Fast, Reliable Roof Installation Across Terrell Hills
A new roof on a Terrell Hills home typically runs between $14,000 and $42,000 depending on material, pitch, and whether we’re dealing with the city’s own permitting requirements or simpler county rules on an outbuilding. That’s the honest range we quote, and it’s backed by a written price before any work starts. Mercer Roofing Co San Antonio has installed and repaired roofs across Terrell Hills long enough to know that a Spanish Colonial estate off Garraty Road is a different job than a mid-century ranch near the Terrell Hills Country Club. You’ll get a real person on the phone at (254) 276-4369, and a technician whose name and photo arrive before we do.
Why Mercer Roofing Co San Antonio Is Terrell Hills’s Preferred Roof Installation Company
Terrell Hills homeowners call us for a simple reason: we don’t send a stranger to your door. Every technician who arrives is background-checked, identity-verified, and wearing a marked uniform with a photo ID badge. That’s the Threshold Verified standard we’re held to as part of the Threshold Group family, founded in 2000. You’ll know who’s coming before they ring the bell.
Local knowledge matters here. Terrell Hills is its own municipality with its own code enforcement, and we’ve worked through enough city inspections to know what gets flagged. A roof that clears county review on a detached shop can still fail in Terrell Hills if the tile profile doesn’t match the home’s original character. We check both sets of rules before we quote, so you don’t get surprised mid-project. Grant Whitlock, who leads our crews, has seen too many homeowners forced into a tear-off because someone skipped that step.
Our 365-Day Done Right Promise applies to every installation. If the work isn’t right within a year, we make it right. Written guarantee included, no fine print games.
Styles & brands we work with






Standing Seam Metal Roof in Terrell Hills
A standing seam metal roof in Terrell Hills runs $18,000 to $38,000 on a typical estate home, and it’s one of the smartest choices for this climate. South Central Texas throws large hail and high winds at roofs year after year, and standing seam panels shrug off both better than most materials. The vertical seams also shed water fast, which matters on the low-slope sections you sometimes see on mid-century ranch houses here.
Hail and Wind Resistance
Terrell Hills sits in a hail corridor that has totaled asphalt roofs all over Bexar County. Standing seam metal carries Class 4 impact resistance ratings when paired with the right underlayment. For a 1940s estate with mature oaks shedding branches in windstorms, that’s not an upgrade. It’s the sensible default.
Long Haul Logistics and Open Lots
Panels come in long runs, which means material handling on a Terrell Hills acreage lot takes planning. We stage panels away from septic drain fields and well setbacks, and we protect gravel or dirt driveways with matting when the haul is long. Every quote includes that staging plan in writing.
Tile Roof in Terrell Hills
A tile roof in Terrell Hills runs $24,000 to $48,000, and if your home is one of the grand Spanish Colonial or Mediterranean Revival estates this city is known for, you may not have a choice about keeping tile. The city’s aesthetic standards and historic overlays often require it. We install and repair tile roofs that match what’s already there, including discontinued profiles.
Matching Discontinued Clay Barrel Tile
The hardest part of tile work in Terrell Hills isn’t the installation. It’s finding tile that doesn’t exist anymore. Many of these homes were roofed in the 1920s through 1940s with clay barrel tiles that haven’t been manufactured in decades. We source matching salvage tiles from regional yards, and when salvage doesn’t turn up enough, we fabricate custom replacements to match the original coursing and color. On a 1940s estate off Garraty Road, our crew replaced a discontinued clay barrel tile roof where several valleys had failed and water was tracking into the attic. We sourced matching salvage tiles, installed new decking, ice and water shield in the valleys, and copper flashing at the penetrations, then set the replacement tiles to the old coursing so the new roof is indistinguishable from the original.
Ridge Detailing and City Review
Terrell Hills code enforcement looks at ridge details. A flat concrete tile substitution that flattens the roof’s profile won’t pass review on a protected home, and it shortens the home’s long-term value besides. We spec ridge caps, hips, and rakes to match the original drawing, and we pull the city permit ourselves.
Trusted Brands We Service in Terrell Hills
We install and repair roofs using manufacturer-recognized brands including Owens Corning, IKO, Atlas, and Tamko, and we keep a local stock of the accessories these systems need. That means flashing, ridge caps, underlayment, and venting don’t get delayed waiting on a distributor three counties away. For Terrell Hills homeowners, that’s the difference between a roof that’s weather-tight before the next storm front and one that’s still tarped. Call (254) 276-4369 and we’ll walk you through which brand fits your roofline and budget.

AfterCommon Roof Installation Problems We See in Terrell Hills Homes
- Double permitting, double standards. A county-permitted roof on an outbuilding or detached ADU gets installed without checking Terrell Hills’ own historic overlay or architectural review, forcing a tear-off after the fact. We check both before we quote.
- Discontinued tile assumptions. Contractors tell homeowners the original clay barrel tile can’t be matched, so they substitute a flat concrete tile that changes the home’s character. We source salvage and fabricate custom replacements instead.
- Septic and drain field damage. Long material hauls and a tight lot with mature oaks leave debris or staging in the septic drain field, compacting the soil and creating drainage problems that show up after the roof is finished. We map the drain field and setbacks before the first pallet lands.
- Underlayment shortcuts on tile roofs. Old tile roofs often fail at the underlayment, not the tile itself. A cheap tear-off that reuses old felt will leak inside three years on a Terrell Hills estate. We always replace decking and underlayment to current code.

FAQs About Roof Installation in Terrell Hills
Yes. Terrell Hills is its own municipality with its own permitting and code enforcement, and a roof on a detached shop or ADU can clear county rules and still fail city inspection if the tile profile, ridge detailing, or material doesn’t match the city’s architectural standards. We check both the county approval and the city’s review requirements before we quote, so there’s no tear-off surprise. Call (254) 276-4369 for a free estimate that accounts for both.
We keep all material staging and equipment at least 25 feet from any septic drain field and 50 feet from a well head, and we map both before the first pallet lands. Compacting a drain field with stacked shingles or a parked material trailer can create drainage problems that outlast the roof itself. We write the staging plan into your quote, so you know where everything sits before we start.
Yes. We source matching salvage tiles from regional yards, and when salvage doesn’t turn up enough coverage, we fabricate custom replacements to match the original coursing and color. We’ve done this on estates off Garraty Road where the original tile hasn’t been made in decades. The new roof ends up visually identical to the original, and it passes Terrell Hills’ own architectural review. Call (254) 276-4369 for an exact quote on your tile profile.
Yes. The intersection where an attached shop or ADU roof meets the main roofline needs stepped flashing and often a custom saddle or cricket, especially on the varied eaves and parapets common to Spanish Colonial and Mediterranean Revival homes in Terrell Hills. Get that detail wrong and water tracks into both structures at the transition. We scope the flashing plan before we quote, in writing.
We lay protective matting over gravel and dirt driveways before any heavy truck or material trailer rolls in, and we schedule deliveries to minimize the number of trips over the same wheel ruts. Long hauls on an acreage lot don’t have to chew up your drive. The matting plan and delivery schedule are part of your written quote. Call (254) 276-4369 to schedule your free estimate.
