What Should Be in a Roofing Estimate? 7 Red Flags
The difference between a $12,000 quote and an $18,000 quote on the same roof is almost never the contractor's greed — it's the scope of work underneath. Here's how to read a quote the way we do, so you can compare bids fairly and spot corner-cutting before you sign.
What a Good Quote Actually Contains
A legitimate roofing estimate is not a single lump sum. It's an itemized scope document that lets you verify exactly what work is being done. These are the line items that should appear on any quote you're willing to accept:
Roof measurement and pitch
The quote should state the roof size in squares (or square feet) and the pitch of each section. Without this, you can't verify any subsequent math. If the quote just says "your roof" without measurements, push for the numbers.
Tear-off scope
Specifically: number of layers to be removed (one-layer tear-off vs. two-layer tear-off) and disposal method. A layover (shingles applied over existing shingles) should be called out as such; it's cheaper but shortens the next roof's life and is only code-legal for one generation.
Deck inspection and replacement allowance
Every quote should address what happens if deck damage is found during tear-off. Most include an allowance for a certain number of sheets of plywood or OSB at a stated per-sheet rate. A quote that says nothing about deck replacement will hit you with a change order the day the roof comes off.
Underlayment specification
The specific product (e.g., "GAF Tiger Paw synthetic underlayment") and coverage area. Synthetic underlayment is current standard. 15-pound felt in 2026 is substandard.
Ice and water shield coverage
Ohio code requires ice and water shield at the eaves from the edge to at least 24 inches past the exterior wall line. A good quote specifies the coverage area in feet (e.g., "6-foot eave coverage") and whether valleys and penetrations also get ice and water.
Shingle product specification
Brand, line, color, and warranty term (e.g., "GAF Timberline HDZ, Charcoal, Lifetime Limited Warranty"). "Architectural shingle" without brand is not specific enough.
Flashing specifications
What gets new flashing (and what doesn't). Step flashing at sidewalls, apron flashing at front walls, counter-flashing at chimneys, pipe boots at plumbing vents. The quote should also address whether chimney counter-flashing is surface-applied (caulked to masonry) or cut into mortar joints (reglet). The second is correct.
Ventilation plan
Existing ventilation assessed and improvements spec'd. Ridge vent lineal footage, any soffit vent work, any additional roof vents. A quote that adds ridge vent without assessing soffit intake is a half-solution.
Cleanup and debris
Dumpster size and location, ground protection (plywood under the dumpster and walkways), magnetic sweep for nails, and cleanup frequency (end of day vs. end of job). Nails in the driveway after a roof tear-off are a real problem if cleanup isn't specified.
Warranties — both kinds
Manufacturer warranty on materials (term and type — standard vs. enhanced), and labor warranty from the contractor (typically 5 to 25 years depending on contractor). Both should be in writing. A labor warranty with no written documentation is a verbal promise and worth exactly as much.
Payment schedule
When deposits are due, progress payments, and final payment. A reasonable structure is 10-20% deposit at signing, progress payment at job start or partial completion, and final payment on completion. Anything that requires 50%+ up front before materials arrive is a red flag.
Permit responsibility
Who pulls the permit (contractor should) and who pays for it (typically included in the quote).
Proof of insurance and licensing
Ohio HIC (Home Improvement Contractor) registration number, general liability insurance certificate, workers' compensation certificate. The quote should reference these and the contractor should provide copies on request.
The 7 Red Flags
Red Flag #1: The lump sum with no line items
"Replace your roof — $14,500." That's not a quote, it's a number. Without itemization you can't verify scope. Ask for an itemized version. If the contractor refuses, move on.
Red Flag #2: The "waived deductible" promise
On insurance jobs, contractors sometimes offer to "take care of your deductible" or "make it disappear." This is insurance fraud under Ohio law (R.C. 3901.26) and puts you at legal risk as well. Any contractor making this offer is revealing how they do business.
Red Flag #3: Pressure to sign today
"This price is only good for 24 hours." "We have a crew in the neighborhood this week only." Legitimate roofing market conditions don't expire overnight. Pricing pressure is a sales tactic designed to prevent you from getting comparison bids.
Red Flag #4: Large upfront payment
Some deposit is normal (10-20% is typical). 50%+ before materials are delivered is not. Especially watch for "we need the full material deposit before we can order" — reputable suppliers extend credit to established contractors, they don't need homeowner cash to buy shingles.
Red Flag #5: No physical address
P.O. box only, out-of-state address, or a local address that's obviously a virtual office. A real contractor has a real shop in Central Ohio that you can drive to. Storm chasers set up during peak season and leave. If they're not there in three years when a warranty issue comes up, that warranty is worthless.
Red Flag #6: Unwillingness to show references or recent work
A legitimate contractor has current clients who'll take your phone call and recent jobs you can drive by. Someone who "doesn't share references" or "can't show you recent work" either doesn't have any or is new enough that they shouldn't be trusted with your $15,000 project.
Red Flag #7: The verbal commitment that's not in the quote
"We'll handle that." "We always do that — it's included." "Don't worry about it." Every commitment should be in writing. If they won't put it in the quote, it's not actually included and you'll fight about it later.
The bonus red flag: A contractor who can't or won't explain the "why" behind a line item they're recommending. If you ask "why do we need six feet of ice and water at the eaves?" and they can't answer clearly, they're not designing your roof system — they're just quoting boilerplate. You want someone who understands what they're recommending.
How to Use These Quotes to Compare Contractors
Once you have 2 or 3 itemized quotes, lay them out side by side. Go line by line:
Are the measurements consistent? Different squares on the same roof means someone measured wrong. Usually it's resolved with a satellite measurement tool (EagleView, Hover) that both can verify.
Are the underlayment and ice-and-water specs comparable? Synthetic vs. felt. 6-foot vs. 3-foot ice and water. Full valley coverage vs. minimal. These small differences matter over 25 years.
Are the shingle products comparable? GAF Timberline HDZ vs. Owens Corning Duration is apples to apples. GAF Timberline HDZ vs. an economy line is not.
Are the warranty terms comparable? A 50-year limited warranty with a 10-year labor warranty is different from a lifetime enhanced warranty with a 25-year labor warranty. Read the fine print.
Are the ventilation solutions comparable? Both quoting ridge vent? Both addressing soffit intake? Both including the same amount of linear footage?
When you've normalized the scope, you can compare the dollars honestly. Often you'll find the quotes are closer in cost than they first appeared — and the "cheap" quote was actually quoting less work, not cheaper work.
Questions to Ask Before You Sign
These are the questions that force the most honesty out of a contractor conversation:
"Will the same crew installing my roof have done at least 10 roofs together?" Crew consistency matters. Cobbled-together teams for peak season cause installation issues.
"Who will be my point of contact during the project, and will they be on-site?" A project manager who actually walks the job daily catches issues before they're buried.
"What happens if it rains during my project?" A real answer addresses tarp protection, timing decisions, and re-exposure. A hand-wave answer means they'll deal with it however it happens.
"Can I see the signed contract template before I commit?" Read the whole contract. Change-order procedures, warranty language, dispute resolution clauses — all matter.
"What's not included in this quote that a typical project ends up needing?" An honest contractor will name a few common additions (skylight replacement, chimney work, gutter replacement) so you can plan. A contractor who says "nothing, this is complete" is either lying or inexperienced.
Our quotes: Every line itemized, every specification named, every warranty in writing. If we can't explain it, we don't put it in the quote. We'd rather lose a bid to a cheaper competitor than win one by hiding scope. The homeowners who end up happy 10 years later are the ones who chose based on clarity, not price.
