How Mercer Roofing Co Austin Was Born in Austin
We didn’t name this company. Mercer Roofing was already doing roofs done once and done right long before we hung our sign in Austin, and that’s exactly why we brought it here. The brand carried a reputation we wanted to stand behind, a way of working that felt overdue in this market.
What struck us when we opened this branch was how many Austin homeowners were exhausted by the same routine. A crew shows up, no one knows who they are, the quote comes on a handshake, and three months later a Texas thunderstorm finds the weak spot. We had watched too many people in neighborhoods like Wells Branch and Hornsby Bend get burned by work that looked fine from the street and failed at the first real test.
So when we opened the Austin location, we didn’t have to invent a promise. We had to keep one. Every technician badged at the door. A photo and a name sent before anyone rings the bell. A written price before any work starts. Those aren’t marketing lines to us. They’re the reason we get to sleep at night, and the reason a homeowner can finally stop guessing who’s on their roof.
Grant Whitlock took the lead here knowing that Austin deserved a roofing crew that didn’t just talk about respect, but proved it at the front door.
Grant Whitlock’s Personal Connection to the Roofing Trade
Grant got into this work the way a lot of people do: by standing on a roof one afternoon and realizing the person up there mattered. Early on, he worked alongside a tradesman who had been doing roofing for decades, and what stuck with him wasn’t just the technique. It was the smell of hot shingles in July, the sound of a nail gun echoing off a chimney, the way a properly sealed valley felt under your hand when you ran your fingers across it. That man taught him that a roof is a series of small decisions you either do right or you don’t, and the only person who knows the difference is the one laying the shingle.
What kept Grant in the trade was the moment after the job. Standing in the driveway with a homeowner while they looked up at their roof, not sure what they were supposed to be looking at. That’s the part corporate roofing gets wrong. They hand over an invoice and drive off. Grant wanted to be the person who pointed out the ridge cap, explained why the flashing was cut the way it was, and told them what to watch for during the next spring storm. That conversation is the job. It always was.
He’s been at this for more than two decades, and what gets him out of bed hasn’t changed. It’s the homeowner who opens the door with a toddler on their hip and a worried look, because they’ve never hired a roofer before and every headline tells them not to trust the knock at the door. If he weren’t doing this, he’d probably be teaching a trade class somewhere, trying to convince young people that working with your hands and your word is still a noble way to make a living.
But he’s still climbing ladders, and he doesn’t plan to stop. The work feels personal because it is. A roof is the one part of a house a family never thinks about until it fails, and in Austin, between the hail and the hundred-degree heat, it fails a lot. Grant wants to be the calm voice on the other end of that first phone call.
Meet Grant Whitlock – The Person Behind Every Job
Grant Whitlock is the Owner & Founder of the Austin location of Mercer Roofing. He leads the local team here, bringing years of hands-on trade experience to the work itself and a plain-spoken honesty to the way we run the business. His background is in the field first: roofing, inspecting, problem-solving, and learning what happens to a roof in Texas weather when the details get skipped.
What separates Grant from a franchise technician is simple. He lives here. When a customer in Cedar Park asks about hail damage from a storm in March, he knows which storm they’re talking about because he got caught in it too. He’s not reading a script. He’s remembering his own roof.
Off the ladder, Grant is the kind of person who keeps a small notebook in his truck and writes down anything he wants to double-check back at the shop. Not because he doesn’t trust his memory, but because he doesn’t trust anyone who thinks they’re too good to write it down. That’s the man you’ll get. Not a sales pitch. A roofer who listens, writes it down, and does what he said.
His commitment to the customer is this: if he wouldn’t put the roof on his own house the way the quote says, he won’t put it on yours. Simple as that.
Our Promise to Austin Homeowners
We work to a standard called The Threshold Standard, and it shapes everything. Background-check and identity-verify every technician. Send the tech’s name and photo before the visit. Show a photo ID badge at the door, every time. Arrive in a clean, marked uniform. Put the price in writing before any work starts.
Those aren’t best-case intentions. They’re the floor. If anyone arrives at your door who you were not told to expect, that visit is on us and we make it right. That promise matters more to us than any clever slogan, because opening your door to a stranger is a genuine worry for many people. It should be. We built our way of working around that.
Our Credentials
- State-licensed – every pro working under our name is required to hold the license their state requires.
- Insured and bonded – every pro working under our name is required to carry the insurance their state requires.

Why does this matter when you’re hiring a roofer? Because licensing and insurance protect you from liability and shoddy work.

They’re the minimum of what you should expect when someone works above your family’s heads.
Rooted in Austin
We work across Austin and the surrounding communities: Cedar Park, San Marcos, Brushy Creek, Hutto, Lakeway, Bastrop, Lago Vista, Lost Creek, Hornsby Bend, Shady Hollow, and Wells Branch. Each one has its own weather patterns, its own architecture, its own way of wearing a roof down over time. We know the difference between a roof in Lakeway that bakes in the afternoon sun and a roof in Bastrop that gets hit with wind shear off open land.
Austin is a city that respects straight talk and hard work, and that’s what we try to bring to every job. We don’t pretend to be from every town. We’re a local independent business that agreed to work to a higher standard, and we’re proud to do it right here.
