David Gembala
Decades of operating history in commercial roof systems — and a working conviction that most roof failures are decision failures. David Gembala speaks and writes on how better decisions get made.
Three arguments, made from experience
Pick the system for the building
Commercial roof assemblies should be matched to structure, slope, traffic, and exposure — not to habit or bid-day price. Most premature failures are written into the spec.
Maintenance is the cheap part
The economics of commercial roofing favor the owner who walks the roof. Inspection and small repairs are rounding errors next to early replacement.
Safety is a leadership output
Roofing is among the most hazardous trades. Crews take fall protection as seriously as the people running the company demonstrably do.
