The Mercer Roofing Co Orlando Guarantee
When we say a roof is done right, we mean it stays right through Florida’s wet season, the dry-season heat that bakes shingles into brittleness, and the afternoon downpours that find every weak seam. Our 365-Day Done Right Promise is simple: if the work isn’t right within a year, Mercer makes it right. No fine print about which months count. No phone tree to argue with. Every repair leaves with a written guarantee, and if that repair fails, the second visit is free. In Orlando, where a small leak becomes a ceiling stain fast, that guarantee is the difference between a contractor who shows up once and a roofing company you’ll actually call again.
What’s Covered
- Workmanship on every repair and installation. If our crew’s work fails within 365 days, we return and fix it at no charge, full stop.
- Written guarantee included with every job. You’ll have the terms on paper before we pack up, not a verbal promise that evaporates.
- Free second visit if a repair fails. Same problem, same spot, within the guarantee period? We come back without sending an invoice.
- Written price before any work starts. You’ll see the full cost in writing before a single shingle is pulled, so there’s no surprise line item at the end.
- Clean, marked, badge-verified technicians. Whoever arrives at your door wears a clean uniform, carries photo ID, and was background-checked and identity-verified before dispatch.
- Manufacturer-recognized materials. We install and repair with shingle brands including GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so the materials stand behind the labor.

Our Satisfaction Promise
If something doesn’t look right, sit right, or hold right, you call the number on your paperwork and a live person answers. Not a voicemail box, not an automated callback queue. You explain the issue, we schedule the return visit, and the technician who shows up already knows what happened. We don’t make you re-litigate the original job. The 365-Day Done Right Promise isn’t a warranty you have to fight for; it’s a standing instruction our crews work under. If the repair doesn’t hold, the second visit is free. If the workmanship wasn’t what we promised, we make it right on our dime. Grant Whitlock owns this location, and he’s the one who authorized that promise, which means the person you can hold to it is someone whose name you actually know.
Licensed & Insured Backing
Anyone can print “quality” on a truck door. A license and insurance are the only guarantees that carry weight when something goes sideways. Mercer Roofing Co Orlando operates licensed and insured, which means the work is done under the standards Florida requires and the coverage protects your property while we’re on it. That matters in Orlando, where roofing crews are a constant presence and not all of them are legitimate. Our insurance protects you, our license keeps us accountable, and the Threshold Verified standard that every independently owned Mercer location operates under adds another layer: background-checked, identity-verified technicians on every visit. That’s the real backing behind the paperwork.
What the Guarantee Does Not Require
A guarantee only matters if claiming it is easy. Here’s what you won’t encounter with Mercer Roofing Co Orlando:
- No registration forms. You don’t fill out a warranty card or mail in proof of purchase. The written guarantee is handed to you at the end of the job.
- No “normal wear” exclusions on workmanship. If our installation fails because of how it was installed, that’s covered. We don’t hide behind vague carve-outs.
- No escalation maze. You call, a person answers, and the process starts. You won’t be transferred four times.
Threshold Standard: What It Means for Your Roof
Mercer Roofing Co Orlando is part of the Threshold Group family of home service companies, founded in 2000. Each location is independently owned and operated, but every one is contractually held to the Threshold Standard. For you, that translates to a technician who arrives in a clean, marked uniform, presents a photo ID badge at the door, and whose name and photo are sent to you before they arrive. That’s not a nicety. It’s a vetting framework that means the person on your property has been background-checked and identity-verified before they ever park in front of your house. In a city like Orlando, where roofing work happens on thousands of homes every year, knowing exactly who is walking up your driveway is the baseline of trust, not a bonus.

AfterHow the Free Second Visit Works
The guarantee is straightforward in practice. Say you had a repair done above your garage in College Park, and three months later a hard afternoon storm drives water back into the same seam. You call us, we send a technician to inspect it, and if it’s the same repair failing, the visit and the fix are free. No deductible, no trip charge, no “well, technically the warranty only covers the specific shingle, not the surrounding area” gamesmanship. Grant Whitlock put this guarantee in writing because he has seen too many Orlando homeowners pay twice for the same repair from roofers who won’t answer the phone the second time. We answer the phone.
Why a Written Guarantee Matters More Than a Warranty Brochure
Manufacturer warranties cover material defects, which is important but incomplete. They don’t cover whether the flashing was installed so it actually diverts water, or whether the decking was inspected before the new shingles went down, or whether the underlayment was laid correctly under the valley where two roof planes meet. That’s workmanship, and workmanship is on us. Our written guarantee covers what we did with our hands and our judgment. When paired with shingle brands like GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, you get two layers of protection: the manufacturer stands behind the product, and Mercer Roofing Co Orlando stands behind the installation. That combination is what “done right” actually means when the next Orlando thunderstorm rolls through.
What Happens When You Call About a Guarantee Issue
You dial (850) 757-3564. A live person answers, 24/7. You tell them the address and the issue. They pull up the job record, confirm the repair or installation date, and schedule the return visit. The technician who comes out already knows the history of the roof, which means they’re not starting from zero on your problem. If the failure is covered under the 365-Day Done Right Promise, the fix happens at no charge. If the issue is something new and unrelated, you’ll get a written price before any work starts, same as every other visit. Either way, you’ll know where you stand before anyone climbs a ladder.
