Why Mercer Roofing Co San Antonio Is Schertz’s Preferred Roofing Company
Homeowners in Schertz tell us the same thing over and over: they want to know who is walking up the driveway before they open the door. That is exactly how we operate. Every technician who arrives at your Schertz home is background-checked, identity-verified, and uniformed. Before the visit, we send you the technician’s name and photo. At the door, they present a photo ID badge. That is the Threshold Verified standard, and every Mercer location is contractually held to it.
We are part of the Threshold Group family, founded in 2000. Each location is independently owned and operated, but the vetting standard does not change. Schertz customers get the same written price before any work starts, the same 365-Day Done Right Promise, and the same live-person phone answer at 2 a.m. that they get in any city we serve. Grant Whitlock leads our team, and he holds every job to the standard that keeps Schertz homeowners calling us back for roof repairs, replacements, and inspections.
Local knowledge matters here. Schertz sits in the hail-prone I-35 corridor, and storms roll through often enough that our crews know exactly what adjusters look for after a claim. We photograph damage per square, measure the affected area, and document granule loss before the adjuster ever arrives. That is the kind of detail that gets claims approved at full value, and it is the reason Schertz homeowners recommend us to their neighbors.

Roof Inspection in Schertz
Roof Inspection in Schertz should happen at least once a year, and right after any storm that drops hail or throws wind-driven debris across I-35. In Schertz, hail storms are frequent enough that neighborhoods like Fairhaven show blue tarps on roofs within days of a storm. A thorough inspection catches the damage early – granule loss, cracked shingles, dented flashing, soft decking – before it becomes a leak inside your home. Most residential roof inspections in Schertz run $150 to $350, depending on roof size, slope, and accessibility. If you have a claim, we document everything and help you file it.
After-Storm Hail Documentation
This is not a glance from the driveway. We walk the full roof, photograph every square of damage, test for soft decking, and check flashing, drip edge, and ridge vents. We measure the affected area in squares – the roofing term for 100 square feet – so your insurance adjuster gets a clear, professional report. Schertz homeowners who skip this step often get under-compensated because the damage was never properly documented.
Pre-Purchase Roof Inspections
Buying a home in Schertz? Many of the 1970s-1990s homes in this area still have original composition shingles. A pre-purchase roof inspection tells you how many years are left, whether decking rot is present, and what a replacement would cost before you sign. We provide a written report with photos and honest numbers, not a sales pitch.
Commercial Roofing in Schertz
Commercial Roofing in Schertz covers low-slope and flat systems on retail, office, and multi-family buildings along the I-35 corridor and throughout the older commercial districts. Schertz has grown fast, and with that growth comes a mix of aging commercial buildings with original flat roofs and newer structures that need maintenance to keep warranties intact. Commercial roof repairs in Schertz typically run $500 to $1,800 for localized fixes like flashing failures, membrane punctures, and drain issues. Full replacement costs depend on the system, but most flat roof replacements in the Schertz market run $6 to $12 per square foot.
Flat Roof Maintenance and Repair
Flat roofs fail quietly. Water ponds, seams separate, and leaks find their way into tenant spaces before anyone notices. We inspect drains, check membrane seams, and repair flashing around rooftop units. Our techs document everything and give you a written price before work starts, every time.
Insurance Claims for Commercial Buildings
Commercial claims in Schertz need the same hail documentation as residential ones, often with more square footage and more complex roof systems. We photograph the damage, measure it in squares, and provide the report your adjuster needs. That documentation is the difference between a partial payout and a full replacement.
Trusted Brands We Service in Schertz
We install and repair the brands Schertz homeowners and commercial property managers know, and we offer Schertz Gaf service alongside Owens Corning and CertainTeed. When you need a repair on an existing roof, we stock common shingle colors and accessory parts locally so you are not waiting on a special order from out of state. If your Schertz home has an older GAF Timberline or a CertainTeed Landmark roof, we can match it for a clean repair. For replacements, we help you choose the brand and grade that fits your budget and the hail exposure your Schertz roof faces every spring and summer.

AfterCommon Roofing Company Problems We See in Schertz Homes
- Hidden decking rot found only at tear-off. In Schertz homes from the 1980s and 1990s, water intrusion often goes unnoticed under shingles until a reroof starts. We write inspection findings and replacement allowances into the contract upfront, so you are never surprised by a change order after tear-off.
- Reused flashing on a post-hail reroof. Some contractors leave old drip edge and flashing in place to save time. That fails early and voids manufacturer wind warranties. We replace all metal on every reroof, every time.
- Under-documented hail damage. Without photos and per-square measurements, adjusters underpay. We document everything before you file, so the claim reflects the real damage to your Schertz roof.
- Blue-tarp limbo after a storm. After a heavy hail event, roofing crews get stretched thin across the I-35 corridor. We respond quickly, install a temporary tarp when needed, and get your repair or replacement scheduled without leaving you waiting for weeks.

FAQs About Roofing Company in Schertz
Look for granule loss in your gutters, dents in metal flashing or vents, cracked shingles, and soft spots when you walk the roof. In Schertz, hail often leaves a pattern of circular cracks or bruising across entire roof slopes. If neighbors in your area are getting new roofs after a storm, you likely have qualifying damage. We document everything per square before you call your adjuster. Call (254) 276-4369 for a free inspection.
Older Schertz homes often need ice and water shield in valleys, improved decking attachment, and sometimes drip edge that meets current code. If the decking is damaged or the roof structure was built before modern wind-load standards, the city may require upgrades. We include those in the written estimate before work starts, not as a surprise later.
Fairhaven has many homes built in the 1980s and 1990s with original composition shingles that are now near the end of their service life. Hail hits those older, brittle shingles harder. Newer subdivisions have younger roofs with shingles that absorb impact better. That is why we stay busy in Fairhaven after every storm.
A square is 100 square feet of roof area. Most Schertz single-family homes run between 20 and 35 squares. When we quote your replacement, the number of squares, the shingle grade, and the amount of decking replacement determine the price. We break all of that out in writing. Call (254) 276-4369 for a free estimate.
Schertz sits in a high-wind corridor along I-35, so we use a six-nail pattern on architectural shingles rather than the four-nail minimum some contractors get away with. That extra fastening is what keeps shingles on your roof during the severe thunderstorms that roll through every spring. It also keeps your manufacturer wind warranty valid.
If you need a Roofing Company team that documents damage, prices in writing, and sends a background-checked tech with a photo ID to your Schertz door, call (254) 276-4369 today for a free estimate.
