Fast, Reliable Roof Repair Across Terrell Hills
Roof repair in Terrell Hills typically costs between $450 and $2,800 depending on the scope, with most small leak and shingle fixes landing in the $450 – $900 range. We dispatch crews from our San Antonio office to Terrell Hills throughout the week, and our live team answers the phone 24/7 at (254) 276-4369. If your roof is leaking after a hail storm or you’re staring at cracked clay barrel tiles on a 1930s estate, call us for a written quote before any work begins.
Terrell Hills is not a generic roofing market. The homes here – grand Spanish Colonial and Mediterranean Revival estates from the 1920s through the 1940s, plus solid mid-century ranches – carry roof systems that demand a different level of care than a typical subdivision track home. We know the difference between a skip-sheathed 1938 tile roof and a 1965 composition shingle ranch, and we price and plan the work accordingly.
Why Mercer Roofing Co San Antonio Is Terrell Hills’s Preferred Roof Repair Company
Terrell Hills homeowners call us because we send the technician’s name and photo before they arrive, and that technician badged in with a photo ID at the door. That matters here. Many of our customers in Terrell Hills are home alone during the day, have young children, or are older and want proof of who is standing on their porch. Every Mercer technician is background-checked, identity-verified, and dispatched under the Threshold Verified standard, which each location is contractually held to.
Our Roof Repair team has handled everything from hail-cracked clay tile on Cambridge Oval estates to wind-lifted shingles on ranch homes near the Terrell Hills city hall. Founded in 2000, Mercer Roofing is part of the Threshold Group family of home-service companies. Every job comes with a written price before work starts, and every repair includes a 365-Day Done Right Promise in writing.
What that promise means in practice: if the repair fails within a year, we come back at no charge. Not a pro-rated warranty, not a callback from a different crew. A free second visit to make it right. Terrell Hills homeowners who have been burned by fly-by-night storm chasers tell us that single sentence is why they called us.
Styles & brands we work with






Shingle Roof Repair in Terrell Hills
Shingle Roof Repair in Terrell Hills usually runs $450 – $1,400 for a typical repair, depending on how many shingles were lost, whether the underlayment is torn, and what the decking underneath looks like once we lift the damaged area. The mid-century ranch homes along streets like Garraty Road and Eldon Road mostly carry composition shingle roofs, and after a hail event we often see missing granules, lifted tabs, and impact bruising that doesn’t leak immediately but fails within months.
What Shingle Repair Includes
A proper shingle repair starts with removing the damaged shingles and checking the underlayment beneath. On Terrell Hills ranches built before 1970, we sometimes find the original felt is cracked or the fasteners have backed out. We replace what’s compromised, install new shingles matched to the existing color and profile, and seal the repair. You get a written guarantee on the work, not a verbal promise.
When a Terrell Hills Homeowner Needs It
Call us when you see shingles in the yard after a storm, granules collecting in the gutters, or a water stain on the ceiling that wasn’t there last week. Waiting is expensive. A loose shingle lets water into the decking, and by the time the stain shows up, the rot has likely spread. The faster call is the cheaper one.
Storm Damage Roof Repair in Terrell Hills
Storm Damage Roof Repair in Terrell Hills typically costs $600 – $2,800, with the higher end covering multiple roof faces, valley flashing replacement, and decking repair after severe hail or wind. Terrell Hills sits in South Central Texas hail country. When a storm rolls through, the damage isn’t just missing shingles – it’s dented flashing, cracked tile, and underlayment tears that let water in sideways, behind the fascia, where it hides for months.
Hail and Wind Damage Assessment
We inspect every plane of the roof, the valleys, the flashings, the boots, and the areas behind fascia and soffit. On a 1930s Mediterranean estate near the Terrell Hills city hall, our crew replaced hail-cracked clay barrel tiles by sourcing matching originals from a local salvage yard and hand-forming custom ridgelines. We upgraded the underlayment to a high-temp peel-and-stick and reset the copper flashing at every valley and penetration to meet the city’s strict wind-load and aesthetic review, finishing with a documented wind-rating certificate for the homeowner’s insurance file.
Documentation for Insurance Claims
When you file a hail claim, the insurer sends an adjuster who looks for documented damage. We provide a written repair scope, photos, and where applicable, a wind-rating certificate that shows the work meets local code. Terrell Hills homeowners tell us this documentation has made the difference between a denied claim and a paid one. A cheap repair that skips this paperwork saves a few hundred dollars on the front end and often costs ten times that in a disputed claim.
Trusted Brands We Service in Terrell Hills
We stock and install Owens Corning, IKO, and Atlas shingles for Terrell Hills roofs, and we match existing roofs regardless of what’s currently on them. If your 1990s ranch has a discontinued color, we can source a close match from our supplier network or recommend a re-feed that won’t look patchy. Parts and materials for the common Terrell Hills roof types – composition shingle, flat membrane, and clay tile repairs – are readily available through our San Antonio supply chain, so turnaround is measured in days, not weeks. We never list a brand we don’t actually stock, and we’ll tell you plainly what’s on your roof and what it will take to fix it.

AfterCommon Roof Repair Problems We See in Terrell Hills Homes
- Failed decking under original tile roofs. Terrell Hills’ pre-1950 estates often have skip sheathing – spaced boards, not solid plywood – that cannot hold modern fasteners or support new underlayment. When a tile cracks and water gets in, the sheathing rots unnoticed until a storm pulls a whole section off. This is a structural repair, not a patch job.
- Missing ice and water shield at eaves and valleys. Cheap repair bids leave out the peel-and-stick membrane that Terrell Hills’ code requires at the edges. Hail events here drive water sideways and uphill, and without that membrane, water gets behind fascia and soffit and shows up months later as mold inside the wall cavity.
- Non-matching architectural shingles on tile roofs. Terrell Hills’ aesthetic ordinance requires replacements to match the original tile profiles on 1920s – 1940s estates. A contractor who slaps a mismatched architectural shingle over a tile repair is creating a code violation. The city can issue a stop-work order and require removal at the homeowner’s expense.
- Discontinued clay barrel tiles. Many Terrell Hills roofs were built with custom clay barrel tiles that are no longer manufactured. Repairing them means sourcing matching tiles from salvage yards or fabricating custom replacements. This is not a garden-variety shingle patch – it’s a preservation project, and it costs accordingly.

FAQs About Roof Repair in Terrell Hills
A roof repair in Terrell Hills must meet the wind-load requirements in the city’s adopted building code, which for most re-roof and significant repair work means materials rated for high-wind exposure. Verification comes through the inspection: the inspector checks fastener pattern, underlayment type, and edge metal. We document every repair with photos and, for larger jobs, a wind-rating certificate that lists what standard the work met. That certificate is the document your insurance company wants to see after a hail claim. Call (254) 276-4369 and we’ll explain what your specific roof needs.
Yes, in most cases. We source matching original tiles from salvage yards that carry the specific profiles used on Terrell Hills estate homes from that period. When a custom match isn’t available, we fabricate replacement tiles to match the original profile and color. The repair includes resetting the surrounding tiles, replacing the underlying membrane, and verifying the whole assembly meets the city’s aesthetic and wind standards. This work is more expensive than a shingle patch – typically $1,000 – $2,800 – but it preserves the roof you have instead of forcing a premature full replacement. Call us for an exact quote; estimates are free.
Terrell Hills requires a permit for roof repair that goes beyond a simple shingle or tile replacement – anything involving decking, structural members, or more than a small repair area. The inspection covers the underlayment, fastener pattern, flashing details, and materials being used. Aesthetic compliance is part of it too: the inspector checks that replacement materials match the original profile, especially on the 1920s – 1940s estates. We pull the permit, schedule the inspection, and you get the passed-inspection record with your job file. That record is part of what protects your insurance claim later. Call (254) 276-4369 with questions about your specific roof.
Insurance adjusters evaluate hail claims against the documentation you can produce. Without it, your claim is a he-said-she-said between you and the insurer. With it – photos, a written repair scope, the permit record, the wind-rating certificate – your claim has a paper trail an adjuster can verify. Terrell Hills homeowners who skipped documentation on a cheap repair often find their next hail claim denied or reduced because the insurer can’t confirm prior work met code. We build the documentation package into every repair we do. It costs you nothing extra and it’s worth real money when the next storm hits.
A cheap bid omits three things a compliant Terrell Hills repair must include: the ice and water shield at eaves and valleys, the code-required wind-rated fastening, and the permit and inspection record. It also often omits aesthetic matching on tile roofs, which the city enforces. None of those omissions will show up on day one – they surface when the next hail storm finds the path left open, or when the city catches the mismatch and issues a stop-work order. The compliant quote includes those items in writing, line by line, before any work starts. Ours does. Call (254) 276-4369 for a free estimate and see the difference on paper.
