How Commercial Roofers Stop No-Bidding Jobs They Could Win
Disclosure: Sharp Pencil sells commercial roofing takeoffs, so we have a stake in this topic.
Most commercial roofers no-bid good jobs because nobody has the hours, not because the job is wrong for them. Screen each invitation for fit before anyone opens the plans. Take measuring and counting off the estimator's desk so hours go to pricing, scope and the questions that decide the job; judgment stays. On our takeoff time guide, measuring and counting are about 45 percent of a typical takeoff.
Why good roofing jobs get no-bid
The invitation list is longer than the estimating hours. The jobs that get dropped are often the ones that need the most reading: multiple roof areas, mixed systems, tapered insulation, a long spec. Those are also the ones where a careful bid stands out.
From our guide on how long a commercial roof takeoff takes: a typical commercial re-roof of 40k to 150k SF runs 4 to 8 hours of focused estimator time by hand, a multi-level roof with several systems and tapered runs 8 to 16 hours, and a school, hospital, or phased occupied building runs 12 to 24 hours. Those are hours of focused work, which is not the same as elapsed time.
Adding estimators is not getting easier. The U.S. Bureau of Labor Statistics lists about 226,400 cost estimator jobs in 2025, projects a 3 percent decline from 2025 to 2035, and about 17,600 openings a year, all from replacing workers who leave. Specialty trade contractors employ 33 percent of cost estimators. BLS also notes that software is improving the productivity of these workers, requiring fewer estimators to do the same amount of work. That is BLS's outlook, not a claim that your market has a shortage.
Decide bid or no-bid before anyone measures
Make the call before takeoff starts. Once the hours are spent, the cost is the same whether you win or lose. A short screen is enough.
| Question | Bid it when | Pass or ask first when |
|---|---|---|
| Is it our system and our kind of building? | Low slope or steep slope we install; building type we know | A system or building type we do not install |
| Is it in our area? | Within where crews can run it | Outside where crews can run it |
| Is the set complete enough to price? | Roof plan, details, and spec section are there | Missing details or spec, and RFIs not allowed before bid (see the RFI register) |
| Who is asking and how many are bidding? | A GC or owner we can work with; a short list | A long bidder list with no relationship, or a bid window far shorter than the job's size suggests |
| Can we staff it if we win? | Crew calendar has room in the install window | Crew calendar is full in the install window |
| Do we have the hours to read it properly? | Someone can give the set a real look | If this is the only "no," that is the job this page is about |
Run that screen before anyone starts measuring. The goal is to spend takeoff hours on jobs you already decided to pursue.
Where the hours go on a commercial roofing bid
About 45 percent is measuring and counting; the rest is reading, details and pricing, where judgment matters.
Our takeoff time guide breaks a typical eight-hour commercial takeoff this way:
| Activity | Share of the time |
|---|---|
| Reading the specs and orienting to the set | 15 percent |
| Field area and perimeter measurement | 20 percent |
| Counting and cross-checking penetrations, drains and equipment | 25 percent |
| Details, edges, transitions and flashings | 20 percent |
| Pricing, labor build-up and markup | 15 percent |
| Writing the proposal and questions | 5 percent |
Counting is the largest share in the guide's table, at 25 percent. Measuring field areas and perimeters plus that counting together are about 45 percent. The other 55 percent is judgment.
Needs your estimator's judgment
- Reading the specs and orienting to the set
- Details, edges, transitions and flashings
- Pricing, labor and markup
- Scope decisions, exclusions, alternates and unit prices
- Bid strategy and talking to the GC
Needs care but not your estimator
- Measuring field areas and perimeters
- Linear items
- Counting penetrations, drains and equipment
Some of the costliest lines never show up as a roof plan quantity. See items not on the roof plan.
Example: one estimator's week, before and after handing off takeoffs (made up, not a real shop)
This example is invented. Use your own job mix and check time.
Assumptions: 30 hours a week available for bids (the rest goes to meetings, the field and change orders). Every bid in the example is a typical commercial job at 8 hours by hand, using the live guide's eight-hour breakdown and its 45 percent mechanical / 55 percent judgment split.
| Case | Hours per bid | How the hours break down | Bids in a 30-hour week |
|---|---|---|---|
| Before (by hand) | 8 hours | Full takeoff in house | 30 / 8 = 3.75, so 3 complete bids |
| After (takeoff handed off) | 5.9 hours | Estimator keeps about 55 percent of 8 hours (4.4) for reading, details and pricing, plus a 1.5 hour check against the drawings and answers to questions (our assumption for this example) | 30 / 5.9 ≈ 5.08, so about 5 complete bids |
Capacity in this example moves from 3 bids a week to about 5. If the check is 2 hours instead (4.4 + 2 = 6.4), 30 divided by 6.4 is about 4.7, so about 4 to 5 bids. The working figure here uses the 1.5 hour check and about 5 bids. Getting to something like 11 bids a week would mean most of the judgment work left the desk too, which is not how the guide splits the job.
The real number depends on your jobs and how long your check takes. For the money side of hire versus outsource, see the per-bid cost math.
Three ways to add bid capacity
Hire an estimator. A hire adds a person who can price, sell and run bids, not only measure. BLS lists a May 2025 median wage of $80,330 for cost estimators at specialty trade contractors. For the full salary versus per-takeoff comparison, see hire or outsource, the per-bid math.
Takeoff software. Software speeds up measuring for the estimator who still does it. The measuring stays on your desk; the tool shortens it. See roofing takeoff software compared for the tool side.
Outsourced takeoffs. Outsourcing moves the measuring and counting off the desk entirely; the estimator keeps judgment (reading, details, pricing, scope). From any service, expect every quantity to be traceable to a sheet, and open items to come back as questions, not guesses. What that looks like when you send work to us is in the Why send block below.
What to keep in house no matter what
- The bid/no-bid call
- Reading the specs and orienting to the set
- Details and flashings
- Pricing and labor rates
- Scope decisions and exclusions
- Alternates and unit prices
- Answering the GC
- The final check of quantities against the drawings
Hand off the counting, not the judgment.

FAQ
How do roofing contractors decide whether to bid a job?
Run a short screen before anyone measures: system and building fit, geography, whether the set is complete enough to price, who is asking and how many are bidding, whether you can staff the install window, and whether you have the hours to read it properly. Make the call before takeoff starts.
How many hours does a commercial roofing takeoff take?
On our takeoff time guide, a typical commercial re-roof of 40k to 150k SF runs 4 to 8 hours of focused estimator time by hand, a multi-level roof with several systems and tapered runs 8 to 16 hours, and a school, hospital, or phased occupied building runs 12 to 24 hours. Those are hours of focused work, which is not the same as elapsed time.
What part of a roofing estimate can be outsourced?
Measuring field areas and perimeters, linear items, and counting penetrations, drains, and equipment. On our takeoff time guide, that measuring and counting is about 45 percent of a typical takeoff. Reading the specs, details, pricing, scope, and bid strategy stay with your estimator.
Should I hire an estimator or outsource takeoffs?
Hire when you need a person who can price, sell, and run bids end to end. Outsource takeoffs when measuring and counting are the bottleneck and your estimator's judgment is the scarce part. For the per-bid cost math, see our hire or outsource guide.
