What size are the skylights in this collection?

These are inside square skylights designed to fit standard square roof openings on most RVs and campers. Measure the inside dimensions of your existing skylight opening before ordering, and confirm the cutout size matches the replacement you are considering. If you also need related ventilation parts, see our Ventline Vent essential accessories.

Are these skylights compatible with my RV roof?

These square skylights are designed for standard RV and travel trailer roof openings. Check the listed cutout dimensions against your current opening, and verify your roof material (rubber, fiberglass, or aluminum) so you can pair the skylight with the correct sealant and butyl tape during install.

What if I need a premium replacement skylight option?

If you want a higher-grade replacement with thicker acrylic and improved UV resistance, browse our Icon Premium Skylights collection. These are a direct fit for many of the same openings covered here.

How do I install a replacement square skylight?

Remove the interior trim ring, then unscrew the existing skylight and break the old sealant bond. Clean the roof surface, apply fresh butyl tape under the new flange, set the skylight, fasten it down, and seal the screw heads and flange edge with a self-leveling lap sealant rated for your roof type. Always confirm your model number and cutout dimensions before ordering to make sure you get the correct fit.
