What a roofing crew drives and what it carries are covered by two different lines, and neither one is general liability. Commercial auto answers the crew trucks and trailers on the road; contractors equipment — an inland marine line — answers the tools, machines, harnesses, and staged material the business owns. Knowing which line answers what is how you avoid an uncovered loss.
The short version: commercial auto covers the vehicles you put on the road and the borrowed or personal truck driven for the business, while contractors equipment follows your movable gear and material wherever the work takes it. Both are distinct from the roofing work itself, which runs through general liability. This post walks the road-and-jobsite split so you can see where each line starts and stops; those coverage pages own the full architecture, and this post is about how the two lines fit together on a working roofing operation.
What commercial auto covers: the crew trucks and trailers on the road
Commercial auto covers the vehicles your roofing business owns and runs for work — the pickups and flatbeds that carry crews and material, the trucks and dumps that move tear-off, and the trailers hauled behind them. It provides three things a roofing operation leans on: auto liability for the at-fault accident, physical damage for the trucks and trailers themselves, and the hired-and-non-owned piece covered below.
Which vehicles are actually covered, and for what, is set by the covered-auto symbols shown on your policy’s declarations. That is a detail worth reading before a loss rather than during one, because a truck that never made it onto the schedule is a truck the policy may not answer for. The trucks run between the shop and the jobsite every working day, hauling crews out in the morning and tear-off debris back in the afternoon, and the coverage only follows the vehicles the policy actually lists on that schedule.
Hired-and-non-owned auto: the borrowed or personal truck
The exposure that surprises owners most is the vehicle the business does not own but still relies on. If a crew member or a sub drives his own personal truck to pick up material or run a job errand and causes an accident, his personal auto policy may not respond to a business use — and the business can still be pulled into the claim. Hired-and-non-owned auto is built for exactly this gap.
In the standard Business Auto Coverage Form, known as CA 00 01, the two covered-auto symbols that matter here are symbol 8 for hired autos — a truck you rent, lease, hire, or borrow — and symbol 9 for non-owned autos, such as an employee’s personal truck used for the business. An owner who assumes a personal policy covers a work errand is carrying an uncovered exposure until this coverage is in place. Editions and exact forms vary by carrier, so confirm the symbols actually shown on your own declarations rather than assume the standard pair is there.
What contractors equipment covers: the tools, machines, and staged material
The gear is a separate line entirely. Contractors equipment is an inland marine line that covers the movable property your roofing business owns and uses to do the work: ladders and roof jacks, harnesses and the rest of your fall-protection gear, nail guns and compressors, generators, standing-seam and metal-forming machines, and hand and power tools. It responds to theft, vandalism, fire, and accidental physical damage to that property.
Inland marine is largely a non-standard, manuscript line — there is no single industry form number the way there is for auto — so the mechanics live in how your policy is written rather than in a common code. What matters is that this line follows the property, not the truck: the gear is covered on the jobsite, in transit between the shop and the roof, and in storage or the yard, wherever the work takes it.
On the jobsite and in transit: where the gear is exposed
The staged material deserves its own mention, because for a roofing contractor the material can represent as much value as the tools. Shingles, membrane rolls, metal coil and panels, tile, fasteners, and underlayment that you own and have staged for an upcoming install are real money sitting on a jobsite, in the yard, or on the truck before it ever goes up on the roof. The mechanism that covers material being moved to and installed on a project is sometimes called an installation floater, part of the same inland marine family as the equipment floater.
Whether your policy schedules that material, and while it sits at which locations, depends on how the line is written — which is exactly the kind of detail worth confirming before the material shows up on site, not after a theft.
Where these two lines stop and general liability begins
The seam is worth stating plainly, because all three lines meet on the same jobsite and owners routinely blur them. General liability answers the roofing work and the harm it causes to other people and their property — a passerby struck by a dropped tool, water damage to the building from a failed install. It does not cover the crew truck, and it does not cover your own tools and material. The truck is commercial auto. The gear is contractors equipment.
Put the other way around: contractors equipment covers your own movable property, not the harm your work does to others; commercial auto covers the vehicle, not the roofing operation or the gear riding in it. Each line has a clean job. The trouble starts only when an operation assumes one policy quietly reaches across all three.
Real-World Scenario: A crew loads a rented flatbed with a standing-seam machine and a pallet of metal panels and heads to a jobsite. On the way, the driver rear-ends another vehicle; overnight, thieves break into the same truck parked at the site and take the machine and the tools. Three different lines are in play. The auto liability for the accident runs through commercial auto, and because the flatbed was rented, the hired-auto side responds. The stolen machine and tools run through contractors equipment, the inland marine line that follows the gear rather than the truck. And if the driver had used his own personal pickup for the run instead, the non-owned side of the auto policy — not his personal policy — would be the one reaching the business’s liability. One trip, three coverages, none of them general liability.
Why owners assume the wrong policy answers
The confusion is natural, because the truck, the gear, and the work all show up on the same roof on the same day. It is easy to picture a single policy standing behind the whole operation. But the lines are drawn around different property and different risk: the vehicle, the movable equipment and material, and the work itself. A loss that lands in the wrong mental bucket is a loss the owner expects the wrong policy to pay.
The way through is to read the schedules. The commercial auto policy answers only for the vehicles listed and the symbols shown; the contractors equipment line answers only for the equipment and material actually scheduled, at the locations the wording reaches. Both are worth confirming against how the operation actually runs — how many trucks, whose trucks, which machines, how much material staged where — the same way any commercial and industrial roofing account gets read before a policy binds.
Line up both lines before the loss
The takeaway is simple: what a roofing crew drives runs through commercial auto — the trucks and trailers on the road, plus the borrowed or personal truck under hired-and-non-owned — and what a crew carries runs through contractors equipment, the inland marine line that follows the tools, machines, and staged material on the jobsite and in transit. Neither is general liability, which answers the roofing work and the harm it causes. Confirm the vehicles and symbols on the auto policy, confirm the equipment and material scheduled on the inland marine line, and read them against how your operation actually runs before a loss tests them. When you are ready, start a quote, read the commercial auto and contractors equipment pages for how each line is built, or browse the coverage overview to see where every line sits.
