For a commercial property, a roof problem is never just a roof problem. It’s interrupted operations, damaged inventory, and tenants asking questions. The good news for Palm Beach County business owners is that most commercial roof issues are far more repairable than the first contractor through the door will tell you — and a repair-first approach usually protects both the building and the budget.
At Mike McGilvary Roofing, we’ve worked commercial and industrial roofs across Palm Beach County since 1974. Here’s how we think about commercial roof repair, and what to look for before you approve a five- or six-figure replacement you may not need.
The commercial roof problems we see most in South Florida
Flat and low-slope commercial roofs take a specific kind of beating here: standing water after heavy rain, relentless UV that degrades membranes and sealants, thermal cycling that works seams loose, and wind-driven rain that finds every lifted edge. The most common calls we get are:
- Membrane leaks and seam failures — where two sheets of a flat-roof membrane meet, or where the membrane meets a wall, curb, or drain.
- Failed flashing and penetrations — around HVAC units, vents, skylights, and pipe boots, which are the first places a commercial roof tends to leak.
- Ponding water — low spots that hold water long after a storm, accelerating membrane breakdown.
- Storm and wind damage — lifted or punctured membrane, displaced flashing, and clogged or damaged drainage after a major weather event.
Repair first — replace only when the system has truly failed
The single most expensive mistake a commercial property owner can make is replacing a roof that needed a repair. A localized leak, a failed seam, or storm damage on an otherwise sound roof is a repair — not a reason to tear off the whole system. We inspect first, document what’s actually failing with photographs and attic or interior moisture findings, and tell you honestly where the roof stands.
A full commercial or industrial roof replacement is the right call only when the membrane has reached the end of its service life across the roof, the deck is compromised, or repeated failures show the system as a whole is done. When that’s the case, we’ll show you exactly why — and when it isn’t, we’ll fix what’s broken and leave the rest alone.
Minimizing downtime is part of the job
Commercial repair is as much about logistics as roofing. We schedule around your operating hours where we can, stage materials to keep walkways and loading areas clear, and prioritize getting the building watertight fast when a leak is active. When a roof emergency can’t wait, our 24/7 emergency roof repair team can tarp and stabilize the same day to stop interior damage while a permanent repair is planned.
Documentation that protects you
Every commercial inspection comes with a documented condition report. That record matters for budgeting, for insurance, and for the warranty conversation — and if your roof’s age is being questioned at renewal, a documented assessment of its real condition is far stronger than a number on a permit. (For more on that, see our guide to Florida’s Roof Age Law.)
