A Windsor Skylight Leaks in Wind-Driven Rain: What Should Be Checked?
Separate the skylight unit, flashing and surrounding roof when investigating moisture around a Windsor skylight.
Read the guideWater around a skylight can come from the unit, its flashing, or the surrounding roof. Mario Contreras Roofing provides skylight repair assessments in Santa Rosa and Sonoma County to help identify which part of that connection needs attention.

Tell us whether moisture appears on the glass, at the frame, or on the ceiling around the opening. Note whether it occurs during rain or at other times. Condensation and exterior water entry are different problems, and a stain alone does not establish the repair.
If the skylight's brand or model is visible from inside, keep that information available. Unit type, roof slope, and the surrounding roofing affect the appropriate flashing and repair approach. Do not climb onto the roof to look for a product label.
A serviceable skylight may need work at the flashing or surrounding roof rather than a new unit. An older or damaged unit may make replacement more practical. Ask which parts of the assembly are included and whether interior finish work is part of the scope.
If a roof replacement is also being considered, discuss the skylight at the estimate stage. Coordinating the work can avoid reopening newly installed roofing later. The final recommendation should follow the condition of the existing unit and roof.
No. The flashing, frame, surrounding roof, and interior condensation can each be involved. Describe where and when you see moisture so the assessment can narrow down the source.
