TL;DR
Asphalt shingles can often be recycled into road paving material, but the felt or synthetic underlayment underneath them usually cannot, which means a tear-off produces two piles instead of one. Mixing them costs money, because contaminated shingle loads lose the recycling rate. Underlayment disposal adds its own line to an average residential tear-off.
Roofers who recycle shingles already know this. Homeowners doing their own tear-off usually find out at the gate.
Why Does Underlayment Split From the Shingles?
Shingle recycling works because asphalt shingles are mostly asphalt binder and mineral granules, both of which go into hot mix asphalt for roads. Facilities that grind shingles hold tight specifications on what can be in the load.
Traditional felt underlayment is asphalt-saturated paper or fiberglass mat, so it is chemically compatible, and some shingle recyclers accept it. Many do not, because the paper fiber content and the volume of nails and staples in it complicate the grind.
Synthetic underlayment is a different material entirely. It is woven or spun polypropylene or polyethylene, sometimes with a coating, and it has no place in an asphalt shingle stream at all. It is also not recyclable in ordinary plastic streams, because it is a laminated, contaminated construction textile.
Peel-and-stick ice and water shield is the third category, an asphalt-rubber membrane with a poly film face. It is sticky, heavy, and universally rejected by shingle recyclers.
So the working rule is: shingles in one pile, everything under them in another. Our guide to disposing of old roofing shingles covers the shingle side.
Weight and Volume of a Tear-Off
Roofers measure in squares, where a square is 100 square feet of roof area.
| Component | Weight per square |
|---|---|
| Three-tab asphalt shingles, one layer | 200 to 250 pounds |
| Architectural shingles, one layer | 250 to 400 pounds |
| Number 15 felt underlayment | 15 to 20 pounds |
| Number 30 felt underlayment | 25 to 35 pounds |
| Synthetic underlayment | 4 to 10 pounds |
| Ice and water shield | 40 to 70 pounds |
A typical single-family roof is 20 to 30 squares. One layer of architectural shingles on a 25 square roof is 6,000 to 10,000 pounds, and the underlayment adds several hundred pounds on top.
Underlayment is light relative to shingles but bulky, because it comes off in tangled sheets rather than compact chunks. On volume-priced hauls, that tangle costs more than its weight suggests. Roll it or fold it as it comes off rather than throwing it loose.
The Nail Problem
A tear-off scatters an enormous number of fasteners. Every shingle course has nails through it, the underlayment has cap nails or staples every couple of feet, and the drip edge and flashing add more.
That makes the debris dangerous to handle, since torn felt with cap nails hanging out of it punctures gloves and tires. Rolled sheets are safer than loose ones. It also means the ground has to be swept. Run a rolling magnet over the drip line, driveway, lawn, and any path the debris traveled, more than once, and after the truck leaves rather than before.
Tarping the ground before the tear-off starts is the single highest-value prep step. It catches granules, nails, and torn felt, and turns cleanup from raking a lawn into folding a tarp.
Layers, Age, and What to Check
Two things are worth knowing before the first shingle comes off.
How many layers. Roofs are frequently shingled over rather than torn off, and two or three layers is common. Each layer roughly doubles or triples the debris tonnage, and it changes the haul plan completely. Check at a rake edge or a vent penetration.
How old. Asphalt roofing products made before roughly 1980, including some older roll roofing, mastics, flashing cements, and certain built-up roof systems, may contain asbestos. Modern asphalt shingles do not. If the building is older and there is built-up roofing, tar-and-gravel, or unidentified roofing mastic involved, stop and hire an accredited inspector to test. If it is positive, a licensed abatement contractor handles the removal. A junk hauler cannot accept suspected asbestos material.
Standard three-tab and architectural shingles from recent decades are not an asbestos concern, but old flat roof systems and roofing cement are worth a second look.

Current Market Reality
Most tear-off debris is hauled by the roofing contractor and bundled into the roofing price, which hides the real disposal cost. When it is bought separately, the drivers are tonnage, layer count, and whether the shingles can go to a recycler. A load contaminated with synthetic underlayment, plastic wrap, wood, or general trash loses the shingle recycling rate and gets priced as mixed construction debris. Tipping fees are charged per ton and rise steadily. Broader construction debris removal cost patterns apply, and the general sequencing advice in our guide to how to get rid of construction debris holds here too.
How tear-off disposal jobs compare with one another:
| Scope | Relative cost (lower to higher) |
|---|---|
| Underlayment only, small roof | Lower |
| Underlayment only, average roof | Lower |
| Full tear-off debris, single layer, 20 to 25 squares | Middle |
| Full tear-off debris, two layers | Higher |
| Ice and water shield surcharge | An add-on |
| Overweight surcharge per extra ton | An add-on, per ton |

Keeping the Load Clean
If the shingles are going to a recycler, the load specification is usually strict: asphalt shingles and nails only. No wood, no metal flashing, no plastic wrap, no bundle bands.
The practical setup is three staging points. Shingles into a dedicated bin or truck, underlayment and membrane rolled and stacked separately, and metal flashing, drip edge, and vents into a third pile, since clean sheet metal has scrap value. That third pile is worth making even on a small job, because metal that goes out with the shingles is both a contaminant and a lost credit. If siding is coming off in the same project, keep that separate again per our guide to vinyl siding tear-off disposal.
FAQ
Can roofing felt be recycled?
Sometimes, but not reliably. A few asphalt shingle recyclers accept asphalt-saturated felt because it is chemically similar. Many reject it over paper fiber and fastener content. Synthetic underlayment and peel-and-stick membrane are rejected everywhere and go to landfill.
How much does roofing underlayment weigh?
Number 15 felt runs 15 to 20 pounds per 100 square feet of roof, number 30 felt runs 25 to 35 pounds, and synthetic underlayment is much lighter at 4 to 10 pounds. Ice and water shield is the heavy one at 40 to 70 pounds per square.
Do old roofing materials contain asbestos?
Modern asphalt shingles do not. Some pre-1980 roofing products can, particularly built-up roofing, roll roofing, flashing cement, and roofing mastics. Have an accredited inspector test older flat roof systems before removal, and use a licensed abatement contractor if the result is positive.
Can I put tear-off debris in a regular dumpster?
Yes, if the container is rated for the weight, which most standard roll-offs are not at full volume. Shingles are dense enough that a 20 yard box filled with them will exceed the weight allowance. Providers usually offer a smaller dedicated roofing container instead.
What should I do about the nails afterward?
Run a rolling magnet over the drip line, driveway, walkways, and lawn several times, including after the debris truck leaves. Tarping the ground before the tear-off begins catches most fasteners and granules and makes cleanup dramatically faster.
Getting It Hauled Away
Tear-offs go smoothly when the material is separated before it hits the ground and the ground is tarped before anything comes down. Keep shingles clean for the recycler, roll the underlayment, and pile the metal on its own. Otesse can clear staged tear-off debris through our junk removal service.
