How much does a bundle of shingles weigh?
A bundle of asphalt shingles weighs roughly 50 to 80 pounds. Standard three-tab bundles are on the lighter end (around 50 to 65 pounds); architectural and designer shingles are heavier, often 65 to 80-plus pounds per bundle.
Since three bundles typically make a square, a square of asphalt shingles weighs about 150 to 240 pounds. That weight matters for structural load and for how many bundles a crew stages on a roof at once.
If you are hauling or loading bundles yourself, treat each one as a heavy, awkward lift and check your vehicle's payload before loading a full roof's worth.
