Two proposals, side by side
Compare two roofing quotes before you choose one.
Two roofers measured the same roof and produced totals thousands apart. Before deciding which is the better value, it is worth establishing whether they are describing the same job — because on roofing, they usually are not.
Learn The Quote Compare reads both written proposals together and sets them against each other: squares and waste, layers removed, underlayment package, flashing, ventilation, decking terms and warranty tier.
We do not name a winner, rank roofers or judge whether either price is fair. We make the documents comparable so the decision is yours to make on real information.

What should be in the quote
What a clear roof_compare quote normally covers.
Every contractor writes proposals differently. These are the details homeowners most often want to see spelled out before signing — a missing item is not automatically a problem, but it is usually worth a question.
- Square count and measurement method for each
- Waste factor assumption in each
- Layers removed in each tear-off
- Shingle brand, line and wind rating for each
- Underlayment product in each
- Ice and water shield coverage in each
- Starter and ridge products
- Drip edge material and gauge
- Valley method used by each
- Flashing: new versus reused
- Pipe boots and vents
- Decking unit price in each
- Nail type and pattern
- Ventilation plan in each
- Skylight and penetration handling
- Gutter, solar and satellite handling
- Property protection and cleanup commitments
- Dumpster and disposal
- Permit and inspection in each price
- Manufacturer warranty tier and requirements
- Workmanship warranty term for each
- Payment schedules and exclusions
Line-item breakdown
What each line on the estimate actually pays for.
| Line item | What it covers | What moves the number |
|---|---|---|
| Quantity | Measured squares plus waste allowance. | Measurement method and whether waste sits inside the stated figure. |
| Tear-off | Layers removed and hauled away. | Layer count, pitch, height and disposal weight. |
| Underlayment package | Felt or synthetic plus ice and water membrane placement. | Product grade and how much of the roof receives the membrane. |
| Shingle line | Covering plus starter and ridge accessories. | Product tier and wind rating. |
| Flashing and details | Wall, chimney and valley metal, boots and vents. | New versus reused, and cricket inclusion at wide chimneys. |
| Ventilation | Ridge or box exhaust plus intake corrections. | Reuse, replacement or redesign to satisfy warranty terms. |
| Decking terms | Unit price and approval process for replacement sheathing. | Whether a price exists at all before work starts. |
| Warranty tier | Product coverage plus workmanship coverage. | Accessory requirements, installer certification and duration. |
A higher price is not evidence of overcharging, and a lower price is not automatically a better deal. Two estimates can differ because they describe genuinely different work.
Commonly missing or unclear
The gaps homeowners notice after work has started.
- One proposal states squares, the other does not.
- Waste factor unstated on both.
- Layer counts differ with no explanation.
- Underlayment named generically on one.
- Ice and water shield only in one scope.
- Flashing reuse implied rather than stated.
- Decking excluded on one with no unit price.
- Ventilation unaddressed on both.
- Permit included in one price only.
- Warranty tier claimed without accessory requirements.
- Workmanship warranty absent from one document.
- Neither lists exclusions.
Allowances, exclusions and extras
Where the final invoice can drift from the estimate.
Decking discovery
Both proposals face the same unknown. Compare unit prices and approval steps, not just mentions.
Hidden layers
If one quote assumed one layer and there are two, its total will move.
Chimney condition
Masonry work may sit outside both roofing scopes.
Ventilation requirements
An enhanced warranty may require intake work neither proposal priced.
Interior repairs
Prior leak damage inside the home is usually excluded from both.
Detach and reset
Solar and satellite equipment handling may differ between proposals.
Questions to ask
Ask these before you sign.
- 1How many squares did each of you measure, and by what method?
- 2Is waste included in that square figure?
- 3How many layers does each price assume?
- 4What underlayment, and where does ice and water shield go?
- 5Which flashings are new in each scope?
- 6What is each per-sheet decking price?
- 7What ventilation work does each include?
- 8Which manufacturer warranty tier, and what does it require?
- 9Is the permit included in each price?
- 10What workmanship warranty does each of you provide?
- 11What protection and cleanup are committed to?
- 12What does each proposal exclude?
Quote red flags
Wording that deserves a second look.
- A quote that cannot be compared because it states no quantities.
- Pressure to sign before the second proposal arrives.
- Offers to match a competitor's price without matching scope.
- Written claims about insurance outcomes.
- Deductible-covering offers.
- A deposit demanded during the comparison stage.
- Enhanced warranty claimed with no accessories listed.
- No exclusions section in either document.
None of these mean a contractor is doing anything wrong. They are simply points where the written document leaves room for interpretation.
Comparing competing estimates
Are the two bids even for the same job?
- Normalize quantity before comparing totals.
- Compare layer counts for tear-off.
- Compare underlayment and membrane coverage.
- Compare shingle tier and wind rating.
- Compare flashing replacement scope.
- Compare ventilation plans.
- Compare decking unit prices.
- Compare workmanship and product warranty terms.
What affects pricing
Labor rates, material costs, project complexity, geography, permitting, site access, specifications and current market conditions all move the number. There is no single universally correct price for a job, and Learn The Quote does not claim to determine one.
Measured quantity
Squares and waste account for the largest share of any roofing total.
Material package
Underlayment, membrane and shingle tier differ substantially in cost.
Detail work
Valleys, dormers, chimneys and skylights add labor per square.
Warranty tier
Enhanced coverage requires specific accessories and certified installers.
Disposal and access
Layer count, landfill rates, pitch and height all move labor cost.
Local demand
Post-storm capacity constraints affect price and schedule regionally.

How Learn The Quote helps
An independent read of the document you already have.
Upload your quote
Upload the written roof_compare estimate you already received. Your first Quote Snapshot is free.
We read it closely
We organize the proposal in plain English and flag items that look unclear or potentially missing.
You ask better questions
You get price context and specific questions to put to your contractor before you sign.
Learn The Quote is informational and document-based. We do not issue price verdicts, we cannot tell you a universally correct price, and this is not a substitute for licensed trade, engineering, legal or financial advice or for an onsite inspection. We are not a contractor marketplace and we do not sell your details.
How Compare works
What the $59 Compare service produces for two roof quotes.
Upload both proposals and we read them together. You receive a written comparison: what each document appears to include, where the two scopes diverge, what each leaves unstated, and one consolidated question list you can send to both roofers.
We do not tell you which roofer to hire. Reputation, references, scheduling and how each company handled your questions all matter, and none of that lives in the estimate.
If the second proposal has not arrived yet, start with the free Quote Snapshot on the one you have.
Normalizing the numbers
Making two roofing totals genuinely comparable.
- Get both square counts and confirm whether waste is included.
- Match layer counts for tear-off.
- List the underlayment and membrane in each.
- Note which flashings, boots and vents are new.
- Record decking unit prices from both.
- Compare ventilation scope against warranty requirements.
- Then, and only then, compare price.
Questions homeowners ask
Frequently asked questions
- How should I compare two roofing quotes?
- Start with quantity. Compare square counts and waste, then tear-off layers, underlayment package, flashing treatment, ventilation, decking unit prices and warranty tier. Compare totals last, once you know what each covers.
- The square counts are different. Which is right?
- Either could be, and both might be defensible. Measurement methods differ, waste is handled differently, and one contractor may include areas the other excluded. Ask each how they measured and whether waste is inside the figure.
- One quote is much cheaper. What is usually missing?
- Frequently: fewer squares, felt instead of synthetic underlayment, no ice and water shield, reused flashing and boots, existing ventilation left alone, decking excluded, or a standard rather than enhanced warranty.
- Does the cheaper quote mean worse work?
- Not necessarily. It may mean a smaller scope, lower overhead, or a crew with less warranty backing. The document tells you which of those is likely — the price alone does not.
- How do I compare warranties?
- Separate the manufacturer's material coverage from the roofer's workmanship warranty. Compare durations, what voids coverage, whether it transfers on sale, and which accessories or certifications the enhanced tier requires.
- What about decking replacement?
- Compare unit prices per sheet rather than whether decking is mentioned. A quote with no unit price has an open ending, regardless of how the total looks today.
- Will you tell me which roofer to hire?
- No. We do not recommend or rank contractors and we do not determine market value. We show you what each document covers, where they differ, what each omits and what to ask before deciding.
- What do I upload?
- Both written roofing proposals for the same roof. The $59 Learn The Quote Compare service is designed for exactly two. With only one proposal, start with the free Quote Snapshot.
- My roof involves an insurance claim. Can you still compare?
- We can compare what the written documents contain, including line-item formats. We do not verify coverage, interpret policies, or act as a public adjuster or attorney.
- Is my information shared with roofers?
- No. We do not contact contractors, take referral fees or sell your details. Uploads stay private.
