Roof Replacement Dumpster Rental: Sizing for Tear-Offs

Roofing tear-offs are one of the heaviest debris streams a homeowner is likely to generate. A square of asphalt shingles weighs about 250 pounds. Multiply that across a typical home and you’re at multiple tons of pure shingle weight, before underlayment, flashing, decking, and any old felt come into play.

Sizing a roll-off for roofing is mostly a weight problem, not a volume problem. Here’s how to think about it.

The weight reality

Asphalt shingles average about 250 lb per “square” — 100 square feet of roof area. A few real numbers:

• 20 squares (small home): ~5,000 lb / 2.5 tons
• 30 squares (average home): ~7,500 lb / 3.75 tons
• 40 squares (larger home): ~10,000 lb / 5 tons
• 50 squares (large or commercial): ~12,500 lb / 6.25 tons

Three-tab shingles run on the lower end of that range. Architectural (laminated) shingles run heavier — sometimes 350 lb per square for premium products. Concrete tile and slate are dramatically heavier still.

Add another 10–15% for underlayment, flashing, and miscellaneous tear-off material.

How that translates to size

Our 15 yard handles up to roughly 25 squares of asphalt comfortably. Past that, you’re approaching the weight limit.

A 30 yard handles up to about 50 squares of asphalt — again, weight-limited well before volume.

For very large roofs, or jobs combining tear-off with other significant debris (decking replacement, structural work), the 30 yard is right.

For smaller homes, the 15 is plenty and easier to live with on the driveway.

Timing the rental

Roofing crews work fast. A typical residential tear-and-replace runs 1–3 days. The container needs to be on site for the tear-off phase, which happens on day one.

Day before tear-off: Box delivered. We try to deliver the day before for roofing jobs so the crew arrives ready to work.

Day of tear-off: Heaviest single day of loading. The crew strips the roof and the debris goes directly into the box, often via chute.

Day of new install: Lighter loading. Underlayment scraps, ridge cap pieces, packaging.

Final day: Cleanup and pickup.

For most jobs, a 7-day rental window covers the project comfortably. Same-day pickup after job completion is usually available.

Where the dumpster goes

Roofing crews want the box within 20 feet of the home, ideally where the chute can run from the eave directly into the dumpster. Practical placement notes:

Driveway, near the house corner — most common Side yard, if accessible — works for tight driveways Street placement — only if necessary; some Boerne neighborhoods require a permit

Avoid placing the box where it blocks the homeowner’s car, the crew’s ladder access, or the staging area for new shingles. Most experienced roofers will direct placement; if you’re not sure, ask the contractor where they want it.

We always set protective boards under the wheels — concrete and asphalt driveways take a beating from a loaded roll-off without protection.

What goes in (the easy part)

Allowed:

• Asphalt shingles (three-tab, architectural, designer)
• Felt and synthetic underlayment
• Drip edge and flashing
• Old wood decking (if being replaced)
• Insulation removed from underlayment
• Vent boots and pipe flashing
• Old gutters (often replaced at the same time)
• Soffit and fascia material (if being replaced)
• Skylights (with glass intact)

Allowed but watch:

• Concrete or clay tile — much heavier; weight-only constraint
• Slate — extremely heavy; usually a special-handling job
• Metal roofing — light by volume but bulky; cut down where possible

What’s not allowed

The standard roll-off rules apply:

• Asbestos-containing materials. Older roofs (pre-1980) sometimes have asbestos in the underlayment or in transite-style siding under the eaves. If you suspect any, get it tested before tear-off.
• Liquid roofing products — old roof coating, sealants in liquid form, leftover tar
• Propane tanks that may have been used by the crew (return to the supplier)
• Tar pots with residual liquid

Cured tar on materials is fine. Liquid tar is not.

Architectural vs three-tab: a sizing nuance

Three-tab shingles weigh about 230 lb per square. Architectural shingles run 250–350 lb per square depending on the brand and “designer” features. Premium designer shingles can hit 400 lb.

If your home has heavy architectural shingles being replaced, treat the weight at the high end of the range. A 30-square architectural roof can weigh 9,000 lb just from the shingles — into the 4.5-ton range with underlayment and flashing.

This usually doesn’t change which size box you need (a 15 still works for most residential roofs). It just changes how aggressively you should pack heavy items.

Multiple-layer tear-offs

If your existing roof has two or three layers of shingles (common on older homes that had a “lay-over” rather than a full tear-off in the past), the weight roughly doubles or triples per square.

A 25-square roof with three layers is effectively a 75-square single-layer load — about 19,000 lb / 9.5 tons of shingles alone. That’s well past what fits in a 15 yard. For multi-layer roofs:

• 20 squares, 2 layers: 15 yard with weight planning
• 30 squares, 2 layers: 30 yard
• Any 3-layer tear-off: 30 yard, possibly with a swap

Roofers know how to assess existing roof layers from the visible profile and from cores during inspection. Ask them.

Decking replacement

If the project includes replacing old wood decking (sheathing) under the shingles — common when there’s been water damage or aged plywood — you’ll add another 1.5–2.5 cubic yards per 1,000 sq ft of roof area. The wood is light compared to shingles but takes volume.

Most roofing jobs include some decking replacement (a few sheets here and there). A full deck replacement is more like 30–40% of total roof area in our experience.

What to ask your roofer before booking

A few questions that help us size correctly:

1. How many squares? Get the exact number from the estimate.
2. What kind of shingles are coming off (three-tab vs architectural vs designer)?
3. How many layers?
4. Will they be replacing decking? (Often yes.)
5. Will they be doing other work at the same time (siding, gutters, skylights)?
6. What’s their preferred placement for the dumpster?

With those answers, we can size correctly the first time and have the box where they want it.

If you’re scheduling a roof replacement in Boerne and the Hill Country, Mount Vernon, or Northeast Texas, give us a holler at (903) 806-4181 or book online once you have a start date. We can almost always get a container delivered the day before the crew arrives.
