Madison County Roofing Tear-Off Guide: Sizing Dumpsters for Shingles

## Roofing Waste Calculations for North Alabama Contractors When severe storms or hail sweep across Madison and Limestone Counties, roofing crews operate on demanding schedules. Accurate dumpster sizing prevents costly tonnage overage fees. ### Weight Per Square (100 Sq Ft) - **3-Tab Shingles**: ~200 to 250 lbs per square. - **Architectural Shingles**: ~300 to 400 lbs per square. - **Double Layer Roofs**: Multiply total weight by two, adding 15% for nails and underlayment. ### Sizing Rules - **Up to 25 Squares (Single Layer)**: A **10-Yard or 15-Yard Dumpster** (2.0 - 2.5 ton allowance) is ideal. - **25 to 45 Squares (Architectural)**: A **20-Yard Dumpster** (3.5 ton allowance) handles the heavy load with room to spare.
