Agree on the location
Consider the room below and the framing, wiring, ducts and roof shape above it.
Water near a skylight can come through the glazing or frame, the flashing around it, or another nearby roof detail. Condensation can also leave moisture inside. Replacing the glass will not correct a flashing defect, and another bead of sealant will not fix every failing unit.
Our roofers can investigate the source and explain the repair or replacement options. If water is entering now, describe it when requesting leak repair.

Start with what the room needs, then check the roof and the space above the ceiling. Location, structure, slope and the product’s requirements shape the installation.
A fixed unit brings in daylight without opening. Consider the view, glare and heat-control options as well as size.
An opening unit can provide ventilation where its location and controls are practical. It doesn’t replace required kitchen or bathroom exhaust.
A reflective tube can bring light into a smaller or interior space. The route still needs to fit around framing and other obstructions.
Compare the actual glazing, shading, controls and product ratings. A hail rating does not make a skylight immune to damage.
Consider the room below and the framing, wiring, ducts and roof shape above it.
Deck-mounted and curb-mounted products have different installation details. Any structural alteration needs an appropriate plan.
Use the product’s specified components and details for the roof covering and slope.
Clarify responsibility for the shaft, insulation, drywall, trim, paint and any electrical connection before work begins.
Understand the controls, care and the product and installation coverage offered.
VELUX provides separate installation instructions for different mounting and product types. A raised curb is not a requirement for every skylight.
The condition of the unit and the surrounding roof matters more than a fixed birthday. Sound flashing with a limited sealant defect is a different case from split metal, damaged glazing or a distorted frame. Repeated resealing deserves another diagnosis.
An insulated glazing seal may have failed. An exterior roof patch can’t restore that sealed space.
Have the unit assessed for a suitable replacement or manufacturer-supported repair.
The detail may need rebuilding instead of another surface treatment.
Consider the skylight and its flashing in the same proposal so the work fits together.
Replacing a unit in a suitable existing opening is different from cutting a new opening and building a finished shaft. Roof height and slope, framing changes, flashing and electrical controls can all affect the cost.
Ask which indoor and outdoor work is included. A skylight price that leaves out the shaft and interior finish can be difficult to compare with a complete installation. If you’re also replacing the roof, identify the skylight work separately within that scope.
No. The leak may come from a repairable connection around a sound unit. The inspection needs to distinguish the flashing, the unit and other possible moisture sources.
Read the actual product and installation warranty. Some systems include specified installation coverage, while others have different limits or eligibility requirements. The location of the leak alone does not settle responsibility.
It is useful to assess both together. The unit’s condition, compatibility with new flashing and the cost of returning later all matter. A sound, suitable unit may be retained.
It may fit between existing members, but the roof-to-ceiling route must be checked. Do not assume a particular room has an unobstructed path.

Describe the room, whether an opening already exists and any leak or damage. Our roofers can help you understand the work involved.
