Skylight replacement cost
Skylight replacement cost depends on your roof's size, slope and the crew that climbs it, so the range on this page is a start, not a bid. Call (855) 812-6217 during business hours with your ZIP code and ask for skylight replacement cost quotes, and licensed roofers near you price it. Quotes cost nothing and you hire only if you want to.
Skylight replacement cost depends on whether you fix it or swap it. VELUX prices a leaking skylight repair at $300 to $800, framing repair at $170 to $600, and a new motor at $110 to $510.
Nora's skylight is 22 years old and drips in heavy rain. VELUX says its skylights often last 30 years, with warranties up to 20.
Skylight replacement cost by type
| Job | Cost |
|---|---|
| Small parts | $10 to $300 |

| Leak repair or reseal | $300 to $800 |
| Motor on a solar or electric unit | $110 to $510 |
Repair ranges are from the VELUX replacement cost page. A full swap is quoted per unit, by size and type.
Installing a new skylight
A fixed skylight does not open. A venting one opens by crank or motor. A tubular skylight is a small tube that brings light down to a hall or bathroom with no shaft framing.
Cutting a new hole means framing, drywall and paint inside, so skylight installation cost runs above a straight swap. Ask whether the price covers the inside finish.
Flashing and leaks
Most skylight leaks come from the flashing around the frame, not the glass. VELUX puts framing life at 20 to 40 years before the shell corrodes. A new skylight on old flashing will still leak.
Nora's 22-year-old unit is close to the end of that span. Swapping it with a new flashing kit fixes both problems at once.
Doing it with the roof
When the roof comes off, the skylight flashing is open anyway. Replacing the skylight then avoids cutting into new shingles a few years later. Low-E glass also cuts heat gain; ENERGY STAR covers reflective roofing on its cool roof page.
See the roof leak repair page if water is already coming in, or the roofing calculator for the full job.
Questions people ask
Does homeowners insurance cover skylight leaks?
A sudden break from hail or a falling branch is often covered. A slow leak from worn seals or old flashing is wear, and most policies exclude it.
Do skylights need to be replaced when the roof is replaced?
Not always, but it is the cheapest time. VELUX says its skylights often last 30 years; a skylight older than the new roof’s expected life is worth swapping.
Can you just replace the glass in a skylight?
Sometimes. A cracked pane or failed seal can be replaced on some models. When the frame or flashing is the problem, the whole unit comes out.
How much does it cost to replace a skylight?
Repairs run from $10 for small parts to $300 to $800 for a leak, by VELUX. Full replacement depends on size and type and is quoted per unit.
