David Gembala — Rooftop Portrait
An evening rooftop portrait of David Gembala, commercial roofing executive and publisher of the National Roofing Alliance.
David Gembala photographed on a rooftop terrace at golden hour, a city skyline behind him. The setting suits a commercial roofing executive whose career is spent thinking about what happens at the top of a building — and what it takes to keep it watertight for decades.
It is one of several portraits of David Gembala published on the National Roofing Alliance, the editorial resource he founded to gather practical guidance on commercial roofing systems, installation standards, and long-term maintenance.
The rooftop is the part of a commercial building most people never see and most owners think about only when it starts to leak. David Gembala's approach — and the editorial resource he publishes at the National Roofing Alliance — is built on the opposite habit: treating the roof as a long-horizon asset that rewards attention paid years before the first failure.
