Your Gravel Drive Has to Carry the Roof Truck, So Plan the Route

A lot of St. Charles County homes sit on gravel or crushed-stone drives, especially where the lot was graded before anyone poured concrete or where the drive runs back to a garage on acreage at the edge of town. A roof replacement puts a different load on that drive than an ordinary week of traffic does. The delivery truck carries shingle bundles, the dumpster or roll-off arrives full, and the crew's trucks come and go several times a day for a few days. Stone that held up under the family car can rut under that weight in a single afternoon.

Why gravel changes the truck plan

Gravel drives fail in predictable ways. Loose stone pushes outward under the tires of a heavy truck, leaving ruts at the wheel lines and a ridge in the middle. After a rain, the clay under the stone can go soft, so the stone sinks into it and the surface turns to washboard. Through a St. Charles winter, the freeze and thaw cycle lifts stone at the edges and heaves the drive, and early spring is the worst time to put a loaded truck on it. A drive that was fine in October can be unusable in the week the roof is scheduled.

The truck is the problem, not the crew. A shingle delivery is heavy and sits on the drive while the driver unloads. A roll-off dumpster full of tear-off debris is heavier still, and its wheels or skids press point loads into stone that was never built for them. The roofer should know the drive's condition before the truck is booked, and the homeowner should know which parts of the drive will carry it.

Three places a truck can stop

On most lots there are three candidate spots for the heavy vehicles: the public road or shoulder, the drive itself, and the yard or side lot beside the house. Each has a cost. A truck parked on the shoulder blocks a lane and may need a permit depending on the street and the work zone. A truck on the drive can rut it. A truck on the lawn kills the grass and can sink into soft ground after rain.

Ask the roofer to name which of the three the delivery will use, which the dumpster will use, and where the crew's own vehicles will park. Those are three separate answers. A bid that says the crew will work from the drive, without saying where the delivery truck waits, has left out the part that causes the damage.

Measure your own drive before anyone quotes it

Walk the drive with a tape and a phone. Note the width at the narrowest point, which is often the gate, the mailbox, or the gap beside a tree. Check the slope where the drive meets the road, because a truck that has to climb out of a low spot or back down a steep grade needs more room than the width suggests. Look for a culvert or ditch crossing near the road. A culvert that is not rated for a heavy truck can crack under the wheel, and the repair lands on the homeowner's side of the property line.

Walk it again after a rain if you can. A drive that is firm on a dry afternoon can be a different surface the next morning, and that difference is what the roofer needs to see before scheduling the delivery.

Where the dumpster sits on stone

A roll-off dumpster on loose gravel tends to sink on one side and tilt, which makes loading harder and can damage the container's rails. Many crews set boards or steel plates under the legs or rails for this reason. Ask whether those are included in the bid, and ask who is responsible for the stone the dumpster displaces when it is picked up. Lifting a full bin off soft stone can pull the surface up with it.

If the dumpster needs to sit on the drive, the question is whether it blocks the way the family uses the house. Ask where the driveway stays clear for a car to get out, and where the gate or side yard stays open. Those are small details, but on a gravel lot they decide whether the roof job is a few days of inconvenience or a standing problem.

What to ask each roofer

• What is the loaded weight of the delivery truck, and will it come onto the drive or stop at the road?
• Will the bundles be staged on the drive, on the lawn, or on a tarp near the house?
• Where does the dumpster sit, and what does the crew put under it?
• Who regrades and replaces stone that the trucks displace, and is that line in the bid?
• What happens to the schedule if the drive is soft from rain on delivery day?
• Where do the crew's own vehicles park, and do they stay off the lawn?

Look for these answers in the written scope, not only in a verbal promise. If a roofer says the drive will be fine but the bid says nothing about stone, then the stone is not included.

What it costs and where it shows up

Stone replacement, grading, plywood or steel mats under the dumpster, and extra hauling for ruts are all real costs. None of them has to be large, but they are easy to leave out of a bid and then appear as a line on the final bill. Ask whether each one is a priced line, an allowance, or excluded. An allowance is an estimate that the final bill may move, and an exclusion means the homeowner pays separately if the work turns out to be needed. Put the question in writing so both answers are on the same page.

When the drive says wait

A good roofer will move the delivery to a dry day, or to the road, when the drive cannot take the load. That decision should be a hold point in the schedule, written before the job starts, so nobody has to argue about it on the morning of the delivery. If the drive is soft, the usual answer is to wait a day, not to push a loaded truck across it and repair the ruts afterward.
