The Mercer Roofing Co Dallas Guarantee
When we finish a roof in Dallas, we don’t consider the job done until you say it’s done. The Mercer Roofing Co Dallas guarantee is simple: every repair and installation we complete is backed by our 365-Day Done Right Promise. If the work isn’t right within a year, we come back and make it right. That’s not marketing language. It’s a written commitment on every job we take. We put a written price in your hand before anything starts, and we put a written guarantee behind every repair. No fine print, no conditions buried in a contract. If our work fails, we fix it. That’s the whole promise.
Grant Whitlock, Owner at Mercer Roofing Co Dallas, built this company on a straightforward idea: a roofer should stand behind the roof they built. We’ve been doing exactly that since 2000, as part of the Threshold Group family of home-service companies.
What’s Covered
Here’s what our guarantee means when the crew pulls up to your home in Dallas:
- Workmanship. Every shingle we nail, every seam we seal, and every flashing detail we install is covered by our 365-Day Done Right Promise. If our workmanship was the problem, we’re back to fix it, free of charge.
- Parts handling. We don’t charge you for our mistakes. If we damage a component during the job, or install a part that was defective from the start, the replacement is on us.
- Cleanup. A roof job leaves nails, old shingles, and debris behind. We clean the property thoroughly before we leave, and if we missed something, call the office and we’ll send a crew back to finish the job.
- On-time arrival. When we schedule your appointment, we show up when we said we would. If something changes on our end, you hear from us before you’re left wondering where the crew is.
- Honest pricing. The written price we give you before work begins is the price you pay when the job is done. No surprise line items, no change orders that appear out of nowhere.
That’s the practical list. But the guarantee is also about trust. Every technician who steps onto your property is background-checked, identity-verified, and arrives in a clean, marked uniform with a photo ID badge. We send you their name and photo before they arrive. You know exactly who’s at your door, and that’s part of standing behind our work too.

Our Satisfaction Promise
If you’re not satisfied with the work we did, here’s what happens. First, call us at (432) 302-5605. A live person answers, 24/7. Not a voicemail, not a callback form. You’ll talk to a real human being who will listen to what’s wrong. Second, we schedule a return visit. Third, we fix the issue. If a repair fails within 365 days, we come back and make it right, free of charge. If the problem is something we caused, the fix doesn’t cost you a dime. That’s the make-it-right process, and it doesn’t require you to argue with a call center or navigate a claims department. You tell us what’s wrong, and we fix it.
We know homeowners in Dallas have been burned by contractors before. A roof is a big investment, and when something goes wrong, you want to know the company won’t disappear. We’ve been serving Dallas since 2000, and we’re part of the Threshold Group family of home-service companies. That means each location is independently owned and operated, but held to the Threshold Verified standard. There’s a framework behind the promise, and there are consequences for not living up to it. We take that seriously.
What counts as “not right”? A leak that appeared after we repaired a section. Shingles that lifted in a windstorm because they weren’t secured properly. Flashing that’s pulling away from a chimney. Decking that we replaced but is now sagging. If it’s our workmanship that failed, it’s our job to correct it. If the problem is beyond what we installed, we’ll tell you honestly what’s going on and give you a written price for the additional work. You’ll never wonder what the next step is.
More than once, we’ve had a homeowner in Dallas call us after a hail storm, worried that their new roof was damaged. We’ve gone out, inspected the roof, and told them the truth, even when the truth was that the roof held up just fine. We’d rather earn your trust than bill you for unnecessary work. That’s what “we stand behind our work” means in practice.

AfterLicensed & Insured Backing
A guarantee is only as good as the company behind it. We carry the licensing and insurance required to operate as a roofing contractor in Dallas, Texas. When our technicians are on your property, they’re working under a policy that covers them and protects you. Accidents are rare because we hire carefully, background-check everyone, and train our crews to work safely. But if something does go wrong on a job site, you’re not left holding the bill. Our insurance covers it. Our licensing means we’re accountable to the state, not just to our own conscience. That’s the real backing behind our written guarantee.
Part of being a Threshold Verified location is meeting standards that go beyond what the state requires. Every technician is identity-verified before they’re dispatched to your home. Every job is completed under the quality framework that the Threshold Group holds each independently owned location to. When you combine that with our licensed and insured status, you get a company that can actually be held accountable, not one that closes up shop when a problem arises.
If you’re researching roofers in Dallas, you’ll see plenty of promises on websites. The difference is in the paperwork. We give you a written price before work starts, and a written guarantee on every repair. We welcome questions about our licensing and insurance; a reputable company should never hesitate to show proof. Call us at (432) 302-5605 and we’ll be glad to talk through the details before you make a decision.
How the 365-Day Done Right Promise Works in Dallas
Dallas weather tests roofs year-round. We get hail in the spring, intense sun in the summer, and the occasional ice storm in winter. Your roof has to endure all of it. We design and install roofs with those conditions in mind, using manufacturer-recognized shingle brands including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. We install and repair using the materials and methods recommended by the manufacturers, because that’s how warranties hold up. When we combine proper installation with our 365-Day Done Right Promise, you’re covered from two directions: the manufacturer’s warranty on materials, and our workmanship guarantee on labor.
Here’s an example of how this plays out. A homeowner in the M Streets neighborhood of Dallas called us last spring after a storm. They’d had a section of roof repaired by another company, and water was coming through the ceiling in their sunroom. We found that the flashing around their chimney had been installed incorrectly, allowing water to run down the brick and into the house. We repaired the flashing, re-sealed the area, and replaced the damaged shingles. We gave them a written price before we started, and a written guarantee when we finished. They’ve had no leaks since, and if they do within 365 days, we’ll be back.
That’s the kind of work we want to be known for in Dallas. Not the cheapest bid, but the one that holds up. Not the fastest crew, but the one that shows up when they say they will. Not the flashiest trucks, but the technicians who badge in at the door, so you know exactly who’s working on your home.
Why We Put Everything in Writing
Verbal promises are easy to make and hard to enforce. That’s why every Mercer Roofing Co Dallas job starts with a written price, and every repair includes a written guarantee. We want you to have something you can hold onto, something that spells out what we’re responsible for. If there’s ever a question about what was promised, we can both look at the paper and see the answer. That protects you, and it protects us from misunderstandings.
The 365-Day Done Right Promise is specific. It covers 365 days from the date of the work, not some vague “we stand behind our work” phrase. Our crews don’t hide behind legal language or warranty exclusions. If the work isn’t right, we make it right. If the repair fails, the second visit is free. Those are the terms, and we’re comfortable putting them in writing because we’ve been installing and repairing roofs in Dallas since 2000. We’ve had plenty of time to get the process right.
We also back this up with the Threshold Verified standard. When you call Mercer Roofing Co Dallas, the person who answers the phone works for a company that’s contractually held to a quality framework. The technician who arrives at your door has passed a background check and identity verification. They’re in uniform, they have a photo ID badge, and their name and photo were sent to you before they pulled up. That’s not a guarantee about the shingles. It’s a guarantee about the people. And we think that’s just as important.
If you’re ready to work with a Dallas roofing company that actually stands behind what it builds, call us at (432) 302-5605. Tell us what’s going on with your roof, and we’ll give you a written price and a straightforward answer. The estimate is free, and the guarantee is real.
