What Size Dumpster Do I Need for a Roofing Project?
By Dumpstar Hauling & Dumpster Rental of Lexington, KY | Dumpster Rental Tips
For most residential roof replacements in Lexington, KY, you need either a 14-yard dumpster (starting at $400) for smaller repairs under 10–12 squares with a single layer, or a 20-yard dumpster (starting at $495) for standard full replacements of 15–25 squares. Roofing shingles weigh 200–430 lbs per square depending on type — weight hits the limit before the container looks full. The two factors that decide your size: how many squares you're removing and how many layers are coming off. Our free Dumpster Size Calculator handles the math for you.
Roofing is the one project type where most people genuinely get the dumpster size wrong — not because they misjudge the volume, but because they don't account for the weight. A container full of old shingles looks like it has plenty of room left. It may also already be over the weight limit. Getting that calculation right before you book is exactly what this guide is for.
At Dumpstar Hauling & Dumpster Rental of Lexington, KY, we offer a 14-yard and a 20-yard roll-off dumpster — and roofing jobs are one of the most common projects we help size correctly before delivery. Here's the complete breakdown.

🧮 Find My Dumpster Size →Why Weight Matters More Than Volume for Roofing
With most debris — furniture, drywall, lumber — volume is the constraint. You fill the container and call for pickup. With roofing shingles, weight is the constraint. You can load a 20-yard dumpster to less than half its visual capacity with architectural shingles and already be at or near the weight limit.
Here's why: asphalt shingles are dense. A single roofing square — 100 square feet of shingles — weighs between 200 and 430 lbs depending on the type. Add underlayment, nails, flashing, and any damaged decking material, and the real-world weight per square runs even higher. Our 14-yard dumpster includes a 2-ton (4,000 lb) weight allowance. Our 20-yard includes 2.5 tons (5,000 lbs). Going over either limit costs $100 per ton in overage fees — which is why getting the size right before the job starts is the most important part of the whole process.
