AfterShingle Replacement in San Antonio, TX
Shingle replacement in San Antonio typically runs $350 to $900 for a smaller repair area of 8 to 12 shingles, and $4,200 to $9,500 for a full roof replacement on an average 1,800-square-foot home. We finish most repair-level shingle jobs in a single visit, and you’ll know the full price in writing before we climb the ladder. If you’re looking at curling tabs, missing shingles, or a patch that’s been leaking, call Mercer Roofing Co San Antonio at (254) 276-4369 for a free estimate. We’re part of the home services family of Threshold Group companies and we handle shingle work as a core piece of our Roof Repair in San Antonio offering.
Shingle replacement means removing cracked, wind-torn, impact-damaged, or granule-worn shingles and installing new ones that match your roof’s profile and color. Sometimes that’s a Roof Repair job of a dozen shingles. Sometimes it’s the whole roof. Either way, the work has to be right because San Antonio’s weather swings hard: intense summer sun, downbursts in spring, and the occasional hailstorm in March or April that can chew through cheap asphalt in fifteen minutes.
What sets Mercer Roofing Co San Antonio apart on this specific repair: the person coming to your house is someone you know before they ring the bell. When you book with us, you receive the technician’s name and photo ahead of the visit. On arrival, that technician presents a photo ID badge and arrives in a clean, marked uniform. That standard is called the Threshold Verified badge standard, and every Mercer location is contractually held to it. No wondering who’s at your door. No trusting a voice on the phone. We put it in writing: every shingle job includes a written price before work starts and a written 365-Day Done Right Promise on the repair itself.
When You Need Shingle Replacement
You don’t always need a whole new roof when shingles show wear. But ignoring the symptoms below in San Antonio’s climate usually turns a few hundred dollars of shingle work into Valley Repair, decking, and insulation damage. Here’s what we see across neighborhoods like Alamo Heights, Stone Oak, Helotes, and Leon Valley:
- Curling or lifted shingle tabs – Shingle edges that visibly turn upward or cup in the middle have lost adhesion. That’s a wind-lift risk. On homes near Loop 1604 with more open exposure, those lifted tabs catch strong gusts and tear off.
- Missing shingles after a storm – San Antonio’s spring storms produce straight-line winds that can peel shingles off in minutes. The longer the felt underlayment stays exposed to our sun, the faster it degrades.
- Granule loss in gutters – If you clean the gutters and find a pile of gray-black grit, your shingles are shedding their protective ceramic coating. That’s UV exposure damage and it accelerates fast here where June and July roof surface temps exceed 150°F.
- A persistent ceiling stain or attic drip – A small leak doesn’t announce itself dramatically. Often it’s a single shingle that cracked at a nail line, or a section of flashing worn through. Replacing the damaged shingles and the seal around penetrations stops the leak before it ruins decking below.
- Hail impact marks – After a hail event, we find circular impact craters in shingle surfaces. A homeowner often can’t spot them from the ground. Hail damage that removes granules exposes the asphalt substrate and shortens the shingle’s life by years. We inspect and give you a straight answer on what must be replaced and what can wait.
- Shingles at the end of their service life – Most standard three-tab asphalt shingles last about 18 to 22 years in our climate. Architectural shingles from brands like GAF and CertainTeed can go 25 to 30 years. But our sun is punishing, and a 20-year-old roof that’s shedding granules and showing curled tabs is usually a candidate for at least partial replacement.
If you see any of these signs, call (254) 276-4369. A live person answers, day or night. We’ll schedule an inspection and give you a written price for the work, no pressure and no obligation.
Our Shingle Replacement Process
Every shingle replacement we do in San Antonio follows a clear sequence. You’ll know what’s happening at each step, and you’ll have it in writing before any work starts. Here’s how we do it:
- Inspection and diagnosis. We examine the roof surface, the underlayment condition, the decking from the attic side where accessible, and any flashing around chimneys, vents, and skylights. We identify whether this is a repair-scope job or a full replacement, and we tell you why in plain English.
- Written price before any work starts. We don’t give verbal ballparks and then change the number. You’ll get a written price that includes the shingle materials, labor, any decking repair we anticipate, and cleanup. Nothing is conditional. This is the Mercer Roofing Co San Antonio standard on every job.
- Technician introduction and identity verification. Before the scheduled work day, you’ll receive the name and photo of the technician coming to your home. When they arrive, they present a photo ID badge at the door and wear a clean, marked Mercer uniform. The same applies to every visit under the Threshold Verified standard.
- Shingle removal and surface preparation. We remove the damaged or worn shingles and inspect what’s under them. If we find soft decking or damaged underlayment, we flag it immediately and show you what we found. We fix the underlying issue before installing new shingles, because new shingles over bad decking is a guaranteed re-leak.
- New shingle installation with manufacturer-matched materials. We work with shingle brands including GAF, CertainTeed, Owens Corning, and Boral, and we match color and profile to the existing roof where possible. New shingles are installed to the manufacturer’s nail pattern and wind-rating spec, with proper sealing.
- Cleanup and final walkthrough. We magnet-sweep for nails, remove old shingle debris, and do a final roof inspection. Before we leave, you’ll have the 365-Day Done Right Promise in writing for the work just completed.
For most repair-scope shingle jobs, the whole process happens in one day. Full replacements typically take 2 to 4 days depending on roof size, pitch, and weather. San Antonio’s spring rain can shift schedules, so we’ll keep you posted if that happens.
Shingle Replacement Pricing in San Antonio
What you’ll pay depends on scope: patching a few shingles versus replacing a whole slope or the entire roof. Material type matters too. Architectural shingles from CertainTeed or GAF run higher than basic three-tab, but they hold up better in hail and our sun. Here’s a realistic range for the San Antonio market based on the job types we quote most often:
| Job Type | Price Range | Typical Timeline |
|---|---|---|
| Replacing 5 – 8 shingles (small patch) | $350 – $600 | Same day |
| Replacing 12 – 20 shingles (storm damage section) | $600 – $1,100 | Same day |
| Single roof slope replacement (up to 500 sq ft) | $1,800 – $3,400 | 1 – 2 days |
| Full roof shingle replacement (average 1,800 sq ft home) | $4,200 – $9,500 | 2 – 4 days |
These ranges reflect San Antonio’s market for quality shingle work as of 2026. Factors that push a job toward the higher end: steep roof pitch requiring additional safety rigging, multiple layers of old shingles that must be torn off, rotten decking sections discovered beneath the shingles, Flashing Repair needs, and premium shingle brands like Boral or CertainTeed’s high-wind lines. You’ll never get a surprise change order from us. The written price covers what we said it covers, and if we find something underneath that must be addressed, we show you before we touch it.
Call (254) 276-4369 and a live person will take your call. We’ll schedule a free on-site estimate and give you the written number. No high-pressure closing. No “today only” discounts. Just a real price from a company that’s been doing this work since 2000 as part of the Threshold Group family.
FAQs – Shingle Replacement
Is it cheaper to repair or replace shingles in San Antonio?
For damage confined to a small area, repairing is almost always cheaper: $350 to $1,100 versus $4,200 to $9,500 for a full replacement. But if your roof is past 20 years old or the damage is widespread, replacement prevents repeated repair bills. We’ll give you a straight answer when we inspect, not a sales pitch. Call (254) 276-4369 for a free estimate.
Can you replace shingles the same day in San Antonio?
Yes, for repair-scope jobs of up to about 20 shingles, we can usually complete the work the same day we inspect. Availability depends on current scheduling and weather. Spring storms in San Antonio create high demand, so call (254) 276-4369 early if you have exposed underlayment, an active leak, or need Vent Boot Repair.
How much does it cost to replace a few missing shingles in San Antonio?
Most small shingle patches in San Antonio run from $350 to $600, depending on the location of the damage on the roof and how many shingles are missing. Steep pitches that require safety harnesses add some labor cost. You’ll have the exact written price before any work begins.
Do you match shingle colors on partial replacements?
Yes, we match the existing shingle brand and color as closely as the manufacturer’s current product line allows. If the original shingles are discontinued, we’ll show you the closest available match before we order materials. For roofs under 10 years old, a color-matched partial replacement usually blends well. For roofs over 15 years old, sun fading can make an exact match difficult. We’ll be honest about what the finished look will be before you commit. Call (254) 276-4369 and we’ll inspect the roof and give you options.
