This calculator vs. a flat $950/square metal-roof special
"$950 a square" is not a price for a metal-roof install -- it is a price for one specific panel, pitch, and scope, quietly applied to every roof the truck pulls up to.
What a flat $950/square special is
A flat per-square special is the fastest way to quote: one coupon number, easy to advertise and easy for a homeowner to compare between roofers. It is the number a homeowner holding a competitor's flyer will call and ask a shop to match, whatever roof is actually up there.
The number behind it was set for one job -- a low-pitch overlay over existing shingles, one story, an easy exposed-fastener panel, and minimal trim -- and then reused for every roof afterward, whether or not the next job looks anything like the ranch overlay it was priced on.
What this calculator is
This page keeps no account and sends nothing to a server. You enter the plan dimensions and pitch, the panel type -- exposed fastener, snap-lock, or mechanical-lock standing seam -- overlay or full tear-off, stories, trim lineal feet by run, snow guards, pipe boots, and ice-and-water, plus your loaded labor and overhead. It prices the panel, the tear-off, the stories, and every trim run separately, and returns a walk-away price below which the job loses money -- for this roof, not a generic one.
| What a flat $950/square special does | What this calculator does instead |
|---|---|
| Charges the same per-square number whether the job is a 5V overlay on a 4/12 ranch or a mechanical-lock standing-seam tear-off on a 10/12 two-story with valleys and snow guards. | Prices the panel, pitch, and scope from what was entered, so the two jobs above come out at different numbers instead of one. |
| Has no line for a tear-off, so stripping a roof to deck gets quoted the same as a job that only ever needed an overlay. | Adds tear-off hours and a dumpster fee per square only when a full tear-off is entered, so the strip shows up instead of being absorbed. |
| Has no line for a portable seamer, so a mechanical-lock standing seam gets quoted the same as an easy exposed-fastener panel. | Adds seamer hours and a seamer fee only for a mechanical-lock panel, so the lock-forming machine costs more than a screw gun. |
| Assumes one story and minimal trim, so a two-story roof or a run of ridge, hip, valley, rake, and eave gets quoted the same as a simple ranch. | Prices extra story hours and every trim run by its own lineal feet, so a roof with hips and valleys costs more than one without. |
| Gives the crew a coupon price to quote, not a number to check a quote against when a homeowner asks to match a cheaper overlay special on a tear-off job. | Reports the walk-away price and the dollar gap against the flat special, so a shopped price can be scored against real cost before the crew commits to it. |
Three roofs, the same per-square special
Using this calculator's own shipped presets, at its own shipped shop rates ($36/hr crew wage, 32% payroll burden, 15% overhead on direct cost, a 25% target margin, $160 travel and equipment):
| Job | This calculator's break-even cost | The flat $950/square special | Verdict |
|---|---|---|---|
| 12.65 squares, 5V overlay, 4/12 ranch, one story -- the job the $950/square special is built on | $8,322.86 | $12,015.60 | Covers, +$3,692.74 |
| 18.46 squares, 5V tear-off, 8/12 Cape, two stories | $14,471.00 | $17,539.58 | Loses $3,068.59 below break-even once a tear-off and a second story enter |
| 26.04 squares, mechanical-lock standing seam tear-off, 10/12 two-story, valleys, snow guards | $35,050.90 | $24,738.00 | Loses $10,312.90 below break-even |
The flat special is $950 times the roof's own squares, not derived from any of the three jobs' scope. It covers the ranch overlay it was written for with room to spare, then falls further behind as tear-off, stories, and a mechanical-lock panel stack up -- exactly the jobs a flat per-square rate cannot see. Run your own roof's numbers in the calculator to see where it falls.
A flat special is not wrong because it is simple -- it is wrong when it is applied outside the one roof it was built for, and nothing about a per-square coupon tells you when that has happened. This calculator does not replace judgment about your market; it replaces the arithmetic a flat special skips.
Common questions
Why does a flat $950/square metal-roof special get a bid wrong?
Because the cost driver is panel type, tear-off, stories, and trim, not "roof squares" alone. A 12-square 5V-crimp overlay on a 4/12 ranch is a different job from a 26-square mechanical-lock standing-seam tear-off on a 10/12 two-story with valleys and snow guards -- and a flat per-square number cannot see which one it is looking at.
What does a flat per-square special usually leave out entirely?
The tear-off, the seamer time for a mechanical-lock standing seam, the story premium, the trim lineal feet, ice-and-water, and snow guards. A published per-square special is priced on the overlay -- panel over existing shingles, no tear-off, one story, minimal trim -- and has nowhere to put the hours for stripping a roof to deck, running a portable seamer, working a steep two-story, or every foot of ridge, hip, valley, rake, and eave.
How big is the pricing gap in practice?
On this calculator's own shipped presets, at its own shipped shop rates ($36/hr crew wage, 32% burden, 15% overhead, a 25% target margin, $160 travel and equipment): a 12.65-square 5V overlay on a 4/12 ranch -- the job the $950/square special is built on -- breaks even at $8,322.86 against the special's $12,015.60, so the special actually covers this job with $3,692.74 to spare. An 18.46-square 5V tear-off on an 8/12 two-story Cape breaks even at $14,471.00 against the special's $17,539.58 -- still short by $3,068.59 once a tear-off and a second story enter the bid. A 26.04-square mechanical-lock standing-seam tear-off on a 10/12 two-story with valleys and snow guards breaks even at $35,050.90 against the special's $24,738.00, over $10,300 below break-even.
Is a flat per-square special ever the right way to quote a metal roof?
For the one job it was actually priced on -- a low-pitch overlay, one story, an easy panel, minimal trim -- a flat rate can land close, and on this calculator's own numbers it does, with room to spare. The risk is applying it to a tear-off, a steeper pitch, extra stories, or a mechanical-lock standing seam without noticing, because the coupon does not know which roof it is looking at and neither does the crew until the tear-off starts.
Does this calculator know what to charge in my market?
No. It has no data on local labor or material rates. It takes the plan dimensions, pitch, panel type, tear-off, stories, trim lineal feet, snow guards, ice-and-water, and your loaded labor and overhead, and turns them into a walk-away price for the roof you describe -- the arithmetic a flat special skips, not a market survey.
