Why Mercer Roofing Is Floresville’s Preferred Roof Repair Company
Floresville homeowners tell us the same thing: they want to know who is walking up the driveway before the doorbell rings. So we send every technician’s name and photo ahead of the visit. When the door opens, the person on the other side is in a clean, marked uniform with a photo ID badge and the Threshold Verified standard behind them. That matters on quiet streets near the Wilson County Courthouse and in the newer subdivisions off FM 536, where a stranger at the door is a real concern.
We are part of the Threshold Group family, founded in 2000. Each location is independently owned and operated, and every technician is background-checked and identity-verified before they ever set foot on a Floresville roof. Our Roof Repair team also works with manufacturer-recognized brands including Owens Corning, Atlas, and IKO. Grant Whitlock leads our crews, and he holds every job to the same standard: written price first, written guarantee always.
Storm Damage Roof Repair in Floresville
Storm Damage Roof Repair in Floresville means dealing with what South Texas thunderstorms leave behind: golf-ball-sized hail, straight-line winds, and shingles scattered across the lawn. Floresville sits in a hail-prone corridor, and spring and early summer storms roll through fast. After a big one, we see clusters of damage claims from the same neighborhoods. Most storm repair jobs run $500 – $1,200 for spot shingle replacement or flashing that got torn loose, while a full storm replacement on an average single-story home runs $6,000 – $12,000.
Hail Damage Assessment and Repairs
Hail bruising is not always visible from the ground. We check for granule loss, soft spots in the shingle mat, and cracked seals. On newer Floresville homes with architectural shingles, we can often replace individual damaged shingles. On older downtown homes with 15-to-20-year-old roofs, the math shifts: the whole roof may need replacing, and impact-resistant shingles make sense for the next hailstorm.
Wind-Lifted Shingle Re-Securing
Straight-line winds lift shingle tabs and break the sealant strip. That lets water creep under the shingle and into the decking. We re-secure lifted tabs, replace broken ones, and check the entire slope for seal failure, because a wind-damaged roof underperforms for the rest of its life if the seals are not restored.
Metal Roof Repair in Floresville
Metal Roof Repair in Floresville usually means fixing screw-backed panel roofs that have loosened over time, or older standing-seam and corrugated metal on farmhouses and converted buildings. Metal roofs are common on older Floresville homes and agricultural structures outside downtown. We see rusted panel seams, backed-out screws with failed rubber washers, and hail dents that crack the panel coating. Typical metal roof repair runs $450 – $1,400 depending on panel type and the extent of seam or fastener work.
Fastener and Seam Repair
Backed-out screws are the most common metal roof failure we see in Floresville. Each screw has a small rubber washer that hardens and cracks after years of South Texas sun. We replace the failed fasteners with new ones and re-seal seams with a metal-rated sealant. This is a same-day job on most single-story panels.
Hail-Dented Panel Replacement
Hail does not just dent metal, it breaks the protective coating and starts rust. On an older metal roof near the courthouse, we often replace individual panels rather than the whole roof, as long as the panel profile is still made. If it is not, we quote a full re-panel or a transition to a metal-like architectural shingle.
Trusted Brands We Service in Floresville
We install and repair Owens Corning, Atlas, and IKO roofing systems, along with other manufacturer-recognized brands. For Floresville customers, that means we can typically match your existing shingle when a spot repair is possible, and we can bring the right underlayment, flashing, and ridge cap on the first trip. Stocking common parts for South Texas homes means less waiting and fewer return trips. If you are upgrading after hail, we will walk you through impact-resistant options from Owens Corning and Atlas so you know what your insurance premium may reward.

AfterCommon Roof Repair Problems We See in Floresville Homes
- Hail-bruised shingles on 15-to-20-year-old subdivision homes. The roofs on newer Floresville edges were installed in the mid-2000s build-out, and many are now at the end of their design life. Hail is the trigger, but age is the underlying problem.
- Flashing failures around chimneys and valleys. South Texas temperature swings expand and contract metal flashing, breaking the sealant. Water gets in at the corners, and by the time you see the ceiling stain, the decking has been wet for weeks.
- Vent boot dry rot on steep-pitched older roofs. The rubber boot around a plumbing vent cracks after ten to fifteen years of sun exposure. On an 8/12 pitch, the leak runs down the roof deck and pools at the nearest seam.
- Wood-shingle deterioration on historic downtown homes. Late-1800s cedar shingles curl, split, and lose their weatherproofing. When one area fails, matching the aged cedar is nearly impossible, so a full replacement is often the only durable fix.

A full tear-off and replacement on a typical single-story Floresville home runs $6,000 – $12,000 depending on square footage, pitch, and whether the property is in the downtown historic district and needs review.

FAQs About Roof Repair in Floresville
No, Floresville generally does not require a permit for a minor shingle replacement or small flashing fix that does not alter the roof structure. Permit review applies to full replacements and any work in the downtown historic district, particularly when visible roof materials change. We check the specific block and property before we quote, and we handle the paperwork if a review is needed. Call (254) 276-4369 with your street address and we will tell you what your property needs.
On a tight downtown lot, we typically park the dump trailer curbside with a daily permit and stage materials in the driveway, not on the street or the neighbor’s side. On our Third Street job, we ran all tear-off down a debris chute into a trailer parked at the curb, with a daily permit. We will never block an alley or a neighbor’s access, because that gets a code complaint before the first shingle comes off. The parking plan is part of the written quote.
No, and we will not pretend otherwise. Aged 1890s cedar shingles have a color, thickness, and weathering pattern that new wood shingles cannot match. A spot repair on those roofs looks like a patch and often fails within a year because the new shingles do not seat against the curled, aged ones. On the Third Street job near the courthouse, we laid plywood over the existing wood shingles and installed a full GAF architectural shingle system with ice and water shield in the valleys. That is the durable fix, and we will quote the full replacement instead of selling you a patch that will telegraph under the steep pitch.
Yes, and we do it for you. Any time we work on a shared wall, party line, or a flashing detail that touches a neighbor’s side, we notify the neighbor in writing before we start. Downtown Floresville has old homes built close together, and a flashing repair on one roof can affect the drainage of the one next door. The notice includes our contact information and the work window, so your neighbor is not surprised when a crew arrives. It keeps the job clean and avoids disputes.
Floresville’s residential work-hour restrictions generally limit construction noise to daytime hours on weekdays, with limited or no work on Sundays in some districts. We schedule roof work between 7 a.m. and 6 p.m. on weekdays and keep Saturday work to lower-noise tasks like inspection and light repair. Full tear-offs with tear-off chutes and nail guns happen on weekdays. When we quote your job, we tell you the planned work window and respect the noise limits for your specific street.
