Plumbing, Electrical & Roofing Supply House Runs: The $45-$70/Hr Contractor Gig

If you have spent any time on DoorDash or Uber Eats, you already know the math problem: a $9 payout, eight miles of driving, and a customer who rates you four stars because the fries were lukewarm. Now picture the same eight miles with a $65 flat rate, one pickup, one drop, and no customer rating at all. That is a supply house run.

The work is simple to describe and almost nobody in the gig economy talks about it. You walk into a wholesale trade counter — Ferguson, Winsupply, Graybar, Platt, Rexel, ABC Supply, Beacon, SRS Distribution — pick up a will-call order that a contractor already paid for, load it into a cargo van or onto a roof rack, and drive it to a job site. No ice packs. No drink carriers. No waiting 12 minutes at a restaurant while three other drivers stare at the same order screen.

What makes it worth reading about in 2026 is the pay structure. Contractor supply runs are priced on the value of the delivery to the contractor, not on a food-delivery algorithm that assumes you are interchangeable with every other driver in the zone. A crew standing idle because a $400 water heater did not arrive is an expensive problem, and contractors pay to make that problem go away.

What a Supply House Run Actually Is

There are three ways this work shows up, and they pay differently.

Direct account work is the best version. You contract with a plumbing, electrical, or roofing company to handle their daily counter pickups. They text or email a list the night before, you show up when the doors open, and you run the parts to wherever the crew is working. You get paid a flat per-run rate or an hourly rate, invoiced weekly or biweekly. No platform, no 20% cut, no acceptance rate.

Platform work is the entry point. GoShare, Roadie, Curri, and Veho all carry contractor and industrial supply loads in most major metros. Payouts run per delivery and are usually posted up front, which makes them easy to evaluate against your own cost per mile. The volume is inconsistent, but a single afternoon pickup-and-drop can pay more than a four-hour dinner shift.

Hybrid work is what most drivers end up doing after a month: two or three direct accounts as the base, platform runs to fill the gaps. That mix smooths out the slow weeks and keeps your vehicle earning instead of sitting in a parking lot waiting for a ping.

Inside the Will-Call Counter: The Workflow That Decides Your Day

Walk into a busy Ferguson branch at 6:45 AM on a Tuesday and you will see the entire business model in about ninety seconds. Plumbers in work boots, electricians in company polos, and drivers like you, all waiting for the same thing: an order that was placed yesterday and is staged somewhere in a warehouse the size of a grocery store.

The workflow is consistent at almost every branch, and learning it is the difference between a 15-minute stop and a 50-minute one.

• Have the PO number before you walk in. The counter does not search by your name, the customer’s name, or what the part looks like. They search by purchase order or will-call number. Get it in writing from the contractor and read it off your phone.
• Know the job name too. Many contractors run several jobs under one account, and branches stage orders by job name and truck. If you have both the PO and the job name, you get pointed to the right bay immediately.
• Check the piece count before you sign. Signing the will-call sheet is you accepting custody of the order. If the sheet says 14 pieces and you count 13, resolve it at the counter, not on the job site 40 minutes later.
• Ask about returns and credits up front. Contractors order extras on purpose — three extra couplings, a second carton of fittings — and expect the driver to carry the returns back on the next run. A driver who handles credits without being asked becomes the driver who keeps the account.

Two practical details save real time. First, most branches have a separate pro desk or contractor counter away from the retail showroom; use it. Second, the loading dock is usually not where will-call gets loaded — there is a specific bay and often a specific employee who handles driver pickups. Ask on your first visit, write down the name, and use it every time after that.

The Three Trades, Three Very Different Loads

Plumbing, electrical, and roofing all move through the same counter, but they behave nothing alike once the order is in your vehicle. Treating them the same is how drivers crack fixtures, bend conduit, and lose a $2,000 account in the first week.

Plumbing: Water Heaters, Cast Iron, and Fragile Fixtures

Plumbing loads are heavy and top-heavy. A 50-gallon residential water heater runs roughly 120 to 160 pounds empty and stands almost five feet tall. Two of them in a cargo van need to be strapped to the wall, not left to lean against each other. Cast iron no-hub pipe comes in 10-foot lengths and weighs more than you expect per foot, which matters for your rear axle as much as for your back.

The fragile category is where the money hides. A single-piece toilet, a designer lavatory faucet, a wall-hung sink — these arrive in retail cartons that are not designed for a van with no tie-downs. Keep a moving blanket and two ratchet straps in the vehicle at all times. A $300 fixture replacement comes straight out of your week, and a contractor who has to explain a cracked sink to a homeowner will simply stop calling you.

Electrical: Wire Spools, Conduit, and the 10-Foot Rule

Electrical loads are lighter but longer. Ten-foot sticks of EMT and rigid conduit will not fit in a standard cargo van without going diagonal, and they will not fit in most SUVs at all. If you plan to take electrical accounts, either get a van with at least 10 feet of usable cargo length or invest in a proper ladder rack — clamped conduit at highway speed is a liability, not a load.

Wire spools are the other half of the category. A 500-foot spool of THHN is heavy, rolls if it is not blocked, and can turn a hard stop into a missile. Lay spools flat, block them with a cargo bar, and never stack panels or transformers on top of them. Switchgear and 200-amp panels arrive crated and are genuinely heavy — check the weight before you accept the run, because a half-ton pickup is sometimes the right vehicle and a cargo van sometimes is not.

Roofing: Weight, Wind, and the 6 AM Drop

Roofing is the highest-paying and least forgiving vertical. Architectural shingle bundles weigh 70 to 90 pounds each, and a crew that is starting at 7 AM wants 30 bundles on site, not a driver making three trips. That is a payload conversation, not a delivery conversation: 30 bundles is over a ton, and it changes which vehicle you need.

Roofing also runs on the earliest schedule of the three. Supply yards like ABC Supply, Beacon, and SRS typically open at 6 or 6:30 AM, and crews want material before the heat builds. If you cannot be at the yard at open, do not take roofing accounts — being late is the one mistake that gets a driver removed from a roofer’s rotation immediately. Membrane rolls and underlayment are lighter but awkward, often 3 to 4 feet wide and over 100 pounds, so plan how they will sit before the yard loads you.

Vehicle Math: What Fits, What Doesn’t, and When to Rent a Box Truck

You do not need a box truck to start. You do need to be honest about payload.

• Cargo van (Transit Connect, ProMaster City, NV200): handles plumbing fittings, electrical devices, wire, tools, and most single-appliance runs. Skip water heater doubles and full shingle orders.
• Full-size van (ProMaster 2500, Transit 250, Sprinter): the sweet spot for this work. Ten-foot conduit fits, two water heaters fit, and 1,500 to 2,000 pounds of payload is realistic.
• Pickup with ladder rack and trailer: fine for roofing and long stock if you know how to secure a load properly. Open beds and rain do not mix well with paper-wrapped shingles.
• Box truck: rent by the day only when a single run pays enough to cover it. A 16-foot box rental plus fuel is real money, and the run has to clear $250 or more to make the math work.

Whatever you drive, three pieces of equipment pay for themselves in the first month: a cargo bar or load lock, four ratchet straps rated for the load, and a moving blanket. The box truck and cargo van guide for hotshot freight breaks down the vehicle tiers and what each one can realistically carry.

How the Money Works in 2026

This is where supply house work separates from food delivery, and it is worth understanding the three pricing models before you accept your first run.

Flat Per-Run Rates

The most common structure with direct accounts. A short local run — yard to job site, under 15 miles, one pickup and one drop — typically prices between $45 and $85 depending on the market and the load. Long runs, cross-metro, or multi-stop days price higher, often $120 to $200. The rate is set by the contractor’s cost of a delayed crew, not by your miles, which is why a 12-mile run with a $70 rate exists at all.

Hourly Contractor Contracts

Larger mechanical, electrical, and roofing companies often prefer to pay hourly because their day is unpredictable. Rates in 2026 generally land between $28 and $38 per hour for a driver with their own properly insured vehicle, plus mileage in some agreements. The advantage is that slow days still pay. The disadvantage is that you need to be disciplined about your own hours and fuel costs, because a five-hour day with 90 miles of driving is not the same as a five-hour day with 30.

Platform Work: GoShare, Roadie, Curri, Veho

Platform runs price per delivery and are posted before you accept, which makes them easy to screen. A same-day contractor supply run in a major metro commonly pays $35 to $90, and longer regional runs can reach $150 or more. The trade-off is availability: these loads appear unpredictably, and you are competing with other drivers for them. Use platforms to fill gaps and to build a track record, not as your only source of supply-house work.

A Real Tuesday: Sample Day Math

Here is what a mixed day looks like for a driver in a mid-size metro running a full-size van with two direct accounts.

• 6:15 AM — arrive at the plumbing supply house, load two water heaters and 14 pieces of fittings. Run to a residential job site, 11 miles: $70.
• 8:00 AM — second trip from the same branch to a different crew, 9 miles, mostly copper and PVC: $55.
• 9:30 AM — return two cartons of unused fittings for credit, then pick up an electrical will-call at Graybar, 14 miles to a commercial job: $75.
• 12:00 PM — platform run through GoShare, 22 miles, light fixtures to a retail buildout: $85.
• 2:00 PM — afternoon plumbing run back to the first crew, 10 miles: $60.

That is five runs, 66 loaded miles plus roughly 25 deadhead miles, and $345 before fuel. At about 14 MPG and $3.40 a gallon, fuel runs near $22. A day like that five days a week lands in the $1,500 to $1,700 range gross, which is why drivers who get two steady accounts stop going back to food delivery. The 2026 real earnings breakdown shows why the food-delivery equivalent of the same hours usually lands far lower.

Getting Direct Accounts: The 15-Minute Pitch That Works

You do not need a sales background. You need to walk into a plumbing, electrical, or roofing shop at 3 PM — after the morning rush, before the crew meeting — and ask for the person who handles the trucks.

The pitch is four sentences. You are a local driver with a cargo van and commercial insurance. You specialize in supply house pickups and job site drops. You can commit to being at the counter when they open, and you can handle returns and credits without being chased. You would like to take their overflow for two weeks at no obligation so they can see how it works.

Two things make that pitch land. First, you are offering to solve a specific problem — the foreman waiting on a part — not offering generic delivery. Second, you are asking for overflow, not their whole business, which is a low-risk yes for a shop owner who has been burned by unreliable drivers before.

Bring a one-page sheet with your vehicle, insurance limits, service area, and phone number. Leave it even if the answer is no. Supply house counters turn over drivers constantly, and the shop that says no in October often calls in January.

Insurance, Cargo Liability, and Damage Claims

Personal auto policies exclude commercial use, and every one of these accounts is commercial use. You need a commercial auto policy or a commercial rider that explicitly covers hauling goods for hire, and you need to understand what it does and does not cover before a fixture slides into a tailgate.

Cargo coverage is separate from liability, and this is the gap that ends careers. If you crack a $900 decorative sink, your liability policy may cover the damage you caused to someone else’s property, but it will not necessarily pay the contractor for the freight you were carrying. Ask specifically about cargo insurance limits, and be ready to show a certificate of insurance — most established contractors will not add you to their rotation without one.

Platform work usually includes limited cargo protection, but the limits are low and the claims process is slow. Direct account work puts the risk squarely on you, which is exactly why the rates are higher. Read the delivery driver insurance guide before you sign your first contract, and treat cargo coverage as a cost of doing business rather than an optional extra.

The Mistakes That Lose an Account in Week One

Accounts are not lost because a driver is slow. They are lost because of small failures that make the contractor look bad in front of their customer.

• Wrong PO number. You pick up the wrong job’s order, the crew waits, and the branch has to restage. Confirm the PO and the job name out loud at the counter.
• No signature at delivery. Leaving material at a job site without a name and a signature creates a dispute the moment something goes missing. Get a name, a time, and a photo.
• Damaged fixtures. No blanket, no straps, no padding. One cracked sink is enough.
• Missing load bars. Spools and pipe that shift in transit damage the vehicle and the load, and a load shift on the highway is a safety event, not an inconvenience.
• Missing the 6 AM window. Roofing and commercial crews plan their day around material arriving first. Late once is a warning; late twice is a replacement.
• No communication. A two-line text — “loaded, leaving branch, ETA 8:20” — is the single cheapest way to keep an account.

Building a Recurring Route

The real prize in this work is not the $70 run. It is the standing schedule: the same branch at the same time every morning, the same three crews, the same invoice every Friday. Once you have that, your income stops depending on an app’s algorithm and starts depending on relationships you control.

Start with one account and one branch. Learn the counter staff by name, learn the loading bay, and learn which days the yard is chaos. Add a second trade only after the first is running smoothly, and keep your vehicle maintained on a schedule rather than on breakdowns. The HVAC parts and equipment guide and the hardware and home improvement delivery guide cover the adjacent verticals, and the vehicle math is largely the same.

Track your miles from day one. Supply house work racks up deadhead miles between branches and job sites, and those miles are deductible. The 2026 IRS mileage rate guide explains how to claim them, and the fuel card and cashback comparison is worth fifteen minutes if you are running 300 miles a week.

None of this is glamorous. It is boxes, straps, early mornings, and a clipboard. But it pays like a trade instead of paying like a tip jar, and in a year when food delivery pay keeps compressing, that difference is the whole game. Walk into one supply house this week, ask for the counter manager, and find out what their drivers are getting paid. The worst outcome is a fifteen-minute conversation.
