Roofing felt fits in a 20 yard dumpster, and it won't make a dent in the weight limit. What you're actually planning around is the shingles. They're heavier than most homeowners expect, and they're what determines whether your container handles the full job or triggers an overage charge on pickup day.
A full felt tear-off from a 2,000 sq ft roof produces somewhere between 150 and 540 lbs of material, depending on the product. Your shingles from that same area can push past 6,000 lbs. That gap is where the real planning happens, and it's what this page is built around.
When your project involves more than roofing debris — old appliances, furniture, or other cleanout items you're clearing at the same time — our appliance removal guide walks you through what to do with items like refrigerators before the truck arrives. And when the job outgrows a rental container, Jiffy Junk's full-service removal handles loading, hauling, and eco-responsible disposal from start to finish. Here's everything you need to know.
TL;DR Quick Answers
TL;DR Quick Answers
Short on time? Here's what you need to know.
Does roofing felt fit in a 20 yard dumpster? Yes. Felt is lightweight and compressible. It's almost never the limiting factor.
What actually limits my 20 yard dumpster? Shingle weight. Asphalt shingles are dense and heavy per square, and they add up fast.
Can felt and shingles go in the same container? Yes. They're part of the same roofing waste stream. Keep household trash out of the load.
How heavy is roofing felt? #15 felt: 7.5 to 12.5 lbs per roofing square. #30 felt: 16 to 27 lbs per square. Synthetic runs lighter than both.
What size dumpster fits a standard re-roof? A 20 yard container works for most 1,000 to 2,500 sq ft single-layer residential projects.
What if I have more debris than the container can carry? Jiffy Junk's full-service removal handles any volume. No container required, no weight limits to manage.
Top Takeaways
Top Takeaways
Roofing felt and underlayment fit in a 20 yard dumpster. Felt is one of the lightest and most compressible materials you'll pull off a roof.
Shingle weight drives your container decision, not felt weight. Run your shingle calculation first, then add underlayment as a minor variable.
A 20 yard dumpster typically measures 22' x 8' x 4.5' and holds roughly six pickup truck loads. That size handles most residential re-roofs.
Roll or fold your felt tightly before loading. Loose felt eats container space fast.
All four standard underlayment types (asphalt-saturated felt, synthetic, self-adhering, and ice-and-water shield) go in standard dumpsters. For how your new underlayment affects attic airflow after the project wraps, review HVAC system impacts with your contractor before you select a replacement product.
Rain adds real weight to debris. Wet roofing materials can push you past your container's cap before pickup. Review regional rental rates before booking so overage charges don't catch you off guard.
When a single container isn't the right fit, Jiffy Junk's full-service team handles any volume. Our 20-yard dumpster guide gives you a full size and cost comparison.
What Is a 20 Yard Dumpster?
What Is a 20 Yard Dumpster?
A 20 yard dumpster, also called a 20 cubic yard roll-off container, is one of the most popular rental sizes in the country. Standard dimensions run 22 feet long, 8 feet wide, and 4.5 feet tall, giving you about 20 cubic yards of capacity or roughly six full pickup truck loads.
The 20 yard size handles residential re-roofs on homes between 1,000 and 3,000 square feet well. If your timeline is tight, same-day rental options are worth a look before you commit. And if you're still deciding whether the 20 yard container is the right investment for your budget, this guide to best value sizes breaks down cost-per-yard across the most common options.
Roofing Felt and Underlayment: Weight Basics
Traditional #15 felt underlayment weighs 7.5 to 12.5 lbs per roofing square. #30 felt runs 16 to 27 lbs per square, according to DECRA Roofing Systems. Synthetic underlayment weighs less than either. A full felt tear-off from a 2,000 sq ft roof, which covers 20 roofing squares, produces roughly 150 to 540 lbs of material depending on the product type.
Asphalt shingles weigh 240 to 350+ lbs per square. Felt barely registers next to that. For a clear look at why weight — not volume — drives overage charges, this pricing factors breakdown is worth a few minutes before you book your container.
Roofing felt won't push your 20 yard dumpster over its weight limit. Your shingles are the weight story. Felt just comes along for the ride.
Can Roofing Felt and Shingles Go in the Same Dumpster?
Yes. Felt paper, shingles, nails, and small amounts of metal flashing all belong to the same roofing waste stream and can share a container. This construction debris guide covers what co-mingles safely in a roll-off and what changes the load classification. What you want to keep out is unrelated waste. Household trash or construction materials from other projects can reclassify the load and raise your disposal fee when the container hits the scale.
One practical step before you start loading: roll or fold your felt tightly. Loose felt takes up three to four times the container space that a compressed roll does. A little organization at the start keeps room for everything else.
Types of Underlayment and How They Dispose
Not all underlayment handles the same way. Here's what you're working with on most residential projects:
Asphalt-Saturated Felt (#15 / #30) Lightweight and compressible. Standard roll-off dumpsters accept it in virtually all regions. A natural fit for 20 yard containers.
Synthetic (Polyethylene/Polypropylene) The lightest option. Rolls up easily and works with any standard roll-off container.
Self-Adhering / Peel-and-Stick Slightly heavier due to the adhesive backing. Standard dumpsters take it. Separate into sections before loading to make handling easier.
Ice and Water Shield Dense and sticky. Standard containers accept it, but factor the added weight into your estimate before you book.
Underlayment choice also affects your attic once the project wraps. According to HVAC Info Hub, moisture-permeable underlayments help maintain healthy attic airflow, which reduces long-term strain on your HVAC efficiency. Before you select a replacement product, confirm it's compatible with your home's attic ventilation setup.
One thing worth flagging before you start: if your home was built before 1980, have a contractor check for asbestos-based roofing materials. Those require certified abatement. They do not go in a standard dumpster.
Understanding Dumpster Rental Pricing for Roofing Projects
Rental rates shift based on your region, container size, weight allowance, and how long you need the unit. For smaller tear-offs, this small project pricing breakdown gives you a solid budget baseline. If you're in a rural or mid-sized market, regional rental rates can look very different from urban quotes, so always get a local number before committing.
Nationally, a 20 yard roll-off runs $300 to $600 [VERIFY] for a standard rental window. Overage fees kick in when you exceed the included weight limit, typically at $50 to $100 per ton. On a multi-layer asphalt tear-off, those charges can show up before you're halfway through the pile.
When a Dumpster Isn't the Right Call
A 20 yard dumpster handles most residential roofing jobs. Multiple shingle layers, a large commercial property, a tight driveway, or a mixed debris load can shift the math quickly. Those are the situations where homeowners get caught with a full container and a bill they didn't plan for.
That's where Jiffy Junk comes in. Our licensed, insured crews do the loading, haul everything away, and handle eco-responsible disposal of your felt, shingles, and anything else coming down. No container to schedule. No permit research. No overage fees on your invoice.
You point to the pile. We take care of the rest. That's the White Glove Treatment, and we're not done until you're happy with the result. For a full size and cost comparison before you decide, see our 20-yard dumpster guide.
"In over a decade of nationwide roofing removals, the number-one mistake we see is homeowners sizing their dumpster by volume instead of weight. Roofing felt is almost never the problem, but two layers of architectural shingles can push a 20 yard container past its legal limit before you're halfway through the pile."

3 Statistics Worth Knowing
3 Statistics Worth Knowing
These numbers put roofing debris and disposal planning in perspective before the first shingle comes down.
STAT 1 An estimated 5 million roofs are installed or replaced in the United States every year. Source: RubyHome.com — Roofing Statistics (https://www.rubyhome.com/blog/roofing-stats/)
That's 5 million projects producing shingles, felt, flashing, underlayment, and nails that all need somewhere to go. Efficient, responsible disposal isn't optional — it's part of the job.
STAT 2 Asphalt shingles appear in approximately 80% of all residential U.S. roofing projects, making them — and their underlayment — the dominant debris type in dumpsters nationwide. Source: Fixr.com — U.S. Roofing Industry Statistics 2025 (https://www.fixr.com/articles/us-roofing-industry-statistics)
If you're working with asphalt shingles, you're in the majority. You're also working with one of the heaviest standard roofing materials available. Pairing shingles and felt in a 20 yard container is workable, but calculate shingle weight before you book anything.
STAT 3 Modern #15 felt underlayment typically weighs 7.5 to 12.5 lbs per roofing square. #30 felt runs 16 to 27 lbs per square. Asphalt shingles run 240 to 350+ lbs per square. Source: DECRA Roofing Systems — Understanding Roof Underlayment (https://www.decra.com/pro/understanding-roof-underlayment-1)
That weight gap is why felt never determines your container size. A full layer of #30 felt across a 2,000 sq ft roof weighs 320 to 540 lbs. The same area in architectural shingles weighs 5,000 to 7,000 lbs. Those two numbers don't belong in the same planning conversation.
Our Take: Dumpster Rentals Work — Until They Don't
Our Take: Dumpster Rentals Work — Until They Don't
A 20 yard dumpster gets the job done for most single-layer residential re-roofs under 2,500 square feet. Shingles, felt, nails, and flashing fit, and the weight usually stays within range.
Here's what rental companies don't lead with: overage charges arrive fast. Two layers of old architectural shingles on a 2,000 sq ft roof can push past 10,000 lbs, which is potentially double the legal carry limit for a 20 yard container on public roads. Rain soaking into the debris before pickup pushes that number further still. Overages are one of the biggest pricing factors homeowners don't account for until the invoice lands.
Do the weight math before you book. Know your shingle type. Check for multiple layers. Ask your rental provider for their exact weight cap and their per-ton overage rate. For smaller projects, comparing small project pricing against full-service removal often makes Jiffy Junk the clearer call, financially and logistically.
If the numbers don't work out, or you'd rather not manage a container sitting in your driveway all week, our full-service removal is the answer. We handle the logistics, the loading, and eco-responsible disposal — so you put your energy into the new roof, not the old one.
Frequently Asked Questions
Frequently Asked Questions
Will roofing felt and underlayment fit in a 20 yard dumpster?
Will roofing felt and underlayment fit in a 20 yard dumpster?
Yes. Standard #15 felt weighs as little as 7.5 lbs per roofing square and compresses tightly when you roll it. A full residential tear-off of felt alone rarely exceeds 500 lbs, which falls well within the weight limit of any standard 20 yard container.
Can I put roofing shingles and felt in the same dumpster?
Can I put roofing shingles and felt in the same dumpster?
Yes. Shingles, felt paper, underlayment, nails, and small amounts of flashing all belong to the same roofing waste stream. This construction debris guide shows what co-mingles safely in a roll-off. Keep household trash and unrelated construction debris out of the container. Mixing them in can reclassify your load and raise your disposal fee at the scale.
How heavy is a 20 yard dumpster load of roofing debris?
How heavy is a 20 yard dumpster load of roofing debris?
It depends on your shingle type and how many layers you're removing. Single-layer 3-tab asphalt shingles on a 2,000 sq ft roof run 4,000 to 6,000 lbs. Architectural shingles or a two-layer tear-off can reach 10,000 lbs or more. Most 20 yard dumpsters cap out between 4,000 and 6,000 lbs. Confirm the exact limit with your rental provider before you load anything.
Do I need a permit to place a 20 yard dumpster?
Do I need a permit to place a 20 yard dumpster?
It depends on where the container goes. Dumpsters on private driveways typically don't need a permit. Street placement usually does. Check with your local municipality before delivery to avoid fines or a forced removal.
Does underlayment choice affect my HVAC or attic ventilation?
Does underlayment choice affect my HVAC or attic ventilation?
It does, and the question is worth answering before you select your replacement product. Vapor-impermeable underlayments, which covers most synthetics, restrict upward drying of the roof deck and can affect attic humidity and air quality over time. For how that connects to your home's HVAC systems, especially in older homes, the HVAC report resource is a reliable place to start. And if moisture-related concerns come up during a larger cleanout — including checking soft furnishings or mattresses that spent time in a damp space — our bed bug guide covers early warning signs before those items get hauled.
Is roofing underlayment recyclable?
Is roofing underlayment recyclable?
Some synthetic underlayment products are recyclable, depending on what facilities operate in your area. Asphalt-saturated felt and peel-and-stick materials typically go to landfill. Jiffy Junk recycles and donates materials whenever possible. That commitment is built into every job we take on, not added as an afterthought.
What if my roofing debris exceeds the dumpster weight limit?
What if my roofing debris exceeds the dumpster weight limit?
You'll face overage charges, typically $50 to $100 per ton above the cap. For larger tear-offs or multi-layer jobs, a second container, a 30 yard dumpster, or Jiffy Junk's full-service removal are all worth considering. Before you commit to a container size, this pricing factors breakdown is a quick read that could prevent a real cost surprise.
