Interior repair
Water damage around the skylight opening is cleaned up and the shaft is insulated if needed.
A roofer in Mountainside can repair a leaking skylight by resealing or replacing the flashing, fixing failed glass seals or replacing a cracked dome, once it is clear whether the water is a leak or condensation. Dial (908) 728-6030 to talk with a local roofer about the skylight.
When a skylight drips, the flashing around the frame is the usual culprit, and the glass is rarely the problem. The skylight sits in a hole cut through the roof, and step flashing along the sides, a head flashing on the uphill side and a sill flashing at the bottom keep water out of that hole. Debris piling up on the uphill side, ice at the head flashing and old sealant that has cracked are the other common entry points.
Before anything gets torn apart, it is worth ruling out condensation. Warm, humid indoor air hits the cold glass in winter, condenses and runs down onto the frame and drywall, which looks just like a leak. A haze trapped between the panes points to a failed glass seal, not a leak, and calls for glass work instead of flashing work.
It helps to watch the skylight for a few days before the roofer comes. Look at whether drips show up with rain, after snow or only on cold days, and where on the frame they start. Say whether it is a venting or fixed unit, and whether it went in with the current roof or an older one.
If the problem goes deeper than it first looked, a Mountainside roofer may also recommend skylight installation or flashing repair.

The inspection starts below, checking the frame, the shaft drywall and the glass for signs of condensation versus leaking. That narrows down where to look on the roof.
On the roof, the roofer checks the step flashing, head flashing and sill flashing, the shingles around the curb and any debris piled on the uphill side. Controlled water testing can pin down which side lets water in.
The shingles around the skylight are lifted, the old flashing removed and new flashing installed in correct laps. For most leaks, reflashing is the whole fix.
Glass with a broken seal is swapped for a new insulated unit, or a cracked acrylic dome is replaced. Some units allow the sash or glass to be replaced without touching the flashing.
Water-stained drywall in the shaft is dried, cut out if soft and refinished. Adding insulation around the shaft can also cut down on condensation.
Water damage around the skylight opening is cleaned up and the shaft is insulated if needed.
Cracked, crazed or yellowed plastic domes are replaced before they let water in.
Leaking flashing is removed and replaced with proper step, head and sill flashing so the roof joint stays dry.
Fogged panes are swapped for a new sealed unit to restore clarity and insulation.
Stuck sashes and failed operators are fixed to stop drafts and leaks.
Fixing a skylight leak means tracing the water to the flashing, the curb, the seals or the shingles around the unit. Most leaks are fixed by reflashing the sides and head, adding ice and water membrane and cleaning out the debris pocket above the skylight. A tube of sealant may slow a leak, but it does not fix one.
If the skylight in your Mountainside home leaks every time it rains, the flashing is the first suspect. An aging skylight on an aging roof is often better replaced than repaired, especially if the glass is fogged too. Ask the roofer to compare repairing now against replacing with the next roof.
When the glass or dome is the problem but the frame and flashing are sound, replacing just the glazing makes sense. Glass skylights usually use insulated glass units, with tempered glass outside and laminated glass inside so broken glass stays in place. Plastic domes on older curbs can usually be swapped without touching the roof.
For Mountainside homes, the age of the unit decides whether new glass is worth it. If parts are no longer made for the unit, replacing the skylight may be simpler than finding glass. Upgrading to low-E glass at the same time can reduce heat gain and condensation.
Around Mountainside, most skylight leaks trace back to worn flashing or sealant that has dried out over the years. Homes in Mountainside and nearby towns like Westfield, Summit, New Providence and Garwood range from decades-old skylights that were caulked in place to newer units with full flashing kits, and each fails in its own way, so having the skylight checked whenever the roof is inspected keeps small leaks from spreading.

Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. Heat escaping from the attic melts snow on the upper roof, and the water refreezes at the colder eaves, building ice dams that push water up under the shingles. Strong coastal storms push rain into every weak spot at the flashing and valleys. That is why roof repair in Mountainside is busiest after a hard winter and before the next one.
A roof problem fixed early rarely spreads to the decking, the insulation or the ceilings.
