Roofing Tear-Off Dumpster Size Guide for Columbia and the Midlands

Every other job we quote, the customer starts with square footage. Roofing is the one where that number will put you in the wrong box. A roof is not measured in square feet by the people who tear it off, and the container underneath it is not filled to the top — it is filled to the weight.

Dale Carver has been dropping roofing boxes around Richland and Lexington counties since 2014, and the conversation is the same every spring. Somebody has 28 squares, three layers and a 40 yard in their head because they want one trip. That box sits in the driveway loaded and unmovable, and nobody wins.

Squares and layers, not square footage

A square is 100 square feet of roof surface. It is the only unit roofers use, and it already accounts for pitch and overhang if the roofer measured properly — a 2,000 square foot ranch does not have 20 squares of roof, it usually has 24 to 28 once you allow for slope, eaves, hips and valleys. Get the square count from whoever is doing the work before you call anybody about a container.

The second number is layers — how many roofs are stacked up there right now. Two is common on Columbia houses re-roofed in the eighties or nineties without a tear-off, and three shows up more often than it should on the older stock.

Multiply and you have your weight. Rough working ranges we use when we size a box:

• Standard three-tab asphalt shingle: roughly 200–250 lbs per square.
• Architectural or dimensional shingle: roughly 350–450 lbs per square. This is most re-roofs done in the last twenty-odd years, and it is nearly double the weight of three-tab for the same roof area.
• Old wood shake: roughly 300–400 lbs per square, and bulkier than it weighs.
• Felt, nails, drip edge, ridge cap and the boot flashings: call it another 5 to 10 percent on top of whatever the shingle math says.

So 25 squares of single-layer architectural shingle is somewhere around four to five tons before you add felt and trash. Put a second layer of three-tab under it and you are past six. That is the whole story of roofing sizing, and it is why this job never behaves like the volume-driven work covered in our Columbia dumpster sizing guide.

What we actually find under Columbia roofs

Multi-layer tear-offs are routine on the older housing stock. Shandon, Rosewood, Elmwood Park and Waverly are full of 1900s to 1940s bungalows and foursquares that have been re-roofed two or three times without anybody stripping to the deck. Crews open a corner expecting one layer, find two, and the whole load calculation moves.

On the oldest houses you also hit wood shake under the asphalt, sometimes on skip sheathing with no solid deck, and thick old roofing felt that comes off in heavy saturated sheets. Both add weight and slow the job, which means the container sits longer.

Out east and south — toward Eastover, Hopkins, Gaston and Swansea — the picture flips. Barns, shops, outbuildings and plenty of houses carry metal roofing. Metal is light per square and it is worth something. Pull the panels, keep them out of the mixed load and scrap them rather than paying to bury them — same for copper flashing and aluminium trim coil. What is left is felt, fasteners and bad decking, a much smaller container than people expect. Our notes on recycling and disposal in Richland County cover keeping those streams separate.

The sizing table

Match your square count to your layer count. When you land between two rows, take the larger box or plan a swap — a container you can legally haul beats one you cannot. The 20 yard roll-off carries most residential tear-offs in this market.

Why nobody should order a 40 for a tear-off

The 40 yard is a bulk box. It exists for light, fluffy, high-volume material — commercial cleanouts, cardboard, insulation, framing offcuts, furniture. Shingles are the opposite of that. You will hit legal road weight with the box barely a third full, and then we cannot haul it. Every time somebody insists on a 40 for a roof, the day ends with a partial reload. Two 20 yard hauls cost nothing in time when the swap is booked ahead. That logic is spelled out further on our roofing dumpster rental page.

Storm season decides the calendar

The Midlands re-roof market runs on weather, not on shingle age. Spring severe thunderstorms bring hail across Richland and Lexington in cells that take out a few neighbourhoods at a time, and afterwards every roofer, adjuster and container in both counties is spoken for inside a week. Calling early beats calling right. If a storm went over your street, get on a schedule before you have a final scope — sizes can be adjusted, a slot on the truck cannot.

Hurricanes reach Columbia as inland wind and rain, not storm surge. Matthew in 2016 and Florence in 2018 both stripped shingles and dropped limbs well inland, a hundred miles from the coast. The October 2015 flood remains the other benchmark event here, and while that was a water event rather than a wind event, it taught everyone in the trade what a regional debris surge looks like. Watch the National Weather Service when something is coming, and see our guide to flood and storm damage cleanup in Columbia for the wider sequence.

Insurance sequencing: photograph before it leaves

If a claim is involved, the order matters and it is not negotiable.

1. Open the claim first. Before the tear-off starts, ideally before the roofer is scheduled.
2. Photograph everything. Wide shots of each slope, close-ups of hail bruising or lifted tabs, interior staining, and the decking once exposed.
3. Keep a damaged shingle sample. Set two or three aside in a bag. Once the container leaves, the evidence is gone.
4. Get the adjuster's documented inspection before anything hits the box.

South Carolina insurance rules and claim deadlines change and policies differ. Confirm your deadlines with your carrier and the state before you commit to a schedule — do not take a contractor's word, or ours, as final.

Pre-1980 roofing felt and asbestos

Roofing felt, mastic and some old built-up roof systems from before 1980 can contain asbestos. That is not a technicality on a 1930s Elmwood Park bungalow or a mid-century flat roof. Stop and test rather than tear off. If it tests positive, it goes to a licensed abatement contractor — we cannot take asbestos-containing material in any container, on any job.

Asbestos and demolition notification now sit with the SC Department of Environmental Services (SC DES) following the 2024 split of DHEC, with public health matters at SC DPH. Demolition generally triggers an inspection and notification. That transition is recent, so verify current thresholds directly with SC DES rather than anything second-hand, this page included.

Heat, and how long the box actually sits

Columbia is one of the hottest cities in the country in summer, and roofing is the trade that feels it first. From June through September crews start at first light and work the shaded slopes as the sun moves. Nobody is standing on a black roof at three in the afternoon — not safely, and not without cooking the shingle they are installing. A tear-off that runs one long day in October becomes two shortened mornings in July, and the container sits accordingly. Plan the rental window around the crew's real hours.

Placement, oaks and Fall Line driveways

Put the box as close to the tear-off side as the driveway allows. Shovel distance is the whole job — every extra ten feet is thousands of pounds carried further.

• Overhead clearance. The hoist arm needs 20-plus feet of vertical room to set down and to pick up. This is the number one problem in Columbia, because water oak and live oak limbs hang low over half the driveways in Shandon, Heathwood, Melrose Heights and Earlewood. Walk out and look up before you book.
• Protection boards go under the rails as standard, and on a loaded roofing box that matters more than usual.
• Clear of the drip line. Keep the box out from under the eave so debris does not bounce back into the shrubs and the crew has a clean throw.
• Two soils, two problems. Columbia sits on the Fall Line: a sandhill drive gives way under a loaded truck, a red clay drive ruts and holds water for days. Tell us which you have — see our notes on driveway protection during delivery.
• Narrow older streets near campus — Rosewood, Olympia, the Shandon grid — often have no room on the property at all. If the box goes in the street or right of way, see dumpster permits in Columbia and confirm current rules with the City of Columbia, since local permitting changes.

Finishing the job right

Three things separate a clean roofing job from a callback. Run a magnet sweep over the driveway, yard and street when the last bundle is up — roofing nails find tyres and bare feet for years otherwise. Book the swap ahead on any multi-layer or large job so the crew is never waiting on a truck. And never leave a roof open overnight in a Midlands summer: the afternoon thunderstorm pattern from June through August will find any slope that is down to the deck, and a water-damaged ceiling costs more than the re-roof.

Keep the load clean. Shingles, felt, decking, flashing and nails ride together; yard debris does not. South Carolina keeps limbs and brush out of landfill disposal, so pine and oak limbs from the same storm go as a separate clean load. Our page on what can go in a dumpster in Richland County has the full list, and rules change, so check with Richland County.

Talk it through before you book
