How to Compare Roofing Quotes, Line by Line

A line-item template for comparing roofing estimates like for like - tear-off, underlayment, decking allowance, flashing, disposal, permit, warranty and payment terms.

Roofing quotes can only be compared when they describe the same job. Two quotes for "a new shingle roof" can be far apart because one includes tearing off two old layers, replacing rotten decking, new flashing and a permit, and the other prices a lighter job and leaves those items for later. The way to compare them is to put every quote into the same line items before you look at the totals.

The Federal Trade Commission says a written estimate should describe the work to be done, the materials, the completion date and the price 1. The National Roofing Contractors Association (NRCA) adds a roofing-specific list: the type of roof covering with its manufacturer and color, the scope of work, removal or replacement of the existing roof, flashing and ventilation work, the installation method, start and completion dates, payment procedures, and the length of the warranty and what it covers 2. The template below turns those lists into rows you can fill in.

Why roofing quotes are hard to compare

A roof price is built from a handful of decisions that a short quote may not spell out:

  1. The material and product line. Asphalt, metal, tile and slate are priced very differently, and within asphalt shingles a manufacturer sells several lines at different price points. NRCA notes that every roofing material comes in different grades with corresponding prices 2.
  2. What happens to the old roof. A full tear-off down to the deck costs more than covering the existing roof, and a second old layer adds labor and disposal. Fixr reports that tear-off and disposal average about $50 per roofing square (100 square feet), including dumping fees, and can reach $150 per square for heavy materials such as concrete tile or multiple layers of shingles 4.
  3. The deck under the shingles. Nobody can see the condition of the decking until the old roof is off. Fixr puts decking replacement at $2 to $8 per square foot 4. A quote that is silent on decking has not priced it.
  4. Labor and access. Fixr says labor makes up 40% to 60% of a roof replacement, and that it moves with how hard the old roof is to remove, how complex the roof is and local labor rates 4. Steep pitches, many valleys, skylights and chimneys all add time.

Around those sit the line items that are easy to leave out: flashing, ventilation, drip edge, the permit, and cleanup.

The line-item template

Ask each company to fill in, or confirm, every row. Where a quote is silent, write "not stated" and ask.

Line itemWhat to write downWhy it matters
Company detailsLegal name, address, phone, and any license or registration number with its issuing bodyLets you check the company with your state or city
Roof areaNumber of squares measured, and how waste is countedConfirms each quote prices the same roof
Roof coveringMaterial, manufacturer, product line and colorLines within one brand differ in build and warranty
Tear-offFull tear-off or a layer over the existing roof; number of old layers removedChanges labor, disposal and what the crew can inspect
DeckingPrice per sheet or per square foot if rotten decking is found, and an included allowanceAvoids an open-ended change order once the old roof is off
UnderlaymentFelt or synthetic; where ice-and-water membrane goes (eaves, valleys)Part of the water barrier under the shingles
FlashingNew or reused at chimneys, walls, valleys and ventsA common leak point when old metal is reused
VentilationRidge vent, box vents, intake at the soffits; what is added or replacedSome shingle warranties depend on it 2
Drip edge and starterIncluded or notSmall items that some quotes skip
Disposal and cleanupDumpster, haul-away, magnetic nail sweepSome companies charge separately
PermitWho applies for it, and whether the fee is in the priceRequirements vary by city

Checking the totals against a published range

Once the rows match, a published range can show whether a quote is in an ordinary band or far outside it. Fixr reports a national average of about $10,000 for a roof replacement, with most jobs between $7,500 and $14,000, and an average of $4.75 per square foot within a range of $3.75 to $11 4. Fixr says it builds these figures from pricing databases, contractors and industry experts, and its material table assumes a home with roughly 2,000 square feet of roof 4. Your roof's size, pitch, material and location can put a fair quote well outside that range, so treat it as a sense of scale. The roof replacement cost guide covers the cost drivers in more depth.

The same source helps with the hidden lines. Fixr puts permit fees for a roof replacement at $100 to $500 in most cities 4, so a quote that says "permit included" should account for that cost somewhere.

When one quote is much lower

Before choosing a low quote, check which rows it leaves out. A lower total often means a layer over the existing roof where others quoted a tear-off, reused flashing, no decking allowance, a different product line, or disposal billed separately. The Texas Attorney General's office warns that a bid far below the others may leave out tasks you expected, or rely on cheap labor or second-rate materials, and notes that most legitimate bids fall into a fairly close range 5. NRCA's advice points the same way: keep a healthy skepticism about the lowest bid, because price is only one criterion 3.

Ask the low bidder to price the missing items in writing so the totals line up. If it cannot or will not, that tells you something too.

The payment line

The payment schedule deserves the same attention as the price. The FTC advises against paying the full amount up front and against making the final payment until the work is done and you are satisfied, and it notes that some states cap the down payment 1. Florida is one example of a state with a rule tied to deposits: a contractor who takes more than 10% of the contract price as an initial payment on a residential job must apply for any needed permits within 30 days and start work within 90 days after the permits are issued, unless the homeowner agrees in writing to a longer period (Florida Statutes 489.126) 6. Check your own state's consumer protection office for local rules.

Questions to ask every company

  • Will you remove all old layers, and how many do you expect to find?
  • What is the price per sheet if decking has to be replaced, and how will you show me the damaged areas?
  • Which manufacturer warranty tier is included, and do you register it?
  • How long is your workmanship warranty, and is it in writing?
  • Who applies for the permit?
  • Who will supervise the job on site? NRCA suggests asking for that person's name and how many workers will be on the roof 3.

The pillar guide on how to choose a roofing contractor covers checking the company itself, and roof warranties explained and roofing contract red flags cover the paperwork. RooferProMatch is a lead-generation service, not a roofer, and is paid by roofing companies when a reader requests quotes. If you want more quotes to put in the template, you can compare quotes from roofing companies in your area.
