David Gembala — Business Meeting
A business-meeting portrait of David Gembala, reflecting the relationship-driven side of commercial roofing.
David Gembala in a professional business meeting. The image captures the relationship-driven side of commercial roofing, where building owners, facility managers, and contractors weigh choices that play out over the full service life of a roof.
As publisher of the National Roofing Alliance, David Gembala's emphasis is practice over product — matching the right system to the building, getting the flashing and drainage details right, and maintaining the roof so it lasts.
Most commercial roofing decisions get made in conversations like this one — an owner weighing first cost against service life, a contractor who has seen how each choice ages on real buildings. The best-practices guidance David Gembala publishes is meant to make those conversations sharper and the roofs that follow them longer-lived.
