Where Old Shingles Go: Recycling Notes From Macomb Tear-Offs
Every tear-off ends with a dumpster full of old shingles at the curb. Most homeowners never ask where it goes next. Some of it has a second life as road asphalt. Most of it, honestly, still does not.
A tear-off dumpster looks like waste. Underneath the tangle of torn tabs and nail strips, an asphalt shingle is mostly the same material a paving crew lays down on a county road: asphalt binder, crushed stone or slag, and a reinforcing mat. That overlap is the whole reason shingle recycling exists, and why the dumpster in your driveway is not automatically headed to a landfill. Whether it actually gets recycled depends on where the roof sits and which hauler picks up the load. This note is about that path, honestly, without pretending every shingle in Macomb County ends up in a road.
01 /What is actually in a torn-off shingle
A standard asphalt shingle is built in layers: a fiberglass mat base, saturated and coated with asphalt, then topped with mineral granules that shield the asphalt from ultraviolet light. Strip away the granules and the mat, and what is left is asphalt cement, the same binder that holds hot mix road asphalt together. That single overlap, asphalt binder in both the roof and the road, is the entire premise behind recycling shingles instead of burying them. It also explains why recyclers care about the composition of the load. A shingle is roughly a quarter to a third asphalt cement by weight, which is a meaningful amount of binder to recover instead of buying new.
02 /The pathway into road asphalt
Where shingle recycling programs exist, torn-off shingles are usually called RAS in the paving industry, short for recycled asphalt shingles, and handled the same general way as reclaimed road asphalt, RAP. A recycling facility grinds the shingles down, screens out anything that is not shingle, and blends the ground material into new hot mix asphalt at a set percentage alongside virgin binder and aggregate. The engineering behind how much RAS a mix can safely absorb is documented by transportation and asphalt pavement associations, not something we invent figures for on this page. See Michigan EGLE's recycling directory.
For a homeowner, the practical version of this is simple: a roofing tear-off does not have to be a one way trip to a landfill everywhere. Whether it is one for your project comes down to two things, covered next: what is actually in your load, and whether a facility near Macomb County accepts residential tear-off shingles at all.
03 /What keeps a load out of the recycling stream
Recycling facilities that accept tear-off shingles are protecting a finished product, hot mix asphalt that goes under traffic, so they are strict about what they take. The common disqualifiers cited in industry guidance are asbestos containing shingles, which some older roofs may have and which require special handling rather than recycling; heavy contamination with wood, nails, felt paper, or other tear-off debris; and shingles from unverified sources. A clean, single-material load is the easiest to place. A dumpster mixed with decking, gutters, and general demolition debris usually routes to a standard construction and demolition landfill instead.
This is also why recycling availability is a local question, not a universal fact. Some regions have an active shingle recycling program tied to a specific facility or hauler; others do not, and the honest answer changes depending on which processor is operating nearby in a given year. We will not name a specific southeast Michigan facility or its acceptance rules until we can point to a verified, current listing. See Michigan EGLE's recycling directory.
Do not assume your tear-off is being recycled just because a hauler mentions it, and do not assume it is going to landfill either. Ask directly: does your dumpster or hauler route shingle tear-offs to a shingle recycling processor, and does that require a separate, unmixed shingle load rather than a general demolition dumpster? The answer changes what actually goes in the dumpster on day one of the job.
04 /What this means for your tear-off
On every full roof replacement we price, tear-off and disposal is part of the job, not a surprise line item, built into the same canon range as the rest of the work: asphalt replacement runs $9,000 to $18,000, with most Macomb County homes landing $12,000 to $16,000. Whether a given tear-off routes to a recycling processor or a standard landfill depends on what is available near your address, and we will tell you honestly which one applies rather than claim a green outcome we cannot verify. To see how tear-off and disposal fit into a full project number before anyone shows up, the 60 second cost calculator and the full pricing breakdown use the same figures we quote on site.
We inspect roofs across Macomb County for free, at no cost or obligation, and if a storm is the reason your shingles are coming off ahead of schedule, our storm damage service and insurance claims guide cover what to document. The rest of our field notes, including the market forces behind decking and shingle pricing, live in the guides library. If a leak has water coming in tonight, we answer 24/7 for emergency tarping, dumpster and disposal questions can wait until morning.
