Roofing Estimate Template: Line Items by the Square, Tear-Off and a Worked $14,364 Re-Roof

Updated November 10, 2026

By Moni Mindich, founder, 20 years in home improvement

A roofing estimate template needs one thing other trades can skip: a clear answer to what happens when the decking underneath turns out to be rotten. Price that as a per-sheet allowance up front and it stops being the argument on day two.

Quick answer: List the roof in squares with a stated waste factor, then tear-off, underlayment, ice and water shield, flashing, ventilation, disposal and a per-sheet decking allowance, followed by warranty, permit and payment terms. A worked 28-square, $14,364 re-roof follows the template.

What every roofing estimate should show

Show the measured squares, the waste factor and each layer of the system, because that is how a homeowner tells your bid from a cheaper one that skips ice shield. One square is 100 square feet of roof. Waste depends on the roof shape: a simple gable needs less than a cut-up hip roof with valleys, so write the percentage you used.

If three sheets of decking need replacing at $85, the customer already knows the total becomes $14,619. That single line prevents most day-two phone calls.

Insurance-claim estimates need one more step

On a storm claim, match your line items to the insurer's scope, because the adjuster compares them line by line. List the items the adjuster's scope missed, such as drip edge or starter course, as separate lines with photos. Do not offer to waive or absorb a deductible; several states prohibit it and it can put the claim at risk.

Three things that lose roofing bids

Most lost bids come from how the estimate reads, not the price:

  1. One lump number. It leaves the homeowner nothing to compare, so they compare the total.
  2. A slow send. The roofer who emails from the driveway has an advantage over the one who sends it Sunday night.
  3. No follow-up. Check back on day two and day seven, with one real reason each time, such as a material price holding until a stated date.

How do you write a roofing estimate?

Write a roofing estimate in six steps: measure the roof in squares, add a waste factor for the roof shape, price tear-off and disposal per square, list materials by line, add labor and any decking or flashing allowances, and finish with terms, an expiry date and a signature line.

  1. Measure in squares. One square is 100 sq ft of roof surface; use the pitch, not the footprint.
  2. Add waste. Simple gables need less than hips and valleys; write the percentage you used on the estimate.
  3. Price tear-off and disposal per square, per layer, plus the dumpster.
  4. List materials by line: shingles, underlayment, ice and water shield, drip edge, ridge cap, vents, flashing.
  5. Add labor and allowances: a per-sheet price for any rotten decking found after tear-off, so it is agreed before work starts.
  6. Close with terms: deposit, payment schedule, warranty, how long the price holds, and where to sign.

Roofing estimate vs quote vs proposal vs invoice

An estimate is your expected price, a quote is a fixed price, a proposal adds options and terms for the homeowner to sign, and an invoice bills work already done.

QuoteFixed for the scope listedWhen scope is certainAccepted in writing
ProposalFixed, often good/better/best optionsRe-roofs and bigger jobsYes, becomes the contract
InvoiceFinal amount owedAfter the work or at each payment stageNo

How do you measure a roof for the estimate?

Measure the roof area, pitch and every penetration before you write a number. Aerial measurement reports are accurate enough for most bids, but climb or inspect from a ladder anyway, because reports cannot show you soft spots, number of existing layers or poor flashing. Record the existing layers on the estimate: tear-off cost depends on it, and a second layer that was not priced is a common cause of a day-one change.

Pitch changes labor as well as safety. A walkable 5/12 and a steep 10/12 can have the same squares and very different crew days, so add a steep-pitch charge on its own line instead of hiding it in the per-square rate. Homeowners accept a charge they can see, and your crew gets paid for the harder work.

Good, better, best: should you offer options?

Yes, offer three options on the same measured roof, because it changes the question from "yes or no" to "which one". Keep the measurements and tear-off identical and change only the shingle line, underlayment and warranty. Homeowners can then see exactly what a higher price buys.

Do not make the bottom option something you would be embarrassed to install. If it skips ice shield in a climate that needs it, leave that option off. The cheapest line on your estimate still has your name on it when it leaks.

What terms protect you on a roofing job?

Put payment, weather and hidden damage in writing, because those three cause most disputes. State the deposit and final payment amounts, and check what your state allows for deposits on home improvement contracts. Say that weather can move the start date. Keep the decking allowance visible. Name who pulls the permit, and state who is responsible for gutters, skylights and satellite dishes that have to be moved.

Separate the manufacturer's warranty from your workmanship warranty, with the length of each. Homeowners tend to read "lifetime" as covering everything, and a clear line now is much cheaper than an argument in year eight.

When should you send and follow up?

Send it the day you inspect, and photograph what you found. A bid that arrives with photos of the actual failed flashing is far easier to believe than a number in an email. After a storm, the first complete estimate carries extra weight, so have your template ready before storm season rather than during it, and follow up on day two and day seven.

Common questions

What should a roofing estimate include?

Squares and waste factor, shingle system, tear-off, underlayment and ice shield, flashing and vents, disposal, a per-sheet decking allowance, warranty, permit and payment terms.

How do you calculate roofing squares for an estimate?

Divide the roof area in square feet by 100, then add a waste factor for the roof shape. A 2,500-square-foot roof is 25 squares; at 12% waste you order 28.

How do you handle rotten decking on a roofing estimate?

State a price per sheet on the estimate and replace it only with the homeowner's approval, so the extra cost is agreed before the tear-off starts.
