Our Guarantee & Warranty - Mercer Roofing Co San Antonio

The Mercer Roofing Co San Antonio Guarantee

We don’t hand you a verbal promise and hope for the best. Mercer Roofing Co San Antonio puts every guarantee in writing before the first shingle comes off the truck. The 365-Day Done Right Promise means exactly what it says: if the work is not right within a year, we make it right. No fine print, no prorated nonsense, no arguing about whose fault it was. If we roofed it and it failed because of our workmanship, we’re back on that San Antonio roof fixing it at our cost. That’s the deal, written down, every single time.

What’s Covered

Here’s what you get in writing when you hire us for roof repair, roof installation, or any roofing work in San Antonio:

• Written guarantee on every repair, included with every job. If the repair fails, a second visit is free. Not discounted, not “we’ll take a look when we’re in the area.” Free, scheduled, and handled like a new job.
• A written price before any work starts, always included, never conditional. You’ll see the full scope and the full price in writing before you approve anything. No surprises on the invoice, no change orders that show up after the fact.
• The 365-Day Done Right Promise on workmanship. From the day we finish until day 365, if our work isn’t holding up the way it should, we come back and make it right. That’s a full year of accountability.
• Manufacturer-recognized shingle brands. We install and repair using GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. These aren’t off-brand materials; they’re the shingle lines manufacturers train installers on and stand behind with their own material warranties.
• Background-checked, photo-badged technicians on every visit. Every Mercer Roofing Co San Antonio technician is background-checked, identity-verified, and arrives in a clean, marked uniform with a photo ID badge. You’ll know who’s showing up before they ring the bell, because their name and photo are sent to you ahead of time.
• Cleanup on every job. Nails, shingle scraps, old flashing, torn-off underlayment, all of it gets hauled off and the ground gets swept. We don’t leave your yard looking like a storm hit it, because that’s part of the job, not an upsell.

Our Satisfaction Promise

Here’s how the make-it-right process actually works, because we believe you deserve to know the mechanics, not just the slogan. You call us at (254) 276-4369. A live person answers, day or night, not a voicemail or a callback form. You tell us what’s wrong. We schedule a visit. A background-checked, photo-badged technician shows up, looks at the issue, and tells you straight what happened and what we’ll do to fix it. If the work falls under our 365-Day Done Right Promise or the written repair guarantee, the fix happens at no cost to you. If you’re unhappy with an installation or a repair for any reason within that year, call us and we’ll make it right. That’s the entire promise, stated plainly: we do the job right, and if we don’t, we fix it. No escalation games, no “that’s not covered” runaround. You call, we show up, we make it right.

Licensed & Insured Backing

A guarantee is only as strong as the company behind it, and behind Mercer Roofing Co San Antonio is a licensed and insured operation. What that means for you is real protection, not a piece of paper. If something goes wrong on the job, insurance is there to cover it. If a question ever comes up about the work, you’re dealing with a licensed contractor, not a guy with a ladder and a pickup truck who disappears when the rain comes. Grant Whitlock, Owner, built Mercer Roofing Co San Antonio on the principle that the paperwork matters as much as the shingles, because the paperwork is what protects you when the shingles fail.

What About Manufacturer Warranties?

Here’s the part most roofing companies blur. There are two different layers of protection on any roof, and they cover different things. The manufacturer warranty covers the shingles themselves, the material. If a GAF or CertainTeed shingle has a manufacturing defect, the manufacturer’s warranty kicks in. But the manufacturer does not warranty the installation. That’s the second layer, and it’s on us. Our workmanship guarantee covers the installation and repair work we do, the part the manufacturer has nothing to do with. So when a San Antonio homeowner asks us who covers what, we give them both answers, clearly. The shingle brand covers the shingle. Mercer Roofing Co San Antonio covers the work. Both matter, and you should know which one you’re leaning on before you ever file a claim.

How the 365-Day Promise Works in the Real World

Roof problems in San Antonio don’t always show up on day one. A loose flashing detail can hold through the dry spring and leak during the first heavy Hill Country thunderstorm in May. A shingle that wasn’t seated quite right can hang on until a big wind event catches it and peels it back. That’s exactly why our promise runs a full 365 days, not 30, not 90. We want you to live through a full Texas weather cycle with your new roof or repair before the guarantee clock runs out. Hail season, summer heat, fall winds, winter rain, the whole year. If something we did fails during that span, we come back and fix it. Grant Whitlock and the whole Mercer Roofing Co San Antonio team stand behind that, not because we’re optimistic about the weather, but because we’re confident in the work.

Why We Put It in Writing

Verbal promises are worth what they’re printed on: nothing. Every guarantee from Mercer Roofing Co San Antonio, from the written repair guarantee to the 365-Day Done Right Promise, comes in writing, on paper, before any work starts. You don’t ask for it. It’s included, always, no conditions. That’s the way we’ve done it since the company was founded in 2000 as part of the Threshold Group family of home-service companies. The Threshold Standard, which every independently owned and operated Mercer location is held to contractually, requires background-checked, identity-verified, badge-wearing technicians on every visit. We meet that standard on every job, every time, no exceptions. So the written guarantee isn’t a marketing line; it’s the natural extension of how the whole company runs.

Questions San Antonio Homeowners Ask About Our Guarantee

Does the guarantee cost extra?

No. The written repair guarantee is included with every repair job at no additional cost. The 365-Day Done Right Promise is included with every installation and repair. You never pay extra for the promise, and you never have to opt in. It’s part of the job, just like the written price we provide before any work starts.

What if a repair fails six months later?

You call us at (254) 276-4369, a live person answers, and we schedule a free second visit. The repair guarantee is written and included with every job, so if the fix doesn’t hold, the return trip and the re-repair don’t cost you anything.

Will the price change once work starts?

No. We give you a written price before any work starts, every time, and that’s the price you pay. If the scope changes for any reason, we talk to you about it first and put any changes in writing before we proceed. The invoice matches the agreement, and the agreement is always in writing.

Who actually does the work on my roof?

Mercer Roofing Co San Antonio technicians, not subcontractors you’ve never heard of. Every technician is background-checked, identity-verified, uniformed, and photo-badged under the Threshold Verified standard. Before the visit, you get the name and photo of the technician coming to your door. When they arrive, they badge in, so you know exactly who’s on your property.

What if I notice a problem after the 365-day window?

Call us anyway. The 365-Day Done Right Promise covers workmanship for a full year, but we don’t stop caring about our work on day 366. Every situation is different, and we’ll talk to you honestly about what’s covered, what’s not, and what your options are. The phone number is (254) 276-4369, and a live person answers 24/7.
