Hartford Roofing connects you with an independent local roofer for skylight leaks in Hartford and Hartford County. The contractor works out whether the water comes from the flashing, the frame, the glass seal or condensation, then repairs the flashing or replaces the unit, and quotes the work in writing before starting.
A skylight is a hole in the roof with a window in it, and every edge of that hole has to shed water for as long as the roof is there. When a ceiling stain appears beside a skylight, the glass is rarely the first thing a roofer suspects. More often the trouble is the flashing around the frame, the seal between the frame and the roof, or something else entirely, such as moisture from inside the house settling on a cold surface.
Winter in this part of Connecticut makes the question harder. Hartford averages about 49 inches of snow a year, with a January average high of 36 F and a low of 22 F, so a skylight spends a good part of the year with snow piled against its curb and melting at its edges. A leak that never shows in July can start dripping in February, which is why homeowners often discover the problem when snow is on the roof and a roofer is hardest to schedule.
Hartford Roofing is a call line, not a roofing company. You tell the person who answers what you see and where, and you are put through to an independent roofer who serves your town. The contractor inspects, explains the cause and quotes the repair.
Winter leaks usually come from snow and ice, not rain. Snow piled against the frame melts and refreezes, forcing water under flashing that sheds ordinary rain, and indoor moisture condenses on cold glass. A leak that appears only in cold weather can be either, and a roofer can tell which.
Ice dams form when heat escaping into the attic melts roof snow, which then refreezes at the colder eaves. A skylight sits in the roof field, so it can be affected when meltwater backs up under the shingles above and around it. Sealing attic air leaks and improving insulation, as local guidance recommends, helps reduce this. The ice dam removal page covers that side.
Condensation is the other winter suspect. A cold pane with warm, moist indoor air meeting it is a classic recipe for droplets, which can look just like a leak. Run the bath fan, use the kitchen hood, and mention to the roofer when and where moisture appears.
Repair when the unit is sound and only the flashing or sealant has failed. Replace when the glass seal is broken, the frame is warped or stained through, or repeated repairs have not stopped the leak. A roofer's written recommendation should state which and why.
A fogged double pane means the sealed unit has failed, and that part cannot be cleaned out. If the frame is also leaking, replacing the unit and flashing it new often costs less over time than another round of sealant.
Ask the roofer whether the surrounding shingles are near the end of their life. Replacing a skylight just before a re-roof can mean doing the flashing twice, and the contractor may suggest coordinating the work with a planned roof replacement.
A dab of sealant can slow a drip temporarily, but caulk is rarely the lasting fix, and getting onto a roof to apply it is risky. Sealant hides the entry point, ages quickly in sun and cold, and can trap water behind the flashing. A roofer should check before you cover anything up.
If water is coming in, put a bucket under it and move anything valuable out of the way. Take photos of the stain and of any dampness in the shaft, which help the roofer and any later conversation with your insurer.
Layers of caulk from past attempts also make the roofer's job harder, since old sealant has to be removed before new flashing can seat properly.
Do not stand on a roof to inspect or seal a skylight, and never lean on the glass or the dome, which can break under weight. Stay off roofs that are wet, frosted or snow-covered, and keep a bucket and towels in place indoors until a roofer arrives.
The roofer starts inside, looking at the shaft, the ceiling and the frame, and asks when the drip happens: during rain, during a thaw, or only on cold mornings. Those patterns point to different causes.
Moisture on the glass is not always a leak. In a cold spell, warm indoor air from a bathroom, kitchen or humidifier can condense on the glass and frame. If the stain is on the shaft but nothing drips in rain, the fix may be ventilation and sealing, not a roof repair.
On the roof, the roofer checks the flashing at all four sides, the sealant, the shingles or roofing where they meet the frame, and any nearby penetration. Water that runs down the roof can get behind the flashing at the top edge, so the check includes the area above the unit.
A localized repair might mean resealing, re-flashing or replacing a few shingles. If the glass seal has failed, the frame is warped or the unit is old, replacing the whole skylight and flashing it properly is often the lasting fix. The contractor explains which applies and why.
The shaft and ceiling are inspected and, where there is water damage, the roofer notes what is wet. Repairing drywall and paint is usually a separate job from the roof repair.
A fixed unit does not open and has fewer moving parts to fail. A venting unit can be opened by crank or by electric motor and adds a seal around the sash. Both rely on flashing around the frame, and a roofer will identify which type you have before recommending a repair.
These sit on a raised wooden frame built up from the roof, which lifts the unit above water running down the slope. They are common on low-slope roofs and on older homes where a skylight was added later. Curb flashing and the corners of the curb are where leaks start.
These attach directly to the roof deck and come with a flashing kit meant to work with the roof covering. They look neater and are the usual choice on pitched shingle roofs, but the flashing has to be integrated with the surrounding shingles, so a mismatched repair can leak.
A price for skylight work depends so heavily on the unit and the roof that none is published here. Connecticut roofing guides also disagree widely, so figures from them are not repeated.
| Job | Typical range | What it includes |
|---|---|---|
| Resealing or re-flashing an existing skylight | Quoted after inspection | Driven by the size of the unit, the roof pitch and how the old flashing was installed |
| Replacing the glass or sash only | Quoted from the model number | Possible when the frame is sound and the manufacturer still supplies parts |
| Replacing the whole unit and flashing | Quoted in writing before work | Includes roof opening, flashing kit, and tying into the surrounding roofing |
| Repairing the light shaft, ceiling and paint | Separate from the roof work | Drywall and painting are usually a different trade from roofing |
The contractor you reach confirms the price in writing after seeing the skylight, and before any work starts.
Most skylight repair and replacement calls are scheduled the same day when a technician is free, and you approve the price before any work starts.
In West Hartford, the West Hill Drive and Hartford Golf Club districts hold Colonial Revival and Tudor Revival houses built between 1915 and 1936, with steep gables, dormers and chimneys. Where a skylight has been set into a roof of that kind, it has to be flashed into aging roofing and sits close to other roof details, so the age of the roof around the unit matters as much as the age of the unit.
Tall trees are part of the setting in towns like Glastonbury, Bolton and Burlington, and limbs, needles and leaves collect around a skylight curb. Debris that dams water at the upper edge of the frame is a common cause of leaks, so a roofer may suggest clearing it and checking the flashing as part of a visit.
Wind-driven rain is a factor too. The May 2018 microburst north of Hartford and Tropical Storm Isaias in August 2020 are reminders that storm rain can come in sideways, finding gaps in sealant that light rain would never reach.

Leaks usually show up during or just after rain or snowmelt and leave stains at a corner. Condensation tends to appear on cold mornings, forms droplets across the glass and frame, and disappears when the room warms. A roofer can confirm, and may suggest ventilation if there is no actual leak.
Fogging between the panes means the sealed glass unit has failed, so moisture has gotten into the space that should be dry. It is not a roof leak by itself, but it cannot be wiped away. The usual solution is replacing the glass unit or the whole skylight.
A new unit with fresh flashing removes the aged seals and shrunken sealant that cause many leaks, but a skylight is only as watertight as its installation. The roofer's flashing, the underlayment and the integration with the surrounding roofing matter as much as the product.
Cutting a new opening in a roof changes the structure, and the 2022 Connecticut State Building Code requires extra plans for structural changes. Permit rules differ by town, so confirm with the building office and ask the roofer who will pull any permit.
They can add heat loss in the roof plane, and a poorly insulated shaft may warm the snow above. Ice dams mainly come from attic heat, though, and good insulation and air sealing around the shaft help. The attic insulation and ventilation page has more on the cause.
Put a bucket or tub under the drip, move furniture and electronics away, and lay towels to catch overflow. Photograph the damage. Then call in the morning to reach a roofer. Do not climb onto the roof in the dark or in snow to try to fix it.
