AfterHow Much Does Roof Replacement Cost in San Antonio?
Roof replacement in San Antonio typically costs between $8,500 and $18,000 for a standard single-family home, with most homeowners paying around $12,500 for an architectural shingle roof in 2026. That figure is based on an average 1,800 to 2,200 square foot roof. Your actual cost will shift depending on square footage, shingle choice, roof pitch, and whether the decking underneath needs to be replaced.
At Mercer Roofing Co San Antonio, every price is written down before any work begins. You will know the exact number before a single nail is driven, and that number will not change unless we find hidden damage and get your sign-off first.

Roof Replacement Cost Breakdown (2026)
Here is what a roof replacement in San Antonio looks like line by line, based on what we see across Alamo Heights, Stone Oak, Terrell Hills, and the older neighborhoods around Monte Vista and Jefferson.
| Cost Component | Typical Range (San Antonio, 2026) | Notes |
|---|---|---|
| Tear-off and disposal | $1,800 – $3,200 | Removing existing shingles and hauling to landfill. Older homes with multiple layers cost more. |
| Decking repair / replacement | $600 – $2,400 | Replacing rotted or warped plywood or OSB. Common after hail and heavy Hill Country storms. |
| Underlayment | $700 – $1,400 | Synthetic or felt barrier between decking and shingles. Synthetic costs a bit more but performs better in humid San Antonio summers. |
| Shingles (materials only) | $2,800 – $7,500 | Three-tab asphalt is cheapest. Architectural shingles from GAF, CertainTeed, or Owens Corning run more. Premium options like Atlas or Boral cost the most. |
| Flashing and vents | $400 – $900 | Metal flashing around chimneys, skylights, and valleys, plus ridge and soffit venting. |
| Labor | $2,500 – $4,500 | Installation crew costs. Steeper pitches and complex layouts add labor, not material cost. |
| Permits | $50 – $250 | San Antonio requires a re-roof permit. Some municipalities in Bexar County differ. |
| Total | $8,500 – $18,000 | Most jobs fall between $10,000 and $14,000. |
The gap between $8,500 and $18,000 is real, and it is driven by choices: a simple ranch house with three-tab shingles on a low-pitch roof sits at the bottom of that range. A two-story home in Stone Oak with architectural shingles, a steep pitch, and 200 square feet of rotted decking sits at the top.
Note that insurance is a separate conversation. If your roof was damaged in a San Antonio hailstorm, your policy may cover part or all of the cost, and we are happy to document everything for your adjuster. But the numbers above are what a cash repair or replacement actually costs in this market today.
What Affects Roof Replacement Pricing in San Antonio
- Roof size. The single biggest lever. San Antonio homes range from 900-square-foot bungalows in Government Hill to 4,000-square-foot builds in Dominion. More squares of roofing mean more material and more labor.
- Shingle type. Three-tab asphalt runs $3.50 to $4.50 per square foot installed. Architectural shingles run $4.50 to $5.50. Specialty brands like Boral and premium Atlas lines run $6.00 to $6.50. It is tempting to go cheap, but San Antonio’s July sun and occasional hail argue for at least a mid-grade architectural product.
- Roof pitch. Anything over a 6/12 pitch means the crew moves slower and uses more safety equipment. Steep roofs are hard work, and that shows up in labor cost.
- Decking condition. Homes built in the 1960s and 70s in neighborhoods like Jefferson and Woodlawn Lake often have decking that has been baked through years of San Antonio heat. Hail hits, then water gets in, then plywood swells and rots. Replacing 8 to 10 sheets of decking is not rare, and it adds anywhere from $600 to $2,400 to the job.
- Tear-off vs. overlay. Code in San Antonio generally allows a re-roof over one existing layer in some circumstances, but most homeowners and most good contractors strip to the deck. The tear-off adds cost, but it also shows you exactly what is under your shingles before it becomes a problem.
- Chimneys, skylights, and valleys. Every protrusion needs flashing. Every valley needs special treatment. The more complex the roofline, the more hands-on time the crew needs, and that adds $400 to $1,500 depending on the house.
How Much Does Roof Replacement Cost by Material in San Antonio?
Material choice is the biggest decision inside your control. Here is what each product tier actually costs per square foot installed in the San Antonio market in 2026.
Asphalt Shingles
Cost: $3.50 – $5.50 per square foot installed.
Three-tab is the budget option, but we rarely recommend it for San Antonio. The wind and hail here are hard on thin shingles. Architectural shingles from GAF, CertainTeed, Owens Corning, or Tamko are the sweet spot: more durable, better warranties, and only a modest price bump over three-tab. Our Roof Replacement in San Antonio page has more detail on architectural options.
Metal Roofing
Cost: $7.00 – $12.00 per square foot installed.
Metal handles San Antonio sun better than anything else, and it shrugs off hail that would dent a car door. Standing seam is the premium choice; exposed-fastener metal panel is the more affordable option.
Clay and Concrete Tile
Cost: $9.00 – $16.00 per square foot installed.
Tile is a South Texas look, common in the Spanish-style homes around Alamo Heights and Terrell Hills. It is heavy, which means the roof structure sometimes needs reinforcement, and that material is beautiful but unforgiving underfoot. If a tile roof leaks, the tile itself often hides the entry point. Repairs on tile take longer and cost more.
Slate
Cost: $14.00 – $25.00 per square foot installed.
Rare in San Antonio, but occasionally requested for historic homes. Slate is a lifetime roof, but the structure underneath has to support the weight. Most San Antonio homes are not built for it without structural work.
How to Save on Roof Replacement
Saving on a roof does not mean cutting the wrong corners. It means making choices that reduce cost without reducing protection. Here is what actually works in San Antonio.
- Get your roof inspected in spring or fall. Roofers are slammed after spring hailstorms and after the first big summer heat wave. Scheduling in March or October means more availability and sometimes better pricing. That said, if your roof is damaged, do not wait. A small leak today is a decking replacement in six months.
- Consider a re-roof when you have realistic time. Emergency tear-offs cost more. If your roof is at 20 years but still functioning, plan the replacement while you can compare materials and bids calmly. Rushed jobs almost always cost more.
- Ask your insurance company about hail coverage. San Antonio sits in what insurers call Hail Alley. If a storm hit your area in the last 12 to 18 months, call your adjuster. Many homeowners leave real money on the table because they assume the damage was not “that bad.” In neighborhoods like Cibolo and Schertz, we regularly find hail damage that homeowners never noticed.
- Choose a company that gives a written price before work starts. No surprises is not just a slogan. At Mercer Roofing, the price we put in writing is the price you pay. That protects you from the “it was worse than we thought” invoice that shows up after the tear-off. Call (254) 276-4369 to get a written estimate before you commit to anything.
- Do not pay for warranty hype. A “lifetime limited warranty” from a shingle manufacturer covers materials, not labor. Read the fine print. The labor warranty is the one that matters, because labor is where most failures come from. Ours is simple: the 365-Day Done Right Promise means if it is not done right within a year, we make it right. In writing.
- Use the roof’s natural lifespan. If you have a 25-year architectural shingle roof and it is at year 17, you do not need a full replacement unless there is damage. A targeted repair costs less. Our home page details how we approach those decisions without upselling you into work you do not need.
Frequently Asked Questions
How much does a roof replacement cost in San Antonio in 2026?
Most San Antonio homes pay between $8,500 and $18,000 for a full roof replacement, with architectural shingles costing about $12,500 on a 2,000-square-foot roof. Three-tab shingles bring the low end down around $8,500, while premium materials like metal and tile push the high end above $20,000 on larger homes. Every Mercer Roofing project starts with a written, fixed price before any work begins, so the number you agree to is the number you will pay. Call (254) 276-4369 for a free estimate tailored to your roof.
Is it cheaper to repair or replace a roof in San Antonio?
If your roof has isolated damage, like a single storm-damaged section or a leak around flashing, a repair typically costs $350 to $1,200, which is far cheaper than replacement. But if your shingles are past 18 to 20 years old and you have recurring leaks, replacing the full roof at $8,500 to $18,000 is usually the better financial call, because patching an aging roof repeatedly adds up fast. Come to the decision with real numbers: request a written estimate, and do not let anyone push you toward a full replacement without seeing the condition of your existing roof and decking for yourself.
How long does a roof replacement take in San Antonio?
Most standard San Antonio residential roof replacements take one to three days, with single-story homes on low-pitch roofs often finished in a single day. Larger homes, steep roofs, tile or metal installations, and jobs requiring decking replacement can stretch to four or five days. Weather plays a role too, and San Antonio’s spring storm season can push schedules around. We will give you a delivery date before work starts, and your price will not change if rain delays the job.
Does insurance cover roof replacement in San Antonio?
Homeowners insurance typically covers roof replacement when the damage is sudden and accidental, like hail, wind, or a fallen tree. The amount covered depends on your policy, your deductible, and whether you have actual cash value or replacement cost coverage. If hail hit your neighborhood in the last year, even a few months ago, it is worth filing a claim, because damage often shows up slowly. We can document the exact condition of your roof for your adjuster, and our written estimate helps you know what the job should cost before you negotiate with your insurer.
What does a roof replacement cost per square foot in San Antonio?
Roof replacement in San Antonio runs $3.50 to $6.50 per square foot installed in 2026, with most architectural shingle jobs landing around $4.50 to $5.50 per square foot. That includes tear-off, underlayment, shingles, flashing, and labor. Use that range as a quick gut check when you get a quote: a 2,000-square-foot roof should land between $9,000 and $13,000 for architectural shingles. Anything quoted far outside that range deserves a second look.
Why San Antonio Roofs Age Differently
San Antonio is not Houston, and it is not Dallas. The climate here does specific, predictable things to roofs, and those things affect your replacement cost and your material choices.
First, the sun. San Antonio gets roughly 300 days of sunshine per year, and a dark asphalt shingle on a summer afternoon can reach 150 degrees. That heat bakes shingles from the outside in, breaking down the oils that keep them flexible. A roof in Alamo Heights at year 15 often looks like a roof in Seattle at year 25. The heat is also relentless on the decking, which can turn brittle and dry long before the shingles above it show visible damage.
Second, hail. Bexar County sits in a hail corridor that runs from the Hill Country down toward the coast. Spring storms can drop golf-ball-sized hail across neighborhoods like Helotes, Leon Valley, and Shavano Park, and the damage is rarely visible from the ground. A roof can look fine from the curb and have thousands of dollars of bruising underneath, which is another reason to get a professional inspection after any significant storm, even if the shingles are still in place.
Third, humidity. San Antonio’s humidity spikes in May and September, and that moisture plus the heat creates the perfect environment for algae and moss on roofs that sit in shade. Algae streaks are mostly cosmetic, but the humidity also accelerates the rusting of flashing, especially around chimneys and skylights, and rusted flashing is one of the most common leak sources we see in older San Antonio homes.
All of this shapes how we price and plan a replacement. When Mercer Roofing inspects a San Antonio roof, we are looking for heat fatigue, hail bruising, and flashing rot, because that is what this market actually produces.
What Makes Mercer Roofing Different in San Antonio
Most homeowners do not replace a roof more than once or twice in their lives, so the process is unfamiliar. That is not an excuse for a roofing company to make it opaque. Here is what we do differently, and it is all in writing before anything starts.
Every Mercer Roofing technician is background-checked and identity-verified under the Threshold Verified standard, which is a quality framework held by the Threshold Group, founded in 2000. That means the person who comes to your home is the person we told you was coming. Before they arrive, you get their name and photo. When they knock on your door in Stone Oak, Alamo Ranch, or Timberwood Park, they are in a clean, marked uniform, and they carry a photo ID badge that they will show you at the door. That is not a security camera gimmick. That is the most concrete thing a roofing company can do to earn your trust before the first nail goes in.
We also put our workmanship guarantee in plain English. It is called the 365-Day Done Right Promise, and it covers every repair we do. If something is not right within a full year, we come back and make it right. No fine-print exceptions, no pro-rating. And if a repair fails, the second visit is free. That is a promise we have kept since the company was founded in 2000, under the leadership of Grant Whitlock.
We install and repair shingles from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so your material choice is not limited by what we happen to have in the warehouse. The written price comes before any work starts, and it is not conditional. It is not an estimate that drifts. It is the number.
If you call (254) 276-4369, a live person answers. Not a voicemail, not a call-back form, not an automated menu. Day or night. If your roof is actively leaking at 2 a.m. after a spring storm, you will talk to a human being who can start the process right then. That matters more than any coupon.
How the Process Works: From First Call to Finished Roof
Replacing a roof is a project with a defined sequence. Here is exactly how it goes with Mercer Roofing, so you know what to expect at every step.
- You call. A live person answers at (254) 276-4369 and sets up a time for a roof inspection. We will ask about your home’s age, any recent storm damage, and whether you have noticed leaks or missing shingles.
- We inspect. A Mercer technician visits your home at the scheduled time. You will receive their name and photo before they arrive, and they will show you a photo ID at the door. The inspection covers shingles, flashing, decking, vents, and attic ventilation, and it is free.
- You get a written price. We provide a documented, line-item proposal that shows exactly what will be done, what materials will be used, and what the total cost will be. The price on that paper is the price you will pay, whether the job takes one day or five.
- We schedule the work. Once you approve the written price, we set a date. Most San Antonio replacements are completed in one to three days.
- The crew arrives. The work happens on the date we agreed to. Your property is protected with tarps, and materials are placed with care. The crew wears uniforms and works with respect for your home and your neighborhood.
- We inspect the work, again. After the roof is finished, we do our own walk-through, checking seams, flashing, cleanup, and overall quality against our standard. If anything is off, we fix it before we call the job done. And if something surfaces within 365 days, the Done Right Promise means we are back out to make it right.
That is the process. It is the same whether you are in Alamo Heights on a 1950s bungalow or in a new build near Landera. You should never wonder who is coming to your home, what they are doing, or what it will cost. You should have answers to all three in writing before the work starts.
Ready to Know Your Exact Replacement Cost?
Every roof is different, and the right way to get a real number is to have a professional look at your roof, your decking, and your attic ventilation in person. A ballpark range is useful for budgeting, but you need a written price before you can make a confident decision.
Call Mercer Roofing Co San Antonio at (254) 276-4369 for a free roof inspection and a written replacement estimate. A live person answers, 24/7, and before your technician arrives, you will have their name and photo. You will see their badge at the door. You will get your price in writing. And if we do the work, the 365-Day Done Right Promise stands behind every repair and every roof we install.
No pressure. Just a straight answer about your roof and what it will cost to fix it.
