What size square skylight do I need for my RV?

Measure the existing roof opening from inside edge to inside edge before ordering. Common RV square skylight sizes are 14" x 14" and 22" x 22" rough openings, with the dome itself running slightly larger to cover the flange. Confirm the inside opening, the outside dome dimension, and the rise (dome height) so the replacement matches both your roof cutout and any interior trim ring you plan to reuse.

Are these skylights compatible with Icon and other OEM units?

Yes. Many square skylights in this collection are direct replacements for common OEM domes used by Icon, Specialty Recreation, and similar manufacturers. If you want a like-for-like swap from a premium OEM dome, check the Icon Premium Skylights collection for matched outer dimensions and rise heights. Always cross-reference the part number stamped on your existing dome before ordering.

How do I install a replacement RV skylight?

Remove the old dome by unscrewing the perimeter fasteners and breaking the sealant bond with a putty knife. Clean the roof flange down to bare surface, lay a continuous bead of self-leveling lap sealant or butyl tape, set the new dome, and reinstall fasteners on the original screw pattern. Top the screw heads with lap sealant to prevent water intrusion. Inspect the seal every six months and reseal as needed.

What is shipping like on RV skylights?

Most square skylights ship via standard ground carrier and qualify for free shipping on orders over $100. Larger domes may ship in oversized boxes, so inspect the packaging for cracks before signing for delivery. Need help confirming fitment or shipping timing?

What other roof components should I check while replacing a skylight?

A skylight replacement is a good time to inspect your roof vents, sealant beads, and fan covers. If your Ventline roof vent is cracked or yellowed, the Ventline Vent Essential Accessories collection covers lids, screens, and crank handles. While you have sealant out, walk the full roof and reseal any compromised seams to protect against UV damage and water intrusion.
