From Legacy to Lift-Off: How HMAC Roofing Builds Trust—and Where It Meets Offsite

Melinda Hegarty of HMAC x Audree Grubesic of Offsite Dirt Network

Family businesses are built on more than a logo—they’re built on people, promises, and a track record that survives storms. In this Offsite Construction Series episode, Audrey sits down with Melinda Hegarty of HMAC Roofing to unpack a 40-year story that started with her father, Hugh McDonald, and grew into a multi-division roofing operation serving Florida’s West and East coasts.

What stands out first is HMAC’s warranty mindset: “We always go look.” Whether it’s a suspected defect or a mystery leak, the team shows up, diagnoses, and makes it right—no finger-pointing, no runaround. That service DNA started in Melinda’s first role handling service and warranty calls, where she learned exactly what can go wrong on a roof—and how to prevent it.

Today, HMAC spans custom homes, production homes, townhomes, and re-roofing operations, supported by an in-house sheet-metal shop and a door & trim business. The footprint is big—Tampa Bay/Pinellas across to Daytona, down to Port St. Lucie, and throughout Orlando—but the model stays tight: roofers are employees, not subs, which means HMAC can deploy crews quickly and keep quality consistent.

As a woman leading in construction, Melinda brings a consumer-centric lens to communication and problem solving—translating technical issues into practical solutions homeowners understand. It’s also why she’s a natural fit for the offsite world: consistent quality, phone calls answered (6:30 a.m.–5 p.m. on weekdays), trained teams, and the capacity to integrate roofing as a plug-in trade wherever manufacturers need it—whether modules ship with roofing complete or require onsite finish.

Where does HMAC meet industrialized construction? With skilled labor, predictable scheduling, and a “do the right thing” culture that factories and GCs can rely on. If offsite is about repeatability and speed without sacrificing durability, HMAC’s legacy approach—show up, fix it, and stand behind it—fits right in.
