Hire a Commercial Roofing Estimator or Outsource the Takeoffs? The Per-Bid Math

By The Sharp Pencil team

Hiring a commercial roofing estimator at the BLS median wage for specialty trade contractors costs about $107,700 a year once benefits are added, or about $8,970 a month. At the sustainable pace our takeoff-time guide uses, about fifteen takeoffs a month, that is roughly $598 of salary and benefits per takeoff. Outsourced takeoffs publish at roughly $200 to $400 per plan set, so outsourcing usually wins on takeoffs alone. Hiring wins when you need a second person to price, sell, and run bids, not only to measure.

Why send your takeoffs to Sharp Pencil

The expensive part of a takeoff backlog is the jobs you no-bid because nobody has the hours. Each point below answers a specific way a takeoff costs you time or trust.

• Within 48 hours, usually within one business day. A takeoff that sits in a week-long queue is no help when the bid is due sooner.
• Every quantity names its sheet. Each quantity carries the sheet it came from and a confidence grade, so you are never stuck with a number you cannot check.
• Measurements marked up on your own sheets. Your job page shows the measurements drawn on your own sheets, and you can open and zoom them to check the numbers.
• No silent blanks. Any checklist line the drawings could not settle carries a written reason, not a blank or a guess.
• Questions instead of guesses. Anything the set leaves open comes back as a drafted RFI you can copy and send to your architect. Paste the answers into your job page and the takeoff is updated; one re-run is included when you answer the questions.
• Priced with your numbers. Send us your costs once in a simple price book, and each takeoff also comes back with a client-ready proposal and a re-price sheet, and the workbook adds a Pricing tab.
• UNPRICED instead of a guessed number. Where a cost is missing, the line says UNPRICED and shows the quantity, so nothing is hidden inside the total.
• A roofing professional reviews every paid job before it goes out. The review comes with every paid takeoff, not as an upgrade.
• Answers in one thread, not an email chain. Ask about your job in a thread on your job page. If a question needs a roofing estimator on our team, the answer comes back in the same thread.
• Your plans stay yours. They are used only for your takeoff, never shared or pooled, and deleted automatically after 90 days.
• First takeoff free on a live bid, then $395 per set. Try it on a job you are actually bidding before you pay anything.

Hire or outsource at a glance

The two choices buy different things. A hire buys a person. Outsourcing buys finished takeoffs. Many shops end up doing both.

What a commercial roofing estimator costs to hire

Start with the salary, then add what an employer pays on top of it. Every figure below has its source in the table further down.

Salary

The Bureau of Labor Statistics reports a median annual wage of $78,740 for cost estimators in May 2025, or $37.86 an hour. The lowest 10 percent earned less than $48,530 and the highest 10 percent more than $130,820. Specialty trade contractors, the industry group that includes roofing contractors, employ about a third of cost estimators, and the median there was $80,330.

BLS does not publish a separate line for commercial roofing estimators, and local markets vary widely, so use a salary you have actually been quoted if you have one.

Benefits and payroll costs

A salary is not the full cost of an employee. In the BLS Employer Costs for Employee Compensation survey for June 2026, wages and salaries made up 69.5 percent of employer compensation costs in the private construction industry, and benefits the other 30.5 percent. Paid leave, 5.1 percent, is already paid out of a salary, so the benefits on top of a salary come to 25.4 percent of total cost. Put another way, salary and paid leave are 74.6 percent of the total, which works out to about 34 cents of benefits for every dollar of salary.

Applied to the specialty trade median: $80,330 divided by 0.746 is about $107,700 a year, or about $8,970 a month.

Software, recruiting, and ramp-up

A new estimator needs a takeoff and markup license. Published software prices run about $260 to $3,600 per user per year, or roughly $22 to $300 a month; our page on what a commercial roofing takeoff costs lists them vendor by vendor. Recruiting takes your time, and BLS lists moderate-term on-the-job training for cost estimators, which it defines as more than 1 month and up to 12 months to reach competency. During that ramp-up you pay the full salary for less than full output.

How many takeoffs does a hire actually add?

An estimator's day is not all takeoffs. Our guide on how long a commercial roof takeoff really takes works through it: of an eight-hour day, realistically about four hours are bid production, and the rest goes to phone calls, submittals, and meetings. At six hours per takeoff, that is roughly three or four bids a week, or about fifteen a month at a sustainable pace.

The same guide puts a typical commercial job done by hand at four to twelve hours of focused estimator time, from 2 to 4 hours for a simple warehouse recover up to 12 to 24 hours for a school, hospital, or phased occupied building. If your jobs run long, a hire adds fewer takeoffs than fifteen a month; if they run short, more. Use your own average.

The per-bid math: a worked example

This example uses the BLS figures above and the fifteen-a-month pace, our guide's working figure. It counts salary and benefits only, before software, recruiting, or a desk.

Two readings of the same table, and both are true:

• Per takeoff, outsourcing is cheaper at fifteen a month. About $598 per takeoff for the hire, against $395 per set pay as you go, or $250 to $299 per takeoff on a monthly plan.
• Per hour, your own estimator is cheaper when they have spare hours. A six-hour takeoff is about $311 of loaded estimator time at the BLS figure (6 x $51.77). If your current estimator has open time, doing the takeoff in-house costs less than $395.

So the question is not the hourly rate. It is whether you have the hours. By these figures, a loaded estimator day is about $414 (8 x $51.77), which is a little below Sharp Pencil's own estimate that an estimator's day runs $450 to $650.

What outsourcing costs per takeoff

Published prices for outsourced commercial takeoffs run roughly $200 to $400 per plan set; the full sourced comparison is on our page on what a commercial roofing takeoff costs. Sharp Pencil's published prices:

Unused plan takeoffs end with the month and do not roll over, and plans run month to month with no cancellation fee. If you send more than 10 a month, email [email protected] and we will quote your volume. See Sharp Pencil's full pricing and terms.

Break-even: how many takeoffs a month before a hire pays for itself?

Divide the hire's monthly cost by the price of an outsourced takeoff. At the BLS figure, about $8,970 a month equals about 23 takeoffs at $395. On the Shop plan at its published rates ($2,500 for 10, then $275 a job), the same $8,970 covers about 33 takeoffs a month. If you regularly send more than 10 a month, we quote your volume instead.

A new hire adds about fifteen a month, our guide's working figure, fewer than the 23 that would match their cost at $395 (33 on Shop), so on takeoffs alone outsourcing costs less at any volume one new hire can cover. The math only turns if your jobs are short enough that one estimator turns out more than about 23 a month. Fifteen takeoffs on Shop cost $3,875 a month ($2,500 plus 5 x $275), or about $258 each.

That is only half the comparison, because a hire does more than takeoffs. The other half of their day, the calls, submittals, and meetings, is work your shop may need done too. If it does, count it.

When hiring is the better choice

Be honest with yourself about what the bottleneck is. Hiring is the better choice when:

• You need more than takeoffs. Pricing judgment, customer relationships, site visits, pre-bid meetings, and follow-up after bid day all need a person on your payroll. A takeoff service does not replace that work.
• Your jobs are short and steady. If your takeoffs are short enough that one estimator turns out more than about 23 a month (about 33 against Shop pricing), month after month, a salary costs less per takeoff than outsourcing. At our guide's working figure of about fifteen a month, it does not.
• You are building a bench. A hire learns your crews, your suppliers, and your customers, and that knowledge stays in the company.
• Much of your work is outside our scope. Sharp Pencil covers US commercial low-slope roofing (TPO, EPDM, new construction, re-roof, repairs), with standing seam and shingle supported. Residential is out of scope, and our addendum pricing is not settled yet. If your mix leans on work we do not cover, an in-house estimator covers it.

When outsourcing fits better

Outsourcing is the better choice when:

• Takeoff hours are the bottleneck. Your estimator knows how to price and sell, but measuring and counting eat the week, and invitations go unbid.
• Your volume swings. A per-takeoff price follows your bid calendar; a salary does not. Pay as you go has no minimum.
• You need help this month. Outsourcing helps on the next bid, without a recruiting search or months of ramp-up.

Where Sharp Pencil fits better: when the limit is estimating hours, not skill. The takeoff comes back within 48 hours, usually within one business day, with the source sheet and a confidence grade on every quantity, drafted RFIs for anything the set leaves open, and pricing from your own price book. A roofing professional reviews every paid job before it goes out.

The middle path: outsource the takeoff, keep your estimator on pricing

For many owners the answer is not either-or. Keep the estimator you have, send the takeoffs out, and move their hours to checking quantities, pricing with your costs, and writing the bid. Our guide on how long a commercial roof takeoff really takes makes the case that measuring and counting are the mechanical part of the work, and that the judgment should stay with your estimator.

This is also a low-risk way to test the math before you decide on a hire. Send out a month of takeoffs, count how many more bids you submitted, and compare the cost with the hire figures above. For what an outsourced takeoff should include, see our page on commercial roofing takeoff services.

Hidden costs on both sides

Neither option is only its headline price.

• For a hire: recruiting time, the ramp-up period before full output, software seats, and turnover. If a new estimator leaves, you start the search again.
• For outsourcing: your estimator still has to check the takeoff and price it. Ask what a second pass costs; at Sharp Pencil, one re-run is included when you answer our questions, and a further run is $50 in two cases only. Ask how addenda are charged, and ask what happens to your plans. Ours are deleted 90 days after upload, and we do not bid roofing work; see what happens to your plans and pricing.
• For both: items off the roof plan are where takeoffs miss things. Whoever does the takeoff, keep a list of open questions; see what belongs in a roofing RFI register.

How to run the numbers for your own shop

1. Take the salary you would actually pay and divide it by 0.746 to add benefits. Divide by 12 for a monthly cost.
2. Estimate how many takeoffs a new hire would add a month at a sustainable pace. Our guide's working figure is about fifteen.
3. Divide the monthly cost by that number to get a per-takeoff cost for the hire.
4. Compare it with an outsourced price per takeoff at your monthly volume.
5. Count last month's invitations and the bids you actually submitted. The gap is the work neither option is doing today.
6. Decide what else you need. If it is pricing, selling, and running bids, weigh that on the hire side.

FAQ

How much does it cost to hire a commercial roofing estimator?

BLS reports a May 2025 median wage of $80,330 for cost estimators at specialty trade contractors, the group that includes roofing contractors. Adding benefits at the construction industry share BLS reports for June 2026 brings that to about $107,700 a year, or about $8,970 a month, before software and recruiting.

How many takeoffs a month does it take to justify hiring an estimator?

At the BLS figure, one month of salary and benefits equals about 23 takeoffs at $395, or about 33 on a $2,500 monthly plan with $275 per job past 10. A new hire adds about fifteen a month, fewer than the 23 that would match their cost at $395, so on takeoffs alone outsourcing costs less at any volume one new hire can cover. The math only turns if your jobs are short enough that one estimator turns out more than about 23 a month.

Is it cheaper to outsource roofing takeoffs than to do them in-house?

Per takeoff, usually yes when you would need a new hire to do them: about $598 per takeoff at fifteen a month against $250 to $395 per takeoff on Sharp Pencil's published prices. Per hour, no: a six-hour takeoff is about $311 of loaded time for an estimator you already employ, so if your estimator has spare hours, in-house costs less.

When is hiring an estimator the better choice?

Hire when you need more than takeoffs, such as pricing judgment, customer relationships, and site visits, or when your jobs are short enough that one estimator turns out more than about 23 takeoffs a month. Hiring is also the answer for work Sharp Pencil does not cover, such as residential roofing.

Can I outsource takeoffs and keep my estimator?

Yes, and for many shops that is the best of both: the takeoff is outsourced, and your estimator spends the saved hours checking quantities, pricing with your costs, and writing the bid.

What do I get from an outsourced takeoff?

At Sharp Pencil you get the takeoff workbook with a Questions tab, a material order list when the takeoff supports one, and a client-ready proposal when you send us your costs. It comes back within 48 hours, usually within one business day, and a roofing professional reviews every paid job.

How long does it take to train a new estimator?

BLS lists moderate-term on-the-job training for cost estimators, which it defines as more than 1 month and up to 12 months of combined on-the-job experience and informal training to reach competency.
