The Mercer Roofing Co Austin Guarantee
We put it in writing before we pick up a hammer. Every roof repair and installation we do in Austin comes with a written price you approve first, and a written guarantee you keep after we leave. If the work isn’t right within 365 days, we come back and make it right. No fine print, no “we’ll see what we can do.” That’s our 365-Day Done Right Promise, and it’s the same promise we’ve operated under since Mercer Roofing Co Austin was founded in 2000. A roof is a big purchase, and you shouldn’t have to cross your fingers after the crew drives away.
What’s Covered
- Workmanship, for 365 days. If a repair or installation fails within a year because of how we did the work, we fix it at no charge. A free second visit is included with every repair, automatically.
- Written pricing before any work starts. You’ll see the full scope and cost in writing before we begin, and that’s the price on the invoice. No change orders slipped in, no surprise line items.
- Manufacturer-recognized materials. We install and repair GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral shingles, so your roof carries the backing of the people who make the materials.
- Clean, careful work sites. Our technicians are background-checked, identity-verified, and arrive in clean, marked uniforms with photo ID badges. They treat your home like a workplace, not a parking lot.
- A live person on the phone. Calls to Mercer Roofing Co Austin are answered by a real human being, 24/7. You’ll never reach a voicemail when you need to talk about your roof.
- Honest communication. Before the technician arrives, you get their name and photo sent to you. You’ll know who’s coming to your door before they ring the bell.

Our Satisfaction Promise
Here’s how it works if something isn’t right. You call us at (361) 202-8874, a live person answers, and we schedule a return visit. We don’t ask you to prove your case or fill out a form. We send a technician back to look at the work. If the issue falls within the 365-day window and traces back to our workmanship, we repair it. That’s the promise Grant Whitlock, owner of Mercer Roofing Co Austin, makes on every job, and it’s why the guarantee is written and not spoken. The goal is simple: when we finish a roof in neighborhoods across Austin, from Hyde Park to Circle C, the homeowner should never have to think about that roof again. If you do have to think about it, we want to hear about it the same day you notice it, not after a year of watching a stain grow.
Licensed & Insured Backing
Paperwork matters because a guarantee only works if the company behind it is still standing. Mercer Roofing Co Austin is licensed and insured, and we carry the coverage to back up our promises. Being insured and bonded means if something goes wrong on a job site, you’re not left holding the bill. Being licensed means the people on your roof know Austin’s building codes and permit requirements. Every technician who works under the Mercer name is held to the Threshold Verified standard: background-checked, identity-verified, uniformed, and photo-badged. That’s not just a nice touch. It’s the foundation that makes the written guarantee worth the paper it’s printed on.
Why Austin Homeowners Need a Written Roofing Guarantee
Roofs in Austin take a beating. We get hail in the spring, brutal sun from June through September, and wind gusts that tear shingles loose in the middle of an otherwise calm afternoon. That weather means roof repairs are common, and it also means the difference between a good repair and a bad one might not show up for months. A loose shingle can hold until the next storm. A small flashing gap can leak slowly, staining your ceiling only after rain finds the path. That’s why a one-year, written workmanship guarantee matters. It’s not about trusting the crew. It’s about knowing that if the repair didn’t hold through the full cycle of Austin weather, the fix is on us, not you.
Real Talk From the Roof
We don’t expect you to take the guarantee on faith. Here’s what Grant Whitlock tells homeowners who ask about it: if one of our repairs fails within the year, we send someone out. The second visit is free, it’s already part of the deal, and we don’t make you call three times to get scheduled. He’d rather spend an afternoon re-sealing a flashing than lose a customer over a $200 repair. That’s the whole business model. Do it right the first time, fix it fast if it wasn’t right, and keep the homeowner’s number saved in our phone as a customer, not as a complaint.

AfterHow the Threshold Standard Protects You
Every Mercer Roofing Co Austin technician operates under the Threshold Group quality framework. That means the person who shows up at your door has already passed a background check and identity verification. They arrive in a clean, marked uniform with a photo ID badge they show at the door. Before they arrive, you’ll get their name and photo, so you know exactly who’s expected. It’s a small thing, but it changes the whole dynamic of a home service visit. You’re not opening your door to a stranger. You’re opening it to a verified professional whose name you already know. And if you’re one of the many Austin homeowners who’s paid a deposit to a “contractor” who never showed up for day two, the Threshold Standard is worth its weight in shingles.
What the Guarantee Does Not Cover
We’re straightforward about this because a guarantee that hides its limits isn’t a guarantee, it’s marketing. Our 365-day workmanship guarantee covers the quality of our installation and repair work. It does not cover damage from new storms, falling tree limbs, or foot traffic on the roof after we leave. It does not extend the manufacturer’s shingle warranty. What it does cover is the one thing we can control: whether the work we did holds up the way it should. If we made a mistake, we own it. If a storm wrecked a perfectly good repair, that’s a new job, and we’ll give you the same written pricing before we start.
Frequently Asked Questions
We guarantee our workmanship for 365 days from the date the job is completed. If the work fails within that year because of how we installed or repaired it, we return and fix it at no charge. The guarantee is written on every job, and a free second visit is included with every repair if it fails.
You call us at (361) 202-8874 and a live person answers. We schedule a technician to come back and inspect the repair. If it failed because of our workmanship, we fix it for free. No deductible, no “diagnostic fee,” no hoops. The free second visit is part of the deal from day one.
Our 365-day guarantee covers workmanship, not the manufacturer’s material warranty. That said, we install GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral shingles, all manufacturer-recognized brands with their own product warranties. We’ll explain what your specific shingle warranty covers when we quote the job.
Always. We provide a written price before any work starts, on every job, whether it’s a small roof repair or a full roof installation in Austin. The price on that written estimate is the price on your invoice. If something changes during the job, you hear about it before we spend a dollar, not after.
Every Mercer Roofing Co Austin technician is background-checked, identity-verified, and dispatched under the Threshold Verified standard. They arrive in clean, marked uniforms and show a photo ID badge at the door. Before they arrive, we send you the technician’s name and photo, so you know exactly who’s coming to your home.
Yes. A live person answers our phone 24/7. You will not get a voicemail box, an automated menu that loops for five minutes, or a call-back form. You’ll get a human being who can schedule your estimate or listen to your concern. Call (361) 202-8874 and you’ll hear a voice, not a recording.
The 365-day workmanship guarantee is tied to the original project and the homeowner who contracted the work. If you’re selling your home within the year after a Mercer job, call us and we’ll be happy to explain what the new owner can expect and provide documentation of the work performed.
