Meet the Miami Team Behind Mercer Roofing Co Miami
If you live in Miami, you already know the drill. Intense sun, hurricane season, and afternoon thunderstorms that show up out of nowhere. The crew at Mercer Roofing Co Miami works in that weather year-round, and they’ve learned to read it the way a fisherman reads the tide. What unites them is simple: they badge in at the door, put the written price in your hand before anything starts, and do the job once. That’s the whole philosophy. No mystery, no pressure, no surprises on the invoice.
Styles & brands we work with






Our People
Luis R. – Lead Technician
Luis has been on Miami roofs since he first started carrying shingle bundles up a ladder. He’s the guy who walks your roof first, takes the photos, and tells you straight what needs replacing and what can wait. He’s GAF and CertainTeed certified, which matters when you want the manufacturer’s material warranty to actually stick. Off the clock, Luis rebuilds small engines in his garage in Westchester. If he quotes you a repair, he’s already worked out three ways to do it before he climbs down.
Dana M. – Senior Installer
Dana leads the install crew on full roof replacements across Miami, from Kendall to Coconut Grove. She’s our Owens Corning and Atlas specialist and has installed every major shingle brand Mercer works with. Dana is particular about flashing and decking. She’s the first to notice when old plywood under the shingles has gotten soft from years of humidity and salt air, and she’ll show you exactly what she found before a single new sheet goes down. She grew up in Hialeah and knows the local building code like it’s a second language. Her installs pass inspection on the first visit more often than not.
Carmen T. – Service Coordinator
Carmen is the voice on the phone when you call Mercer Roofing Co Miami. She doesn’t route you to a call center. She works from the Miami office and knows which tech is in your neighborhood on any given day. Carmen schedules the estimate, makes sure the written price gets to you before work starts, and confirms the technician’s name and photo are sent to you ahead of the visit. She’s been coordinating roofing jobs in Dade County for over a decade. If there’s a permit question or a HOA form, she’s the one who chases it down so you don’t have to.
Andre W. – Apprentice
Andre is the newest member of the Miami crew, learning the trade under Luis and Dana. He handles material staging, cleanup, and tool support on every job, but he also spends time on the roof observing flashing repairs and underlayment work. Andre is background-checked, identity-verified, and wears the same Threshold Verified photo badge as every other technician on the truck. He’s originally from Little Havana and wants to earn his own manufacturer certifications within the next two years. When you see a second person on the roof handing up bundles and holding the ladder, that’s usually Andre.
One Standard, Every Job
Every person listed above follows the same playbook on every visit to a Miami home. They arrive in a clean, marked uniform with a photo ID badge at the door. You get their name and photo before they ever turn the corner onto your street. The price is written down before any work starts. If a repair doesn’t hold, a second visit is free, and that’s in writing too. Grant Whitlock, Owner, keeps the Miami location to this standard because it’s what he’d want for his own roof. Mercer Roofing Co is part of the Threshold Group family, founded in 2000, and each location is independently owned and operated. But the Threshold Verified standard is a contract, not a suggestion. Background-checked, photo-badged, uniformed, and held to a 365-Day Done Right Promise. That’s who shows up in Miami.
