Roofing shingles are deceptively heavy. When planning a roof replacement in Northwest Ohio, calculating shingle weight correctly is essential to avoid overweight fees.
Calculating Roofing Squares and Weight
One roofing square equals 100 square feet of roof surface. Standard 3-tab asphalt shingles weigh approximately 200–250 lbs per square, while architectural / dimensional shingles weigh 300–400 lbs per square.
If you are tearing off 2 layers of shingles on a 30-square roof, you are disposing of 60 total squares of material—which can easily exceed 6 to 9 tons!
Recommended Containers for Roofers
For most residential roofs up to 30 squares, a 20-yard dumpster provides the ideal balance of volume and weight capacity. For larger roofs, dual 20-yard containers are preferred over a single large bin to prevent exceeding road-legal weight limits.
