Rates gathered August 25, 2026 from 4 San Antonio roofing companies' published price pages. The one-layer range is the overlap of independent local sources; the two-layer figure is an assumption and is labelled as one.
The Short Answer
Tear-off is priced per square, one hundred square feet of roof surface, on top of the new roof. One existing layer runs $100 to $300 per square in San Antonio. Against architectural shingle at $450 to $700 per square installed, removal is roughly 13% to 40% of the per-square price of the replacement, which is why an estimate that buries it inside the material line is hiding the second biggest number on the page.
What Tear-Off Adds On A 2,000 Square Foot House
A 2,000 square foot footprint at a medium pitch (6 in 12) carries about 22.4 squares of roof surface. The tear-off line on that house:
| Layers coming off | Per square | On 22.4 squares | Basis |
|---|---|---|---|
| One layer | $100 to $300 | $2,236 to $6,708 | Sourced local range |
| Two layers | $200 to $600 | $4,472 to $13,416 | Assumption: one-layer rate applied twice |
Not a sourced San Antonio rate. Set as the one-layer rate applied twice; no local source prices a second layer separately. The cost calculator carries the same assumption and flags it the same way, so ask any bidder for the two-layer line in writing.
When Can You Skip The Tear-Off?
Only when the roof has a single layer now and the new material can go over it. The City of San Antonio's re-roof permit application states that a maximum of two layers of roofing material is allowed under the International Residential Code, so a roof already on its second layer comes off in full before the new one goes on. Metal is normally installed on a single clean deck. Our permit guide covers the rest of what the application asks, and the permit itself is $25.
What Should The Tear-Off Line Say On An Estimate?
Three things: how many layers are being removed, the per-square rate, and whether the dumpster and disposal fees sit inside that line or are billed separately. A line that reads "tear-off" with a single number and no layer count cannot be checked against anything, and a crew that finds a second layer it did not price will find it on your bill. What the crew finds underneath, rotten decking or bad flashing, is priced on top and is the reason an honest quote is a range.
Metal Versus Shingle After Tear-Off
The tear-off line is the same whichever roof goes on next; the difference is the material. Our metal roof cost page runs the same 2,000 square foot house in standing seam and exposed-fastener panel, and the roof replacement cost page carries every material rate with its source.
Frequently Asked Questions
- How much does roof tear-off cost in San Antonio?
- $100 to $300 per roofing square for one existing layer, from the published price pages of San Antonio roofing companies gathered August 25, 2026. On a 2,000 square foot house at a medium pitch, about 22.4 squares, that is $2,236 to $6,708 on top of the new roof.
- How much does it cost to tear off two layers of roofing?
- No San Antonio source prices a second layer separately, so we do not have a sourced range. The calculator and this page use the one-layer rate applied twice, $200 to $600 per square, and label it an assumption. Ask a bidder for the two-layer line in writing.
- Can I put new shingles over my old roof in San Antonio?
- Only if the roof has a single layer now. The City of San Antonio's re-roof permit application states that a maximum of two layers of roofing material is allowed under the International Residential Code, so a roof already carrying two layers is torn off before anything new goes on.
- Does a metal roof need a tear-off?
- Metal is normally installed on a single clean deck, so if your roof has shingles on it now, budget the one-layer tear-off line on any metal estimate. Our metal roof cost page runs the whole-house arithmetic.
- What does a tear-off line on an estimate include?
- It should say the number of layers being removed and the per-square rate, and it should state whether the dumpster and disposal fees are inside that line or billed separately. A tear-off line with no layer count or no rate is a line you cannot check.
- Roof replacement cost per square in San Antonio
- Architectural shingle runs $450 to $700 per square installed, and a one-layer tear-off adds $100 to $300, so removal is roughly 13% to 40% of a shingle replacement's per-square price. Every material rate and its source is on the cost page.
- Do I need a permit to replace a roof in San Antonio and how much is it?
- Yes, inside the city limits, and the residential re-roof permit is a flat $25 on the City's FY2026 fee schedule. Our permit guide covers who pulls it and what the application asks.
- How much does a roof replacement cost in San Antonio?
- On the same 2,000 square foot house, architectural shingle material and labor run $10,062 to $15,652, plus $2,236 to $6,708 of one-layer tear-off and the $25 permit. The calculator runs your own footprint, pitch, material and layers.
