Missed call revenue calculator
A missed call in roofing is not a lost call. It is a homeowner who dials the next contractor on the search results page while your voicemail is still playing. This calculator puts a number on that: enter your inbound volume, the share of calls that currently ring out, your close rate on the ones you do answer, and a typical job value, and it returns the revenue that leaves through the phone each month and each year.
Nothing is stored, nothing is emailed to you, and there is no form in front of it. The arithmetic is printed underneath the result so you can check it against your own spreadsheet.

What missed calls cost your roofing company
Every unanswered inbound call is a homeowner who calls the next roofer on the list. Adjust the numbers below to estimate the revenue slipping away each month and year.
Estimated revenue lost to missed calls
Per month

- Lost jobs per week

How this is calculated
Missed calls per week = inbound calls per week x percent missed. Multiply by your close rate to get the jobs you would have booked, then by average job value for weekly lost revenue. Monthly and yearly figures scale that weekly number.
lost_per_week = calls_per_week x (percent_missed / 100)
x (close_rate / 100) x avg_job_value
lost_per_month = lost_per_week x (52 / 12)
lost_per_year = lost_per_week x 52Note: figures are estimates based on the inputs you provide. They are illustrative and not a guarantee of results. Replace the defaults with your own numbers for a tailored estimate.
How to read the result
Four numbers come back. Missed calls per week and lost jobs per week are the honest ones, because they are small enough to sanity-check against what you already know about your week. The monthly and yearly revenue figures are those same two numbers multiplied out, so treat them as a scale indicator rather than a precise forecast -- a one-point error in your miss rate moves the annual figure by thousands.
The input that decides everything is the percent of calls missed, and it is the one almost every owner guesses low. Guessing is avoidable: your phone system or tracking number reports it directly. Pull a month of call detail, count the calls with no answer, no talk time, or a voicemail disposition, and divide by total inbound. Do it for evenings and weekends separately if you can. That split is usually where the number people quote from memory and the number in the log stop agreeing.
Two things the result deliberately does not do. It does not assume a missed call is gone forever -- some homeowners call back, and if you return the call quickly some of the rest are recoverable, so read the output as the exposure you are carrying rather than a confirmed loss. And it applies your answered-call close rate to the missed ones, which is generous to the estimate in one direction and harsh in the other: a caller who had to leave a message is a colder prospect by the time you reach them, but they were also motivated enough to pick up the phone in the first place.
Why the phone goes unanswered in a roofing shop
It is almost never indifference. Federal establishment data says most of this industry is very small, and in a crew that size the person who would answer is on a roof, on a ladder, or in front of a customer. The wage figures below are the other half of the same point: the hour a roofer spends fielding a call is the more expensive hour, and it is also the hour that was supposed to produce work.
Both wage figures are US medians published by the Bureau of Labor Statistics, and the establishment counts come from the Census Bureau's County Business Patterns. Note what the establishment number is and is not: it counts business locations with payroll, so a contractor with three yards is counted three times and sole operators with no employees are not counted at all. That makes it a floor on how many roofing businesses exist, and it makes the share of very small ones conservative rather than inflated.
What to do with the number
Compare it against what coverage would cost. If the annual figure is meaningfully larger than a year of answering coverage, the decision is arithmetic rather than judgement; if it is smaller, you have a lead-volume problem rather than a call-handling one, and the honest answer is to fix that first.
- Roofing answering service -- who picks up when your crew cannot, including evenings, weekends and the hours after a storm.
- Roofing call center services -- the full intake picture: inbound answering, outbound follow-up on the calls you already have, and appointment setting.
- Call center cost estimator -- price the other side of the comparison before you make it.
