depends on the policy and on the rules in your state, and these disputes are common.

If matching is an issue on your job:

Keep the discussion factual. Photos and manufacturer information carry far more weight than opinion.

Carriers often use a mix of desk review, measurement reports and photo review. Understanding that helps you write estimates that pass quickly.

The lesson is consistent across all three. Make every number traceable, every item visible in a photo and every exception explained in a sentence.

Most estimate disputes come down to documentation. Photos are scattered across phones, notes get lost and nobody remembers which picture shows which damage.

Supplement Snap lets your crew capture photos from the roof, attach notes to each finding, and organize everything by project. It generates a supplement narrative and a PDF report you can send to the adjuster, so the evidence that supports your estimate is ready when the adjuster asks for it.
