How to Read a Roofing Estimate and Spot Red Flags Before You Sign

By Michael Matthews, Twin County Construction · Germanton / Winston-Salem, NC

Short answer: A trustworthy roofing estimate is written, itemized and specific: it names the materials by brand, says whether the old roof comes off, and spells out underlayment, flashing, ventilation, permits and warranty. If a roofer won’t put that in writing, pressures you to sign today, wants cash up front or can’t show you a North Carolina license and proof of insurance, walk away.

What a roofing estimate should include, line by line

Whether the quote comes from us or another Winston-Salem roofer, every line below should appear on a full replacement quote, in writing. If a line is missing, ask about it before you compare prices; a cheaper bid often just leaves something out.

Line item	What it means	What a good estimate says
Roof size	Roofs are measured in “squares” (1 square = 100 sq ft)	The number of squares, plus a waste allowance
Tear-off and disposal	Removing old shingles down to the wood deck	How many layers come off, and that debris is hauled away
Decking repair	Replacing rotten or soft plywood under the shingles	A price per sheet, so you know the cost if rot is found
Underlayment	A water-resistant layer between the deck and shingles	The type (synthetic or felt) and brand
Ice and water shield	A sticky waterproof membrane for leak-prone spots	Where it goes: valleys, eaves, around chimneys and vents
Drip edge and starter strip	Metal edging and the first row that seals the edges	Both listed, not assumed
Shingles and ridge cap	The visible roofing	Brand, product line and color by name
Flashing	Metal that seals where the roof meets walls, chimneys and pipes	New flashing and pipe boots, or which pieces are reused and why
Ventilation	Intake (soffit) and exhaust (ridge or box vents) that let the attic breathe	What vents are installed or replaced
Permits	Local building permit, where required	Who pulls it, and whether its cost is included [verify Forsyth/Guilford reroof permit rules]
Cleanup	Removing nails and debris from your yard	A magnetic nail sweep and final cleanup
Warranty	Manufacturer (materials) plus contractor (workmanship)	Both, with their length in years and in writing
Payment terms	When and how you pay	A deposit amount, a final payment due at completion, and accepted payment methods

Roofing estimate red flags to watch for

A vague estimate is the easiest place for surprise costs to hide. Watch for:

One lump-sum price with no breakdown of materials and labor.
No brand or product line for shingles or underlayment, just “architectural shingles.”
“Roof over” without saying so. Laying new shingles on top of old ones skips the deck inspection and can affect warranty coverage.
No decking price. Without a per-sheet price, rotten wood found mid-job becomes whatever the roofer says it costs.
Flashing “as needed” or not mentioned at all.
No mention of permits or who is responsible for them.
A warranty that is only spoken, not written on the contract.
A price far below every other bid. Ask what’s missing before you celebrate.

For a second opinion, the FTC’s guide to avoiding home improvement scams and the National Roofing Contractors Association’s advice on selecting a roofing contractor are both worth a read.

Hidden costs: contingency fees, change orders and the final price

An estimate is a starting price. The final bill can change for a few honest reasons, mostly because of what the crew finds once the old shingles come off. A good estimate tells you up front how those changes will be priced, so nothing on the final invoice is a surprise.

Rotten decking. Priced per sheet on the estimate. Ask the crew to show you the bad wood before they replace it.
Extra layers. If a second layer of shingles turns up during tear-off, the estimate should say what that costs per square.
Contingency fee or allowance. A set amount held for unknowns. Ask what it covers, whether unused money comes back to you, and get the answer in writing.
Change orders. Any added work should be written up and signed by you before the crew does it, not added to the final bill afterward.

A simple rule: if it isn’t on the estimate or a change order you signed, you shouldn’t be paying for it.

Storm chaser warning signs

After hail or high winds roll through the Triad, out-of-town crews often go door to door. The NC Department of Insurance tells homeowners to be suspicious of any roofer who shows up unsolicited after a storm. Watch for:

“Today only” pricing or pressure to sign before they leave your driveway.
Cash only, or a big payment up front. NCDOI says a small deposit of 10–20% may be standard, but most of the payment should come after the work is done.
No NC license or proof of insurance, or a promise to “send it later.”
A “free inspection” that always finds damage. NCDOI warns that some fake inspectors invent damage to push quick repairs.
Offers to handle your insurance claim for you. The NC Insurance Commissioner advises dealing with your insurance company yourself.
Out-of-state plates, a temporary phone number or no local address. The Commissioner has flagged out-of-state crews as a warning sign.

Storm damage? Call your insurer first. NCDOI recommends asking for an adjuster to inspect your roof before anyone else goes up there.

You have some protection. Under a newer North Carolina law, if you sign with a roofer and your insurance then denies the claim, you have five days to cancel without penalty, and the roofer can’t do work or collect more money. [verify current statute and wording]

How to read an insurance estimate for storm damage

If your insurer is paying for the roof, you’ll get two estimates: one from your roofer and one from the adjuster. The adjuster’s version is often written in software called Xactimate, so it looks different. These are the terms that matter most:

Replacement cost value (RCV): what the insurer says the full job should cost.
Depreciation: an amount held back because of the roof’s age.
Actual cash value (ACV): RCV minus depreciation. On many policies this is the first check you receive.
Recoverable depreciation: on replacement-cost policies, the held-back amount is often paid once the work is done and the final invoice is sent in. Check your policy.
Deductible: your share. It comes off the payout, and you pay it. Any roofer who offers to “cover” or waive it is a red flag.

Line the adjuster’s estimate up against your roofer’s, item by item. Drip edge, starter strip, ice and water shield, ridge cap, permits and steep-roof charges are common things to check. If something is missing, ask your adjuster to review it. A roofer can provide photos and measurements, but the NC Insurance Commissioner advises homeowners to handle the claim themselves.

How to check a roofer’s NC license and insurance in two minutes

North Carolina doesn’t issue a separate roofing license. Instead, any contractor on a project of $40,000 or more must hold a general contractor license from the NC Licensing Board for General Contractors (NCLBGC). Many re-roofs cost less than that, so a roofer without a license isn’t automatically breaking the law. But a license is still a strong sign the company has met state requirements and answers to a board.

Check a license:

Go to the NCLBGC website and use the license search.
Search by the company’s legal name or license number.
Confirm the license is active and the name matches the contract.

If a company isn’t listed, it may trade under a different legal name or only take jobs under $40,000. Ask; don’t assume.

Check insurance: ask for certificates of general liability and workers’ compensation insurance, and call the insurer to confirm they’re active. Without coverage, an injury on your roof could become your problem. NCDOI lists both as things to verify in writing.

[TCC: add TCC’s NC general contractor license number here as the example.]

Before-you-sign checklist

☐ I have 2–3 written, itemized estimates to compare (NCDOI recommends at least two or three)
☐ Each estimate names the shingle brand, product line and color
☐ Tear-off, underlayment, ice and water shield, flashing and ventilation are all listed
☐ There’s a per-sheet price for decking repairs
☐ I know who pulls the permit
☐ The license is active on the NCLBGC site (or I know why the roofer isn’t listed)
☐ I’ve seen current liability and workers’ comp certificates
☐ The deposit is small, and most payment is due after the work is done
☐ Both warranties (materials and workmanship) are in writing
☐ For storm damage, my insurance adjuster has already inspected the roof
☐ Any contingency fee or allowance is explained in writing, and added work needs a change order I sign
☐ For an insurance job, I’ve compared the roofer’s estimate to the adjuster’s line by line

What a real Twin County estimate looks like

[Placeholder: a redacted TCC estimate from a recent Triad job (customer name and address removed), with callouts pointing to each line from the table above. Add one sentence per callout, e.g. “Here’s where we list the ice and water shield in the valleys.” No other local roofer shows a real estimate, so this is the part of the post most likely to get noticed and quoted.]

FAQs

How much deposit should a roofer ask for? NCDOI says a small deposit of 10–20% may be standard, with most of the payment due after the work is finished. Be wary of anyone asking for full payment or a large deposit before work starts.

Does a roofer need a license in North Carolina? A general contractor license is required for projects of $40,000 or more. There’s no separate state roofing license, so smaller jobs may be done legally without one. Hiring a licensed contractor is still the safer choice.

Why are two roofing estimates so different? Usually because they don’t include the same things. Line them up item by item: tear-off, underlayment, flashing, ventilation, decking and warranty.

Should I let a roofer handle my insurance claim? The NC Insurance Commissioner advises dealing with your insurance company yourself. A good roofer can still document damage and meet with your adjuster.

Where do I report a roofing scam? Contact the NC Department of Insurance Criminal Investigations Division. [verify current phone number on ncdoi.gov]

What do “tear-off” and “disposal” fees mean on a roofing estimate? Tear-off is the labor to strip the old shingles and underlayment down to the wood deck. Disposal is the dumpster and hauling to get that debris off your property. Both are normal on a full replacement. The estimate should say how many layers are coming off, since a second layer adds cost.

What does a contingency fee on a roofing estimate mean? It’s money set aside for problems no one can see until the old roof is off, like rotten decking. Ask what it covers, how it’s priced and whether you get back what isn’t used.

What warranty terms should a roofing estimate include? Two warranties, both in writing: the manufacturer’s warranty on materials and the contractor’s workmanship warranty on the installation. Look for the length of each, what voids them, whether they transfer if you sell, and who registers the manufacturer warranty.

How do I compare material and labor costs between two estimates? Ask each roofer to split materials and labor, then compare price per square (100 square feet) for the same shingle line. If one bid is much cheaper, check whether it leaves out underlayment, flashing, ventilation or decking.

Are there financing options or senior discounts I should ask about? Ask before you sign; many roofers offer payment plans or seasonal discounts. Homeowners 62 or older with very low income in eligible rural areas may qualify for the USDA Section 504 Home Repair program. [TCC: add current financing/discount details or remove this line.]

How can I tell if a roofer is exaggerating damage? Ask for photos of every problem and where it is on your roof, and get a second written estimate. Our guide to [repair or replace: 7 signs you need a new roof — link once live] explains when a repair is all you need.
