AfterHow Much Does Storm Damage Repair Cost in San Antonio?
Storm damage repair in San Antonio typically costs between $450 and $2,800 for most homes, with the average repair landing around $1,150. Severe hail or wind events that damage decking, underlayment, or structural components can push costs to $6,000 or more. The final number depends on what the storm actually did to your roof: shingle replacement runs lower, while flashing repair, decking replacement, and water mitigation run higher.
If you’re reading this because a storm just rolled through your neighborhood, you want numbers, not vague ranges. Here’s the straight answer: a standard hail-damage repair on a 1,800-square-foot home in San Antonio, replacing shingles on one or two slopes, runs $900 to $2,200. A full roof replacement after catastrophic storm damage runs $8,500 to $14,000 for the same size home, depending on shingle grade and decking condition. Keep reading for the full breakdown, including what drives prices up, how insurance factors in, and what you should know before you sign anything.

Storm Damage Repair Cost Breakdown (2026)
Here’s what homeowners in San Antonio are paying for storm damage repair in 2026, broken down by the type of work. These are real market ranges based on what we quote and what we see from other local roofers.
| Repair Type | Typical Cost Range | What It Includes |
|---|---|---|
| Missing shingle replacement (small area) | $450 – $900 | Replacing 10 – 20 shingles, sealing nail heads, minor adhesive work |
| Hail damage repair (one slope) | $900 – $2,200 | Replacing 100 – 250 shingles, ridge cap check, sealant on exposed fasteners |
| Wind damage repair (multiple slopes) | $1,200 – $2,800 | Shingle replacement across 2 – 3 roof faces, ridge cap replacement, flashing check |
| Flashing repair or replacement | $350 – $950 | Chimney, valley, or pipe boot flashing; includes sealant and fasteners |
| Decking repair (water-damaged section) | $600 – $1,400 | Removing damaged OSB or plywood, replacing section, re-nailing shingles |
| Underlayment replacement (partial) | $500 – $1,100 | Stripping shingles, replacing felt or synthetic underlayment, reinstalling |
| Full roof replacement (storm-damaged) | $8,500 – $14,000 | Complete tear-off, new underlayment, new shingles, flashing, disposal |
These ranges reflect what we quote in San Antonio neighborhoods like Alamo Heights, Stone Oak, Helotes, and the Northeast Side. Prices shift based on roof pitch, number of stories, and how accessible the damaged section is. A two-story home in the Dominion with a steep pitch will cost more than a single-story ranch in Leon Valley for the same square footage of repair.
What drives the price up: decking that’s soft or waterlogged, shingles that are discontinued and require color matching across the whole roof face, and code upgrades required by the City of San Antonio’s building inspection office. What drives it down: damage confined to one slope, asphalt shingles that are still in production, and a roof under 10 years old where the underlayment is still intact.

What Affects Storm Damage Repair Pricing in San Antonio
Storm damage pricing fluctuates more in San Antonio than in most Texas cities, and it’s not just about shingle prices. Here are the factors that actually move the number on your quote.
- Hail size and roof age. Hailstones smaller than one inch rarely damage a roof that’s less than five years old. But a 10-year-old roof hit by golf-ball-sized hail in the Bandera Road corridor or the Far West Side often needs a full replacement, not a patch job. Roof age is the single biggest multiplier we see.
- The type of shingle on your roof. Three-tab shingles are cheapest to replace, typically $450 to $700 for a small repair. Architectural shingles from GAF, CertainTeed, or Owens Corning run higher because the material costs more and color matching matters. If your shingle has been discontinued, expect to pay a premium for a close match or a full-face replacement.
- Roof pitch and accessibility. San Antonio has plenty of low-slope ranch homes, but subdivisions in Stone Oak and Hollywood Park often feature steep gables. Steeper pitches require more safety equipment and slower work, which adds 15 to 25 percent to labor costs. Your roofer’s safety setup should never be the place to save money.
- Decking damage from wind-driven rain. San Antonio’s storm pattern in spring and fall brings horizontal rain that gets under shingles and soaks the decking. By the time hail or wind removes the shingle layer, the OSB underneath may already be swelling. We regularly replace 4-by-8 decking sections in homes across the Northeast Side where April storms pushed water under the eaves.
- Permit requirements and code updates. The City of San Antonio requires permits for roof work that exceeds basic repair scope. If your repair triggers a re-roof classification, the inspector may require ice-and-water shield in valleys or updated drip edge. That’s a real cost, typically $200 to $500 in materials, but it’s also a code requirement you don’t want to skip.
- Time of year. Roofing demand in San Antonio spikes after major hail events, especially in April, May, and October. After a citywide storm, material lead times stretch and labor rates climb 10 to 20 percent for about four to six weeks. If your damage is minor, repairing it before the next storm season is often the cheapest route.
One thing that doesn’t affect our pricing: who’s home when we arrive. Every Mercer Roofing technician is background-checked, identity-verified, and dispatched under the Threshold Verified standard. You’ll get the technician’s name and photo sent to you before the visit, and they’ll badge in with a photo ID at your door. That’s not a pricing factor. It’s the baseline for how we operate, and Grant Whitlock holds every job to it.
Storm Damage Repair Costs by Roof Size
Roof size matters more than roof type when it comes to storm repair. Here’s a quick reference for San Antonio homes based on square footage of living space, which roughly tracks roof surface area.
- 1,200 – 1,500 sq. ft. home: Minor storm repair runs $500 to $1,200. Full replacement after severe damage runs $6,500 to $9,500.
- 1,600 – 2,200 sq. ft. home: This is the most common size in San Antonio. Minor repairs land at $700 to $1,800; full replacement lands at $8,500 to $12,500.
- 2,300 – 3,000 sq. ft. home: Repairs run $1,000 to $2,800; full replacement runs $11,000 to $16,000.
- 3,000+ sq. ft. home: In neighborhoods like the Dominion, Terrell Hills, and Olmos Park, roof systems are more complex. Repairs run $1,500 to $4,000; replacement runs $15,000 to $25,000 or more depending on shingle grade.
These numbers assume standard asphalt shingles from manufacturers we install daily: GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. Upgrading to a higher-grade shingle adds $1,200 to $3,000 on a full replacement but can improve impact resistance, which matters when the next hailstorm hits.
How Much Does Insurance Cover for Storm Damage in San Antonio?
Most San Antonio homeowner policies cover storm damage, but the deductible structure determines what you actually pay out of pocket. In Texas, many carriers now use a separate windstorm or hail deductible, typically 1 to 2 percent of your home’s insured value. On a $350,000 policy, that’s $3,500 to $7,000 out of pocket before insurance pays anything.
That’s the number homeowners miss when they’re weighing repair versus replacement. If your roof has $6,000 in hail damage and your windstorm deductible is $5,000, insurance writes you a check for $1,000. If the roof is older and the adjuster approves a full replacement at $12,000, you’re still paying the same $5,000 deductible. In that scenario, the math favors replacement, especially if your shingles are nearing the end of their service life.
Here’s the practical advice: file the claim, get the adjuster out, and get a written repair estimate from a roofer before you decide. At Mercer Roofing, we give you a written price that stands regardless of what insurance pays. You can use it to negotiate with your carrier or to decide whether the claim is even worth filing. Our estimate doesn’t change because we know what we need to charge to do the job right, and we put it in writing before you commit to anything.
We also work with your insurance timeline. If you’re waiting on an adjuster, we’ll document the damage with photos and notes so you have evidence when they arrive. That’s part of the job, not an extra charge.
When Is Storm Damage Repair Urgent?
Some storm damage can wait a week. Some can’t wait a day. Here’s how to tell the difference.
Urgent, fix now: Water entering the home through the ceiling or walls, exposed decking, missing shingles over a living space, or a tarp that’s failed. Water damage compounds fast, and what starts as a $600 repair becomes a $3,000 ceiling replacement plus mold remediation if you wait.
Can wait a few days: Hail bruising that hasn’t broken the shingle surface, small areas of lifted shingles that aren’t leaking, and cosmetic damage. Hail bruises don’t leak immediately, but they shorten the roof’s life and should be documented and repaired before the next storm season.
Needs eyes on it now, repair later: Any storm that produced hail over one inch in diameter. We recommend an inspection within a week. The damage doesn’t always show from the ground. What looks fine from your driveway can be 40 percent bruising from the roof deck.
If you’re not sure which category you’re in, call us. A live person answers at (254) 276-4369, 24/7. We’ll help you figure out whether it’s an emergency or something that can wait for an inspection. You won’t get a voicemail.
How to Save on Storm Damage Repair
Storm damage repair is never cheap, but you can avoid overpaying without cutting corners on materials or safety. Here’s what actually works.
- Get your estimate before the demand spike. After a citywide hailstorm, roofers are booked out and materials are scarce. If you can get a written estimate in the first week, you lock in pricing before labor rates climb. Our quotes hold even if material prices shift.
- Repair the damaged section, not the whole roof. If your roof is under 10 years old and the damage is confined to one slope, a targeted repair is the right call. You’ll pay $900 to $2,200 instead of $10,000. We’ll tell you honestly whether your roof qualifies for repair or needs full replacement, and we’ll put it in writing.
- Don’t wait for water damage to spread. A missing shingle is a $450 fix. A water-stained ceiling is a $1,400 fix, plus drywall and paint. The cheapest storm damage repair is the one you schedule before the water gets in.
- Check your policy before you file. If your windstorm deductible is $5,000 and the repair is $2,800, filing a claim doesn’t make financial sense, and it can raise your premium. We’ll help you read the numbers, but we won’t tell you to file or not file. That’s your call.
- Use a roofer who gives free estimates. Mercer Roofing Co San Antonio gives free estimates, always. Call (254) 276-4369 and we’ll schedule the inspection, send our technician’s name and photo before the visit, and provide a written price before any work starts. No cost to look, no pressure to sign.
And one more thing that saves money in the long run: hiring a roofer whose repair comes with a written guarantee. If the repair fails within a year, we come back and redo it free. Our 365-Day Done Right Promise means the job gets done correctly the first time, because we’re the ones paying for the second visit if it’s not.
Why San Antonio Storms Hit Roofs Harder
San Antonio sits in a weather corridor that combines two damaging forces: hail from spring supercells and wind-driven rain from late-summer and fall storms. The hail comes fast and hard in April and May. The wind comes in October and November. Both strip shingles, break seals, and expose decking.
We also see a pattern specific to certain San Antonio neighborhoods. Older subdivisions with mature trees, like Alamo Heights and Monte Vista, suffer less hail impact but more limb damage. The Far West Side and areas west of Loop 1604, where there’s less tree cover, take the full brunt of hailstorms. Homes along the I-10 corridor toward Boerne are hit by both hail and high wind because there’s nothing to slow the weather down.
What this means for repair costs: homeowners in exposed areas should expect more frequent repairs and should prioritize impact-rated shingles when it’s time to replace. A Class 4 impact-rated shingle from Owens Corning or CertainTeed can reduce hail damage significantly, and many San Antonio insurers discount premiums for it.
More importantly, it means you should know who you’re calling before the storm hits. After a major hail event, storm chasers descend on San Antonio from out of state. They knock doors, offer “free inspections,” and pressure homeowners into signing contracts. Some do decent work. Many don’t. They’re gone by the time the roof leaks again.
Mercer Roofing is different in the way that matters most: we’re part of the Threshold Group family, founded in 2000, and every location is held to the Threshold Verified standard. That means background-checked, identity-verified technicians who arrive in a clean, marked uniform with a photo ID badge. Before the visit, you’ll receive the technician’s name and photo. When they knock on your door, you’ll already know who they are. No strangers at the door, ever. That’s the Threshold Standard, and it’s the baseline for every job we take.
FAQs – Storm Damage Repair Cost
How much does storm damage repair cost in San Antonio?
Storm damage repair in San Antonio typically costs $450 to $2,800 for most homes, with an average around $1,150.

Call (254) 276-4369 for a free, written estimate specific to your roof.
Is it cheaper to repair or replace a storm-damaged roof?
For a roof under 10 years old with damage confined to one slope, repair is significantly cheaper: $900 to $2,200 versus $8,500 to $14,000 for replacement. For a roof over 15 years old with widespread hail damage, replacement often makes more financial sense, especially when your insurance deductible is high and the adjuster approves a full claim. We’ll give you both numbers in writing so you can decide with real figures, not sales pressure.
How much does hail damage repair cost in San Antonio?
Hail damage repair in San Antonio runs $900 to $2,200 for a single-slope repair on an average home, and $450 to $900 for minor shingle replacement in a small area. If hail has bruised shingles across the entire roof, you’re looking at full replacement, which ranges from $8,500 to $14,000. The size of the hail and the age of your roof are the two biggest cost factors.
Does homeowners insurance cover storm damage in San Antonio?

We’ll document the damage, provide a written estimate, and help you work through the numbers with your adjuster.
