The most common type: the metal around the frame has failed or was installed poorly. A new flashing kit and shingles restore the joint. See flashing repair.

Skylights
Skylight Leak Repair: what it covers
Quick answer
A skylight leaks at the flashing around it, at a failed seal in the unit itself or through condensation that only looks like a leak. Washington Roofing connects you with an independent local roofer who finds which it is and repairs or replaces the flashing, the seal or the unit.
A skylight is a hole cut in the roof and covered with glass, so it is always going to be a place where roofing has to be done carefully. The unit sits in a curb or frame, metal flashing laps over the shingles on the sides and under them at the top, and sealant covers the details. Any of those parts can fail, and a leak at the ceiling below may have nothing to do with the glass.
Skylights are most often found on houses that have been renovated or added to, and on rooms with vaulted ceilings or lofts. The Warren County area has plenty of older houses that have been updated, so skylights tend to be later additions cut into older roofs. The skills of the original installer, the age of the roof around it and the climate all affect how the joint behaves.
Washington Roofing is a call line that connects you with an independent local roofer, who does the work. Call (833) 751-2102 and say where the water appears, whether it follows rain or cold weather, and whether the skylight opens. The roofer arranges the visit and checks the flashing, the unit and the roof around it.

How do I tell a skylight leak from condensation?
A leak follows rain or melt and drips from the frame or the ceiling around it. Condensation follows cold, humid conditions, shows as fog or frost on the glass and runs down the well. If moisture appears on a dry cold morning, it is probably condensation.
Condensation is more common than people think, especially in winter in a house with a lot of indoor moisture. It leaves stains in the same place as a leak and is easy to confuse.
Tell the roofer when the moisture appears. That single detail often points the way.
Why do skylight leaks often return after a repair?
Sealant is sometimes used where flashing should have been replaced, and sealant ages quickly in a freeze-thaw climate. A lasting repair resets the flashing in layers with the shingles, which takes more work but holds.
If the roofer's plan is to caulk the frame, ask what happens when the caulk fails. A fair answer includes the limits of caulk.
If the skylight is old, replacing the unit and the flashing together may be the better use of the roof access.
Can a skylight be removed or covered?
Yes, a roofer can remove a skylight and frame in the roof and sheath over the opening, though the interior needs finishing by another trade. This is a permanent change, so consider it carefully and ask whether your town needs a permit.
Some homeowners choose to remove a skylight that leaks repeatedly. The opening is framed in, covered with underlayment and shingled over.
Light and ventilation are lost, so weigh that too.
What does a proper skylight reflashing look like?
Flashing is installed in layers with the shingles: the base at the bottom edge, step pieces up each side woven into the courses and a cap or saddle at the top that sheds water around the unit. Each piece laps over the one below. Sealant is a backup and not the barrier.
Kits are made for particular skylights, and a roofer should use the one that matches your unit. Mismatched flashing is a common cause of repeat leaks.
Ask the roofer to show you the old flashing when it comes off, so you can see what failed.
Can ice and snow cause a skylight to leak?
Yes. Snow sliding down a slope piles against the upper edge of the frame, melts slowly and sits against the flashing, and ice forming around the curb can lift sealant and open gaps. The effect shows after thaws, even when the skylight was dry through summer.
With roughly 30 to 40 inches of snow a year in Warren County, the upslope edge works hard. A small saddle above the frame can split the flow, and a roofer may suggest one.
If the leak appears only in winter, mention that. It narrows the possibilities a good deal.
What should a roofer check around a skylight besides the unit?
The shingles above and beside it, the underlayment, the framing of the curb, the attic side for stains and the insulation in the well. A defect farther up the slope can send water into the skylight area, and wet insulation can hold moisture long after the cause is fixed.
A skylight shaft is a tunnel through the attic, and it is sometimes badly insulated. Cold surfaces in the shaft collect condensation, which can be mistaken for a roof leak.
Checking all of these in one visit saves a second trip and gives you one clear diagnosis.
Warning signs
Signs you need skylight leak repair
Do not stand on or lean over a skylight to inspect it. Glazing can break underfoot, and wet surfaces make the roof slippery.
- Stains on the ceiling around the skylight well or on the drywall splay
- Drips from the frame during rain or snow melt
- Moisture between the panes of glass, which suggests a failed seal
- Condensation or frost on the inside of the glass in cold weather
- Cracked or shrunken sealant around the frame
- Rust or lifted flashing at the sides or the bottom edge
- Shingles around the skylight that are curled or missing
Our process
How our skylight leak repair visit works
Say what you see and when
Tell the line whether the water appears in rain, in snow melt or on cold mornings. The timing helps tell a leak from condensation.
Check the unit and the flashing
The roofer looks at the glass, the frame, the seals and the metal around it, and at the shingles above and beside it.
Check the roof above
Water often runs down the slope toward a skylight from a higher defect. The roofer looks upslope as well as at the unit.
Repair or replace
Flashing may be reset or replaced. A unit with a failed seal or a rotted frame may need to be replaced, and the roofer should explain why.
Finish the interior side
The roofer checks the well and the insulation, and tells you what to do about stained drywall, which is usually someone else's trade.
Options
Types and options for skylight leak repair
Failed unit seals
Moisture between the panes means the unit has failed and is not a roof leak. The glass is replaced, not the flashing.
Condensation
Warm, damp indoor air meets cold glass and drips. The fix is humidity control and ventilation, not roofing. A roofer can tell you whether it is likely.
Cost
How much does skylight leak repair cost in Washington?
No price is printed for skylight work. It depends on the type of unit, the roof pitch and whether the unit or only the flashing needs replacing. The roofer confirms it on site.
| Job | Typical range | What it includes |
|---|---|---|
| Reflash or replace the unit | Decided at inspection | A new flashing kit costs less than a whole unit |
| Type and size of skylight | Set by the unit | Fixed, opening and tubular units differ |
| Roof pitch and height | Measured on site | Steep roofs add safety work |
| Shingles around the unit | Judged on site | They often need lifting or replacing |
| Interior repair | Separate trade | Drywall and paint are usually not the roofer's |
Your exact price is confirmed on site before any work starts.

Tell us what's happening and we'll tell you honestly whether it's a quick fix, and what skylight leak repair should cost.
Warren County
Why skylight leak repair is different in Warren County and the Delaware Valley
Roughly 45 inches of precipitation a year falls in Warren County, per the county statistics page, and a skylight sits in the path of all of it. Snow can slide down and pile against the upslope edge of the frame.
Where a skylight was added to a house built in 1939 or earlier, as with many of the 1,572 of 6,233 units in ZIP 07882, the roof around it may be older than the unit, and repairs need to take that into account.
Pennsylvania addresses, such as Easton and Bangor, are under the Attorney General's contractor registration once annual work reaches $5,000.

FAQ
Skylight Leak Repair FAQs
Should I replace the whole skylight?
If the seal has failed or the frame has rotted, yes. If only the flashing has failed, the roofer can often reflash and keep the unit.
Does a skylight need a permit to replace?
That is a question for your municipal construction office. Replacing like for like may differ from cutting a new opening.
Can I fix a skylight leak with caulk?
It might hold briefly but rarely for long. See roof leak repair for how leaks are traced.
Why does my skylight drip in winter only?
Possibly condensation or ice backing up at the frame. The roofer can tell by the timing.
Can a leak be fixed in winter?
Temporary measures often can, but some repairs wait for milder weather. The roofer will advise.
