42333

Analysis

NAICS 42333 is the 2022 NAICS industry for roofing, siding, and insulation material merchant wholesalers, part of 4233 (Lumber and Other Construction Materials Merchant Wholesalers).

It has only one more detailed code, 423330, which covers exactly the same activities; the definition, index entries and statistics are on that page.

County Business Patterns counts 3,581 US establishments in this code in 2023, employing 50,236 people at an average annual payroll of $86,596 per employee (75th percentile of national industries). 25% of the establishments have fewer than five employees, which points to larger operations.

By establishments it ranks 4th of the 4 codes at this level within Lumber and Other Construction Materials Merchant Wholesalers, with 19.8% of them.

Between 2018 and 2023 the number of establishments grew 8% and employment rose 8%. The 2018 count used NAICS 2017, so part of a large move can come from codes being redefined rather than from businesses opening or closing.
