The Mercer Roofing Co Miami Guarantee

We put it in writing before we put a single nail in your roof. That’s the core of how Mercer Roofing Co Miami has operated since 2000, and it hasn’t changed. Every repair we make in Miami comes with a written guarantee, and that guarantee says something specific: if our repair fails within 365 days, we come back and fix it at no charge. No phone tag, no fine print, no argument about whose fault it was. That’s the 365-Day Done Right Promise, and it’s been the backbone of our work since Grant Whitlock started this company. You get a written price before any work starts, a written guarantee when the work is done, and a live person on the phone if anything goes wrong in between.

Call (850) 753-2996

What’s Covered

  • Workmanship for 365 days. If a repair we made fails within a year because of how it was installed, we return and make it right at no cost to you.
  • Written price before any work starts. You’ll see the full cost in writing up front. No verbal estimates that drift, no surprise line items at the end.
  • Written guarantee on every repair. It’s not a handshake. Every repair gets a written guarantee included with the job, every time.
  • Parts and materials handled correctly. We work with manufacturer-recognized shingle brands like GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, and we follow their installation specs so your material warranties stay valid.
  • Cleanup when we leave. Roofing creates debris. We don’t leave nails in your driveway or shingle scraps in your flower beds. The site is clean when we badge out.
  • On-time arrival with identification. Every technician shows up in a clean, marked uniform and presents a photo ID badge at the door. You’ll know our name before we ring the bell.
  • Honest pricing. The written price you approve is the price you pay. No change orders invented after the fact, no “we found more damage” phone calls that double the bill.

Our Satisfaction Promise

Here’s exactly what happens if something isn’t right. Call us. A live person answers the phone 24/7, not a voicemail, not a call-back form. You’ll describe the problem. We’ll schedule a return visit. If the issue falls within the 365-day guarantee period and relates to the work we performed, the second visit is free. That’s not a courtesy we extend when we feel like it; it’s written into every repair guarantee we issue in Miami. If the problem isn’t covered by the guarantee, we’ll still show up, look at the roof, and give you a written price for the fix before any work begins. You always know what you’re approving. That’s the whole point of the system: no ambiguity on day one, no ambiguity on day 300. Grant Whitlock built Mercer Roofing Co Miami on a simple idea. Roofs done once and done right, by a crew that badges in at the door. If that didn’t happen, we make it right.

Licensed & Insured Backing

A guarantee is only worth the paper it’s written on if the company behind it can actually follow through. Mercer Roofing Co Miami is a licensed and insured roofing contractor serving Miami and the surrounding areas. What that means for you is simple: the work is performed legally, inspected properly, and backed by coverage if something goes wrong on your property. We carry insurance because roofing is physical work done at height, and Miami’s storms don’t make it any easier. Licensing means we’re accountable to the state’s standards for roofing contractors. Insurance means you’re protected while the work happens. Together, they’re the real backing behind the written guarantee. If you want to see our credentials before you book, ask. We’ll show you. Call (850) 753-2996 to talk details or schedule a free estimate.

Why the Badge Matters in Miami

You’re going to let someone climb onto the roof of the home where you sleep. In South Florida, roof work isn’t optional maintenance; it’s the barrier between your family and hurricane season. You should know exactly who that person is before they set foot on your property. That’s the Threshold Standard, and it’s not a slogan. Every Mercer Roofing Co Miami technician is background-checked, identity-verified, and dispatched under the Threshold Group quality framework. Before your appointment, we send you the technician’s name and photo. When they arrive, they’re in a clean, marked uniform with a photo ID badge they present at the door. If the person at your door doesn’t match the badge, don’t let them in, and call us immediately. That system exists because Miami homeowners have every right to be cautious. You shouldn’t have to choose between a qualified roofer and a stranger on your property. You get both: verified training and verified identity, every visit, every time.

How the Guarantee Works with Manufacturer Warranties

There are two layers of protection on most roofing work, and they’re not the same thing. Our guarantee covers workmanship: how the repair or installation was performed. Manufacturer warranties cover materials: how the shingle itself performs over time. We install shingles from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, and we follow each manufacturer’s installation requirements so the material warranty remains valid. If a shingle fails because of a manufacturing defect, the manufacturer’s warranty may apply. If the roof leaks because of how it was installed, our 365-day guarantee applies. We’ll explain which layer applies to your situation when we assess the problem, in plain English, before you spend a dollar.

Questions Miami Homeowners Ask About the Guarantee

What exactly does the 365-Day Done Right Promise cover?

It covers workmanship on repairs we perform. If the repair fails within 365 days because of how it was installed, we return and fix it at no charge. Material defects are handled separately under the shingle manufacturer’s warranty. Call (850) 753-2996 and we’ll explain what applies to your specific roof.

Is the repair guarantee really included with every job?

Yes. Every repair includes a written guarantee, every time. It’s not an add-on, it’s not conditional, and it doesn’t cost extra. The guarantee is written, not verbal, so you have a document to reference if something goes wrong. That’s the standard Mercer Roofing Co Miami has operated under since 2000.

Will the price change once work starts?

No. You approve a written price before any work begins. That’s the price you pay. If we discover something unexpected during the job, we stop, explain what we found, and get your approval on any additional work before proceeding. You’re never surprised by an invoice. Call (850) 753-2996 for a free estimate and you’ll see exactly how the written price works.

What if the roof leaks again after a repair?

Call us. A live person answers 24/7. We’ll schedule a return visit. If the leak is related to work we performed within the 365-day guarantee period, the second visit is free. If it’s a new issue, we’ll give you a written price before touching anything. Either way, you’ll know exactly where you stand.

Do you pull permits when they’re required?

When roofing work in Miami requires a permit, we handle that process for you. Permits protect you by ensuring the work is inspected and approved by the city. We never cut corners on legal requirements, because a roof that isn’t permitted can become a liability when you sell your home. Ask about permits during your estimate and we’ll tell you exactly what your project needs.

Ready to Talk About Your Roof?

The guarantee starts with a conversation. Call (850) 753-2996 and a live person answers, day or night. We’ll send a background-checked, photo-badged technician to assess your roof and give you a written price before any work starts. If you don’t like the price, you walk away with a free assessment and a clearer picture of your roof’s condition. If you do move forward, you get the 365-Day Done Right Promise in writing. That’s how Mercer Roofing Co Miami has done it since 2000, and how we’ll do it on your home.
