Stops Leak Trouble Before It Spreads

When your RV skylight cracks and starts leaking during a storm or you notice water stains forming around the opening, the repair becomes urgent because water doesn't wait. This replacement comes with polycarbonate-safe sealant for installation, so you can apply a continuous seal on the roof surface and finish with a watertight barrier over the flange and fasteners. Once it's installed correctly, you're not chasing drips or watching water work its way into the roof.

Takes the Guesswork Out of Replacement Sizing

A big part of replacing a skylight is confirming the opening size when the old unit doesn't provide clear measurements. This one is sized for a 20" x 8" cutout, with complete outer flange dimensions of 24" x 11", so you have the key measurements before removing the old unit from the roof. That lets you confirm the fit before removing the old unit so you're not stuck mid-project with the wrong size.

Holds Up Better in Constant Sun Exposure

Sun-baked plastic is usually what sends people shopping for another skylight in the first place. This one uses UV-resistant polycarbonate that stands up to sun exposure without cracking or discoloring. Over time, that gives you a skylight that keeps its shape and appearance instead of turning brittle and worn after living on the roof.

Cuts Down Harsh Light Without Losing Natural Brightness

Sometimes the problem isn't just a broken skylight, it's dealing with harsh sunlight and heat building up inside your RV. This smoke-tinted skylight helps reduce glare and manage heat while still allowing natural light into the space. The 4" bubble height raises the skylight above the roofline, allowing light to enter from more angles so your RV still feels bright and open during the day.

Easy Installation with Included Sealant

Get a waterproof install using the included sealant approved for use with polycarbonate plastic. Carefully remove the old skylight, then clean and prep the roof surface so it's dry and debris-free. For additional sealing, you can apply butyl tape (sold separately) along the flange before setting the skylight in place. Secure it with screws (1" zinc or stainless steel screws not included), then use included sealant over the flange edges and fasteners to create a watertight barrier that holds up over time and helps prevent leaks from turning into costly roof repairs. There is an install kit with screws and an additional tube of sealant sold separately (SR76RR).

Note:

• Many sealants on the market, especially self-leveling sealants, contain a chemical known to weaken the polycarbonate. Please use the included sealant for installation. It is safe to use on all roof types and will not damage your skylight investment.
