Testing A Number

Is $15,000 Too Much For A New Roof?

Unanswerable as asked, and answerable in about ten minutes once you add three facts about your roof. Here is how to run that test on any figure.

A price is not high or low in isolation. Fifteen thousand dollars could be an excellent price for a large, steep, cut-up roof with two layers coming off and full decking replacement, and a poor price for a small single-storey gable with one layer and sound decking. Nobody can tell you which of those you have without the numbers. This page gives you the test rather than a verdict.

Why The Question Cannot Be Answered As Asked

Every roofing figure carries three hidden variables: how much roof, how hard to work, and what is included. Change any one and the same dollar figure moves from generous to excessive.

This is also why asking neighbours or the internet produces such contradictory reassurance. Your neighbour's roof might be half the squares at a third of the pitch with sound decking. The number they paid tells you very little, and can do real harm by anchoring you to an expectation your own roof cannot meet.

The Three Facts You Need First

Fact 1

Your square count

Footprint under the roof, plus overhang, multiplied by pitch factor, divided by 100. Our page on converting house size to roof size walks it through. Without this, no price can be evaluated.

Fact 2

Your complexity and layer count

How many valleys, hips, dormers, chimneys and skylights, and how many layers of old roofing are coming off. Both drive labor and disposal.

Fact 3

What the quote actually includes

Underlayment type, ice-and-water placement, new or reused flashing, pipe boots, ventilation work, decking per-sheet price, permit, cleanup, and the written warranty.

The Test

Judging any quoted figure

1. Quote total / your square count= price per square
2. Compare against your other written bidssame roof, same measurement
3. Line up the scope of eachthe checklist in Fact 3
4. Adjust for pitch, layers, accesslegitimate cost drivers
5. Identify what the outlier omitted or addedusually explains the whole gap
Verdictreasonable, or reasonable for less roof

Notice what the test does not use: a national average, a neighbour's price, or a figure from a cost model. It compares real written bids on your actual roof against each other. That is the only comparison with any predictive power.

When A High Number Is Actually Correct

Some roofs genuinely cost more, and a contractor pricing them honestly will look expensive next to one who has not accounted for the difficulty:

  • Steep pitch requiring fall protection and slowing installation substantially.
  • Two or more layers to tear off, doubling removal labor and disposal volume.
  • Extensive decking replacement discovered or anticipated.
  • Complex geometry - multiple valleys, dormers, skylights, chimney flashing work.
  • Three storeys or difficult access, affecting staging, delivery and dumpster placement.
  • A full manufacturer system installed to the specification an enhanced warranty requires.
  • Ventilation correction, which adds cost now and extends roof life later.

If several of these describe your roof, a figure that looked alarming against a published average may be entirely fair.

When A Low Number Should Worry You

The cheapest bid is sometimes simply a good contractor with efficient crews. More often it is a narrower job, and the difference surfaces later:

What was cutWhat it costs you later
Reused flashingA leak at a wall or chimney on a brand-new roof
No ventilation correctionShingles cooked from beneath; shortened roof life
Felt instead of synthetic underlaymentLess protection during and after install
No ice-and-water shield in valleysVulnerability at the roof's highest-risk areas
Decking unpricedAn open-ended change order mid-job
Permit excludedUnpermitted work surfacing at resale
Layover instead of tear-offShorter life; hidden decking problems left in place
No written workmanship warrantyNo recourse for installation failure

The Question Worth Asking Instead

Rather than "is this too much," ask: "what would make this number go down, and what would I be giving up?" A good contractor will answer honestly - a different shingle line, a smaller ventilation scope, phasing gutter work to later. A bad one will simply drop the price, which tells you the original figure was not tied to the work.

That second outcome is genuinely useful information. A price that falls under mild pressure was never a cost estimate.

Our Best Value Promise

Bring us any qualifying written estimate. We compare it line by line, and if we elect not to match or improve it, we refund your deposit and pay you $200. We publish that because it is the only honest way to make a price claim — it puts our money behind the comparison instead of asking you to take our word for it. Details on our Best Value Promise page.

The promise above is the practical answer to this whole page. You do not have to resolve whether a number is fair by argument - bring us the written estimate and we will compare it line by line against what we would do, with money behind the outcome.

Start With A Range

Our online ballpark tool gives you a defensible range for your address before you talk to anyone, which is the cheapest possible way to find out whether the figure in front of you is in the right neighbourhood. Then a free inspection and an itemized written estimate make it concrete.

Common Questions

Is $15,000 a reasonable price for a new roof?
It depends entirely on three facts nobody can guess: your roof's size in squares, its pitch and complexity, and what the quote includes. Fifteen thousand could be a strong price for a large steep cut-up roof with two layers coming off and decking replacement, and a poor one for a small single-storey gable with one layer and sound decking. Divide the quote by your own square count to get a price per square, then compare it against other written bids on the same roof with scope lined up.
How do I know if a roofing quote is fair?
Test it against your own roof rather than against a published average. Derive your square count, divide each written bid by it to get price per square, then compare the scope of each bid item by item - underlayment type, ice-and-water placement, new or reused flashing, ventilation work, pipe boots, decking per-sheet pricing, permit and warranty. The gap between a low bid and a high one is almost always explained by what the low one leaves out rather than by efficiency.
Why is my roofing quote higher than the average I found online?
Published averages blend roofs of every size, pitch, complexity and scope, so they cannot predict your specific job. Legitimate reasons your quote exceeds an average include a steep pitch requiring fall protection, two or more layers to tear off, extensive decking replacement, complex geometry with multiple valleys and dormers, three-storey or difficult access, a full manufacturer system installed to enhanced-warranty specification, and ventilation correction. If several describe your roof, the higher figure may be the accurate one.
Should I always choose the cheapest roofing quote?
No, and the cheapest bid deserves the most scrutiny rather than the least. It is occasionally a well-run contractor with efficient crews, but more often it represents a narrower scope - reused flashing, felt rather than synthetic underlayment, no ice-and-water shield in valleys, no ventilation correction, unpriced decking, an excluded permit, or a layover instead of a tear-off. Each of those saves money now and creates a specific, predictable cost later.
What should I do if a roofer drops the price when I hesitate?
Treat it as information about the company rather than as a win. A price tied to the actual cost of labor, materials, disposal and overhead does not fall simply because a homeowner paused - so a figure that drops under mild pressure was a negotiating position, not an estimate. A better question to ask any contractor is what would make the number go down and what you would be giving up, which a reputable company will answer honestly in terms of scope.
Can I negotiate a roof replacement price?
You can, but negotiate scope rather than demanding a lower number for identical work. Ask what a different shingle line would change, whether gutter work could be phased to later, or which items are genuinely optional versus load-bearing for the warranty. This produces a real reduction with a known trade-off.
