How Mercer Roofing Co Dallas Was Born in Dallas
When we opened our doors in Dallas back in 2000, the roofing trade here had a reputation problem. Homeowners told us story after story about crews that showed up late, left debris in the yard, and handed over a final bill that looked nothing like the original quote. One homeowner in the M Streets showed us a contract from a previous roofer with a number crossed out in pen and a new number scribbled next to it, no explanation, no call, just a bigger invoice. That was the moment we knew Dallas deserved better.
So we built our local branch around a simple idea: the Threshold Standard. Every technician background-checked and identity-verified. Every tech’s name and photo sent to you before they ring the bell. A photo ID badge shown at the door, every time. A clean, marked uniform. And a written price before any work starts. Not as a slogan, but as a daily habit. No crossed-out numbers. No mystery invoices. Just roofing done once and done right.
Grant Whitlock’s Personal Connection to the Roofing Trade
Grant Whitlock didn’t grow up dreaming about shingles. He grew up watching his father climb ladders to patch leaks and replace flashing on their own house in East Dallas, the kind of house where a roof repair meant the difference between a dry winter and a ruined ceiling. His father wasn’t a roofer by trade, just a man who believed you fixed things yourself, and he passed that stubbornness down. Grant remembers the smell of hot tar on a July afternoon, the weight of a bundle of shingles on his shoulder, the sound of a nail gun echoing off the neighbor’s brick wall. Those Saturdays taught him something that stuck: a roof is the first line of defense a family has, and the person who works on it had better care.
He carried that with him into the trade. Before leading this branch, Grant spent years on roofs across North Texas, learning the difference between a roof that’s slapped on and a roof that’s installed to hold. He’s worked through hailstorms in Plano, repaired wind damage in Grand Prairie, and walked more ridge lines than he can count. What keeps him in it, after all these years, is the same thing that got him started: the look on a homeowner’s face when they hear a straight answer, see a line-item price, and know exactly who’s climbing onto their roof. That trust isn’t abstract to him. It’s personal.
If he weren’t in roofing, Grant says he’d probably be teaching shop class somewhere, showing kids how to measure twice and cut once. But he’s here instead, running the branch he was meant to run, in the city he’s always called home.
Meet Grant Whitlock – The Person Behind Every Job
Grant Whitlock is the Owner & Founder of Mercer Roofing Co Dallas. He leads a team that works to the Threshold Standard, but he’s not a guy who sits in an office while someone else handles the ladder work. He’s the one who walks the job site with you, explains what he sees in plain words, and makes sure the crew knows exactly what was promised.
Off the clock, Grant restores old furniture in his garage. It’s slow, careful work, the kind you can’t rush, and he says it reminds him of roofing in the best way: if you respect the materials and do the job right the first time, the thing lasts. That’s the same patience he brings to every roof he touches.
Here’s what Grant wants you to know: when you hire us, you’re hiring him. He stands behind every job, every nail, every shingle. That’s not a marketing line. That’s how he’s run this branch since day one.
Our Promise to Dallas Homeowners
Three promises, no fine print.
Honest pricing. The price we put in writing before the work starts is the price you pay. No crossed-out numbers, no surprise line items at the end. If the scope changes, we talk about it first, in plain words, and you approve it before anything moves.
Quality parts. We work with proven roofing materials like IKO, Atlas, and Tamko because a roof is only as good as what’s under it. We don’t cut corners on underlayment, flashing, or fasteners, and we don’t pretend a cheap patch is a real fix.
Standing behind every job. If something’s wrong, we come back and make it right. We don’t disappear after the check clears. That’s what it means to badge in at the door and do the job once.
Our Credentials
- State-licensed. Our branch operates under the roofing license the state of Texas requires.
- Insured & bonded. Every pro working under our name is required to hold the insurance their state requires, so your property is protected while we work.
- More than two decades serving Dallas and the surrounding cities. We’ve been here since the branch opened in 2000, and we’re not going anywhere.
- Strong local reputation. Homeowners across Dallas, Richardson, Duncanville, and beyond keep calling us back and referring their neighbors.
Why does this matter to you? Because the person on your roof is a stranger until they prove otherwise. A license means they’ve met the state’s baseline. Insurance means an accident won’t become your financial problem. Years in the local market mean they’ve seen what North Texas weather does to a roof and they know how to fix it. That’s the peace of mind you’re paying for.
Rooted in Dallas
We work in Dallas because we live here. Our crews know the difference between a hail-damaged ridge in Plano and storm wear in Grand Prairie. We know the older homes in Lakewood and the newer builds in Murphy. We drive these streets, shop these stores, and sit in the same traffic on I-30. This isn’t a territory to us. It’s home, and we roof it like our own families live under every deck.
