Service for Columbus commercial properties
Most commercial skylight leaks in Columbus are not skylight failures — they are flashing failures at the curb-to-roof interface. Before replacing the unit, let us determine whether the problem is the skylight or the roof around it.
Commercial skylights are among the most leak-prone points on a Columbus commercial roof — but not always for the reason building owners assume. A waterfall at the ceiling below the skylight is often attributed to a cracked dome or failed glazing seal. In our experience across Columbus office buildings, retail centers, and institutional buildings, the majority of commercial skylight leaks originate at the flashing interface between the skylight curb and the roof membrane, not at the glazing unit itself.

Service decisions are tied to leak history, roof age, membrane condition, drainage, tenant sensitivity, access, and the capital plan behind the property.
The next step is a repair scope, replacement budget, coating review, maintenance schedule, bid package, moisture survey, or immediate leak response plan.
Questions
A leak that produces water at the immediate perimeter of the skylight — at the curb corners or along the curb edge — is typically a flashing failure. A leak that produces water dripping from the center of the skylight opening or from the glazing unit itself is typically a glazing unit failure. The two can coexist. We use a flood test to confirm source location before recommending a repair scope.
Yes — in most cases, yes. If the skylight curb and unit are structurally sound and the leak is at the flashing interface, re-flashing is the correct repair. Unit replacement is only warranted when the skylight itself has failed — cracked dome, failed insulated glass, structural curb damage. Recommending unit replacement for a flashing failure is an upsell that solves the wrong problem.
Curb re-flashing cost depends on curb perimeter length, membrane type, and accessibility. A standard single curb skylight on a single-story Columbus commercial building is a half-day repair. Multi-curb assemblies or skylights in restricted access locations take longer. Contact us at 614-877-6720 for a site-specific assessment.
