Roofing Shingle Tear-Off Weight Guide: Sizing 15-Yard vs 20-Yard Containers in Chattanooga

Roof replacement is one of the most common applications for roll-off dumpster rentals in Hamilton and Bradley Counties. Because asphalt roofing shingles are dense and heavy, calculating tonnage accurately is critical to selecting the proper bin size.

Understanding Roofing "Squares" In the roofing industry, one "square" equals 100 square feet of roof surface.

Weight Per Square by Shingle Type: - **Standard 3-Tab Shingles**: ~190 to 220 lbs per square (Single Layer). - **Architectural / Tactical Shingles**: ~250 to 320 lbs per square (Single Layer). - **Heavyweight / Designer Shingles**: ~350 to 450 lbs per square. - *Note*: If your roof has 2 layers (an old layer underneath), multiply your square count by 2!

Sizing Formula & Recommendations: - **Up to 20 Squares (Single Layer)**: A **15-Yard Dumpster** (3-ton weight limit) easily holds up to 20 squares of architectural shingles with leftover capacity for underlayment, felt, and old valley flashing. - **20 to 35 Squares (Single Layer) or 15–20 Squares (Double Layer)**: A **20-Yard Dumpster** (4-ton weight limit) is the premier workhorse for whole-home roof replacements throughout Chattanooga and Cleveland TN. - **Large Commercial or Multi-Family Roofs (40+ Squares)**: Multiple 20-yard bins scheduled on consecutive swap-outs prevent exceeding highway weight limits while keeping your roofing crew moving fast.
