Roof Replacement Dumpster Size Guide

Calculate the right dumpster size for your roofing project based on square footage and materials

Quick Answer: Most residential roof replacements need a 20-30 yard dumpster. Calculate 1 yard per 100 sq ft of roof for asphalt shingles, or use our calculator below.

Calculate Your Roof Dumpster Size

Roof Replacement Dumpster Size Chart

Roof Square Footage	Material Type	Recommended Dumpster	Estimated Cost
1,000-1,500 sq ft	Asphalt shingles	15-20 yard dumpster	$380-480
1,500-2,000 sq ft	Asphalt shingles	20-30 yard dumpster	$450-580
2,000-2,500 sq ft	Asphalt shingles	30 yard dumpster	$550-650
2,500+ sq ft	Asphalt shingles	30-40 yard dumpster	$650-750
Any size	Tile or slate	Add 1 size larger	+ Weight fees possible

Important: These estimates assume single-layer removal. If your roof has multiple layers of shingles, increase the dumpster size accordingly (typically add 50% more capacity).

Roofing Material Weight and Volume Guide

Asphalt Shingles

Weight: 200-350 lbs per 100 sq ft
Volume: ~1 cubic yard per 100 sq ft
Layers: Multiple layers multiply weight
Disposal: Most common, easy to dispose

Heavy Materials

Clay tiles: 600-800 lbs per 100 sq ft
Slate: 800-1,200 lbs per 100 sq ft
Concrete tiles: 400-600 lbs per 100 sq ft
Cedar shakes: 150-250 lbs per 100 sq ft

Weight Limit Warning

Tile, slate, and concrete roofing materials are extremely heavy. A 20-yard dumpster can easily exceed its 3-4 ton weight limit with just 1,000 sq ft of tile removal. Consider multiple smaller dumpsters or arrange for special heavy debris pickup.

Factors That Affect Roof Dumpster Size

Number of Layers

Single Layer

Use standard calculations. Most efficient for dumpster sizing.

Double Layer

Add 75-100% to dumpster size. Weight considerations increase significantly.

Triple+ Layers

Consider multiple dumpsters or professional removal due to extreme weight.

Roof Complexity

Simple gable roof: Standard calculations apply
Hip roof: Add 10-15% for additional surface area
Complex roof with dormers: Add 20-25% for extra cutting and waste
Steep pitch (over 6/12): More difficult removal, potential for more breakage

Additional Debris

Gutters and downspouts: Usually minimal space needed
Fascia and trim replacement: Add 10-15% capacity
Chimney work: Brick and mortar are extremely heavy
Decking replacement: Plywood/OSB adds significant volume

What Can and Cannot Go in Your Roofing Dumpster

✅ Acceptable Roofing Debris

Asphalt shingles and underlayment
Roof decking (plywood, OSB)
Roofing nails and staples
Flashing (small amounts)
Ridge vents and caps
Gutters (aluminum, vinyl)
Wood trim and fascia boards
Insulation materials

❌ Items Requiring Special Disposal

Asbestos shingles (requires certified removal)
Large amounts of metal flashing (recycle separately)
Satellite dishes and equipment
Solar panels and wiring
Masonry and concrete (extremely heavy)
Paint and chemical products
Tar and liquid roofing materials

Roof Replacement Timeline and Dumpster Scheduling

Day 1: Tear-Off (Highest Debris Volume)

Complete removal of old roofing materials. Generates 80-90% of total debris. Schedule dumpster delivery for morning of this day.

Day 2: Decking Repairs

Replace damaged decking. Minimal debris unless extensive repairs needed. Old plywood/OSB disposal.

Days 3-4: Installation

New shingle installation. Mainly packaging waste and cut-offs. Usually fits in existing dumpster space.

Pro Tip: Most roofing contractors prefer same-day dumpster delivery and pickup for tear-off day, then a second smaller dumpster for the installation phase if needed. This minimizes rental costs while ensuring adequate capacity.

Cost-Saving Tips for Roof Replacement Dumpsters

Before the Project

Get multiple quotes - Dumpster prices vary significantly
Check weight limits - Avoid overage fees for heavy materials
Coordinate with roofer - Many contractors have preferred vendors
Consider timing - Avoid peak storm seasons when prices spike

During the Project

Separate metal - Take copper and aluminum to scrap yards
Load efficiently - Break up large decking pieces
Monitor weight - Stop loading if approaching limits
Schedule pickup promptly - Avoid extra daily fees

Permit and Placement Considerations

Dumpster Placement

Safety Priority: Roofing dumpsters must be positioned safely for debris dropping. Consider fall zones and property damage protection.

Close to work area - Minimize debris throwing distance
Ground protection - Use plywood on driveways and lawns
Clear overhead - Avoid power lines and tree branches
Neighbor consideration - Ensure placement doesn't block access

Permit Requirements

Private property - Usually no permit required
Street placement - Permit typically required from city/county
HOA restrictions - Check community rules and notification requirements
Time limits - Some areas restrict how long dumpsters can remain

Common Roof Replacement Dumpster Mistakes

Size Mistakes

Underestimating layers - Multiple shingle layers create much more debris
Ignoring material type - Tile and slate are much heavier than shingles
Forgetting decking - Plywood replacement adds significant volume
Not planning for weather delays - Extended rental periods cost extra

Placement Mistakes

Too far from house - Increases labor and cleanup time
Wrong side of house - Not considering wind direction and access
Blocking access - Preventing emergency vehicle or neighbor access
No ground protection - Damage to driveways and landscaping

Frequently Asked Questions

How do I calculate my roof's square footage?

For simple roofs, multiply length × width of your house and add 10% for overhang. For complex roofs, measure each section separately. Remember, roof square footage is typically 10-40% larger than your home's footprint due to pitch and overhangs.

Can I put gutters in the same dumpster as shingles?

Yes, aluminum and vinyl gutters can go in roofing dumpsters. However, if you have large amounts of metal gutters, consider taking them to a scrap yard for cash instead of paying disposal fees.

What if my roof has multiple layers of shingles?

Multiple layers significantly increase debris volume and weight. For double layers, increase your dumpster size by 75-100%. For triple layers, consider renting two separate dumpsters to avoid weight overages.

How close to my house can the dumpster be placed?

Dumpsters should be positioned to minimize throwing distance while maintaining safety. Typically 10-20 feet from the house is ideal, considering fall zones and roof pitch. Always protect the ground surface and ensure safe access.
