Review existing skylights when planning a roof replacement. Their condition, mounting method and flashing requirements affect how they should be integrated with the new roof. Coordinating the work can avoid disturbing new roofing later, but the decision should be based on the actual skylights and a clear proposal—not a blanket promise of savings.

Why discuss skylights before the reroof starts?

A skylight creates a junction in the roof that needs compatible weatherproofing. When surrounding roofing is removed, the installation plan should address the skylight, its flashing and the adjacent materials together. Leaving those decisions until tear-off can create uncertainty about cost and scope.

VELUX recommends reviewing replacement during reroofing. Its replacement installation guidance also highlights measurements and roof-pitch requirements. Those are manufacturer-specific instructions, not a claim that Hawk Eye is a VELUX-certified installer or that one product suits every roof.

What should be assessed on an existing skylight?

  • The product model and installation date, if known.
  • The condition of the frame, glazing and visible seals.
  • Staining or leakage around the opening.
  • The mounting arrangement, roof material and slope.
  • The flashing system and requirements for its replacement or reuse.

Condensation, glass-seal issues and leakage at the roof junction are different concerns. Describe what you see and when it happens rather than assuming every stain means the entire unit has failed. Ask about skylight work alongside the roofing assessment.

What belongs in the replacement proposal?

Identify which units will be kept or replaced, the proposed models, compatible flashing, underlayment integration and any work to the opening or interior finish. Ask what is excluded and how concealed damage would be handled.

Review the actual product and workmanship warranty documents. Coverage depends on the product and installation terms; replacing roof and skylight together does not automatically create a combined warranty. Any approval, glazing or performance requirement needs to be checked for the specific project.

Can this be considered without replacing the whole roof?

Yes—the first conversation can be about the skylight alone. A concern at one opening does not establish that the whole roof needs replacement. Compare the condition of the skylight and surrounding roof before choosing between focused work and a broader roof replacement.
