Why Roofing Debris Gets Its Own Sizing Rules

Roofing debris does not behave like ordinary household junk, and that trips up more first-time re-roofers than almost anything else in the sizing conversation. A living room's worth of furniture and boxes is bulky but light. A tear-off pile is the opposite — it looks compact once it is broken down and stacked at the curb, but it is dense, and weight is what fills a roll-off's legal capacity long before the box looks full. Get the size wrong on a roofing job and you either pay for empty space you never needed, or the crew stops mid tear-off because the container has already hit its tonnage line with half the roof still on the ground. The right starting point is the roof itself, not a guess based on the size of the house.

Sizing by Squares and by Layers

Roofers measure roof area in "squares" — one square covers 100 square feet of roof surface. That number, combined with how many layers of old shingle are coming off, is the real basis for sizing a container, not the square footage of the home underneath it.

  • Single-layer asphalt shingle tear-off, small to mid-size roof (roughly up to 20-25 squares): a 10 or 15 yard container is usually enough. Asphalt shingle is relatively light per square, so this is typically a volume-limited job rather than a weight-limited one.
  • Larger asphalt roofs, or any roof with two layers of shingle being torn off at once: step up to a 20 yard. A double-layer tear-off roughly doubles the weight for the same roof area, and that math is what catches homeowners who size off the first, single-layer job they ever watched a crew do.
  • Steep-pitch roofs, heavier architectural or dimensional shingle, or large multi-layer jobs: plan around a 20 yard as the practical minimum, and call us before delivery if the roof is on the larger side — these jobs tend to be a weight problem before they are a volume problem.

These are starting points, not a substitute for a five-minute phone call. Tell us the approximate roof size in squares, how many layers are coming off, and the shingle type, and we will size and quote it as one flat number rather than have you guess and get it wrong in either direction.

Asphalt Shingle Is the Standard Here — and Weight Still Adds Up

The overwhelming majority of homes across Woodstock, Holly Springs and the unincorporated Cherokee County communities we serve — Towne Lake, Oak Grove, Sixes, Hickory Flat and the rest — are roofed in asphalt shingle rather than tile or slate, which keeps most re-roofs on the more predictable end of the weight scale compared to some other parts of the country. That said, "asphalt" is not one uniform weight. Standard three-tab shingle is lighter than the heavier architectural or dimensional shingle many homeowners are now choosing for its wind and impact rating, and a roof upgrading from three-tab to architectural on the new install will generate a heavier tear-off pile than the old roof's weight alone would suggest, if the original layer is also thicker than expected. Mention the shingle type — old and new — when you book, and we will size around the real weight rather than a generic asphalt assumption.

Timing the Tear-Off Around Cherokee County's Storm Season

A lot of re-roofing in this part of Georgia is not discretionary — it follows storm damage. Cherokee County sits squarely in the path of spring severe-thunderstorm and tornado-watch season, and hail is a common, real cause of roof damage across the county during those months, which is why insurance-driven roof replacements tend to cluster in the weeks and months after a bad storm system moves through. If your project is a storm claim, the crew is often working on a schedule set by the adjuster and the contractor, not by you — but it is still worth booking the dumpster a few days ahead so delivery lines up with the crew's actual start date rather than trailing behind it.

If your re-roof is discretionary and your schedule has flexibility, it is worth thinking about two windows: spring severe-thunderstorm season, when an open tear-off can get caught by a fast-moving storm cell, and late summer into fall, when Gulf hurricane remnants can reach inland Georgia — 2024's Hurricane Helene remnant is a recent, well-documented example that brought down trees and power lines across Cherokee County. Neither season rules out a re-roof, but an exposed deck during either one is a real risk to the house, not just an inconvenience. Talk to your roofer about tarping and weather contingencies regardless of when the job falls, and keep an eye on the forecast for the days your roof will actually be open.

Permits: Driveway Placement vs the Street

Where the container sits on your property matters as much as which size you order. A dumpster placed entirely on your own driveway or other private property typically does not require a permit anywhere in our service area. Placement in the street or another public right-of-way is different, and which office handles that approval depends on where the address sits: inside Woodstock itself, it runs through the City's own right-of-way and encroachment permit process; in Holly Springs, that city runs its own separate municipal permit process; and across the thirteen unincorporated Cherokee County communities we serve, it falls under Cherokee County Code Enforcement rather than any city hall. None of these approvals tend to happen same-day, so if your driveway cannot fit the container and truck clearance a re-roof needs, ask us early — we can tell you what a given size realistically requires and flag whether a street placement and permit are the likely path before the crew's start date arrives.

Before the Truck Arrives: A Short Checklist

  1. Measure or estimate the roof in squares, and note whether it is a single- or double-layer tear-off.
  2. Confirm the shingle type going on and coming off — architectural shingle tears off heavier than a standard three-tab roof of the same size.
  3. Pick a placement spot: driveway is usually simplest and permit-free; street placement needs approval through the applicable city or county office, requested in advance.
  4. Check overhead clearance and driveway width against the container size, especially around trees or carports.
  5. Book delivery a few days ahead of the crew's start date, with an eye on the week's storm forecast if the timing is flexible.
  6. Confirm the tonnage allowance included with your container and ask what happens if the tear-off runs heavier than expected.

Call us with the roof size, shingle type and layer count and we will turn that checklist into one flat price covering delivery, the rental period, pickup and a stated tonnage allowance — sized for the roof you actually have, not a generic guess.

Frequently asked questions

What size dumpster do I need for a roof tear-off?

It depends on squares (100 sq ft units), the number of layers coming off, and the shingle type. A single-layer asphalt tear-off on a smaller roof often fits a 10 or 15 yard; double-layer tear-offs or larger roofs generally need a 20 yard as a practical minimum. Tell us the roof size and shingle type and we will size it exactly.

Why does a double-layer tear-off need a bigger container than a single-layer roof the same size?

Roofing debris is dense, and a second layer of old shingle roughly doubles the weight coming off the same roof area. Weight, not the size of the pile, is usually what fills a container's tonnage allowance first on a roofing job.

Do I need a permit to put a dumpster on my driveway for a re-roof?

A container kept entirely on your own driveway or other private property typically does not require a permit anywhere in our service area. Placing it in the street instead runs through Woodstock's own process, Holly Springs' separate municipal process, or Cherokee County Code Enforcement for the unincorporated communities, depending on the address.

When is the riskiest time to have an open roof in Cherokee County?

Spring severe-thunderstorm and tornado-watch season is the main one, since hail and fast-moving storm cells are a common, documented risk here. Late summer into fall can also bring Gulf hurricane remnants inland, as Hurricane Helene did in 2024. Neither season rules out a re-roof, but it is worth watching the forecast for the days the deck will be exposed.

What happens if my tear-off runs heavier than the tonnage included?

We state a tonnage allowance up front as part of your flat price. If a load looks like it will run over, tell us before pickup — we would rather swap to the right-size container or talk through the numbers than surprise you after the truck weighs in.
