Serving Greater Parsippany

Skylight Installation

New and replacement skylights, curb-mounted or deck-mounted, flashed into the roof so they bring in light without bringing in water.

Parsippany Elite Roofing handles skylight installation in Parsippany, NJ and has worked on roofs across the area for more than 20 years, serving surrounding cities including Hanover, East Hanover, Denville, Florham Park and West Caldwell. A skylight can transform a dark hallway, bathroom or upstairs room. It also adds an opening to the roof, and how that opening is framed and flashed decides whether the skylight brings in only light or water as well.

We install new skylights in new openings and replace aging units in existing ones. Every installation uses the manufacturer’s flashing kit, self-adhering ice and water barrier around the frame, and shingles woven back into the flashing. Caulk is never the main line of defense.

Our estimates list the skylight unit, the flashing, any framing work, the interior light shaft and the roofing repairs as separate items. That way you can compare quotes and see exactly what each part of the project costs.

Types of Skylights

Step flashing woven up the side of a new curb-mounted skylight on the rear slope of a Parsippany colonial.

Deck-Mounted Skylights

Deck-mounted skylights attach directly to the roof deck and come with their own integrated flashing system. They sit low on the roof, giving a clean, modern profile. They are the usual choice for new openings on pitched shingle roofs.

Because the flashing is designed for the specific unit, installation follows the manufacturer’s sequence closely. Ice and water barrier wraps the frame before the flashing goes on. The shingles are then woven around it so water runs over the joints, not into them.

Curb-Mounted Skylights

Curb-mounted skylights sit on a raised wooden frame built on the roof deck. The unit fits over the curb, and step flashing seals the curb to the roof. They are common on low-slope roofs and as replacements for older units that already sit on a curb.

Curbs make replacement easier, because a new unit can often fit the existing curb. We check the curb for rot before reusing it. Where it is soft or too short for the snow that collects around it, we rebuild it.

Fixed and Venting Skylights

Fixed skylights do not open and simply bring in light. Venting skylights open manually or with a motor, letting hot air and moisture escape from bathrooms, kitchens and upper floors. Many venting units include rain sensors that close them automatically.

Venting skylights can also help reduce condensation by releasing humid air. We discuss which type suits each room. Shades and blinds are available for both.

New Skylight Openings

Framing the Opening

Adding a skylight where there was none means cutting the roof deck and often a rafter. The opening must be framed with headers and doubled rafters so the roof stays structurally sound. Because this changes the framing, it goes beyond ordinary roof maintenance.

We confirm permit requirements with the local construction office before cutting. The size and location of the skylight are chosen to work with the rafters wherever possible. That keeps framing changes as simple as they can be.

The Light Shaft

Between the roof and the ceiling, a light shaft carries light from the skylight to the room. In homes with an attic, the shaft passes through the attic space and must be insulated and air-sealed. A poorly insulated shaft causes condensation and heat loss.

Shafts can be straight, angled or flared to spread more light into the room. We frame and insulate the shaft, and drywall and finish work can be coordinated with your painter or contractor. The roof side is always fully sealed before interior work begins.

Skylight Replacement and Reflashing

When to Replace a Skylight

Skylights age just like roofs. Fogged glass between panes, cracked or yellowed domes, failed seals and frames that leak at the corners are all signs a unit is near the end of its life. Older domed acrylic skylights are common on homes in the area and are often due for replacement.

Replacing the unit is often the better value when it is leaking and old. A new unit comes with new flashing and current glazing. We explain the difference between repair and replacement before you decide.

Skylights and Roof Replacement

When a roof is replaced, every skylight needs new flashing. That makes roof replacement a natural time to replace older skylights as well. Leaving an old unit in a new roof risks reopening the roof to replace it a few years later.

If the skylight is relatively new and in good shape, we reflash it with a new kit rather than reusing old flashing. Either way, the skylight and the roof are sealed together. That keeps the warranty on both the roof and the unit intact.

Removing an Unwanted Skylight

Sometimes a skylight is no longer wanted, whether because of repeated leaks, heat gain or a remodel. Removing it involves taking out the unit, framing in the opening, installing decking and roofing over it. The interior ceiling is then closed in and finished.

We photograph the framing before it is covered and confirm the structure is sound. The new roofing is woven into the surrounding shingles. Once finished, the old opening is not visible from outside.

Skylights Under Trees and Snow

On wooded lots, leaves and needles collect on the uphill side of a skylight and hold moisture against the flashing. Shaded slopes also grow moss, and a skylight there can stay damp for days after rain. We point out these conditions in the estimate and recommend placement or curb height that helps debris wash past.

In winter, snow banks up against the upper edge of the frame and can feed small ice dams around it. Extra ice and water barrier above the unit and a well-insulated light shaft reduce that risk. Checking the area around the skylight each fall, when leaves are cleared from the gutters, keeps small problems from growing.

Frequently Asked Questions

Do skylights always leak eventually?

No. Most skylight leaks come from flashing that was improperly installed, sealed only with caulk, or reused from an older unit. A skylight installed with the manufacturer's flashing kit and ice barrier around the frame can stay dry for many years. Older units can also fail at the seals around the glass, which is a different repair.

Should I replace my skylight when I replace the roof?

If the skylight is older, has fogged glass or failed seals, or has leaked before, replacing it with the roof is usually the best time. The flashing will be replaced either way, and a new unit avoids opening the new roof again in a few years. Newer skylights in good condition can be reflashed and kept.

What is the difference between curb-mounted and deck-mounted skylights?

A curb-mounted skylight sits on a raised wooden frame built on the roof, and the unit fits over that curb. A deck-mounted skylight attaches directly to the roof deck with its own integrated flashing. Deck-mounted units sit lower and have a sleeker profile, while curb-mounted units are common on replacements and low-slope roofs.

Does adding a new skylight require a permit?

Cutting a new opening changes the roof framing, so it is not treated the same as simply replacing roof covering. Permit requirements depend on the scope and the municipality. We confirm them with your local construction office before any new opening is cut.

What causes condensation on a skylight?

Warm, humid indoor air meeting a cold skylight surface in winter causes condensation, especially in bathrooms and kitchens. It can look like a leak when it drips. Better glazing, ventilation in the room and a properly insulated light shaft all reduce it.

How long does a skylight installation take?

Replacing an existing skylight is usually finished in a single day, including new flashing and the shingles around it. A new opening takes longer, because the framing, light shaft and insulation add work inside the attic. We close the roof up before the end of each day, whatever stage the interior work has reached.
