Skylight Repair Denville, NJ
A roofing contractor in Denville can fix most skylight leaks without replacing the whole unit, starting with the flashing where water usually gets in, once it is clear whether the water is a leak or condensation. Call (862) 421-0116 to reach a local roofer.
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. Sealant that was smeared over the joint years ago dries out and cracks, letting water in on the next hard rain.
Before anything gets torn apart, it is worth ruling out condensation. Condensation shows up on cold days whether it rains or not, while a true leak follows rain or melting snow. 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. Write down when the dripping happens, whether the glass fogs inside or between the panes and whether the stain is at the top or bottom of the shaft. It also helps to know the age of the skylight and whether it was flashed in during the last reroof.
If the problem goes deeper than it first looked, a Denville roofer may also recommend skylight installation or flashing repair.

The skylight repair process
Good skylight work separates leaks from condensation first.
Look at the stains
Stains at the top of the shaft usually point to the head flashing, while drips on the glass point to condensation. A moisture meter helps map how far the water has spread.
Go up 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. If the source is unclear, a slow water test from the roof finds it.
Replace the flashing
New head, side and sill flashing goes in, backed by self-adhered membrane, so the joint sheds water without relying on caulk. This is the repair that fixes most skylight leaks.
Restore the seal
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.
Fix the interior
After the leak is fixed, stained or soft drywall in the light well is repaired. Adding insulation around the shaft can also cut down on condensation.
What is included
Skylight repairs a roofer can handle
Shaft repair
Stained or soft drywall in the light shaft is repaired after the leak is fixed so no trace of the leak remains.

Fogged glass
Glass that has lost its seal is replaced to restore clarity and insulation.
Operator repair
Worn gaskets on venting skylights are renewed so it closes tight in rain.

Skylight Leak Repair Denville, NJ
A lasting skylight leak repair corrects the flashing laps instead of covering them with sealant. The most common fixes are new step flashing along the sides, a new head flashing on the uphill side and clearing debris that dams water above the unit. Caulk alone rarely lasts more than a season or two on a skylight.
If the skylight in your Denville home leaks every time it rains, the flashing is the first suspect. If the roof is due for replacement soon, it may make sense to fix the leak now and replace the skylight with the roof. Ask the roofer to compare repairing now against replacing with the next roof.

Skylight Glass Replacement Denville, NJ
Glass replacement is the fix for a skylight that is dry but cloudy, cracked or hard to see through. Skylight glass is typically tempered on the outside and laminated on the inside, so any replacement should match that safety rating. Plastic domes on older curbs can usually be swapped without touching the roof.
In Denville, glass replacement makes most sense on skylights that are still sound everywhere else. Some skylights allow the sash to be swapped from the roof, while others need the whole unit replaced to change the glass. Low-E coated glass cuts summer heat and keeps the inside pane warmer in winter.

Roofs in this climate
Winters here are long and cold, with snow on the roof for weeks at a time and plenty of nights below freezing. When warm attic air melts the snow, the meltwater runs down and freezes again at the eaves, which is how ice dams form and back water up under the shingles. Coastal storms and heavy spring rain drive water sideways into flashing, valleys and old chimneys. Most homeowners in Denville, NJ have the roof checked in the fall and again after the snow melts.

Skylight Repair questions
Can a leaking skylight be repaired instead of replaced?
A sound skylight with failed flashing can be repaired by replacing the flashing. If the skylight is worn out or the roof is due for replacement, a new unit is often the better choice. The roofer can compare both options once they see the skylight up close.
Why is my skylight leaking?
Leaks usually come from flashing that has loosened, rusted or was sealed with caulk instead of proper laps. Debris piled above the skylight, ice at the head flashing and dried-out sealant are the other common causes. Condensation can look like a leak too, so the timing of the drip matters.
How can I tell condensation from a skylight leak?
Watch when the water appears. Water that shows up during rain or snowmelt is a leak, while beads on the glass on cold, dry mornings are condensation. Running a bathroom fan, lowering indoor humidity and insulating the shaft all help with condensation.
Why is my skylight foggy between the panes?
That haze comes from a failed seal in the double-pane glass. It does not cause a roof leak, but it blocks the view and lowers the insulating value. The roofer can check whether glass alone can be swapped.
Is it smart to replace skylights during a reroof?
Replacing a skylight with the roof makes sense when the unit is more than a few years old or shows any wear. One project avoids tearing into the new roof later to replace an old skylight. A newer skylight in good shape can stay, with fresh flashing installed around it.
