Replacement Skylights

Our Solution – Skylight Retrofit

replacementWindy City Skylights can retrofit an existing fixed skylight.

A skylight retrofit installation includes:

  • Replacing the existing skylight with a new Velux low-E glass skylight
  • Replacing the flashing, skylight curb (frame) when necessary, and surrounding roof material

A skylight retrofit is applicable for acrylic, polycarbonate, and glass skylights that are leaking.

As an option, Windy City Skylights can do unforeseen work adjacent to the skylight, roof sheathing repair or replacement, attic space repair including  skylight shaft or ceiling repair, new trim work, or painting.

We offer an exclusive 15 year guarantee on the labor component of a Velux replacement installation, significantly more than most other installation companies.

Skylight Repair


  • A repair is done to extend the longevity of a Velux skylight. Repairs are generally categorized as simple part replacements or minor adjustments.
  • For repairs of non-Velux skylights, we offer the Retrofit option outlined above or the Replacement option on the Skylight Replacement page.
  • All repairs are dependent upon the availability of parts from Velux.
