Roofing Tear-Off Dumpster Size Guide for Detroit Homes

Every spring the phone at the Meyers Road yard starts up with the same call. Somebody in Bagley or East English Village got a bid on a new roof, the roofer said order a dumpster, and they want a 30 yard because a roof sounds like a lot of stuff. Nine times out of ten that is the wrong can: a roof tear-off is a weight problem, not a volume problem.

Torn shingles do not fluff up the way framing lumber or cabinets do. They lie flat, they stack, and they pack down every time somebody tosses another shovel load on top. A tear-off hits legal axle weight while the container still looks two-thirds empty from the sidewalk. That is doubly true in Detroit, where the roofs are old, layered, and sometimes made of stone.

Squares and layers: the two numbers that decide everything

Roofers do not talk in square feet. They talk in squares, and a square is 100 square feet of roof surface. To rough it out, take the house footprint plus porch and attached garage, add 15 to 30 percent for pitch, and divide by 100. A Detroit bungalow with a simple gable runs 14 to 18 squares. A four-square in Grandmont-Rosedale is often 22 to 30. A big Palmer Woods house with dormers and a turret can pass 45.

The second number matters just as much: how many layers are coming off. For decades the cheap move on a tired roof was to shingle straight over the old one, and on century-old houses across this city two layers is normal and three is common. Every layer multiplies your weight. Two layers is not "a bit heavier." It is double. Get in the attic or have the roofer lift a shingle at a rake edge and count courses. Guessing wrong on layers is the number one reason a job needs an unplanned swap halfway through a Saturday.

What a square actually weighs

Here is the table we work from. These are approximations for a single layer torn off with felt and nails. Real loads vary with saturation, embedded ice and how much decking and old flashing comes along.

The pattern jumps out. Three-tab asphalt is the lightest thing on a Detroit roof. Architectural shingle, what almost everybody installs now, is meaningfully heavier per square than the three-tab it replaces. And slate and clay tile run several times the weight of a shingle square, which changes the whole conversation about size.

Slate and tile: the historic-district problem

People outside the city assume slate roofs are rare here. They are not. The bigger houses in Boston-Edison, Palmer Woods, Indian Village and Sherwood Forest genuinely have slate and clay tile, and plenty of surrounding stock has it on a turret or a dormer face even where the main planes are asphalt. When somebody on those streets says tear-off, we ask the material before anything else.

Slate is stone. A 20 square slate roof is serious tonnage that has nothing to do with cubic yards. On slate and tile we set a 10 yard roll-off or a small 15 yard container and plan on multiple pulls rather than one big can. A small box that leaves full and legal beats a big box unloaded by hand in the driveway.

Intact slate and unbroken clay tile have buyers, so pulling the good pieces before the container arrives is normal practice here. And all four neighborhoods sit under Historic District Commission review, so a material change can need approval first — confirm current requirements with the City of Detroit, because review processes change.

Multi-layer tear-offs and what is hiding underneath

On the oldest stock the bottom layer is often not asphalt at all. Cedar shake under asphalt shows up regularly on pre-1930 houses — wood shingles on spaced skip sheathing, covered over mid-century when the shakes gave out. Once you break into shake, volume goes up because shake does not compact like shingle, and the deck usually needs replacing. Budget an extra pull for plywood.

The felt layer is a stop-and-test moment

Roofing felt on pre-1980 houses can contain asbestos. So can some old roll roofing, flashing mastic and patching compound. Detroit's housing stock is overwhelmingly pre-1980, so this is not a remote possibility here, it is a live one on a large share of jobs.

If a crew tears into an unexpected layer — a black felted membrane nobody knew was there, a strange fibrous underlayment, a mastic that looks like nothing modern — that is a stop-and-test moment, not a keep-going moment. Stop, keep it wet or covered so it is not shedding, and get it sampled by a licensed inspector before another shovel goes in. Asbestos work in Michigan is regulated by EGLE with federal rules under the EPA, and requirements change, so confirm current rules with the agency.

We cannot take asbestos-containing material in any container, in any quantity. A contaminated load gets rejected at the scale and then it is sitting in your driveway. We would rather push a delivery a few days and let testing come back clean. Our guide to asbestos and lead paint in older Detroit homes is worth ten minutes first.

Why a weight-rated 15 or 20 beats a 30

A 30 yard roll-off is a wonderful thing for a bulky, light load: a garage full of furniture, a deck tear-out, insulation and siding. Fill one with three layers of wet shingle and it will not legally leave your driveway. The truck has to run Livernois or the Jeffries and cross a scale at a legal axle weight, and you will be standing there while the driver explains that half of it comes out by hand.

So for tear-offs we default to a 20 yard container or a 15, weight allowance matched to the material, and use next-day swap-outs instead of one oversized box. Two 20s that leave full and legal move more roof, faster, than one 30 that gets argued about in the street.

Detroit seasons drive the work

Winter and ice damming drive a huge share of the repair and replacement calls. Snow melts off a warm attic, refreezes at the cold eave, and water backs up under the shingles and finds the deck. By March you have stained ceilings in the back bedroom, and plenty of those turn into full tear-offs. Then spring: hail, and the straight-line wind that comes through Wayne County most years and strips tabs off whole blocks at a time. That is the busy stretch, and also when driveways are softest after the thaw. Winter delivery takes planning — ice on a sloped drive stops a delivery, plows throw windrows across a parked container, and a can left through a February freeze bonds to the ground.

Placement, protection and the things overhead

Put the container as close as you can to the side of the house the crew is tearing. Every extra step is time on the clock and more debris in the grass. Detroit driveways are old concrete with freeze-thaw damage already in them, so protection boards go under every can we set as standard — our page on protecting a driveway during delivery covers what we lay down.

Watch two structures. The porch roof on a bungalow or four-square is low, framed lighter than the main roof, and sits exactly where people want to throw debris — it is not a landing pad. The detached garage at the back of the lot is the classic casualty, backed into by a driver or hit by a bundle sailed off the north slope. Point both out before delivery.

Alleys, when there is no driveway

Plenty of houses on the older grid have no driveway at all, and for those the rear alley is the only realistic place to set a container. Detroit alleys vary wildly. Some are the fastest way in and we use them daily. Others are vacated, blocked by fly-dumping, or soft enough after a thaw that a loaded truck should not attempt it. That is why we ask your cross streets before committing to a time.

If there is no drive and no usable alley, the container goes in the street, which generally means a permit. Rules and lead times change, so confirm the current process with the city; we walk through it in our guide to dumpster permits in Detroit.

Low limbs and service drops

The old tree-lined streets on the west side and around Sherwood Forest are beautiful and they are a genuine obstacle. A roll-off truck needs real vertical clearance to raise the rails and roll a can off, well more than the height of the container itself, and mature silver maples over a driveway will stop a delivery. Worse are the overhead service drops — electric, cable and phone running from the pole to the corner of the house. On older properties those hang low and often cross exactly where a container needs to land. Walk your drive, look straight up, and tell us what is there.

Cleanup on a narrow lot

Detroit lots are narrow. On a standard 30 or 35 foot lot your neighbor's house is often four feet from your side wall, so half of what comes off your roof has a path into their yard. Tarp both sides before the first shingle comes off, and tarp their side too where the setback is tight. Cheaper than the conversation you will otherwise have over the fence.

Nails are the real hazard. A tear-off sheds thousands into the grass, the beds, the drive and the sidewalk. Run a rolling magnet over every hard surface and every foot of lawn the crew worked, once at the end of each day and again when the can leaves. Kids, dogs and tires all find what you miss.

Old gutters, flashing and aluminum trim are scrap, worth pulling separately. If the job takes down branches for access, Michigan bans yard clippings from landfill disposal, so brush goes out as a separate clean load, never mixed with shingle. Our rundown of what can and cannot go in a dumpster in Wayne County has the full list, and rules get updated, so check current guidance with Wayne County.

Ordering it right the first time

Call with three numbers and we will get the right can there first try: squares, layers and material. Add the year the house was built, because that tells us whether asbestos testing comes first. If you are sizing a bigger project, our Detroit dumpster sizing guide covers the rest of the house and our roofing dumpster rental service page has the tear-off specifics.

DTR Dumpster Rental Detroit has run roll-offs out of 14286 Meyers Road since 2014, and Andre and the crew have set cans on every kind of Detroit roof there is — three-tab bungalows in Brightmoor, three-layer tear-offs in Morningside, slate in Indian Village. Licensed and insured, locally owned, flat-rate, protection boards standard, next-day swap-outs so a big roof never stalls. Need one tomorrow? Ask about same-day and next-day delivery. Call (586) 600-7076 with your squares, layers and material and we will tell you exactly what to put in the driveway.
