The official count
For the total: the US Census Bureau counts 509 establishments with paid employees under NAICS 238160 (Roofing Contractors) in Michigan (2023 CBP). 67Leads lists 23 roofing contractors there. The two numbers are not the same thing. CBP counts business locations with paid employees, so one-person firms with no payroll are left out of it, while our count is the Google Maps listings we hold and have graded for this trade.

How this differs from the other counters
The local business counter gives the numbers for one trade and place; businesses by state ranks the states; the ZIP code counter counts by ZIP. This page answers the question as asked, in one sentence you can quote, then breaks the number down city by city and puts the official Census count beside it where one exists.
Our count and the official count
Our number is the businesses 67Leads holds: map listings graded as the trade, with a phone number, and not opted out. It covers the cities collected so far, so it can be lower than the true total. The official total for most industries is the Census Bureau's County Business Patterns, which counts establishments with paid employees and so leaves out one-person firms. Neither is "every business"; quote the one that fits your question, with its source.
Questions
Type the question above. The answer is the live count in the 67Leads database with a breakdown by city, and the Census figure where the trade has a clean industry code.
No. It is the number of businesses in the 67Leads database. The official count of establishments with employees is the Census County Business Patterns, linked on every answer.
The two numbers are not the same thing. CBP counts business locations with paid employees, so one-person firms with no payroll are left out of it, while our count is the Google Maps listings we hold and have graded for this trade.
You can, and the answer will say so and count the trades we do carry in that place instead.
