Commercial skylights can leak at glazing seals, frames, curbs, fasteners and adjacent roof flashings. Condensation should also be distinguished from roof water entry.

Representative rooftop detail, not a photograph of a specific completed repair.
For commercial owners and property managers, roof leaks can affect insulation, interior finishes, equipment and normal operations. Water can migrate before showing indoors, so a visual stain does not always identify the actual entry point.
Potential warning signs
Drips below daylighting units, fogging, cracked glazing seals or wet curb interiors. These observations help communicate the issue but do not confirm the source without inspection.
Distinguish condensation from rainwater intrusion and review glazing, curb flashing, frame joints and drainage.
Visible water-entry symptoms and previous repair areas
Adjacent flashings, seams and roof transitions
Possible damp insulation or deterioration beneath the roof surface
Material compatibility, access and building operations
Possible repair approaches
Repairs may involve glazing seals, frame components or roof-to-curb waterproofing.
Important consideration: A skylight problem is not always a roof-membrane defect and may require glazing expertise.
Commercial repair planning
Any repair should address the actual water-entry path, not simply conceal an interior stain. The selected professional should evaluate surrounding materials, roof access, existing warranties and any work that may affect occupied spaces.
