How to Read a Roof Insurance Estimate, Line by Line

What This Document Actually Is

When your adjuster finishes their inspection, they produce a document usually called a scope of loss or an estimate. It's the carrier's official position on what happened to your roof and what it should cost to fix it. The version you receive is typically generated in estimating software like Xactimate, and it follows a consistent structure from page one to the totals at the bottom.

Understanding that structure matters, because the estimate is almost never the last word on your claim. Contractors, desk adjusters, and even the original adjuster themselves will revise it as new information comes in. If you can read it, you can compare versions, ask informed questions, and spot the gaps that cost real money if they stay closed.

This walkthrough covers the standard layout most homeowners receive. Formats vary a bit by carrier, but the pieces below show up on nearly every roof estimate you'll see.

The Header: Your Claim's Identity Block

The first page is administrative — claim number, policy number, the named insured, the property address, the date of loss, and the name of the adjuster or inspector who wrote the estimate. It sounds boring, but treat it like the title page of a legal document: every later conversation, appeal, and supplemental request references that claim number.

Check two things here before you go further. First, make sure the date of loss matches the actual storm date. A wrong date of loss can complicate everything downstream, because coverage decisions hinge on what the weather did on that date. Second, confirm the property address is exactly right — including unit numbers or directions — since the estimate and the policy have to point at the same property.

Line Items: Description, Quantity, Unit Price

The heart of the estimate is a list of line items. Each line has a description of a task or material, a quantity, and a unit price, and quantity times price gives you the line total. The descriptions are often written in a shorthand that can look cryptic: "Remove/Replace" (often shortened to R&R) means the old material comes off and new material goes on. "Detach/Reset" means something is temporarily removed and reinstalled, like an AC unit sitting on a flat roof that has to be lifted so the roof can be replaced beneath it.

Quantities are measured in units that the roofing trade uses by default. Roofing is usually measured in squares, where one square equals 100 square feet of roof surface. So a line reading "10 squares of shingles" is describing 1,000 square feet of shingle work — not 10 square feet. Ridge caps, valleys, and flashing are often measured in linear feet (LF), and small accessories like vents are counted per unit (EA).

Unit prices come from the estimating software's price list, which is updated periodically by region. The price list is standardized, which is good for consistency, but it doesn't automatically account for your roof's difficulty — steep pitch, multiple stories, limited access, and premium materials all take more labor than the base price assumes, and those differences are where supplements often start.

The Common Categories You'll See

Most roof estimates are organized into a handful of categories. Learning to recognize them helps you notice when one is thin or absent entirely:

• Tear-off and removal. Stripping the old shingles, underlayment, and sometimes decking down to the structure. This is usually priced per square and may include debris disposal as its own line.
• Underlayment and accessories. Felt or synthetic underlayment, ice and water shield in valleys and eaves where code requires it, drip edge, and starter shingles. Ice and water shield is one of the most commonly missed lines.
• Shingles. The field shingles themselves, plus ridge caps. The line should specify the shingle type and weight (for example, 30-year architectural) — a vague "shingles" line with no grade attached is worth a question.
• Flashing. Step flashing at walls, chimney flashing, pipe jacks, and valley metal. Flashing lines are frequently underestimated or written as "detach/reset" when replacement is actually needed — old flashing that's been bent back during tear-off rarely reseats properly.
• Vents and penetrations. Ridge vent, turbine or static vents, bathroom exhausts. Each penetration through the roof should have a line for its boot or flashing.
• Gutters and miscellaneous. Detach and reset of gutters, fascia and soffit repair, paint where touched, and sometimes interior work if water got in.

O&P, Depreciation, and the Totals Page

Below the line items, you'll find a few summary sections that trip up almost everyone. The first is O&P — overhead and profit, typically listed as two 10% lines. In many claims involving complex roof work, the carrier adds O&P to the estimate. Whether your specific claim includes it depends on the carrier, the policy, and the complexity of the job, so check whether it's there rather than assuming.

Next are the depreciation columns. Your estimate will usually show each line's replacement cost value (RCV) — what the work costs new — alongside its actual cash value (ACV), which is the RCV minus depreciation for the age and wear of the existing materials. Depreciation on a 12-year-old roof is typically much heavier than on a 4-year-old one. We've written a full walkthrough of this mechanic in our guide to ACV vs RCV and recoverable depreciation, because it's the single most misunderstood page in the whole packet.

Finally, the totals: RCV total, total depreciation held, deductible, and the net amount payable — which is usually the ACV minus the deductible. That net figure is often the first check you receive. It looks small next to the RCV total, and that gap is normal: it closes when the work is completed and documented, not before.

How to Spot What's Missing

Adjusters work from what they can see on inspection day, often from the ground or a quick walk of the roof. That means the first estimate commonly misses things that only become visible during tear-off or that the inspection simply didn't catch. Items that frequently get left out:

• Ice and water shield in valleys or at eaves where local code requires it
• Drip edge on eaves and rakes
• Replacement (rather than reset) of step flashing, counter flashing, and pipe jacks
• Ridge vent replacement instead of a per-linear-foot "reset"
• Decking replacement — the estimate may include zero or a token amount of plywood, and the real number only emerges when the roof comes off
• Code upgrades required by the current building code that weren't in force when the house was built
• Interior repairs from water intrusion, if they weren't documented during the inspection

A missing line isn't a conspiracy — it's usually just the difference between a 45-minute inspection and a full tear-off. What matters is that someone compares the estimate against the actual roof and the local code, documents what's missing with good photographs, and asks for the estimate to be corrected through a supplement.
