Hail and Your Roof: Sizing a Tear-Off Dumpster in Thornton
On the Front Range, a single afternoon of hail can put a whole neighborhood into roof replacement at once - and a right-sized roll-off is the only practical way to clear a tear-off.

Few places in the country see hail like the Colorado Front Range. Thornton sits squarely in what insurers call Hail Alley, and a single severe storm can damage thousands of roofs in an afternoon. If you own a home here long enough, a tear-off is a question of when, not if - and the debris is a job all its own.
Living in Hail Alley
The stretch of high plains where Colorado, Wyoming and Nebraska meet is one of the most hail-prone regions on earth, and the north Denver metro is right in it. Spring and summer storms roll off the mountains and drop hail that can total a roof in minutes. When that happens, re-roofing demand across the metro spikes overnight.
Why shingles are all about weight
Asphalt shingles are heavy. A single layer stripped off an average roof weighs far more than its modest-looking pile suggests, and each additional layer multiplies it. That weight, not the volume, is what decides the container - which is why roofing goes in a smaller box filled to a level load rather than a large one.
Sizing by squares
Roofers measure in squares, each one a hundred square feet of roof. Give us the number of squares and the number of layers coming off and we can size it accurately. As a rough guide, a single-layer tear-off on an average home often suits a 15 or 20 yard, filled to weight. Multiple layers, a larger roof or heavy architectural shingles push toward a swap or a second container.
Why the box looks half empty
This is the part worth bracing for: a roofing container at its weight limit can look only half full. That is not a problem or a waste of space - it is the shingles reaching the legal hauling weight before they fill the volume. Sizing by squares rather than by eye is exactly how we avoid an overloaded, un-haulable box. And the debris goes to a licensed regional landfill, since no city resident program takes a contractor's roofing waste.
Getting a container fast after a storm
When a hailstorm hits and half the metro is re-roofing at once, containers get tight and the early callers get the easy scheduling. Being local, we can usually get a box out fast - but the sooner you call after the damage, the smoother the timing. Tell us the squares and layers and we will have the right container there for the tear-off.

What size dumpster for a roof tear-off?
It depends on squares and layers. A single-layer tear-off on an average home often suits a 15 or 20 yard filled to weight. Multiple layers or a large roof may need a swap - tell us the squares and we will size it.
Why does my roofing dumpster look half full when it's done?
Because shingles are dense and hit the legal hauling weight before they fill the volume. A box at its weight limit looking half empty is exactly right, which is why we size roofing by squares, not by eye.
Can I put roofing shingles in the city voucher?
No - the resident voucher is one covered load and excludes a contractor's roofing debris. Shingles go to a licensed regional landfill via a roll-off.
How fast can you deliver after a hailstorm?
Usually next day, often same day if a run is heading your way. Demand spikes across the metro after a big hail event, so calling early makes the scheduling easier.
