Flashing & Roof Integration
Water can enter where the skylight meets the roof if head, side, sill or surrounding flashing details no longer manage water correctly.
Residential Skylight Roofing
Skylight repair and installation in BC, starting with the source of the problem.
A leaking skylight does not automatically mean the skylight unit has failed. Water can enter around flashing and roof details, while interior condensation can create similar symptoms. The right repair starts by separating the skylight, surrounding roofing and indoor moisture conditions.

Leaking skylight?
Check the roof flashing, skylight unit and interior moisture pattern before
assuming the glass or frame must be replaced.
Similar symptoms can come from very different causes.
The skylight, roof flashing and interior light-well area should be considered together so the recommended work addresses the actual source.
02
Skylight Unit Condition
Age, frame condition, glazing seals and parts availability can affect whether the skylight should be repaired, retained or replaced.
03
Condensation & Interior Moisture
Moisture around the frame or light well can come from indoor humidity and insulation conditions rather than rain entering from outside.
Repair, Replace or Reflash?
Diagnose the roof-to-skylight connection before choosing the scope.

A skylight leak can be a roofing problem, a unit problem or condensation.
Replacing the skylight without addressing failed roof integration can leave the leak unresolved. Rebuilding flashing around a failed unit can create the opposite problem. The inspection should separate those conditions before work begins.
Review the leak pattern
Note whether moisture appears only during rain, during wind-driven rain or even in dry weather when interior humidity is high.
Check surrounding roofing and flashing
Review the roof details around the opening, including water-shedding paths, underlayment integration and visible flashing condition.
Evaluate the unit and interior conditions
Consider frame and glazing condition along with interior humidity, insulation and the light-well area before deciding on replacement.
Repair the detail, replace the unit or coordinate a new installation.
The correct scope depends on what has actually failed and how the skylight integrates with the existing or new roof.
Skylight Flashing Repair
When the unit remains serviceable, a localized problem may involve roof integration or flashing rather than the skylight itself.
Skylight Replacement
Replacement can be considered when the unit is no longer serviceable, seals or frame condition are problematic, or compatibility with new roofing is a concern.
New Skylight Installation
New openings should be coordinated with roof slope, framing, underlayment, flashing, drainage and the selected roofing system.
Wind-driven rain can expose weak skylight flashing details.
A skylight may appear dry during ordinary rain but leak when wind changes how water reaches the head, side or corner details. That pattern can provide useful diagnostic context before deciding whether the roof flashing or skylight unit needs attention.
From leak symptom to a defined skylight scope.
Keep diagnosis, roof integration and unit condition connected so the repair or installation addresses the actual cause.
Describe the Symptom
Share when moisture appears, recent weather conditions, the skylight age if known and any previous roof or skylight work.
Review Roof & Skylight Details
Check the accessible unit, flashing, surrounding roofing and interior conditions relevant to the reported problem.
Choose Repair or Replacement
Separate flashing repair, skylight replacement and condensation-related work instead of treating every leak as the same failure.
Complete the Roof Integration
Keep approved changes and completion details tied to the final skylight and roof scope.
Follow the problem to the page that owns the next decision.
Skylight work often overlaps with leak diagnosis, localized roof repair or a larger roof replacement project.
Roof Leak Detection
Use leak detection when the moisture source remains unclear after considering the skylight and surrounding roofing.
Roof Leak Detection
Roof Repair
Move to the repair page when the skylight concern is part of a broader localized roofing or flashing defect.
Roof Repair
Roof Replacement
Coordinate skylight decisions with roof replacement when the surrounding roof is already being renewed.
Roof ReplacementCommon questions about leaking and aging skylights.
The main goal is to distinguish roof integration, unit condition and condensation before choosing repair or replacement.
How do I know whether a skylight leak is from the roof or the skylight itself?
The source can involve roof flashing, curb details, glazing seals or interior condensation. The inspection should compare the leak pattern, surrounding roofing, skylight frame and interior conditions before deciding what needs repair.
Can skylight flashing be repaired without replacing the skylight?
Sometimes. If the skylight unit remains serviceable and the problem is limited to surrounding roof or flashing details, repair may be possible. The condition and compatibility of the existing unit should be reviewed first.
Should an older skylight be replaced during a roof replacement?
It can be worth evaluating the skylight's age, seal condition, parts availability and compatibility before the surrounding roof is renewed. Replacing the unit later can require disturbing newer roofing.
Can condensation around a skylight look like a roof leak?
Yes. Interior humidity, insulation and cold surfaces around the skylight or light well can create moisture that resembles exterior leakage. Weather patterns and interior conditions can help separate condensation from rain entry.
