Skylight repair and installation
A skylight leak may come from glazing seals, flashing, an improperly built curb, condensation or roofing higher on the slope. Our team assesses the roof, explains the practical options and prepares a scope that fits the building, access and timing.
Replacement often makes sense when the unit is old, glazing seals have failed or the roof is being replaced and the skylight is near the end of its service life. The written scope should connect that decision to the roof's observed condition.
What a proper assessment looks for
The visible symptom is only the starting point. Materials above, below and beside the affected area need to be reviewed so the estimate reflects the actual water path and the condition of the substrate. The field review also checks head, side and sill flashing arrangement.
- Head, side and sill flashing arrangement.
- Curb height, condition and membrane tie-in.
- Glazing, seals and weep paths.
- Water marks that suggest condensation rather than rain entry.

How the work moves from concern to closeout
Identify the moisture source
Compare interior staining with exterior details and weather conditions before removing components. Before approval, confirm how the contractor will assess glazing, seals and weep paths.
Repair or replace the right layer
Correct flashing and roofing, rebuild the curb or replace the skylight unit according to the actual failure. The first work stage is to identify the moisture source, followed by documentation of the observed condition.
Integrate surrounding materials
Restore underlayment and roof covering so water sheds around the opening without relying on exposed caulking. The estimate should connect each line item to an observed condition or stated project requirement.

What should be clear before approval
A complete scope identifies the work area, preparation, materials, flashing treatment, cleanup and any exclusions. It should also explain how concealed damage will be documented and priced if it becomes visible after removal. The field review also checks head, side and sill flashing arrangement.
Property protection and communication belong in the plan as well. Ask where materials will be staged, how landscaping or tenant areas will be protected and who will provide progress updates. The estimate should connect each line item to an observed condition or stated project requirement.
Why the surrounding roof matters
Replacement often makes sense when the unit is old, glazing seals have failed or the roof is being replaced and the skylight is near the end of its service life. The field review also checks head, side and sill flashing arrangement.
The inspection should also account for access, weather exposure, existing warranties and any related gutter, ventilation or wall details. That broader view prevents a narrow fix from moving water to the next weak point. The recommendation should stay centred on treating the skylight, curb and surrounding roof as one detail.

Questions customers ask
How is the scope for skylight repair and installation determined?
A skylight leak may come from glazing seals, flashing, an improperly built curb, condensation or roofing higher on the slope. The field review checks head, side and sill flashing arrangement, curb height, condition and membrane tie-in and glazing, seals and weep paths. For skylight repair and installation, each line item should connect to head, side and sill flashing arrangement.
When is a different or larger roofing scope more practical?
Replacement often makes sense when the unit is old, glazing seals have failed or the roof is being replaced and the skylight is near the end of its service life. The recommendation should compare expected service life, repeat-failure risk and the cost of each option. For skylight repair and installation, each line item should connect to head, side and sill flashing arrangement.
What should be shared before the inspection?
Provide the property address, roof type if known, where the problem appears, when it started and any safe photos. Mention access restrictions, active interior water and deadlines that affect scheduling. Also note any symptom or access issue related to glazing, seals and weep paths.
