RV Skylight Sealant Repair

Can I reseal my RV skylight myself with Dicor?

You can reseal a skylight yourself with Dicor, and it holds up fine when the prep is done right. That means removing every trace of the old sealant - not just the loose stuff - with a plastic scraper and solvent, then letting the surface dry a full 24 hours before you lay a new continuous bead.

Where DIY jobs fail most often is incomplete removal and moisture trapped beneath the fresh sealant, which lifts the bead from inside and restarts the leak within one season. Dicor also won't solve a failing gasket - the compression seal between the dome and the frame - so if that rubber is cracked or flat, the sealant is just buying time.

When we come out for a reseal, we pull the dome, inspect the gasket and the substrate underneath for soft spots, and replace what's actually failing before we seal anything back up. Catching a soft spot early runs you a fraction of what it costs after a season of water sitting in the laminate.

How much does it cost to replace an entire RV skylight, not just reseal it?

Full skylight replacement - frame, lens, and all hardware - runs $800-$1,400 installed, depending on the unit size, roof membrane type, and whether the opening needs any wood decking work underneath. That said, most skylight calls we go on don't need a full replacement.

Cracked sealant bead, a dried-out gasket, or a loose flange accounts for the majority of leaks, and that's a repair job, not a swap. We diagnose on-site before recommending anything: if the frame itself is cracked or warped, or a Coleman or Dometic powered vent motor has failed, replacement is the right call.

If the frame is sound, repair typically saves you $600 or more. The edge case to watch for is soft decking around the opening - if water has been sitting long enough to rot the underlayment, that adds framing work before the new unit can go in.

Do you service RV skylights in areas outside our covered metros?

Outside our covered metros, we coordinate repairs through a nationwide certified-tech partner network. When you reach out with your location and RV details, we identify a qualified technician or shop in your area, share the specifics of your skylight issue, and make sure the job gets handled the same way we'd handle it ourselves - leak diagnosis first, then a decision on seal repair versus full dome or lens replacement.

The flat-rate quoting approach carries through to partner jobs, so you get a number before anyone picks up a tool. Response time through the network depends on your location, but we work to get you connected quickly rather than leaving you chasing down a local shop on your own.

What happens if my skylight repair warranty expires and it leaks again?

After 90 days, any new leak is treated as a separate repair job with a fresh diagnosis and a new quote. That's standard practice because conditions outside the original scope - weather stress, UV degradation, neighboring sealant failure, or a vent installation that was already compromised - can open up new pathways that have nothing to do with the work we did.

When you call back, we go through the same process: we get on the roof, trace where water is actually entering, and give you a flat-rate quote before touching anything. Most customers don't need that second call - the repair holds. The best way to stay ahead of this is a roof inspection every two years, where we reseal anything that's starting to lift or crack before it turns into a leak and water gets into the substrate.

Are TPO roofs easier to repair than EPDM or fiberglass?

TPO is the most straightforward to patch - a heat weld fuses the new membrane to the existing surface in minutes with no primer or cure window. EPDM requires a contact cement and primer step, and you need to respect the tack-dry time before pressing the patch or the bond won't hold.

Fiberglass cracks need the surface ground back, an epoxy fill, and a hardening period before you can topcoat. For skylight flashing work specifically, those differences narrow to maybe 30 minutes of labor either way, because the dominant task is cutting out the failed flashing bed, cleaning the deck, and reseating the skylight frame regardless of membrane type.

What actually drives repair cost is how far water has traveled beneath the membrane before you called - a clean flashing failure on dry laminate is a straightforward job, but if the surrounding deck has softened, that becomes a soft-spot repair running alongside the skylight work. We handle all three materials and price flat-rate, so your roof type doesn't change the quote you get up front.

If my RV is still under manufacturer warranty, should I go to the dealer for skylight repair?

Check your warranty terms first, specifically whether roof and skylight components are covered under the coach warranty or a separate supplier warranty - those often have different claim paths. Many dealers won't prioritize skylight work unless it's a documented defect claim, and service wait times at dealerships frequently run one to two weeks or longer.

Our repair won't void your manufacturer warranty - we're doing coach-side maintenance and repair, not drivetrain or chassis work, and we document everything so you have a paper trail if a warranty conversation comes up later. If the damage is clearly a manufacturing defect rather than impact or weather wear, file the claim with the dealer first and let them own that repair on their dime. For everything else - a cracked dome, a failed gasket, a leaking seal around the frame - we can typically get to you faster and at a lower cost than waiting in a dealer queue.

Can you patch a skylight leak if the roof laminate is already soft or delaminating?

If the laminate is soft but still bonded - meaning it compresses under hand pressure but springs back and hasn't lifted or bubbled - we can usually stabilize it. The process is to dry the substrate thoroughly with a heat gun, inject two-part epoxy consolidant into any voids, and then set the new skylight gasket or lens over a proper sealant bed so water can't reenter the same path.

If the laminate has already begun separating - visible bubbles, edges lifting, or a spongy area that doesn't rebound - that's structural delamination, and skylight repair alone won't fix it. At that point you're looking at a roof section replacement, which is a significantly larger job.

The practical lesson: a soft spot caught within the first few months of a leak is almost always patchable. Wait until the laminate separates and the repair scope and cost roughly double.

How do I request an emergency skylight repair in our covered metros?

Call us and tell the dispatcher right away that you have an active leak - that flag moves you to emergency priority. Mention the skylight location on the roof, whether you're seeing water on the ceiling, walls, or floor inside, and roughly how long it's been leaking.

That information lets us pull the right materials before we leave the shop: lap sealant, butyl tape, a replacement lens if yours is cracked, and any interior drywall or ceiling panel supplies. We give you a flat-rate quote over the phone based on what you describe, so there's no surprise on the invoice. Responding fast matters because water doesn't stop at the skylight frame - it wicks into the roof decking, insulation, and ceiling laminate, turning a straightforward seal job into a structural repair the longer it sits.
