The Maryville Roofer's Checklist: Choosing the Right Dumpster Size for Every Job
Choosing the wrong dumpster size can derail your roofing project before you even break out the tear-off tools. Order too small, and you're stuck paying for an extra pickup or overflow fees. Order too large, and you've wasted money on capacity you'll never use. For roofing contractors working across Maryville, Alcoa, and Blount County, getting the dumpster size right the first time isn't just about convenience—it's about protecting your profit margins and keeping projects on schedule.
At Two Gen Vets, we've worked with hundreds of roofing contractors throughout the Maryville area, and we've seen every sizing scenario imaginable. This comprehensive guide will help you choose the perfect dumpster rental for any roofing job, from small residential tear-offs to large commercial projects.
Understanding Dumpster Measurements: What Do the Numbers Mean?
Before we dive into specific roofing scenarios, let's clarify what dumpster sizes actually represent. When you hear "20-yard dumpster" or "30-yard dumpster," that number refers to cubic yards of capacity—not the physical dimensions of the container.
20-Yard Dumpster Dimensions
A 20-yard dumpster typically measures approximately 22 feet long, 8 feet wide, and 4 feet high. This gives you 20 cubic yards of debris capacity, which translates to roughly:
110-130 bundles of architectural shingles
3-4 pickup truck loads of roofing debris
Coverage for approximately 1,500-2,000 square feet of single-layer roof tear-off
30-Yard Dumpster Dimensions
A 30-yard dumpster measures approximately 22 feet long, 8 feet wide, and 6 feet high. The extra height provides 30 cubic yards of capacity:
165-200 bundles of architectural shingles
5-6 pickup truck loads of roofing debris
Coverage for approximately 2,500-3,500 square feet of single-layer roof tear-off
The Critical Factors That Determine Dumpster Size
Experienced Maryville roofers know that several key factors influence which dumpster size you'll need. Let's break down each consideration:
1. Square Footage of the Roof
This is your starting point for any calculation. Measure the roof area (not the floor plan of the house—the actual roof surface including pitch). A 2,000 square foot home might have 2,400 square feet of actual roof surface once you account for pitch and overhangs.
Quick Reference:
Under 1,500 sq ft of roof → Likely 20-yard dumpster
1,500-2,500 sq ft of roof → Could go either way; depends on other factors
Over 2,500 sq ft of roof → Probably 30-yard dumpster
2. Number of Existing Shingle Layers
This is where many contractors miscalculate. A single layer of architectural shingles produces significantly less waste than multiple layers of old, heavy shingles.
One Layer: Standard residential roofs with a single layer of architectural shingles are straightforward. Use the square footage guidelines above.
Two Layers: If you're tearing off two layers, you're essentially doubling your debris volume. A 1,800 square foot roof with two layers will fill a dumpster the same as a 3,600 square foot single-layer roof. Always bump up to the next size when dealing with multiple layers.
Three Layers (or Old Cedar Shakes): Rare in newer construction, but common in older Maryville homes. Three layers or cedar shake removal almost always requires a 30-yard dumpster, even for modest-sized roofs. Cedar shakes, in particular, are bulky and take up significant space.
3. Additional Roofing Components
Don't forget about these materials that add to your debris volume:
Underlayment and felt paper: Minimal volume but still counts
Wood decking replacement: Rotten or damaged plywood/OSB adds considerable weight and volume
Drip edge, flashing, and trim: Metal components don't compress, so they take up space
Ridge vents and caps: Bulky items that occupy valuable dumpster real estate
Gutters: If replacing gutters as part of the project, factor in their volume
Old satellite dishes or antennas: Homeowners often ask for removal during re-roofing
4. Job Site Constraints
Sometimes the best dumpster size isn't about capacity—it's about what physically fits on the property.
Driveway Space: Maryville has many beautiful older homes with narrow driveways or limited street access. A 20-yard dumpster's shorter height might be preferable even if a 30-yard would be more convenient, simply because it's easier to position and access.
HOA Restrictions: Some Maryville neighborhoods have homeowner associations with strict rules about dumpster placement and duration. Confirm any restrictions before ordering.
Tree Coverage and Overhead Lines: Properties with mature trees or low-hanging power lines may limit where you can safely place a taller 30-yard dumpster.
5. Project Timeline and Crew Size
How quickly you'll fill the dumpster matters more than you might think.
Fast Crews: If you run a large, efficient crew that can tear off an entire roof in a day, you want adequate capacity to handle everything at once. Running out of room mid-project means slowing down your tear-off or paying for an emergency pickup.
Extended Projects: If weather, scheduling, or the scope of work means your project will span multiple days or weeks, you might opt for a smaller dumpster with a planned swap-out rather than having a massive container sitting on the property for an extended period.
Dumpster Size Recommendations by Project Type
Now let's get specific. Here's how to size dumpsters for the most common roofing projects Maryville contractors encounter:
Small Residential Roof (Under 1,500 sq ft)
Typical Projects: Small ranch homes, garages, sheds, carports
Recommended Size: 20-yard dumpster
Why It Works: These projects generate 80-120 bundles of shingle debris plus underlayment and miscellaneous materials. A 20-yard container provides adequate capacity with room to spare, and its compact footprint fits well in most residential driveways.
Pro Tip: If there's any possibility of wood decking repair, consider a 30-yard to give yourself breathing room. Nothing's worse than having to carefully Tetris-pack debris because you're running out of space.
Standard Residential Roof (1,500-2,200 sq ft)
Typical Projects: Standard single-family homes, split-level residences
Recommended Size: 20-yard for single layer; 30-yard for two layers
Why It Works: This is the sweet spot where your decision point becomes critical. A single layer of architectural shingles on a 2,000 square foot roof will comfortably fit in a 20-yard dumpster. But add a second layer, some rotten decking, or bulky ridge vents, and you'll be glad you upgraded to a 30-yard.
Pro Tip: When in doubt on these mid-size projects, ask yourself: "Would I rather have 10 extra cubic yards I don't need, or run out of space with 10% of the debris still on the ground?" Most experienced contractors choose the former.
Large Residential Roof (2,200-3,500 sq ft)
Typical Projects: Large two-story homes, homes with complex roof lines, properties with attached garages
Recommended Size: 30-yard dumpster (always)
Why It Works: These roofs produce 150-200+ bundles of debris. Even with a single layer of shingles, you're pushing the absolute maximum capacity of a 20-yard dumpster. The modest cost difference between sizes is insignificant compared to the risk of needing an emergency pickup or extension.
Pro Tip: Large roofs in established Maryville neighborhoods often have beautiful, mature landscaping. Make sure your dumpster rental service uses protective wood boards under the container to prevent driveway damage—this is standard practice with Two Gen Vets.
Very Large or Complex Residential Roofs (Over 3,500 sq ft)
Typical Projects: Estate homes, properties with multiple roof planes, Tudor-style homes with steep pitches
Recommended Size: 30-yard dumpster, potentially with a mid-project swap
Why It Works: At this scale, you're generating commercial-level debris volumes. A single 30-yard dumpster might not be sufficient, especially if you encounter multiple shingle layers or extensive decking damage.
Pro Tip: Coordinate with your dumpster provider before the project starts. Two Gen Vets can schedule a mid-project swap where we remove a full 30-yard container and immediately deliver an empty one, keeping your job site organized and your crew productive.
Multi-Family or Light Commercial Projects
Typical Projects: Duplexes, fourplexes, small apartment buildings, retail buildings
Recommended Size: Multiple 30-yard dumpsters or coordinated swap schedule
Why It Works: Commercial projects generate debris volumes that exceed even the largest residential dumpster's capacity. The key is planning your waste management strategy before the first shingle comes off.
Pro Tip: For commercial work in Maryville, discuss staging and logistics with Two Gen Vets ahead of time. We can create a customized dumpster rental delivery and pickup schedule that keeps your site clean without requiring excessive space for multiple containers.
Special Roofing Scenarios: When Standard Guidelines Don't Apply
Not every roofing job fits neatly into the categories above. Here's how to handle unique situations:
Metal Roof Over Shingle Tear-Off
If you're removing old shingles to install a metal roof, the shingle debris follows standard calculations. However, if you're also removing old metal roofing, remember that metal doesn't compress well and takes up significant space relative to its weight. Consider upsizing your dumpster or ordering a dedicated metal recycling container.
Slate or Tile Roof Removal
Slate and tile are extremely heavy and create different waste profiles than asphalt shingles. A 1,500 square foot slate roof can easily fill a 30-yard dumpster due to weight limits rather than volume constraints. Always consult with your dumpster provider about weight restrictions for these specialty materials.
Storm Damage or Insurance Restoration
Storm-damaged roofs often involve more than just shingles. You might be removing damaged decking, blown-off sections that landed in the yard, waterlogged insulation, or even interior drywall and ceiling materials. These projects almost always require larger dumpsters or multiple containers.
Historic Home Renovations
Older homes in Maryville's historic districts often have unique roofing materials—wooden shakes, multiple layers of different materials, or even original slate. These projects require careful planning and often benefit from oversized dumpsters to accommodate unpredictable debris volumes.
The True Cost of Choosing Wrong: A Real-World Example
Let's look at a scenario that plays out regularly across Blount County:
A contractor bids a 2,000 square foot residential re-roof with what appears to be a single layer of shingles. To save $75, they order a 20-yard dumpster instead of a 30-yard. During tear-off, the crew discovers:
Actually two layers of shingles (the second layer was hidden)
Three sheets of rotten decking that need replacement
Old wooden ridge vents that are bulky and don't compress
By mid-afternoon, the 20-yard dumpster is completely full—but there's still 30% of the roof to tear off. The contractor has three options:
Pay for emergency pickup and new delivery: $200-300 extra, plus project delay
Pile debris on the ground: Creates safety hazards, looks unprofessional, and might violate local ordinances
Carefully crush and pack debris: Wastes hours of crew time (costing more than the dumpster upgrade would have)
The contractor "saved" $75 by choosing the smaller dumpster but ended up spending $300+ in extra costs and delays. This scenario happens more often than you'd think—and it's completely avoidable with proper planning.

Common Mistakes Maryville Roofers Make (And How to Avoid Them)
Mistake #1: Using House Square Footage Instead of Roof Square Footage
Your client's 2,000 square foot home doesn't have a 2,000 square foot roof. Once you account for pitch, overhangs, and roof complexity, the actual roof surface could be 2,400-2,800 square feet. Always calculate based on actual roof measurements, not floor plans.
Mistake #2: Forgetting to Account for Unknowns
You won't know what's under those shingles until you start tearing off. Hidden second layers, rotten decking, and unexpected materials are common. Build in a buffer—if the math says you're right at the edge of a 20-yard capacity, get the 30-yard.
Mistake #3: Prioritizing Cost Over Convenience
The cost difference between a 20-yard and 30-yard dumpster is modest—often $50-100. But running out of capacity mid-project can cost you hundreds in delays, extra deliveries, and crew time. Don't let a small upfront savings create a big problem later.
Mistake #4: Not Considering Job Site Logistics
The perfect-sized dumpster doesn't matter if it won't fit in the driveway or if HOA restrictions prohibit its placement. Always scout the job site before ordering and discuss any constraints with your dumpster provider.
Mistake #5: Waiting Until the Last Minute
Dumpster availability can be limited during peak roofing season (spring and fall in Tennessee). Don't wait until the day before your project starts to order. Book as soon as you've scheduled the job, and confirm delivery details a few days in advance.
Questions to Ask Before Ordering Your Dumpster
Make sure you're getting the right size and service by asking these questions:
"What's included in the rental price?" Make sure you understand if delivery, pickup, disposal, and rental period are all included or if there are separate charges.
"What are the weight limits?" Roofing debris is heavy. Confirm that the quoted price includes adequate weight allowance for your project type.
"Do you provide driveway protection?" This should be standard, but always confirm. You don't want to damage your customer's property.
"What's your pickup process?" Will they sweep for nails? How much notice do you need to give for pickup? Is there flexibility if weather delays your project?
"Can you deliver on short notice?" Weather delays are inevitable in roofing. Make sure your dumpster provider can accommodate last-minute schedule changes.
"What's your policy on overfilling?" Understand what happens if you exceed capacity—some companies charge hefty overage fees, while others have more flexible policies.
