Meet the Team - Mercer Roofing Co San Antonio

Meet the San Antonio Team Behind Mercer Roofing Co San Antonio

We’ve been roofing homes across San Antonio since 2000, and the crew we send to your door today is the reason homeowners keep calling back. Every Mercer Roofing Co San Antonio technician is background-checked, identity-verified, and shows up in a clean, marked uniform with a photo ID badge before they set foot on your property. That’s the Threshold Standard, and it’s not negotiable. What follows is the actual team you’ll meet in Alamo Heights, Stone Oak, Helotes, and everywhere in between. No subcontractors you’ve never heard of. Just our people, doing the work the way it should be done.

Our People

Luis M. – Lead Technician

Luis has been with Mercer Roofing Co San Antonio for eleven years, and there isn’t a roof style in Bexar County he hasn’t worked on. He’s our go-to for complex repair diagnostics, especially around flashing failures and valley leaks that other crews misidentify. Luis holds current manufacturer certifications from GAF and CertainTeed, which means he installs those shingle systems to the exact spec those brands require for their warranty coverage to hold. Off the clock, he coaches his son’s little league team over by McAllister Park. If you hear someone on your roof explaining the problem in plain English before any work starts, that’s Luis. He won’t touch a project until you’ve seen the written price and asked every question you have.

Dana R. – Senior Installer

Dana leads most of our full roof installations in San Antonio, which on a hot August afternoon means running a crew that knows how to pace itself without cutting corners. She specializes in steep-slope work and has put on more Owens Corning and Atlas systems than she’ll admit to. Dana is the person who catches decking rot before it becomes a structural problem, because she checks what’s underneath before she nails anything down. She’s been roofing for fifteen years, eight of them with us. On her days off, she restores a 1968 Ford pickup in her driveway, slowly. Her crews know that if the underlayment isn’t laid flat, they’re redoing it before lunch.

Marcus T. – Service Coordinator

Marcus is the voice you’ll likely hear first when you call (254) 276-4369. He’s not a call center, and he’s not a voicemail. He’s here in San Antonio, and he’s been scheduling Mercer Roofing Co San Antonio jobs for six years. Marcus knows our technicians’ schedules, which neighborhoods they’re in on a given day, and what a repair is likely to involve before we even send someone out. He walks every homeowner through what to expect: the badge at the door, the written price before work starts, the written guarantee on every repair. When a storm rolls through and phones light up, Marcus is still a live person answering, not a recording. He’s the reason our scheduling doesn’t feel like a gamble.

Elena S. – Apprentice Installer

Elena joined us two years ago after spending her first year learning the trade from the ground up, literally, starting with tear-offs and jobsite prep. She’s now installing underlayment and working alongside Dana on full roof builds across San Antonio. Elena is enrolled in our manufacturer training track, currently working toward her IKO and Tamko install credentials. What she brings to every job is simple: she shows up on time, she listens, and she doesn’t pretend to know something she doesn’t. Texans appreciate straight talk, and Elena gives it. When you see her on your property, she’ll already know your roof’s slope, your shingle type, and what the day’s heat index means for the crew’s schedule.

One Standard, Every Job

Every person above operates under the same rules, and those rules don’t change depending on the job size or the neighborhood. Our technicians are background-checked and identity-verified before they ever knock on a San Antonio door. You get their name and photo before they arrive, and you can check that photo against the badge they present when you open the door. That’s Threshold Verified, the standard set by the Threshold Group family of home-service companies and applied at every independently owned location. It means if the work isn’t done right within 365 days, Mercer makes it right. It means every repair carries a written guarantee, with a free second visit if the repair fails. And it means the written price you approve before work starts is the price you pay, no change orders, no surprises on the invoice. The crew in Alamo Heights is held to the exact same bar as the crew in Stone Oak, because they’re often the same people. Grant Whitlock, our owner, put it plainly when he built this team: the badge matters, but the work behind it matters more.
