In the business of Roofing there are several expenses. Shingle disposal is one of them. Since disposal costs are determined by volume and weight, the question is HOW MUCH?
Let’s take a look at the differences in determining how much.
A couple of the measurement options would be square footage, shingle size, new shingle weight and every other item you could wrap your head around but the way we need to determine weight in a tear off is by Roofing Squares.
One square is equal to 100 square feet. For example, a 2,000 square foot roof is equal to 20 square.
Knowing approximately how many squares of shingles you have to dispose of makes it easier to communicate that info to the dumpster rental company, who can then recommend the right sized container.
Deciding whether a 10, 20, 30, or 40 yard dumpster is the right size for your re-roofing project depends on the type of shingle and how much of it you have.
For example, a 20 square roof with two layers of shingles will actually produce shingle waste equal to 40 squares.
Know how many layers of existing shingles are on your roof prior to ordering the dumpster to ensure you choose the right one and avoid having to get a second dumpster later.

Now that we have figured out how many squares of shingles we have, we need to know how much space they will take up in a dumpster and how much that will weigh. Shown in this photo are 3-tab shingles, let’s see the estimates on this style of shingle.
|# of Squares||Approximate Weight||Recommended Dumpster|
|10 Squares||1.5 Tons||15 Cubic Yard|
|20 Squares||3 Tons||15 or 20 Cubic Yard|
|30 Squares||4.5 Tons||20 or 30 Cubic Yard|
|40 Squares||6 Tons||30 Cubic Yard|
|50 Squares||7.5 Tons||30 or 40 Cubic Yard|
|60 Squares||9 tons||40 Cubic Yard|
Architectural-style roofing shingles are heavier and take up a bit more space compared to 3-tab shingles, so you’ll need a slightly larger dumpster to accommodate the extra bulk.
1820 sq ft/100= (18.2 squares) x 2 layers = 36.4 squares
Plan to round up. For a job of 40 squares of roofing shingles we will be in the ballpark of 6 tons and get a 30 Cubic Yard Dumpster.
Western Disposal Pricing shows that a 30 yard container in Albuquerque is $350 (2016.) This pricing includes 3.5 tons with additional tonnage being $30 per.
I will estimate the disposal costs on this project to be $350 (base) + $75 (additional tonnage) + $30.54 (tax) = $455.54.
