About Class Code 5551: Scope, Inclusions, and Common Misclassifications
NCCI Class Code 5551 — officially "Roofing — All Kinds & Drivers" — is the workers' compensation classification for roofing contractors. It applies to roofing of every type, whether the roof is flat, sloped, or built-up, and covers new roof installation as well as repair and replacement work. The classification includes the drivers who transport crews and materials, and the NCCI scope also picks up the pressure washing of roofs. It is one of the highest-rated common construction codes because of severe fall exposure: workers operate at height, on pitched and slippery surfaces, and around roof edges and openings.
5551 is an "all employees" roofing code — the laborers, skilled roofers, and drivers who make up a roofing crew are generally reported together under this single classification rather than split by job title, which is why the site labels it "Roofing — All Employees." Because of the fall hazard it sits in a high hazard group and typically carries a base rate several times higher than light-construction trades and an order of magnitude above clerical codes. This page compares filed base-rate estimates for 5551 across states so a roofing contractor can see the spread before requesting a quote, and explains where the classification boundary falls.
What's Included Under Class Code 5551
5551 contemplates all kinds of roofing work — built-up, flat, sloped, shingle, membrane, metal, and tile roofing — performed by a roofing contractor, including both new installation and the repair or replacement of existing roofs. Drivers transporting the crew and materials to the job site are included in the classification, which is why the title ends in "& Drivers," and the NCCI scope also brings in the pressure washing of roofs. The classification reflects the dominant exposure of the trade: working at height on roof surfaces.
As with all contractor codes, 5551 is assigned from the operations actually performed during the policy year rather than from the contractor's license category, and it is the governing classification for a dedicated roofing operation. Because roofing is a high-severity exposure, carriers scrutinize fall-protection practices, and the experience modification factor on a roofing account can swing the premium dramatically — a clean loss history is one of the few levers a roofer has against the high base rate.
When Roofing Work Is NOT Coded 5551
The common boundary issues involve adjacent sheet-metal and structural work. Architectural and ornamental sheet-metal work, gutter and downspout installation done as a standalone sheet-metal operation, and the installation of skylights or HVAC equipment on a roof can fall under their own classifications rather than 5551, depending on the scope language and whether the work is a standalone operation or incidental to a roofing job. Spray or foam roofing and certain specialty membrane systems may also have classification nuances, so payroll should be tracked by operation when a contractor's work spans more than straight roofing.
Independent-bureau states are important for 5551. California (WCIRB), Pennsylvania (PCRB), Delaware (DCRB), New Jersey (NJCRIB), Michigan (CAOM), and North Carolina (NCRB) run their own rating bureaus and may use different roofing code numbers, phraseology, or separation rules than NCCI's 5551 — California in particular does not use the national 5551 number, so a California roofing contractor should check WCIRB's classification system rather than relying on the national comparison on this page.
