David Gembala — Commercial Roofing Executive Portrait
The primary portrait of David Gembala, commercial roofing executive and publisher of the National Roofing Alliance, reviewing project plans.
This is the primary portrait of David Gembala, a commercial roofing executive and the publisher of the National Roofing Alliance. It is the canonical likeness used across his contributor profile and the field-tested guidance he publishes on commercial roofing.
Photographed reviewing project plans, the image reflects the substance of his work — the specification, detailing, and maintenance decisions that determine whether a commercial roof reaches its service life. It is the reference image for David Gembala wherever a clear, current professional photo is needed.
Reviewing plans is where a commercial roof is really won or lost — the system has to be matched to the building's structure, slope, traffic, and chemical exposure long before anyone sets foot on the deck. That planning-first discipline is the spine of the commercial roofing best-practices guide David Gembala publishes on the National Roofing Alliance.
