Fast, Reliable Roof Repair Across Cibolo
Roof repair in Cibolo usually falls into two buckets right now: hail damage from spring storms and heat fatigue from summers that regularly push past 100°F. Most calls we get from Deer Creek, Turning Stone, and Buffalo Crossing involve missing shingles, leaking valleys, or flashing that has pulled away from the roofline. If you have water coming in or shingles in the yard, call us at (254) 276-4369. We send a background-checked, photo-badged technician to diagnose the problem, and you get a written price before any work starts.
Our Roof Repair team knows Cibolo’s housing stock well. These 2000s-era tract homes have steep roof planes and multiple valleys, which means repairs here often take more flashing and underlayment per square than older houses in Schertz or Selma. That is not a markup. It is the reality of how these homes were built. We account for it up front so your quote is honest the first time.
Why Mercer Roofing Co San Antonio Is Cibolo’s Preferred Roof Repair Company
Since 2000, Mercer Roofing has built its reputation on something most roofing companies never mention: who exactly is walking up to your door. Every technician dispatched into Cibolo is background-checked, identity-verified, and uniformed under the Threshold Verified standard. Before the visit, we send you the technician’s name and photo. When they arrive, they present a photo ID badge. If someone shows up claiming to be from Mercer and cannot show that badge, do not let them on your property. That is a concrete difference, not a slogan.
We have repaired roofs on nearly every street pattern in Cibolo, from the cul-de-sacs off Bolton Road to the newer subdivisions along Green Valley Road. Our crews are dispatched from the San Antonio office, but they work Cibolo jobs weekly. That means we do not need to “figure out” local wind codes or the quirks of Cibolo’s 2000s-era decking. We already know them. Every repair includes our 365-Day Done Right Promise in writing: if the repair fails within a year, we come back and make it right at no charge.
Calls are answered by a live person 24/7. Not a voicemail tree. Not a call-back form. A human being. When you are staring at a water stain spreading across your ceiling at 9 p.m., that matters.
Styles & brands we work with






Emergency Roof Repair in Cibolo
Emergency Roof Repair in Cibolo typically means one of three things: a tree limb has punctured the decking during a thunderstorm, hail has torn through shingles and exposed the underlayment, or wind has peeled back a section of roof and rain is actively entering the home. In these situations, the priority is stopping the water. We tarp the damaged area, document everything with date-stamped photos, and provide a written scope of work before the tarps come off. Emergency tarping in Cibolo generally runs $350 – $600, and the full repair after that depends on what is underneath.
Storm Response Across Cibolo Neighborhoods
When hail hits Deer Creek or Turning Stone, our crews are usually on the ground within 24 hours. We know those neighborhoods get flooded with out-of-town storm chasers the morning after a storm. That is why we document pre-existing condition carefully. If your roof had hail damage before the storm, your insurance adjuster needs to see that distinction clearly.
What We Check Before Tarping
Before we tarp any Cibolo roof, we inspect the decking, underlayment, and flashing around every penetration. Emergency repairs that skip this step often fail within weeks. Cracked decking under a tarp still flexes and leaks. You would be surprised how often we find storm chaser repairs from the previous season that already need redoing.
Flat Roof Repair in Cibolo
Flat Roof Repair in Cibolo is less common than shingle work, but we see it on patio covers, garage additions, and a handful of mid-century homes near Old Cibolo. The main enemies here are ponding water and UV degradation. Cibolo’s summer heat bakes the membrane, and when the membrane develops hairline cracks, water pools and finds its way through. A typical flat roof patch in Cibolo runs $450 – $900 depending on the size of the damaged area and whether the underlying insulation board has rotted. If the whole section needs resurfacing, you are looking at $2,800 – $5,500 for a typical residential garage cover.
Membrane Repairs and Seam Reinforcing
Most flat roof leaks happen at seams, around vents, or where the membrane meets a vertical wall. We clean the area, strip back the failed material, and install new flashing with a reinforced patch that extends well beyond the damaged zone. This is not a quick-fix tar smear. We install it to last through Cibolo’s next storm season.
When a Patch Is Not Enough
If your flat roof has multiple soft spots or the membrane has pulled away from the edges, a patch will fail. We will tell you that in writing. Sometimes the honest answer is a full re-cover instead of repeated $400 patches that add up fast. You get that recommendation with a fixed written price before any work begins.
Trusted Brands We Service in Cibolo
We repair and install shingles from manufacturers that have proven themselves in South Central Texas weather: Owens Corning, IKO, and Atlas. Each makes products rated for high wind and impact resistance, which matters in Cibolo when spring hail season arrives. We keep common underlayment, flashing, and shingle colors stocked for quick turnaround on smaller repairs. If your roof has a specific color from one of these brands, we can usually match it without ordering and waiting a week.

AfterCommon Roof Repair Problems We See in Cibolo Homes
- Wind-voided nailing patterns on steep roofs. Cibolo’s 2000s-era homes often have shingles that were never nailed to proper spec. During a thunderstorm, the wind gets under the shingle tabs and peels them off in sheets. The repair is not just replacing shingles; it is re-nailing the entire affected plane to meet wind-load requirements.
- Hail-damaged valleys and flashing. Deer Creek and Turning Stone take direct hits during spring storms, and the first places to fail are the valleys and step flashing. Hail dents the metal, water works its way under the shingles, and leaks show up months later.
- Heat-fatigued shingles with granule loss. Cibolo summers push asphalt shingles hard. Granules wash into the gutters, the shingle surface becomes brittle, and cracking starts at the edges. The repair often includes adding attic ventilation so the next shingle layer does not bake as fast.
- Failed pipe boot seals at penetrations. The rubber boots around plumbing vents crack after a few years of Cibolo heat. When we replace them, we inspect the underlayment under the boot too. Skipping that gets you a leak that comes back every six months.
Pricing for Roof Repair in Cibolo, TX
Here is what actual repairs cost in Cibolo, based on jobs we have done across the city:
- Shingle replacement (small area): $325 – $650
- Leak repair at a valley or flashing point: $400 – $850
- Vent boot replacement: $275 – $450
- Flashing repair around a chimney or sidewall: $500 – $1,100
- Flat roof patch: $450 – $900
- Ice and water shield installation (per valley): $150 – $300
What changes the price in Cibolo is the roof geometry. Steep planes with multiple valleys require more flashing, more ice and water shield, and more labor hours. A quote that looks cheap on a 4-valley Cibolo home often leaves out the underlayment work that is required by local wind-load standards. Our written quotes include everything. You will never get a change order for “extra flashing we did not anticipate.” Call (254) 276-4369 for a free estimate with line-item pricing.

FAQs About Roof Repair in Cibolo
Most residential shingle repairs in Cibolo do not require a separate wind load certification, but any roof assembly work must comply with the city’s adopted building code, which specifies wind speeds for the region. When we replace shingles, we nail to the manufacturer’s high-wind pattern and document the installation. If your insurance carrier asks for evidence of compliance, our photos and scope documentation support the claim. Call (254) 276-4369 and we will tell you exactly what your specific repair will need.
Date-stamped photos of your roof before and after a storm create a clear record of what the hail actually damaged versus what was already worn. Insurance adjusters in Cibolo see a lot of claims after storms hit Deer Creek and Turning Stone. If you can show the pre-storm condition, the claim moves faster and disputes are less likely. We include this documentation on every storm repair.
Cibolo homes with multiple valleys and long eaves need ice and water shield in those valleys because water volume during a South Central Texas thunderstorm can overwhelm standard underlayment. The shield is a self-sealing membrane that prevents leaks where water concentrates. Some roofers quote without it to look cheaper. We include it because it is required for a lasting repair on these complex rooflines.
Yes, and you should. A roofing square is 100 square feet. Most Cibolo repairs are under two squares. The problem is that two quotes for one square can differ by $400 or more because one leaves out underlayment, flashing, or ice and water shield. Ask every roofer to break the quote down by square, by material, and by line item. Our quotes are already structured that way. Call (254) 276-4369 for a written, itemized estimate.
Cibolo sits in a region where the adopted code requires roof assemblies to withstand high wind events, and most of our repairs are nailed to a 130 mph wind rating. That is the manufacturer specification for high-wind installation on shingles like GAF Timberline HDZ. If a roofer cannot tell you what wind rating their nailing pattern meets, get a different roofer. Last spring, our crew repaired a hail-damaged architectural shingle roof in Deer Creek where the storm chasers had missed cracked decking and failing underlayment near a valley. We replaced the decking, installed ice and water shield, new drip edge, and GAF Timberline HDZ shingles nailed to 130 mph spec, then documented the pre-existing condition with date-stamped photos before filing the insurance claim.
